Some assets do not belong in an irrevocable trust, and knowing what not to put in an irrevocable trust can save you more than the trust itself was ever going to save. Retirement accounts, annuities, health savings accounts, the cash you actually live on, your primary residence in most cases, S-corporation stock, financed property, and highly appreciated assets your heirs would otherwise inherit with a stepped-up basis each carry a specific problem when they move into this kind of trust. The problems are tax hits, lost legal protections, and loss of access to assets you may still need.
The common thread is simple. An irrevocable trust permanently removes assets from your ownership and control. Some assets require individual ownership for their tax treatment to survive. Some you need to be able to reach. Some trigger a lender’s or regulator’s rights the moment they change hands. If any of those apply, a transfer creates liability that would not have existed if the asset had stayed in your name.
Retirement Accounts
Moving a traditional IRA, 401(k), or 403(b) into an irrevocable trust during your lifetime is one of the most expensive mistakes in estate planning. Federal tax law requires these accounts to be maintained for the benefit of an individual.1Office of the Law Revision Counsel. 26 U.S. Code 408 – Individual Retirement Accounts Transferring ownership to a trust causes the account to lose its tax-qualified status, and the IRS treats the full balance as a distribution in the year of the transfer. Every dollar becomes taxable income at once.
If you are under 59½, you also owe a 10% early withdrawal penalty on top of the income tax.2Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions On a $500,000 IRA, that penalty alone is $50,000 before the income tax calculation even begins. The combined hit can consume a third of the account or more.
There is no reason to put the account itself in a trust. You can name a trust as the beneficiary of your IRA or 401(k) through the plan’s beneficiary designation form. The assets pass directly to the trust at your death, no lifetime distribution, and the beneficiary designation overrides whatever your will says. If you want trust-level control over how heirs receive retirement money, the beneficiary designation is the tool.
Annuities
Annuities face a similar outcome through a different rule. When a non-natural person such as a trust holds an annuity contract, the contract loses its tax-deferred status.3Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts The annual gains inside the annuity become taxable as ordinary income every year. The whole point of owning the annuity disappears.
Narrow exceptions exist for immediate annuities and annuities held inside qualified retirement plans, but a standard deferred annuity transferred to a typical irrevocable trust loses its favorable treatment. Use the beneficiary designation instead.
Health Savings Accounts
HSAs are individual tax-advantaged accounts, like IRAs. Changing the account holder to a trust causes the account to lose its tax-exempt status and triggers a taxable distribution. The retirement account analysis applies.
Cash and Liquid Assets You Still Need
Irrevocable means irrevocable. Once you move checking account funds, savings, or short-term investments into the trust, you cannot pull them back when your car needs a new transmission or the property taxes are due. The trustee controls distributions, and the trustee’s legal obligation runs to the beneficiaries, not to your convenience. If the trust document does not authorize a particular distribution, the trustee cannot make it, no matter how reasonable the request sounds.
This does not rule out funding an irrevocable trust with liquid assets. It rules out funding one with the liquid assets that are your financial safety net. Before transferring any cash or marketable security, be honest about whether you could go years without touching it. If the answer is uncertain, keep it out.
Timing matters if long-term care may be in the picture. Federal law imposes a 60-month look-back period for asset transfers. If you move assets into an irrevocable trust and apply for Medicaid within five years, those transfers can trigger a penalty period of ineligibility.4Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Giving up assets you might need for care, and then being penalized for the giving, is a lose-lose.
Your Primary Residence
Transferring your home into a standard irrevocable trust creates several problems that only become expensive after the fact. You lose the ability to sell, refinance, or open a home equity line of credit on your own. Those decisions belong to the trustee, who must follow the trust terms and act for the beneficiaries, not for you.
The Capital Gains Exclusion May Vanish
When you sell a home you have owned and lived in for at least two of the last five years, you can exclude up to $250,000 in capital gains from income tax, or $500,000 for married couples filing jointly. This exclusion survives a transfer into a grantor trust, where you are still treated as the owner for income tax purposes, because the IRS treats the sale as if you made it personally.5eCFR. 26 CFR 1.121-1 – Exclusion of Gain From Sale or Exchange of a Principal Residence If your irrevocable trust is structured as a non-grantor trust, you are no longer the owner for tax purposes, and the exclusion is gone. On a home that has appreciated significantly, that can mean a six-figure tax bill at sale.
When a QPRT Fits
A Qualified Personal Residence Trust is an irrevocable trust designed specifically to hold a home. You keep the right to live in the residence for a set number of years, and the home passes to your beneficiaries at the end of that term at a reduced gift tax value. The restrictions are real: you can only transfer two personal residences, you must outlive the trust term for the tax benefits to work, and once the term ends, you need a fair-market lease from the beneficiaries to keep living there.6Legal Information Institute. Qualified Personal Residence Trust (QPRT) The trust instrument must also follow specific IRS requirements for income distribution and prohibit early payouts to beneficiaries other than you.7eCFR. 26 CFR 25.2702-5 – Personal Residence Trusts A QPRT is a specialized tool with narrow eligibility, not the default answer for putting a house in a trust.
S-Corporation Stock
The IRS strictly limits who can own shares in an S-corporation. Permitted shareholders include U.S. citizens and residents, estates, and certain specific types of trusts.8Internal Revenue Service. S Corporations A generic irrevocable trust is not on that list. If S-corp shares land in an ineligible trust, the company involuntarily loses its S-corp election and becomes a C-corporation, with profits taxed at the corporate level on top of shareholder-level tax when distributions are made.
The trusts that can hold S-corp stock are defined narrowly by statute: grantor trusts where the owner is treated as the taxpayer, Electing Small Business Trusts, and Qualified Subchapter S Trusts, among a few others.9Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined Each has its own qualification rules and election requirements. A careless transfer can blow up the tax status of the entire company, affecting every shareholder.
Property with Outstanding Loans
Most loan agreements include a due-on-sale or due-on-transfer clause that lets the lender demand full repayment if you transfer the property to a new owner. A trust counts as a new owner. For vehicles, boats, and other financed assets, the risk is real: the lender can call the entire balance due. Read the loan agreement and contact the lender before transferring any financed asset.
The Federal Exception for Residential Mortgages
For homes with fewer than five units, federal law gives you a specific protection. A lender cannot enforce a due-on-sale clause when you transfer your home into a living trust, as long as you remain a beneficiary and the transfer does not hand occupancy rights to someone else.10Office of the Law Revision Counsel. 12 U.S. Code 1701j-3 – Preemption of Due-on-Sale Prohibitions The protection applies to both revocable and irrevocable trusts. The implementing regulation adds that the lender can require reasonable notice of any later change in who benefits from or occupies the property. Missing that notice could reopen the lender’s right to call the loan.
Commercial property, vehicles, and other financed assets do not get the same federal shield. Transfers of those into a trust remain subject to whatever the loan agreement says.
Highly Appreciated Assets Your Heirs Would Inherit
When you die owning an appreciated asset, stock bought at $50 that is now worth $200, or a rental property that doubled in value, your heirs generally receive a tax basis equal to the asset’s fair market value at your death. This stepped-up basis wipes out the unrealized capital gain, so your heirs can sell immediately without owing capital gains tax.11Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent
The stepped-up basis only applies to property included in your taxable estate or passing from you by bequest, devise, or inheritance. Assets transferred to an irrevocable trust years ago may not qualify. In Revenue Ruling 2023-2, the IRS confirmed that property held in an irrevocable non-grantor trust, where the grantor had no power to revoke or amend the trust, does not receive a basis adjustment at the grantor’s death. The assets keep their original cost basis, and the beneficiaries inherit the embedded capital gain.
For estates that would fall below the federal exemption anyway, meaning no estate tax was owed regardless, putting appreciated assets in an irrevocable trust sacrifices the stepped-up basis for no offsetting benefit. The math only works when the estate tax savings exceed the capital gains cost, and that depends on how much the asset has appreciated, the size of the estate, and how long the beneficiaries plan to hold.
Assets Tied Up in Litigation or Collateral
Transferring assets to a trust while a lawsuit is pending or reasonably anticipated can be treated as a fraudulent transfer. A court can reverse it and impose additional penalties. Timing matters, and after the fact is too late.
If you expect to need a loan secured by a particular asset, keep it out of the trust. The trustee may not have authority to pledge trust assets for your personal debts, and you cannot pledge what you do not own.
The Gift Tax Side of Every Transfer
Funding an irrevocable trust is a gift for federal tax purposes. When you transfer assets and give up the right to take them back, the IRS treats that as a completed gift to the beneficiaries. If the total value exceeds the annual gift tax exclusion, $19,000 per recipient in 2026, you must file IRS Form 709 to report it.12Internal Revenue Service. Frequently Asked Questions on Gift Taxes
Filing the form does not necessarily mean you owe gift tax. The excess reduces your lifetime estate and gift tax exemption. But that exemption is changing. In 2026, the doubled exemption created by the Tax Cuts and Jobs Act sunsets, reverting to the pre-2018 base of $5 million adjusted for inflation.13Internal Revenue Service. Estate and Gift Tax FAQs The adjusted figure will land around $7 million per person, roughly half of the 2025 exemption. Anyone transferring significant assets into an irrevocable trust in 2026 or later needs to plan around the lower threshold.
There is a subtlety with the annual exclusion itself. The $19,000 applies only to present-interest gifts, where the beneficiary can use the gift immediately. Most irrevocable trusts give beneficiaries a future interest. Future-interest gifts do not qualify for the annual exclusion, so even a $10,000 transfer can require a Form 709 filing.14Internal Revenue Service. Instructions for Form 709 Many trusts use Crummey withdrawal provisions to convert future interests into present interests, but those have to be drafted and administered correctly.
