Estate Tax Explained: Thresholds, Rates, and Planning Strategies

Only 0.2% of Estates Actually Pay This Tax

The estate tax provokes fierce political debate — yet fewer than 1 in 500 American deaths result in any federal estate tax liability. For 2024, estates below $13.61 million ($27.22 million for married couples) owe nothing to the federal government. That threshold was $675,000 just two decades ago. Understanding exactly how this tax works — and why it remains relevant — matters for anyone building substantial wealth or advising those who are.

Federal Estate Tax Versus Inheritance Tax

These are different taxes that people frequently confuse:

• Estate tax: Levied on the deceased person's estate before distribution to heirs. The estate pays the tax, not the beneficiaries. Federal estate tax and some state estate taxes apply.
• Inheritance tax: Levied on the heirs receiving assets. Only six states impose inheritance taxes: Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Maryland is the only state with both.

The federal government has no inheritance tax. Beneficiaries who receive an inheritance generally owe no federal income tax on the assets themselves (though they owe income tax on subsequent income those assets generate).

Federal Estate Tax Structure

However, these rates only apply to amounts exceeding the applicable exclusion amount. For 2024, that exclusion is $13.61 million per individual. An estate worth $15 million pays federal estate tax on approximately $1.39 million — not the full $15 million.

The Sunset Provision: A Major Planning Deadline

The Tax Cuts and Jobs Act of 2017 roughly doubled the estate tax exemption through December 31, 2025. Unless Congress acts, the exemption reverts to approximately $7 million (inflation-adjusted) starting January 1, 2026. This sunset creates a significant planning window. Wealth transferred by gift before the reversion locks in the higher exemption amount permanently — gifts made under the higher exemption are not clawed back if the exemption later decreases.

Unlimited Marital Deduction

Spouses can transfer unlimited assets to each other free of estate and gift tax, provided the surviving spouse is a US citizen. This defers the estate tax problem — it doesn't eliminate it. When the surviving spouse dies, the combined estate faces estate taxes. The solution is portability: the surviving spouse can elect to add the deceased spouse's unused exemption to their own, effectively doubling the couple's combined exemption.

Key Estate Tax Reduction Strategies

• Annual exclusion gifting: In 2024, each person can give $18,000 per recipient per year ($36,000 from a married couple) with no gift tax and no use of lifetime exemption. Systematic gifting removes assets from the estate over time.
• Irrevocable Life Insurance Trust (ILIT): Life insurance proceeds owned by an ILIT avoid estate inclusion, providing liquidity to pay estate taxes without increasing the taxable estate.
• Grantor Retained Annuity Trust (GRAT): Transfer appreciating assets to a trust while retaining annuity payments. If the assets outperform the IRS hurdle rate, excess growth passes to heirs estate-tax-free.
• Charitable contributions and CLATs: Direct bequests to charity are fully deductible from the taxable estate. Charitable lead annuity trusts provide income to charity first, then pass remaining assets to heirs.
• 529 superfunding: Front-load up to five years of annual exclusion gifts ($90,000 per beneficiary in 2024) into 529 education accounts at once.

State Estate Taxes: The Hidden Exposure

Residents of high-estate-tax states face liability well below the federal threshold. Some wealthy individuals change their domicile to states without estate taxes — including Florida, Texas, and Nevada — as part of comprehensive estate planning.

The Stepped-Up Basis Advantage

Inherited assets receive a stepped-up cost basis to fair market value at the date of death. If a parent bought stock for $10,000 that is worth $200,000 at death, heirs inherit with a $200,000 basis — owing no capital gains tax on the $190,000 appreciation. This provision effectively eliminates capital gains on inherited appreciated assets and is one of the most significant tax benefits in the US tax code for wealth transfer.
