A charitable remainder unitrust pays no federal income tax at the trust level, but that exemption is only the first layer of the picture. How a CRUT is taxed depends on three separate things happening at once: the trust itself is exempt under Internal Revenue Code Section 664, the beneficiary owes tax on each annual payout under a strict four-tier ordering system that pushes the worst-taxed income out first, and the donor claims a limited charitable deduction on the front end that is capped by adjusted gross income.1Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts Miss any one of those layers and the planning math falls apart.
Tax at the Trust Level
Under IRC 664(c), a qualified CRUT is exempt from federal income tax.1Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts Interest, dividends, and capital gains earned inside the trust generate no tax bill for the trust itself. That is why funding a CRUT with appreciated stock or real estate is such a common move: the trustee can sell the position and reinvest the entire proceeds without a capital gains hit at the point of sale. The gain does not vanish. It gets tracked by category and pushed out to the beneficiary over time through the tier system described below.
There is one exception large enough to sink the trust. If the CRUT has any unrelated business taxable income in a given year, the trust owes an excise tax equal to 100% of that UBTI.1Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts Every dollar of UBTI is taxed away completely. The most common source is debt-financed income: property acquired with borrowed money is generally treated as generating UBTI under IRC 514.2Internal Revenue Service. Unrelated Business Income From Debt-Financed Property Under IRC Section 514 Contributing mortgaged real estate or letting the trust run leverage is where donors get burned.
The Four-Tier Distribution System
The trust is exempt. The beneficiary is not. Each annual payout is characterized under an ordering system set out in the IRS’s CRT guidance, and the trust must track cumulative income by category across every year it has existed.3Internal Revenue Service. Charitable Remainder Trusts The rule is worst-first: distributions are deemed to come out in the order that maximizes the beneficiary’s tax.
Tier 1: Ordinary Income
The payout is first treated as ordinary income to the extent the trust has any accumulated ordinary income from the current year or any prior year. This includes interest and non-qualified dividends. It is taxed at the beneficiary’s marginal rate, up to 37% at the top federal bracket. Only after every dollar of accumulated ordinary income has been distributed does the allocation move to the next tier.
Tier 2: Capital Gains
Once ordinary income is exhausted, the payout draws from accumulated capital gains. Within this tier, short-term gains come out before long-term gains, so the beneficiary sees the higher-taxed portion first. Long-term gains keep their preferential 0%, 15%, or 20% rate depending on the beneficiary’s income.3Internal Revenue Service. Charitable Remainder Trusts This is where the gain from selling contributed appreciated assets sits. The trust recognized nothing when it sold the stock, but the gain is parked in Tier 2 and worked down over years of unitrust payments.
Tier 3: Tax-Exempt Income
The third tier is tax-exempt income earned by the trust, such as interest on municipal bonds. Distributions sourced from this tier are generally free from federal income tax. A payout reaches Tier 3 only after the beneficiary has been deemed to receive every dollar of accumulated ordinary income and capital gains.
Tier 4: Return of Principal
The final tier is a return of trust corpus. Distributions here are not taxable. For an actively invested trust holding productive assets, payouts rarely reach this tier during the early years, because Tiers 1 and 2 keep refilling.
The trustee reports the character and amount of each year’s distribution on a Schedule K-1, which the beneficiary uses to prepare a personal return.4Internal Revenue Service. Instructions for Form 5227
Appreciated Assets and the Deferral Effect
The four-tier system is what makes the CRUT useful for concentrated appreciated positions. Sell a $1 million stock position with a $100,000 basis outright, and $900,000 of gain hits the current year’s return. Contribute that same stock to a CRUT, and the trust sells it tax-free and reinvests the full $1 million.1Office of the Law Revision Counsel. 26 USC 664 – Charitable Remainder Trusts The $900,000 enters Tier 2 and gets released to the beneficiary as capital gain across the trust’s term rather than in a single tax year.
Valuation matters for both the deduction and the tier-tracking. Publicly traded securities use market prices on the transfer date. Real estate and closely held stock need a qualified independent appraisal. Any noncash contribution deducted above $500 requires Form 8283, and property valued above $5,000 requires the appraisal summary in Section B, with the full appraisal attached in some cases.5Internal Revenue Service. Form 8283 – Noncash Charitable Contributions
The Donor’s Charitable Income Tax Deduction
Funding a CRUT produces an immediate charitable deduction, but only for the present value of the remainder interest the charity is projected to receive after the trust term ends. Not the full contribution. Three inputs drive the calculation: the unitrust payout rate, the trust term or the beneficiary’s life expectancy, and the Section 7520 rate the IRS publishes monthly.6Internal Revenue Service. Section 7520 Interest Rates
A higher Section 7520 rate produces a larger deduction, because the IRS assumes faster growth and therefore more left over for charity. The donor can elect to use the rate from the month of contribution or from either of the two preceding months, whichever gives the best result.7GovInfo. 26 CFR 20.7520-2 – Valuation of Annuities, Unitrust Interests, and Remainder Interests The Section 7520 rate has hovered between 4.6% and 4.8% in early 2026.6Internal Revenue Service. Section 7520 Interest Rates
AGI Limits and Carryover
The deduction is capped by the standard AGI limits for charitable contributions. For appreciated capital gain property given to a public charity, the cap is 30% of AGI. That is the limit most CRUT donors hit, because most CRUTs are funded with appreciated stock or real estate. Cash contributions to a public charity get the higher 60% AGI cap.8Office of the Law Revision Counsel. 26 USC 170 – Charitable, Etc., Contributions and Gifts If the remainder is going to a private non-operating foundation, the cap drops to 20%.
Anything you cannot use in the contribution year carries forward for up to five additional tax years.9eCFR. 26 CFR 1.170A-10 – Charitable Contributions Carryovers of Individuals For a large gift, the carryforward is usually necessary. A $2 million contribution generating a $600,000 deduction cannot land in a single return if AGI is only $500,000.
Net Investment Income Tax
Distributions falling in Tiers 1 through 3 can also pick up the 3.8% Net Investment Income Tax under IRC 1411. The surtax applies to individuals with modified AGI above $200,000 (single) or $250,000 (married filing jointly). CRUT payouts are investment-character income, so they count toward the calculation. It is easy to miss during planning because the four-tier system already dominates the analysis.
Gift and Estate Tax Treatment
Funding a CRUT generally does not create a taxable gift on the charitable portion, because the remainder interest passing to charity qualifies for the unlimited charitable gift tax deduction. If you name someone other than yourself or your spouse as an income beneficiary, though, the present value of that income interest is a taxable gift. It can be offset by the lifetime gift and estate tax exemption.
If you retain a life income interest, the full fair market value of the trust assets is included in your gross estate under IRC 2036.10eCFR. 26 CFR 20.2036-1 – Transfers With Retained Life Estate An offsetting estate tax charitable deduction is allowed for the present value of the remainder passing to charity, so only the value of any income interest still owed to other beneficiaries is actually exposed to estate tax. If you are not an income beneficiary at all, the trust assets sit outside your taxable estate.
Self-Dealing Excise Taxes
CRUTs are subject to the private foundation self-dealing rules under IRC 4941, applied through IRC 4947(a)(2).11Internal Revenue Service. Self-Dealing and Other Tax Issues Involving Charitable Remainder Trusts These rules levy excise taxes on transactions between the trust and “disqualified persons,” a group that includes the donor, family members, and entities they control.
Prohibited transactions include selling or exchanging property between the trust and a disqualified person, lending money between them, and furnishing goods or services in either direction outside narrow exceptions.12Internal Revenue Service. Private Foundations – Self-Dealing IRC 4941(d)(1)(c) The penalties apply even if the transaction happened at fair market value. A donor-trustee who rents trust-owned property to themselves has triggered self-dealing regardless of the rent charged. This is one of the main reasons planners recommend an independent trustee, or at minimum legal review of any transaction touching a connected party.
Annual Filings That Drive the Tax Result
The trustee files Form 5227 (Split-Interest Trust Information Return) each year. For a calendar-year trust, the deadline is April 15 of the following year; if the trust terminates mid-year, the final return is due by the 15th day of the fourth month after termination.4Internal Revenue Service. Instructions for Form 5227
Each income beneficiary also receives a Schedule K-1 showing the amount and character of the year’s distribution, broken out by tier so it can be reported correctly on a personal return.4Internal Revenue Service. Instructions for Form 5227 Errors in tier allocation, or failure to carry accumulated income categories forward year over year, are where CRUT tax compliance most often goes wrong.
