A charitable remainder unitrust is an irrevocable trust you fund with cash or appreciated assets, draw an annual income from for life or up to 20 years, and leave to a charity you choose when the income period ends. Each year the trustee revalues the trust and pays you a fixed percentage of that value, so your income rises when investments do well and falls when they don’t. In exchange for the eventual gift to charity, you get an immediate income tax deduction, you avoid an upfront capital gains hit on anything appreciated you contribute, and the trust’s investments grow free of federal income tax while they’re inside the trust.
How the Annual Payment Works
Four roles make the trust function. You are the donor who contributes the assets and signs the trust into existence. One or more income beneficiaries, often you and a spouse, receive the yearly payments. A trustee manages the investments, values the assets, and sends the distributions. A charitable remainder beneficiary, which must qualify under Internal Revenue Code Section 170(c), takes whatever is left when the income term ends.
The defining mechanic is annual revaluation. Each year the trustee appraises the trust’s net fair market value and multiplies it by the fixed percentage written into the trust document. If the trust specifies a 6% payout and the assets are worth $1,000,000, you receive $60,000 that year. Grow the portfolio to $1,100,000 and the next payment is $66,000. Lose ground to $900,000 and the payment drops to $54,000. You share in both the gains and the losses.
That is the difference between a unitrust and a charitable remainder annuity trust. A CRAT fixes the dollar payment at inception and pays the same amount every year regardless of how the investments perform. A unitrust ties your income to the trust’s actual value year by year.
Tax Benefits You Get Upfront
Income Tax Deduction
When you fund the trust, you receive a charitable income tax deduction equal to the present value of what will eventually pass to charity. The IRS calculates that figure using actuarial tables and the Section 7520 interest rate in effect when you fund.1Internal Revenue Service. Rev. Rul. 2026-7 A higher 7520 rate pushes the projected remainder up, which gives you a bigger deduction. Younger beneficiaries and higher payout percentages work the other way, because more of the trust’s value is projected to flow out as income rather than to charity.
The deduction is subject to adjusted gross income limits. Long-term appreciated property is generally capped at 30% of AGI; cash contributions carry a higher ceiling. Any deduction you can’t use in the contribution year carries forward for up to five years.2Internal Revenue Service. Charitable Contribution Deductions
Deferring Capital Gains on Appreciated Assets
This is the piece that matters most if you’re holding stock, real estate, or other property with large embedded gains. Sell those assets yourself and you owe capital gains tax on the appreciation right away. Contribute them to the trust instead and the trust can sell them without paying any immediate capital gains tax, because the trust itself is tax-exempt.3Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts The full sale proceeds stay in the trust and get reinvested rather than being shaved down by a tax bill. The gain doesn’t vanish; it passes through to you gradually inside your distributions under the ordering rules described below. But spreading that tax across many years instead of paying it all in the year of sale is a real advantage.
Tax-Exempt Growth Inside the Trust
A properly structured unitrust pays no federal income tax on dividends, interest, or realized gains while the money sits inside the trust.3Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts Over a 20-year or lifetime term, compounding without an annual tax drag can meaningfully increase both the income you draw and the remainder that reaches charity.
Estate Tax Treatment
If you name yourself as the income beneficiary, the trust’s value is included in your gross estate under Section 2036(a) because you kept an income interest. The present value of the charitable remainder qualifies for the estate tax charitable deduction under Section 2055, so the net estate tax impact is usually limited to the value of any successor beneficiary’s interest.4Office of the Law Revision Counsel. 26 USC 2055 – Transfers for Public, Charitable, and Religious Uses If you’re the only income beneficiary, with no spouse or child continuing the stream after you, the full trust value qualifies for the deduction and effectively drops out of your taxable estate.
How Your Distributions Are Taxed
The trust itself owes no tax. You do, on what you receive. Each distribution is characterized under a strict four-tier ordering system that pays out the highest-taxed income first:3Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts
- Tier 1, ordinary income. Payments are treated as ordinary income (interest, dividends, rents) to the extent the trust has current-year and accumulated ordinary income on hand.
- Tier 2, capital gains. Once ordinary income is exhausted, further payments carry capital gains character from the trust’s current and prior years.
- Tier 3, other income. Tax-exempt income and other miscellaneous categories come next, after capital gains are used up.
- Tier 4, return of principal. Only after all three income categories are depleted do payments represent a tax-free return of corpus.
If you contributed appreciated stock that the trust sold, the resulting capital gains sit in Tier 2 and get allocated into your checks after the trust’s ordinary income runs out. Tier 4 is rare in the early and middle years of a trust that is earning anything at all.
Legal Requirements the Trust Must Meet
Several structural rules have to be satisfied for the trust to qualify. Miss any of them and the trust isn’t a valid charitable remainder unitrust, which means the tax benefits go away.
Payout Percentage
The fixed percentage must be at least 5% and no more than 50% of the trust’s annually revalued net fair market value.5Internal Revenue Service. About Charitable Remainder Trusts Most trusts land between 5% and 8% in practice. Push the rate much higher and you tend to collide with the 10% remainder test.
The 10% Remainder Test
At the time of each contribution, the present value of the charitable remainder must equal at least 10% of the fair market value of what you’re putting in.3Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts The calculation uses the Section 7520 rate, the beneficiary’s age and life expectancy, and the stated 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 you fund.
Duration
Income payments can run for the life or lives of the named beneficiaries, or for a fixed term of up to 20 years.5Internal Revenue Service. About Charitable Remainder Trusts Combining the two, a life interest followed by a term of years, is not allowed.
Irrevocability
The trust must be irrevocable from the moment it is created and funded.5Internal Revenue Service. About Charitable Remainder Trusts You can’t take the assets back, swap the charitable beneficiary for a non-charity, or undo the trust. That certainty is what makes the charitable deduction valid.
One flexibility worth noting: unlike a CRAT, a unitrust lets you add assets after the initial funding. Every additional contribution has to independently pass the 10% remainder test on its own contribution date.3Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts If you contribute unmarketable property and act as your own trustee, the IRS requires a qualified independent appraisal.
Variations for Illiquid Assets
The standard unitrust works well when the trust holds marketable investments. If you’re contributing real estate, a closely held business interest, or anything that doesn’t throw off much cash, three variations handle the problem.
Net Income Unitrust (NICRUT)
A NICRUT limits the annual payment to the lesser of the stated percentage or the trust’s actual net income. If the trust document calls for 6% but the trust only earns 3%, you receive the 3% amount. The shortfall is simply lost. This keeps the trustee from being forced to dump an illiquid asset at a discount just to make a payment.
Net Income With Makeup Unitrust (NIMCRUT)
A NIMCRUT acts like a NICRUT in lean years but tracks the cumulative shortfall. When the trust later earns more than the stated percentage, the trustee can use the excess to pay down the accumulated deficit. This fits donors contributing an asset that doesn’t produce income now but is expected to generate higher income after a planned sale or conversion.
Flip Unitrust
A flip unitrust is built for the handoff from an illiquid asset to a diversified portfolio. It begins as a NICRUT or NIMCRUT while holding the hard-to-sell asset, then permanently converts to a standard fixed-percentage unitrust after a specified triggering event. The trust document must name the trigger, and it cannot be something the trustee or anyone else controls at discretion. Permissible triggers include the sale of an unmarketable asset or a life event such as a marriage, divorce, birth, or death. Once the flip takes effect, any makeup deficit from the NIMCRUT phase is forfeited.6Internal Revenue Service. 26 CFR 1.664-3 – Charitable Remainder Unitrusts
Traps That Can Wipe Out the Benefits
Unrelated Business Taxable Income
If the trust earns unrelated business taxable income, it owes a 100% excise tax on that income.3Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts Not a typo. The trust keeps none of the UBTI. The usual culprits are debt-financed property and certain partnership interests that generate active business income. Contributing a mortgaged property is the classic trap: the debt makes a portion of both the income and any gain on sale into UBTI. Clean up the asset before you contribute it, or don’t contribute it.
Self-Dealing
The IRS treats a unitrust like a private foundation for self-dealing purposes. Under Section 4947(a)(2), the self-dealing rules of Section 4941 apply.7Office of the Law Revision Counsel. 26 USC 4947 – Application of Taxes to Certain Nonexempt Trusts A “disqualified person” includes the donor, the income beneficiaries, family members of either, and any entity they control. Prohibited transactions include selling or leasing property to the trust, borrowing from it, furnishing goods or services to it, or using trust assets for personal benefit. Excise taxes on the disqualified person start at 10% of the amount involved and can escalate to 200% if the transaction isn’t corrected.8Office of the Law Revision Counsel. 26 U.S. Code 4941 – Taxes on Self-Dealing The one carve-out is the annual unitrust payment itself, which is the whole point of the structure.
Ongoing Administration
The trustee appraises the assets on the same date each year, typically the first day of the trust’s tax year. Marketable securities use closing prices; real estate or business interests require a qualified independent appraisal. That figure sets the next distribution.
Payments must go out at least annually, though the trust document can specify quarterly or monthly installments. The trustee is personally responsible for getting them out on time.
On the reporting side, the trustee files IRS Form 5227, the Split-Interest Trust Information Return, each year, reporting income, deductions, distributions, and the actuarial value of the charitable remainder.9Internal Revenue Service. About Form 5227, Split-Interest Trust Information Return Form 1041-A is also required each year because the trust is a split-interest trust described in Section 4947(a)(2), not just in years the trust accumulates charitable amounts.10eCFR. 26 CFR 1.6034-1 – Information Returns Required of Trusts Each income beneficiary receives a Schedule K-1 showing the character of their distributions under the four-tier rules, which they’ll need to finish their own return.
