How the Estate Tax Works: Who Actually Pays It, and How Little It Raises
The Million Dollar Question: In 2026, what share of American estates will actually owe any federal estate tax?
A) About 10% B) About 2% C) About 0.2% D) Less than 0.1%Read on for the answer.
The federal estate tax is the most politically fought-over line in the tax code and, in dollar terms, close to irrelevant to how the government is funded. Here’s what it actually taxes, who it actually reaches, what it actually raises, and how the planning gap between the 40% headline rate and what wealthy estates actually pay really works.
What it is
The federal estate tax is a single, unified tax on the transfer of wealth — levied partly while someone is alive (as the gift tax) and partly when they die (as the estate tax), drawing on the same lifetime allowance either way. That allowance is formally called the basic exclusion amount, and for 2026 it is $15,000,000 per person, or effectively $30,000,000 for a married couple, up from $13,990,000 in 2025, according to the IRS’s own 2026 inflation-adjustment release. Only the value transferred above that number is taxed, at a top federal rate of 40%, and only on the excess — an estate of $18 million in 2026 owes 40% of $3 million, not of $18 million, before deductions.
That $15 million figure is new and, for the first time in years, not temporary. The exemption had doubled under the 2017 tax law but was scheduled to roughly halve again after 2025. The One Big Beautiful Bill Act (Public Law 119-21, enacted July 2025) canceled that scheduled drop and set the $15 million figure as permanent starting with 2026 deaths and gifts, indexed for inflation every year after. Years of “use it or lose it” planning urgency around the old sunset date are, for now, over.
A parallel allowance — the generation-skipping transfer (GST) tax exemption — is also $15,000,000 in 2026, taxed at the same 40% rate on anything that skips a generation above that amount. Unlike the main exemption, it is not portable between spouses. Both pieces of plumbing matter more to the dynasty trusts covered later in this piece than to an ordinary estate.
Who actually pays it
Very few people. For 2023 decedents, the Internal Revenue Service’s own data — compiled by the nonpartisan Tax Policy Center — shows about 7,100 federal estate tax returns (Form 706) filed, of which only around 4,000 were actually taxable. Against roughly 2.8 million deaths that year, that’s “less than 0.2 percent” of all decedents filing a return, and a noticeably smaller share than that actually owing anything after exemptions and credits are applied — on the order of one death in 700.
That reach has been shrinking for decades, almost entirely because the exemption has grown faster than most estates. In 2001, before the exemption was raised repeatedly through the 2000s and 2010s, about 109,600 estate tax returns were filed and roughly 50,500 of them owed tax — more than ten times today’s taxable count, against a smaller population. The 2026 exemption increase pushes the reach lower still: an estate that would have owed tax in 2025 at $13.99 million can cross entirely tax-free in 2026 if it sits between that figure and $15 million.
Filing matters even when no tax is owed. A surviving spouse inherits the deceased spouse’s unused exemption only through portability — and portability requires the first estate to file Form 706 on time, a step some executors skip precisely because the estate itself owes nothing. Skipping it can cost the second spouse’s estate real exemption years later.
How little it raises
The federal estate tax raised roughly $30 billion in 2025 — under 1% of total federal revenue, according to the Tax Foundation. The Tax Policy Center’s estimate for 2023 liability, $24.0 billion, points in the same direction.
Put next to history, the number is strikingly flat in nominal terms even as the exemption has climbed. In 2001 — with an exemption of roughly $675,000, a small fraction of today’s $15 million — the tax raised $23.7 billion. By 2009, with the exemption already up to $3.5 million, revenue had fallen to $13.6 billion. By 2021 it had recovered to $19.2 billion. Three decades of a rising exemption and a growing national pool of wealth have landed revenue back close to where it started, in nominal dollars, which means it has fallen sharply as a share of a much larger economy. Whatever the estate tax is accomplishing — and defenders and critics disagree sharply on what that is — funding the federal government at any meaningful scale is not it.
It wasn’t always this generous. The exemption was $675,000 in 2001, $1.5 million by 2005, and $5 million (indexed) by 2011 before the 2017 tax law doubled it again — a two-decade run in which the exemption has grown roughly twenty-two-fold while the top rate has drifted down from 55% to 40%. Each step narrowed who the tax actually reaches.
How it works (the mechanics most people skip)
Three features of the mechanics matter for understanding who is actually exposed.
First, the lifetime gift tax and the estate tax share one allowance. A taxable gift made this year reduces, dollar for dollar, what remains available at death. Not every gift counts against it: the annual exclusion lets anyone give $19,000 per recipient per year in 2026, to as many recipients as they like, entirely outside the lifetime pot, and tuition or medical payments made directly to the provider are excluded without limit.
Second, the federal number is only one layer. Twelve states and the District of Columbia levy their own estate or inheritance tax on top of (or instead of) the federal one, frequently with exemptions far below $15 million — Oregon’s sits at $1 million, for instance. A family can clear the federal threshold entirely and still owe a state’s tax; this site covers the state layer in detail separately.
Third, the tax is assessed on the taxable estate, not gross assets — life insurance payable to the estate, debts, funeral costs, and the marital and charitable deductions all adjust the number before the 40% rate ever applies.
How the very wealthy plan around it
The planning gap between a 40% statutory rate and what very large estates actually pay doesn’t come from evading the tax; it comes from moving growth out of the taxable estate before death, using tools years ahead of the return itself.
The best-documented is the GRAT — a grantor retained annuity trust. A person places an asset into the trust, which pays back the original value (plus a modest IRS-set interest rate) over a term of years; whatever the asset earns above that rate passes to the trust’s beneficiaries free of gift and estate tax. A $100 million GRAT that grows to $130 million sends roughly $30 million to heirs tax-free, while the original $100 million is repaid into the estate — a structure tax lawyers describe, per ProPublica’s 2021 investigation of IRS tax records, as “heads I win, tails we tie”: if the assets grow, the gain escapes tax; if they don’t, nothing is lost beyond the legal cost of setting it up. ProPublica’s analysis found that more than half of America’s 100 richest people have used GRATs or similar trusts, and — citing its review of tax records — reported that Laurene Powell Jobs used a series of GRATs after 2011 to move roughly half a billion dollars to her family largely free of gift and estate tax, avoiding an estimated $200 million in tax along the way. That figure is ProPublica’s reporting on tax-record data, not a public filing Powell Jobs herself disclosed, and it is cited here on that basis.
The second tool is the dynasty trust: an irrevocable trust funded once, with GST exemption allocated at funding, that can then hold assets for multiple generations without triggering estate or GST tax at each individual death. States like South Dakota, Nevada, and Wyoming have extended or abolished the old rule against perpetuities specifically to host these trusts, which is why a meaningful share of American trust assets sits in states where almost none of the beneficiaries actually live.
The third is the step-up in basis — a separate rule from the estate tax itself, but the one that makes “hold until death” the dominant strategy for appreciated assets. An asset’s cost basis resets to its market value on the date of death, erasing the capital gains tax on everything it appreciated during the owner’s lifetime. Combined with borrowing against the asset instead of selling it while alive, step-up turns “buy, borrow, die” into a way of realizing the value of an appreciated asset without ever realizing a taxable gain on it.
What it costs to avoid it
None of this is free, and none of it is universally available. A GRAT carries real mortality risk: the grantor has to outlive the trust’s term for the tax benefit to hold, and dying early can unwind the strategy’s advantage. Dynasty trusts and GRATs both require legal drafting, ongoing trustee administration, and — as this site’s trust-cost reporting has already quantified — recurring fees that typically run from a fraction of a percent to around 1–2% of assets annually depending on the trustee and the complexity of the structure. The arithmetic only works at a scale where those costs are a rounding error against the growth being sheltered, which is a meaningfully different threshold than simply being above the $15 million exemption line. Below it, the standard estate-tax exemption and the step-up already shelter most families without any of this machinery.
Scale the cost against what’s being sheltered and the logic becomes clearer. A family funding a GRAT or dynasty trust with $20–$50 million in appreciating assets can expect legal drafting fees in the tens of thousands of dollars and ongoing trustee or administration costs in the same broad 0.5%–2%-of-assets range this site has documented for trusts generally — real money, but small next to tens of millions in sheltered future growth. A family funding the same structure with $500,000 would pay a similar flat drafting cost against a far smaller base, which is exactly why these tools cluster at the top of the wealth distribution rather than appearing throughout it.
What people get wrong
That the 40% rate applies to the whole estate. It applies only to the amount above the $15 million (or $30 million, married) exemption. An estate at or below the exemption owes nothing at all, regardless of size relative to, say, the typical American household.
That the federal number is the whole story. Twelve states and DC layer their own estate or inheritance tax on top, with exemptions as low as $1 million — a family can clear the federal line by a wide margin and still owe a state.
That the exemption was about to collapse. For years, estate planning ran on the assumption that the doubled exemption would sunset after 2025 and roughly halve. The One Big Beautiful Bill Act made the higher figure permanent instead — the sunset that was supposed to happen, didn’t.
That the estate tax and the step-up in basis are the same lever. They are legally distinct and can point in opposite directions. Assets given away during life to dodge the estate tax generally keep their original cost basis; assets held until death get both the estate-tax exemption and the step-up, if the estate is below the threshold — which is exactly why “give early” is not automatically the better move for a family that isn’t anywhere near $15 million.
Bottom line
The Million Dollar Question, answered: D, and closer to one death in 700 than to one in 500. Roughly 0.2% of American decedents’ estates file a federal estate tax return at all, and a smaller share than that — somewhere on the order of 0.1% to 0.15% of all deaths — actually owe anything once exemptions and credits are applied. What the tax touches is already the top of the top, and what it raises for the federal government, at roughly $30 billion a year, is well under 1% of federal revenue — a rounding error next to income and payroll taxes. The real action for very large estates isn’t at the Form 706 stage at all; it happens years earlier, in GRATs, dynasty trusts, and the decision to hold appreciated assets until death rather than sell them — tools built for a threshold most Americans will never cross, operating upstream of a tax that, for almost everyone else, was never going to apply in the first place.
