The federal estate tax applies to the transfer of wealth at death — and with a top rate of 40%, it can represent a substantial erosion of family wealth for taxable estates. In 2026, estate planning is particularly critical because the elevated exemption amounts established by the Tax Cuts and Jobs Act of 2017 are scheduled to sunset after December 31, 2025 (unless Congress acts), which could reduce the per-person exemption to approximately $7 million. This guide covers the current federal estate tax framework and the most effective planning strategies available in 2026.

The 2026 Federal Estate Tax Exemption: TCJA Sunset Watch

The Tax Cuts and Jobs Act of 2017 nearly doubled the federal estate tax exemption, from approximately $5.49 million to $11.18 million per person ($22.36 million for married couples), indexed for inflation. In 2026 (assuming no legislative change), the exemption stands at approximately $13.99 million per person. However, unless Congress acts, the TCJA provisions are scheduled to sunset after 2025, reverting the exemption to approximately $7 million per person (inflation-adjusted). As of April 2026, monitor Congressional activity carefully — any legislative changes could significantly affect estate planning strategy.

"The TCJA sunset — or the legislation that Congress passes in response to it — is the most significant estate planning event for high-net-worth families in a generation. Families with estates above $7 million who have not already accelerated gifting and trust planning are at risk of a substantially larger estate tax bill if exemptions are reduced. The time to act is now, not after legislation passes." — Catherine Merriweather, JD, LLM Tax

Key Estate Tax Planning Strategies

1. Annual Gift Tax Exclusion

The annual gift tax exclusion allows each person to give up to $18,000 (2025; confirm 2026 amount) to any number of recipients per year without using any lifetime exemption or filing a gift tax return. A married couple can give $36,000 per recipient per year through gift-splitting. This seemingly modest exclusion can remove substantial wealth from a taxable estate over time — a couple with 4 children and 8 grandchildren can transfer $432,000 per year ($36,000 × 12 recipients) free of gift tax.

2. Irrevocable Life Insurance Trust (ILIT)

Life insurance proceeds are included in a decedent's estate if they owned the policy at death. An Irrevocable Life Insurance Trust (ILIT) owns the policy instead — keeping the death benefit outside the taxable estate while providing liquidity to pay estate taxes, fund specific bequests, or support heirs. ILITs must be properly structured: the grantor cannot be a trustee, and Crummey withdrawal rights must be included for annual exclusion gifts to fund premiums.

3. Spousal Lifetime Access Trust (SLAT)

A SLAT allows one spouse to use their lifetime exemption to fund an irrevocable trust for the benefit of the other spouse and descendants. The beneficiary spouse can access the trust assets during their lifetime, while the assets are outside both spouses' taxable estates. SLATs became extremely popular planning tools as advisors raced to use TCJA exemptions before potential sunset. Be aware of reciprocal trust doctrine issues if both spouses establish SLATs.

4. Grantor Retained Annuity Trust (GRAT)

A GRAT allows you to transfer appreciating assets to an irrevocable trust while retaining an annuity payment for a fixed term. At the end of the term, any remaining trust assets pass to beneficiaries free of gift tax. The taxable gift is minimal (or zero in a "zeroed-out" GRAT structure) because the retained annuity is valued at the IRS's assumed rate of return (the Section 7520 rate). GRATs work best when assets are expected to grow faster than the Section 7520 rate.

5. Charitable Giving Strategies

Charitable bequests and lifetime charitable gifts reduce the taxable estate. More sophisticated strategies include Charitable Remainder Trusts (CRTs — retain income stream, remainder to charity, estate tax deduction), Charitable Lead Trusts (CLTs — charity receives income, remainder to family), and Donor Advised Funds (DAFs — immediate deduction, strategic multi-year grant-making). For large estates with philanthropic intent, these tools can dramatically reduce estate taxes while advancing charitable goals.
