What actually reduces estate tax, and what does not

Estate tax only applies if your estate exceeds a threshold set by federal law. For 2024, that threshold is $13.61 million for a single person and $27.22 million for a married couple filing jointly. If your estate is below that number, you owe no federal estate tax regardless of what you do. The threshold changes yearly and is scheduled to drop significantly after 2025, so the strategies that matter depend on whether your estate is currently over the line or will be after the threshold falls.

If you are below the threshold now, the main question is whether you will stay below it. If you will, no strategy is necessary. If you might exceed it — because your assets are growing, because you expect an inheritance, or because the threshold will drop — then the methods below become relevant. If you are already over the threshold, these methods can reduce what your heirs owe.

One critical point: strategies that reduce estate tax often involve giving away money or assets during your lifetime, or structuring ownership in ways that affect how much control you keep. The tax savings must be weighed against what you give up. A strategy that saves $100,000 in taxes but costs you $200,000 in lost income or control is not a win.

Key Takeaways

  • Federal estate tax only applies to estates over $13.61 million (single) or $27.22 million (married) in 2024, and most people never pay it.
  • The annual gift tax exclusion lets you give up to $18,000 per person per year without counting against your lifetime limit, and married couples can give $36,000 combined.
  • Lifetime gifts reduce your taxable estate dollar-for-dollar, but you lose control of that money and cannot get it back.
  • Irrevocable trusts, life insurance trusts, and charitable trusts can remove assets from your taxable estate, but they require legal setup and ongoing administration.
  • The federal threshold drops after 2025 unless Congress acts, which may affect whether you need a strategy at all.

Using the annual gift exclusion to move money tax-free

The annual gift tax exclusion is the simplest tool. In 2024, you can give $18,000 to any person without filing a gift tax return or counting it against your lifetime estate tax exemption. If you are married, your spouse can give another $18,000 to the same person in the same year, for a total of $36,000. You can do this every year, to as many people as you want.

This works because the gift is removed from your taxable estate immediately. If you give $18,000 to your child this year, that $18,000 is gone from your estate for tax purposes. If that money grows to $25,000 by the time you die, the growth stays out of your taxable estate too. Over time, this can move a significant amount of wealth to your heirs without tax cost.

The catch is that the money is truly gone. You cannot take it back, and you cannot control how the recipient uses it. If you give $18,000 to an adult child and they spend it, you have no recourse. If you give it to a minor, you typically need to set up a custodial account or trust to manage it until they reach adulthood. The exclusion also does not apply to gifts that come with strings attached — if you give money but retain the right to income from it, or the right to take it back, the IRS treats it as still part of your estate.

Irrevocable life insurance trusts and other trust structures

An irrevocable life insurance trust (ILIT) is a legal structure that owns a life insurance policy on your life. When you die, the policy pays out to the trust, and the trust distributes the money to your heirs. Because the trust owns the policy, not you, the payout does not count as part of your taxable estate — even if the payout is millions of dollars.

To set this up, you create the trust, transfer an existing policy into it (or have the trust purchase a new one), and then make gifts to the trust each year to cover the premiums. Those gifts count against your annual exclusion, but the eventual payout stays out of your estate. This is useful if you have a large estate and life insurance is part of your plan anyway.

The word "irrevocable" matters: once the trust is created and the policy is transferred in, you cannot change your mind, take the policy back, or change who inherits the money. You also cannot be the trustee — someone else must manage it. This loss of control is the trade-off for the tax benefit. An attorney must draft the trust, and the trustee must file annual tax returns for the trust. These costs are real, though usually modest compared to the tax savings for large estates.

Other irrevocable trusts work similarly. A grantor retained annuity trust (GRAT) lets you transfer appreciating assets into a trust, receive payments back for a set term, and then pass the remainder to heirs at a reduced tax cost. A may have access to personal residence trust (QPRT) lets you transfer your home into a trust, live in it for a set period, and then pass it to heirs. Both require legal setup and are most useful for estates well over the current threshold.

Charitable trusts and donor-advised funds

If you plan to give to charity anyway, a charitable remainder trust (CRT) can reduce your taxable estate while providing income during your lifetime. You transfer assets to the trust, receive payments from it for life (or a set term), and the remainder goes to charity. The value of the charitable portion is deducted from your taxable estate, and you get an income tax deduction in the year you create the trust.

A donor-advised fund (DAF) is simpler and requires no legal setup. You make a contribution to the fund, receive an immediate income tax deduction, and then recommend grants to charities over time. The money is out of your taxable estate immediately, but you keep some say in where it goes. DAFs are offered by community foundations, financial institutions, and charitable organizations. Contributions are irrevocable — you cannot take the money back — but you have flexibility in timing the grants.

Both structures work best if charity is already part of your plan. If you are using them primarily for tax savings and do not actually want to give to charity, the IRS may challenge the arrangement. The tax benefit is real, but it should align with your actual charitable intentions.

Spousal lifetime access trusts and portability elections

A spousal lifetime access trust (SLAT) is an irrevocable trust created by one spouse for the benefit of the other spouse and children. The first spouse funds the trust with a large gift (using the annual exclusion, lifetime exemption, or both), and the second spouse can access the money if needed. When the first spouse dies, the trust assets are not part of their taxable estate. When the second spouse dies, the assets pass to the children outside the second spouse's taxable estate.

This is useful for married couples with large estates who want to remove assets from both spouses' estates. The downside is that the first spouse cannot access the money — it is truly irrevocable — and the trust must be carefully drafted to avoid being pulled back into the first spouse's estate for tax purposes.

A simpler option for married couples is the portability election. When the first spouse dies, their unused exemption can be transferred to the surviving spouse, effectively doubling the exemption. This requires filing an estate tax return even if no tax is owed, and the election must be made within nine months of death. Portability does not require any trust or lifetime planning — it is automatic if you file the return — but it only works if the first spouse to die has a smaller estate than the second.

Lifetime gifts and the lifetime exemption

Beyond the annual exclusion, you have a lifetime exemption — a total amount you can give away during your lifetime without owing gift tax. In 2024, that exemption is $13.61 million for a single person. Any gift above the annual exclusion counts against this lifetime total. Once you use it up, gifts above the annual exclusion trigger gift tax.

The lifetime exemption and the estate tax exemption are linked: money you give away during your lifetime counts against the same pool as money in your estate when you die. If you give away $5 million during your lifetime, your estate exemption drops to $8.61 million. This means lifetime gifts do not always save tax — they just move the tax burden from estate tax to gift tax, which are the same rate.

However, lifetime gifts do save tax in one situation: if the asset is growing. If you give away $1 million that grows to $3 million by the time you die, only the $1 million counts against your exemption. The $2 million in growth is never taxed. This is why lifetime gifts work best for appreciating assets — real estate, business interests, stocks — rather than cash.

What does not reduce estate tax

Some common beliefs about estate tax are wrong. Putting assets in joint names with your children does not reduce estate tax — the full value still counts in your estate unless you can prove the other owner contributed to the purchase. Naming beneficiaries on bank accounts or retirement accounts does not reduce estate tax — the full balance counts in your estate. A simple will does not reduce estate tax at all.

Moving to a state with no state income tax does not reduce federal estate tax, though it may reduce state-level estate or inheritance taxes if you live in one of the 12 states that impose them. Spending down your assets does reduce estate tax, but it also means less money for you to live on.

Life insurance does reduce estate tax, but only if structured correctly. If you own the policy, the payout is part of your taxable estate. If the policy is owned by an irrevocable trust (an ILIT), the payout is not. This is why the structure matters more than the insurance itself.

The threshold drop after 2025 and why timing matters

The current high exemption ($13.61 million single, $27.22 million married) is set to expire after December 31, 2025. Unless Congress acts, the exemption will drop to roughly $7 million single and $14 million married in 2026, adjusted for inflation. This means an estate that is safely below the threshold today could be well above it in two years.

If your estate is between $7 million and $13.61 million, you have a narrow window to use lifetime gifts or other strategies before the threshold drops. Waiting until 2026 could mean owing tax on assets you could have moved tax-free in 2024 or 2025. If your estate is below $7 million, you likely do not need to act unless it is growing rapidly.

This uncertainty is why many people consult an estate tax attorney now rather than waiting. An attorney can model your specific situation under both the current rules and the post-2025 rules, and help you decide whether action makes sense. The cost of a consultation is usually far less than the tax cost of guessing wrong.

Frequently Asked Questions

Do I need to do anything if my estate is below the threshold?

No. If your estate is below $13.61 million (single) or $27.22 million (married) in 2024, you owe no federal estate tax no matter how you structure things. You should still have a will or trust to direct who inherits and to avoid probate, but that is separate from estate tax planning.

Can I undo a gift if I change my mind?

No. Once you give money away, it is gone. You cannot take it back for tax purposes, even if you change your mind later. This is why gifts should only be made to people you trust and amounts you can afford to lose.

What happens if I give away more than the annual exclusion?

You must file a gift tax return (Form 709) and the excess counts against your lifetime exemption. You do not owe tax unless you have used up your entire lifetime exemption, but the IRS tracks it. If you give away $50,000 to one person in one year, $32,000 counts against your $13.61 million lifetime exemption.

Is a trust better than just naming beneficiaries?

It depends on your goals. A trust gives you control over how and when heirs receive money, can reduce estate taxes if structured correctly, and avoids probate. Naming beneficiaries is simpler and costs nothing, but offers no tax savings and no control over how the money is used. For large estates, a trust usually makes sense. For small estates, it may not be worth the cost.

Should I wait to see what Congress does about the threshold after 2025?

If your estate is close to the current threshold, waiting is risky. If Congress does nothing, the threshold drops and you may owe tax on assets you could have moved tax-free now. If Congress raises the threshold, you will have acted unnecessarily but will not have lost anything. Most advisors recommend acting now if you are in the uncertain zone, rather than gambling on future legislation.
