Do You Owe Gift Tax on a Down Payment Gift?

If a relative gives you money to help buy a home, you owe no federal tax on it. Gift tax on a down payment is the donor’s concern, not yours, and even the donor rarely pays anything: the IRS lets any person give up to $19,000 to any other person in 2026 with no filing at all, and a $15 million lifetime exemption absorbs almost everything above that. What both sides do need to handle is paperwork — one form for the IRS in some cases, and a stack of documents for the mortgage lender in every case.

Who Actually Owes the Tax

Federal gift tax is imposed on the person transferring the money, not the person receiving it.¹ If your parents write you a check for $60,000 toward closing, you report nothing as income and owe nothing. Any reporting obligation lives with them.

Two layers keep almost every down payment gift out of actual tax:

The annual exclusion. For 2026, one person can give any other person up to $19,000 in a calendar year with no IRS filing whatsoever.²
The lifetime exemption. Amounts above the annual exclusion reduce the donor’s lifetime estate and gift tax exemption, which sits at $15 million per individual for 2026. No cash is owed to the IRS until cumulative lifetime gifts pass that ceiling.³

Put those together with a common scenario. A parent gives an adult child $50,000 in 2026 for a down payment. The first $19,000 disappears into the annual exclusion. The remaining $31,000 chips away at the parent’s lifetime exemption, leaving $14,969,000 still available. The parent files a return but writes no check. Actual gift tax, at rates topping out at 40%, only kicks in once a donor has given away more than $15 million over a lifetime.

How Families Multiply the Exclusion

The $19,000 figure is per donor, per recipient, per year. That single sentence does most of the planning work for a down payment gift.⁴

A married couple can elect to split a gift, treating it as if each spouse contributed half even when only one wrote the check. That doubles the annual exclusion to $38,000 per recipient for 2026.² Gift splitting requires both spouses to file Form 709 and consent to split all gifts for that calendar year, and the election cannot be undone after the filing deadline.

Now stack the recipients. Two parents giving to a married child and that child’s spouse can move up to $76,000 in a single year without any filing: each parent gives $19,000 to the child and $19,000 to the child’s spouse. Add a grandparent or a second set of parents, and a substantial down payment can arrive with no Form 709 in sight. Timing matters too. A gift on December 31 and another on January 2 fall in different tax years and each get their own annual exclusion.

When the Donor Must File Form 709

Form 709, the United States Gift (and Generation-Skipping Transfer) Tax Return, is required whenever a donor’s gifts to a single recipient in one year exceed the $19,000 annual exclusion, and whenever a married couple elects gift splitting.²

The return is due April 15 of the year following the gift. A donor who files a federal income tax extension automatically gets the same extension for Form 709; no separate request is needed.⁵

On the form, the donor subtracts the $19,000 annual exclusion from the total gift and applies the remainder against the $15 million lifetime exemption.³ Keep copies of every Form 709 ever filed. Tracking the running total is how the donor’s estate will know years later how much exemption is left.

Why File When No Tax Is Owed

Skipping a required Form 709 quietly creates a long-term problem. If a gift is not adequately disclosed on a timely return, the IRS can assess gift tax on that transfer indefinitely. Filing with adequate disclosure starts a three-year clock, after which the return is closed.⁶ Filing is the cheap protection for the donor’s later estate plan.

What the Mortgage Lender Will Want

The IRS side is often the easy side. The lender’s requirements are separate, and they exist to make sure the down payment is a gift and not a hidden loan that would change the borrower’s debt-to-income ratio.

The Gift Letter

Every lender requires a signed gift letter from the donor. At minimum it needs to include:

The donor’s name, address, and phone number
The donor’s relationship to the borrower
The dollar amount of the gift
A clear statement that no repayment is expected or required

For conventional loans sold to Fannie Mae, eligible donors include relatives by blood, marriage, adoption, or legal guardianship, along with non-relatives who have a familial-type relationship such as a domestic partner. The donor cannot be the builder, developer, real estate agent, or anyone else with a financial interest in the transaction.⁷ FHA loans generally limit donors to family members.⁸

Tracing the Money

The lender will want documentation showing the money’s path from donor to borrower. Acceptable proof includes a copy of the donor’s check with the borrower’s deposit slip, an electronic transfer record between the two accounts, or a settlement statement showing the closing agent received the funds directly from the donor.⁷ Expect to hand over the donor’s bank statement so the lender can confirm the funds were actually available in that account. A cashier’s check works, but the receipt showing the donor as purchaser needs to come with it.

Gifts of Equity

A relative can also give the down payment by selling their home to the buyer below market value. The gap between the sale price and the appraised value is treated as a gift and can serve as part or all of the down payment. FHA loans allow gifts of equity only from family members and require the same signed gift letter.⁸ Fannie Mae also permits gifts of equity and does not treat the donor-seller as an interested party in the transaction.⁷

The tax treatment mirrors a cash gift. The seller-donor is the one potentially subject to gift tax on the discount, and if that discount exceeds $19,000 to a single buyer, the donor files Form 709 and applies the excess to their lifetime exemption.

The Family Loan That Turns Into a Gift

Some families would rather lend the down payment money than give it. That is fine, but the arrangement has to look like a real loan. If a family loan charges no interest or a rate below the IRS Applicable Federal Rate, the IRS treats the forgone interest as a gift from lender to borrower.⁹ Loans of $10,000 or less between individuals are exempt from these imputed interest rules as long as the borrowed money is not used to buy income-producing assets, but a down payment loan is almost always well above that threshold.

To keep a family loan a loan, charge at least the current AFR for the loan’s term, use a written promissory note, and actually make the payments on schedule. The AFR is published monthly.¹⁰ Without those pieces, the IRS can recharacterize the whole thing as a gift.

The lender cares about this distinction too. A loan counts as debt on your application; a gift does not. Calling a loan a gift to get better mortgage terms is fraud. Pick the label honestly at the start and paper it accordingly.

State Gift Tax

Most states do not impose a separate gift tax, so a down payment gift that is federally clean is almost always state-clean as well. A few states run unified gift and estate tax systems where large lifetime gifts can reduce the state exemption at death; a donor in one of those states making sizable gifts should get local advice. Real estate transfer taxes and recording fees at closing are a separate matter and are not a tax on the gifted funds.
