What Is the Federal Estate Tax Exemption and How Does It Affect Your Estate Plan?

Most Americans will never owe federal estate tax. But the rules are changing fast. Understanding the federal estate tax exemption now could save your family thousands of dollars later.

The federal estate tax is a tax imposed on the transfer of a deceased person's assets to their heirs. The government does not tax every dollar you leave behind. Instead, it only taxes the portion of your estate that exceeds a specific threshold called the exemption amount.

The exemption amount has changed significantly over the decades, and another major shift is coming as soon as 2026. Knowing where the exemption stands today, and where it is headed, is essential for anyone doing estate planning. Here are five key things every American should understand about the federal estate tax exemption.

1. What the Federal Estate Tax Exemption Actually Means

The federal estate tax exemption sets the dollar threshold below which no federal estate tax is owed. If your total taxable estate falls under this threshold at the time of your death, the IRS collects nothing. Your heirs receive their inheritance free from federal estate tax. Only estates that exceed the exemption amount are subject to tax, and only the amount above the threshold gets taxed. The federal estate tax rate can reach up to 40 percent on amounts above the exemption, which makes understanding this number critically important.

2. The Current Federal Estate Tax Exemption Amount in 2025

The Tax Cuts and Jobs Act of 2017 roughly doubled the estate tax exemption. For 2025, the federal estate tax exemption is $13.99 million per individual. This means a single person can pass up to $13.99 million in assets to their heirs without triggering any federal estate tax. The IRS adjusts this number annually for inflation. Here is a quick summary of what this means in practice:

• Individual exemption: $13.99 million in 2025
• Married couple combined exemption: up to $27.98 million using portability
• Assets above the exemption: taxed at rates up to 40 percent
• Annual gift tax exclusion: $18,000 per recipient in 2024, indexed for inflation

3. The 2026 Sunset Provision and Why It Changes Everything

The elevated exemption from the 2017 tax law is not permanent. Current law schedules the exemption to sunset at the end of 2025. Beginning January 1, 2026, the exemption is set to drop back to roughly half its current level, approximately $7 million per individual adjusted for inflation. This change could pull millions of American families back into estate tax territory. Congress may act to extend or modify the exemption, but no action has been guaranteed. Families with estates between $7 million and $14 million need to act now while the higher exemption is still available.

4. How Portability Works Between Married Spouses

Portability is a powerful estate planning tool available to married couples. When one spouse dies, their unused estate tax exemption does not disappear. The surviving spouse can claim and add the deceased spouse's unused exemption to their own. This effectively doubles the exemption for a married couple. For example, if one spouse dies in 2025 using only $3 million of their $13.99 million exemption, the surviving spouse can carry over the remaining $10.99 million. However, portability is not automatic. The estate of the first spouse to die must file a federal estate tax return to elect portability, even if no tax is owed.

5. Why a Will Is Essential Regardless of Estate Tax Exposure

The federal estate tax exemption may protect most Americans from a federal tax bill. But it does not determine who receives your assets. It does not name a guardian for your minor children. It does not designate who manages your estate. A valid will handles all of these decisions. Without a will, your state's intestacy laws control everything. Probate courts make decisions your family may disagree with. Loved ones face delays, legal costs, and unnecessary stress. Every adult needs a will, whether their estate is worth $50,000 or $50 million.

The Big Question: Should You Create Your Estate Plan Before 2026?

The answer is yes, and the sooner the better. The 2026 sunset provision is a real deadline. Even if your estate falls well below the current exemption, your family still needs a will in place. An attorney-drafted estate plan can cost thousands of dollars. But a legally valid, state-specific will does not have to.
