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

If you give someone money or property worth more than the annual exclusion amount, you file Form 709 (United States Gift Tax Return) with the IRS. The deadline is April 15 of the following calendar year. You can request an extension to October 15 if you file Form 4868 (Application for Automatic Extension of Time To File U.S. Individual Income Tax Return) by April 15, but the extension covers both your income tax return and your gift tax return together.

The annual exclusion amount changes each year. For 2024, you can give up to $18,000 per person without filing. For 2025, it is $18,000 again. If you give more than that to any one person in a single year, you must report it on Form 709, even if you owe no tax. Married couples can combine their exclusions if they file a joint gift tax return, doubling the amount each can give tax-free.

Key Takeaways

  • Form 709 is due April 15 of the year after you make the gift, matching your income tax deadline.
  • You must file even if you owe no tax, as long as you gave more than the annual exclusion to any one person.
  • The annual exclusion is $18,000 per person for 2024 and 2025, and married couples can each use their own exclusion.
  • An extension to October 15 is available if you file Form 4868 by April 15, but it applies to both income tax and gift tax returns together.
  • Gifts to spouses who are U.S. citizens and gifts to charities do not count toward the exclusion and never require a return.

What counts as a gift for tax purposes

A gift is any transfer of money or property where you receive nothing of equal value in return. This includes cash, real estate, vehicles, investments, artwork, jewelry, and forgiven loans. If you lend someone money and then forgive the debt, the forgiven amount is treated as a gift and counts toward your annual exclusion.

Gifts to your spouse (if they are a U.S. citizen) and gifts to registered charities do not count. Neither do payments you make directly to a school or medical provider on someone else's behalf — those are not considered gifts for tax purposes. Tuition paid directly to the school and medical expenses paid directly to the provider are unlimited and never require a gift tax return.

When you must file Form 709

You must file if you gave more than $18,000 (for 2024 or 2025) to any single person during the year. You file one return per household per year, not one per gift. If you gave $25,000 to your daughter and $15,000 to your son in the same year, you file one Form 709 reporting both gifts.

If you are married and file jointly, both spouses' gifts go on the same return. If you are married and file separately, each spouse files their own Form 709 for their own gifts. If you gave gifts in multiple years, you file a separate Form 709 for each year in which you exceeded the exclusion.

How to file and where to send it

Form 709 is filed with your federal income tax return. If you file your income tax return electronically, you typically file Form 709 electronically as well through the same tax software or tax professional. If you file by mail, you send Form 709 along with your Form 1040 to the IRS address for your state.

You can obtain Form 709 from the IRS website (irs.gov) or request it by phone at 1-800-829-3676. Many tax preparation software programs include Form 709 if you indicate you made gifts over the exclusion amount. A tax professional or CPA can prepare and file the form for you if you prefer not to do it yourself.

What happens if you miss the deadline

If you file late, the IRS may assess penalties and interest on any tax owed. However, if you owe no tax (because your lifetime gift and estate tax exemption has not been used up), the penalty is usually waived if you file within a reasonable time. The IRS defines "reasonable" as generally within three years, though filing as soon as you realize the miss is safer.

If you never file and the IRS discovers the unreported gift, they can assess penalties retroactively. The best approach is to file as soon as you realize you missed the deadline, even if it is years later. The IRS is more likely to work with you on penalties if you file voluntarily than if they find the omission during an audit.

Lifetime exemption and how filing now affects your estate

Filing Form 709 does not mean you owe tax today. Instead, it uses up part of your lifetime exemption — the total amount you can give away during your life and at death before federal gift and estate tax applies. For 2024, your lifetime exemption is $13.61 million. For 2025, it is $13.99 million. These amounts change each year.

When you file Form 709 and report a gift over the annual exclusion, you are using up your lifetime exemption. If you give away $25,000 in one year (exceeding the $18,000 exclusion by $7,000), you use $7,000 of your lifetime exemption. This does not trigger a tax bill now, but it reduces the amount you can pass to heirs tax-free when you die. After 2025, the lifetime exemption is scheduled to drop significantly unless Congress extends current law.

Frequently Asked Questions

Do I have to file if I gave gifts but stayed under the annual exclusion?

No. If you gave $18,000 or less to each person you gave to, you do not file Form 709. The exclusion resets each January 1, so gifts from different years are counted separately. Keep records of what you gave and to whom, in case the IRS asks.

What if my spouse and I give a joint gift — do we each get an exclusion?

Yes, if you file a joint gift tax return. You can each use your own $18,000 annual exclusion, so together you can give $36,000 to one person tax-free. You must both consent to split the gift on Form 709 for this to work. If you are not married or do not file jointly, each person's exclusion is separate.

Can I file Form 709 early, before the April 15 deadline?

Yes. You can file Form 709 any time after the gift is made. Some people file early to document the gift and start using their lifetime exemption sooner. Filing early does not change the tax outcome, but it creates a clear record with the IRS.

What if I gave a gift in 2023 but did not file — can I still file now?

Yes. You can file Form 709 for prior years at any time. The IRS generally does not pursue penalties if you file voluntarily within three years of the original deadline. File as soon as you realize the miss, and include a brief explanation if you want to request penalty relief.

Does my gift affect the person who received it — do they owe tax?

No. The person who receives a gift does not owe income tax on it. Gift tax is paid by the giver, not the receiver. Only you (the person who gave the gift) file Form 709 and potentially use your lifetime exemption.
