Gift Splitting on Form 709: Each Spouse Files Their Own

October 17, 2026 · Informational · Not tax or legal advice

General information, not tax, legal or financial advice. We are not the IRS. Check IRS.gov or a qualified tax professional. Sources read on October 17, 2026. The 2026 Form 709 instructions were still a draft ("DRAFT", dated September 2, 2026) when read, so anything taken from them is expected and must be rechecked against the final version. Examples use made-up numbers. This page contains no affiliate links.

Short answer: to split gifts, you must file a Form 709 even if the gifts are small. A married couple may not file a joint gift tax return: if both spouses consent, gifts either of them make to third parties during the calendar year are treated as made one-half by each, and each spouse files their own Form 709. The instructions suggest filing the two returns together.

Conditions in the draft 2026 instructions (all must apply)

• You and your spouse were married to one another at the time of the gift.
• If divorced or widowed after the gift, you did not remarry during the rest of the calendar year.
• Neither of you was a nonresident who is not a U.S. citizen at the time of the gift.
• You did not give your spouse a general power of appointment over the property interest transferred.

All gifts, not some

The consent is effective for the entire calendar year, so all gifts made by either spouse to third parties during the year (while married) must be split. This includes gifts of property held as joint tenants or tenants by the entirety. If property is transferred partly to your spouse and partly to third parties, the draft says you can only split if the interest going to third parties is ascertainable at the time of the gift.

The consent

Your spouse (the consenting spouse) must sign the Notice of Consent, signed and dated by the consenting spouse, stating that they consent to treat all gifts made to third parties as made one-half by each. Part III of Form 709 is completed if you answer yes to the gift-splitting line (line 19).

Timing

• Consent may generally be signed at any time after the end of the calendar year, but it may not be given after April 15 following the end of the year in which the gift was made. If neither spouse has filed a gift tax return for the year by that date, the consent must be made on the first gift tax return for the year filed by either spouse.
• Consent may not be given after a notice of deficiency for the gift tax for that year has been sent to either spouse.
• How an extension of time to file interacts with the April 15 limit on consent is not addressed in the passages we read.

Only one return?

Only one spouse must file if only one spouse made gifts, the gifts to each person total no more than $38,000, and all were gifts of present interests (a second narrower exception applies; see the instructions). The consenting spouse signs the consent on the donor's return. Filing is still needed to make the consent. Under Regulations section 25.2513-2(a)(1), if only one spouse files within the time provided for consent, the consent of both spouses is signified on that return; showing the notice on both returns is preferable.

Example (made-up numbers)

One spouse gives a niece $30,000 in 2026 and the couple split. The gift is treated as $15,000 from each spouse, each under $19,000. Because the gifts to the niece total no more than $38,000 and the other spouse made no gifts, only the donor needs to file, and the consent is shown on that return.
