Most estates don't owe federal estate or gift tax, because you can give away or leave substantial amounts of property tax-free. The federal estate and gift taxes are really one tax, called the "unified gift and estate tax." The unified gift and estate tax totals the value of property you give away during life and leave at your death. For deaths in 2025, you can leave or give away up to $13.99 million ($27.98 million for married couples) before your estate needs to pay federal taxes. Taxes aren't assessed until death, unless you give away $13.99 million in taxable gifts (very unusual) during your lifetime.
The "Big Beautiful Bill" passed by Congress and signed by the president in July 2025 increases the federal estate tax exemption from $13.99 million to $15 million ($30 million for married couples) beginning in January 2026. This $15 million tax exemption is labeled "permanent," meaning it isn't scheduled to be changed (other than annual increases for inflation) or eliminated in the future. (However, a future Congress and president could pass a new law that increases, decreases, or eliminates this exemption.)
The personal exemption allows a set dollar amount of property to pass tax-free, no matter who inherits it. As noted above, the individual exemption for deaths in 2025 is $13.99 million and will increase to $15 million in 2026. After 2026, the exemption amount will rise yearly with inflation.
If your estate is worth less than the gift and estate tax exemption—as are the estates of more than 99.9% of the population—it won't owe federal estate tax when you die. If you have made taxable gifts during your life, the amount of your personal exemption will be reduced by the amount of those taxable gifts. (Some gifts aren't taxable, and you might be able to reduce your total estate tax with nontaxable gifts.)
All property left to a surviving spouse passes free of estate tax; this is called the marital deduction. The marital deduction isn't allowed for property left to noncitizen spouses, but the personal estate tax exemption can be used for property left to noncitizen spouses. (I.R.C. § 2056 (2025).)
All property left to a tax-exempt charity is also free of estate tax. (I.R.C. § 2056(a) (2025).)
A surviving spouse gets a big tax break. If the deceased spouse didn't use up the individual tax exemption, the survivor can use what's left. That gives the couple a total exemption of twice the individual exemption amount, which can be split between them in any way that provides the greatest tax benefit. For example, say a man dies and leaves $10 million to his widow; no estate tax is owed because property left to a spouse is tax-free. The widow then dies, leaving $20 million (her own $10 million plus the $10 million she inherited from her husband) to their children. Her estate won't owe any estate tax, even though her estate is over the exemption amount, because her estate can use some of the husband's unused exemption.
Even if your estate isn't big enough to owe federal estate tax, the state might still take a bite. Several states collect either their own estate or inheritance taxes. (See Estate and Gift Tax FAQ.) If you live in one of those states, there's not much you can do to avoid paying those taxes, save moving to another state.

If you think your estate will be large enough to trigger federal estate tax, get advice from an experienced estate planning lawyer who can help you sort through your options. There are a few estate planning tools you can use to reduce estate tax liability. (For instance, Tax-Saving AB Trusts.)
