When a home held in an irrevocable trust is sold, federal capital gains tax is owed by either the grantor personally or the trust itself, depending on how the trust is classified for income tax purposes. That single classification question drives the entire bill, because trusts hit the top 20% capital gains rate once their income passes $16,250 in 2026, while an individual does not reach that rate until taxable income clears $549,450. The taxes on the sale of a home in an irrevocable trust can therefore range from nothing at all to roughly 23.8% of the gain at the federal level, depending on three things: whether the trust is a grantor or non-grantor trust, how the home’s cost basis was set, and whether the proceeds stay inside the trust or get distributed to beneficiaries.
Who the Taxpayer Is
Every irrevocable trust is either a grantor trust or a non-grantor trust, and the IRS treats them very differently.
In a grantor trust, the grantor retained enough control or benefit that the trust is disregarded for income tax purposes. All items of income, deduction, and credit flow through to the grantor’s personal return.1Office of the Law Revision Counsel. 26 USC 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners The trust files an informational return but owes no tax. The grantor reports the home sale on Schedule D of Form 1040 and pays at individual rates.
A non-grantor trust is its own taxpayer. The trustee obtains an EIN, files Form 1041, and the trust pays capital gains tax at its own compressed brackets. If the trust document allows it, the trustee can push the gain out to beneficiaries, who then report it on their personal returns at their own rates. That shift is often the difference between a 20% federal rate and a 15% or even 0% rate.
How the Taxable Gain Is Figured
The gain is the sale price minus the home’s adjusted basis. How that basis was set when the home entered the trust is usually the biggest number in the calculation.
Lifetime Transfer: Carryover Basis
When the grantor transferred the home into the trust during life, the trust took the grantor’s original cost basis.2Office of the Law Revision Counsel. 26 USC 1015 – Basis of Property Acquired by Gifts and Transfers in Trust A home bought thirty years ago for $150,000 still has a $150,000 starting basis in the trust, no matter what it’s worth today. Capital improvements made before or after the transfer, such as a new roof, remodeled kitchen, or HVAC replacement, add to that basis, but routine repairs do not.3Internal Revenue Service. Selling Your Home The trustee bears the burden of proving improvements, so receipts matter.
Transfer at Death: Stepped-Up Basis, With a Trap
Property passing from a decedent generally gets a basis reset to fair market value on the date of death.4Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent A $150,000 home worth $500,000 at the grantor’s death would get a $500,000 basis, erasing decades of appreciation if sold soon after.
The trap: in Revenue Ruling 2023-2, the IRS concluded that assets held in an irrevocable grantor trust do not get a stepped-up basis at the grantor’s death if those assets were not included in the grantor’s taxable estate.5Internal Revenue Service. Internal Revenue Bulletin 2023-16 Many irrevocable trusts are built precisely to keep assets out of the estate for estate-tax reasons, and that same design denies the step-up. Families expecting the basis to reset at death can be blindsided. If the trust was structured so the home remains in the estate, the step-up still applies.
Depreciation Recapture if the Home Was Ever Rented
If depreciation was ever claimed on the home as a rental, the portion of the gain tied to that depreciation is taxed at a flat 25% as unrecaptured Section 1250 gain, regardless of bracket. Recapture is computed before the rest of the gain is taxed at capital gains rates. Even a short stretch of rental use adds a meaningful line to the bill.
The $250,000/$500,000 Home Sale Exclusion
The Section 121 exclusion lets a seller exclude up to $250,000 of gain, or $500,000 for a married couple filing jointly, on a principal residence.6Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence In the trust context, it works only in narrow circumstances.
If the trust is a grantor trust and the grantor personally meets the ownership and use tests, the exclusion is available. The grantor must have owned the home (through the trust) and lived in it as a primary residence for at least two of the five years before the sale. Because a grantor trust is disregarded for income tax purposes, the IRS has treated the grantor as the owner for Section 121 purposes.7Internal Revenue Service. Private Letter Ruling 199912026 The grantor claims the exclusion on the personal return.
If the grantor moved into a nursing home or assisted-living facility, the use clock does not necessarily stop. A grantor who is physically or mentally unable to care for themselves and lived in the home for at least one year during the five-year window can count time in a licensed care facility toward the two-year use requirement.6Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence A partial exclusion may apply if health reasons forced a move before the full two years were met.
Non-grantor trusts cannot use the exclusion at all. The taxpayer is the trust, and a trust cannot occupy a home as a principal residence. The entire gain is taxable, which is why distributing the proceeds to beneficiaries matters so much for these trusts.
Why the Rate Gap Is So Large
For 2026, trust and estate capital gains brackets are compressed to the point of near-irrelevance:8Internal Revenue Service. Revenue Procedure 2025-32
- 0% on taxable income up to $3,300
- 15% on taxable income from $3,300 to $16,250
- 20% on taxable income above $16,250
A $200,000 gain retained in a trust hits the 20% ceiling almost instantly. The same gain on an individual’s return stays at 15% until taxable income exceeds $549,450 for a single filer or $613,700 for joint filers. For a grantor trust, this gap never comes up: the gain lands on the grantor’s Form 1040 and is taxed at the grantor’s own rate.9Internal Revenue Service. Topic No. 409, Capital Gains and Losses
The 3.8% Net Investment Income Tax
A separate 3.8% surtax can sit on top of the capital gains tax. For a trust, it applies to the lesser of the trust’s undistributed net investment income or the amount by which adjusted gross income exceeds the threshold where the top ordinary bracket starts.10Office of the Law Revision Counsel. 26 USC 1411 – Imposition of Tax For 2026, that threshold is $16,000.8Internal Revenue Service. Revenue Procedure 2025-32 Virtually any trust-level gain from a home sale will clear it.
A trust retaining a $300,000 gain would pay roughly $10,800 of NIIT on top of regular capital gains tax, bringing the combined federal rate close to 23.8%. Two things cut the surtax. Gain excluded under Section 121 is not net investment income.11Internal Revenue Service. Questions and Answers on the Net Investment Income Tax And distributing the gain to beneficiaries removes it from the trust’s undistributed income; the beneficiaries face the NIIT only if their own income clears $200,000 single or $250,000 joint.
Pushing the Gain to Beneficiaries
For a non-grantor trust, distributing sale proceeds to beneficiaries is usually the single most effective way to lower the overall tax bill. Capital gains are normally trapped at the trust level, but the Code allows gains to be included in distributable net income when they are actually paid, credited, or required to be distributed to beneficiaries during the tax year, with the allocation permitted by the trust document or state law.12Office of the Law Revision Counsel. 26 USC 643 – Definitions Applicable to Subparts A, B, C, and D The beneficiaries then report the gain on their personal returns at their own rates.
Timing is where trustees get caught. A home that closes in November or December may leave no time to distribute before year-end. The 65-day rule gives the trustee a safety valve: a distribution made in the first 65 days of the following year can be treated as if it were made on the last day of the prior year.13eCFR. 26 CFR 1.663(b)-1 – Distributions in First 65 Days of Taxable Year The election is made by checking a box on Form 1041 by the return’s due date, and it is irrevocable for that year. Missing the window leaves the gain stranded in the trust at compressed rates.
Estimated Tax, Filing, and the Gift Tax Return
A six-figure gain almost always creates an estimated tax obligation. A trust that expects to owe $1,000 or more in tax after credits must pay quarterly, with 2026 deadlines of April 15, June 15, September 15, and January 15, 2027.14Internal Revenue Service. 2026 Form 1041-ES Estimated Income Tax for Estates and Trusts The safe harbor is 90% of the current year or 100% of the prior year (110% if prior-year AGI exceeded $150,000). A trust with little or no prior income can easily skip the payment because there was no prior liability to anchor the estimate; the trustee should remit for the quarter in which the sale closes.
Filing follows classification. A grantor trust usually attaches a statement to Form 1041, and the grantor reports the sale on Schedule D of Form 1040; no K-1 is issued.15Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 (2025) A non-grantor trust reports the sale on Schedule D of Form 1041, claims an income distribution deduction for any gain pushed out, and issues each beneficiary a Schedule K-1.16Internal Revenue Service. 2025 Instructions for Schedule D (Form 1041) Form 1041 is due April 15 for calendar-year trusts.
One loose end from the original transfer can still matter at sale time. Moving a home into an irrevocable trust during life is a completed gift for federal gift tax purposes, and if the value exceeded the annual exclusion ($19,000 per recipient for 2026), a Form 709 was required.17Internal Revenue Service. What’s New – Estate and Gift Tax Filing it rarely produces an actual gift tax bill because the excess is applied against the lifetime exemption, but the return starts the IRS’s limitations clock on challenging the valuation and locks in the carryover basis the trust uses now. If no Form 709 was filed at the time, the IRS has no time limit to audit the unreported gift, and that is worth cleaning up with a tax professional before closing.18Internal Revenue Service. Instructions for Form 709 (2025)
