Charitable remainder trust analysis: how it works, who it fits, and the catch

How a charitable remainder trust works

1. You sign an irrevocable trust agreement naming yourself (and often a spouse) as income beneficiary and one or more charities as remainder beneficiaries.
2. You transfer the appreciated asset, such as land, a building, or company stock, to the trust before any binding sale.
3. The trustee sells. Because a charitable remainder trust is exempt from income tax (IRC 664(c)), the full sale price stays invested.
4. The trust pays you each year for your life, joint lives, or a term of up to 20 years.
5. At the end, the remaining assets go to charity, often your own donor-advised fund or a family foundation.

You get an income tax deduction in the year of transfer for the present value of the charity's remainder, figured with the IRC 7520 rate. That rate was 5.6% for October 2026 (Rev. Rul. 2026-19), and you may use the rate for the month of the gift or either of the two prior months. For a CRAT, a higher rate means a larger deduction; for a unitrust the rate matters much less.

CRAT, CRUT, NIMCRUT and flip trusts

The 10% test: the charity's remainder must be worth at least 10% of the value placed in the trust (IRC 664(d)(1)(D), (d)(2)(D)). High payout rates, long terms and young beneficiaries can fail it. The 5% probability test applies to CRATs: if there is more than a 5% chance the fixed payments exhaust the trust while a beneficiary is alive, no deduction is allowed (Rev. Rul. 77-374). Rev. Proc. 2016-42 offers a sample early-termination clause that avoids that test.

Timing: transfer before a binding sale

The trust saves tax on the sale only if the trust, not you, is the seller. If the sale has effectively happened before the transfer, the IRS taxes the gain to you under the assignment of income doctrine, and the trust then holds after-tax cash.

• Respected: In Palmer v. Commissioner, 62 T.C. 684 (1974), a gift of stock followed by a redemption the next day was respected because the charity was not legally bound to redeem. In Rev. Rul. 78-197 the IRS said it will treat such proceeds as the donor's income only if the donee is legally bound, or can be compelled, to sell.
• Not respected: In Blake v. Commissioner, 697 F.2d 473 (2d Cir. 1982), a prearranged understanding about how the charity would use the proceeds led to the gain being taxed to the donor. In Ferguson v. Commissioner, 174 F.3d 997 (9th Cir. 1999), stock given after a merger and tender offer had "ripened" left the gain with the donors.

In practice: fund the trust before signing a binding purchase agreement, before a deal has become practically certain, and never with a trust agreement that obligates the trustee to sell to a particular buyer. A non-binding letter of intent is less risky than a signed contract, but the earlier the better. Get a qualified appraisal for non-cash gifts over $5,000.

How the payments are taxed: the four tiers

Each payment you receive carries out the trust's income in a fixed order (IRC 664(b)):

1. Ordinary income (interest, non-qualified dividends), current and past undistributed.
2. Capital gain, current and past undistributed, including the gain from selling your asset.
3. Other income, such as tax-exempt interest.
4. Return of principal, which is not taxed.

Within each tier, the highest-taxed category comes out first (Treas. Reg. 1.664-1(d)). So the big gain from the sale sits in tier 2 and is taxed to you a slice at a time over many years, often at lower brackets than one lump. The trust files Form 5227 every year and sends you a K-1. Unrelated business taxable income inside the trust is hit with a 100% excise tax (IRC 664(c)(2)), which is one reason debt-financed property and operating businesses are poor assets for these trusts.

Worked example

Assumptions (illustrative): married couple filing jointly in California, $150,000 of other income, 2026 tax tables. They own land worth $2,000,000 with a $200,000 basis (gain $1,800,000), no debt. Tax figures are from the Big Sale Tax engine.

The trust starts with about $627,000 more working for the family. What it gives up is the asset itself: heirs receive nothing from the trust unless the plan sets aside other assets for them.

IRS stance and audit risk

Properly drafted charitable remainder trusts are long-established and the IRS publishes sample forms. Audit risk concentrates on:

• Prearranged sales (above).
• Valuation: unmarketable assets need an independent trustee or a qualified appraisal (Treas. Reg. 1.664-1(a)(7)).
• Self-dealing: the private foundation rules apply through IRC 4947(a)(2), so you and your family cannot buy from, sell to, or borrow from the trust.
• Mortgaged property: debt can cause bargain-sale income, grantor trust problems and unrelated business income. Pay it off first.
• S corporation stock: a charitable remainder trust is not an eligible shareholder, so a transfer would end the S election.
• The CRAT listed transaction: final regulations published July 9, 2026 (T.D. 10051) identify as a listed transaction a CRAT whose trustee uses the sale proceeds to buy a commercial annuity while the beneficiary reports the payments as annuity income instead of under the four tiers. Participants and material advisors must disclose, and penalties apply. A normal CRAT is not affected.

Costs, fees and the deduction limits

Expect attorney fees to draft the trust, a qualified appraisal for non-cash assets, annual trustee and investment fees, and annual Form 5227 preparation. The 2026 deduction rules also matter:

• Gifts of appreciated long-term property with a public charity remainder are deductible up to 30% of adjusted gross income; if a private foundation can be the remainder beneficiary, the limit is 20% and the deduction is generally based on your cost basis. Unused amounts carry forward five years.
• Starting in 2026, charitable deductions count only above 0.5% of your contribution base (IRC 170(b)(1)), and taxpayers in the 37% bracket have itemized deductions reduced by 2/37 (IRC 68), which caps their value at about 35 cents per dollar.

How it compares with a Section 453 installment sale

Both spread the tax on a large gain over years. An installment sale does it with a buyer's note; you keep all the value, your heirs inherit the unpaid note, and you carry the buyer's credit risk, protected by the collateral and note terms. A charitable remainder trust does it inside a tax-exempt trust; you get a deduction and a diversified portfolio, but the remainder belongs to charity. Recapture taxed as ordinary income also differs: an installment sale reports Section 1245 recapture in the year of sale, while in a trust it lands in tier 1 of your payments. If you are not charitable, the installment sale usually wins. If you are, compare a charitable lead trust, a bargain sale or donating appreciated assets to a donor-advised fund too.
