Gift tax returns are due on the same day as your income tax return, usually April 15, but only if you gave away more than the annual limit

You file a gift tax return on Form 709 if you gave away money or property worth more than the annual exclusion amount in a single year. The important date is the same as your income tax important date — typically April 15 of the following year. If you file your income tax return late or request an extension, your gift tax return follows the same extension.

The key word here is "if." Most people never file one. The annual exclusion — the amount you can give away tax-free each year — is high enough that only people making large gifts to family members, friends, or charities need to worry about this form. Even then, filing the form does not mean you owe tax. It means you are reporting the gift so the IRS can track it against your lifetime limit.

Key Takeaways

  • Form 709 is due April 15 (or your extended important date) only if you gave away more than the annual exclusion amount to any one person in that calendar year.
  • The annual exclusion amount changes yearly and is set by the IRS — you can find the current year's amount on the IRS website before you file.
  • Filing Form 709 does not mean you owe gift tax; it reports the gift against your lifetime exemption, which is much larger than the annual limit.
  • If you file your income tax return late or get an extension, your gift tax return extension follows automatically — you do not file a separate extension request.
  • Married couples can combine their annual exclusions and lifetime exemptions, but both spouses must consent and report it on the form.

What triggers the requirement to file

You must file Form 709 if you gave away more than the annual exclusion amount to any single person during the calendar year. The annual exclusion is reset each January 1. For example, if the exclusion is $18,000 in 2024, you can give $18,000 to your daughter, $18,000 to your son, and $18,000 to a friend without filing — but if you give $20,000 to one person, you file.

Certain gifts do not count toward the limit at all. Gifts to your spouse (if they are a U.S. citizen) have no limit. Gifts that pay someone's medical bills or tuition directly to the provider also do not count — the payment must go straight to the doctor's office or school, not to the person. Gifts to charities do not count either.

The form itself does not determine whether you owe tax. It reports the gift so the IRS can track it. If your lifetime gifts exceed your lifetime exemption (a much larger number), then you would owe tax. But most people stay well under that limit.

The annual exclusion amount and how to find it

The IRS sets the annual exclusion amount each year, and it changes based on inflation. You can find the current year's amount on the IRS website under "Exclusions" or "Gift Tax" — the number is published by January of each year. The exclusion applies per person, per year, so you can give that amount to as many people as you want without filing.

If you are married, you and your spouse can each give the exclusion amount to the same person in the same year. So if the exclusion is $18,000 and you are married, you can give $36,000 combined to one child without filing — $18,000 from you and $18,000 from your spouse. This is called gift splitting, and both spouses must agree to it and report it on Form 709.

How the lifetime exemption works

Gifts above the annual exclusion do not disappear. Instead, they count against your lifetime exemption — a total amount you can give away over your entire life before owing federal gift tax. The lifetime exemption is much larger than the annual exclusion. When you file Form 709, you are reporting the excess gift and using up part of your lifetime exemption.

For most people, the lifetime exemption is so large that they never reach it. If you do exceed it, you would owe tax on the excess amount. The tax rate is the same as the estate tax rate. However, the lifetime exemption changes with federal law, so the amount you can give away tax-free over your lifetime shifts depending on when you give it.

Filing Form 709 does not trigger a tax bill on its own. It straightforward creates a record that the IRS uses to track your lifetime total. If you never exceed your lifetime exemption, you never owe gift tax, even if you filed the form.

Filing important date and extensions

Form 709 is due on the same date as your federal income tax return. If you file your income tax return on April 15, Form 709 is also due April 15. If you request an automatic extension for your income tax return (using Form 4868), your gift tax return extension is automatic — you do not need to file a separate extension request.

If you miss the important date without an extension, the IRS can assess penalties and interest on any tax owed. However, if you filed your income tax return on time but did not file Form 709, and you did not owe tax on the gift, the penalty is usually smaller or waived if you file the form later. The IRS is more concerned with tracking lifetime gifts than with collecting penalties on forms that do not result in a tax bill.

How to file Form 709

You can file Form 709 by mail or electronically through tax software or a tax professional. The form asks for basic information: your name and Social Security number, the recipient's name and address, the date of the gift, the description of what you gave, and the value of the gift. You will also report whether you are using any of your lifetime exemption.

If you use tax software to file your income tax return, many programs will walk you through Form 709 if you indicate you made gifts above the exclusion. If you work with a tax professional, mention any large gifts when you meet — they will handle the form as part of your return. You file Form 709 with your income tax return, not separately.

Gifts to spouses and charities

Gifts to your spouse have no annual limit and no lifetime limit, as long as your spouse is a U.S. citizen. You do not file Form 709 for these gifts. If your spouse is not a U.S. citizen, there is a higher annual exclusion amount, but you still do not file the standard form — you use a different exclusion and may need to report it.

Gifts to may have access to charities also have no limit. You do not file Form 709 for charitable gifts. However, if you give property (like real estate or stock) to a charity, you may need to file other forms to document the donation for your income tax deduction, but that is separate from gift tax reporting.

Frequently Asked Questions

Do I have to file Form 709 if I gave money to my child but did not exceed the annual exclusion?

No. If your gift to any single person stayed within the annual exclusion amount for that year, you do not file Form 709. You can give that amount to as many people as you want without filing. Only file if you exceed the limit to one person.

What if I gave a gift last year and did not file Form 709 — can I file it now?

Yes. You can file Form 709 for prior years. The IRS prefers you file it, even late, rather than not file at all. Late filing may result in a penalty, but the penalty is often small if no tax was owed. Contact a tax professional to file the prior-year form correctly.

Does my spouse have to file Form 709 if I made the gift?

Only if you are using gift splitting — reporting the gift as if you both made it. If you made the gift alone and did not split it, only you file. If you want to split it, both spouses must agree, and both names appear on the form.

If I file Form 709, do I owe gift tax right away?

Not necessarily. Filing the form reports the gift against your lifetime exemption. You only owe tax if your total lifetime gifts exceed your lifetime exemption. For most people, that never happens. The form is a record, not a tax bill.

What if I gave stock or real estate as a gift — do I report the value I paid for it or what it is worth now?

You report the fair market value on the date you gave it, not what you paid for it. Fair market value is what a willing buyer would pay a willing seller on that date. For stock, use the closing price that day. For real estate, you may need an appraisal. Your tax professional can help you determine the correct value.
