Giving money to family is generous, but the IRS keeps a tally. The federal gift tax exists so wealthy people cannot give away their entire fortune during life to escape the estate tax — yet for the vast majority of gifts, no tax is ever actually paid. This gift tax calculator walks you through exactly how much of your gift is tax-free, how much (if anything) you owe today, and how much of your lifetime exemption you have used.
The key idea: every year you can give each person up to the annual exclusion without reporting it at all. Anything above that is a "taxable gift," but it still usually costs you nothing out of pocket — it simply chips away at the $13.61 million lifetime exemption that protects your estate at death. Only once that lifetime exemption is fully used does real cash tax come due, at a top rate of 40%.
How to Use
- Enter the Gift Amount — the total value of cash, stocks, real estate, or property you gave to a single recipient this year.
- Check the Annual Exclusion per Donee. For 2024 it defaults to $18,000 per person; for 2025 the IRS raised it to $19,000. Adjust it if you are calculating for a different tax year.
- Fill in Prior Taxable Gifts with the cumulative taxable gifts you have already reported on Form 709 in earlier years. If you have never filed Form 709, leave this at $0.
- Confirm the Lifetime Gift Tax Exemption. The 2024 figure is $13.61 million per person; under current law it is scheduled to drop to roughly $7 million on January 1, 2026, so adjust it if your planning horizon crosses that date.
The result card shows the portion covered by the annual exclusion, the taxable remainder, how much lifetime exemption that taxable gift consumes, the exemption you still have left, and — only when the numbers force it — the gift tax you would actually owe today.
How the Gift Tax Math Works
The calculation follows the IRS Form 709 worksheet in three layers:
Layer 1 — Annual exclusion. You subtract the annual exclusion from the gift. A $50,000 gift to one person in 2024 leaves $50,000 − $18,000 = $32,000 of taxable gifts. This exclusion applies separately to every recipient: the same $50,000 split as $25,000 to two children produces only $7,000 + $7,000 = $14,000 of taxable gifts, not $32,000. Gifts between married couples who are both U.S. citizens are fully deductible and never touch this calculation.
Layer 2 — Lifetime exemption. The taxable $32,000 is then shielded by your unified lifetime exemption. With no prior gifts, you still have the full $13.61 million available, so the entire $32,000 is absorbed by the exemption. You owe $0 today, but your remaining exemption drops to $13,610,000 − $32,000 = $13,578,000. That is the part people misunderstand: making a taxable gift does not mean paying tax now — it means prepaying a tiny drawdown on the tax-free amount you can leave at death.
Layer 3 — Tax above the exemption. Only when cumulative taxable gifts exceed the lifetime exemption does the excess get taxed, at graduated rates topping out at 40%. If you had already used the entire $13.61 million exemption through prior gifts and then gave another $2,000,000, the taxable amount above exclusion is $1,982,000, and the tax owed immediately is $1,982,000 × 40% = $792,800.
Examples
Example 1 — The classic $50,000 gift. You give an adult child $50,000 in 2024 and have never filed Form 709. The first $18,000 is covered by the annual exclusion; the remaining $32,000 is a taxable gift, but it fits entirely inside your unused $13.61 million lifetime exemption. Tax owed today: $0. Your remaining lifetime exemption becomes $13,578,000, and you must file Form 709 to report the $32,000 even though nothing is due.
Example 2 — Splitting the same gift across two people. You give $25,000 to each of two children. Each $25,000 gift has $18,000 excluded, leaving $7,000 taxable per child, or $14,000 total. Once again the exemption absorbs it, so tax owed: $0, and you consume only $14,000 of your lifetime exemption instead of $32,000. Spreading gifts among more recipients is the single easiest way to stay entirely off Form 709.
Example 3 — A large gift after the exemption is exhausted. You have already used the full $13.61 million exemption through prior gifting, and you transfer $2,000,000 to a trust. After the $18,000 annual exclusion, $1,982,000 is taxable with no exemption left, producing an immediate federal gift tax of $792,800. Gifts this large are usually paired with GRATs, charitable trusts, or 529 plans instead.
FAQ
Do I actually owe gift tax on money I give my kids?
Almost certainly no. In 2024 you can give each person up to $18,000 completely tax-free, and even above that the gift is only "taxable" in the sense that it draws against your $13.61 million lifetime exemption. You owe no out-of-pocket tax until your cumulative taxable gifts exceed that entire exemption.
Do I need to file Form 709 for a gift over the annual exclusion?
Yes. Once a gift to any one person exceeds the annual exclusion ($18,000 in 2024), you must file Form 709 even if no tax is owed. Filing starts the statute of limitations and formally records how much of your lifetime exemption you have used. Gifts at or below the annual exclusion require no filing at all.
How much can I give tax-free in one year?
You can give $18,000 (2024) or $19,000 (2025) to as many people as you want — it is per recipient, not per year total. A married couple can together double that to $36,000 (2024) per person. Paying someone's medical bills or tuition directly to the institution does not count against the exclusion at all.
What is the lifetime gift tax exemption in 2024?
The 2024 federal lifetime gift and estate tax exemption is $13.61 million per person, or $27.22 million per married couple. Under current law this amount is scheduled to sunset on January 1, 2026, dropping to roughly $7 million adjusted for inflation, which is why many advisors are rushing large gifts through in 2024 and 2025.
Who pays the gift tax — the giver or the recipient?
The donor (giver) is legally responsible for the gift tax. In rare cases where the donor does not pay, the recipient may be liable under a special provision. Recipients never owe income tax on gifts, regardless of size.
Are gifts to a spouse or charity taxable?
No. Gifts between U.S. citizen spouses are fully deductible with no limit, and gifts to qualified 501(c)(3) charities are also unlimited and tax-free. The annual exclusion and lifetime exemption apply only to gifts you make to people who are not your spouse or a charity.
