Who Actually Pays the Estate Tax? The Eight-Figure Line Almost No One Crosses

On November 5, 2026, the IRS published its tax year 2027 inflation adjustments. The federal estate tax line rose with them: estates of people who die during 2027 get a basic exclusion of $15,480,000, up from $15,000,000 for deaths in 2026. The line moved again, so it helps to see who actually crosses it, and IRS filing data shows that the dollars come mostly from estates far above eight figures.

Most Estates That File Owe Nothing

Estate tax returns filed in 2024 totaled 7,195. Only 2,663 of them reported any net estate tax, about 37% of filers. Together those estates owed $23,313,220,000. Estates with gross assets of $50 million or more filed 469 of the paying returns and owed $15,845,602,000, roughly 68% of the total. Smaller estates still showed up: 217 taxable returns under $10 million owed $241,980,000. One year earlier, returns filed in 2023 included 3,690 paying estates that owed $44,412,892,000.

Those filings mostly cover deaths under the rules for 2018 through 2025. That system used a $10,000,000 base amount indexed for inflation. For comparison, the Federal Reserve counts 136,779 households in the top 0.1% as of 2026 Q2, with a net-worth floor of $45,796,944 (a cutoff identified for 2022 Q3).

How Section 2010 Draws the Line

Section 2001(a) imposes the tax on the taxable estate of every U.S. citizen or resident (26 U.S.C. § 2001(a)). Section 2010(a) then gives every estate a credit against it (26 U.S.C. § 2010(a)). The credit equals the tax on the basic exclusion amount, which the statute sets at $15,000,000 under § 2010(c)(3)(A). The One Big Beautiful Bill wrote that figure into law, effective for estates of decedents dying and gifts made after December 31, 2025. For deaths in a calendar year after 2026, § 2010(c)(3)(B) indexes the amount for inflation and rounds it to the nearest $10,000. That is why the line moves every year. Above the credit, the top rate under § 2001(c) is 40% on amounts over $1,000,000.

Lifetime Gifts Use Up the Same Exclusion

The estate and gift taxes work as one system. Under § 2001(b)(1), the estate tax is figured on the taxable estate plus adjusted taxable gifts made during life (26 U.S.C. § 2001(b)(1)(B)). The gift tax credit draws on the same applicable credit amount (26 U.S.C. § 2505(a)(1)). Gifts within the annual exclusion stay out of that total. The annual exclusion is $19,000 per recipient for 2026 and $20,000 for 2027. Taxable gifts also lower the gross-estate threshold that triggers a filing requirement (26 U.S.C. § 6018(a)(3)(A)).

Worked Example: A Founder Who Gave Early

A hypothetical single founder dies in 2026 with a taxable estate of $20,000,000, and earlier in 2026, she made $3,000,000 in taxable gifts that her credit covered, so she paid no gift tax.

• Tax base: $23,000,000
• Tentative tax under § 2001(c): $9,145,800
• Less the credit on the 2026 exclusion: $5,945,800
• Estate tax before other credits: $3,200,000

The gifts stayed in the tax base and used up $3,000,000 of exclusion that the estate would otherwise have had.

Married Couples Can Double It, but Only by Election

A surviving spouse’s applicable exclusion equals their own basic exclusion plus the deceased spousal unused exclusion amount, or DSUE (26 U.S.C. § 2010(c)(2)(B)). DSUE is the lesser of the basic exclusion or whatever the last deceased spouse left unused (26 U.S.C. § 2010(c)(4)). Suppose the first spouse dies in 2026 having used none of it. The survivor could then shelter up to $30,000,000. Portability requires an election, though. The executor must make it on a timely filed Form 706 (26 CFR 20.2010-2).

Traps That Catch Large Estates

• Skipping the Form 706: When the first estate owes no tax, families often file nothing, and the DSUE is lost.
• Remarriage: DSUE comes from the last deceased spouse, so a later marriage can replace a large DSUE with a small one.
• Hard-to-sell assets: Among estates that paid tax, 818 returns reported closely held stock worth $13,984,755,000. Business interests can be difficult to turn into cash by the payment deadline.
• Gifts still in the estate: Gifts that remain included in the gross estate are left out of adjusted taxable gifts and taxed as estate assets instead (26 U.S.C. § 2001(b)).

Deciding Whether Exclusion Planning Fits

Start with three questions. Could the estate, plus prior taxable gifts, realistically pass the indexed line by the time of death, and is the wealth tied up in growing or illiquid assets, such as private companies or partnerships? Could the household give up control of assets and the income they produce? Lifetime gifting is not for everyone. It is a poor fit for owners who need that income, for estates well below the line, and for couples who can cover their exposure with a portability election alone.

What to Watch Next

Revenue Procedure 2026-35 sets the 2027 figures. The IRS will publish a new indexed amount each year after that. When the 2025 filing-year data comes out, it will show whether the higher exclusion has made the group of paying estates even smaller and more top-heavy.
