Form 709

Form 709 is the Internal Revenue Service form on which an individual reports gifts made during a calendar year and figures any gift tax and generation-skipping transfer tax due on them. The instructions state its purpose in two parts: to report "transfers subject to the federal gift and certain generation-skipping transfer (GST) taxes and to figure the tax due, if any, on those transfers," and to report the "allocation of the lifetime GST exemption to property transferred during the transferor's lifetime."

The distinction worth holding onto is between the form and the tax. The gift tax is the levy and the reasons almost nobody pays it are covered on its own page; Form 709 is the document, and the document is required in a wider set of circumstances than the tax is. The instructions put it plainly: a citizen or resident "must file a gift tax return (whether or not any tax is ultimately due)" in the listed situations. A reader who arrives asking "do I owe gift tax?" is usually asking the wrong question. The question the form answers is whether a return is required.

Who must file, including the cases that surprise people. The instructions list the triggers, and four of them catch filers who expected to be outside the system entirely.

• Gifts over the annual exclusion. Gifts to any one person totaling more than $19,000 in the year, other than to a spouse, generally require a return.
• A future interest, at any value. Verbatim: "Certain gifts, called future interests, are not subject to the … annual exclusion and you must file Form 709 even if the gift was under" the exclusion. The instructions go further and say you must "always enter all gifts of future interests that you made during the calendar year regardless of their value." A gift into a trust that the beneficiary cannot reach now is the ordinary way an unremarkable transfer becomes a reportable one.
• Splitting a gift with a spouse, regardless of amount. A return is required "to split gifts with your spouse (regardless of their amount)."
• Community property and joint tenancy. A gift of community property "is considered made one-half by each spouse," so a $100,000 gift is a $50,000 gift from each and each spouse must file. The same applies to a gift of property the spouses hold as joint tenants or tenants by the entirety.

Spouses cannot file jointly, and this is the one place the tax system refuses to treat a married couple as a unit. The instructions say it twice, once in Who Must File and again as a caution on the form itself: "Spouses may not file a joint gift tax return. Each individual is responsible to file a Form 709." Marriage neither merges the two donors nor doubles anything on the return. What it does offer is the gift-splitting election below, which is a different mechanism reached by a different route.

Only individuals file it. Where "a trust, estate, partnership, or corporation makes a gift, the individual beneficiaries, partners, or stockholders are considered donors and may be liable for the gift and GST taxes." The donor is responsible for the tax, but the instructions add a point rarely noticed: "if the donor does not pay the tax, the person receiving the gift may have to pay the tax." And if a donor dies before filing, the executor files.

The gift-splitting election, and the 2025 change to how consent is given. Section 2513 lets spouses treat gifts to third parties as made one-half by each, which is what allows a couple to shelter twice the annual exclusion per recipient from a single spouse's assets. The election is made on the return. In the 2025 revision of the form the mechanics moved: lines 12 through 18 left Part I for a new Part III, "Spouse's Consent on Gifts to Third Parties," on page 2, and the instructions state that "a consenting spouse is no longer required to sign the return but must sign a Notice of Consent to be attached to the donor's return." Any description of the spouse signing Part I is describing the older form. The consent generally may be signed at any time after the calendar year ends, but not after April 15 following the year of the gift, subject to two exceptions in the instructions.

The GST half of the title is narrower than it looks. Verbatim: "The GST tax you must report on Form 709 is that imposed only on inter vivos direct skips." An inter vivos direct skip is a transfer that is subject to the gift tax, of an interest in property, and made to a skip person, and all three conditions must be met. The other two kinds of generation-skipping transfer go elsewhere: a taxable termination on Form 706-GS(T), a taxable distribution on Form 706-GS(D), and a death-time skip on Form 706, the estate tax return. Form 709 is nonetheless where lifetime GST exemption is allocated, which is why a return can be required in a year with no tax and no exclusion consumed at all.

The other elections only this form can carry. The three special-valuation elections under section 2701 "you can make only with Form 709," and all of them may be revoked only with the consent of the IRS. Electing out of the automatic allocation of GST exemption happens here. So does the section 2652(a)(3) election, which became a checkbox column on Schedule A in the 2025 revision. And a surviving spouse's use of a deceased spouse's unused exclusion is reported on Schedule C. This is the practical reason the form matters more than its filing frequency suggests: several irrevocable choices have no other home.

A new companion form. Also new for 2025 is Form 709-NA, "United States Gift (and Generation-Skipping Transfer) Tax Return of Nonresident Not a Citizen of the United States," for a nonresident non-citizen who gave real or other tangible property situated in the United States.

Two procedural notes that cost people real money. The instructions warn that "returns filed without entries in each field will not be processed," so a return left partly blank is not a late-but-filed return. And the adequate-disclosure rules matter: a gift disclosed adequately on a filed return starts the assessment clock, while an undisclosed gift leaves the year open. Section 6651 imposes penalties for both late filing and late payment absent reasonable cause.

A donor lists every reportable gift made during the calendar year on one return, computes taxable gifts on Schedule A, adds them to the running total of prior taxable gifts, applies the unified credit, and files by April 15 of the following year. All gifts for a year go on a single Form 709; the instructions are explicit that you "do not file more than one Form 709 for the same calendar year."

The deadline and the two extension routes, which are separate from the time to pay. Section 6075(b)(1) sets the date as April 15 following the close of the calendar year, moving to the next business day where that falls on a weekend or legal holiday. There are two ways to extend the filing date, and the instructions state the shared limit first: "Neither method extends the time to pay the gift or GST tax."

1. Automatically, with the income tax extension. Section 6075(b)(2) deems any extension granted for the calendar-year income tax return to be an extension for the gift tax return as well, using Form 4868 or Form 2350. The catch is stated verbatim: "You may only use these forms to extend the time for filing your gift tax return if you are also requesting an extension of time to file your income tax return."
2. On its own, with Form 8892, "Application for Automatic Extension of Time To File Form 709 or Form 709-NA and/or Payment of Gift/Generation-Skipping Transfer Tax," which requests an automatic six-month extension and doubles as a payment voucher.

An extension of time to pay must be requested separately, under Regulations section 25.6161-1.

The deadline in the year the donor dies moves earlier, not later. Section 6075(b)(3) provides that the gift tax return for the calendar year including the date of death "shall not be later than the time (including extensions) for filing" the estate tax return. The instructions state the resulting rule as a comparison: the executor files not later than the earlier of the due date with extensions for the estate tax return, or the ordinary April 15 date or extended date for the gift tax return. Reading only the estate-tax half of that rule makes the deadline look more generous than it is.

A hypothetical, to show how the filing question separates from the tax question. Suppose that during one calendar year Dolores makes four transfers. She pays $28,000 directly to her granddaughter's university for tuition. She gives her nephew a $14,000 car. She and her husband Ray agree to treat a $60,000 gift to their daughter, made entirely from Dolores's own account, as made one-half by each. And she funds a trust with $9,000 that her son cannot touch until he turns forty.

Working through them: the tuition paid straight to the school is a qualified transfer under section 2503(e) and is not a gift for these purposes at all, so it is not reported. The car is a present-interest gift below the annual exclusion and needs no return. The $60,000 to the daughter is the one that forces the filing, and it forces two returns rather than one: the gift-splitting election requires a return "regardless of their amount," so Ray must file as well even though he transferred nothing, and each of them is treated as giving $30,000. The trust funding is a future interest, so it is reportable at $9,000 despite being well under the annual exclusion. Dolores files one Form 709 reporting the $30,000 half-gift and the $9,000 future interest; Ray files one reporting his $30,000 half. Neither of them owes gift tax, because the amounts above the annual exclusion reduce lifetime exclusion rather than producing a bill. Two returns, no tax, and the only transfer anyone would have called large is the one that generated no paperwork at all.

What filing does for you

• It is the only record of how much lifetime exclusion has been used, and that figure is needed decades later when an estate is settled.
• Adequate disclosure on a filed return starts the clock on the IRS's time to challenge the gift's value. An undisclosed gift leaves that year open.
• It is the sole route to several irrevocable elections: gift splitting, allocating or electing out of GST exemption, the section 2701 valuation elections, the section 2652(a)(3) election, and claiming a deceased spouse's unused exclusion.
• Filing when the position is arguable is cheaper than defending an unreported gift, since the penalty exposure under section 6651 runs from the original deadline.

The costs and traps

• Spouses cannot file jointly, so the gift-splitting election that saves tax usually doubles the paperwork — both spouses file their own return unless one of the instructions' two amount-based exceptions applies.
• A future interest is reportable at any value, which catches ordinary trust funding that no one thought of as a taxable gift.
• A return with blank fields "will not be processed," so an incomplete filing does not stop the late-filing clock.
• Valuing a gift of anything other than cash or listed securities generally means an appraisal or a documented valuation method, and discounts have to be explained on the return.
• Neither extension route buys time to pay, and the extension is available through your income tax return only if you are extending that return too.
