Passing wealth on is part of how wealth is measured over generations, and in the United States a federal tax can apply to transfers at death and during life. This article explains how the federal estate and gift tax framework works in 2026, using Internal Revenue Service figures. It describes United States federal rules only; individual states, the UK and European countries have their own, very different systems.
What is the federal estate tax, and who pays it?
According to the IRS, the estate tax is a tax on the right to transfer property at death. The estate, not the heirs, files the return and settles any tax due. The return, Form 706, accounts for everything the person owned or had certain interests in at death, valued at fair market value.
For most households the tax is never triggered. The IRS publishes a filing threshold for each year of death, and a return is required only when the gross estate, plus adjusted taxable gifts and the specific gift tax exemption, exceeds that threshold. Below it, there is generally no federal estate tax return to file, apart from the case of a portability election, covered below.
How high is the 2026 threshold?
The IRS lists the filing threshold by year of death. As of its page last reviewed on December 22, 2025, the figures for recent years are:
| Year of death | Filing threshold |
|---|---|
| 2018 | $11,180,000 |
| 2020 | $11,580,000 |
| 2022 | $12,060,000 |
| 2024 | $13,610,000 |
| 2025 | $13,990,000 |
| 2026 | $15,000,000 |
The 2026 amount is the basic exclusion amount set at $15,000,000 for estates of decedents dying in 2026, up from $13,990,000 in 2025, according to the IRS. The jump from 2017 ($5,490,000) to 2018 ($11,180,000) shows how much the threshold depends on legislation, not just inflation. The 2026 amount was set by legislation.
The simple difference between 2025 and 2026 is $15,000,000 minus $13,990,000, which is $1,010,000, or about 7.2% higher.
Does the tax apply to every dollar above the threshold?
Not exactly. The IRS explains that the tax is computed on the estate and then reduced by the available unified credit. The threshold is the practical result of that credit. The IRS page on changes to the rules does not state a current top rate; it points to the rate schedule in the tax code and notes that top rates fell from 55 percent in 2001 to 35 percent in 2010, then rose to 40 percent in 2013.
Lifetime taxable gifts matter here too. According to the IRS, lifetime taxable gifts made from 1977 onward are included in the estate tax computation. The estate tax and the gift tax are therefore linked: they draw on one shared exclusion rather than two separate ones.
How does the annual gift exclusion work?
The IRS says the annual exclusion is $19,000 per recipient for gifts made in 2025 and again in 2026. A married couple giving together can give $38,000 per recipient. The donor, not the recipient, is generally responsible for any gift tax.
The IRS also lists several gifts that are generally not taxable:
- Gifts to your spouse, which are eligible for the marital deduction.
- Tuition or medical expenses you pay for someone.
For a spouse who is not a US citizen, the IRS inflation notice for 2026 sets the annual exclusion at $194,000, up $4,000 from 2025.
A worked example of annual gifts
Illustrative arithmetic: a parent with three children gives each $19,000 in 2026. That is 3 × $19,000 = $57,000 in total. If the parent’s spouse joins in, the combined limit is 3 × $38,000 = $114,000. Gifts at or below those per-person levels are within the annual exclusion.
Now suppose one child receives $50,000 from a single donor. The amount above the annual exclusion is $50,000 minus $19,000, or $31,000. That excess is the part that could count as a taxable gift reported by the donor and, since lifetime taxable gifts feed into the estate tax computation, it uses up part of the shared lifetime exclusion rather than producing a tax bill straight away. Whether a return is required in a specific case depends on the details, which is why the donor-side Form 709 rules deserve a close read.
Why do gifts and the estate share one exemption?
The system is designed to tax the cumulative transfer of wealth, whether made during life or at death. For 2026, the IRS states that the basic exclusion amount for gifts for calendar year 2026 is also $15,000,000. Because lifetime taxable gifts are added back in the estate computation, a person who has made large taxable gifts has less exclusion left at death.
A rough way to picture it, using hypothetical figures:
- Lifetime taxable gifts above annual exclusions: $3,000,000.
- Remaining basic exclusion at death in 2026: $15,000,000 minus $3,000,000 = $12,000,000.
- An estate of $12,000,000 would sit right at that remaining amount.
This simplified picture ignores valuation changes, deductions and credits, so it should be read as an illustration of the logic and not as a calculation method.
What is portability, and who can use it?
Portability applies to married couples. According to the IRS, beginning January 1, 2011, the estate of a decedent survived by a spouse may elect to pass any of the decedent’s unused exclusion to the surviving spouse. The election is made on a timely filed estate tax return for the decedent. The IRS also notes that simplified valuation rules for estates without a filing requirement do not apply if the portability election is made.
Illustrative arithmetic: if the first spouse to die in 2026 uses $4,000,000 of the $15,000,000 exclusion, the unused portion is $11,000,000. A surviving spouse who receives it could add it to their own exclusion, giving $15,000,000 + $11,000,000 = $26,000,000 in this simplified example. The mechanics, including any interaction with the survivor’s own gifts, are set out in the IRS instructions for Form 706.
This is a notable case where an estate may file a return even though no tax is due, simply to preserve the unused amount.
Is the exemption permanent?
The history above says no. The filing threshold was $5,000,000 in 2011 and rose in steps, then roughly doubled from 2017 to 2018, and reached $15,000,000 in 2026 under legislation the IRS describes as increasing the basic exclusion amount for calendar year 2026. Past changes were driven by law, so the threshold has not followed a straight line.
Readers should therefore treat the 2026 figure as the rule for 2026 and check the IRS for the year that matters. This article makes no forecast about future thresholds.
How does wealth transfer fit into the bigger picture?
Net worth, not income, is what gets passed on, a distinction explored in what wealth really means beyond income. Distribution data such as the Federal Reserve wealth shares show how concentrated holdings are, and the federal exemption helps explain why the tax reaches only the top slice of estates. For most households, the more pressing planning questions concern steady habits, such as those in why consistency matters more than big wins, and a reserve like the one discussed in building a financial safety net.
State-level inheritance and estate taxes, retirement account rules and the tax basis of inherited assets are separate topics that this article does not cover.
A high threshold, with details that still matter
The 2026 federal estate tax threshold of $15,000,000, the $19,000 annual gift exclusion and the portability election together define who faces federal transfer tax and how. Most estates fall below the threshold, but the shared lifetime exclusion, the 1977 look-back for taxable gifts and the portability filing show why the rules reach beyond the very largest estates. Anyone with a specific situation should consult the current IRS instructions or a qualified professional.
