Gift Splitting for Married Couples: IRC §2513 Rules and Form 709

Gift splitting for married couples is an election under Internal Revenue Code §2513 that lets a couple treat a gift made by one spouse to a third party as if each spouse made half of it. In 2026, that doubles the annual gift tax exclusion from $19,000 to $38,000 per recipient, and it lets both spouses’ lifetime exemptions absorb any excess.¹ The election is made on Form 709, and both spouses must consent in writing.

How the Election Works

Under 26 U.S.C. §2513, when one spouse gives property to anyone other than the other spouse, the couple can elect to have the IRS treat the gift as made one-half by each spouse.² The election is a tax fiction. The donor does not have to transfer money to the other spouse first, and the recipient does not need to know that splitting happened. All of it lives on the return.

Say one spouse writes a $38,000 check to an adult child in 2026. Without gift splitting, $19,000 falls under the donor’s annual exclusion and the other $19,000 is a taxable gift that reduces the donor’s lifetime exemption. With gift splitting, each spouse is treated as giving $19,000, both halves fall within the annual exclusion, and neither spouse uses any lifetime exemption.

The Doubled Exclusion and Combined Lifetime Exemption

The 2026 annual exclusion is $19,000 per donor per recipient.³ Splitting doubles that to $38,000 per recipient because two exclusions now apply to what was a single gift.

When a split gift exceeds the combined annual exclusions, the excess is divided equally and each half counts against that spouse’s own lifetime exemption. The 2026 basic exclusion amount is $15,000,000 per individual after the amendments in the One, Big, Beautiful Bill signed in July 2025.⁴ A couple that splits gifts has a combined $30,000,000 of lifetime exemption available before any gift tax becomes due. Each spouse tracks their own usage on their own Form 709. Clean records matter if either spouse remarries or their estate later claims what remains.

Who Can Elect It

Three conditions have to be met. The spouses must be legally married when the gift is made.² Neither can remarry before the end of the calendar year. And both must be U.S. citizens or residents at the time of the gift. If one spouse is a nonresident alien, the couple cannot split gifts at all. A separate rule allows an increased annual exclusion of $194,000 in 2026 for gifts made directly to a non-citizen spouse, but that is a different mechanism.³

Divorce or Death During the Year

If a couple divorces partway through the year, the election covers only gifts made while they were still married. Gifts made after the divorce is final cannot be split.⁵ The same logic applies when one spouse dies: gifts made before death can be split, but the surviving spouse cannot remarry before December 31 and still use the election for that year.² When a spouse has died, the executor or the legal guardian of a legally incompetent spouse can sign the consent on their behalf.⁶

Community Property States

In community property states, gifts from community property are already treated as coming half from each spouse by default, so the election is unnecessary for those assets. If one spouse gifts their separate property, the couple can still elect to split that gift. The line between community and separate property matters, so couples in these states should be precise about which funds were used.

Gifts You Cannot Split

Splitting only works for transfers to third parties. A gift from one spouse directly to the other is not eligible, though those transfers are generally covered by the unlimited marital deduction anyway.

The statute also blocks splitting when the donor gives the other spouse a general power of appointment over the gifted property.² A general power of appointment means the spouse could redirect the property to themselves, their creditors, or their estate. This comes up most often with irrevocable trusts where the drafter inadvertently gives the non-donor spouse too much control.

The All-or-Nothing Rule

Couples cannot cherry-pick which gifts to split. If they elect gift splitting for any gift made during the year, the election applies to every gift both spouses made to third parties during the entire time they were married that year.⁷ This is where the election can hurt. If one spouse made a large gift the other did not know about, consenting to split means both spouses share the tax consequences of that gift too. Compare notes on every gift made during the year before either spouse signs.

Joint and Several Liability

The consenting spouse is not just doing paperwork. By signing the consent, both spouses become jointly and severally liable for the entire gift tax owed by either spouse for that year.² The IRS can collect the full bill, including penalties and interest, from either spouse individually. This liability survives divorce. If you consent to split gifts in 2026 and divorce in 2028, the IRS can still come after you personally if your ex-spouse does not pay.

Filing Form 709

When a Return Is Required

You must file a gift tax return to elect gift splitting, even if every gift falls below the annual exclusion and no tax is owed.⁷ This catches many couples off guard. If you gave your daughter $30,000 and want to split so each spouse is treated as giving $15,000, you still need to file the return to make the election valid. Without the filing, the IRS has no record of the split, and the full $30,000 is attributed to the donor spouse.

Whether both spouses have to file depends on the gifts. If only one spouse made gifts, every gift was a present interest, and no single gift exceeded $38,000, generally only the donor spouse files, with the other spouse’s signed Notice of Consent attached. When either spouse’s gifts exceed those thresholds, or both spouses made gifts, each spouse files their own Form 709 with the other’s consent attached.⁷

What Goes on the Return

Form 709 is formally the “United States Gift (and Generation-Skipping Transfer) Tax Return.”⁸ The donor reports the full value of each gift on Schedule A, with columns for the date of the gift and its value at that date.⁹ The half attributed to the consenting spouse goes in a separate “Split Gifts” column. Both spouses’ full legal names and Social Security numbers are required.

Cash is easy to value. Real estate, business interests, and art require fair market value at the time of transfer, and for real estate a qualified appraisal is effectively mandatory to substantiate the reported value. Keep the bank statements, brokerage reports, and appraisals with the return.

The Consent

The consenting spouse’s agreement appears in Part III of Form 709, “Spouse’s Consent on Gifts to Third Parties.”⁹ The IRS instructions also require a signed Notice of Consent attached to the donor’s return, stating that the consenting spouse agrees to treat all gifts made to third parties during the year as made one-half by each spouse, with signature and date.⁶

Deadlines, Extensions, and Revocation

Form 709 is due April 15 of the year after the gift. An automatic six-month extension of your Form 1040 also extends your gift tax return.¹⁰ The gift tax return is a separate filing and is not attached to your income tax return.

Consent to split gifts cannot be signed after April 15 following the year of the gift, unless neither spouse has filed a gift tax return for that year by that date. In that case, the consent must appear on the first return filed by either spouse. Consent cannot be given after the IRS sends a notice of deficiency to either spouse for that year.²

Revocation is tight. If consent was signed on or before April 15, it cannot be revoked after that date. If consent was signed after April 15 (because no return had been filed yet), it cannot be revoked at all.² The window to change your mind is short.

Late Filing Penalties

Filing Form 709 late without an extension triggers a penalty of 5% of the unpaid tax for each month the return is overdue, up to 25%.¹¹ Even when no tax is due, filing late causes problems downstream. The IRS’s ability to question a gift’s value is limited to three years after a return is filed with adequate disclosure. If you never file, or file without enough detail, no limitation period runs, and the IRS can revisit the gift decades later.

Keeping Records

Gift tax records deserve more care than most tax documents. The general rule for income taxes is three years, but any gift that was not adequately disclosed on a filed return has no statute of limitations, which means the IRS could question a gift 20 or 30 years later when your estate files its final return. Keep a complete copy of every Form 709 you file, all supporting appraisals, and proof of mailing for as long as the gifts could be relevant to your estate. In practice, that means indefinitely.
