Key Exemptions & Rules

Federal Exemption ($15M for 2026 deaths)

Each individual can pass up to $15 million free of federal estate tax. The amount is set by year of death โ€” it was $13.61M in 2024 and $13.99M in 2025. This exemption is unified with the gift tax exemption -- lifetime gifts reduce your available estate tax exemption.

Portability for Married Couples ($30M)

A surviving spouse can use the deceased spouse's unused exemption (DSUE), effectively doubling the exemption to $30 million. The executor must file Form 706 to elect portability.

Unlimited Marital Deduction

Assets passed to a surviving U.S. citizen spouse are fully deductible. A QDOT (Qualified Domestic Trust) is required for non-citizen spouses.

Annual Gift Tax Exclusion ($19,000 in 2026)

You can gift up to $19,000 per recipient per year (IRS figure for 2025 and 2026; it was $18,000 in 2024) without using any lifetime exemption. Married couples can gift $38,000 per recipient through gift splitting.

What happened to the 2026 sunset

The Tax Cuts and Jobs Act exemption was scheduled to revert to roughly half of its level after 2025. That reversion did not take effect: the IRS basic exclusion amount is $15 million for deaths in 2026, up from $13.99 million in 2025. The amount is set by the year of death, so use the figure for the year that applies.

Federal estate tax by estate size and filing status

Most estates owe nothing at all, and this table shows where that stops being true. It was produced by running the calculator on this page with no deductions entered, so it is the upper bound for each estate size. Find your row, then compare the columns: filing status moves the threshold, and a handful of states levy their own estate tax on top of the federal one. Deductions, marital transfers, and prior gifts all reduce this โ€” enter them above for a figure that fits your situation.

Where you should not rely on this

Do not use these figures to file a return, calculate what you owe, or respond to a tax notice. Federal rules change every year and state rules differ, and this page does not track either. Confirm current figures with the IRS or a licensed tax professional before you act on them.

Frequently asked questions

How much can pass free of federal estate tax?

The exemption is set by year of death. For 2026 deaths it is $15 million per person, up from $13.99 million in 2025 and $13.61 million in 2024. This calculator uses the 2026 figure.

Does a married couple get double?

Effectively yes, through portability. A surviving spouse can claim the deceased spouse's unused exclusion, which brings the combined shelter to $30 million. It is not automatic โ€” the executor must elect portability on Form 706.

Do lifetime gifts reduce the exemption?

Yes. The estate and gift exemptions are unified, so taxable lifetime gifts consume part of the amount available at death. The calculator subtracts the gifts you enter before applying the exemption.

Are the state figures reliable?

Treat them as estimates: each state is modelled as one exemption plus a single top rate, not its full bracket table. State thresholds change on their own schedules. Exemptions were checked against the state revenue departments on 2026-09-28 โ€” Connecticut ($15M, tied to the federal amount), Maine ($7,160,000), New York ($7,350,000) and Washington ($3,000,000 for deaths on or after July 1, 2026) are the published 2026 figures. The District of Columbia figure ($4,873,200) is its published 2025 amount because DC has not published a 2026 one, and the Rhode Island figure could not be re-checked. Confirm with the state revenue department before relying on any of them.
