Irrevocable Trust

An Irrevocable Trust in the United States creates a fiduciary arrangement under which a trustee holds and distributes assets for the beneficiaries.

The primary federal statute governing the estate tax treatment of irrevocable trusts is the Internal Revenue Code (IRC), administered by the Internal Revenue Service (IRS). IRC § 2038 provides that assets subject to the grantor's retained power to alter, amend, revoke, or terminate are included in the grantor's taxable estate at death. By transferring assets to a properly drafted irrevocable trust — and relinquishing those retained powers — the grantor removes the transferred assets from their gross estate under IRC §§ 2036, 2037, and 2038. The federal estate tax exemption stands at $15 million per individual for 2026 after the One Big Beautiful Bill Act of 2025 made the higher Tax Cuts and Jobs Act exemption permanent and eliminated the scheduled post-2025 sunset, with annual inflation adjustments thereafter, keeping irrevocable trust planning central for high-net-worth individuals.

The income taxation of irrevocable trusts depends on whether the trust is classified as a grantor trust under IRC §§ 671–679 (the grantor trust rules) or a non-grantor trust that files its own Form 1041 tax return. In a grantor trust — where the grantor retains certain powers such as the power to substitute assets under IRC § 675(4) — all trust income, deductions, and credits are attributed to the grantor for income tax purposes, effectively making the grantor's payment of income tax on trust earnings a tax-free gift to the beneficiaries.

Common irrevocable trust structures include the Irrevocable Life Insurance Trust (ILIT), which removes life insurance death benefits from the taxable estate; the Spousal Lifetime Access Trust (SLAT), which provides the grantor's spouse with access to trust distributions while removing assets from the estate; the Grantor Retained Annuity Trust (GRAT), which transfers appreciation to beneficiaries using the IRC § 7520 rate to minimize gift tax; the Qualified Personal Residence Trust (QPRT), governed by Treasury Regulation § 25.2702-5, which transfers the grantor's personal residence to beneficiaries at a discounted gift tax value; and the Supplemental Needs Trust (SNT), also called a Special Needs Trust, which holds assets for a disabled beneficiary without disqualifying them from Medicaid or Supplemental Security Income (SSI) under 42 U.S.C. § 1396p.

The Uniform Trust Code (UTC), promulgated by the Uniform Law Commission in 2000 and adopted in modified form in over 30 states, provides the default framework for trust administration in adopting states, covering trustee duties, beneficiary rights, trust modification, and trust termination procedures. The Uniform Prudent Investor Act (UPIA), adopted in all 50 states, governs the investment standard for trustees managing trust assets — requiring total-return investing under modern portfolio theory, diversification, and impartiality between income beneficiaries and remainder beneficiaries.

A US Irrevocable Trust is needed whenever an individual or couple has accumulated assets above the applicable federal estate tax exemption and seeks to reduce estate tax exposure, or when asset protection from future creditors, long-term care costs, or professional liability claims is a primary goal.

High-net-worth individuals and families working with estate planning attorneys at firms serving clients in New York, California, Florida, and Texas use Irrevocable Life Insurance Trusts (ILITs) to hold life insurance policies with death benefits that would otherwise be included in the taxable estate under IRC § 2042. By having the ILIT purchase or own the policy — rather than the insured — the death proceeds pass income-tax-free to the trust and estate-tax-free to the beneficiaries, often providing liquidity to pay estate taxes on illiquid assets like closely held businesses or real estate.

Business owners with significant equity in S corporations, limited liability companies, or family limited partnerships use Grantor Retained Annuity Trusts (GRATs) structured under IRC § 2702 and Treasury Regulation § 25.2702-3 to transfer appreciation above the IRC § 7520 hurdle rate to heirs with little or no gift tax. A zeroed-out GRAT — where the annuity is set so that the remainder value is near zero for gift tax purposes — allows all appreciation above the § 7520 rate to pass to beneficiaries tax-free if the grantor survives the GRAT term.

Married couples with assets that one spouse wishes to give away — but still wants indirect access to — use Spousal Lifetime Access Trusts (SLATs). By funding a SLAT, the grantor removes assets from their taxable estate while the beneficiary spouse retains access to trust distributions for health, education, maintenance, and support (HEMS) purposes. The reciprocal trust doctrine under IRC § 2036 must be avoided by ensuring that two SLATs created by spouses are not identical in structure.

Parents of children or adults with disabilities who receive means-tested government benefits including Medicaid and SSI use Supplemental Needs Trusts funded with the grantor's assets (a third-party SNT) or with the beneficiary's own personal injury settlement proceeds (a self-settled SNT under 42 U.S.C. § 1396p(d)(4)(A)) to preserve benefit eligibility while improving quality of life.

Individuals concerned about long-term care costs and Medicaid eligibility use Medicaid Asset Protection Trusts (MAPTs) — which must be irrevocable and funded at least five years before the Medicaid application under the five-year look-back period — to transfer assets while preserving Medicaid eligibility for nursing home care costs that average $90,000 to $110,000 annually.

A legally effective US Irrevocable Trust must contain the following essential provisions to achieve its estate planning, asset protection, and tax objectives under the Internal Revenue Code, the Uniform Trust Code, and applicable state trust law.

The grantor and trustee identification clause must name the grantor (the person creating the trust and transferring assets), the initial trustee (who may not be the grantor for estate tax purposes in most irrevocable trust structures), and successor trustees to take over if the initial trustee resigns, dies, or becomes incapacitated. Corporate trustees — national trust companies such as Northern Trust, Bessemer Trust, or U.S. Trust (Bank of America Private Bank) — are often used for large irrevocable trusts to confirm professional administration and continuity.

The trust purpose and beneficiary designation clause must identify the current income beneficiaries (who receive trust distributions during their lifetimes) and the remainder beneficiaries (who receive the trust assets after the income beneficiaries' deaths). The trust must clearly state whether the trustee has discretionary authority to make distributions (a discretionary trust) or whether distributions are governed by an ascertainable standard (a support trust that distributes for health, education, maintenance, and support — HEMS — which is the standard under IRC §§ 2041 and 2514 that avoids a general power of appointment).

The trustee powers clause must enumerate the trustee's investment and management powers — including the power to invest in stocks, bonds, real estate, alternative investments, and closely held business interests; the power to make loans; the power to sell and exchange trust assets; and the power to retain closely held business interests. The trustee's investment duties are governed by the Uniform Prudent Investor Act, which requires total-return portfolio management using modern portfolio theory and mandates diversification unless the trustee determines it is not in the trust's best interests.

The spendthrift clause protects the trust assets from the beneficiaries' creditors by prohibiting the voluntary or involuntary transfer of a beneficiary's interest before distribution. Under the UTC and most state trust laws, a valid spendthrift clause prevents a beneficiary's creditors from attaching or garnishing the trust assets before they are actually distributed. Most states recognize the self-settled spendthrift trust (also called a Domestic Asset Protection Trust, or DAPT) as effective against the settlor's own future creditors — with the strongest asset protection in states including Alaska, Delaware, Nevada, South Dakota, and Wyoming.

The trust protector provision — increasingly standard in sophisticated irrevocable trust drafting — appoints an independent third party (the trust protector) with specific powers to modify the trust in response to changes in tax law, family circumstances, or unanticipated events. Trust protector powers may include the power to amend the trust to comply with changes in the IRC, to add or remove beneficiaries, to change the governing law, or to grant or limit the trustee's powers.

The termination clause must specify the conditions under which the trust terminates — typically upon the death of the last income beneficiary, upon the trust assets falling below a minimum threshold, or at a specified date — and how the remaining assets are distributed to the remainder beneficiaries or their estates upon termination.
