Death of Taxpayer Final Tax Return: The 2026 Executor’s Playbook for Form 1040, Form 1041, Form 706, and the §1014 Stepped-Up Basis
The decedent’s final Form 1040
IRC §6012(b)(1) requires the personal representative (executor, administrator, or surviving spouse) to file the decedent’s final Form 1040 covering income from January 1 through date of death.
Filing deadline. Same as a regular Form 1040 — April 15 of the year following death. Extensions available via Form 4868. So a decedent dying in 2026 has final Form 1040 due April 15, 2027 (with extension to October 15, 2027 if extended).
Who signs. The personal representative signs the return. Write ‘DECEASED’ across the top of the return with date of death. The personal representative’s signature, title (executor, administrator), and date.
Filing status. The decedent’s filing status for the year of death depends on marital status: (1) MFJ if the surviving spouse files jointly with the decedent. (2) Single if unmarried. (3) HoH if qualifying. (4) MFS if the spouses were filing separately.
MFJ for year of death. The surviving spouse can file MFJ with the decedent for the year of death (and the year before if not yet filed). Combines the decedent’s income (Jan 1 to death) with the surviving spouse’s full-year income on one return. Usually the most tax-favorable option.
Two-year rule for MFJ with deceased spouse. The surviving spouse can file MFJ for the year of death and the year before. The year after death, the surviving spouse files as ‘Qualifying Widow(er) with Dependent Child’ if they have a qualifying dependent child — uses MFJ brackets and standard deduction for 2 more years. Without a qualifying child, the surviving spouse files single starting the year after death.
Income reported. All income received by the decedent from January 1 through date of death is reported on the final 1040. Wages earned through date of death. Interest and dividend income through date of death. Capital gains realized through date of death. Self-employment income. Pension and Social Security received.
Income earned but not received before death — Income in Respect of Decedent (IRD). Under §691, IRD is NOT reported on the decedent’s final return. Instead, IRD is reported by whoever ultimately receives the payment after death (typically the estate or beneficiary). Examples of IRD: unpaid wages, dividends accrued but not received, traditional IRA balances, deferred compensation, installment notes, accrued interest on bonds.
Standard deduction. Full standard deduction available even if death occurs early in the year. The decedent gets the full annual standard deduction ($15,000 single in 2026 estimate, $30,000 MFJ).
Itemized deductions. If decedent itemized in prior years, can still itemize on final return. Medical expenses paid in the year of death AND medical expenses paid within 1 year after death are deductible on the decedent’s final return (special election under §213(c)) — covered in dedicated section.
Credits. Decedent’s eligible credits flow to the final return. CTC, education credits, EIC if income was low enough, etc. Just normal credit rules.
Tax owed on final return. Paid from the decedent’s estate, not by the personal representative personally. The estate is the source of payment.
Medical expenses paid in the 1-year window — §213(c)
Medical expenses paid by the personal representative within 1 year after the decedent’s death are deductible on the decedent’s FINAL return — not on the estate’s Form 1041. This is the §213(c) election.
§213(c). ‘Amounts paid for the medical care of the decedent which are paid out of his estate during the 1-year period beginning with the day after the date of his death, and the amounts are not deducted as estate expenses, shall be treated as paid by the taxpayer at the time incurred.’
So if the decedent died in March 2026 and the estate paid $50,000 of hospital bills in October 2026 (within 1 year of death), that $50,000 is deductible on the decedent’s final 2026 Form 1040 (as medical expense subject to 7.5% AGI floor).
If the medical expense had been incurred but not yet paid, this gets the expense out of the income limitation that applies to estate-level medical expense deduction (which is more restrictive).
The 1-year window is critical. Medical bills paid 13 months after death don’t qualify for §213(c). They go on the estate’s Form 1041 or are estate administrative expenses.
Election. The §213(c) treatment requires a formal statement attached to the decedent’s final return: ‘The personal representative elects to deduct on the decedent’s final Form 1040 the medical expenses paid by the estate within 1 year after the decedent’s death, totaling $X. The amounts are not deducted on the federal estate tax return (Form 706).’ The estate gives up deducting the same expenses on Form 706. So the election is a tax-arbitrage choice.
When to make the election. The election is favorable when (a) the decedent had high AGI on final return (deduction at high marginal rate) and (b) the estate doesn’t need the deduction on Form 706 (estate is below exemption threshold).
When NOT to elect. (a) Estate is over the federal exemption and needs the deduction on Form 706 (estate tax rate higher than income tax rate). (b) Decedent’s AGI was low and the 7.5% floor disallows the deduction anyway.
Example. Decedent dies March 2026 with $50K of medical bills incurred pre-death but unpaid. Estate pays them in 2026. Decedent’s final 1040 AGI: $200,000. With §213(c) election: $50K deductible (after $15K floor) = $35K deduction. At 24% marginal rate: $8,400 federal tax savings. If decedent’s AGI were $30K (low income decedent), the 7.5% floor of $2,250 disallows less of the deduction, but the savings at 12% marginal rate is smaller ($5,700).
Strategy. For most decedents below the federal estate tax exemption ($7M-$14M), the §213(c) election is favorable. Document and elect.
If estate is above exemption. The federal estate tax rate is 40% (top bracket). If deducting medical expenses on Form 706 saves at 40% rate, and deducting on final 1040 saves at most at 37% rate, Form 706 deduction is slightly better. Calculate both.
Common medical expense scenarios for §213(c). (1) Final hospital stay. Decedent admitted in February, dies in March. Hospital bills $80,000 paid by estate in April. Deductible on decedent’s final 1040 under §213(c). (2) Nursing home bills. Last 6 months of care, $50,000. Paid by estate post-death. Deductible. (3) Hospice care. Often Medicare-covered, but some out-of-pocket. Deductible portion only. (4) Funeral and burial. NOT medical expenses. Not deductible on final 1040. Deductible on Form 706 estate tax return (under §2053).
Deathbed gifts and §213(c). Pre-paying medical expenses during decedent’s life to capture deduction on final return. Not always advisable — if the payment doesn’t actually pay medical bills, may not qualify.
Estate’s Form 1041 — income tax return for the estate
After date of death, income earned by the estate (interest, dividends, gain on sale of estate assets, IRD) is reported on the estate’s Form 1041 income tax return.
§641 and following. The estate is a separate taxable entity for income tax purposes. Files Form 1041. Pays income tax on retained income. Distributes income to beneficiaries who report it on their own returns.
Calendar year vs fiscal year. The estate can elect a fiscal year ending on the last day of any month following date of death. §441(c). Calendar year is simpler. Fiscal year provides flexibility for income recognition timing.
Estate’s basic filing requirement. Gross income $600 or more in the taxable year triggers Form 1041 requirement. §6012(a)(3).
Tax computation. Estate uses compressed tax brackets (37% rate kicks in above $15,200 in 2026 — extreme compression compared to individual rates). Distributions to beneficiaries reduce estate’s taxable income (through the distribution deduction) and shift income to beneficiaries at their individual rates.
Distribution strategy. Distributing income to beneficiaries usually saves total family tax because beneficiaries’ marginal rates are typically lower than the estate’s compressed rates. Plan distributions intentionally.
Income in Respect of Decedent (IRD). Items the decedent earned but didn’t receive before death are IRD. Examples: unpaid wages, accrued bond interest, traditional IRA balance, deferred compensation, annuity payments due.
IRD reported on Form 1041 (estate’s return) when received by the estate. Then potentially distributed to beneficiaries (who report on their own returns). The IRD retains its tax character — ordinary income IRD remains ordinary; capital gain IRD remains capital gain.
IRD doesn’t get §1014 stepped-up basis. §691(c). IRD assets keep the decedent’s basis. So a traditional IRA inherited by an heir doesn’t get stepped-up basis — the heir continues with the decedent’s basis.
Section 691(c) deduction. The recipient of IRD gets a deduction equal to the federal estate tax attributable to the IRD. So if the estate paid $40,000 of federal estate tax on $100,000 of IRD (40% rate at top), the IRD beneficiary deducts $40,000 against the IRD income.
Section 691(c) calculation. (Estate tax with IRD) – (Estate tax without IRD) = Estate tax attributable to IRD. The IRD beneficiary claims this as an itemized deduction (not subject to 2% floor; itemized deduction).
Estate’s tax year. Estate can have a long tax year (over 12 months for newly created entities) but limited. Generally the estate closes within 3 years of date of death. Some estates remain open longer for complex administration.
Estate’s deductions. Administrative expenses (legal fees, executor fees, accounting fees), property taxes, mortgage interest on estate property, charitable distributions to qualified charities. Deductions on Form 1041 reduce taxable income.
Section 1014 stepped-up basis — the inheritance basis windfall
IRC §1014 gives inherited property a ‘stepped-up’ (or stepped-down) basis equal to fair market value at date of death (or alternate valuation date 6 months later, if elected).
How it works. Decedent owned 100 shares of Apple bought for $50/share in 2005. FMV at death in 2026: $300/share. Decedent’s basis: $5,000. FMV at death: $30,000. Heir’s basis: $30,000 (stepped up). If heir sells immediately at $30,000, no gain.
Effect. The lifetime appreciation in the property is wiped out for income tax purposes. The heir starts with a fresh basis at FMV.
Cost to government. $42 billion annually (CRS estimate). Largest ‘loophole’ in the income tax code. Has been targeted for elimination but politically untouchable so far.
Stepped-DOWN basis. If FMV at death is less than decedent’s basis, basis steps DOWN. So a $5,000 basis stock worth $3,000 at death has basis of $3,000 for the heir. Built-in losses are eliminated — but built-in gains are also eliminated. Generally not optimal to die holding losing positions (heir loses the loss).
Joint tenancy. For property held in joint tenancy with right of survivorship between spouses, special rules. Community property states: full step-up on both halves at first spouse’s death (§1014(b)(6)). Equitable distribution states: half step-up (only the deceased spouse’s half steps up).
Community property states stepup is hugely valuable. Spouses in CA, TX, WA, etc., get full step-up on jointly-held property at first death. Equitable distribution states only get half.
Alternate valuation date. §2032 election. Estate can elect to value assets 6 months after date of death instead of at date of death. Election generally favorable if asset values dropped in the 6 months post-death. Election must reduce both gross estate AND estate tax (so not available if no estate tax is owed).
Reasonable cause for basis records. The heir needs documentation of FMV at date of death. Appraisals for hard-to-value assets (real estate, closely-held businesses, art, collectibles). Stock prices for publicly-traded securities (Yahoo Finance historical prices). The basis is set at this moment; heir relies on this for future sales.
Step-up doesn’t apply to IRD. Section 691 IRD items keep decedent’s basis. So a traditional IRA inherited has decedent’s basis (typically zero for traditional IRA contributions) — no step-up.
Step-up applies to Roth IRA. Roth IRA distributions are tax-free under §408A — basis is essentially irrelevant. But the §1014 step-up technically applies.
Step-up applies to ETFs, mutual funds. Stepped up to FMV at death. Each share’s basis steps up individually.
Step-up applies to real estate. Personal residence stepped up to FMV at death. Inherited home sold soon after at the stepped-up value: minimal gain. Long-held rentals with decades of depreciation: step-up wipes out the depreciation gain too.
Step-up for partnership interests. §1014 applies to outside basis in partnership. Inside basis adjustment requires §754 election by the partnership. Complex; specialty attorney for partnership/LLC interests in decedent estates.
Refund claims and Form 1310 for the decedent
If the decedent’s final Form 1040 shows a refund, the personal representative must use Form 1310 to claim the refund on behalf of the estate.
Form 1310 — Statement of Person Claiming Refund Due a Deceased Taxpayer. Attached to the decedent’s final return when a refund is being claimed.
Filing categories.
Box A. Surviving spouse filing MFJ. Box checked on Form 1040; no Form 1310 needed.
Box B. Personal representative (executor, administrator, or court-appointed individual) with court-certified appointment. Court certification document required.
Box C. Person claiming refund on behalf of deceased taxpayer when there is no court-appointed personal representative. Need a Will or other document showing entitlement. Form 1310 must be filed; refund check made out to claimant’s name.
Without Form 1310. The IRS will issue refund check made out to the decedent. This check cannot be cashed (banks won’t process a check to a deceased person). The check becomes problematic to resolve.
With Form 1310. The IRS issues the refund check in the name of the person filing Form 1310. The check is processable.
Specifically what to file. Form 1310 with the appropriate box checked. Death certificate. Court appointment papers (if applicable). Mail with the decedent’s final tax return or separately if the return has already been filed.
Multiple personal representatives. If multiple executors/administrators, each can file Form 1310 individually or jointly. Most common: one designated personal representative files.
Refund check delivery. Form 1310 instructs the IRS to mail the refund check to the address on the Form 1310. Verify the address is correct.
If the surviving spouse remarried before the refund check arrives. Doesn’t affect the refund. Refund is for the year of decedent’s death, the surviving spouse at that time gets the refund. Remarriage doesn’t change.
State refund equivalent. Most states have equivalent forms for state tax refund claims. Check state-specific procedures.
Time to file. Form 1310 can be filed any time after the tax return is filed. Refund claim must be made within the §6511 statute of limitations: 3 years from filing date of original return or 2 years from payment of tax, whichever is later.
Pension and annuity considerations at death. Pension benefits that were ‘paying out’ to decedent stop at death (annuity terminates) or continue to surviving beneficiary depending on payment form. Joint and survivor annuity continues at reduced payment to surviving spouse. Single life annuity terminates.
Lump-sum distributions from retirement plans. Some decedents had taken lump-sum distributions before death — already in 1040. Some plans require beneficiary to receive lump-sum after death — typically rollover to inherited IRA to avoid immediate taxation.
Section 691 IRD reporting timing. IRD is reported when received by the estate or beneficiary. So even if the underlying right to receive existed at death, the income tax recognition is at later receipt. Allows planning of recognition timing across years.
Estate tax — Form 706 and the portability election
If the decedent’s gross estate exceeds the federal estate tax exemption (or the executor wants to make a portability election), the estate must file Form 706 — United States Estate (and Generation-Skipping Transfer) Tax Return.
Federal estate tax exemption. §2010. 2026 exemption (Rev. Proc. 2024-40): approximately $13.99 million (the TCJA-doubled amount before sunset). Pre-TCJA sunset would lower to about $7 million in 2026. Post-2025 depends on Congressional action. Most analysts expect extension.
Estate tax rate. 40% on taxable estate above the exemption.
Gross estate. §2031 defines gross estate as the value of all property in which the decedent had an interest at death. Real estate, securities, bank accounts, business interests, life insurance proceeds (if decedent owned the policy), retirement accounts, joint property (decedent’s half), property over which decedent had general power of appointment, certain gifts within 3 years of death.
Deductions from gross estate. §2053 funeral expenses. §2054 losses during administration. §2056 marital deduction (unlimited for transfers to surviving spouse). §2055 charitable deduction (unlimited for transfers to qualified charities). Debts and claims against the estate.
Taxable estate = gross estate – deductions. Estate tax = 40% × (taxable estate – exemption).
Marital deduction. Transfers to surviving citizen spouse are unlimited deductible. Major benefit. Many estates have zero estate tax because of unlimited marital deduction.
Charitable deduction. Transfers to qualified charities are unlimited deductible.
Portability election. §2010(c)(4). The ‘Deceased Spousal Unused Exclusion’ (DSUE). Allows the surviving spouse to use the decedent’s unused estate tax exemption.
How portability works. First spouse to die uses $5M of exemption (out of $14M available); $9M unused. Surviving spouse can add the $9M to their own exemption. Combined effective exemption for surviving spouse: $14M (own) + $9M (DSUE) = $23M.
Portability election timing. Election made on Form 706. Form 706 due 9 months after date of death (extension via Form 4768 to 15 months). For estates below the exemption that don’t otherwise need to file Form 706, can file a simplified Form 706 just to elect portability. Rev. Proc. 2022-32 provides relief for late filings up to 5 years after date of death.
Why portability matters. Without portability election, the surviving spouse loses the deceased spouse’s unused exemption. For estates that combined exceed $14M (or whatever the exemption is at the surviving spouse’s death), the loss of DSUE costs 40% × (combined estate – $14M-$23M) = potentially millions of dollars.
Strategic considerations. For estates clearly under the exemption now ($14M combined), portability may seem unnecessary. But if estate values grow significantly (real estate, business, retirement accounts), and the exemption shrinks (post-2025 TCJA sunset), portability becomes critical. File the election as a precaution.
State estate and inheritance taxes — varying landscape
Federal estate tax is just one layer. Many states have their own estate or inheritance tax with different exemptions, sometimes much lower than federal.
States with state estate tax (or inheritance tax) as of 2026 (approximately). Connecticut ($13M exemption), Hawaii ($5.49M), Illinois ($4M), Maine ($6.41M), Maryland ($5M plus inheritance tax), Massachusetts ($2M), Minnesota ($3M), New York ($7M with cliff), Oregon ($1M), Rhode Island ($1.77M), Vermont ($5M), Washington ($3M), DC ($4M). Estate tax rates typically 10-16%.
Inheritance tax states (tax on beneficiary). Kentucky, Maryland (in addition to estate tax), Nebraska, New Jersey, Pennsylvania. Rates depend on relationship to decedent (spouse exempt; siblings and others may be taxed at various rates).
Massachusetts $2M cliff. MA has a particularly tough estate tax. The exemption is $2M. But it’s a ‘cliff’ — if estate exceeds $2M by $1, the tax is calculated on the full amount (not just the excess). So a $2,000,001 estate owes estate tax on $2,000,001, not $1. Resulting effective tax can be 15%-20% of estate.
Oregon $1M exemption. One of the lowest. Estate tax begins immediately on any estate over $1M.
Washington $3M exemption. Estate tax 10-20%. Plus a separate excise tax on real estate transfers.
New York $7M with cliff. Similar to MA. If estate exceeds $7M by 5%, no exemption — full tax on full estate.
Multi-state estates. Real estate in multiple states. Each state taxes estates owning property in that state. Death in one state but real estate in another: filing in multiple states.
Domicile vs residency. Estate tax follows decedent’s domicile. Moving from a high-estate-tax state to a no-estate-tax state pre-death saves estate tax — if the move is genuine domicile change.
Domicile change near death. State revenue departments aggressively challenge late-life domicile changes. Florida is the prototypical ‘estate tax move’ destination — establishing FL domicile genuinely (not just as a tax shelter) is hard if you’re already terminally ill.
Estate tax planning. Lifetime gifts (within gift tax exemption $19K annual per donee 2026), charitable bequests, irrevocable trusts (intentionally defective grantor trust, qualified personal residence trust, grantor retained annuity trust), life insurance trusts. Each has its own complexity.
QDOT for non-citizen surviving spouse. §2056A. Non-citizen surviving spouse doesn’t get unlimited marital deduction. Workaround: assets pass to a Qualified Domestic Trust. QDOT distributes income to non-citizen spouse during life; estate tax deferred on distributions until QDOT terminates.
Final return income items and what gets reported where
The mechanics of who reports what.
Wages received before death. Reported on decedent’s final 1040 (Schedule 1 line 1 or Form 1040 line 1).
Wages earned but unpaid at death. IRD. Reported by the recipient (estate or beneficiary) on Form 1041 or beneficiary’s 1040. Section 691 IRD characterization.
Interest received before death. Decedent’s final 1040, Schedule B.
Interest accrued but not received before death. IRD. Estate or beneficiary reports.
Dividends paid before date of record before death. Decedent’s final 1040.
Dividends with record date or payment date after death. Estate or beneficiary reports.
Capital gains from sales completed before death. Decedent’s final 1040, Schedule D.
Capital gains from sales completed after death. Estate or beneficiary reports. Basis is stepped-up under §1014, so gain calculation is from stepped-up basis.
Pension and Social Security received before death. Decedent’s final 1040.
Pension and SS earned but unpaid at death. IRD. Estate or beneficiary reports.
Traditional IRA distributions before death. Decedent’s final 1040.
Traditional IRA balance at death. Not on decedent’s final 1040. Inherited IRA continues for beneficiary. Distributions from inherited IRA reported by beneficiary on their 1040.
Roth IRA distributions before death. Generally tax-free (qualified distributions) under §408A.
Roth IRA balance at death. Inherited Roth IRA continues. Distributions tax-free if qualified (5-year rule consideration).
Self-employment income through date of death. Decedent’s final 1040, Schedule C. SE tax applies up to wage base.
Capital gain distributions from mutual funds. Reported by whoever was holder of record on date of record. If held by decedent on date of record before death: decedent’s 1040. If held by estate after death: estate’s 1041.
Stock dividends and stock splits before death. Just a basis adjustment, no income event. New shares carry adjusted basis.
Foreign income. Same allocation rules. Earned before death goes on decedent’s 1040; earned after on estate’s 1041. Foreign tax credits available.
Beneficiary reporting and the K-1 from the estate
When the estate distributes income to beneficiaries, the income passes through and is reported by the beneficiary on their own return.
K-1 from Form 1041. The estate issues a Schedule K-1 to each beneficiary who received distributions. The K-1 reports the beneficiary’s share of estate income items.
K-1 line items. Interest, dividends, capital gains, rental income, royalty, business income, IRD items. Each character type is reported separately.
Beneficiary’s tax. The beneficiary reports the K-1 income on their own Form 1040. Same character as if earned directly: interest as interest, dividends as dividends, capital gains as capital gains, IRD as ordinary income with §691(c) deduction.
Distribution deduction at estate level. The estate deducts the amount of income distributed to beneficiaries on Form 1041 line 18 (distribution deduction). Reduces estate’s taxable income.
Tier 1 vs Tier 2 distributions. Tier 1: required income distributions (like a marital trust requiring all income to surviving spouse). Tier 2: discretionary distributions. Tax accounting at estate level may differ.
Sixty-five day rule. §663(b). Distributions made within 65 days after end of estate’s tax year can be treated as if made on the last day of the previous year. Useful for year-end planning — allows pushing distributions into a prior year for tax purposes.
Election. Made on Form 1041 line 7 by checking the box. Treats distributions in first 65 days of new year as previous year’s distributions.
Beneficiary’s holding period for inherited assets. §1223(9). Inherited assets are always considered long-term, regardless of how long the beneficiary holds them. So a beneficiary who sells inherited stock 6 months after inheritance gets long-term capital gain treatment.
Beneficiary’s basis. Stepped-up basis from §1014. Beneficiary’s basis is FMV at date of death (or alternate valuation date). For IRD items, no step-up — beneficiary takes decedent’s basis.
Multiple beneficiaries. Each beneficiary’s K-1 reports their proportionate share. The estate must allocate income items proportionally based on the will, trust terms, or other instruments.
Specific bequests. §663(a)(1). Specific bequests of property aren’t treated as distributions of income — they’re simply transfers of property. The beneficiary takes stepped-up basis but no estate K-1 income.
Residuary beneficiary. The beneficiary of the residue gets the leftover after specific bequests. K-1 income to residuary beneficiary is the proportion of total estate income allocable to residue (after specific bequests).
Beneficiary’s reporting on Form 1040. K-1 items flow to specific lines: interest on Schedule B, dividends on Schedule B, capital gains on Schedule D, rental income on Schedule E, business income on Schedule C if active business income.
Common errors and audit issues on final returns
Most personal representatives are family members handling a final return for the first time. Errors are common.
Error 1: Failing to file. The decedent’s final 1040 must be filed even if income was minimal. Failing to file leaves the case open with the IRS and complicates estate closing.
Error 2: Filing too early or late. Final return due April 15 of year after death. Personal representatives sometimes file the return prematurely (missing late-arriving 1099s) or late (missing the deadline). Use Form 4868 extension if needed.
Error 3: Failing to claim §213(c) medical expenses. The 1-year window allows medical expenses paid post-death to be deducted on the final 1040. Often missed by family members.
Error 4: Missing portability election. Estate just under federal exemption skips Form 706. Surviving spouse loses DSUE. Can be expensive if estate growth or exemption changes later.
Error 5: Incorrect basis for inherited assets. Heirs sometimes use decedent’s basis instead of stepped-up FMV. Overpays tax on sale.
Error 6: Missing IRD items. IRD continues to be reported by estate or beneficiary. Sometimes IRD items go unreported (the family doesn’t know about an annuity, deferred comp, or retirement account).
Error 7: Not getting court-certified executor papers. Form 1310 requires court-certified appointment papers if Box B is checked. Family delays in probate cause delays in tax filings.
Error 8: Incorrect filing status. Surviving spouse should file MFJ for year of death. Sometimes the family files as MFS or single, losing the MFJ benefit.
Error 9: Missing Form 706 election deadlines. Multiple deadlines on Form 706: due date 9 months after death (extended to 15 months), portability election, special elections like alternate valuation date.
Error 10: Failing to obtain decedent’s prior-year returns. The personal representative needs prior-year returns to identify carryforwards (NOL, capital loss, charitable, etc.), basis records, etc. Sometimes lost or hard to access.
Audit risk. The IRS does audit estate returns. Common audit issues: valuation of closely-held businesses (lowballed by estate to reduce estate tax), valuation of real estate (similarly), missing IRD items, undisclosed gifts within 3 years of death.
Strategies to reduce audit risk. Get qualified appraisals for hard-to-value assets. Document basis with prior tax returns. File all required forms. Make elections timely. Engage a CPA familiar with estate and trust taxation.
Penalties for late filing. Section 6651 failure-to-file penalty: 5% of unpaid tax per month, max 25%. Failure-to-pay: 0.5% per month, max 25%. Interest at §6621 underpayment rate (currently 8%).
Statute of limitations. Generally 3 years from filing date. Extended to 6 years for substantial omission (over 25% of gross income). Indefinite for fraud.
Personal representative’s personal liability. §6901(a). The personal representative can be personally liable for the decedent’s tax debts if they distribute estate assets to beneficiaries before paying tax. Discharge mechanism via Form 5495 (Request for Discharge from Personal Liability) protects the personal representative.
Joint tenancy with non-spouse joint tenants. Decedent’s portion of jointly-held property is includable in gross estate based on proportional contribution under §2040(a). If decedent and child held property as joint tenants, decedent’s contribution (typically full purchase price if decedent funded the purchase) is included. Child’s contribution (typically zero) is not.
Spousal joint tenancy. Different rule under §2040(b). Half of jointly-held property between spouses is included in decedent’s gross estate, regardless of contribution. Stepped-up basis applies to half (or full in community property states).
Charitable bequests and §170 income tax deduction at the estate level
If the decedent made charitable bequests in their will, the estate gets income tax deductions for amounts paid to qualified charities under §170.
Estate-level charitable deduction. The estate deducts on Form 1041 charitable distributions to qualified §501(c)(3) organizations. Unlimited deduction (no AGI floor at estate level for §1041 charitable deductions).
Charitable bequest vs IRD-funded charitable gift. If the estate uses IRD assets (like a traditional IRA) to fund the charitable bequest, the IRD income is offset by the charitable deduction at the estate level. Net result: zero income tax on the IRD that goes to charity.
Strategic implication. Direct IRD assets to charitable beneficiaries rather than non-charitable beneficiaries. The IRD doesn’t get §1014 step-up, so non-charitable beneficiaries pay full income tax on receipt. Charitable beneficiaries are tax-exempt, so no income tax. Save the IRD for charity.
Charitable Remainder Trust (CRT) at death. The estate funds a CRT with appreciated assets or IRD. CRT distributes income stream to non-charitable beneficiaries for life or term of years; remainder to charity. Estate gets immediate income tax deduction for charitable portion (PV of charity’s interest). Non-charitable income stream taxed to beneficiaries as received.
Charitable Lead Trust (CLT). The reverse — CLT distributes to charity for term of years, then remainder to non-charitable beneficiaries. Estate-friendly because the gift to non-charitable beneficiaries is discounted by the value of the charitable lead. Used for estate planning purposes more than income tax.
Qualified Charitable Distributions (QCD). For taxpayers age 70.5 and over, QCDs from traditional IRA directly to charity (up to $108,000 in 2026 indexed) satisfy RMD without including in income. Doesn’t help decedent at death but useful during life.
Bargain sale to charity. Decedent’s estate sells appreciated asset to charity at below FMV — gets a charitable deduction for the bargain element. Allows estate to recover some cash while making a charitable gift.
Section 642(c) deduction. Estates and trusts get a §642(c) deduction for amounts permanently set aside for charity. Different from current-year distribution. The set-aside doesn’t have to be paid out immediately; just designated for charity.
Trusts at death — revocable vs irrevocable trust handling
Many decedents had trusts as part of their estate plan. The trust treatment varies based on whether revocable or irrevocable.
Revocable living trust. Established during decedent’s life, decedent retained right to modify or revoke. At death, the trust becomes irrevocable. Assets held in revocable trust are included in decedent’s gross estate for estate tax purposes (because decedent had power to revoke).
Income tax treatment of revocable trust. During decedent’s life: grantor trust, all income taxed to decedent. After decedent’s death: trust becomes irrevocable and gets its own tax return. The trust files Form 1041 for years after decedent’s death. Same calendar year or fiscal year election.
Trust EIN. The trust needs its own EIN once it becomes irrevocable (after decedent’s death). Apply via SS-4. Different from the estate’s EIN.
Irrevocable trust established during life. Already had own tax filing obligation. At decedent’s death, trust continues to operate per trust terms. Decedent’s grantor trust status (if any) terminates at death. Trust may convert from grantor to non-grantor trust status, with implications for income tax filing.
Inclusion in gross estate. Irrevocable trusts may or may not be included in gross estate depending on retained powers. §2036 (retained life estate), §2038 (retained power to alter), §2041 (general power of appointment) — these provisions include certain irrevocable trusts in gross estate.
Step-up at death. §1014 stepped-up basis applies only to property included in gross estate. So irrevocable trust assets NOT in gross estate don’t get stepped-up basis. Important planning consideration — assets in grantor irrevocable trusts may not get step-up.
Section 1014(b)(2) and (b)(3). Specific basis rules for trust property included in gross estate.
QPRT (Qualified Personal Residence Trust). Personal residence transferred to trust. At decedent’s death, residence excluded from gross estate (transferred during life under §2702 rules). Step-up doesn’t apply. Built-in gain remains in the trust assets.
GRAT (Grantor Retained Annuity Trust). Annuity retained by grantor; remainder to beneficiaries. At grantor’s death, GRAT assets pass to beneficiaries without estate tax (if grantor survives the GRAT term).
IDGT (Intentionally Defective Grantor Trust). Trust treated as grantor trust for income tax but irrevocable for estate tax. Grantor pays income tax on trust earnings during life. At death, trust assets excluded from gross estate but no §1014 step-up.
Charitable Remainder Trust (CRT). Income stream to non-charitable beneficiary; remainder to charity. At death of decedent, CRT continues. Trust’s tax-exempt status preserves growth tax-deferred.
Beneficiary designations override the will
Beneficiary designations on retirement accounts, life insurance, and certain other assets transfer outside of probate. The will doesn’t control these assets — the beneficiary designation does.
Retirement account beneficiary designations. 401(k), IRA, 403(b), pension. The named beneficiary on the account inherits directly. Bypasses probate. The will’s provisions for retirement accounts are usually ineffective (the account-level designation controls).
Spousal protection for qualified plans. ERISA requires spousal consent for non-spouse beneficiary designations on qualified retirement plans (401(k), pension). Without spousal consent, the spouse is the default beneficiary regardless of named beneficiary.
IRAs not subject to ERISA. Spousal consent not required for non-spouse beneficiary on IRA. So decedent could name a sibling, child, or other non-spouse as IRA beneficiary without spouse consent.
Life insurance beneficiary designations. Similar mechanic. Named beneficiary receives proceeds outside of probate. Proceeds generally tax-free under §101(a) for income tax purposes. May be includable in gross estate for estate tax (if decedent owned the policy under §2042).
Joint tenancy with right of survivorship. Property passes to surviving joint tenant automatically. Bypasses probate. Doesn’t follow the will.
POD (Payable on Death) and TOD (Transfer on Death). Bank accounts and brokerage accounts with POD/TOD designations transfer directly to named beneficiaries. Bypasses probate.
Outdated beneficiary designations. Common problem. Decedent named ex-spouse as beneficiary years ago, never updated. Even though decedent’s will leaves everything to current spouse, the retirement account passes to ex-spouse. The court won’t override beneficiary designation in most cases.
Beneficiary designation review. Get all beneficiary designations updated when life events occur: marriage, divorce, birth of child, death of beneficiary, change of estate plan. Routine annual review.
Multiple beneficiaries. Designations can include primary and contingent (secondary) beneficiaries. If primary predeceases, contingent gets the asset. Pro-rata sharing among multiple primary beneficiaries.
Per stirpes vs per capita. Per stirpes: if a beneficiary predeceases, their share goes to their descendants. Per capita: if a beneficiary predeceases, their share is divided equally among the remaining living beneficiaries. Decedent should specify which method applies.
Decedent’s debts and the personal representative’s role
The decedent’s debts must be paid from the estate before assets are distributed to beneficiaries. The personal representative manages this process.
Identifying debts. Notice to creditors in state-mandated newspaper publications (typically 30-90 days). Direct outreach to known creditors. Review of decedent’s records, mail, credit reports.
Order of payment. State law specifies order of payment from estate assets. Generally: (1) administrative expenses (court costs, executor fees, attorney fees, appraisals), (2) funeral and burial expenses, (3) federal taxes (income, estate, gift), (4) state and local taxes, (5) secured debts (mortgages with lien on specific property), (6) unsecured debts (credit cards, personal loans, medical bills), (7) general creditors.
Insolvent estates. If debts exceed assets, the estate is insolvent. Personal representative pays in order of priority until funds run out. Lower-priority debts go unpaid. Beneficiaries get nothing.
Surviving spouse protection. Many states have laws protecting surviving spouse from being made homeless by debts. Marital home in many states has homestead protection.
Discharge of debts. Bankruptcy discharge survives death — debts discharged in life remain discharged. Debts incurred during life that weren’t discharged are still payable from estate.
Joint debts. If both spouses are obligors on a credit card, mortgage, or other debt, the surviving spouse is still liable. Decedent’s death doesn’t discharge the joint obligation.
Authorized user vs co-applicant. An authorized user on a credit card is not legally liable. A co-applicant or joint cardholder is liable. Important distinction for surviving spouse.
Funeral and final expenses. Funeral, burial, cremation, headstone, memorial services. All payable from estate. Tax-deductible on Form 706 estate tax return (if filed) under §2053.
Personal representative’s liability. §6901(a)(1). Personal representative can be personally liable for unpaid federal taxes if estate assets are distributed to beneficiaries before paying tax. Discharge mechanism via Form 5495 protects the personal representative.
Notice to IRS. Form 56 — Notice Concerning Fiduciary Relationship. Filed by personal representative to notify the IRS of their fiduciary capacity. Provides notice that the rep is responsible for the decedent’s tax matters going forward.
Tax discharge for personal representative. Form 5495 — Request for Discharge from Personal Liability under §2204. After paying all taxes, personal representative requests discharge from personal liability. Protects from later assessments.
Statute of limitations on tax claims. IRS has 3 years (extended to 6 years for substantial omission) to assess tax. Personal representative shouldn’t distribute estate assets until tax matters are resolved or sufficient reserves set aside.
Pre-death planning to reduce final return complexity
Several moves during life simplify the final return and reduce overall family tax burden.
1. Roth conversions during low-income years. Convert traditional IRA to Roth during a low-income year (between jobs, after retirement before SS claim, sabbatical). Pay tax now at lower rate; Roth grows tax-free; heirs inherit Roth tax-free. Eliminates IRD tax burden on traditional IRA balance.
2. Qualified Charitable Distributions (QCDs) from IRA. For age 70.5+, up to $108,000/year (2026 indexed) directly from IRA to charity. Counts toward RMD. Not includible in income. Reduces IRA balance that would otherwise be IRD at death.
3. Lifetime gifts within annual exclusion. $19,000 per donee per year (2026 estimate). $38,000 if married couple. Reduces gross estate over time. Tax-free to donor and donee.
4. Lifetime gifts within lifetime exemption. Beyond annual exclusion. $14M lifetime exemption (2026 estimate). Use during life if appreciation is expected. Locked-in current low values rather than future high values.
5. Tax-loss harvesting. Realize capital losses during life to offset gains. Don’t die holding loss positions (step-down basis eliminates the loss).
6. Realizing gains in 0% LTCG bracket. Below $96,700 MFJ (2026 estimate) of taxable income, LTCG taxed at 0%. Realize gains to reset basis higher at low cost.
7. Capital gain harvesting via bunching. Pull a year of capital gain into a year of low income.
8. Charitable beneficiary designations for IRD assets. Name charity as IRA beneficiary. Charity is tax-exempt; IRA passes tax-free. Save IRD-loaded assets for charity, taxable assets for non-charitable beneficiaries.
9. Update beneficiary designations regularly. Annual review. Coordinate with overall estate plan.
10. Family limited partnership / LLC. Discount valuations for minority interests passing to non-managing family members. Common estate planning vehicle.
11. Life insurance trust (ILIT). Removes life insurance from gross estate. Provides liquidity for estate tax payment without inflating estate.
12. Spousal lifetime access trust (SLAT). Each spouse creates trust for the other. Removes assets from gross estate while preserving access during life.
13. Generation-skipping transfer planning. Allocate GST exemption to gifts to grandchildren. Avoids future estate tax at children’s level.
14. Estate plan documentation. Centralized location for all estate planning documents — wills, trusts, beneficiary designations, prior tax returns, deeds, appraisals. The personal representative will need access to all of these. Cloud storage (encrypted) plus paper backups at multiple locations. Inform the personal representative of the location during life. Many estates suffer delays because the personal representative can’t find the original will.
15. Final tax planning point. Encourage your decedent (during life) to talk openly with you about their estate plan, document locations, and any unusual assets or accounts. Many estates encounter problems because the personal representative is unaware of certain accounts, debts, or planning structures. Communication during life prevents costly discovery after death.

Frequently Asked Questions
My father died in March 2026. As executor, what tax returns do I need to file and when?
As executor, you’ll typically need to file the following returns within specific deadlines. 1. Decedent’s final Form 1040 — covering income from January 1, 2026 through March (date of death). Due April 15, 2027 (with extension via Form 4868 to October 15, 2027). Reports wages, interest, dividends, capital gains, retirement distributions, and other income through date of death. 2. Estate’s Form 1041 — annual income tax return for the estate, starting on March (date of death) and covering income received by the estate through year-end (December 31, 2026, if estate uses calendar year) or through estate’s fiscal year-end (estate’s choice). Filing deadline is the 15th day of the 4th month after estate year-end (April 15 for calendar year). For estates electing fiscal years, deadline varies. 3. Federal Estate Tax Return Form 706 — if gross estate exceeds the federal exemption (2026 ~$13.99M expected, lower if TCJA sunsets) OR if portability election is being made. Due 9 months after date of death (extended to 15 months via Form 4768). Even if no estate tax is owed, file Form 706 if portability is desired. 4. State estate tax returns — if state has its own estate tax. Each state has own deadlines and exemptions. Many states (CT, IL, MA, MD, MN, NJ, NY, OR, RI, VT, WA, DC) have estate or inheritance taxes with deadlines typically 9-12 months after death. 5. State income tax returns — for the decedent’s final state Form 1040 equivalent and for the estate’s state income tax return. Each state has its own forms and deadlines. 6. Form 1310 — Statement of Person Claiming Refund Due Deceased Taxpayer. Attached to decedent’s final 1040 if claiming a refund. Box A if you’re the surviving spouse filing MFJ; Box B with court appointment papers; Box C without court appointment. 7. Form 56 — Notice Concerning Fiduciary Relationship. Filed by the personal representative to notify the IRS of their fiduciary capacity. File within reasonable time of appointment. 8. SS-4 — Application for Employer Identification Number for the estate. The estate is a separate taxpayer; needs its own EIN. Apply online at IRS.gov. EIN required for Form 1041 filing and for opening estate bank accounts. Process. (1) Obtain court appointment papers from probate court (typically 4-8 weeks post-death in most states). (2) Apply for estate EIN. (3) Identify all income items through date of death and post-death. (4) Identify assets and FMV for §1014 basis stepping. (5) Notify financial institutions of death. (6) Open estate bank account. (7) Pay decedent’s bills and final expenses. (8) File final 1040 by April 15, 2027. (9) File Form 1041 quarterly estimated payments if estate has significant income. (10) File estate Form 1041 by April 15 of year after estate year-end. (11) File Form 706 if needed by December 2026 (9 months post-March 2026 death). Time pressure. Form 706 has the earliest hard deadline (9 months). Address this first. The 9-month deadline can sneak up. Get a qualified appraiser engaged early for any hard-to-value assets (real estate, business interest, art). Engage professionals. CPA familiar with estates (different from regular tax prep). Estate attorney if assets are complex or estate is over exemption. Appraiser for real estate, business, art, collectibles. Investment advisor for portfolio management during administration. Coordination. Personal representative coordinates with all professionals. Maintain a master schedule of deadlines. Keep beneficiaries informed (also have legal obligations to do so under state probate law). Common deadlines to track. (1) Form 1310 with final 1040 — within filing deadline. (2) Form 706 — 9 months from death. (3) Final 1040 — April 15 of year after death. (4) Form 1041 — varies by estate year-end. (5) §213(c) medical expense election — with final 1040. (6) Portability election on Form 706 — 9 months from death (with extension). (7) Alternate valuation date election — on Form 706 within 6 months of due date. (8) Special use valuation under §2032A — on Form 706. (9) State estate tax — varies, typically 9-12 months. Document organization. Create a master file. Sections: decedent’s personal info (SSN, date of death, death certificate), prior years’ tax returns (5+ years if available), asset list with values at death, debts and creditors, income items (Forms 1099, W-2), receipts for funeral and medical expenses, court appointment papers, EIN documents, beneficiary contact info. Engage a CPA who handles estates. The work is technical and error-prone. A general tax preparer may miss the nuances. AICPA Personal Financial Planning Section or NACVA-accredited specialists handle estate work. Cost. Decedent’s final 1040: $500-$1,500. Form 1041 annual: $1,000-$3,000. Form 706: $3,000-$10,000+ depending on complexity. Multi-state filings add cost. Appraisals separately ($500-$5,000 each). Additional practical advice. Engage professionals early — CPA, attorney, appraiser. The cost of doing it right ($5K-$15K typically for a moderate estate) is far less than the cost of mistakes ($30K-$200K+ in unnecessary taxes for common errors). Keep beneficiaries informed throughout the process. Document every decision and election in writing. Maintain the estate accounting separately from your personal records. Don’t rush distributions before tax matters are resolved. The IRS has 3 years to audit (longer for fraud or substantial omission); maintain reserves for potential adjustments. Common executor mistakes to avoid. Distributing assets too early before all taxes are paid (personal liability). Missing the §213(c) medical expense election deadline. Failing to file Form 706 portability election (loses DSUE). Using decedent’s basis instead of stepped-up FMV. Missing IRD items. Incorrect filing status on final 1040. Not getting court-certified executor papers. Missing state estate tax filing deadlines. For a more typical $1M-$5M estate, the work is manageable but requires careful coordination. For estates over $14M, get a specialized estate attorney and CPA team early. Timeline expectations. Most moderate estates close within 12-18 months. Complex estates (litigation, valuation disputes, multi-state assets) take 2-5 years. Form 706 deadline at 9 months drives much of the early-stage urgency. Investment management during administration matters — keep the portfolio prudent and document the rationale for investment decisions. Don’t underestimate the time commitment. Personal representative duties typically require 100-300 hours of work over the estate administration period for moderate estates.
How does the stepped-up basis work, and how do I document FMV at date of death?
Section 1014 stepped-up basis is one of the largest tax benefits in the code. The heir takes property with basis equal to fair market value at date of death (or alternate valuation date 6 months later, if elected). Documentation of FMV is critical because the heir will rely on this basis for future sales. Mechanics. Decedent owned 1,000 shares of XYZ Corp purchased for $30,000 in 2005. FMV at death March 15, 2026: $250,000. Heir’s basis under §1014: $250,000. If heir sells immediately at $250,000: zero gain. Decades of appreciation eliminated from income tax. Stepped-down basis. Same mechanic applies if FMV is below decedent’s basis. Decedent’s basis $200,000; FMV at death $150,000. Heir’s basis: $150,000. Built-in loss eliminated. What gets stepped up. Capital assets generally. Real estate, stocks, mutual funds, ETFs, bonds, business interests, art, collectibles, vehicles, jewelry, retirement accounts (Roth IRA, not traditional IRA). What doesn’t get stepped up. (1) Income in Respect of Decedent (IRD). Traditional IRAs, deferred compensation, accrued interest, unpaid wages, installment notes — these keep decedent’s basis under §691. (2) Property held in revocable trust same as outside the trust (full step-up). (3) Property held in irrevocable trust — step-up only if includible in gross estate (depends on trust terms). (4) Annuities — exception applies; cost basis follows specific rules. FMV documentation requirements. The IRS expects qualified appraisals for hard-to-value assets. For audit-defensible basis, obtain. Publicly-traded securities. Use closing price on date of death. If date of death is a non-trading day (weekend, holiday), use the closing price on the next trading day or use a weighted average of the prior and next trading day prices (some practitioners use weighted average). Yahoo Finance and other historical price sources document this. Real estate. Qualified appraisal by a licensed real estate appraiser. Should be a formal written appraisal report following USPAP standards (Uniform Standards of Professional Appraisal Practice). Cost $500-$2,000 typically. Includes comparable sales, condition assessment, and supporting documentation. Why a formal appraisal? IRS may challenge the basis on subsequent sale by the heir. If the heir sold for $400K and claimed $400K basis (alleged FMV at death), the IRS could argue that FMV at death was only $350K and the gain is $50K. Without documentation, the heir loses the argument. With a formal appraisal showing $400K FMV at death, the heir’s position is defensible. Closely-held businesses. Specialty business valuation. ASA, CPA, ABV, NACVA-accredited business valuators. Cost $5,000-$25,000 depending on complexity. Methods: discounted cash flow, comparable transactions, asset-based. Discounts for lack of marketability and lack of control may apply. Art, antiques, collectibles. Qualified appraisal by relevant specialist. Auction house valuations or specialty appraisers (American Society of Appraisers Art Section). Cost varies. Personal property. Furniture, household goods, jewelry under $5,000 each: typically no formal appraisal needed; fair estimate sufficient. Jewelry/items over $5,000: formal appraisal recommended. Hard-to-value financial assets. Promissory notes, private equity interests, hedge fund investments: get a formal valuation. Alternate valuation date election. §2032. Estate can elect to value assets 6 months after date of death instead of at date of death. Election made on Form 706. Only available if (a) the alternate date reduces gross estate, AND (b) the alternate date reduces estate tax. So if no estate tax is owed, the election isn’t available (technically, but you’d elect on Form 706 anyway for portability purposes). Why alternate date helps. If market declined in the 6 months post-death, asset values at alternate date are lower than date of death. Reduces gross estate, reduces estate tax. But heir’s basis is also reduced (stepped down further). Trade-off: lower estate tax vs lower basis. Joint property considerations. Property held in joint tenancy with right of survivorship between spouses: special rules. Community property states: full step-up on both halves at first spouse’s death under §1014(b)(6). Equitable distribution states: half step-up. Joint property with non-spouse joint tenants. Decedent’s share included in gross estate proportional to contribution. The decedent’s portion gets step-up; the surviving joint tenant’s contribution doesn’t. Holding period after inheritance. Section 1223(9) — inherited property always considered long-term, regardless of how long beneficiary holds. So heir who sells inherited stock 3 months after inheriting gets long-term capital gain rates. Recordkeeping. Maintain documentation file with: death certificate, appraisals or valuation reports, account statements showing FMV at date of death (or alternate valuation date), basis worksheet for each asset, journal entries showing the basis step-up, any 1014 elections made on Form 706. Documentation lasts forever. The heir may sell decades later. The basis needs to support reporting whenever the sale occurs. Maintain records as long as the asset is held, plus the §6501 statute of limitations after sale. Practically: maintain forever. What if FMV documentation is missing or weak? The IRS may impose its own valuation. The taxpayer’s burden of proof on basis. Without documentation, the IRS can use whatever valuation it wants. Often unfavorable. Best practice. Get appraisals as soon as possible after death. Memories fade. Records get lost. Conditions change. Document immediately and store securely. Additional practical advice. Engage professionals early — CPA, attorney, appraiser. The cost of doing it right ($5K-$15K typically for a moderate estate) is far less than the cost of mistakes ($30K-$200K+ in unnecessary taxes for common errors). Keep beneficiaries informed throughout the process. Document every decision and election in writing. Maintain the estate accounting separately from your personal records. Don’t rush distributions before tax matters are resolved. The IRS has 3 years to audit (longer for fraud or substantial omission); maintain reserves for potential adjustments. Common executor mistakes to avoid. Distributing assets too early before all taxes are paid (personal liability). Missing the §213(c) medical expense election deadline. Failing to file Form 706 portability election (loses DSUE). Using decedent’s basis instead of stepped-up FMV. Missing IRD items. Incorrect filing status on final 1040. Not getting court-certified executor papers. Missing state estate tax filing deadlines. Appraisal cost considerations. The cost of qualified appraisals ($500-$5,000 each) is far less than the potential tax cost of inadequate basis documentation. Don’t skimp here. Get qualified appraisals from licensed professionals to defend basis on later sales.
What’s Income in Respect of Decedent (IRD), and why does it matter for an inherited IRA?
Income in Respect of Decedent (IRD) is income the decedent had earned but not yet received before death. Under IRC §691, IRD doesn’t get §1014 stepped-up basis. The recipient (estate or beneficiary) reports the IRD as ordinary income when received, retaining the same tax character it would have had to the decedent. Examples of IRD. (1) Unpaid wages — earned by decedent but unpaid at death. (2) Accrued bond interest — earned through date of death but not yet paid. (3) Dividends declared but not yet paid as of date of death. (4) Traditional IRA balances — pre-tax retirement money. (5) Deferred compensation (401(k), 403(b), pension, supplemental executive retirement plans). (6) Annuity payments due but not yet paid. (7) Installment notes receivable — payments due but not yet received. (8) Final commissions or bonuses. (9) Royalties earned but not yet paid. (10) Lottery winnings annuitized over multiple years (payments after death). Why the IRA is the most important IRD item for most families. The deceased contributed to a traditional IRA over a working lifetime — pretax dollars. The IRA balance at death is potentially $200K, $500K, $1M+ depending on individual circumstances. All this is IRD when distributed by the beneficiary. Traditional IRA: no step-up. Distributions taxable to beneficiary at beneficiary’s marginal rate as ordinary income. SECURE Act adds 10-year payout requirement for most beneficiaries (non-spouse, non-EDB). Roth IRA: §1014 step-up technically applies but irrelevant. Roth distributions are tax-free (if 5-year rule satisfied). Heir takes Roth IRA at FMV at death but distributions are tax-free regardless. Example comparison. Decedent had $500K of pretax traditional IRA and $500K of Roth IRA. Heir (non-spouse, non-EDB) receives both. 10-year payout under SECURE Act applies to both. Traditional IRA distributions: $500K of ordinary income taxed at heir’s marginal rate over 10 years. At 32% marginal: $160K of federal tax. Plus state tax. After-tax inheritance from traditional IRA: $340K. Roth IRA distributions: $500K of tax-free distributions over 10 years. Total tax: $0. After-tax inheritance from Roth IRA: $500K. Roth IRA is worth $160K more than equal-value traditional IRA to the heir. Significant. Pre-death Roth conversions. Decedent could convert traditional to Roth before death — pay tax during life at potentially lower rates, leave Roth to heirs tax-free. Common estate planning strategy. Section 691(c) deduction. The heir who reports IRD gets a deduction equal to the federal estate tax attributable to the IRD. This is an itemized deduction (not subject to 2% miscellaneous floor; specific §691(c) treatment). Calculating §691(c) deduction. (Federal estate tax actually paid with IRD) – (Federal estate tax that would have been paid without IRD) = §691(c) deduction. Spread over the years the IRD is recognized. Example. Estate had $30M of assets including $5M of IRD (traditional IRA). Federal estate tax with IRD: $6.4M. Without IRD: $4.4M. §691(c) deduction: $2M. If the IRD beneficiary receives $1M of IRD in year 1: deduction is $1M / $5M × $2M = $400,000. So beneficiary has $1M of ordinary income offset by $400K of §691(c) deduction = $600K net. At 37% marginal rate: federal tax $222K. Without §691(c): $370K tax. Saves $148K in year 1. Importance. The §691(c) deduction prevents double taxation — first by federal estate tax (40% of $5M IRD) and then by federal income tax (37% of $5M IRD). Without §691(c), combined federal tax would be ~62% of the IRD. With §691(c), the income tax portion is reduced. Section 691(c) doesn’t apply to state income tax. So state taxes the IRD without offset for federal estate tax. Significant burden on IRD beneficiaries in high-tax states like CA, NY, NJ. If estate isn’t above exemption. No federal estate tax paid; no §691(c) deduction. IRD is taxed at full ordinary rates to beneficiary. Reporting IRD. Estate reports IRD on Form 1041 when received. Then distributes to beneficiaries via K-1. Beneficiary reports on their Form 1040 (Schedule 1 line 24z ‘other income’ for IRD items not classified elsewhere; or on appropriate Schedule B/D depending on character). IRD character. IRD retains its tax character. Ordinary income IRD (wages, IRA distributions, deferred comp) is ordinary. Capital gain IRD (gain on installment notes from prior sales) is capital gain. Interest IRD is interest. Tax-exempt IRD (rare) is tax-exempt. Traditional IRA RMD year of death. The decedent’s RMD for the year of death isn’t required to be taken before death. The IRS rules under §401(a)(9) allow the year-of-death RMD to be taken by either the decedent (before death) or the beneficiary (after death) — must be taken by end of year of death by someone. 10-year payout rule for inherited IRAs. SECURE Act applies to deaths after 2019. Beneficiary must empty inherited IRA within 10 years (or follow EDB stretch if applicable). Detailed in separate post. Annuity IRD. Annuity payments due to the decedent at death are IRD. The beneficiary continues receiving the annuity and reports as IRD. Installment note IRD. Decedent sold an asset on installment, was receiving payments over time. At death, remaining payments due are IRD. Beneficiary recognizes income as payments are received. Retains the original gain character from the sale. Deferred compensation IRD. 401(k) balance, 403(b) balance, pension, supplemental retirement plans. All IRD. Subject to inherited retirement account rules under SECURE Act. Strategic planning. (1) Pre-death Roth conversion to convert IRD to non-IRD. (2) Charitable bequests of IRD (QCDs in life or charitable beneficiary at death) to avoid IRD taxation entirely. (3) Spread IRD recognition across years and beneficiaries to minimize compressed tax. (4) Make the most of §691(c) deduction in years of highest IRD distribution. Documentation. Identify all IRD items at death. Track for life of the estate. Allocate to beneficiaries via K-1 reporting. Calculate §691(c) deduction for each beneficiary’s allocation. Additional practical advice. Engage professionals early — CPA, attorney, appraiser. The cost of doing it right ($5K-$15K typically for a moderate estate) is far less than the cost of mistakes ($30K-$200K+ in unnecessary taxes for common errors). Keep beneficiaries informed throughout the process. Document every decision and election in writing. Maintain the estate accounting separately from your personal records. Don’t rush distributions before tax matters are resolved. The IRS has 3 years to audit (longer for fraud or substantial omission); maintain reserves for potential adjustments. Common executor mistakes to avoid. Distributing assets too early before all taxes are paid (personal liability). Missing the §213(c) medical expense election deadline. Failing to file Form 706 portability election (loses DSUE). Using decedent’s basis instead of stepped-up FMV. Missing IRD items. Incorrect filing status on final 1040. Not getting court-certified executor papers. Missing state estate tax filing deadlines.
My grandmother died with $10M in assets. Do we need to file Form 706 for the estate tax return?
At $10M, you’re below the 2026 federal estate tax exemption (currently $13.99M expected, before potential TCJA sunset). Federal estate tax not owed. But you should still file Form 706 for the portability election, plus check state estate taxes. Federal exemption analysis. 2026 federal estate exemption: $13.99M for individuals (TCJA-doubled amount per Rev. Proc. 2024-40). Pre-TCJA sunset would lower to ~$7M for 2026. Post-2025 Congressional action determines whether sunset occurs. Most analysts expect extension. Your $10M estate is below $13.99M. No federal estate tax owed. Form 706 not required by §6018(a) for filing purposes. But — portability election. If grandmother was married and her husband (your grandfather) survived her, OR if she pre-deceased him and her husband still survives, portability election preserves the unused exemption for the surviving spouse. Portability mechanic. Grandmother used $10M of exemption ($10M of taxable estate). Unused exemption: $3.99M ($13.99M – $10M). Surviving spouse can claim this via Deceased Spousal Unused Exclusion (DSUE) when filing their own estate tax return. So surviving spouse effectively has $13.99M + $3.99M = $17.98M of exemption available. If grandmother was widowed (your grandfather pre-deceased her), portability doesn’t apply for her estate. Her estate uses her own exemption. If portability matters. Estate growth, exemption shrinkage. If your grandfather had $10M and grandmother left another $10M, joint total $20M. Without portability, surviving spouse’s $13.99M exemption covers $13.99M of that — the remaining $6.01M is taxable at 40% = $2.4M of estate tax at second death. With portability, no estate tax (combined exemption $17.98M covers the full $20M). Portability filing requirement. Even if no estate tax is owed, file Form 706 to make the portability election. §2010(c)(5)(A). Filing deadline. Form 706 due 9 months after death (extended to 15 months via Form 4768). For estates not otherwise required to file Form 706 but making portability election: Rev. Proc. 2022-32 provides relief for late filings up to 5 years after death. Very generous extension. Don’t miss this. Simplified Form 706 for portability-only filing. The IRS allows a simplified Form 706 filing for estates below the exemption that just want to make portability election. Less complex than a full Form 706 with valuation supporting documentation. But still requires valuation of estate assets sufficient to demonstrate the estate is below exemption. Typical CPA cost for portability-only Form 706: $2,000-$5,000. State estate tax. Check grandmother’s state of domicile. State estate tax exemptions vary widely. Connecticut: $13M (close to federal). Hawaii: $5.49M (below federal). Illinois: $4M (well below). Maine: $6.41M. Maryland: $5M plus inheritance tax. Massachusetts: $2M (the killer — cliff exemption). Minnesota: $3M. New York: $7M with cliff. Oregon: $1M (one of the lowest). Rhode Island: $1.77M. Vermont: $5M. Washington: $3M. DC: $4M. If grandmother lived in MA, NY, OR, IL, or similar low-exemption state, she may have substantial state estate tax. State Form 706 equivalent due, typically 9-12 months after death. State estate tax rates 10-16%. Income tax considerations beyond estate tax. Form 1040 (final). Form 1041 (estate income). State income tax equivalents. Section 1014 step-up. Even though no federal estate tax is owed at $10M, all inherited capital assets get stepped-up basis to FMV at date of death. Major benefit. Document FMV with appraisals. Form 706 elections. Even when filing for portability only, certain other elections may be valuable. (1) Alternate valuation date — generally not available if no estate tax owed. (2) §2032A special use valuation for family farms or closely-held businesses — usually not applicable for portability-only filing. (3) Generation-skipping transfer tax allocations. GST tax. Generation-Skipping Transfer Tax exemption: $13.99M (matches estate exemption). If grandmother’s bequests include any to grandchildren or beyond, GST analysis. Skip-person allocations on Form 706. Beneficiary planning. The $10M of inherited assets pass to beneficiaries. Beneficiaries take stepped-up basis. Selling soon after inheritance: minimal gain. Holding long-term: future gain from stepped-up basis. Trust considerations. If grandmother had a revocable living trust holding most assets, the trust assets pass per trust terms. Trust assets typically included in grandmother’s gross estate (revocable trust). Stepped-up basis applies. The trust becomes irrevocable at her death. Trust may need its own EIN and Form 1041 going forward. Beneficiary K-1s. Estate (or trust) issues K-1s to beneficiaries when distributing income. Beneficiaries report on their own 1040s. Recommendation. (1) File simplified Form 706 for portability election if applicable. (2) Confirm state estate tax filing requirements. (3) Obtain qualified appraisals for FMV at date of death documentation. (4) Identify all IRD items and inheritance vehicles. (5) Engage a CPA familiar with estates ($3K-$8K for typical $10M estate work). (6) Keep beneficiaries informed of K-1 reporting and basis records. Additional practical advice. Engage professionals early — CPA, attorney, appraiser. The cost of doing it right ($5K-$15K typically for a moderate estate) is far less than the cost of mistakes ($30K-$200K+ in unnecessary taxes for common errors). Keep beneficiaries informed throughout the process. Document every decision and election in writing. Maintain the estate accounting separately from your personal records. Don’t rush distributions before tax matters are resolved. The IRS has 3 years to audit (longer for fraud or substantial omission); maintain reserves for potential adjustments. Common executor mistakes to avoid. Distributing assets too early before all taxes are paid (personal liability). Missing the §213(c) medical expense election deadline. Failing to file Form 706 portability election (loses DSUE). Using decedent’s basis instead of stepped-up FMV. Missing IRD items. Incorrect filing status on final 1040. Not getting court-certified executor papers. Missing state estate tax filing deadlines. State estate tax planning is often more impactful than federal at moderate estate sizes ($1M-$10M). MA and OR are particularly aggressive. Plan around state-specific rules. Multi-state real estate complicates further. Final reminder. The 5-year late portability election relief under Rev. Proc. 2022-32 is generous but not infinite. Don’t rely on it; file portability within the normal 15-month window if possible. Surviving spouse circumstances change; better to lock in the DSUE early. Practical example. Grandmother dies in 2026 with $10M estate. Surviving grandfather has $5M of his own. Combined potential estate at second death: $15M-$20M (with growth). Without portability, grandfather’s $14M exemption covers but barely. With portability of grandmother’s $4M unused exemption: $18M combined exemption. Excess covered.
I’m the surviving spouse and my husband died in 2026. Should I file MFJ for 2026 and what does ‘qualifying widow’ mean?
Yes — file MFJ for 2026 (the year of your husband’s death). The qualifying widow(er) status is a special filing status that allows you to use MFJ brackets and standard deduction for 2 additional years after death if you have a qualifying dependent child. Year of death (2026) filing options. (1) MFJ — combines your full-year income with husband’s January-March income on one joint return. Usually the most favorable. (2) MFS for your separate income; husband’s separate return for his January-March. (3) HoH if you qualify (typically requires being unmarried, but the considered-unmarried rule under §7703(b) might apply if husband moved out 6+ months before death — uncommon). Recommendation. File MFJ for 2026 if you and husband had typical marriage tax dynamics. MFJ benefits: wider tax brackets, $30,000 standard deduction (vs $15,000 single), eligibility for more credits and deductions. Mechanics of MFJ for year of death. You file Form 1040 with status ‘Married Filing Jointly.’ Report all of your income for the full year. Report husband’s income from January 1 through date of death. Add your incomes together. Subtract $30,000 standard deduction. Apply MFJ brackets. Husband’s name and SSN on return. Both names appear. Husband’s SSN as joint filer. Write ‘DECEASED’ across the top of the return, with husband’s date of death. Signature. You sign as ‘surviving spouse.’ If court has appointed you as executor/administrator, you also sign as personal representative. Refund considerations. If joint refund is due, Form 1310 isn’t needed (Box A on Form 1310 — surviving spouse filing MFJ). The IRS issues the refund check in your name. Estimated payments coordination. If you and husband made joint estimated payments during 2026, those payments are credited to the joint return. No special allocation needed. After 2026 — Qualifying Widow(er) status. §2(a)(1)(A)(i) defines ‘surviving spouse’ for purposes of qualifying widow(er) status. Available for 2 years after the year of spouse’s death if you meet requirements. Requirements for QW status. (1) Spouse died in 2024, 2025, or 2026 (one of the prior 2 tax years, plus year of death allows MFJ). (2) You have not remarried. (3) You have a qualifying child who lived with you all year and you maintained the household. (4) You could have filed MFJ in the year of spouse’s death. Qualifying child requirement. A child, stepchild, or foster child who is a qualifying child of yours under §152(c). Must live with you the entire tax year (not just more than half). You must pay more than half the cost of keeping up the home. What QW status provides. Uses MFJ tax brackets and $30,000 standard deduction. Same as MFJ for tax computation purposes. Doesn’t allow joint filing (you file your own return as QW), but treats you tax-wise like MFJ. Years 1, 2, 3 post-death timeline. Year of death (2026): MFJ if you choose (recommended). Year 1 after death (2027): QW status if qualifying child. Or single/HoH if no qualifying child. Year 2 after death (2028): QW status if qualifying child still qualifies. Or single/HoH. Year 3 after death (2029): No longer QW. File as single or HoH (HoH if you have a qualifying child still living with you). Without qualifying child. If you don’t have a qualifying child (or yours has moved out, married, etc.), you file as single starting in 2027. Single brackets and $15,000 standard deduction. Significant tax increase vs MFJ in 2026. Remarriage. If you remarry, your filing status follows the new marriage (MFJ with new spouse, or MFS, or whatever applies). QW status doesn’t continue if you remarry. Income items year of death. Combine your income for the full year + husband’s income through date of death. All on the one MFJ return. IRD considerations. Husband’s IRD items (unpaid wages, IRA balance, etc.) are reported on the estate’s Form 1041 when received post-death, NOT on the joint 1040. If you inherited his IRA and roll it to your own IRA, the rollover isn’t immediate income; future distributions from the IRA are your income. Spousal IRA rollover vs inherited IRA. As surviving spouse, you have the most options for inherited IRA: (1) Spousal rollover — treat as your own IRA; RMDs based on your age. (2) Inherited IRA stretch — under SECURE Act, EDBs (eligible designated beneficiaries) including surviving spouses get to stretch over their life expectancy. (3) 10-year payout — if preferred. Spousal rollover is typically the most favorable. Estate planning beneficiary update. Update wills, beneficiary designations on retirement accounts and life insurance (if husband was a beneficiary), and any other documents. Consider whether to retain your existing estate plan or update it for changed circumstances. Social Security claiming. As widow(er), you can claim Social Security benefits based on (a) your own work record, (b) your husband’s record (survivor benefits — 100% of his PIA at full retirement age), or (c) some combination. If you’re approaching retirement age, get a SS planning consultation to improve the claiming strategy. Medicare and health insurance. Your Medicare coverage continues unaffected by husband’s death. If you were on his employer health plan, you have COBRA rights (typically 36 months for surviving spouses) or ACA Marketplace options. Tax planning for year of death and beyond. (1) Year of death: MFJ filing. Use all of husband’s deductions and credits. (2) Years 1-2: QW status if qualifying. Preserves MFJ-equivalent tax treatment. (3) Year 3+: single or HoH. Plan for tax increase. (4) Consider Roth conversions in lower-bracket years. (5) Review estate plan and beneficiary designations. Additional practical advice. Engage professionals early — CPA, attorney, appraiser. The cost of doing it right ($5K-$15K typically for a moderate estate) is far less than the cost of mistakes ($30K-$200K+ in unnecessary taxes for common errors). Keep beneficiaries informed throughout the process. Document every decision and election in writing. Maintain the estate accounting separately from your personal records. Don’t rush distributions before tax matters are resolved. The IRS has 3 years to audit (longer for fraud or substantial omission); maintain reserves for potential adjustments. Common executor mistakes to avoid. Distributing assets too early before all taxes are paid (personal liability). Missing the §213(c) medical expense election deadline. Failing to file Form 706 portability election (loses DSUE). Using decedent’s basis instead of stepped-up FMV. Missing IRD items. Incorrect filing status on final 1040. Not getting court-certified executor papers. Missing state estate tax filing deadlines.
