The federal estate tax exemption determines how much wealth you can pass on tax-free at death. Here is the complete 2026 guide — including what may happen to the exemption in 2026 and beyond.

2026 Federal Estate Tax Exemption

Detail 2026 Amount
Individual exemption $13.99 million
Married couple (with portability) $27.98 million
Estate tax rate (above exemption) 18%–40%
Annual gift tax exclusion $19,000/recipient

Estate Tax Exemption History

Year Individual Exemption
2017 $5.49 million
2018 (TCJA doubled it) $11.18 million
2021 $11.7 million
2023 $12.92 million
2024 $13.61 million
2025 $13.99 million
2026 $13.99 million (TCJA sunset pending)

Important: The TCJA provisions were set to expire December 31, 2025, which would have cut the exemption roughly in half. The final 2026 figure reflects Congressional action or IRS adjustment — monitor IRS.gov for the authoritative 2026 dollar amount.


Who Actually Pays Estate Tax?

The IRS estimates fewer than 0.2% of estates actually owe federal estate tax. With a $13.99 million exemption:

  • A family home worth $500,000 + $2 million retirement accounts + $1 million investments = $3.5 million estate — completely exempt
  • Only estates worth more than $13.99 million face federal estate tax

How the Estate Tax Is Calculated

$$\text{Estate Tax} = (\text{Taxable Estate} - \text{Exemption}) \times \text{Tax Rate}$$

Example: $20 million estate, individual filer

  • Taxable: $20M − $13.99M = $6.01M above exemption
  • Tax at 40% (simplified): ~$2.4M federal estate tax owed
  • Net to heirs: ~$17.6M

In practice, the tax is calculated on a graduated rate schedule from 18% to 40%.


Federal Estate Tax Rates

Taxable Amount Above Exemption Tax Rate
$0–$10,000 18%
$10,001–$20,000 20%
$20,001–$40,000 22%
$40,001–$60,000 24%
$60,001–$80,000 26%
$80,001–$100,000 28%
$100,001–$150,000 30%
$150,001–$250,000 32%
$250,001–$500,000 34%
$500,001–$750,000 37%
$750,001–$1,000,000 39%
Over $1,000,000 above exemption 40%

Portability: Doubling the Exemption for Couples

When one spouse dies, their unused estate tax exemption can be “ported” to the surviving spouse:

  • Executor must file IRS Form 706 within 9 months of the first death (or 6-month extension)
  • The surviving spouse gets both exemptions: up to $27.98 million in 2026
  • No automatic portability — must elect it on Form 706

State Estate Taxes

Several states have their own estate taxes with much lower exemptions:

State Exemption (approx. 2026) Rate
Massachusetts $2 million 0.8%–16%
Oregon $1 million 10%–16%
Washington $2.193 million 10%–20%
Hawaii $5.49 million 10%–20%
Illinois $4 million 0.8%–16%
New York $7.16 million 3.06%–16%
Maryland $5 million 0.8%–16%

Maryland is the only state with both an estate tax and an inheritance tax.


Estate Tax Planning Strategies

Strategy How It Helps
Annual gifts ($19K/person/year) Reduces estate size over time
Irrevocable life insurance trust (ILIT) Keeps life insurance out of taxable estate
Charitable giving / CRT Reduces estate and provides income
Grantor retained annuity trust (GRAT) Transfers appreciation out of estate
Spousal lifetime access trust (SLAT) Uses exemption now before potential sunset
