Form 709 Explained: When You Must File a US Gift Tax Return

That's the part people miss: filing Form 709 and owing gift tax are two different things. The return is how the IRS keeps score against your lifetime exclusion. Facts below are from the IRS's 2025 instructions and its estate and gift tax update page.

The key numbers

Year	Annual exclusion per person	Basic exclusion amount
2024	$18,000	$13,610,000
2025	$19,000	$13,990,000
2026	$19,000	$15,000,000

The IRS says the July 2025 law (Public Law 119-21) raised the basic exclusion amount to $15,000,000 for 2026. Figures are as of October 2026.

Who must file Form 709

• You gave someone other than your spouse gifts totalling more than the annual exclusion in the year.
• You made a gift of a future interest, of any size. Future interests don't get the annual exclusion.
• You and your spouse want to split gifts, whatever the amount. Gift splitting needs a return.
• You gave community property, or property you held as joint tenants or tenants by the entirety. Each spouse files.

Spouses can't file a joint gift tax return; each person files their own. Only individuals file, so if a trust, estate, partnership or corporation makes a gift, the beneficiaries, partners or shareholders are treated as the donors.

Who doesn't need to file

You can skip Form 709 if all three are true: you made no gifts to your spouse, you didn't give more than the annual exclusion to any one person, and every gift was a present interest. Gifts only to qualifying charities don't need a return either, as long as you gave your entire interest in the property.

Gifts that aren't counted at all

Two exclusions sit on top of the annual one. Tuition you pay directly to a qualifying school, college or university for someone else isn't subject to gift tax. Neither are medical expenses you pay directly to the provider. The word that matters is directly: hand the cash to your grandchild and they pay the bill, and it's an ordinary gift.

Other transfers the gift tax ignores, and one it doesn't

• Transfers to a political organization for its own use aren't subject to gift tax.
• Neither are transfers for the use of certain exempt groups: civic leagues, labor, agricultural or horticultural organizations and business leagues that are tax-exempt.
• Crypto and NFTs aren't a loophole. The instructions say the gift tax applies to digital assets, including virtual currencies such as cryptocurrencies and stablecoins.

So if you hand a relative some Bitcoin worth more than the annual exclusion, that's a reportable gift exactly like cash.

Gifts to a spouse who isn't a US citizen

Gifts to a US citizen spouse don't need a return unless they're a terminable interest outside the IRS exception, or you're making the QTIP election. If your spouse isn't a US citizen, you only need to file when your gifts of present interests to them in the year total more than $190,000, or if you gave them any future interest. That's the 2025 figure in the instructions as of October 2026.

Deadlines and extensions

1. File between January 1 and April 15 of the year after the gift. If April 15 falls on a weekend or legal holiday, it's the next business day.
2. An extension for your income tax return, for example with Form 4868, automatically extends the time to file Form 709 too.
3. Neither type of extension gives you more time to pay any gift or GST tax. That needs a separate request.
4. If the donor died during the year, the executor files by the earlier of the estate tax return due date (with extensions) or April 15 (or the extended gift tax due date).

You can now e-file Form 709 through the IRS's Modernized e-File system, which the IRS lists on its estate and gift tax page.

Who pays if there's tax to pay

The donor is responsible for paying the gift tax. If the donor doesn't pay, the person who received the gift may have to. With a basic exclusion of $15,000,000 for 2026, a return often just records the gift against what's left, but it still matters: it's the record of lifetime gifts your executor will need later.

A worked example from the IRS

The instructions use a 529 plan (a qualified tuition program) to show the five-year election. In 2025, Pat puts $100,000 into a 529 for Max and elects to treat $95,000 of it as made evenly over five years. For 2025, Pat reports $24,000 for Max: the $5,000 above $95,000 plus the first $19,000 slice.

In 2026, Pat gives Alex $20,000 in cash, which is over the annual exclusion, so Pat files. That 2026 return shows the $20,000 to Alex and the next $19,000 slice for Max. Pat makes no gifts in 2027, 2028 or 2029 and doesn't need to file in those years just to report the remaining slices, because nothing else requires a return.

If you'd rather hand the paperwork to a professional, a Form 2848 lets them deal with the IRS for you.

The verdict

If you give anyone other than your spouse more than $19,000 in a year, file Form 709 by April 15 even when no tax is due. It costs nothing, protects the record of your lifetime exclusion and saves your family a headache later. Pay tuition and medical bills directly whenever you can, because those never count.

Frequently asked questions

Do I owe gift tax if I file Form 709?

Usually not. Filing records the gift against your lifetime exclusion, which the IRS says is $15,000,000 for 2026 as of October 2026.

Can my spouse and I file one Form 709?

No. Spouses can't file a joint gift tax return, and you each file your own if you split gifts.

What's the annual gift exclusion for 2026?

As of October 2026 the IRS lists $19,000 per recipient for 2026, the same as 2025.

Does paying my grandchild's tuition count as a gift?

Not if you pay a qualifying school directly for tuition. Giving the cash to the grandchild to pay it makes it an ordinary gift.
