Do I Have to Worry About the Gift Tax If I Give My Son $75,000 Toward a Down Payment?

Unless you have already used most or all of your $15 million federal lifetime basic exclusion amount, a $75,000 gift generally will not trigger federal gift tax in 2026. Using the money for a down payment does not change the federal gift tax treatment. In fact, most families will never have to worry about either the gift tax or the estate tax thanks to gifting exemptions that are adjusted upward every year to account for inflation. In 2026, you can give up to $19,000 to each recipient without using any of your lifetime exclusion. If a gift exceeds that amount, the excess generally counts against your $15 million basic exclusion amount. As a result, a $75,000 gift will not produce federal gift tax for most households, although it can create a gift tax filing requirement.

What Is the Gift Tax?

The IRS may impose gift tax when someone transfers money or property without receiving full value in return. For example, if you sell someone a $500,000 house for $10, this would be considered a $499,990 gift. 

Gift and estate taxes are two related taxes within the unified federal transfer tax system. If you make the transfer while alive, it’s known as gift tax. If you make the transfer after death, it’s called the estate tax.  

Gift tax rates range from 18% to 40% of the taxable gift depending on the amount in question. The donor, not the recipient, pays this tax in their filings for the year in which they made the transfer. 

However, both the gift tax and estate tax only apply to very wealthy households. That’s because, throughout your life, the IRS allows you to give away a certain amount of money and assets free of any taxes. This is known as the lifetime exemption, and in 2026, the federal basic exclusion amount is $15 million per individual.

The IRS also allows you to gift up to $19,000 to each recipient in 2026 without using any of that lifetime amount. This is known as the annual exclusion. For example, say you have three adult children and you give each of them $25,000 in 2026. You won’t have to pay taxes on this money, but the three gifts will reduce your lifetime exemption by $18,000 since each one exceeded the annual exclusion by $6,000. If you give above this amount to a single person, you must report the excess gift on Form 709 when you file your taxes.

Keep in mind that everyone has both a lifetime exemption and annual exclusion limit, even married couples who file their taxes jointly. This means in 2026 each spouse has a $19,000 annual exclusion for gifts to each recipient and a $15 million basic exclusion amount. But if you need additional help with your gifting strategy, consider working with a financial advisor.

Applying the Gift Tax to a $75,000 Gift

The gift tax may apply regardless of the purpose or recipient. So, for example, giving an adult child money toward a down payment on a home would not change the taxable nature of the gift.

For a $75,000 gift made to one son in 2026, $19,000 can be covered by the annual exclusion. That leaves $56,000 to account for under the federal gift tax rules. For someone with enough of the $15 million basic exclusion amount still available, that $56,000 generally uses part of the remaining exclusion instead of generating an immediate gift tax bill.

To understand this further, let’s look at a few examples:

Scenario 1: Individual With No Giving

• Filing Status: Single
• Lifetime Exemption Used: $0
• Taxes Owed on $75,000 Gift: $0

First, picture yourself as a single filer. You have never given any gifts above the annual exclusion, so you have never used any of your lifetime exemption. A $75,000 gift to your son would exceed your annual exclusion by $56,000, reducing your lifetime exemption by the same amount. Starting with the full $15 million basic exclusion amount for 2026, subtracting $56,000 would leave $14.944 million available, assuming no other transfers affect the calculation.

Scenario 2: Individual With High Giving

• Filing Status: Single
• Lifetime Exemption Used: $14.99 million
• Taxes Owed on $75,000 Gift: Varies

Now, imagine that you’re an individual filer with considerable wealth. You’ve given away enough money to various individuals during your lifetime and have used up all but $10,000 of your lifetime exemption.

The $75,000 transfer would first be reduced by the $19,000 annual exclusion, leaving a $56,000 taxable gift. If only $10,000 of the donor’s applicable exclusion remained available, the gift would use that remaining amount and leave $46,000 exposed to federal gift tax. The actual tax calculation depends on the donor’s cumulative taxable gifts and available credit, so the tax should not be determined simply by applying one marginal rate to the $46,000.

Scenario 3: Gift Splitting Among Spouses

• Filing Status: Married, Joint
• Lifetime Exemption Used: $0
• Taxes Owed on $75,000 Gift: $0

Now, imagine that you’re married, you file your taxes jointly with your spouse and your spouse consents to gift splitting under the gift-tax rules. Neither spouse has given gifts above the annual exclusion in any year, nor have you given your son any money this year. 

As a result, you could engage in what’s called “gift splitting.” This means that you and your spouse each claim a portion of the gift. Because each spouse has a $19,000 annual exclusion in 2026, the couple can potentially cover $38,000 of the transfer with their annual exclusions. The other $37,000 would then be taken into account under the lifetime gift tax rules. If the $75,000 gift is treated equally between the spouses, that would leave $18,500 above each spouse’s $19,000 annual exclusion. Gift splitting generally requires the spouses to consent to the treatment on Form 709.

If you’re thinking about giving away a large sum of money, it may be wise to speak with a financial advisor before you do to go over any tax implications – good or bad – of the gift.

When Form 709 Comes Into the Picture

Writing a $75,000 check and owing gift tax are two separate issues. For a single donor making the entire transfer to one son in 2026, $56,000 remains after subtracting the $19,000 annual exclusion. Even if the donor has enough lifetime exclusion available to keep the transfer from producing a federal gift tax bill, the gift generally still needs to be disclosed on Form 709.

That filing also creates a record of how much of the donor’s available exclusion has been used. Suppose the donor begins 2026 without any prior taxable gifts. After accounting for the annual exclusion, the $56,000 associated with this gift would be reflected in the donor’s gift tax history. This distinction matters because reporting a gift does not, by itself, mean that tax must be paid with the return.

For a gift completed in 2026, the federal gift tax return is generally due April 15, 2027. Other gifts, gift splitting or more complicated transfers can affect the filing, so a donor making a large transfer may want to review the return requirements before the deadline.

Gifting a Down Payment

There are no special gift tax rules around a down payment but the mortgage system can make this process a little more complicated. Banks use down payments to assess whether a borrower can afford to pay the loan, so they add extra steps when the money comes from a third party. The IRS and the federal government also pay closer attention to third-party down payments, as this is a popular form of fraud and money laundering. 

Broadly speaking, there are three main considerations here:

Gift Letters

Lenders will carefully review the finances of any borrower, so they will see if a third party transferred them the down payment money. Make sure to provide a letter or other documentation stating that this is a gift, not a loan or other form of ongoing interest. Also, state your relationship with the recipient to prevent suspicion of money laundering. Lenders may restrict eligible gift donors depending on the mortgage program.

Season the Funds

Down payment gifts are typically only allowed from relatives. If an outside third-party makes the gift, money should be transferred at least 60 days before the borrower applies for their loan. This is called “seasoning the funds.” Lenders frequently require it as a way of preventing money laundering, as last-minute transfers may indicate fraud.

Direct Payment

Typically it is better to give the borrower money for a down payment directly. However, in some cases, the down payment can be made directly to the lender. This is often done via a wire transfer, with the donor gifting funds directly to the settlement agent without becoming a borrower. A signed gift letter and proof of funds may also be necessary. ¹

Giving someone a down payment will not affect their title or interest in the house. So long as you make the transfer with no requirements or strings attached, the money is theirs and the title will be clear. 

Bottom Line

Only very large gifts trigger federal gift tax. In 2026, the annual exclusion remains $19,000 for each recipient, and the federal basic exclusion amount is $15 million per individual. A single donor who gives a son $75,000 would generally have $56,000 remaining after the annual exclusion. Provided sufficient lifetime exclusion is available, that amount can use part of the donor’s exclusion rather than result in an immediate federal gift tax payment, although Form 709 generally must be filed.
