Gift tax returns are due by April 15 of the year after you give a gift that exceeds the annual limit

If you give someone a gift larger than the annual exclusion amount, you must file Form 709 (United States Gift Tax Return) with the IRS by April 15 of the following year. The annual exclusion amount changes each year — it was $18,000 per person in 2024 and $19,000 in 2025, but these figures shift with inflation. You file Form 709 even if you do not owe tax; the form straightforward reports the gift to the IRS.

The important date is the same as your income tax important date: April 15. If you file your income tax return early, you do not have to file Form 709 early — it follows the standard April 15 date. If you request an extension on your income tax return (Form 1040), that extension does not automatically extend your gift tax important date, though you can request a separate extension for Form 709.

You only file if the gift exceeds the annual limit for that person in that year. Gifts to your spouse (if they are a U.S. citizen) and gifts to charities have different rules and may not require a return at all.

Key Takeaways

  • Form 709 is due April 15 of the year after you give a gift over the annual exclusion amount, which changes yearly based on inflation.
  • You file the return to report the gift to the IRS, even if you owe no tax because you have not used up your lifetime exemption.
  • An extension on your income tax return does not extend your Form 709 important date unless you request a separate extension.
  • Gifts to your spouse (U.S. citizen) and charitable gifts follow different reporting rules and may not require Form 709 at all.

What counts as a reportable gift

A gift is a transfer of money or property to someone else for which you receive nothing of equal value in return. The annual exclusion applies per person per year, meaning you can give up to the limit to as many people as you want without filing. If you give one person $20,000 in 2025, that $1,000 over the limit must be reported on Form 709.

Certain gifts do not count toward the limit: tuition or medical expenses you pay directly to the provider (not to the person receiving care), gifts to your spouse who is a U.S. citizen, and gifts to charities. Loans between family members may or may not be gifts depending on whether interest is charged and whether repayment is expected — the IRS looks at the actual terms, not what you call it.

How the lifetime exemption works with annual returns

When you file Form 709 to report a gift over the annual limit, you are not necessarily paying tax that year. Instead, you are using part of your lifetime exemption — a total amount you can give away (or leave at death) before federal gift and estate tax applies. In 2025, the lifetime exemption is $13.61 million per person, though this amount is set to drop significantly after 2025 unless Congress changes the law.

Filing Form 709 does not trigger a tax bill; it straightforward records that you have used a portion of your lifetime exemption. The tax is only owed if you exhaust the exemption entirely. Most people never reach that threshold, which is why filing the return is often a formality.

Filing Form 709 with your tax return

You file Form 709 separately from your income tax return (Form 1040), but you send both to the IRS at the same address and on the same important date. You can file Form 709 on paper or electronically through tax software or a tax professional. The form asks for details about each gift: the recipient's name and address, the date of the gift, the value, and your relationship to the recipient.

If you use a tax professional to file your income tax return, let them know you have gifts to report so they can include Form 709 in your filing. If you file on your own, you will need to obtain Form 709 from the IRS website or request it by mail.

What happens if you miss the April 15 important date

If you do not file Form 709 by April 15, the IRS can assess penalties and interest. The penalty for late filing is typically 5% per month of any tax owed, up to 25%, though penalties may be waived if you have reasonable cause. Even if you owe no tax (because you have not exceeded your lifetime exemption), filing late can complicate your records and create questions with the IRS.

If you realize you missed the important date, file Form 709 as soon as you can. Include a brief explanation with your return. The IRS is generally more lenient with late gift tax returns than with late income tax returns, especially if no tax was owed, but filing promptly is still the safest approach.

Requesting an extension for Form 709

You can request an extension to file Form 709 by filing Form 4868 (process for Automatic Extension of Time to File U.S. Individual Income Tax Return) by April 15. This gives you until October 15 to file both your income tax return and Form 709. The extension is automatic — you do not need approval from the IRS, only to file the form on time.

An extension to file is not an extension to pay. If you owe gift tax, it is due by April 15 even if you have an extension to file the return. Interest and penalties accrue on unpaid tax after April 15, so request an extension only if you need more time to prepare the paperwork, not to delay payment.

Gifts to spouses and charities

Gifts to your spouse who is a U.S. citizen are not subject to the annual exclusion limit — you can give your spouse any amount without filing Form 709 or using your lifetime exemption. If your spouse is not a U.S. citizen, a higher annual exclusion applies ($190,000 in 2025), and gifts above that amount must be reported.

Gifts to may have access to charities are also not subject to the annual exclusion and do not require Form 709. Charitable donations are reported on your income tax return (Schedule A if you itemize deductions) instead. If you are unsure whether an organization qualifies as a charity, check the IRS Tax Exempt Organization Search tool on the IRS website.

Frequently Asked Questions

Do I have to file Form 709 if I give someone money but they pay me back later?

If repayment is genuinely expected and documented, it is a loan, not a gift, and Form 709 is not required. However, loans between family members must charge at least the IRS minimum interest rate (which changes monthly) to avoid being treated as gifts. If you lend money with no interest or no repayment expectation, the IRS may treat it as a gift subject to reporting.

What if I give a gift in December but do not know the value until January?

Use the value on the date you gave the gift, not the date you file the return. If the gift was property (like stock or real estate), you may need a professional appraisal to determine the value as of the gift date. File Form 709 by April 15 of the following year using your best estimate; you can amend it later if the value changes significantly.

Can I split a gift with my spouse to avoid filing?

Yes. If you and your spouse agree to split a gift, each of you is treated as giving half, which may keep both gifts under the annual exclusion. You must both consent in writing, and the recipient must be someone other than your spouse. This is called gift splitting and is reported on Form 709.

Do I need to file Form 709 if I give a gift under the annual limit?

No. If your gift to any one person stays under the annual exclusion amount for that year, you do not file Form 709. You only file when a gift to a single person exceeds the limit in a single year.

What if I gave large gifts years ago and never filed Form 709?

You can file Form 709 for prior years at any time. The IRS generally has a three-year window to assess tax, though it can go back longer if you did not file. Filing late returns now prevents the IRS from assessing penalties later and clarifies your lifetime exemption usage. Consult a tax professional if you have unfiled returns from multiple years.
