The tax implications of putting your house in a trust depend almost entirely on one choice: whether the trust is revocable or irrevocable. A revocable trust changes nothing about your taxes during your lifetime and preserves the most valuable benefit your heirs will ever get from the property, the step-up in basis at death. An irrevocable trust is treated as a completed gift the day you record the deed, can strip away the primary residence capital gains exclusion, and usually costs your beneficiaries that step-up. For 2026, with the federal estate and gift tax exemption sitting at $15 million per person, most homeowners get more tax benefit from the revocable structure than from any estate-tax-driven irrevocable design.
Why the Revocable vs. Irrevocable Choice Drives Everything
Every tax consequence traces back to how much control you keep. A revocable living trust lets you change the terms, pull the property back, or dissolve the trust at any time. Because you never actually gave anything up, the IRS treats the arrangement as if it doesn’t exist for federal tax purposes. The Internal Revenue Code calls this a grantor trust, and all income, deductions, and tax liabilities flow through to your personal return.1Office of the Law Revision Counsel. 26 USC 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners
An irrevocable trust is different. You permanently surrender control. Once the deed is signed over, you can’t reclaim the property or rewrite the trust on your own. That surrender is what makes the trust a separate legal entity for tax purposes. The property leaves your taxable estate, but the same transfer counts as a completed gift, with its own reporting and its own downstream effects on how the home is taxed later.
Gift Tax When You Transfer the House
Moving a house into a revocable trust has no gift tax consequence. Since you can take the property back at any time, the gift is incomplete and there is nothing to report.
Transferring a home into an irrevocable trust is a completed gift equal to the property’s fair market value on the date you record the deed. You must file Form 709, the federal gift and generation-skipping transfer tax return, whether or not any tax is actually owed.2Internal Revenue Service. Instructions for Form 709
Two exemptions soften the impact. The annual gift tax exclusion lets you give up to $19,000 per recipient in 2026 without touching your lifetime exemption, though on a house worth several hundred thousand dollars that barely registers. Anything above the annual exclusion reduces your lifetime estate and gift tax exemption, which is $15 million per person for 2026.3Internal Revenue Service. What’s New – Estate and Gift Tax As long as your total lifetime gifts stay under that ceiling, no tax comes out of pocket. Amounts above it are taxed at rates up to 40%. The $15 million exemption was made permanent by the One, Big, Beautiful Bill Act and continues to adjust for inflation.
Income Tax While the Trust Owns the Home
A house in a revocable trust adds zero income tax complexity. The trust usually files no return of its own, and mortgage interest deductions, property tax deductions, and any rental income go on your personal Form 1040 exactly as they did before.1Office of the Law Revision Counsel. 26 USC 671 – Trust Income, Deductions, and Credits Attributable to Grantors and Others as Substantial Owners
A non-grantor irrevocable trust files its own Form 1041 and pays income tax on any retained income at extremely compressed brackets. For 2026, such a trust hits the top 37% federal rate at just $16,000 of taxable income.4Internal Revenue Service. 2026 Form 1041-ES Estimated Income Tax for Estates and Trusts Holding rental income or sale proceeds inside a non-grantor trust is expensive fast.
The Primary Residence Capital Gains Exclusion
Sell a home you’ve lived in for at least two of the past five years and you can exclude up to $250,000 of capital gains from tax, or $500,000 if married filing jointly.5Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence A house in a revocable trust keeps this exclusion intact because you are still the owner for income tax purposes.
A house in a non-grantor irrevocable trust can lose the exclusion entirely. The trust is the legal owner, and a trust cannot “use” a home as a principal residence. If the trust sells the property, the full gain can be taxed at those compressed trust rates.
The Intentionally Defective Grantor Trust Workaround
Estate planners often solve this by drafting an irrevocable trust that is intentionally “defective” for income tax purposes. The trust is irrevocable for estate tax, so the property is out of your estate, but is treated as a grantor trust for income tax, so you still report income on your personal return and can still claim the residence exclusion. The structure is commonly called an intentionally defective grantor trust, or IDGT. The drafting has to be precise. A trust that misses on either side can fail to achieve either goal.
Estate Tax and the Step-Up in Basis at Death
This is where the revocable-versus-irrevocable decision produces its biggest dollar consequence. When you die, a house in a revocable trust is included in your taxable estate because you never gave up control. That inclusion triggers the single most valuable benefit in estate planning: the step-up in basis.
Under federal law, property included in a decedent’s estate gets a new tax basis equal to its fair market value on the date of death.6Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent If your parents bought a home for $80,000 forty years ago and it is worth $750,000 when they die, your basis becomes $750,000. Sell it the next month for $750,000 and your capital gain is zero. Decades of appreciation vanish for tax purposes.
A house properly transferred to an irrevocable trust and kept out of the estate does not get the step-up. Your beneficiaries inherit your original cost basis, called a carryover basis. If they sell that same $750,000 house, they owe capital gains tax on $670,000 of gain. At current federal rates, that can exceed $100,000 in tax that the revocable trust structure would have eliminated. For estates well below the $15 million exemption, where no estate tax would apply anyway, giving up the step-up is usually a losing trade.
The Section 2036 Trap
Transferring your home to an irrevocable trust and continuing to live in it creates a separate problem. If you transfer property but keep the right to use or enjoy it for your lifetime, federal law pulls the full value of that property back into your taxable estate at death.7Office of the Law Revision Counsel. 26 USC 2036 – Transfers With Retained Life Estate You get the worst of both worlds. The property is back in your estate, so estate tax exposure is unchanged, but the original transfer was still a completed gift, so you have used up lifetime exemption for nothing.
The usual workaround is to pay fair market rent to the trust after the transfer. The rent has to be genuinely market-rate and carefully documented, because the IRS scrutinizes these arrangements.
Property Tax Reassessment and Transfer Taxes
The most immediate financial risk for many homeowners is not federal tax at all. Many jurisdictions cap how fast your property tax bill can grow while you own the home. A transfer that counts as a “change in ownership” under local rules can reset your assessed value to current market rates, sometimes doubling or tripling the annual bill.
Most jurisdictions exempt transfers into revocable trusts from reassessment, especially when you remain the sole beneficiary during your lifetime. Irrevocable trust transfers get more scrutiny, and whether they trigger reassessment turns on the specific state and county rules and on whether you keep a beneficial interest. Recording the new deed can also trigger local transfer taxes or documentary stamp taxes, though many jurisdictions waive these where no money changes hands. Check with your county recorder before filing.
Qualified Personal Residence Trusts
A qualified personal residence trust, or QPRT, is an irrevocable trust designed specifically to reduce the gift tax cost of transferring a home. You transfer the house into the QPRT but keep the right to live in it for a set number of years. When that retained interest term ends, the home passes to your beneficiaries.
The gift tax advantage sits in the valuation. Instead of being taxed on the home’s full fair market value, the taxable gift is reduced by the value of your retained right to live there. A longer term produces a larger discount and a smaller taxable gift.8Office of the Law Revision Counsel. 26 USC 2702 – Special Valuation Rules in Case of Transfers of Interests in Trusts Any appreciation during the term also passes to the beneficiaries free of gift and estate tax.
The catch matters. You must outlive the term. Die before it expires and the full value of the home is pulled back into your taxable estate, erasing the benefit. Once the term ends, you either move out or pay fair market rent to the beneficiaries who now own it. QPRTs suit homeowners who are healthy, expect to downsize eventually, and hold homes likely to appreciate substantially.
Your Mortgage and the Due-on-Sale Clause
Most mortgages contain a due-on-sale clause that lets the lender demand full repayment on a transfer. Federal law blocks that in most trust transfers. Under the Garn-St. Germain Depository Institutions Act, a lender cannot accelerate a mortgage on a residential property of fewer than five units when the transfer is into a trust where the borrower remains a beneficiary and occupancy does not change.9Office of the Law Revision Counsel. 12 USC 1701j-3 – Preemption of Due-on-Sale Prohibitions The typical revocable living trust fits cleanly. Many irrevocable trust transfers also fit as long as you remain a named beneficiary. Notify your lender before recording the deed to avoid administrative problems that can surface later at refinancing or on an insurance claim.
Medicaid Planning and the Five-Year Look-Back
Some homeowners put a house in an irrevocable trust specifically to qualify for Medicaid long-term care coverage. Medicaid is means-tested. A primary residence is generally exempt from the asset count, but that exemption has limits: if you enter a nursing home and your home equity exceeds your state’s threshold, or if you can no longer claim the home as your primary residence, it becomes a countable asset.
A Medicaid Asset Protection Trust, or MAPT, can move the home out of your countable assets, but timing controls everything. Federal law imposes a 60-month look-back before the date you apply for Medicaid. Assets transferred during that window are treated as if you still own them for eligibility, and the transfer creates a penalty period during which Medicaid will not cover your care. Transfer the house today and apply three years from now and the home’s value counts against you. Revocable trusts provide no Medicaid protection at all, because you still legally control the assets. Genuine surrender of control is what makes the transfer count, which means accepting the inflexibility and the loss of the step-up in basis that come with any irrevocable trust.
