Gift tax returns are due April 15 of the year after you give the gift, the same deadline as your income tax return

The Form 709 (United States Gift Tax Return) is filed with your regular tax return on April 15. If you give a gift that exceeds the annual exclusion amount in any calendar year, you must report it on Form 709 even if you owe no tax. The IRS uses this form to track gifts against your lifetime exemption.

You file Form 709 for the year in which you made the gift. If you gave money or property in December 2024, you report it on the Form 709 you file in April 2025. The deadline does not change based on when in the year you gave the gift — all gifts from that calendar year go on the same return.

Key Takeaways

  • Form 709 is due April 15 of the year following the gift, filed with your income tax return.
  • You must file even if you owe no gift tax, as long as the gift exceeds the annual exclusion for that year.
  • Gifts made in the same calendar year are reported together on one Form 709.
  • If you miss the April 15 deadline, you can file Form 709 with an extension, but the IRS may assess penalties if you owed tax.

What triggers the requirement to file Form 709

You must file Form 709 if you give a gift larger than the annual exclusion amount in a single calendar year. The annual exclusion is the amount you can give to any one person without reporting it or using your lifetime exemption. This amount changes yearly — it was $18,000 per person in 2024 and $19,000 in 2025, but these figures vary by year.

Gifts to your spouse who is a U.S. citizen have no limit and do not require Form 709. Gifts that pay someone's medical bills or tuition directly to the provider also do not count toward the limit. Charitable donations to may have access to organizations do not trigger the requirement either. But gifts of cash, property, or anything else of value to friends, family members, or non-spouse individuals must be reported if they exceed the annual exclusion.

How to file Form 709 on time

File Form 709 with your Form 1040 (your main income tax return) on April 15. You can file both forms electronically through tax software or a tax preparer, or you can print and mail them together. The IRS does not have a separate filing system for Form 709 — it goes to the same address as your 1040.

If you need more time, you can request an extension using Form 4868 (Application for Automatic Extension of Time to File U.S. Individual Income Tax Return). This extends your deadline to October 15. File Form 4868 by April 15 to get the extension. Form 709 is included in the extension — you do not file a separate extension request for the gift tax return.

What happens if you miss the April 15 deadline

If you file Form 709 after April 15 without an extension, the IRS may assess a penalty. The penalty is typically 5 percent per month of any tax owed, up to 25 percent total. If you owed no tax (because the gift was within your lifetime exemption), penalties are usually not assessed, but the IRS may still send a notice asking why you filed late.

Filing late does not erase the gift from your lifetime exemption record. The IRS uses the Form 709 filing date to document when you reported the gift, but the gift itself counts against your exemption in the year you made it, not the year you filed the form. If you gave a large gift and did not file Form 709, the IRS can assess penalties and interest once they discover the unreported gift through an audit.

Lifetime exemption and Form 709

Form 709 tracks gifts against your lifetime exemption, which is the total amount you can give away during your life without owing federal gift tax. In 2024, the lifetime exemption was $13.61 million per person; in 2025 it is $13.99 million. These amounts change yearly and are set by law.

When you file Form 709, you are not necessarily paying tax — you are reporting the gift so the IRS knows how much of your lifetime exemption you have used. If your total gifts stay below the exemption, you owe no tax. If you exceed the exemption during your lifetime, you owe a 40 percent tax on the excess. Form 709 is how the IRS tracks your running total.

Gifts that do not require Form 709

Gifts under the annual exclusion amount do not require Form 709. If you gave $15,000 to one person in 2024, you would not file because it was under the $18,000 limit that year. You can give to multiple people in the same year without filing, as long as each person receives no more than the annual exclusion.

Gifts to your spouse (if a U.S. citizen), direct payments of medical expenses or tuition to providers, and donations to may have access to charities also do not require Form 709. Inheritances do not count as gifts and do not trigger the form. If you are unsure whether a particular gift requires reporting, a tax preparer or the IRS can clarify based on the amount and type of gift.

Filing an amended Form 709

If you filed Form 709 but made an error, you can file an amended return using Form 709-A (Statement of Certain Gifts Made During Previous Years). File this form with your amended income tax return (Form 1040-X) if you need to correct information about gifts you reported in prior years.

You have three years from the original filing date to file an amended Form 709 without the IRS initiating an audit. After three years, the IRS can still assess penalties if they discover unreported gifts, but you have limited ability to correct the record yourself. If you realize you missed filing Form 709 in a prior year, file it as soon as possible along with Form 1040-X for that year.

Frequently Asked Questions

Do I file Form 709 every year even if I do not give gifts?

No. You only file Form 709 in years when you give gifts that exceed the annual exclusion. If you give no gifts or give only small gifts under the limit, you do not file the form that year. There is no annual requirement to file unless you have a reportable gift.

What if I give a gift in December but do not file until the following April?

That is the normal process. Gifts made in December 2024 are reported on the Form 709 filed in April 2025. The year of the gift is what matters for reporting, not the year you file the form. The IRS expects you to report the gift in the tax year following the year you made it.

Can I file Form 709 without filing an income tax return?

Generally, no. Form 709 is filed with your Form 1040. If you have no income tax filing requirement, you may still need to file Form 709 to report large gifts, but you would file both forms together. Consult a tax preparer if you have no income but made reportable gifts.

What if my spouse and I give a gift together — do we file one Form 709 or two?

If you are married and file jointly, you file one Form 709 together. If you file separate returns, each spouse files their own Form 709 for gifts they made. Gifts from joint accounts are typically split between spouses for reporting purposes.
