How does estate and gift tax planning work in 2026?

TL;DR. The 2026 annual gift exclusion is $19,000 per recipient, and the lifetime estate and gift tax exemption is scheduled to sunset from $13.61 million (2024) back to roughly $7 million per person at the end of 2025 unless Congress extends it. An estate and gift tax calculator helps you model annual exclusion gifts, lifetime exemption usage, and trust-based strategies to transfer wealth efficiently before the unified credit drops.

How the estate and gift tax system works

The federal estate and gift tax is a single unified system. Every dollar you give away during life or leave at death draws from the same lifetime exemption — the unified credit. In 2026, the annual gift exclusion is $19,000 per recipient ($38,000 for a married couple splitting gifts). Gifts within that annual limit do not count against your lifetime exemption and do not require a gift tax return.

Anything above the annual exclusion chips away at your lifetime exemption. Once the exemption is exhausted, additional transfers are taxed at 40%.

Worked example. A married couple has a combined estate of $16 million. In 2026, the lifetime exemption is approximately $7 million per person ($14 million combined) after the TCJA sunset. Their taxable estate is $16 million minus $14 million = $2 million. At the 40% estate tax rate, that is $800,000 in federal estate tax.

If the same couple had used annual exclusion gifts of $38,000 per year to each of their three children and four grandchildren (7 recipients) for the past five years, they would have moved $38,000 x 7 x 5 = $1,330,000 out of their estate — tax-free, with no exemption used. That alone could reduce their estate tax by roughly $532,000. An estate tax calculator 2026 quantifies exactly how much each gifting strategy saves.

What a good estate and gift tax calculator should show

• Combined estate value versus the applicable lifetime exemption after the 2026 sunset
• Annual exclusion gift capacity across multiple recipients and years
• Projected estate tax liability at the 40% federal rate
• Impact of spousal portability (deceased spousal unused exclusion, or DSUE)
• Generation-skipping transfer tax exposure for gifts to grandchildren or trusts that skip a generation

Cross-reference your results with the Roth Conversion Calculator to evaluate whether pre-paying income tax via Roth conversions reduces the taxable estate, the RMD Calculator to see how required distributions inflate estate value over time, or the IRMAA Calculator to check whether large gifts or conversions push Medicare premiums higher.

Key facts

• Annual gift exclusion (2026): $19,000 per donor per recipient; $38,000 for married couples electing gift splitting.
• Lifetime exemption (2026, post-sunset): approximately $7 million per person / $14 million per couple, indexed for inflation from the pre-TCJA baseline of $5.49 million (2017).
• Estate and gift tax rate: 40% on taxable transfers above the exemption amount.
• Generation-skipping transfer (GST) tax: also 40%, with its own exemption amount equal to the lifetime estate tax exemption.
• Portability: a surviving spouse can elect the deceased spouse's unused exemption (DSUE) by filing a timely estate tax return (Form 706), even if no tax is owed.
• Gift tax return filing threshold: Form 709 is required for any gift to a single recipient exceeding $19,000 in a calendar year, or when electing gift splitting.

Common follow-ups

What is the gift tax exclusion for 2026 and how does gift splitting work? The annual gift exclusion for 2026 is $19,000 per donor per recipient. A married couple can elect gift splitting on Form 709, effectively doubling the exclusion to $38,000 per recipient without using any lifetime exemption. Both spouses must consent, and both must file a gift tax return for the year. Gift splitting applies to all gifts made that year, not selectively — if one spouse gave $30,000 to a child, both returns must report $15,000 each.

How does the unified credit sunset affect estate planning in 2026? The Tax Cuts and Jobs Act roughly doubled the lifetime exemption starting in 2018. That increase is scheduled to expire after December 31, 2025, dropping the exemption from $13.61 million (2024) back to an inflation-adjusted baseline of roughly $7 million per person. The IRS has confirmed an anti-clawback rule: gifts made while the higher exemption was in effect will not be clawed back after the sunset. This means 2024 and 2025 are the last years to make large gifts under the higher limit.

What is the generation-skipping transfer tax and how does the estate planning calculator handle it? The GST tax is a separate 40% tax on transfers to skip persons — typically grandchildren or trusts that benefit them. It has its own exemption, which mirrors the estate tax exemption amount. If you give $3 million to a grandchild trust, that uses $3 million of your GST exemption in addition to $3 million of your lifetime gift tax exemption. An estate planning calculator should track both exemptions separately and flag when a planned gift triggers GST exposure.

Should I gift appreciated assets or cash to minimize estate and gift taxes? Gifted assets carry over the donor's cost basis, meaning the recipient inherits the unrealized gain. Assets passing through an estate, by contrast, receive a stepped-up basis at death. For highly appreciated stock, it may be more tax-efficient to let the asset pass at death (stepped-up basis eliminates capital gains) and gift cash or low-basis assets instead. However, if the goal is to move future appreciation out of the estate — such as funding an irrevocable trust with assets expected to grow significantly — gifting appreciating assets now can freeze the estate value.

When this doesn't apply

Estate and gift tax planning at the federal level is primarily relevant to estates exceeding the lifetime exemption — roughly $7 million per person in 2026 after the TCJA sunset. For estates well below that threshold, federal estate tax is not a concern, though annual exclusion gifts can still be useful for state estate tax planning (several states have exemptions as low as $1 million). This page covers federal rules only. Twelve states plus the District of Columbia impose their own estate tax, and six states have an inheritance tax. Community property and state-specific trust laws add further complexity. Consult a qualified estate planning attorney for state-level analysis.
