2026 Standard Deduction: All Filing Statuses Plus the 65+ and Blind Add-Ons

For 2026 the standard deduction for married filing jointly is $32,200. That is the base amount available to any couple who files jointly, regardless of age, before any add-ons. The $32,200 amount applies to MFJ taxpayers and to qualifying surviving spouse filers. It does not apply to married filing separately, which uses the single amount of $16,100 per spouse. The figure is set by the IRS in Revenue Procedure 2025-XX, the annual inflation-adjustment document.

The $32,200 amount is exactly twice the single standard deduction of $16,100. That parity is intentional under the post-TCJA structure: the law is designed so that a couple where one spouse earns all the income gets the same standard deduction as two single people filing separately. It does not always work out that way once you layer in brackets and credits, but the standard deduction itself is parity-by-design.

Exception: if either spouse turns 65 by January 1, 2027, that spouse adds $1,650 to the standard deduction. If both spouses are 65 or older, the deduction becomes $32,200 plus $1,650 plus $1,650, total $35,500. Add another $1,650 per spouse who is also legally blind. A couple where both spouses are 65 and both are blind gets a total standard deduction of $38,800. The add-ons stack and they apply per qualifying spouse.

Common mistake one: forgetting that the age cutoff for 2026 is based on whether you reach age 65 by January 1, 2027. So if a spouse’s 65th birthday is January 1, 2027, that spouse counts as 65 for the 2026 tax year. The one-day quirk is in IRS Publication 17 and consistent with how the IRS handles age tests across the code. Always check birthdays around year-end carefully. We see returns filed with the wrong add-on regularly.

Common mistake two: a spouse with significant disability or vision loss but who has not formally qualified as blind for tax purposes. The IRS definition is specific: not better than 20/200 vision in the better eye with corrective lenses, or a field of vision restricted to 20 degrees or less. Mild low vision does not qualify. You need a written statement from a qualified eye doctor (ophthalmologist or registered optometrist) on file. The statement is not attached to the return; it is kept with your records in case of audit.

Dollar example: couple with $200,000 of wage income, both spouses 64 years old. Standard deduction: $32,200. Taxable income: $167,800. Federal tax using 2026 MFJ brackets: $25,628. Now imagine the same couple but one spouse turned 65 mid-year. Standard deduction: $33,850. Taxable income: $166,150. Federal tax: $25,265. The age add-on saved them $363 in this single year. Over 20 to 30 years of retirement, that add-on is meaningful money.

Documentation: the standard deduction needs no supporting documentation beyond the filing status and the age and blindness add-ons. You check the boxes on Form 1040 indicating your status and any add-on conditions, and the standard deduction flows automatically. Tax software handles this. What you should keep is the eye doctor’s statement (for blindness), Social Security or birth certificate evidence (for age), and a copy of the standard deduction amount you used in case you ever need to amend.

Audit considerations: the standard deduction itself is essentially never audited because it is determined by filing status. What the IRS does check is whether you actually qualify for the filing status you claimed. Joint filers who file using each other’s Social Security numbers and addresses; surviving spouses who claim that status outside the two-year window; couples who file MFJ while living apart for non-temporary reasons; all of those can draw attention. The filing status determines the deduction, so getting the status right is what matters.

Where Reed Corp adds value is in the broader ‘should we itemize’ question that the joint standard deduction raises. The new $40,000 SALT cap means many of our New York and California clients should now itemize even with the higher MFJ standard deduction. We run the comparison every year for clients near the crossover. We also track over multiple years because itemizing one year and standardizing the next is legitimate and common; the right answer changes with property tax payments, charitable bunching strategies, and medical expense timing. The standard deduction is the floor; itemizing is the option that sometimes beats it.

Special rule for dependents: if you can be claimed as a dependent on someone else’s tax return, your standard deduction is limited. For 2026 a dependent’s standard deduction is the greater of $1,400 or your earned income plus $450, but not to exceed the regular standard deduction for your filing status. This rule mostly affects college students and teenagers with summer jobs. A college freshman with $5,000 of summer job income and no other income gets a standard deduction of $5,450 ($5,000 earned + $450), reducing their taxable income to nearly zero. The dependent rule is in Publication 501.

The MFJ standard deduction also matters indirectly for households claiming credits. The Child Tax Credit is reduced by $50 per $1,000 of MAGI over the threshold ($400,000 for MFJ). Higher standard deduction means lower taxable income for bracket purposes but does not change MAGI. So the standard deduction increase helps with tax brackets but not with credit phaseouts. Households at the edge of credit phaseouts should not assume the standard deduction increase keeps their credits intact; they need to check MAGI specifically.

One final point on the MFJ standard deduction: it interacts with state tax returns in ways that vary by state. Most states allow a state-specific standard deduction that does not match the federal amount. New York’s MFJ standard deduction for 2026 is around $16,050, less than half the federal. California uses about $11,080. New Jersey has no standard deduction at all (you take a personal exemption instead). So the federal standard deduction decision and the state standard deduction decision are separate. Some states require you to use the same method federal-itemize-state-itemize or federal-standard-state-standard, but most allow you to choose independently. That sometimes flips the optimal answer: itemize federal, take state standard, or vice versa.

The 2026 age 65+ add-on is $1,650 if you are married (filing MFJ, MFS, or as a surviving spouse) and $2,050 if you are single or filing as head of household. The amounts apply per qualifying spouse. So a married couple with both spouses age 65 or older gets $1,650 plus $1,650, total $3,300 of age add-on, on top of their $32,200 MFJ base. Their total standard deduction: $35,500. A single 65+ filer gets $16,100 plus $2,050, total $18,150.

Important new piece for 2026 that did not exist before 2025: OBBBA created a temporary $6,000 senior bonus deduction available for tax years 2025 through 2028. It stacks on top of the regular age add-on, with no separate qualifying test beyond turning 65. The bonus phases out at higher incomes: the full bonus applies at modified AGI up to $75,000 single / $150,000 MFJ, then drops by 6 cents per dollar of MAGI above that, reaching zero at $175,000 single / $250,000 MFJ. So a single 65+ retiree with AGI well below $75,000 gets a 2026 standard deduction of $16,100 base + $2,050 age + $6,000 OBBBA bonus = $24,150. That is a real shift from prior years and one of the biggest senior-targeted federal tax changes since 2017. The bonus disappears after 2028 unless Congress extends it.

The cutoff is whether you turn 65 by January 1 of the year following the tax year. For 2026 returns, that means whether you reach age 65 on or before January 1, 2027. A taxpayer born on January 1, 1962 turns 65 on January 1, 2027 and qualifies for the 2026 add-on. A taxpayer born on January 2, 1962 turns 65 on January 2, 2027 and has to wait until 2027 to claim the add-on. The one-day cutoff is consistent across the tax code’s age-65 tests.

Exception for the higher single rate: the $2,050 (rather than $1,650) applies only if you are single or filing as head of household. Married filers, including surviving spouses claiming the qualifying surviving spouse status, use the $1,650 add-on per qualifying spouse. So a single 70-year-old gets $2,050 of age add-on; a married 70-year-old whose spouse is 60 gets $1,650 of age add-on. The single rate is higher because the single base deduction is lower; the policy is roughly to bring them to similar dollar amounts.

Common mistake one: assuming both spouses get the larger single-rate add-on. They do not. Even if both spouses are 65 or older, the per-spouse add-on for MFJ is $1,650 each, totaling $3,300. Many tax software products handle this correctly, but we have seen self-prepared returns add $2,050 per spouse, inflating the standard deduction by $800. Eventually the IRS notices because the math does not match the filing status.

Common mistake two: counting the blindness add-on as part of the age add-on rather than as a separate stack. They are separate. A single 67-year-old who is also blind gets $16,100 base plus $2,050 age plus $2,050 blindness, total $20,200. A married 67-year-old who is also blind gets the marriage rate add-ons of $1,650 plus $1,650, on top of the joint base. The two add-ons stack independently.

Dollar example: single retiree, age 68, receiving $40,000 from a pension and $25,000 from Social Security. Roughly $21,250 of Social Security is taxable (85 percent). Gross taxable income before deductions: $61,250. Standard deduction: $18,150 ($16,100 base plus $2,050 age add-on). Taxable income: $43,100. Federal tax using 2026 single brackets: $4,924. Without the age add-on, taxable income would be $45,150 and federal tax would be $5,375. The age add-on saved her $451 of federal tax for 2026.

Documentation: you do not attach proof of age to your return. The IRS verifies through Social Security records when needed. Keep a copy of your driver’s license or passport in your tax file in case of an audit, but the standard deduction calculation itself does not require attaching documents. Tax software typically asks for your date of birth and applies the add-on automatically.

Audit considerations: the IRS rarely audits age claims because they can verify through SSA records. What sometimes happens is a software glitch or self-prep error where the add-on is calculated wrong. The most common error we see on amended returns is taxpayers who missed the age add-on entirely on their original return because the software did not ask the right question. If you are over 65 and used self-prep software, double-check that your standard deduction includes the add-on. The difference is on Form 1040 line 12, and the IRS has the higher amount visible to them in their system.

Where Reed Corp adds value for retirees is in the broader income strategy that the age add-on plays a small part in. The standard deduction increase combined with the brackets, the Social Security taxable portion calculation, and Required Minimum Distribution timing all interact. A 73-year-old client with a $2 million traditional IRA, $40,000 of Social Security, and a paid-off home has many decisions to make about RMD timing, Roth conversion strategy, charitable Qualified Charitable Distribution use, and capital gains harvesting. The age add-on is one tool among many. We model the full picture annually so the small dollars add up across the strategy.

Worth noting: the age add-on does not phase out at any income level. A single 70-year-old earning $500,000 still gets the $2,050 add-on, same as a 70-year-old earning $20,000. The benefit is constant across income levels but the dollar value varies because it depends on the marginal bracket. At the 37 percent bracket the $2,050 add-on saves $759 of federal tax; at the 10 percent bracket it saves $205. Higher-income elderly taxpayers get more dollar benefit from the same add-on, which is the opposite of most means-tested benefits.

The age threshold also unlocks a separate planning tool: Qualified Charitable Distributions from IRAs. Once you reach age 70 1/2 you can transfer up to $108,000 (for 2026) directly from your IRA to a qualified charity. The QCD counts toward your Required Minimum Distribution but is excluded from taxable income, which is more valuable than taking the distribution and deducting the gift. The QCD effectively gives you a charitable deduction without itemizing. Many of our retired clients with charitable intent take the standard deduction and use QCDs for their giving; the combined strategy is cleaner than itemizing on the return.

Finally, one more wrinkle on the age add-on worth mentioning: the half-year rule for 65 has occasional edge cases. The Internal Revenue Code says you are treated as 65 on the day before your 65th birthday. So a taxpayer born on January 2, 1962 is treated as turning 65 on January 1, 2027, which means they qualify for the 2026 age add-on. The IRS Publication 17 walks through the example explicitly. We have helped clients claim the 2026 add-on whose 65th birthday is technically in 2027 because of this day-before rule. The dollar value is meaningful and the rule is in our favor.

The 2026 itemize-versus-standard decision is mechanical: add up your itemizable deductions and compare to your standard deduction. If itemized is higher, itemize. If standard is higher, take standard. For 2026 the standard amount is $32,200 MFJ, $16,100 single, $24,150 HoH. The itemizable deductions are state and local taxes (capped at $40,000 under the temporary OBBBA cap), mortgage interest on acquisition debt up to the $750,000 limit, charitable contributions, and medical expenses over 7.5 percent of AGI, plus a few smaller categories.

The single biggest variable is state and local taxes. For taxpayers in high-tax states, the new $40,000 SALT cap (for tax years 2025 through 2029 only) opens the door to itemizing for many households who could not under the prior $10,000 cap. A New York City couple with $20,000 of property tax and $15,000 of state income tax now has $35,000 of deductible SALT, up from $10,000. That alone is more than the entire single standard deduction.

Exception: you have no choice if your spouse itemizes. If you file MFS and your spouse itemizes, you must also itemize, even if it gives you a smaller deduction. The opposite is also true: if your spouse takes the standard deduction, you can either also take standard or itemize, but you cannot have your spouse switch later. This rule sometimes traps couples filing MFS for income-driven student loan repayment reasons; both spouses get stuck with whichever method works for one of them.

Common mistake one: forgetting that mortgage interest is only deductible on acquisition debt up to $750,000 for loans originated after December 15, 2017. Older mortgages have a $1,000,000 cap. Home equity loan interest is only deductible if used to buy, build, or substantially improve the home that secures the loan. We see clients trying to deduct HELOC interest for car purchases or college tuition. Not allowed.

Common mistake two: charitable contribution cash gifts have a 60 percent of AGI limit; gifts of appreciated stock have a 30 percent of AGI limit; gifts to private foundations have a 30 percent limit. Donor-advised fund contributions count as gifts to public charities (60 percent). Carryforwards apply to amounts above the limit, for up to five years. People who do major one-time gifts often bunch them into one year to itemize that year, then take the standard deduction in subsequent years. That bunching strategy works mathematically when the gifts are large enough.

Dollar example one: New York City couple, MFJ, with $300,000 of wages, $18,000 property tax, $13,000 New York state income tax, $4,500 New York City income tax, $8,000 charitable contributions, $12,000 mortgage interest on a $600,000 mortgage. SALT total: $35,500 (under the $40,000 cap). Plus mortgage $12,000. Plus charity $8,000. Itemized total: $55,500. Standard deduction: $32,200. Itemize. The extra $23,300 of deduction is worth $5,592 of federal tax at the 24 percent bracket.

Dollar example two: same couple, but living in Florida with no state income tax. Property tax: $8,000. No state income tax. SALT total: $8,000. Mortgage: $12,000. Charity: $8,000. Itemized total: $28,000. Standard deduction: $32,200. Take standard. The Florida couple gets a better outcome from the standard deduction by $4,200 of deduction, worth about $1,008 of federal tax at the 24 percent bracket. State location matters enormously for the itemize decision.

Documentation matters more when you itemize. Receipts for all charitable contributions of $250 or more (Section 170(f)(8) requires a contemporaneous written acknowledgment from the charity). Records of state income tax paid (state returns, W-2 box 17, estimated tax payment records). Property tax bills paid in the calendar year. Form 1098 from the mortgage lender showing deductible interest. Medical expense receipts if you are over the 7.5 percent floor. The audit risk increases with itemizing because there is more to verify.

Audit considerations: itemized returns have a slightly higher audit rate than standard-deduction returns, mostly because the IRS has more lines to check. Charitable contributions over $5,000 require qualified appraisals (for non-cash gifts) and Form 8283 disclosure. Casualty losses (rare since TCJA limited them to federally declared disasters) draw extra scrutiny when claimed. The basic SALT, mortgage interest, and small charitable contribution claims rarely draw attention if the numbers are reasonable.

Where Reed Corp adds value is in running the comparison annually with the correct data and looking ahead. Itemize-versus-standard is not always a one-year decision; the bunching strategy of two-year-cycles can save significant tax over time. We also model the SALT cap interaction with state pass-through entity tax elections (PTET) for self-employed clients, which can move state tax deductibility above the SALT cap entirely. That is a planning conversation worth having, not a tax-time check-the-box question.

Worth noting on bunching: the strategy works mathematically only if the bunched year’s itemized total exceeds the standard deduction by enough to justify the lost standard deduction in the off year. A couple who bunches $25,000 of charitable giving into one year while paying $15,000 of SALT (under cap) gets $40,000 of itemized deductions versus a $32,200 standard deduction. The bunching benefit: $7,800 of extra deduction in the bunch year. In the off year they take the $32,200 standard. Over two years they get $72,200 of deduction versus $64,400 if they had given evenly and standardized both years. The math is real but requires discipline.

A donor-advised fund (DAF) is the tool that makes bunching practical. You can fund a DAF in the bunch year, taking the deduction immediately, and then make grants from the DAF to charities over many years. This decouples the timing of the tax deduction from the timing of the actual charitable giving to operating charities. Fidelity Charitable, Schwab Charitable, Vanguard Charitable, and many community foundations administer DAFs. Minimum contributions are typically $5,000 to $25,000 depending on the sponsor. We have set up DAFs for many clients in connection with bunching strategy work.

A final practical tip on the itemize decision: run the math both ways before filing. Tax software does this automatically and shows you which method produces the lower tax. If the numbers are close (within $500 of total tax), itemize anyway because itemizing locks in the deductions in case of an amended return or audit, and the small dollars of extra tax saved in standardizing are rarely worth losing the itemized basis. The rule we use is that any year with deductible state taxes above $30,000 likely itemizes; any year below $20,000 of SALT likely standardizes. Between $20,000 and $30,000 is the gray zone where the math goes either way depending on other items.

Yes, and you get an additional standard deduction on top of the base amount. For 2026 the blindness add-on is $1,650 if you are married (filing MFJ, MFS, or as a surviving spouse) or $2,050 if you are single or filing as head of household. The add-on applies per qualifying spouse. So a single blind filer gets $16,100 base plus $2,050 add-on, total $18,150. A married couple where both spouses are blind gets $32,200 plus $1,650 plus $1,650, total $35,500.

The IRS definition of blind for the deduction is specific. You qualify if your central visual acuity does not exceed 20/200 in the better eye with corrective lenses, or if your visual field is limited to 20 degrees or less. The legal standard tracks the Social Security Administration’s definition of statutory blindness. Partial sight, low vision, or color blindness does not qualify unless it meets the 20/200 or 20-degree thresholds. The standard is essentially functional blindness, not any vision impairment.

Exception: if you are blind only at the end of the tax year (say, vision deteriorated mid-year and now meets the threshold), you can claim the add-on for that tax year as long as the qualifying condition exists on December 31. Conversely, if your vision improves to better than 20/200 during the year, you lose the add-on for that year. The condition is determined as of the close of the tax year. This matters most for taxpayers with deteriorating vision conditions on the borderline.

Common mistake one: not having a written certifying statement from a qualified eye doctor. You need a statement from an ophthalmologist, optometrist, or other qualified eye doctor confirming the visual acuity or visual field limitation. The statement does not get attached to the tax return, but it must be in your records. The IRS asks for it during a small percentage of audits, and not having it means losing the deduction if the audit catches you.

Common mistake two: assuming a Social Security disability award based on blindness is sufficient documentation. It usually is, but only if the SSA’s award was based on the specific blindness standard rather than general disability. Veteran’s disability awards for vision are similar; they sometimes match the IRS standard, sometimes do not. The safest course is a current eye doctor’s statement that uses language matching the IRS standard. We have helped clients reconstruct documentation after the fact, but it is much easier to get the statement at the time of diagnosis.

Dollar example: married couple, both spouses age 60, one spouse is blind. Standard deduction: $32,200 base plus $1,650 blindness add-on for the blind spouse. Total: $33,850. If they were a MFJ couple with $150,000 of wage income, taxable income after the standard deduction is $116,150. Federal tax under 2026 MFJ brackets: $14,209. Without the blindness add-on, taxable income would be $117,800 and federal tax would be $14,572. The add-on saves them $363 of federal tax for the year.

Stacking with age: a 67-year-old blind single filer gets $16,100 base, $2,050 age add-on, and $2,050 blindness add-on, total $20,200. A married couple where both spouses are 67 and one is blind gets $32,200 base plus $1,650 plus $1,650 plus $1,650, total $37,150. The stack matters most for elderly taxpayers with vision loss because the combined add-ons can effectively double the base standard deduction.

Documentation: keep a copy of the eye doctor’s written certification with your tax records permanently. The IRS does not have a routine way to verify blindness like they do age (which they can check through SSA). If they audit and ask for proof, the eye doctor’s statement is what you produce. Save it digitally so you do not lose the paper copy. We recommend redating the statement every five years or so if the condition is stable, since some older statements get questioned during audits if they predate the tax year by many decades.

Audit considerations: the IRS does occasionally check the blindness add-on, but usually only when the rest of the return raises questions. A standalone audit just to verify blindness is rare; an audit triggered by other items that then includes a check of the blindness claim is more common. If you cannot produce the certifying statement, the add-on is disallowed and interest accrues from the original due date. That can be a several-hundred-dollar reversal, which is unpleasant but not financially catastrophic.

Where Reed Corp adds value for taxpayers with vision impairments is in the broader picture beyond the standard deduction. The Earned Income Tax Credit has different rules for blind filers in some circumstances. Some state tax codes also have blindness deductions or exemptions that we model. Disability-related work expenses can be deductible as impairment-related work expenses, which is a separate category from medical expenses. The standard deduction add-on is the most common piece, but it is rarely the only one. We make sure every available benefit is claimed correctly.

Worth noting: ABLE accounts (Achieving a Better Life Experience accounts) under IRC Section 529A allow disabled individuals to save money in tax-advantaged accounts without losing eligibility for means-tested benefits. ABLE accounts are not directly related to the standard deduction blindness add-on, but they are part of the broader tax-and-benefits landscape for individuals with qualifying disabilities. Contributions to ABLE accounts may also qualify for the Saver’s Credit if income is low enough. These items work together rather than in isolation.

Another adjacent item: the blindness add-on is one of the few tax benefits that does not require itemizing to access. You can take the standard deduction plus the blindness add-on plus the age add-on, and you still get to deduct medical expenses on Schedule A separately if you itemize (medical expenses are not part of the standard deduction). But if you take the standard deduction, you do not get to also deduct medical expenses; the standard deduction is thorough of everything Schedule A would offer. People sometimes assume the blindness add-on is on top of medical expense deductions. It is not; it is on top of the basic standard deduction only.

The 2026 standard deduction amounts increased by about 2.2 percent across the board from 2025, in line with the Chained CPI-U inflation adjustment that the IRS uses each year. Specifically, MFJ moved from $31,500 to $32,200 (a $700 increase), single and MFS moved from $15,750 to $16,100 (a $350 increase), and head of household moved from $23,625 to $24,150 (a $525 increase). The 65+ and blindness add-ons moved from $1,600 to $1,650 ($2,000 to $2,050 if unmarried).

The dollar value of those increases varies by bracket. At the 12 percent bracket, the $700 MFJ increase saves $84 of federal tax. At the 22 percent bracket, $154. At the 24 percent bracket, $168. At the 32 percent bracket, $224. At the 35 percent bracket, $245. At the 37 percent bracket, $259. These are not life-changing numbers. They are the inflation-adjustment baseline that keeps the tax system from creeping over time.

Exception: the increases are slightly smaller than the previous year’s increases because Chained CPI-U has been cooler than headline CPI for the past two years. From 2024 to 2025 the MFJ standard deduction went from $29,200 to $31,500, a $2,300 increase (7.9 percent). That larger jump reflected the high-inflation period of 2022-2023. From 2025 to 2026 the increase shrank to $700 (2.2 percent) because the trailing twelve-month inflation has cooled.

Common mistake: assuming inflation indexing fully offsets wage growth. It does not. Wages have grown faster than C-CPI-U for the past several years. A worker whose wage grew 4 percent year over year while the standard deduction grew 2.2 percent will see slightly more of their income subject to tax. That gap, slow as it is, is what economists call bracket creep. OBBBA made the larger standard deduction permanent and stopped the snap-back creep, but the slow drift continues.

Worked comparison: MFJ couple with $200,000 of wage income, both spouses under 65, no itemizing. 2025: standard deduction $31,500. Taxable income $168,500. Federal tax under 2025 brackets: $26,067. 2026: standard deduction $32,200. Taxable income $167,800. Federal tax under 2026 brackets: $25,628. Year-over-year savings on the same income: $439. About $84 of that is from the standard deduction increase, the rest is from the bracket widening. The numbers compound when you carry the analysis across both effects.

Worked comparison at higher income: single filer with $500,000 of taxable income before the deduction. 2025: standard deduction $15,750. Taxable income $484,250. Federal tax: $146,250. 2026: standard deduction $16,100. Taxable income $483,900. Federal tax: $145,189. Savings: $1,061 year over year on the same gross income. About $112 from the standard deduction (at the 32 percent bracket), the rest from bracket widening. The dollars scale with income.

Documentation of year-over-year comparisons is rarely needed for a return, but it matters for planning. Save the prior-year return next to the current-year return in a way that lets you compare effective rates, taxable income, and the components of the bill. Most tax software does this automatically with a year-over-year comparison sheet in the print package. Tax preparers often include it in client the work; we always do.

Audit considerations: comparing 2025 and 2026 standard deductions is not an audit issue. What can become an audit issue is changing your filing status between years inappropriately. A taxpayer who filed single in 2025 and claims head of household in 2026 needs the qualifying conditions for HoH actually present in 2026; the standard deduction difference of $8,050 ($16,100 vs $24,150) makes HoH attractive enough to misclassify. The IRS audits HoH claims more often than they audit single or MFJ.

Where Reed Corp adds value on year-over-year tracking is in the trend analysis we do across multiple years for clients. A retired client who started taking Social Security in 2024 has an income picture that shifts each year as they layer in pensions, IRA distributions, and Roth conversions. The standard deduction trends with inflation, but their income may be growing faster or slower than that. We project out three to five years to keep the standard deduction decision aligned with their broader retirement income plan. The standard deduction alone is not actionable; in context with income trends, it is one of the inputs we use to time conversions, distributions, and gifts.

Tracking the year-over-year change also helps with quarterly estimated tax planning. If your 2025 effective rate was 17.5 percent and your projected 2026 effective rate is 17.2 percent on similar income, your quarterly estimated payments should adjust slightly downward. Most software just rolls forward the prior year’s quarterly amounts, which can leave you over-paid (small refund at filing time) or under-paid (small underpayment penalty). Tightening estimated payments to match the projected liability is worth doing if you have variable income or if your 2026 picture looks meaningfully different from 2025.

Last thing on year-over-year comparisons: the standard deduction for dependents is calculated differently from the regular standard deduction and follows its own inflation track. For 2026 a dependent’s standard deduction is the greater of $1,400 or earned income plus $450, capped at the regular standard deduction for their filing status. From 2025 ($1,350 minimum, +$450 over earned income) the numbers moved up only modestly. Parents with college-age children working part-time should know the dependent rules separately because they often determine whether a child needs to file their own return at all. Below the dependent standard deduction, a child with only earned income owes no federal income tax.

One last point on year-over-year comparison: the inflation-adjustment trend is also useful when you are deciding whether to accelerate or defer income across calendar years. If 2027 brackets and standard deductions widen another 2 to 3 percent, deferring a discretionary $50,000 of income from December 2026 to January 2027 saves you roughly $150 to $300 of federal tax just from the inflation adjustment alone. That is on top of any bracket-crossing effect. For self-employed clients with billing flexibility, this year-end timing question is real money. We do this analysis in early November for clients who control their year-end billing.

And one more bracket-creep note: the C-CPI-U adjustment compounds. A 2 percent annual adjustment for 10 years yields about 22 percent of cumulative widening. Over a typical career or retirement horizon, this slow grind matters. Plan so.
