Unitrust: Tax Benefits, Payout Rules, and NICRUT/NIMCRUT Variants

A charitable remainder unitrust, or CRUT, is an irrevocable trust you fund with assets that then pays you (or another income beneficiary) a fixed percentage of the trust’s value each year, recalculated annually, for life or for a term of up to 20 years. Whatever remains at the end goes to a charity you name. Because the trust itself is generally exempt from federal income tax, contributed assets can be sold and reinvested without an immediate capital gains bill, and you claim a charitable income tax deduction upfront for the projected value of the eventual gift to charity.

How the Annual Payment Works

A CRUT has four moving parts: the donor who funds it, one or more income beneficiaries who receive the payments, a trustee who manages the assets, and a charitable remainder beneficiary that must qualify under Internal Revenue Code Section 170(c).

Each year the trustee appraises the trust’s net fair market value and multiplies it by the fixed percentage written into the trust document. Say the payout rate is 6% and the trust is worth $1,000,000 on the valuation date. The distribution that year is $60,000. If the portfolio grows to $1,100,000 the following year, the payment rises to $66,000. If it drops to $900,000, the payment falls to $54,000. The beneficiary shares in both the gains and the losses.

This is the defining difference between a CRUT and a charitable remainder annuity trust (CRAT). A CRAT locks in a dollar amount at inception and pays the same figure every year no matter what the investments do. A CRUT tracks the trust’s actual value.

Tax Benefits of Funding a CRUT

Upfront Income Tax Deduction

When you fund the trust, you get a charitable deduction equal to the present value of the remainder interest projected to reach charity. The IRS calculates that figure using actuarial tables and the Section 7520 rate, which for early 2026 is 4.6%.¹ A higher 7520 rate produces a larger deduction; a younger beneficiary or a higher payout rate produces a smaller one, because more of the trust’s value is expected to be paid out as income rather than left for charity.

The deduction is capped by adjusted gross income. Contributions of long-term appreciated property are generally limited to 30% of AGI; cash contributions have a higher ceiling. Unused amounts carry forward for up to five years.²

Capital Gains on Appreciated Assets

The CRUT’s biggest edge shows up when you hold something with a large embedded gain: appreciated stock, real estate, a concentrated position. Sell it yourself and you owe capital gains tax on the appreciation. Contribute it to the CRUT instead, and the trust can sell it without triggering an immediate tax hit, because the trust is tax-exempt.³ The full sale proceeds stay inside the trust and get reinvested. The gain doesn’t vanish — it comes back to you gradually through the distribution ordering rules — but spreading that tax over many years is a real financial advantage compared with paying it all in year one.

Tax-Exempt Growth Inside the Trust

A properly structured CRUT pays no federal income tax on interest, dividends, or realized gains earned inside the trust.³ Over a 20-year term, that compounding difference can materially increase both the income paid out and the amount reaching charity.

Estate Tax

If you name yourself as income beneficiary, the trust’s value is included in your gross estate under Section 2036(a) because you retained an income interest. But the present value of the charitable remainder qualifies for the estate tax charitable deduction under Section 2055.⁴ If you are the sole income beneficiary, the full trust value effectively drops out of your taxable estate. If a successor beneficiary continues the income stream, the value of that continuing interest remains subject to estate tax.

How Your Distributions Are Taxed

The trust doesn’t pay income tax, but you do on what you receive. Every distribution is characterized under a strict four-tier ordering system, with the highest-taxed income coming out first:³

Tier 1, ordinary income: interest, dividends, and rents from the current and prior years, taxed as ordinary income.
Tier 2, capital gains: current and accumulated capital gains, taxed at capital gains rates. This is where the gain on contributed appreciated property lives.
Tier 3, other income: tax-exempt and other miscellaneous categories.
Tier 4, corpus: a tax-free return of principal, reached only after the first three tiers are exhausted.

The practical takeaway: if you funded the trust with appreciated stock the trustee then sold, expect your early distributions to carry ordinary income treatment, followed by capital gains treatment as Tier 1 runs down. Tier 4 tax-free treatment is possible in later years but not the norm during the middle of the trust’s life.

Legal Requirements the Trust Must Meet

Miss any of these and the trust is not a valid CRUT. The tax-exempt status and your charitable deduction both disappear.

Payout Rate Between 5% and 50%

The fixed percentage must be at least 5% and no more than 50% of the trust’s annually revalued net fair market value.⁵ Most CRUTs land between 5% and 8%. Push much higher and the 10% remainder test starts to bite.

The 10% Remainder Test

At the time of each contribution, the present value of the charitable remainder must equal at least 10% of the net fair market value of what you contribute.³ The calculation uses the 7520 rate, the beneficiary’s age, and the payout percentage. A high payout, a young beneficiary, or a low 7520 rate can each drop the projected remainder below 10% and disqualify the trust. The math has to work before funding, not after.

Duration

Payments run for the life or lives of the named individual beneficiaries, or for a fixed term of up to 20 years.⁵ Combining a life interest with a term of years is not allowed.

Irrevocability

A CRUT is irrevocable the moment it is created and funded.⁵ You cannot pull the assets back or swap in a non-charitable remainder beneficiary. That certainty is what makes the upfront deduction valid.

Variations for Illiquid Assets

The standard CRUT works well with marketable securities. When the contribution is real estate, a closely held business interest, or something else that generates little cash, three variations solve the distribution problem.

Net Income Unitrust (NICRUT)

A NICRUT caps the annual payment at the lesser of the stated unitrust percentage or the trust’s actual net income. If the trust document says 6% but the trust earns only 3%, the beneficiary gets the 3% figure. The shortfall is lost — there is no catch-up. This keeps the trustee from having to fire-sale an illiquid asset just to meet a distribution.

Net Income With Makeup Unitrust (NIMCRUT)

A NIMCRUT behaves the same way in lean years but tracks the cumulative shortfall. In later years when income exceeds the unitrust percentage, the trustee uses the excess to pay down the accumulated deficit. That fits donors who contribute a non-income-producing asset but expect higher income later, once the asset is sold or converted.

Flip Unitrust

The flip unitrust bridges the gap. It starts as a NICRUT or NIMCRUT while the illiquid asset is inside, then permanently converts to a standard fixed-percentage CRUT after a specified triggering event. The trigger must be identified in the document and cannot be within anyone’s discretion. Permissible triggers include the sale of an unmarketable asset or a life event such as marriage, divorce, birth, or death.⁶ Any makeup deficit accumulated during the NIMCRUT phase is forfeited at the flip.

Adding Assets After Funding

Unlike a CRAT, a CRUT accepts additional contributions after the initial funding. Each new contribution enlarges the asset base and, by extension, next year’s distribution. But every additional contribution must independently satisfy the 10% remainder test as of its own contribution date.³ Contributions of unmarketable property such as real estate or closely held stock require a qualified independent appraisal when the donor serves as trustee.

Two Traps to Design Around

Self-Dealing

For self-dealing purposes, the IRS treats a CRUT like a private foundation. Section 4947(a)(2) applies the Section 4941 self-dealing rules to charitable remainder trusts.⁷ “Disqualified persons” include the donor, the income beneficiaries, family members of either, and entities they control. They cannot sell or lease property to the trust, borrow from it, provide it goods or services, or use its assets personally. The annual unitrust payments themselves are the one carve-out. Penalties begin at a 10% excise tax on the disqualified person and 5% on a knowingly participating trustee, and climb sharply if the transaction is not corrected within the taxable period.⁸

Unrelated Business Taxable Income

If the trust earns unrelated business taxable income (UBTI), it owes a 100% excise tax on that income.³ That is not a misprint. UBTI most often shows up when the trust holds debt-financed property or invests in a partnership that runs an active business. Contributing mortgaged real estate is the classic mistake — the debt turns part of the income and any gain on sale into UBTI. Screen assets carefully before funding.

Ongoing Administration

The trustee handles three recurring tasks. First, an annual valuation on the same date each year, using market prices for securities and a qualified independent appraisal for real estate or business interests. Second, calculating and paying the distribution — the annual value multiplied by the fixed unitrust percentage, paid at least annually and potentially quarterly or monthly if the document says so. Third, tax reporting: Form 5227 (Split-Interest Trust Information Return) reporting income, deductions, distributions, and the remainder’s actuarial value,⁹ Form 1041-A each year,¹⁰ and a Schedule K-1 to each income beneficiary showing the four-tier character of that year’s distributions.
