What a trust does and does not do for estate taxes

A trust is a legal structure where you transfer ownership of assets to a trustee, who holds them for the benefit of your heirs. Some trusts reduce the estate tax you owe; others do not. The difference depends on which type of trust you use and how you fund it.

A revocable living trust — the most common kind — does not reduce estate taxes at all. You keep control of the assets during your lifetime, and they remain part of your taxable estate when you die. The main benefit is avoiding probate, not lowering taxes.

An irrevocable trust can reduce estate taxes because assets you place in it are no longer considered part of your estate. Once you transfer assets into an irrevocable trust, you cannot take them back or change the terms. That permanent loss of control is what makes the tax reduction possible.

Key Takeaways

  • Revocable trusts do not reduce estate taxes; irrevocable trusts can, because assets in them are removed from your taxable estate.
  • The federal estate tax only applies if your estate exceeds a threshold that changes yearly — currently over $13 million for individuals in 2024, though this amount is set to drop in 2026.
  • Common tax-reducing trusts include irrevocable life insurance trusts (ILITs), charitable remainder trusts, and may have access to personal residence trusts (QPRTs).
  • Transferring assets into an irrevocable trust is permanent and cannot be undone, so this strategy requires careful planning with an attorney.
  • State estate taxes have lower thresholds than federal tax and may apply even if your estate avoids federal tax.

Irrevocable life insurance trusts (ILITs) and why they matter

An irrevocable life insurance trust holds a life insurance policy in the trust's name rather than your own. When you die, the insurance payout goes to the trust, not to your estate. This keeps the death benefit out of your taxable estate, which can save tens of thousands in taxes if your estate is large.

To set up an ILIT, you create the trust first, then apply for a new life insurance policy in the trust's name. You cannot transfer an existing policy into the trust and get the same tax benefit — there is a three-year waiting period, and the policy is still counted in your estate if you die within that window. The trustee (often a family member or professional) pays the premiums, usually with money you give them each year.

An ILIT works best if you have a large estate and expect the life insurance payout to push you over the estate tax threshold. If your estate is small enough to avoid federal estate tax anyway, an ILIT adds complexity without tax benefit.

Charitable remainder trusts for donors who want income

A charitable remainder trust lets you donate assets to charity while keeping income from those assets during your lifetime. When you die or after a set number of years, the remaining assets go to the charity. You get a tax deduction for the present value of what the charity will eventually receive, which can offset estate taxes.

The trade-off is that you must give up the assets eventually — you cannot change your mind and take them back. The charity's share must be at least 10 percent of the initial value. You receive either a fixed payment each year (a charitable remainder annuity trust) or a percentage of the trust's value each year (a charitable remainder unitrust), which varies if the assets gain or lose value.

This strategy makes sense if you own appreciated assets like real estate or stock, want ongoing income, and plan to leave money to charity anyway. The income stream and tax deduction can offset the cost of giving up the assets.

may have access to personal residence trusts (QPRTs) for homeowners

A may have access to personal residence trust lets you transfer your home into a trust while keeping the right to live in it for a set number of years. After that period ends, the home passes to your heirs. The gift tax value of the home is reduced because you retain the right to use it, which lowers the amount counted against your lifetime gift tax limit.

The catch is that if you die before the trust term ends, the entire home value is pulled back into your taxable estate, and you get no tax benefit. The strategy only works if you outlive the trust term — typically 5 to 15 years. You must also pay fair market rent to the trust if you continue living in the home after the term ends, or the IRS will treat it as a gift.

A QPRT is useful if you own a valuable home, expect to live elsewhere eventually, and want to transfer it to heirs at a reduced gift tax cost. It is not useful if you plan to live in the home for the rest of your life or if you are in poor health.

Grantor retained annuity trusts (GRATs) for appreciating assets

A grantor retained annuity trust lets you transfer appreciating assets (like stock or real estate) into a trust and receive fixed payments back for a set term. When the term ends, any remaining assets pass to your heirs tax-free. If the assets grow faster than the IRS interest rate used to value the trust, your heirs receive the growth without gift or estate tax.

GRATs work best for assets you expect to increase in value significantly — a startup stock, commercial real estate, or a growing business. If the assets do not appreciate as expected, the strategy provides no tax benefit. The term is usually short (2 to 10 years) to reduce the risk that you die before it ends.

GRATs are complex and require an attorney to set up correctly. They are most useful for high-net-worth individuals with assets likely to appreciate and the ability to fund the trust without needing the money back.

How the federal estate tax threshold affects your decision

The federal estate tax only applies if your estate exceeds a threshold. In 2024, that threshold is over $13 million for individuals and over $26 million for married couples. Estates below that amount owe no federal estate tax, regardless of whether they use trusts.

The threshold is set to drop significantly in 2026 — to roughly $7 million for individuals and $14 million for couples, unless Congress changes the law. If your estate is close to the current threshold or will be above it in 2026, trust planning becomes more urgent.

State estate taxes have lower thresholds. Some states tax estates over $1 million or even less. If you live in a state with an estate tax, you may need trust planning even if your federal estate is small. Check your state's rules, as they vary widely.

What happens when you fund a trust and what it costs

Funding a trust means transferring ownership of assets into it. For real estate, this requires a new deed. For bank accounts and investments, you change the title or beneficiary designation. For life insurance, you apply for a new policy in the trust's name or, in limited cases, transfer an existing one.

Setting up an irrevocable trust typically costs $1,500 to $5,000 in attorney fees, depending on complexity and your location. Funding it may add costs if you need to refinance a mortgage (some lenders charge fees when a property is transferred into a trust) or hire a tax professional to file gift tax forms.

Once the trust is in place, there are ongoing costs: the trustee may charge fees to manage it, and you may need to file annual trust tax returns if the trust generates income. These costs should be weighed against the tax savings you expect.

Frequently Asked Questions

Can I change my mind after putting assets in an irrevocable trust?

No. An irrevocable trust cannot be changed or undone without the consent of all beneficiaries and, in some cases, a court order. This is why it is critical to work with an attorney and think carefully before funding one. The permanence is what gives it tax power, but it also means you lose control.

Do I still owe income tax on assets in an irrevocable trust?

Yes. Removing assets from your estate for estate tax purposes does not eliminate income tax. You or the trust will owe income tax on interest, dividends, and capital gains the assets generate. Some trusts are taxed as separate entities; others pass income through to beneficiaries. An accountant can explain the specific tax treatment of your trust.

What if my estate is below the federal threshold — do I still need a trust?

Not for federal estate tax purposes. However, you may still want a revocable living trust to avoid probate, or an irrevocable trust if your state has an estate tax or if you want to protect assets from creditors. The decision depends on your goals beyond taxes.

Can a trust protect my assets from creditors or lawsuits?

An irrevocable trust can offer some creditor protection because you no longer own the assets. A revocable trust does not, because you retain control and creditors can still reach the assets. The level of protection varies by state and the type of trust. Consult an attorney in your state for specifics.

What is the difference between a trust and a will?

A will takes effect only after you die and must go through probate. A trust takes effect when you fund it and can avoid probate entirely. A will is simpler and cheaper to set up; a trust is more complex but offers more control over how assets are distributed and can reduce taxes. Many people use both.
