Charitable Remainder Trust Design Guide

Not tax or legal advice — CRT design depends on your specific asset mix, income needs, and charitable goals. Use this as a framework before talking to a specialist.

What a CRT does — and why it matters for large appreciated assets

A Charitable Remainder Trust (CRT) is an irrevocable trust that converts a large, highly appreciated asset — stock, real estate, a business interest — into an income stream for you or a family member, with the remaining trust assets passing to charity when the trust ends. Three things happen simultaneously when you fund one:

Capital gains avoidance on the initial transfer. You contribute appreciated assets to the trust. No capital gains tax is triggered at the time of transfer — you've donated the asset to a tax-exempt entity. The trust sells and reinvests the full pre-tax proceeds, which are now working for you rather than the IRS.
An income tax deduction today. You receive a partial charitable deduction in the year you fund the trust — the present value of what the charity is expected to receive at the end of the trust term.¹
An income stream for life or a fixed term. The trust pays you (or designated beneficiaries) annually until it terminates — typically either over your lifetime or a fixed term up to 20 years.

A concrete example: You have $1.5M of low-basis stock ($150,000 cost basis). Selling triggers roughly $254,000 in federal capital gains tax (20% LTCG + 3.8% NIIT on the $1.35M gain). If instead you contribute the stock to a 7% CRUT for your joint lifetime (age 65/63, April 2026 §7520 rate of 4.6%), the trust sells tax-free, reinvests $1.5M, and pays approximately $105,000/year. You also receive an immediate partial charitable deduction (the present value of the remainder), and that $254,000 that would have gone to taxes now generates returns inside the trust for decades.

Two types: CRUT vs CRAT

All CRTs come in two forms. The choice is a significant design decision that affects your income security, tax deduction, and flexibility.

Feature	CRUT (Charitable Remainder Unitrust)	CRAT (Charitable Remainder Annuity Trust)
Payout method	Fixed % of trust value, revalued each year	Fixed dollar amount set at creation, never changes
Payout range	5%–50% of annual fair market value²	5%–50% of initial contribution value²
If markets rise	You receive more income	Income stays the same
If markets fall	You receive less income	Income stays the same (trust may be depleted faster)
Additional contributions	Allowed	Not allowed after initial funding
Charitable deduction	Slightly smaller (more uncertainty for charity)	Slightly larger (fixed remainder is more predictable)
Best for	Inflation protection; adding assets over time; longer horizons	Guaranteed income; shorter time horizons

Most HNW donors working with a specialist choose a CRUT over a CRAT. CRUTs allow additional contributions (you can fund the same trust again in future years), and the inflation-linked payments are more appropriate for a long lifetime horizon. CRATs are harder to pass the 10% remainder test for older donors at higher payout rates, and the fixed-dollar payout loses purchasing power over decades.

CRUT subtypes: Flip CRUT and Net Income CRUT

Specialized CRUT variants address situations where the initial assets produce little current income before a sale (real estate, illiquid business interests):

Net Income CRUT (NICRUT): Pays the lesser of (a) the unitrust percentage or (b) actual net income. Protects the trust if the initial illiquid asset doesn't generate cash flow until it sells.
Net Income with Makeup CRUT (NIMCRUT): Same as NICRUT but tracks accumulated shortfalls. Once the asset sells and the trust is liquid, it makes up prior-year deficits — which can dramatically front-load payouts in later years.
Flip CRUT: Starts as a NICRUT or NIMCRUT, then "flips" to a standard CRUT upon a triggering event (sale of the initial asset, marriage, birth of a beneficiary). The most common structure for real estate and private equity donations.

The 10% remainder test — and why it constrains payout rates

IRC §664 requires that the present value of the charitable remainder — what the charity will receive at trust termination — must be at least 10% of the initial value contributed.² This test must be met at the time of funding.

The calculation uses the IRS §7520 rate — 120% of the mid-term applicable federal rate, rounded to the nearest 0.2%. For April 2026, the §7520 rate is 4.6%.³ Higher §7520 rates make the test easier to pass because future dollars are discounted less aggressively, leaving a larger present-value remainder.

What fails the test: High payout rates and older donors deplete the trust faster, leaving less for charity. Common combinations that fail:

An 8% CRAT funded by a 75-year-old — the aggressive payout rate leaves too little present-value remainder for a shorter life expectancy.
A 7% CRUT for a couple aged 50/48 — the long horizon at a high rate can squeeze the remainder below 10% when rates are moderate.

A specialist will model the §7520 rate, IRS actuarial tables, and payout rate together to find the maximum payout that keeps the trust valid — there's real money left on the table by guessing.

The charitable deduction — how it's sized

You receive an income tax deduction in the year you fund the CRT equal to the present value of the remainder interest.¹ This is calculated using the §7520 rate, the trust term (or life expectancy from IRS actuarial tables), and the payout rate.

Rough rule of thumb for a CRUT funded at age 65, 5% payout rate, April 2026 §7520 rate of 4.6%, 20-year term: the charitable deduction is approximately 35–45% of the initial contribution value. Longer terms, higher payout rates, and lower §7520 rates reduce the deduction; shorter terms, lower payouts, and higher rates increase it.

The deduction is generally subject to a 30% of AGI limit for appreciated capital gain property contributed to a CRT naming a public charity as remainder beneficiary, with unused deduction carrying forward 5 years.⁴

2026 OBBBA changes for top-bracket donors: For donors in the 37% marginal bracket, the charitable deduction is effectively valued at 35% rather than 37% — your $400,000 deduction generates $140,000 of tax benefit instead of $148,000.⁵ A 0.5% AGI floor also applies but has minimal impact on large CRT deductions. Neither provision changes the fundamental math of capital gains avoidance, which is the primary driver.

How capital gains flow through a CRT

When the CRT sells appreciated assets inside the trust, no capital gains tax is owed at that moment — the CRT is a tax-exempt entity under IRC §664.² However, gains are tracked and flow to beneficiaries as distributions occur using a four-tier system:

Tier 1: Ordinary income. Current-year trust earnings (dividends, interest) distribute first.
Tier 2: Capital gains. Short-term, then long-term gains — including capital gains from the initial asset sale — distribute next, taxed at your 2026 LTCG rates (0%/15%/20% depending on income).
Tier 3: Other income. Tax-exempt income, if any.
Tier 4: Return of principal. Untaxed.

The practical implication: you don't escape capital gains — you defer and spread them. If the CRT holds the proceeds for 20 years and distributes $100,000/year, the embedded capital gains distribute as tier 2 income across the payout period, often during retirement when your marginal rate is lower than your peak-earning years. The deferral benefit is real even though the gain ultimately faces tax.

Why deferral beats selling today: At current rates, deferring a $1M capital gain for 20 years and distributing it across that period is dramatically more valuable than paying 23.8% ($238,000) in year one and investing the remainder. The CRT keeps that $238,000 invested and compounding for the full term — at 6% annual growth, that's over $700,000 in additional value from the deferred tax alone.

Who should seriously consider a CRT

A CRT makes the most sense when several factors align:

Large, highly appreciated asset ($500K+). The capital gains avoidance is the primary driver. Below $500K, setup and trustee costs eat a significant fraction of the benefit. Above $1M, the economics become compelling.
Need for income. The income stream is the quid pro quo — you're giving up the asset's full estate value in exchange for annual payouts. If you don't need income, a DAF is simpler and the charity receives more.
Charitable intent. The remainder goes to charity (or a DAF). If your primary goal is wealth transfer to heirs, a CRT is the wrong structure — though some advisors pair a CRT with a "wealth replacement" irrevocable life insurance trust (ILIT) to restore the estate value.
Long time horizon. The deferred-compounding benefit grows over time. A 60-year-old funding a 20-year CRUT captures far more tax-deferred growth than a 75-year-old with a 10-year term.
Real estate or illiquid assets. Donors with highly appreciated real estate can contribute it to a Flip CRUT before selling. The trust waits for the sale, then converts to a standard unitrust payout. This is one of the highest-impact CRT strategies available to real estate owners.

CRT vs Donor-Advised Fund — when to choose each

	CRT	DAF
Do you receive income from it?	Yes — for life or term	No
Practical minimum asset size	$500K+	$5,000 at major custodians
Setup complexity	High — attorney required, trustee needed, annual Form 5227	Simple — online account opening
Charitable deduction	Partial (present value of remainder only)	Full FMV of contributed assets
Capital gains on contribution	Deferred — distributed over payout period	Avoided entirely (charity sells tax-free)
Control over charitable grants	Remainder beneficiary named at creation (or name a DAF)	Full flexibility to grant to any 501(c)(3) over time
Can add assets over time?	Yes (CRUT only)	Yes, unlimited contributions
Estate impact	Removes asset from estate; consider wealth replacement trust	Removes asset from estate

Common combination: Fund a DAF with appreciated stock for the immediate full deduction and charitable flexibility; use a CRT for the assets where you also want an income stream and are comfortable with the complexity. A specialist will model both against your cash flow needs and tax situation simultaneously.

Setup process and ongoing requirements

Attorney drafts the trust document. Must comply with IRC §664 requirements. The IRS publishes sample forms (Rev. Proc. 2005-52 through 2005-59) that attorneys use as a foundation. Expect $2,000–$5,000 in legal fees for a straightforward single-life CRUT.
Trustee selection. In most states, the donor can serve as trustee of their own CRUT. Many advisors recommend a corporate trustee (bank trust department, trust company) for compliance management. Corporate trustee fees are typically 0.5–1.0% of trust assets annually.
Asset transfer and appraisal. For publicly traded securities, transfer is straightforward — a broker-to-broker in-kind transfer. For real estate or private assets, a qualified appraisal (Form 8283, Section B) is required before contribution, not after.⁶
Annual Form 5227. The CRT files an IRS information return each year reporting trust income, the tier allocation of distributions, and compliance with §664. Most trust administrators include this in their fee.
Annual revaluation (CRUT only). Each year, trust assets must be valued to calculate the next year's payout. For publicly traded securities, straightforward. For illiquid assets, an annual qualified appraisal may be required — a significant ongoing cost to factor in.

Common mistakes with CRTs

Funding too small. A $200,000 CRT pays $10,000–$14,000/year before taxes and requires the same setup and ongoing compliance as a $2M CRT. The economics rarely justify it below $500K.
Setting the payout rate too high. A 9% or 10% CRUT can fail the 10% remainder test, particularly for younger donors or in low-rate environments. A specialist finds the maximum valid payout.
Funding with the wrong asset. Short-term appreciated assets (held under one year) produce only a cost-basis deduction, not FMV. S-corporation stock and retirement account assets carry significant complications. Identify the right asset before initiating any transfer.
Ignoring state income tax. CRT payouts are ordinary income and capital gains — taxable at the state level. California (13.3%), New York (10.9%), and Minnesota (9.85%) donors should model the state drag. Some structures explore trustee siting in no-income-tax states.
Not naming a backup charitable beneficiary. If your named charity changes status or closes, the trust needs a valid 501(c)(3) remainder beneficiary to stay qualified. Many attorneys recommend naming a DAF as backup — which preserves the donor's flexibility to redirect grants if needed.
Missing the qualified appraisal deadline. For non-publicly-traded property, the appraisal must be conducted no earlier than 60 days before contribution and no later than the tax return due date.⁶ Appraisals dated after the contribution don't qualify.

When to use the calculator vs. when to call an advisor

The CRT income and legacy calculator gives you a directional sense of payout, deduction, and capital gains comparison for publicly traded securities. Use it as a starting point. A specialist becomes essential when:

Your asset is real estate, closely held stock, or a partnership interest.
You're evaluating a Flip CRUT structure for a pre-sale real estate strategy.
You want to model CRT income against Social Security and other retirement income to understand marginal bracket effects over time.
You're considering a wealth replacement ILIT alongside the CRT.
Your payout needs, spouse's life expectancy, state of domicile, and charitable goals all need to be modeled simultaneously — which is almost always the case.
