When a home held in an irrevocable trust is sold, the capital gains tax is owed by the grantor, the trust itself, or the beneficiaries, and which one depends on how the trust is classified for income tax purposes and whether the sale proceeds are distributed. Taxes on the sale of a home in an irrevocable trust turn on three questions: is the trust a grantor trust or a non-grantor trust, what is the home’s cost basis, and can the gain be shifted to individuals who face lower rates than the trust does. Getting these wrong can cost tens of thousands of dollars, because trusts hit the top federal capital gains bracket at just $16,250 of income in 2026.
Who Actually Pays the Tax
Every irrevocable trust is either a grantor trust or a non-grantor trust, and that single classification decides the taxpayer.
In a grantor trust, the grantor retained enough control or benefit that the IRS disregards the trust for income tax purposes. All income, deductions, and credits 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 may file, but it owes no tax. The grantor reports the home sale on Schedule D of their Form 1040 at their own individual rates.2Internal Revenue Service. Topic No. 409, Capital Gains and Losses
A non-grantor trust is a separate taxpayer with its own EIN and its own Form 1041. The trust owes the capital gains tax on the sale, unless the trustee distributes the gain to beneficiaries in the same tax year, in which case the tax follows the money to the beneficiaries’ individual returns. Whether that shift is even permitted depends on the trust document and state law, discussed further below.
How the Taxable Gain Is Calculated
The capital gain is the sale price minus the home’s adjusted basis. Basis depends on how the home got into the trust.
Lifetime Transfer: Carryover Basis
When a grantor moves a home into an irrevocable trust while alive, the trust takes the grantor’s original cost basis.3Office 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 has a $150,000 basis in the trust, no matter what it’s worth now.
Capital improvements add to that basis. A new roof, an added bathroom, a kitchen remodel, or a new HVAC system all qualify. Routine repairs generally do not, unless they were part of a larger renovation.4Internal Revenue Service. Selling Your Home The trustee needs receipts and contractor records; the burden of proving a higher basis falls on the trust if the IRS asks.
Transfer at Death: Stepped-Up Basis (Sometimes)
Property passing from a decedent generally gets a basis reset to fair market value on the date of death.5Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent A home purchased for $150,000 that is worth $500,000 at the grantor’s death gets a new basis of $500,000. Sell soon after and the taxable gain can be close to zero.
There is a significant trap. In Revenue Ruling 2023-2, the IRS concluded that assets held in an irrevocable grantor trust do not receive a stepped-up basis at the grantor’s death if those assets are not included in the grantor’s taxable estate.6Internal Revenue Service. Internal Revenue Bulletin 2023-16 Many irrevocable trusts are deliberately designed to sit outside the estate to avoid estate tax. The same design leaves the old carryover basis in place when the grantor dies. Families who assumed the basis would reset can face a large, unexpected capital gains tax on sale. If the trust was structured so the home remains in the grantor’s estate, the step-up still applies.
Can the $250,000 / $500,000 Home Sale Exclusion Apply?
Section 121 lets a homeowner exclude up to $250,000 of gain from the sale of a main home, or $500,000 for a married couple filing jointly.7Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence Whether an irrevocable trust can use it depends entirely on classification.
Grantor trusts can qualify. Because the trust is disregarded for income tax purposes, the IRS treats the grantor as the owner of the residence for the Section 121 ownership test.8Internal Revenue Service. Private Letter Ruling 199912026 If the grantor owned the home through the trust and lived in it as their principal residence for at least two of the five years before the sale, the exclusion goes on the grantor’s personal return.
There is a care-facility softener. If the grantor becomes physically or mentally unable to care for themselves and lived in the home for at least one year of the five-year window, time spent in a licensed care facility while still owning the home counts toward the two-year use requirement.7Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence A prorated exclusion may be available if the grantor moved out for health reasons and still fell short.
Non-grantor trusts cannot use the exclusion at all. A trust cannot occupy a house as a principal residence, and the statute requires the taxpayer to have lived there. The full gain is taxable, which is why moving the gain out to beneficiaries matters so much for these trusts.
Why the Rate Is So Much Higher Inside the Trust
Trust income brackets are compressed. For 2026, the trust capital gains brackets are:9Internal 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
By contrast, an individual filer does not reach the 20% capital gains rate until taxable income tops $549,450 (single) or $613,700 (married filing jointly). A $200,000 gain retained inside the trust blows past the 20% threshold almost immediately. That same gain on a beneficiary’s return would often be taxed at 15%, sometimes 0%.
The 3.8% Net Investment Income Tax
A separate 3.8% surtax stacks on top. For trusts, the Net Investment Income Tax applies to the lesser of undistributed net investment income or the amount by which the trust’s 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 just $16,000.9Internal Revenue Service. Revenue Procedure 2025-32 Nearly any home-sale gain a trust retains will trigger it. Combined with the 20% capital gains rate, the effective federal rate on retained trust gain can reach 23.8%.
Two things blunt the NIIT. Any gain excluded under Section 121 is not net investment income to begin with.11Internal Revenue Service. Questions and Answers on the Net Investment Income Tax And distributing the gain out of the trust removes it from the trust’s undistributed net investment income. Beneficiaries may owe NIIT themselves, but their thresholds are far higher: $200,000 for single filers and $250,000 for joint filers.
Shifting the Gain to Beneficiaries
For non-grantor trusts, the most valuable planning lever is distributing the sale proceeds to beneficiaries so the gain is taxed on their returns instead of the trust’s.
Capital gains are ordinarily excluded from a trust’s distributable net income and taxed at the trust level. The exception: when capital gains are actually paid, credited, or required to be distributed to beneficiaries during the tax year, they can be included in distributable net income and taxed to the beneficiaries.12Office of the Law Revision Counsel. 26 USC 643 – Definitions Applicable to Subparts A, B, C, and D The trust document or applicable state law must allocate the gains to beneficiaries; not every trust permits this.
Timing is the practical problem. A home that closes late in the year may not leave the trustee time to distribute before December 31. The 65-day rule solves this. A trustee can make a distribution within the first 65 days of the following year and elect to treat it as made on the last day of the prior tax 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, is due by the return’s due date, is irrevocable for that year, and has to be renewed annually. Miss the window, and the gain stays trapped inside the trust at compressed rates. December sales are where this most often goes wrong.
Distribution to beneficiaries is reported through Schedule K-1. The trust claims an income distribution deduction on Form 1041, and each beneficiary picks up their share on their own return.14Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 (2025)
Estimated Tax on the Sale
A home sale usually creates an estimated tax obligation. A trust must make quarterly payments if it expects to owe $1,000 or more after credits and withholding.15Internal Revenue Service. 2026 Form 1041-ES Estimated Income Tax for Estates and Trusts For calendar-year trusts in 2026, the deadlines are April 15, June 15, September 15, and January 15, 2027.
The safe harbor is 90% of the current year’s tax or 100% of the prior year’s tax, whichever is smaller. If the trust’s prior-year adjusted gross income was above $150,000, the prior-year figure rises to 110%. A trust that had little income in prior years and suddenly sells a home for a six-figure gain can get caught here: there is no prior-year liability to anchor to, so the trustee should compute and remit the estimated payment for the quarter the sale closes.
Which Return Reports the Sale
For a grantor trust, the trust does not file a conventional income tax return on the sale. The trustee typically attaches a statement to Form 1041 showing income and deductions, and the grantor reports the sale on Schedule D of Form 1040.14Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 (2025) No K-1 to the grantor.
For a non-grantor trust, the trustee reports the sale on Schedule D of Form 1041.16Internal Revenue Service. 2025 Instructions for Schedule D (Form 1041) If the gain is distributed, the trust claims the distribution deduction and issues K-1s to the beneficiaries, who report their shares on their own returns.
