Gift Tax Calculator
Gifts under $18,000 per person per year never trigger a filing. Above that line, the excess draws on your $13,610,000 unified gift-and-estate exemption (rates 18–40%) — a reportable gift, even when no tax is due today.

Gift Tax Analysis
The $82,000 above the annual exclusion is covered by your lifetime exemption, so no check is written to the IRS today (the first $18,000 was tax-free via the annual exclusion). You must still file Form 709 to report the gift, which reduces your remaining lifetime exemption to $13,528,000. This is gifting now to shrink the future estate — the exemption is spent either way.

Giving Money Away Has a Tax Ledger
The federal gift tax is the price of moving wealth to someone else while you are alive. When you give one person more than the annual exclusion — $18,000 in 2024 — the excess becomes a taxable gift that must be reported on Form 709. But reporting and owing are different things: the excess first draws on your lifetime gift-and-estate exemption, a giant shared pool of $13.61 million that also covers whatever you leave at death. Most givers never owe a dollar; they simply spend down that pool. The gift tax matters to US investors for two reasons. First, it is unified with the estate tax, so every dollar gifted now reduces the exemption available later — a decision about when to shrink your taxable estate. Second, the exemption is scheduled to drop roughly in half at the end of 2025, which is accelerating wealthy families' gifting plans. Understanding whether a gift is free (under the exclusion), reportable-but-tax-free (covered by the exemption), or actually taxed (exemption exhausted) is the first step in any wealth-transfer plan — and this calculator draws those three lines precisely.
Exclusion First, Then the Unified Credit
The computation runs three gates in order. Gate one is the annual exclusion: if the gift qualifies, the first $18,000 is removed tax-free and without any filing. The remainder is the taxable gift — the reportable amount. Gate two is the lifetime exemption. Your already-used exemption (from prior Form 709s) is subtracted from the $13.61 million pool to get what remains. The taxable gift fills that remaining space first; the amount that fits is sheltered by the unified credit and costs nothing today, though it does reduce the exemption left for your estate. Gate three handles whatever is left uncovered: it is taxed using the unified rate schedule (18% at the bottom, rising to 40% at the top). The tax itself is computed on the cumulative picture — past taxable gifts plus this one — so a new gift lands at the correct marginal rate, and the unified credit is applied against the sheltered portion.
Expert Insights
The Annual Exclusion Is Per Person, Per Year
The $18,000 limit is per recipient, not per giver, and resets every January. A married couple giving to four grandchildren can move $144,000 a year completely outside the gift-tax system with no filing at all. Repeating this for a decade is a $1.4 million transfer that never touches the lifetime exemption.
Gifting Now Can Beat a Shrinking Exemption
Because the unified exemption is slated to fall sharply after 2025, locking in a large gift before the drop preserves the higher threshold for that amount. The trade is real — giving up control and a stepped-up basis at death — but for families already certain to transfer wealth, using the exemption early is now a common planning move.
Direct Tuition and Medical Payments Are Exempt
Payments made directly to a school for tuition or to a medical provider for care do not count against the annual exclusion or the lifetime exemption at all. Structuring family help as direct payments — rather than handing cash to the relative — is a simple way to move money completely outside the gift-tax ledger.
Actionable Tips
- 1
Stay Under the Line Whenever Possible
Before any gift, check it against the $18,000 per-person limit. If a larger gift is planned, consider splitting it between a spouse's exclusion or spreading it across December and January to use two years of exclusions for the same person.
- 2
File Form 709 Even When No Tax Is Due
Any taxable gift requires a Form 709 for that year, even when the lifetime exemption covers it. Skipping the filing does not eliminate the requirement and can create problems later, so plan to file whenever the gift exceeds the exclusion.
- 3
Track Your Running Exemption Total
Enter everything you have reported on past Form 709s into the lifetime-used field. The tool then shows exactly how much shelter remains and whether your next gift will push into the taxed territory — information worth having before a big transfer, not after.
Real-World Examples
The First-Home Gift
Mia and her husband wanted to give their daughter $60,000 for a down payment. Split between their two exclusions ($36,000), $24,000 remained — a taxable gift. Because they had never used any lifetime exemption, the calculator showed the whole excess was sheltered, so they wrote a small check for $0 and filed Form 709 together. The gift was fully effective with no tax cost.
The Pre-Sunset Acceleration
The Whitfield family planned a $2 million transfer to a trust before the exemption sunset. Their CPA first ran it here with $0 of prior usage, confirming the entire gift would be covered by the exemption and cost $0 today. They filed Form 709 and locked in the higher threshold, then used annual exclusions for smaller ongoing gifts on top.
The Exemption-Exhausted Surprise
A client who had already applied $13.61 million of lifetime exemption across earlier gifts planned one more $250,000 gift, assuming it would be covered. This tool showed his remaining exemption at zero, so the full $250,000 landed in the taxed portion at the 40% top rate — roughly $100,000 owed. He restructured, using direct tuition payments and annual exclusions instead, and deferred the large gift until he was comfortable paying the tax.

- The unified gift-and-estate exemption pool ($13.61 million in 2024) that shelters taxable gifts beyond the annual exclusion and later, property left at death.
