An irrevocable trust is a good idea in a narrow set of situations: your estate is large enough to face federal estate tax, you work in a profession with serious liability exposure, you’re planning ahead for Medicaid, or you’re providing for a beneficiary with a disability. For most other families, the loss of control, the ongoing costs, and the lost step-up in basis outweigh what you’d gain. The federal estate and gift tax exemption rose to $15 million per individual in 2026, which pulls far fewer households into the group that benefits from this tool.
Who Actually Benefits
Three situations consistently justify the permanence of an irrevocable trust. If none of them describe you, a simpler plan probably fits better.
Your Estate Exceeds the Federal Exemption
For 2026, the federal estate and gift tax exemption is $15 million per individual, or $30 million for a married couple. Amounts above that threshold face a 40% federal estate tax.1Internal Revenue Service. Whats New – Estate and Gift Tax The $15 million figure comes from the One Big Beautiful Bill Act, signed July 4, 2025, which permanently increased the exemption and indexed it for inflation starting in 2027.2Office of the Law Revision Counsel. 26 USC 2010 – Unified Credit Against Estate Tax The generation-skipping transfer tax exemption matches at $15 million, which matters if you want wealth to flow to grandchildren or later generations.3Congress.gov. The Generation-Skipping Transfer Tax
Transferring assets into an irrevocable trust removes them from your taxable estate. Because you no longer own the property, its value doesn’t count when you die. Moving the assets in counts as a completed gift: if the value transferred to any one person in a year exceeds $19,000 (the 2026 annual gift tax exclusion), you file IRS Form 709, and the excess chips away at your $15 million lifetime exemption rather than triggering an immediate tax bill.4Internal Revenue Service.

You Face Real Creditor or Liability Risk
Because you no longer legally own assets inside an irrevocable trust, your personal creditors generally cannot reach them. Lawsuits, judgments, and bankruptcy proceedings target what you own, and trust assets fall outside that scope. Physicians, business owners, and others in high-liability professions often set up an irrevocable trust primarily for this reason.
Protection has limits. Transfers made to dodge existing creditors can be clawed back as fraudulent conveyances, so you need to fund the trust while you’re financially healthy and before any claims arise. Last-minute asset shuffling draws court skepticism.
You’re Planning for Medicaid or Special Needs
Transferring assets into an irrevocable trust can reduce countable assets for Medicaid eligibility, which matters because Medicaid is the primary payer for nursing home care. Federal law imposes a 60-month look-back window during which Medicaid reviews asset transfers; transfers made within that period can trigger a penalty that delays eligibility.5Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Five years of advance planning is the baseline. Waiting until a health crisis hits usually means the look-back hasn’t expired and the transfer creates more problems than it solves.
A special needs trust (sometimes called a supplemental needs trust) supports a beneficiary with a disability without disqualifying them from Medicaid or Supplemental Security Income. Federal law exempts these trusts from the usual rules that count trust assets against eligibility, provided the beneficiary is disabled and the state is named as a remainder beneficiary to recover Medicaid costs after the beneficiary’s death.5Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets The trust supplements government benefits rather than replacing them, with the trustee paying vendors directly for things like recreation, education, and travel.
What You Permanently Give Up
The defining feature of an irrevocable trust is permanence. Once you fund it, you cannot take the assets back, change the terms, or dissolve the arrangement without the beneficiaries’ agreement or a court order.6Internal Revenue Service. Abusive Trust Tax Evasion Schemes – Questions and Answers The trust becomes its own legal entity. You no longer own the assets, which means you cannot sell, mortgage, or directly benefit from them unless the trust terms specifically allow it.
That control loss is real, and it’s not the only tradeoff. The one that catches most people by surprise is the step-up in basis.
Losing the Step-Up in Basis
Normally, when someone dies and leaves property to heirs, the tax basis resets to fair market value at the date of death. If you bought stock for $50,000 and it’s worth $500,000 when you die, your heirs inherit it with a $500,000 basis. They can sell immediately and owe zero capital gains tax. That reset applies to property included in your gross estate.7Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent
Assets in an irrevocable trust are removed from your gross estate by design. They generally don’t qualify for the step-up. Your beneficiaries inherit your original cost basis and owe capital gains tax on the full appreciation when they sell. In the example above, they’d owe tax on $450,000 of gains instead of nothing.
This is why irrevocable trusts work best for assets that aren’t expected to appreciate dramatically, or for estates large enough that the 40% estate tax savings outweigh the capital gains tax on the lost step-up. For someone whose estate falls comfortably below $15 million, transferring highly appreciated assets into an irrevocable trust can actually increase the family’s total tax burden. The math is worth running with an estate planning attorney before you sign anything.
Compressed Trust Income Tax Brackets
Irrevocable trusts that retain income pay federal income tax at rates that compress quickly. In 2026, a trust hits the top 37% federal rate at just $16,000 of taxable income. An individual filer doesn’t reach that same rate until $640,600.8Internal Revenue Service. Rev Proc 2025-32 Trusts with undistributed investment income above $16,000 may also owe the 3.8% net investment income tax.9Fidelity. Trusts and Taxes
Trusts can sidestep the compressed brackets by distributing income to beneficiaries, who then pay at their own individual rates. Many trust documents give the trustee discretion over whether to distribute or accumulate for exactly this reason.
What It Costs Each Year
An irrevocable trust costs more than a revocable trust to create and significantly more to maintain. Drafting fees typically run $2,000 to $6,000 for straightforward structures, with complex arrangements like multi-generational trusts, life insurance trusts, or special needs trusts running $5,000 to over $10,000.
Ongoing costs add up over the life of the trust:
- Corporate trustee fees typically run 0.5% to 2% of trust assets annually. An individual trustee may serve for less or for free, but you trade cost savings for professional investment management and impartiality.
- Irrevocable trusts file their own tax return (Form 1041) each year. Preparation fees generally run $500 to $5,000, depending on complexity and income sources.
- Moving real estate into the trust involves deed preparation, recording fees, and potentially title insurance updates. Recording fees vary widely by jurisdiction.
These costs run for as long as the trust exists, which could be decades. For smaller balances, annual fees can consume a meaningful percentage of the trust. A $200,000 trust paying a 1% trustee fee plus $1,500 in tax prep loses more than 1.7% annually to administration alone, and that drag compounds. Run the math on total lifetime costs before committing.
When a Revocable Trust Does the Job Instead
A revocable trust (often called a living trust) lets you keep full control over the assets, change terms at any time, and dissolve the arrangement if you want. Because you retain control, the assets stay part of your taxable estate, and creditors can still reach them. A revocable trust automatically becomes irrevocable when you die.
Both types avoid probate and keep your affairs out of public records. If probate avoidance and privacy are your only goals, a revocable trust accomplishes that without the permanence. The irrevocable version only makes sense when you need the additional benefits that come from permanently separating assets from your estate: estate tax reduction, asset protection, or eligibility planning for government benefits. For most people with estates below $15 million and no serious creditor exposure, a revocable trust handles the job.
If Your Circumstances Change Later
The name suggests you’re locked in forever, but there are ways to modify an irrevocable trust after it’s created. The most common is trust decanting: the trustee transfers assets from the existing trust into a new trust with updated terms. A majority of states have enacted decanting statutes that define when and how a trustee can do this. The trustee typically has to confirm the change serves the beneficiaries’ interests, comply with the state’s specific statute, and notify all beneficiaries. If a beneficiary objects, court approval may be required.
Courts can also modify irrevocable trusts when all beneficiaries consent and the change doesn’t defeat a material purpose of the trust. Some trust documents include a trust protector provision, giving a designated person authority to make specific changes without going to court. Building that flexibility in at the drafting stage is far easier than trying to retrofit it later. If you’re on the fence about whether an irrevocable trust fits your situation, that drafting conversation is where to raise it.
