What Is an Irrevocable Trust?
Last reviewed: June 2026
An irrevocable trust is a trust that — once created and funded — generally cannot be changed or revoked by the grantor. By permanently transferring assets out of your personal ownership into the trust, an irrevocable trust can provide asset protection from creditors, reduce your taxable estate, and accomplish other planning goals that a revocable trust cannot.
The trade-off is control. In exchange for these benefits, you give up the right to take assets back or change the trust terms at will. This is what makes the assets both protected and outside your estate.
Types of Irrevocable Trusts
- Irrevocable Life Insurance Trust (ILIT) — holds life insurance policies outside of the taxable estate. The death benefit passes to beneficiaries estate-tax free.
- Domestic Asset Protection Trust (DAPT) — available in about 20 states. Allows the grantor to be a discretionary beneficiary while still achieving creditor protection after a seasoning period.
- Spousal Lifetime Access Trust (SLAT) — an irrevocable trust for the benefit of a spouse, allowing the grantor to indirectly benefit from trust assets through the spouse while removing the assets from the taxable estate.
- Grantor Retained Annuity Trust (GRAT) — the grantor transfers assets to the trust and receives an annuity for a fixed term. If the assets appreciate faster than the IRS hurdle rate, the excess passes to beneficiaries estate-tax free.
- Charitable Remainder Trust (CRT) — provides income to the grantor or other beneficiaries for a period, with the remainder passing to charity.
When an Irrevocable Trust Makes Sense
Irrevocable trusts are primarily used by high-net-worth individuals whose estates may exceed the estate tax exemption — $13.61 million per person in 2026. They are also used by professionals with significant malpractice exposure who want to protect assets from future creditors.
Frequently Asked Questions
Can an irrevocable trust ever be modified?
While truly irrevocable trusts cannot be amended by the grantor unilaterally, judicial modification, trustee decanting (pouring assets into a new trust with different terms), and trust protector amendments may be available depending on state law and the trust document.
What is the difference between an irrevocable trust and a revocable trust?
A revocable trust can be changed or cancelled at any time — and provides no asset protection because you retain control. An irrevocable trust generally cannot be changed and provides asset protection and estate tax benefits because you relinquish control.
Does an irrevocable trust protect assets from all creditors?
From future creditors — yes, generally, after a seasoning period. From existing creditors — no. Transferring assets to defraud known creditors is fraudulent transfer and can be undone by a court.
Are assets in an irrevocable trust subject to estate tax?
Assets properly transferred to an irrevocable trust during the grantor's lifetime — and in excess of the annual gift tax exclusion and lifetime exemption — are generally removed from the taxable estate.
Do I need to pay income tax on irrevocable trust income?
It depends on whether the trust is a grantor trust. Many irrevocable trusts are structured as grantor trusts for income tax purposes — meaning the grantor continues to pay income taxes on trust income — while still being outside the estate for estate tax purposes.
