Charitable Remainder Trust for Appreciated Stock: The Real Decision Framework

CRT in sixty seconds — CRUT vs. CRAT

A charitable remainder trust is an irrevocable split-interest trust under IRC Section 664. The donor contributes appreciated property — typically long-term-held concentrated stock — to the trust. The trust sells the property and recognizes no capital gain at the trust level (the trust itself is tax-exempt under Section 664(c)). The trust then pays the donor or another named non-charitable beneficiary an annual income stream for a stated term — up to 20 years, or for the life of one or more measuring beneficiaries. At termination the remainder passes to one or more qualified Section 170(c) public charities (or a private foundation, with a lower deduction limit). The donor receives a partial charitable income-tax deduction at funding equal to the present value of the remainder interest, computed under Treas. Reg. Section 1.664-1 using the IRS Section 7520 interest rate.

Two structural variants exist. A CRAT (Charitable Remainder Annuity Trust, Section 664(d)(1)) pays a fixed dollar amount each year, set at funding as a percentage of the initial fair market value between 5% and 50%. A CRUT (Charitable Remainder Unitrust, Section 664(d)(2)) pays a fixed percentage of the trust's annually revalued fair market value, also between 5% and 50%. The CRUT's annual revaluation absorbs market volatility without breaching the 5% floor; the CRAT's fixed dollar amount can deplete a trust in a bad market or cause it to fail the 5%-floor test in some configurations. For appreciated concentrated stock in a long-horizon vehicle, the CRUT dominates in practice; CRATs persist mainly in short-horizon or fixed-income-need configurations.

The economics for the household resolve to four levers: the trust term (up to 20 years or for-life), the payout rate (5%–50%, with the Section 7520 / 10%-remainder math constraining the upper end in practice), the Section 7520 rate at funding (a federal interest rate published monthly by the IRS, used in the present-value math), and the asset profile inside the trust after the day-one sale. Sections 4 and 5 work the numbers.

The three benefits — deduction, tax-deferred sale, income stream

Benefit one: a partial charitable deduction at funding. The deduction equals the present value of the remainder interest as computed under Treas. Reg. Section 1.664-2 (CRAT) or Section 1.664-3 (CRUT) using the Section 7520 rate in effect either in the month of funding or in either of the two preceding months (donor's election under IRC Section 7520(a)). For a 20-year CRUT funded with $2M of appreciated stock, paying 5%/year, at a Section 7520 rate of 5.4%, the remainder factor under the IRS unitrust tables is approximately 0.34 — yielding a deduction of approximately $680K. For contributions of long-term appreciated property to a public charity, the deduction is limited to 30% of the donor's adjusted gross income (per IRS Publication 526) with a five-year carryforward of any unused amount; the 20% AGI ceiling applies if the remainder beneficiary is a private foundation rather than a public charity.

Benefit two: tax-deferred sale of the appreciated stock inside the trust. Once the donor contributes the stock, the trust holds the basis the donor had at contribution. The trust sells the stock and recognizes no capital gain at the trust level — Section 664(c) makes the trust tax-exempt for income tax purposes, subject to the unrelated-business-taxable-income exception under Section 664(c)(2) for years in which the trust receives UBTI (uncommon for CRTs holding marketable securities). The household's embedded gain on the contributed stock is therefore not recognized at sale; it is preserved inside the trust and flows through to the income beneficiary on subsequent distributions under the four-tier WIFO ordering rule (covered in Section 6).

Benefit three: a multi-year income stream to the donor or other non-charitable beneficiary. The trust pays the income beneficiary the stated amount each year for the trust's term, regardless of whether that beneficiary is the donor, the donor and spouse jointly, or a non-spouse relative. The stream is taxed under the four-tier WIFO ordering rule of Treas. Reg. Section 1.664-1(d)(1): distributions are deemed to come first from accumulated ordinary income, then accumulated capital gain, then accumulated tax-exempt income, then corpus. For a CRT funded with $2M of low-basis META and immediately diversified in-trust, tier 2 (the embedded $1.7M of capital gain) is large; income distributions to the donor are taxed as long-term capital gain until that pool is exhausted, then shift to whatever the trust earns going forward.

The three costs — irrevocability, 10% remainder hurdle, complexity

Cost one: irrevocability. A Section 664 CRT is irrevocable on funding. The donor cannot withdraw the principal, cannot remove the charitable remainder beneficiary, and cannot redirect the income stream meaningfully (a power to substitute one Section 170(c) public charity for another is permitted; that is the only meaningful retained power consistent with Section 664 status). If the household needs the principal — for a home purchase, business funding, divorce, medical event, or any other large household liquidity need — the CRT cannot fund it. Court-ordered commutations (early termination by agreement among trustee, income beneficiary, and remainder charity) are theoretically possible but expensive, slow, and treated as taxable events; commutation should not be planned for at funding. The right working assumption is that the contributed principal is gone permanently.

Cost two: the 10% remainder hurdle. Under IRC Section 664(d)(1)(D) and Section 664(d)(2)(D), the present value of the charitable remainder must be at least 10% of the contributed property's fair market value at funding. The present value depends on the Section 7520 rate, the trust term, and the payout rate. Higher payout rates and longer terms reduce the present-value remainder. In a moderate-Section 7520 environment (5–6%), a 20-year CRUT with a 5% payout clears the 10% hurdle by a comfortable margin (remainder factor near 0.34); a 20-year CRUT pushed to a payout above roughly 11% can fail the test; and a CRT for a young donor (term-of-life with a long actuarial expectancy) at even a moderate payout rate frequently approaches or fails the 10% threshold because the longer expected payout stream drives the present-value remainder below the floor. Term-of-years CRUTs are statutorily capped at 20 years under Section 664(d)(2)(A), so a longer fixed term is not a permitted lever. If the math fails the 10% test, the trust is not a qualified Section 664 CRT, the entire transaction unwinds — gain is recognized at contribution, no charitable deduction is allowed, and the structure is simply a botched gift. The 10% hurdle is the most common reason a planned CRT fails on the spreadsheet; it is also the constraint households most often try to engineer around, and the math should be confirmed by a competent estates-and-trusts attorney before any funding.

Cost three: complexity and ongoing administration. CRTs are not set-and-forget. The trust must file IRS Form 5227 (Split-Interest Trust Information Return) annually; the income beneficiary receives a K-1 disclosing the four-tier character of distributions; the trust has trustee duties (investment, distribution, recordkeeping) that compound for the trust's entire term; the trust is subject to the private-foundation-style rules of Section 4941 (self-dealing), Section 4942 (insufficient distributions), Section 4944 (jeopardy investments), and Section 4945 (taxable expenditures) by cross-reference under Section 4947(a)(2). Self-dealing in particular — any transaction between the trust and the donor or a related party — is a hard-line prohibition policed by excise tax. The carrying cost of a CRT is typically 0.75–1.50% per year, all-in, which is material relative to a low-cost direct-indexing SMA at 0.30–0.50%.

Worked example — $2M META + 20-year CRUT

Anna is a senior staff engineer at META, household income approximately $850K, marginal federal bracket 37% on ordinary income / 23.8% on long-term capital gain (top LTCG + NIIT under Section 1411), California resident at 13.3% top bracket. She holds $2M of META at $300K basis (12-year tenure, mix of NSO exercise + RSU vest accumulating since 2014). Her plan over the next decade is to give approximately $1M to a named public charity (her university and a community foundation, in roughly equal parts). She funds a 20-year CRUT paying 5% of net fair market value annually, with herself as sole income beneficiary, the named public charities as remainder beneficiaries.

At funding (Year 0). Anna contributes the $2M META block to the CRUT in March 2026. The Section 7520 rate for March 2026 is approximately 5.4% (representative; verify the actual published rate at funding). Under the IRS unitrust remainder factor tables, a 20-year CRUT at 5% payout and 5.4% Section 7520 produces a remainder factor of approximately 0.34 — yielding a charitable income-tax deduction of approximately $680K. The deduction is limited to 30% of Anna's AGI ($255K cap in year 1 against $850K AGI); the unused $285K carries forward five years (Pub 526). Federal tax savings on the year-1 usable deduction at 37% ordinary bracket: $94K; full deduction used over 1–3 years saves approximately $252K of federal tax cumulatively. California similarly conforms to the federal charitable deduction (California R&TC Section 17201) and produces additional state-level tax savings of approximately $70K–$90K depending on the income path.

Day-one in-trust sale. The trustee sells the $2M META on the day after funding for approximately $2M (assume no material market movement). The trust recognizes zero capital gain at the trust level — Section 664(c) exempts the trust. The trust reinvests the full $2M in a diversified portfolio (typically a mix of broad equity index funds, fixed income, and possibly a managed alternative sleeve, depending on the trustee's investment policy). The trust's tier-2 capital-gain account is now $1.7M (the embedded gain on the contributed stock).

Years 1 through 20 — income stream. The CRUT pays Anna 5% of net fair market value each year. At an initial $2M, the year-1 payment is $100K. Assuming the trust earns the payout rate net of fees over the trust term, the annual payment fluctuates with portfolio value but averages roughly $100K–$120K nominal. Under the WIFO ordering rule, distributions to Anna are taxed as long-term capital gain (federal) — at her 23.8% federal LTCG rate plus 13.3% California ordinary rate (California does not have a preferential LTCG rate; capital gain is taxed as ordinary at the state level), stacking to a 37.1% blended effective rate on the capital-gain character — until the $1.7M tier-2 account is exhausted, approximately 17 years at the 5% payout rate. After year 17, distributions shift character to whatever the trust is earning in the relevant year (likely a mix of dividend / interest / smaller capital gain), at the beneficiary's then-current rates. Cumulative nominal distributions to Anna across the 20-year term are approximately $2.0M — roughly equal to the contributed principal at constant corpus — at an effective long-term rate roughly aligned with the LTCG plus state rate during the tier-2 window and ordinary plus state rate thereafter.

At termination (Year 20). Whatever remains in the trust passes to the named public charities. The remainder amount depends on the realized return path; for a 20-year horizon, a return roughly equal to the 5% payout rate produces a remainder near the contributed principal ($2M ± fluctuation), while a return that exceeds the 5% payout rate produces a larger remainder. A typical 60/40-ish institutional asset allocation, achieving 6.5–7.5% long-run nominal returns, produces a remainder of roughly $2.4M–$3.0M; a more aggressive allocation that achieves 8–9% produces a remainder of roughly $3.5M–$4.5M. The charity receives the remainder in cash or in-kind at the trustee's discretion under the trust agreement.

Ten-year scoreboard vs. sell-and-redeploy alternative. Selling the $2M META outright in 2026 recognizes $1.7M of LTCG at 23.8% federal LTCG plus 13.3% California ordinary (California taxes capital gain as ordinary income at the state level, so the stack is 23.8% + 13.3% = 37.1% blended on the capital-gain character), for approximately $631K of total tax — net $1.369M to redeploy. The CRT preserves the full $2M in pre-tax exposure inside the trust and produces approximately $252K of federal tax savings from the deduction. After 10 years, Anna has received approximately $1M of cumulative income from the CRT (taxed at LTCG-equivalent rates under WIFO) plus the $252K federal deduction benefit, while the $2M-pre-tax sleeve inside the trust grows on a tax-deferred basis. The sell-and-redeploy alternative starts with $1.369M net and grows on a fully-taxable basis (annual rebalancing-driven realizations, drag of 0.5–1.0% per year in a high-bracket household). The CRT wins on after-tax cumulative cash flow + remainder if and only if the household genuinely values the eventual charitable remainder — that is, if the $2M+ remainder represents a charitable outcome the household would have funded anyway. Without that charitable intent, the sell-and-redeploy alternative dominates because Anna keeps the eventual remainder principal.

CRT vs. donor-advised fund plus direct gifting

The donor-advised fund (DAF) plus direct gifting is the most common alternative to the CRT for a charitably-inclined household with appreciated stock. Mechanically: the donor contributes appreciated stock to a DAF (Schwab Charitable, Fidelity Charitable, Vanguard Charitable, or a community foundation), receives a charitable income-tax deduction at the contribution's full fair market value (subject to the same 30%-of-AGI public-charity ceiling under IRS Publication 526), and the DAF sells the stock with no capital-gain recognition (the DAF is a Section 501(c)(3) public charity and is tax-exempt). The donor then directs grants out of the DAF to qualified charities over time. The contributed principal is gone permanently — there is no income stream back to the donor.

The CRT-vs-DAF tradeoff resolves to two questions: does the household want an income stream, and does the household want to control the deduction's magnitude. If the household does not need the income stream, the DAF is generally the better tool: the deduction is the full FMV ($2M in the worked example, vs. $680K for the CRUT), the capital-gain avoidance is identical, the operating cost is far lower (DAFs typically charge 0.60–1.00% all-in vs. a CRT's 0.75–1.50%), the DAF is not irrevocable in the same hard sense (the donor retains advisory privileges over grant timing and can spread giving over many years), and there is no Form 5227 / K-1 administrative overhead. The DAF is a strictly better deduction for the household that does not need or want the multi-year income stream.

The CRT's advantage over the DAF lives entirely in the income stream. A household with a low ordinary-income pension-equivalent need post-retirement, or a household with a current high-tax-bracket year that wants to bridge income to a future lower-tax-bracket retirement, may find the CRT's annuity-like cash flow worth more than the larger DAF deduction. The decision should be made on cash-flow modeling that prices both structures against the household's actual income and giving plan, not on the marketing framing that “CRTs let you give and still receive income.” Many households who fund CRTs would have done strictly better with a DAF.

CRT vs. exchange fund — when the CRT wins

The exchange fund (covered in detail at /strategies/exchange-funds for the Section 721 traditional partnership-based version, and at /strategies/section-351-exchange-funds for the Section 351 ETF-conversion version) is the deferral-only alternative to the CRT. The exchange fund preserves the household's claim on principal — at the seven-year hurdle the contributor receives a diversified basket back in-kind under Section 732 and retains the embedded gain to recognize on a chosen schedule. The CRT trades that principal claim permanently for the deduction plus the income stream plus the charitable remainder.

The CRT beats the exchange fund only when three conditions hold simultaneously. First, real charitable intent. The household genuinely plans to give the remainder amount to charity, and the remainder amount approximates what they would have given anyway in the absence of any tax structure. If the household wouldn't otherwise give $2M+ to charity, the CRT's remainder represents principal the household is permanently giving up that the exchange fund would have preserved. Second, time horizon long enough for the income stream to compound and for the deduction to be fully used. Short-horizon CRTs (under 10 years) often produce smaller cumulative income than the Section 721 exchange-fund-plus-redemption alternative, especially when the Section 7520 rate is high relative to the payout rate. Third, top federal bracket plus high state tax. The deduction's after-tax value scales with the donor's marginal rate; a 24%-bracket household in a no-state-income-tax state captures less than half the deduction value of a 37%-federal + 13.3%-CA household, and the CRT-vs-exchange-fund math tilts back toward the exchange fund when the deduction is worth less.

In the four-condition wrong-tool framing of the Section 721 exchange-fund guide (position below ~$1M, charitable intent, illiquidity intolerance, expected outperformance), the CRT is the right alternative for the second condition — the household with charitable intent. For the other three, the CRT is not a substitute; the Section 351 ETF-conversion fund, direct indexing, or 130/30 long-short extension are the appropriate alternatives. The CRT is a charitable tool with tax advantages, not a tax tool with charitable side-effects; treating it as the latter is how households end up with irrevocable trusts they later regret.

CRT vs. selling and donating proceeds — the math

A simpler third alternative for a charitably-inclined household is to sell the appreciated stock outright, pay the capital-gains tax, and donate the after-tax proceeds. At the $2M META example, selling outright produces $1.7M of LTCG at 23.8% federal LTCG plus 13.3% California ordinary (CA does not have a preferential LTCG rate), blending to a 37.1% effective rate on the capital-gain character — roughly $631K of tax — leaving $1.369M to donate. A direct donation of the $1.369M cash to a public charity yields a full $1.369M deduction (limited to 60% of AGI under Section 170(b) for cash gifts, with a 5-year carryforward). At a 37% ordinary bracket, the cash donation saves approximately $507K in federal tax (net: $507K − $0 because the cash is already after-tax) for a net charitable cost to the household of approximately $862K relative to keeping the stock. The charity receives $1.369M.

A CRT in the same circumstances produces a $680K deduction (approximately $252K of federal tax savings), an income stream of approximately $2.0M nominal across the trust term, and a remainder of approximately $2.4M–$3.0M to the charity (return-path-dependent at a 6.5–7.5% net return). The CRT produces more total economic value to the household-plus-charity combined than the sell-and-donate alternative: the CRT preserves the embedded gain inside the trust and compounds it tax-deferred for 20 years. But the CRT's benefit is split: the household receives the income stream and the smaller deduction; the charity eventually receives the larger remainder.

The simpler comparison is: donate-the-stock-directly vs. fund-a-CRT. Donating the stock directly to a public charity (or a DAF) produces a $2M deduction — roughly $740K of federal tax savings at 37% — and the charity receives the full $2M immediately. The CRT produces a $680K deduction and the charity receives the $2.4M–$3.0M remainder 20 years later. The direct-donation option gives the household more current tax benefit and the charity more current funding; the CRT gives the household the income stream and the charity a larger eventual remainder. Households should not fund a CRT solely for the deduction — the direct-donation alternative beats the CRT's deduction by roughly 4x on the deduction line. The CRT's case lives in the income stream.

State-specific CRT mechanics — California and New York

California. California conforms to the federal charitable income-tax deduction at the individual level (R&TC Section 17201) and recognizes Section 664 trusts as tax-exempt for state income-tax purposes parallel to the federal Section 664(c) treatment. A California-resident donor funding a CRT with appreciated stock receives the federal deduction at funding (subject to the 30%-of-AGI public-charity ceiling) and a California state deduction roughly mirroring the federal amount (subject to California's own AGI ceilings and its limitation on itemized deductions in some high-income brackets). The state-tax savings on the worked $680K deduction at the 13.3% California top rate is approximately $70K–$90K depending on the household's AGI path. The day-one in-trust sale of the contributed META is also tax-free at the state level — California conforms to the Section 664(c) trust-level exemption. There is no California-specific structural complication; the CRT is a usable tool in California, and the high state rate makes the deduction's after-tax value materially higher than in a no-state-income-tax state.

New York. New York follows a similar pattern. The state conforms to the federal charitable deduction (NY Tax Law Section 612) and recognizes Section 664 trusts as exempt at the state level. The state-tax savings on the worked $680K deduction at New York's 10.9% top state-plus-NYC rate (combined approximately 14.776% for high-income NYC residents) is approximately $75K–$100K. New York has historically applied additional scrutiny to trusts with non-resident trustees — the resident/non-resident trust classification under NY Tax Law Section 605(b)(3)(D) affects the trust's state-tax exposure on items not exempted by Section 664(c) (rare for marketable-securities-funded CRTs but relevant for trusts that later hold real estate or partnership interests). Use a New York-experienced trustee or attorney for any New York CRT funding; out-of-state trustees with no operational New York presence can in some configurations create state-residency questions.

Other states: most states conform to the federal Section 664 treatment; a small number of states (historically Pennsylvania for partnership trust treatment, and a few others for specific income-character questions) have non-conforming rules that require state-specific advice. Verify with state-specific tax counsel before funding in any state with non-standard trust-tax rules.

Setup costs and ongoing administration

Drafting and setup. A competent estates-and-trusts attorney typically charges $5,000–$15,000 to draft a CRT, depending on the complexity of the beneficiary structure, the trustee arrangement, and any customizations. The IRS has published sample forms for CRUTs and CRATs in Rev. Procs. 2003-53 through 2005-58, which experienced practitioners adapt rather than draft from scratch — using a non-IRS-form structure invites qualification challenges and is rarely worth the cost savings. Setup also involves obtaining a trust EIN, opening the trust's brokerage account, and executing the in-kind transfer of the contributed stock from the donor to the trust before the trustee initiates the day-one sale.

Trustee selection. Three trustee models are common. (1) An institutional trustee — a bank trust department (Northern Trust, Wells Fargo, Fiduciary Trust) or a community-foundation trustee — typically charges 0.50–1.00% per year of trust assets for a combined trustee-plus-investment-management service. (2) A family-member or individual trustee (often the donor's spouse or adult child) plus a separately retained investment manager runs roughly 0.50–0.85% combined. Self-trusteeing has self-dealing risk under Section 4941 if not carefully managed and is not generally recommended unless the donor has trust-administration experience. (3) A community foundation acting as both trustee and remainder beneficiary is the lowest-friction option for households whose intended remainder is a community-foundation grant pool; the foundation runs the trust at cost in many cases.

Annual administration. The trust files IRS Form 5227 (Split-Interest Trust Information Return) annually, reporting trust income, distributions, and the four-tier WIFO ordering. The income beneficiary receives a K-1 showing the character of distributions for inclusion on the beneficiary's personal return. Tax-preparation costs typically run $1,500–$4,000 per year for a marketable-securities CRT; CRTs holding real estate, partnership interests, or other complex property cost more.

Compliance traps. Self-dealing under Section 4941 (any transaction between the trust and the donor or related parties) is policed by excise tax and is the highest-frequency operational mistake — common variants include the donor purchasing real estate from the trust, the trust loaning the donor cash, or the trust paying the donor for services. Insufficient distributions under Section 4942, jeopardy investments under Section 4944, and taxable expenditures under Section 4945 are technically applicable by cross-reference through Section 4947(a)(2) and require trustee diligence on the trust's investment policy and distribution mechanics. These are not theoretical risks; they are the items that drive most CRT IRS examinations and are why an experienced trustee is worth the fee delta over a self-trusteed arrangement.

When a CRT is the wrong choice — five scenarios

No marketing-driven CRT article writes this section in a real way; the trustees and attorneys who run the CRT market are paid to set up CRTs, not to disqualify prospective donors. The fiduciary perspective is the opposite — the household's after-fee, after-tax outcome and the actual charitable mission are the only things that matter, and the CRT produces a worse outcome in five recurring situations.

1. The charitable intent isn't real. The most common failure mode. A household intrigued by the deduction or by “the trust pays you income for 20 years” framing funds a CRT without an honest charitable mission. The right gut-check: would the household plan to give the eventual remainder ($2M–$3M in the worked example) to charity even if the tax structure didn't exist? If the answer is no, the CRT is functionally trading a $680K deduction for permanent loss of $2M–$3M of principal — the household would be better off with an exchange fund (if diversification is the goal) or sell-and-redeploy (if redeployment is the goal). The CRT is not a tax structure with a charitable side-effect; it is a charitable structure with a tax efficiency.
2. Household needs principal liquidity within the trust term. Life events that need cash — home purchase, business funding, divorce, medical, college, family health — will arise. The CRT is irrevocable; the trust cannot fund those events. Court commutations are expensive, slow, and taxable. Households at the median of life-event timing (early- to-mid career, growing family, mortgages within ten years) routinely overestimate their multi-decade principal-liquidity tolerance. Donate stock to a DAF and keep the principal-redeployment optionality with a Section 721 exchange fund or direct indexing instead.
3. The 10% remainder hurdle fails. A young donor with a long term-of-life expectancy plus a moderate-to-high payout rate frequently fails the Section 664 10% test. A 35-year-old funding a life-of-donor CRUT paying 6%+ in a low-Section 7520-rate environment can fail the test by enough that no payout-rate-and-term combination rescues it. When the math fails, the structure is not a Section 664 CRT — it is a botched gift. Confirm the math before signing; restructure (shorter term, lower payout, higher Section 7520 election if available) or abandon the structure entirely if the math does not clear.
4. Position size below approximately $500K. The fixed setup cost of $5K–$15K plus annual carrying costs of 0.75–1.50% become inefficient below approximately $500K of contributed value. A household with $250K of appreciated stock and charitable intent is far better served by a DAF (no setup cost; combined administrative fee under 1%/year), an outright donation of the stock to a public charity, or an exchange fund if diversification is the primary goal. Below the $500K floor the CRT is mostly fees.
5. The deduction does not clear the Section 170 AGI floor in a usable way. A household with low ordinary AGI relative to the contribution size — for example, a recently retired tech employee with $200K of annual ordinary income contributing $2M of appreciated stock — cannot fully deduct the $680K partial-remainder value within the 30%-of-AGI ceiling plus 5-year carryforward window. The deduction's present-value after-tax benefit is materially lower than the nominal $680K suggests, and the CRT's cost-benefit math swings against funding. The fix is sometimes to defer funding by 1–2 years to a higher-AGI window, or to size the contribution smaller to fit within the AGI ceiling cleanly.
