A trust does not automatically avoid capital gains tax. Whether a trust reduces or eliminates the tax depends on three things: the type of trust, whether the gains stay inside the trust or get distributed to beneficiaries, and whether the assets qualify for a stepped-up basis when the grantor dies. Some structures do nothing for capital gains during life. Others can wipe out decades of appreciation at death. One particular structure, the charitable remainder trust, can sidestep the tax on a sale entirely.
Revocable Trusts Do Not Reduce Capital Gains Tax During Your Lifetime
A revocable trust, often called a living trust, offers no capital gains tax savings while the grantor is alive. The IRS treats it as a grantor trust, which means the person who created it is still considered the owner of everything inside for income tax purposes.1IRS. Trust Primer The trust files no separate return. Any capital gain from selling an asset held in the trust goes on the grantor’s personal Form 1040 and is taxed at the grantor’s individual rate.
Transferring an appreciated asset into a revocable trust is not itself a taxable event. You are moving property to yourself in the eyes of the IRS, so there is no sale and no gain. The asset keeps its original cost basis. The capital-gains payoff from a revocable trust comes later, at death, through the basis step-up discussed below.
Irrevocable Trusts Pay Their Own Tax, and the Brackets Are Brutal
An irrevocable trust is a separate taxpayer. Once you transfer assets in, the trust files Form 1041.2Internal Revenue Service. About Form 1041, U.S. Income Tax Return for Estates and Trusts If the trust keeps the gain from a sale, the trust owes the tax, and that is where things get expensive fast.
Trust tax brackets are heavily compressed. For 2026, the ordinary income rates are:
- 10% on taxable income up to $3,300
- 24% from $3,301 to $11,700
- 35% from $11,701 to $16,000
- 37% above $16,000
The top 20% long-term capital gains rate hits at just $16,250 of trust income for 2026.3Internal Revenue Service. 2026 Form 1041-ES Estimated Income Tax for Estates and Trusts A single individual does not reach that same 20% rate until taxable income exceeds roughly $518,900. A trust gets there almost immediately.
On top of that, the 3.8% Net Investment Income Tax applies at the trust level once income passes the dollar amount where the top ordinary bracket begins — the same $16,000 threshold for 2026.4Office of the Law Revision Counsel. 26 U.S.C. 1411 – Imposition of Tax For individuals, NIIT does not kick in until $200,000 (single) or $250,000 (joint). A trust holding a sizable long-term gain can therefore end up paying 23.8% on every dollar above about $16,000.5Internal Revenue Service. Topic No. 559, Net Investment Income Tax
Distributing Gains to Beneficiaries Usually Lowers the Bill
When an irrevocable trust distributes income, it takes a deduction and passes the character of the income out to beneficiaries on Schedule K-1.2Internal Revenue Service. About Form 1041, U.S. Income Tax Return for Estates and Trusts Each beneficiary then reports their share on a personal return and pays at individual rates, which for most people are far lower than the trust’s compressed brackets. Distributing gains also reduces or eliminates the trust-level NIIT, since the surtax at the trust level only reaches undistributed investment income. Trustees who automatically accumulate gains inside the trust often give up substantial tax savings.
The Step-Up in Basis Is the Real Way Trusts Erase Capital Gains
The most powerful capital-gains benefit any trust offers is not a clever distribution strategy. It is the step-up in basis at death. Under federal law, when someone dies, the cost basis of most assets they owned resets to fair market value on the date of death.6Office of the Law Revision Counsel. 26 U.S.C. 1014 – Basis of Property Acquired From a Decedent All the appreciation that built up during the owner’s lifetime disappears for tax purposes.
If someone bought stock for $50,000 and it was worth $400,000 at death, the heirs inherit it with a $400,000 basis. Sell it the next week for $400,000 and the capital gains tax on the $350,000 of lifetime appreciation is zero.
Revocable Trusts Qualify for the Step-Up
Assets in a revocable trust get the full basis adjustment because the tax code treats property in a revocable trust as property acquired from the decedent.6Office of the Law Revision Counsel. 26 U.S.C. 1014 – Basis of Property Acquired From a Decedent The trust’s assets are included in the grantor’s gross estate, and beneficiaries who inherit through the trust receive the stepped-up basis. This is the main capital-gains purpose of a revocable trust: not avoiding tax during life, but erasing unrealized gains at death.
Many Irrevocable Trusts Do Not
In 2023 the IRS issued Revenue Ruling 2023-2, which addressed this directly. Assets in an irrevocable grantor trust do not get a step-up in basis at the grantor’s death if those assets are not included in the grantor’s gross estate for estate tax purposes.7IRS. Bulletin No. 2023-16, Revenue Ruling 2023-2 The basis stays exactly what it was before death.
An irrevocable trust can still qualify for the step-up if the grantor kept certain powers that pull the assets back into the taxable estate. Some irrevocable trusts are designed to do exactly that. Trusts specifically structured to remove assets from the estate for estate tax savings generally will not. The tradeoff is real. Keeping assets out of the estate may save estate tax, but it locks in the original basis and sets up larger capital gains whenever the assets are eventually sold.
Charitable Remainder Trusts Can Avoid Tax on the Sale Itself
A charitable remainder trust (CRT) is one of the few structures that genuinely avoids capital gains tax on a sale. A CRT is exempt from income tax in any year it operates properly.8Office of the Law Revision Counsel. 26 U.S.C. 664 – Charitable Remainder Trusts If you transfer appreciated stock or real estate into a CRT and the trust sells it, no capital gains tax is owed on the sale. The full proceeds stay invested and generate income.
The tax is not gone forever. As the CRT pays income out to you or other non-charitable beneficiaries, those distributions carry the character of the trust’s underlying income under a set ordering rule, so capital gains eventually flow out and get taxed on beneficiary returns.8Office of the Law Revision Counsel. 26 U.S.C. 664 – Charitable Remainder Trusts The practical effect is deferral and spreading of the tax over many years rather than outright elimination. When the trust ends, whatever remains goes to the named charity. CRTs fit best when you hold a highly appreciated asset, want ongoing income, and intend to leave the remainder to charity.
Home Sales Held in a Trust
If your principal residence sits in a grantor trust, including a revocable living trust, you can still claim the Section 121 home sale exclusion. Treasury regulations treat a taxpayer who is considered the owner of a trust under the grantor trust rules as the owner of the residence for the two-year ownership requirement, and the trust’s sale is treated as the taxpayer’s own.9eCFR. 26 CFR 1.121-1 – Exclusion of Gain From Sale or Exchange of a Principal Residence You can exclude up to $250,000 of gain, or $500,000 for married couples filing jointly, just as if you owned the house outright.
The answer changes once the home sits in an irrevocable non-grantor trust. The beneficiary is not treated as owner for income tax purposes, so the Section 121 exclusion generally does not apply, and the trust itself cannot claim it because the trust is not an individual using the property as a principal residence. If a home might be sold after the grantor’s death, trust structure can decide whether hundreds of thousands of dollars of gain are excludable or fully taxable.
