Form 709 reports gifts exceeding the annual exclusion and allocates generation-skipping transfer tax exemption. Learn when you must file and how gifts.
This guide is designed for first-pass understanding. Start with core terms, then apply the framework in your own account workflow.
Form 709 is the United States Gift Tax Return, required whenever you make gifts that exceed the annual exclusion or that you want to allocate generation-skipping transfer (GST) tax exemption to. With the annual exclusion at $18,000 per recipient for 2024 and the lifetime exemption at $13.61 million, most people never need to file this form. But for those engaged in estate planning, business succession, or significant family wealth transfers, understanding the gift tax system; and Form 709 — is essential.
The federal gift tax was first enacted in 1924, repealed in 1926, and then permanently reenacted in 1932. Its primary purpose was to prevent wealthy individuals from simply giving away their assets during their lifetimes to avoid the estate tax. Without a gift tax, the estate tax would be easily circumvented; you could give your entire fortune to your children the day before you died and owe nothing.
The gift tax and estate tax are now part of a unified transfer tax system. Gifts made during your lifetime that exceed the annual exclusion reduce your available estate tax exemption dollar-for-dollar. Think of it as one large bucket; the lifetime exemption; that gets used up by both taxable gifts and your estate at death.
The annual exclusion was introduced as an administrative convenience to avoid requiring a gift tax return for every birthday present, holiday gift, and casual family transfer. It started at $5,000 in 1932, remained at $10,000 from 1981 through 2001, and has been indexed for inflation since 2002, reaching $18,000 per recipient in 2024.
You must file Form 709 if you made gifts to any one person that exceed the annual exclusion amount ($18,000 for 2024). You must also file if:
The filing deadline is April 15 of the year after the gift is made, the same as the individual income tax return. An extension of time to file your income tax return automatically extends the Form 709 deadline as well. However, the gift tax is due by April 15 regardless of extensions.
An important rule: unlike most tax returns, married couples cannot file a joint gift tax return. Each spouse must file their own Form 709 if they have reportable gifts, even if they elect gift splitting.
In 2024, you can give up to $18,000 per recipient without filing. Married couples can give $36,000 per recipient through gift splitting (though splitting requires filing Form 709). Unlimited gifts are also exempt if made directly to educational institutions for tuition or to medical providers for medical expenses. These exclusions are per-recipient, so you can give $18,000 each to as many people as you want.
Almost certainly not. Filing Form 709 just reports the gift and reduces your lifetime exemption ($13.61M in 2024). You only owe actual gift tax after you've exhausted your entire lifetime exemption. The vast majority of people who file Form 709 never owe a dollar in gift tax — the form simply tracks how much of your exemption you've used.
Form 709 is due April 15 of the year following the gift, the same deadline as your individual income tax return. If you file an extension for your Form 1040, the extension automatically applies to Form 709 as well. However, if you don't need to file a 1040 extension, you must file a separate extension for the gift tax return.

Wills vs Living Trusts: Key Differences and How to Choose
A will takes effect after death and goes through probate. A living trust avoids probate and works during incapacity. Here's a practical comparison and when.
Forgetting to file when gifts exceed the annual exclusion is the most basic error. Some people assume that because they won't owe gift tax (due to the large lifetime exemption), they don't need to file the return. But Form 709 is required to report the gift and reduce the available lifetime exemption, even if no tax is due. Failure to file means the IRS has no record of the gift, which can create complications at death when the estate tax exemption is calculated.
Improper valuation of non-cash gifts is a frequent issue, particularly for gifts of closely held business interests, real estate, and art. The IRS closely scrutinizes valuations on gift tax returns, and inadequate appraisals can result in penalties. Valuation discounts for lack of marketability and minority interests must be reasonable and well-supported.
Failing to elect gift splitting when it would be beneficial is a missed planning opportunity. If one spouse makes a $30,000 gift to a child, only $12,000 is taxable ($30,000 minus the $18,000 exclusion). But if the spouses elect gift splitting, each is treated as giving $15,000, and both gifts are within the exclusion — no taxable gift at all. The election requires both spouses to file Form 709 and consent to split all gifts for the year.
Overlooking the 529 superfunding election is a common oversight. You can contribute up to five years' worth of annual exclusions to a 529 plan at once ($90,000 for an individual, $180,000 for a couple in 2024) without using any lifetime exemption. But you must file Form 709 to make the election and spread the gift over five years for gift tax purposes. If you don't file, the entire contribution may be treated as a current-year gift.
The TCJA's doubled exemption has dramatically increased the amount that can be given away tax-free during your lifetime. With a $13.61 million exemption in 2024, a married couple can transfer $27.22 million without owing any gift or estate tax. This has fueled aggressive gifting strategies as families rush to take advantage of the higher exemption before it potentially sunsets after 2025.
The IRS has confirmed through anti-clawback regulations that gifts made under the current higher exemption will be protected even if the exemption later decreases. This provides certainty for families making large gifts now — they won't face additional estate tax on those gifts if the exemption drops to $7 million.
Direct payments for tuition and medical expenses remain powerful planning tools. Payments made directly to educational institutions for tuition or to medical providers for medical care are unlimited exclusions — they are completely exempt from gift tax and don't reduce your annual exclusion or lifetime exemption. This rule allows grandparents to pay for a grandchild's college tuition without any gift tax consequences, provided the payment goes directly to the school.
The annual exclusion amount continues to be adjusted for inflation. It increased from $17,000 in 2023 to $18,000 in 2024, and is expected to continue rising. Each increase expands the amount that can be given annually without filing Form 709 or using any lifetime exemption.
