What Constitutes a Gift for Tax Purposes: IRS Rules and Form 709

For federal tax purposes, a gift is any transfer of money, property, or the right to use property where you don’t receive something of equal value in return. That is what constitutes a gift for tax purposes, and the IRS applies the definition whether or not you thought of the transfer as a gift in the everyday sense. What saves most people from ever paying gift tax is not the definition but two large carve-outs: a $19,000 annual exclusion per recipient in 2026, and a $15,000,000 lifetime exemption that absorbs anything above it.¹

The IRS Definition

Federal law imposes a tax on the transfer of property by gift during each calendar year.² A gift happens when you hand over money, property, or the use of property without receiving at least equal value back.³ Intent does not control the outcome. What matters is the value exchanged.

Selling something for less than it is worth counts. If you sell your child a car worth $30,000 for $5,000, the $25,000 difference is a gift. Letting a family member live in a rental property for free, forgiving a loan, or adding someone to a bank account can all create taxable gifts depending on the circumstances. One exception cuts the other way: transfers made in the ordinary course of business, at arm’s length, with no donative intent, are not treated as gifts even if the price turns out to be favorable.

The tax always falls on the donor, not the recipient. If you give your niece $50,000, you are the one responsible for reporting and paying any tax that comes due.⁴ The recipient generally owes nothing on the value received, though for property other than cash they take over your cost basis and will owe capital gains tax on any appreciation when they eventually sell.⁵

Transfers That Are Not Taxable Gifts

Several categories of transfers sit entirely outside the gift tax, no matter how large. They do not consume your annual exclusion or your lifetime exemption.

The Annual Exclusion

In 2026, you can give up to $19,000 to any number of recipients without filing a return or using any lifetime exemption.¹ The exclusion runs per recipient, per year. Give $19,000 each to five different people, and you have made $95,000 in tax-free gifts with no paperwork required.

The gift must be a “present interest,” meaning the recipient can use or benefit from it right away. Gifts of future interests, like a trust distribution the beneficiary cannot touch for years, do not qualify for the annual exclusion regardless of amount.⁶

Direct Payments for Tuition and Medical Bills

You can pay someone’s tuition or medical expenses in any amount, free of gift tax, as long as you pay the school or medical provider directly.⁶ This is where people trip up. Writing a check to your grandchild to “help with tuition” does not qualify. The payment must go straight to the educational institution or healthcare provider. Done correctly, these payments do not count toward the $19,000 annual exclusion at all, so you can pay $80,000 in tuition and still give that same person $19,000 in cash the same year. The tuition exclusion covers education and training costs but does not extend to room, board, or books.

Gifts to a Spouse

Gifts to a spouse who is a U.S. citizen qualify for an unlimited marital deduction, so you can transfer any amount to your spouse gift-tax-free.⁷ If your spouse is not a U.S. citizen, that unlimited deduction disappears. You get an enhanced annual exclusion of $194,000 for 2026, and anything above it is a taxable gift.⁸

Charitable and Political Gifts

Gifts to qualifying charities are deductible from your total taxable gifts for the year.⁹ Transfers to political organizations for their use are not treated as gifts at all and do not need to be reported on Form 709.¹⁰

Transfers People Don’t Realize Are Gifts

Several everyday transactions meet the IRS definition even though no one sat down intending to make a gift.

Below-Market Loans

Lending money to a family member at zero interest, or at a rate below the IRS’s Applicable Federal Rate, creates a deemed gift. The difference between the interest you should have charged and what you actually charged is a gift from you to the borrower. A safe harbor applies for loans of $10,000 or less between individuals, as long as the borrower doesn’t use the money to buy income-producing assets. For loans between $10,000 and $100,000, the deemed gift is capped at the borrower’s net investment income for the year. Above $100,000, the full interest differential is a taxable gift.¹¹

Forgiving a Debt

If you loaned someone $50,000 and later tell them not to worry about paying it back, you have made a $50,000 gift. The IRS treats any release of an obligation without receiving full value as a transfer by gift.¹² If you plan to forgive a loan gradually, forgiving $19,000 per year keeps each installment within the annual exclusion.

Bargain Sales

A sale for less than fair market value produces a gift equal to the shortfall. The classic case is the discounted family car or house, but it works the same way for any asset. Documenting the fair market value on the date of sale matters, because the gift portion is measured against it.

529 Plan Contributions

Contributions to a 529 education savings plan count as gifts to the beneficiary. A special rule lets you “front-load” up to five years of annual exclusions into a single contribution. In 2026, that means you can put up to $95,000 per beneficiary into a 529 in one year, or $190,000 if you split gifts with your spouse, and spread the gift across five years for gift tax purposes.¹³ You elect this treatment on Form 709. Any additional gifts to that same beneficiary during the five-year window stack on top and can push you past the annual exclusion.

How the IRS Values a Gift

Every gift is valued at its fair market value on the date of transfer. Fair market value is the price a willing buyer and a willing seller would agree on, with neither under pressure and both having reasonable knowledge of the facts.¹⁴ Cash is straightforward. Everything else takes work.

Publicly traded stocks and bonds are valued using the average of the highest and lowest selling prices on the date of the gift.¹⁰ If a stock’s high was $50 and its low was $46 on the transfer date, the gift value is $48 per share. Real estate, closely held business interests, and artwork typically require a professional appraisal. For high-value property, an appraisal is not optional as a practical matter; the IRS scrutinizes valuations that appear to minimize gift tax exposure, and an unsupported number on Form 709 invites an audit.

Reporting a Gift Does Not Mean Owing Tax

When a gift exceeds the $19,000 annual exclusion, the excess becomes a “taxable gift” that you must report on Form 709. Reporting is not the same as owing. Every person has a lifetime exemption that absorbs taxable gifts before any actual tax is due. For 2026, the lifetime exemption is $15,000,000, set by the One, Big, Beautiful Bill signed into law on July 4, 2025.¹

Suppose you give your daughter $119,000 in 2026. The first $19,000 is covered by the annual exclusion. The remaining $100,000 is a taxable gift you report on Form 709, but instead of paying tax you apply $100,000 of your lifetime exemption. Your remaining exemption drops from $15,000,000 to $14,900,000. The gift tax and estate tax share this single exemption, so what you use during your lifetime reduces what is available to shelter your estate at death.¹⁵

If you exhaust the entire $15,000,000 exemption during your lifetime, additional taxable gifts are taxed at a top rate of 40%.¹ Few people reach this point. Married couples can further stretch the annual exclusion by electing to split gifts, treating a gift from one spouse as coming half from each; the election requires the non-donor spouse’s written consent on the return.¹⁰

When You Must File Form 709

You must file Form 709 for any year in which you give more than $19,000 to any single recipient (other than your citizen spouse), make a gift of a future interest in any amount, or elect to split gifts with your spouse.¹⁰ Filing is required even when the lifetime exemption covers the entire amount and no tax is owed.

The return is due by April 15 of the year following the gift.¹⁶ An extension for your individual income tax return on Form 4868 automatically extends Form 709. If you want more time only for the gift tax return, file Form 8892 by April 15 for an automatic six-month extension.¹⁷ An extension to file is not an extension to pay; any gift tax owed is still due on April 15.

Why Filing Matters Even When No Tax Is Due

Once you file a properly completed Form 709, the IRS generally has three years from the filing date to audit the return and assess additional tax. After that window closes, the valuation is locked in. If you never file, or omit a gift from the return, there is no statute of limitations. The IRS can come back at any time to revalue the gift or assess tax on it.¹⁸

That is the practical reason to file even when the lifetime exemption more than covers the gift. Filing starts the clock on the IRS’s ability to challenge how you valued the property. Donors who skip filing on a large real estate gift because “no tax is owed anyway” can leave their estates open to a valuation fight decades later, when the appraiser and the contemporary records may be long gone.
