Charitable Remainder Trust Tax Benefits in 2026: A Practical Guide for HNW Clients
The §664 framework and the basic mechanics
Section 664 of the Internal Revenue Code defines two types of charitable remainder trusts: the Charitable Remainder Annuity Trust (CRAT) under §664(d)(1) and the Charitable Remainder Unitrust (CRUT) under §664(d)(2). Both are irrevocable trusts that pay a stream of income to non-charitable beneficiaries for a term and then distribute the remaining assets to charity. The defining difference is the payment formula: a CRAT pays a fixed dollar amount each year, while a CRUT pays a fixed percentage of the trust’s annual value. Both forms qualify for charitable remainder trust tax benefits including the upfront income tax deduction and the tax-exempt status of the trust itself.
The trust must satisfy strict requirements to qualify under §664. The payout rate must be at least 5% and no more than 50% of the initial fair market value (for CRATs) or the annual revalued fair market value (for CRUTs). The charitable remainder interest must be at least 10% of the initial fair market value at inception. The term of the trust must be either a term of years (not exceeding 20 years) or the life or lives of one or more individuals living at the trust’s creation. The charity must be a qualified §501(c)(3) organization or a public charity, and the trust document must specify the beneficiary charity or give the donor (or another party) the power to designate.
Once formed and funded, the trust operates as a tax-exempt entity. It can sell appreciated assets without recognizing gain. It can invest the proceeds across whatever asset classes the trust document allows, generating income from interest, dividends, and capital appreciation. The trust pays the required annual distribution to the non-charitable beneficiaries (the donor and any other named individuals) and accumulates the rest. The income recipient pays tax on the distributions based on the four-tier characterization rules in §664(b), which we cover in detail later in this guide.
Charitable Remainder Trust Tax Benefits: CRAT vs CRUT: which form to choose
The choice between CRAT and CRUT comes down to whether the donor wants stable annual income or income that grows with the trust’s investment performance. A CRAT pays the same dollar amount every year regardless of the trust’s investment performance. If the donor puts $5M into a CRAT with a 5% payout rate, the trust pays $250,000 per year forever. The amount does not change. The CRAT provides predictability but offers no inflation protection and no upside if the trust performs well. The trust may also run out of money before the term ends if the investment returns fall short of the payout rate, which collapses the structure.
A CRUT pays a fixed percentage of the trust’s annual revalued assets. A $5M CRUT with a 5% payout rate pays $250,000 in year one but the payment changes each year based on the trust’s value. If the trust grows to $7M, the payment increases to $350,000. If the trust drops to $3M, the payment decreases to $150,000. The CRUT provides inflation protection and upside but creates payment volatility. It cannot run out of money before the term ends because the payment automatically scales down with the trust’s value. The CRUT is the more popular form for most HNW clients precisely because of these features.
There are also specialized variations. The Net Income with Make-Up CRUT (NIMCRUT) pays the lesser of the stated percentage or the trust’s actual income, with provisions to make up shortfalls in later years when income permits. The Flip-CRUT starts as a NIMCRUT and converts to a regular CRUT upon a triggering event (typically the sale of a hard-to-value asset like real estate or closely-held stock). These structures are useful when the donor expects to fund the trust with non-income-producing or illiquid assets and wants to avoid the trust having to distribute principal in the early years before the assets are sold. The structure choice is fact-specific and should be coordinated with the donor’s investment plan.
The upfront charitable deduction calculation
The charitable remainder trust tax benefits begin with the upfront income tax charitable deduction equal to the present value of the charitable remainder interest. The calculation uses the §7520 rate (a monthly published rate that approximates intermediate-term Treasury yields) and standard actuarial tables to compute what portion of the trust’s initial value will eventually go to charity, in present value terms. The higher the §7520 rate, the higher the present value of the remainder interest, and the larger the upfront deduction.
Concrete example. A 65-year-old donor contributes $5M of appreciated stock to a CRUT with a 5% payout rate, with the donor as the sole income beneficiary for life. The §7520 rate is 5.0% in the month of contribution. The IRS actuarial tables compute the present value of the charitable remainder interest at approximately $2.1M, or 42% of the initial contribution. The donor’s charitable deduction in the year of contribution is $2.1M. The deduction is limited to 30% of AGI for appreciated property contributions to public charity under §170(b)(1)(C), with a 5-year carryforward for unused amounts.
The deduction calculation favors older donors (because the actuarial life expectancy is shorter, the remainder is closer in time and worth more in present value), higher §7520 rates (because the discount rate makes future amounts worth more in present value), and higher charitable payout rates that reduce the income payments. A CRUT with a 5% payout produces a higher charitable deduction than the same CRUT with a 7% payout, all else equal. The trade-off is income payments: lower payouts produce larger upfront deductions but smaller income streams. The optimal payout rate depends on the donor’s income needs and tax characteristics.
Tax-exempt sale and gain deferral inside the trust
The single largest of the charitable remainder trust tax benefits for most HNW donors is the tax-exempt sale of appreciated assets inside the trust. The donor contributes appreciated stock, real estate, business interest, or other assets to the trust. The trust then sells those assets without recognizing capital gain because of its §664 status. The trust converts the appreciated assets into a diversified investment portfolio (typically stocks, bonds, alternatives) without ever triggering capital gains tax. The donor effectively defers the capital gain that would have been recognized on a direct sale.
Concrete example. Donor has $4M of cost basis in stock now worth $10M. Selling directly produces $6M of long-term capital gain taxed at roughly 32.7% combined for a NYC HNW investor, equals $1.96M of tax. Contributing the same stock to a CRT eliminates the $6M of gain inside the trust (because the trust is tax-exempt for §664 purposes). The trust sells the stock for $10M and invests the full $10M, rather than $8M after tax. The donor has $2M more invested earning returns over the life of the trust. The income payments back to the donor over decades are taxed under the four-tier rules, but the donor never pays tax on the original $6M of gain directly.
The trust’s ongoing investment income (interest, dividends, capital gains on the new portfolio) is not taxed inside the trust either. Section 664 provides full tax exemption for the trust’s investment activities. The trust’s income only becomes taxable to anyone when it is distributed to the non-charitable beneficiaries, and even then it is taxed at the donor’s individual rates under the §664(b) tier system rather than at trust rates. The donor effectively gets the benefit of decades of tax-deferred compounding inside the trust on the contributed amounts plus the original gain that was avoided.
The four-tier income characterization under §664(b)
Distributions from a charitable remainder trust to the non-charitable beneficiaries are characterized in four tiers under §664(b), in this order: ordinary income, capital gain, tax-exempt income, return of corpus. Each year’s distribution comes out of the highest tier first that has accumulated income available. Once a tier is exhausted, the next lower tier provides the characterization for additional distributions. This tier ordering produces a worst-tier-first effect: the donor’s income payments are characterized as the highest-tax form of income that the trust has earned, until that bucket is empty.
Tier one is ordinary income, including interest, dividends, rental income (net of depreciation), royalties, and any other income that would be ordinary if earned directly by the beneficiary. The trust accumulates ordinary income from its investment portfolio (mostly dividends and interest from bonds). Distributions are characterized as ordinary income until the trust’s accumulated ordinary income is exhausted. For a high-income donor in NYC, ordinary income is taxed at roughly 53.4% combined marginal rate. This is the worst-case characterization for distributions from a CRT.
Tier two is capital gain, characterized further as long-term or short-term based on the holding period inside the trust. The trust’s accumulated capital gains from selling the originally contributed appreciated assets and from any subsequent portfolio rebalancing are reported here. Long-term capital gain is taxed at 20% federal plus 3.8% NIIT plus state and city, roughly 32.7% combined for NYC top bracket. Tier three is tax-exempt income (interest from municipal bonds held inside the trust). Tier four is return of corpus, not subject to tax. The four-tier ordering means the donor pays the highest applicable tax rate on each year’s distribution until the trust runs out of accumulated higher-tier income. Most CRTs reach the capital gain tier in years 2-10 and the corpus tier eventually as the contributed assets’ embedded gain works its way through the system.
Estate planning and the remainder to charity
The remainder to charity is the defining feature of the CRT and the source of both the upfront charitable deduction and the estate tax benefits. The remainder interest is included in the donor’s gross estate at the date-of-contribution value reduced by the income interest, but is then offset by an estate tax charitable deduction under §2055 for the full value of the remainder passing to charity. The net effect is zero estate inclusion for the charitable remainder, regardless of how much the trust has grown by the date of death. This is one of the more powerful estate-tax-elimination tools in the code, comparable in effect to outright lifetime gifts to charity.
Consider a donor age 70 who contributes $10M of appreciated stock to a CRUT with a 5% payout. Upfront charitable deduction: roughly $4.3M based on §7520 actuarial tables. The donor receives $500,000 of income payments in year one, scaling with trust value over time. The donor dies at age 88. The trust’s value at death is $14M. The full $14M passes to charity at that point. The estate tax exposure on that $14M is zero because of the §2055 estate tax charitable deduction. Without the CRT, the $10M would have been in the donor’s estate (potentially appreciated to $14M+ over 18 years), subject to estate tax at 40% above the exemption amount. The CRT eliminated potentially $5M+ of estate tax exposure on the trust’s eventual value.
The trade-off is that the donor’s heirs receive nothing from the CRT. The donor’s family loses the capital appreciation of the contributed assets to the extent it stays in the trust at the donor’s death. This is fundamental to CRT planning and the reason CRTs are not appropriate for clients who want their assets passing to family. Clients who want both lifetime income and family inheritance typically pair the CRT with a life insurance policy held in an irrevocable life insurance trust (ILIT), with premiums funded from the CRT income payments. The ILIT death benefit replaces the wealth that the CRT directs to charity. The combined structure produces lifetime income, family inheritance through the ILIT, and the charitable remainder to charity, all with substantial tax efficiencies along the way.
Common use cases and the right client profile
The classic CRT use case is a HNW client with a very low-basis appreciated asset (founder stock, inherited stock, real estate held for decades) who wants to diversify, generate lifetime income, and has genuine charitable intent. The asset is too expensive to sell directly because of the embedded gain. The CRT converts the asset to a diversified income stream without triggering the gain. The donor gets an upfront deduction, lifetime income, diversification, and the eventual charitable remainder. All of these are simultaneous benefits that no other single structure can produce.
Concrete client profile that fits well. Age 67, recently sold a business, has $8M of low-basis Microsoft stock from a 1990s-era founder grant, plus other diversified assets. Wants to reduce equity concentration, retire comfortably, and has been a regular donor to a university and a hospital throughout life. CRT funded with the Microsoft stock works perfectly: tax-exempt sale, $3M+ upfront deduction, $400,000 annual income for life, eventual $10M+ remainder to the donor’s choice of charities. The client gets out of the concentrated position cleanly while supporting causes she cares about and receiving meaningful retirement income.
Client profiles that do not fit. A client who wants the assets to go to family at death, not charity. A client whose primary goal is current tax deduction without giving up future control of the assets. A client with charitable intent but who prefers to give directly each year rather than commit to an irrevocable structure. A client who is too young (under 55) for the actuarial math to favor a CRT over alternatives. A client with significant other income who does not need the lifetime income stream. The CRT is a specialized tool that solves a specific problem. Forcing it into other situations produces suboptimal results.
Common mistakes and audit risk
The most common CRT mistake is incorrect actuarial calculations on the upfront deduction. The IRS provides published actuarial tables under §7520, and the deduction calculation must use those tables (or specialized software that implements them correctly). Hand calculations regularly produce errors. The IRS examines the deduction calculation on every CRT created above a meaningful threshold, and discrepancies produce reduced deductions plus accuracy-related penalties. We always use specialized CRT software (Number Cruncher, Steve Leimberg’s calculators) for the actuarial work and have the calculation reviewed independently before the deduction is claimed.
Failing to maintain qualification is another common issue. The CRT must satisfy ongoing requirements: pay the required distributions, maintain the 10% charitable remainder, not pay private benefit, file Form 5227 annually. Trust accounting failures can disqualify the trust retroactively, which converts the entire structure into a taxable trust and wipes out all the charitable remainder trust tax benefits. The trustee must understand the §664 rules and apply them consistently. Most CRTs are administered by professional corporate trustees or attorneys, which reduces this risk significantly. DIY CRTs run by family members or non-specialists are a recipe for disqualification.
Contributing the wrong type of asset is a third common error. Section 664 prohibits certain asset types from being contributed without triggering recognition. S-corporation stock generally cannot be held by a CRT because the trust is not an eligible S-corporation shareholder under §1361. Mortgaged real estate creates unrelated business income tax (UBIT) exposure inside the trust under §511. Partnership interests can create UBIT depending on the partnership’s activities. Inventory and self-created intangibles produce ordinary income treatment that bypasses the tier system. The asset selection at funding is critical, and contributing the wrong asset can collapse the structure.

Frequently Asked Questions
What are the main charitable remainder trust tax benefits compared to selling outright and donating cash?
The charitable remainder trust tax benefits compare favorably against the alternative of selling appreciated property outright and then donating cash, but the comparison depends on the donor’s specific situation. Selling outright produces capital gains tax in the year of sale at roughly 32.7% for a NYC HNW donor on the gain amount. The net after-tax proceeds are then available for either reinvestment or charitable gifting. The eventual charitable cash gift produces a deduction at 60% of AGI (the limit for cash gifts to public charity), which is more generous than the 30% AGI limit for appreciated property to public charity through a CRT. But the donor has paid capital gains tax on the entire gain that would have been deferred through the CRT, which is a significant cost.
Concrete numerical comparison. Donor has $10M of stock with $2M basis. Option A: sell outright and donate the after-tax proceeds. Capital gain: $8M at 32.7% = $2.6M tax. After-tax proceeds: $7.4M. If $4M is donated to charity, the cash charitable deduction is $4M against 60% AGI limit. Net charitable benefit: $4M to charity, after-tax retention: $3.4M, plus the tax savings on the $4M charitable deduction (at 47% marginal ordinary rate) = $1.88M tax savings. Total economics: $3.4M retained plus $1.88M tax savings minus $2.6M capital gains tax = net retained value of $2.68M plus the $4M charitable gift.
Option B: contribute the $10M of appreciated stock to a CRUT. No capital gains tax. Upfront charitable deduction equals the present value of the charitable remainder, roughly $4.3M for a 67-year-old donor with 5% payout. Charitable deduction at 30% AGI limit: $4.3M, saving roughly $2M in income tax. Income stream from the CRT over remaining life expectancy of 22 years: starting at $500,000/year and growing with trust performance, totaling perhaps $15M+ in nominal lifetime income (taxed under the four-tier rules at the donor’s rates). Eventual remainder to charity: approximately $14M (depending on trust performance and life expectancy).
The CRT path produces much more total charitable benefit ($14M remainder to charity versus $4M cash donation in Option A) plus dramatically more lifetime income to the donor. The donor’s tax savings from the upfront deduction are similar to Option A. The donor pays tax on the income stream over decades rather than the capital gains tax in year one. The total tax cost across the donor’s lifetime can be similar or lower under the CRT, depending on the four-tier characterization. The CRT also produces significant estate tax savings (the remainder is excluded from the estate at death), which Option A does not provide unless the donor’s gross estate is below the exemption.
The charitable remainder trust tax benefits are biggest when the donor has very low-basis property (a high embedded gain that the CRT defers entirely) and meaningful charitable intent. For donors with high-basis property, the gain deferral benefit is small and the CRT’s complexity may not be justified. For donors without meaningful charitable intent, the CRT forces 10%+ of the assets to charity at death, which is a real economic cost that should not be undertaken just for the tax benefits. The CRT should fit the donor’s actual goals, not the other way around.
Tax-exempt sale inside the trust is the single largest charitable remainder trust tax benefits component. The trust converts the entire appreciated asset to cash without triggering gain, allowing the full sale proceeds to be invested for the trust’s life. Compare to a direct sale where 32.7% of the gain is paid in tax up front. On a $10M asset with $8M of gain, the difference is $2.6M of additional investable capital inside the CRT versus the alternative. Compounded at 6% over 22 years (a typical CRT life expectancy), that $2.6M extra grows to roughly $9.4M of additional value inside the trust. That entire amount eventually flows to charity through the remainder, providing massive additional charitable impact compared to the direct sale path.
Lifetime income from the trust replaces the income the donor could have generated by investing the after-tax proceeds from a direct sale. The math depends on the spread between the trust’s investment returns and the donor’s tax rate on income. A CRT generating 6% annual returns and distributing 5% to the donor produces a stable income stream that gradually increases with trust value (in a CRUT). A direct sale invested in a similar portfolio generates similar gross income but is subject to ongoing taxation at the donor’s rates. Over decades, the after-tax income from the CRT often exceeds the after-tax income from the direct sale alternative because the four-tier rules can produce favorable characterization of distributions in later years (capital gain or return of corpus rather than ordinary income).
Estate planning advantages of the CRT are substantial but often overlooked in the analysis. The charitable remainder is excluded from the donor’s gross estate under §2055. For HNW donors with estate tax exposure (gross estates above the $13.99M exemption in 2025, (made permanent through 2034 by the One Big Beautiful Bill Act)), the CRT removes the contributed amount plus all subsequent growth from the estate. On a $10M contribution that grows to $14M by death, the estate tax savings at 40% on the $14M of removed assets would be $5.6M. That savings does not appear in a simple comparison of CRT versus direct sale because the estate component is a separate calculation, but it is real money that the CRT delivers and the direct sale does not.
The Reed Corporation runs full lifetime tax comparisons for clients considering a CRT against direct sale alternatives. The model accounts for the upfront deduction, the tax-exempt sale benefit, the four-tier income characterization, the lifetime income stream, the estate tax exclusion of the remainder, and the alternative direct-sale scenario invested in a similar portfolio with all taxes accounted for at the donor’s rates. The right answer often depends on facts that are not obvious from a generic comparison: the donor’s age, basis, intended charitable amount, expected longevity, state tax rates, and estate tax exposure. Charitable remainder trust tax benefits dominate for the right donor profile and underperform for the wrong one. The decision should always be data-driven and donor-specific, not based on general rules of thumb.
How do the charitable remainder trust tax benefits interact with state tax rules in New York and California?
Charitable remainder trust tax benefits at the state level largely mirror federal treatment for income tax purposes, but with important state-specific nuances that HNW donors should understand. New York fully conforms to federal §664 treatment of charitable remainder trusts. The trust itself is tax-exempt for New York state purposes. The donor’s upfront charitable deduction is allowed against New York state taxable income, with the same AGI limitations as federal. Distributions from the CRT to the donor are taxed under the same four-tier characterization as federal, at New York state rates plus NYC rates for city residents.
California similarly conforms to federal §664 treatment. The CRT is tax-exempt at the state level, and the donor’s charitable deduction is allowed against California taxable income subject to AGI limits. California rates run up to 13.3% on ordinary income and 13.3% on capital gains (no preferential rate at the state level). For California residents, the CRT’s tax-exempt sale of appreciated property produces dramatic state-level savings on top of the federal savings, because the alternative direct sale would have triggered up to 13.3% California capital gains tax. The CRT eliminates this state tax entirely on the trust’s internal sale.
Concrete example for a California resident. Donor sells $10M of appreciated stock with $2M basis directly: capital gain $8M, California state tax at 13.3% = $1.064M. Federal capital gains tax: $1.6M (20% plus 3.8% NIIT). Total tax: $2.66M on the direct sale. Contributing the same stock to a CRT eliminates both federal and state capital gains tax on the internal sale. The CRT’s investment proceeds are the full $10M rather than $7.34M after tax. The combined federal and state savings on the internal sale alone is $2.66M, which compounds inside the trust over the donor’s lifetime. The charitable remainder trust tax benefits at the state level are particularly large in high-tax states like California, where the state rate compounds the federal savings significantly.
Texas, Florida, Wyoming, and other no-tax states do not impose state income tax, so there is no state-level CRT analysis. The federal charitable remainder trust tax benefits work the same way regardless of state, but the comparative advantage versus a direct sale is smaller in no-tax states because the direct sale alternative does not incur state tax either. A donor in Texas comparing CRT versus direct sale is comparing federal taxes only. A donor in California or NYC is comparing federal plus state taxes, which makes the CRT relatively more attractive.
State residency change during the CRT term is a planning consideration for donors who may move states. The CRT itself follows the trustee’s location for state tax purposes in some states, while the donor’s distributions are sourced to the donor’s residence. New York and California both source CRT distributions to the donor’s state of residence at the time of distribution, regardless of where the trust is administered. A donor who moves from NYC to Florida after creating a CRT would have NYC-sourced distributions during the NYC residency period and Florida-sourced (no state tax) distributions during the Florida period. The move-state-then-distribute play does work for CRT distributions, unlike some other gain deferral structures where the state retains source-based jurisdiction.
Trust situs election can affect state taxation in some cases. A CRT created in a state with no income tax (Delaware, Nevada, South Dakota, Florida) and administered by a trustee in that state may avoid state-level taxation of any income retained in the trust. The donor’s distributions are still sourced to the donor’s residence, but the trust’s accumulated income (which is mostly invisible to the donor under the §664 tax-exempt framework anyway) is not taxed by the trustee’s state. This matters less for CRTs than for non-charitable irrevocable trusts because the §664 federal exemption already insulates the trust from federal income tax, but for state purposes the situs election can provide marginal additional savings.
California’s tax treatment of CRT distributions to non-residents who derived income from California-sourced contributions is a specific area of complexity. If a California resident contributes California real estate to a CRT and then moves out of California, California may attempt to source the eventual distributions back to California based on the original source of the contributed asset. The California Franchise Tax Board has been aggressive on this point for some related structures (monetized installment sales). For CRTs, the position is less established but should be considered. We generally advise California residents contributing California real estate to CRTs to either remain in California for the duration of the trust or to obtain a state tax opinion on the sourcing issue before moving.
NYC tax adds another layer for city residents specifically. The 3.876% city tax applies to all CRT distributions to NYC residents, on top of the New York state tax. For a NYC HNW donor receiving $400,000 of CRT distributions annually under tier-one ordinary income characterization, the combined state and city tax on that income is roughly $59,000. Add the federal tax (37% plus 3.8% NIIT on ordinary income) of $163,000, and total tax on the $400,000 distribution is $222,000, or 55.5%. NYC residents face the highest combined tax rates in the country on CRT distributions, which makes the comparison versus direct sale less favorable than it would be for residents of lower-tax jurisdictions.
The Reed Corporation works with HNW clients in New York and across the country to improve the state tax treatment of CRT planning. The state analysis is a small but real component of the overall CRT decision. For most clients, federal charitable remainder trust tax benefits dominate the analysis and state effects are secondary. For clients in California or New York with very large appreciated positions, the state tax savings from the CRT’s tax-exempt internal sale can be substantial and worth modeling explicitly. We do not recommend creating a CRT primarily for state tax reasons (the trust commitment is too significant for marginal state tax savings to justify), but for clients whose other factors favor a CRT, the state benefits add real value on top of the federal benefits.
What types of assets work best for funding a charitable remainder trust tax benefits structure?
The charitable remainder trust tax benefits work best with assets that combine three features: high embedded capital gain (low basis relative to FMV), liquidity or convertibility to liquidity, and absence of operating business complications that could create UBIT or qualification problems. Publicly traded stock and ETFs are the cleanest funding assets because they meet all three criteria. The trustee can sell them quickly without trustee fee complications, the embedded gain is preserved as deferred tax-exempt income inside the trust, and there are no UBIT issues with publicly traded securities. Most CRTs we set up are funded with publicly traded appreciated securities from concentrated positions or longstanding holdings.
Real estate is the second most common funding asset, especially for HNW clients with rental properties or development sites held for decades. Real estate with low basis and high FMV produces large embedded gains that the CRT defers tax-free. The trust sells the real estate after contribution and invests the proceeds in a diversified portfolio. The complications are mortgaged real estate (which triggers UBIT under §511 unless specifically structured to avoid it), real estate with deferred maintenance issues that could create environmental liability, and timing issues (the trust may need to hold the real estate for a period before sale, requiring careful trust drafting to handle the income during the hold period). NIMCRUT and Flip-CRUT structures address the income timing issue.
Closely-held business interests can work but require careful structuring. C-corporation stock contributions work cleanly because the corporation pays its own tax and the CRT just receives dividends or sale proceeds. S-corporation stock generally cannot be held by a CRT because the trust is not an eligible S-corporation shareholder under §1361. The S-corp termination problem can be avoided by converting to a C-corp before contribution, but the conversion itself may have tax consequences. Partnership interests can be contributed but the partnership’s activities may create UBIT exposure inside the CRT under §511 if the partnership has unrelated business activities. Most HNW clients contributing business interests need to engage attorneys to structure the contribution carefully.
Cryptocurrency is becoming a more common CRT funding asset for HNW clients with significant unrealized crypto gains. The IRS treats cryptocurrency as property for tax purposes, so a CRT can accept crypto contributions without recognizing gain. The trust then sells the crypto on a centralized exchange or through a custodian and invests the proceeds. The valuation at contribution must be supported by a qualified appraisal under §170(f)(11) for crypto contributions over $5,000. We have done several crypto-funded CRTs for clients with significant ETH or BTC positions that were too expensive to sell directly. The structure works the same way as for stock funding, with the appraisal being the main additional complication.
Art and collectibles can be contributed but the analysis is more complex. The charitable remainder trust tax benefits for art apply only if the trust sells the art rather than displaying it. If the trust must sell to generate income for the distributions, the related-use rule under §170(e)(1)(B) does not apply and the deduction is limited to cost basis rather than FMV. This significantly reduces the upfront charitable deduction for art contributions. Some donors prefer to fund the CRT with art only if they have charitable intent toward a museum that will display the art (related use applies), but this conflicts with the CRT’s eventual need to sell the art to generate income. Art is rarely the right asset for CRT funding.
Tangible personal property other than art (collectibles, vehicles, etc.) faces similar related-use issues and is rarely the right asset. Intellectual property (patents, copyrights, royalty streams) can be contributed but the income stream may be ordinary income that goes directly to tier one of the four-tier system, producing high-tax distributions. Self-created intangibles (where the donor created the IP) produce ordinary income on disposition under §1221, which the CRT inherits when it sells. The result is that all distributions from a CRT funded with self-created IP are likely ordinary income for the donor.
Mortgaged real estate triggers UBIT under §511. The trust holds an asset subject to acquisition indebtedness, and the income from the asset (rental income or sale proceeds) is subject to unrelated business income tax inside the trust. The UBIT rate is the trust tax rate (37% federal for top bracket, plus state). This dramatically erodes the charitable remainder trust tax benefits because the trust loses its tax-exempt status to the extent of UBIT income. The fix is to refinance the mortgage out before contribution (paying off the debt with other resources) or to use a CLAT (charitable lead annuity trust) instead, which has different UBIT rules. Most HNW clients should not contribute mortgaged real estate to a CRT without careful structuring.
Concrete asset selection example. HNW client has $20M of total appreciated assets: $8M low-basis Microsoft stock (basis $400K), $5M rental property with $2M mortgage and $1M basis, $3M of Bitcoin (basis $200K), $2M of art collection (basis equal to FMV), and $2M of S-corporation stock in a family business. The optimal CRT funding choice is the Microsoft stock and the Bitcoin: $11M of contributions with $10.4M of embedded gain that the CRT defers tax-free. The mortgaged real estate is excluded due to UBIT exposure. The art is excluded due to related-use issues. The S-corp stock is excluded due to qualification problems. The remaining $9M of assets stay outside the CRT for other uses (direct charitable gifts of cash from realized investments, life insurance funding, family inheritance).
The Reed Corporation works through the asset selection analysis for every CRT engagement. The optimal funding mix depends on the client’s overall asset profile, basis history, charitable intent, and operating business considerations. Not every appreciated asset belongs in a CRT, and trying to push the wrong asset into the structure creates problems that erode the charitable remainder trust tax benefits and may disqualify the trust. The asset selection conversation often takes longer than the CRT structure design because the choice of what goes in has more impact on the lifetime economics than the choice of CRAT versus CRUT or the specific payout rate.
How do the charitable remainder trust tax benefits work when the donor has a spouse?
Charitable remainder trust tax benefits in the context of married couples involve choices about who the income beneficiaries are, how the trust is structured for spousal succession, and how the planning interacts with the spouses’ joint tax position. The two most common spousal CRT structures are a joint-and-survivor CRT (income to both spouses while living, then to the survivor for life, then remainder to charity) and a single-life CRT (income to one spouse for life, then remainder to charity). Each has different actuarial and tax implications.
A joint-and-survivor CRT is the most common structure for married HNW couples. The trust pays income to both spouses while they are both alive, then to the survivor for the rest of his or her life, with the remainder to charity at the second death. The actuarial life expectancy used to compute the present value of the charitable remainder is the joint life expectancy of both spouses, which is longer than either single life expectancy. The longer life expectancy reduces the value of the charitable remainder interest and so reduces the upfront charitable deduction. For a couple both age 67, the joint life expectancy is roughly 28 years compared to 22 years for either single life, which lowers the remainder value by approximately 15% to 20%.
The upfront charitable deduction for a joint-and-survivor CRT funded with $10M at 5% payout is approximately $3.6M (compared to $4.3M for a single-life CRT with same facts). The deduction is smaller because the charity waits longer to receive the remainder. The income payments continue longer, providing income through both spouses’ lifetimes. The estate tax benefit at the second death is the same as for a single-life CRT (full §2055 deduction for the remainder to charity). The choice between joint-and-survivor and single-life depends on whether the couple needs the income continuation for the surviving spouse and how much they want to improve the upfront deduction.
Spousal portability of unused estate tax exemption interacts with CRT planning. The first spouse’s unused estate exemption (Deceased Spousal Unused Exclusion Amount or DSUEA) can be claimed by the surviving spouse if a §706 portability election is made. For couples with significant CRT contributions, the first spouse’s contribution to the CRT may not fully use their lifetime gift tax exemption, leaving exemption available for portability. The CRT itself does not consume gift tax exemption (the income interest retained by the spouse is excluded from gift treatment), so the exemption transfer to the survivor remains available for future gifting outside the CRT.
Marital deduction interaction is another consideration. Section 2056 provides an unlimited marital deduction for assets passing to a U.S. citizen spouse at death. If the first-to-die spouse contributed assets to a CRT during life with both spouses as income beneficiaries, the surviving spouse’s continuing income interest in the trust may qualify for the marital deduction if specific QTIP-like conditions are satisfied. Section 2056(b)(8) provides a special election for CRT income interests passing to the surviving spouse. This election allows the income interest to qualify for the marital deduction, deferring estate tax on the first spouse’s contribution until the second death.
The charitable remainder trust tax benefits for a divorcing couple raise unique issues. The CRT is irrevocable, so a divorce does not unwind the trust. The income payments continue according to the trust document. If both spouses are income beneficiaries, both continue to receive payments after divorce, which often defeats the divorcing parties’ goals of financial separation. The trust document can sometimes be modified by court order or with consent of all parties (including the charitable remainder beneficiary), but the modification options are limited. Divorce planning around a CRT is a specialized area that we coordinate with the client’s divorce attorney when applicable.
Concrete example. Couple age 65 and 63 contribute $15M of appreciated stock to a joint-and-survivor CRUT with 5% payout. Upfront charitable deduction: approximately $5.4M (lower than single-life CRT due to longer joint expectancy). Annual income payments start at $750,000 and scale with trust value. Upon first spouse’s death (assume age 85, 20 years out), trust continues to pay surviving spouse. Upon second death (assume age 88 for survivor, 25 years out), trust distributes remainder to charity. Total lifetime income to the couple: perhaps $25M to $35M in nominal dollars. Estate tax savings: depends on estate size, but the full remainder is excluded from both estates.
Survivor planning is important for the income beneficiary arrangement. If the donor wants the income payments to continue to a non-spouse beneficiary after death (a child or other family member), the trust document can include the non-spouse as an income beneficiary, but the upfront charitable deduction is reduced because the income interest is longer. The IRS imposes specific limits on what types of non-charitable beneficiaries can be named. The general rule is that the income beneficiaries must be living at the trust’s creation. The trust cannot have continuing income payments to unborn beneficiaries or to indefinite class beneficiaries.
The Reed Corporation works with married HNW clients to improve the CRT structure for the couple’s overall tax and estate plan. The choice of single-life vs joint-and-survivor, the choice of payout rate, the inclusion of secondary beneficiaries, and the integration with marital deduction planning all affect the outcome. For most HNW couples with charitable intent and significant appreciated assets, the joint-and-survivor CRT is the right answer because it provides income security for both spouses while preserving the charitable benefits. The slightly lower upfront deduction is more than offset by the longer income stream and the planning flexibility. The charitable remainder trust tax benefits work well for married couples when the structure is calibrated to their specific situation rather than using a generic template.
One last spousal point. Surviving spouse considerations in CRT planning extend beyond the income beneficiary structure. The trustee should be empowered to handle the surviving spouse’s specific needs, including potential distributions for medical care, long-term care, or other extraordinary expenses. Most CRT documents include hardship distribution provisions that allow the trustee to make additional distributions beyond the regular payment schedule under defined circumstances. The hardship provisions must be drafted carefully to avoid compromising the §664 charitable remainder requirements. We coordinate with the client’s estate planning attorney on the spousal provisions to make sure the structure provides genuine flexibility for the surviving spouse while preserving the charitable remainder trust tax benefits.
Can I change the charitable beneficiaries or unwind a charitable remainder trust tax benefits structure?
The charitable remainder trust tax benefits depend on the trust being irrevocable, which means substantial modifications after creation are limited. The donor cannot reclaim the contributed assets, cannot redirect the remainder to non-charitable beneficiaries, and cannot fundamentally restructure the trust without consequences. However, certain modifications are permitted and others can be accomplished through court proceedings or with IRS approval. The flexibility depends on what the donor wants to change and how it was originally drafted.
Changing the charitable remainder beneficiary is often permitted by the trust document itself. Many CRTs include a power for the donor to substitute charitable beneficiaries during life, as long as all replacement charities qualify as §501(c)(3) public charities. This power allows the donor to change which charities ultimately receive the remainder without affecting the upfront deduction or the trust’s qualification. The donor exercises the power by written direction to the trustee. The change does not require IRS consent or court approval. We recommend including this power in CRT drafting to give the donor flexibility to redirect the charitable benefit if circumstances change.
Changing the income payment terms is more restricted. The payout rate and the income beneficiaries are set at trust creation and generally cannot be changed without disqualifying the trust. Section 664 imposes strict requirements on the payment structure (5% to 50% payout, term not exceeding 20 years or life of named individuals, 10% remainder). Modifications that violate these requirements convert the trust to a non-qualifying CRT, which retroactively eliminates the tax-exempt status and the upfront deduction. This is catastrophic and reversible only through extensive remediation work with the IRS.
Some modifications are permitted by Rev. Rul. 2008-41 and related guidance. The IRS allows certain administrative modifications to CRTs through state court proceedings, as long as the modifications do not affect the trust’s qualifications under §664. Permitted modifications include changes to trustee, changes to administrative provisions (investment authority, distribution mechanics), and changes to non-essential terms. State court reformation of trust terms is generally available for technical drafting errors or for modifications that all interested parties (including the charitable beneficiaries) consent to.
Unwinding a CRT entirely is the most extreme modification and is rarely available. The trust is irrevocable. The donor cannot reclaim the assets. The trust can be terminated early by distributing all assets to charity (giving up the income interest), which the donor may do but typically would not because it forfeits the income stream that motivated the original contribution. A successful private letter ruling from the IRS could potentially allow trust termination with redistribution to the donor for certain compelling reasons, but this is exceedingly rare and not a planning option that should be relied on.
Section 664(d)(4) provides a specific termination mechanism: the income beneficiaries can sell or assign their income interest to the charitable remainder beneficiary, effectively collapsing the trust into immediate charitable receipt. The donor receives nothing for the income interest assignment (or only a return of the present value, depending on structure). This unwind path is sometimes useful when the donor’s circumstances change and the income stream is no longer needed, allowing the assets to flow to charity earlier. The donor may receive a small additional charitable deduction for assigning the income interest. The path is rarely used because most donors want to preserve the lifetime income.
Trust splitting and recombining are more complex modifications that can be accomplished in some circumstances. If a donor has a CRT with multiple income beneficiaries and wants to split into separate trusts for each beneficiary (perhaps to allow different investment management or different beneficiary needs), the split can be done with IRS approval in certain cases. PLRs have approved various splits and recombinations of CRTs. The work requires private letter ruling guidance and significant legal expense.
Real example. Client created a CRUT in 2015 with three charitable beneficiaries: her alma mater, a hospital foundation, and a wildlife conservation organization. By 2025, she had become disenchanted with the wildlife organization due to leadership changes and wanted to redirect that share to a different charity. The CRT document included a power to substitute charitable beneficiaries, so she exercised the power by written direction to the trustee replacing the wildlife organization with a different §501(c)(3). The change was effective immediately, did not require IRS or court approval, and did not affect the trust’s qualification. The new charity is now the beneficiary of that share of the remainder.
Compare with another client who created a CRT in 2010 with her three children as income beneficiaries (a multi-life structure with substantial actuarial complexity). By 2024, she wanted to change the payment structure to provide more income to one child who had developed health issues. The CRT did not allow modification of income beneficiaries, and §664 generally prohibits material modifications to the income interest. Adding additional income to one child without reducing the others would have required IRS approval and may have disqualified the trust. The client ultimately did not pursue the modification because of the risk to the trust’s qualification. She instead supplemented the child’s needs from other sources.
The Reed Corporation drafts CRTs with maximum flexibility within the §664 framework, including powers to substitute charitable beneficiaries and to make administrative modifications, while recognizing that the income terms and the basic structure must remain stable to preserve the charitable remainder trust tax benefits. Clients considering a CRT should understand that the structure is irrevocable in the most important respects. The trade-off is real: the donor gives up flexibility in exchange for the substantial tax benefits and the lifetime income. For clients who need substantial future flexibility, alternative structures (donor-advised funds, private foundations, or revocable trusts paired with annual gifts) may be better fits than the irrevocable CRT. The decision to create a CRT should be informed by a clear understanding of what can and cannot be changed once the trust is in place.
One final practical note on modification options. The Reed Corporation works with clients whose original CRT structures no longer fit their current circumstances. The options are limited (the trust is irrevocable) but not zero. The most common adjustments are charitable beneficiary substitutions (where allowed by the trust document), administrative provision updates through state court reformation, and trustee changes. These adjustments preserve the underlying charitable remainder trust tax benefits while accommodating evolving circumstances. The conversations are often emotional because the donor may feel locked into a structure that no longer reflects their values or family situation. We approach these reviews with empathy and creativity, looking for the maximum flexibility within the §664 framework. Some adjustments simply are not possible. Others can be accomplished with care. The right starting point is understanding what the trust document actually allows.
