How to Document a Gift for Tax Purposes: Form 709 and FMV Rules

To document a gift for tax purposes, a donor who transfers more than $19,000 to a single recipient in 2026 files IRS Form 709 and attaches records that pin down what was given, when, and what it was worth. The IRS looks for a specific description of the property, the fair market value on the date of transfer, the basis of the giver, and enough supporting detail that an examiner could evaluate the gift without asking for more. Doing this well matters even when no tax is due, because thorough documentation starts the statute of limitations and locks in the reported value.

When You Actually Need to Document a Gift

Federal law requires a gift tax return for any calendar year in which you make a gift above the annual exclusion or outside another exemption.¹ For 2026 the annual exclusion is $19,000 per recipient. Give any one person less than that in a year and you have no filing obligation and nothing to document for the IRS. Cross the line by even a dollar and the whole gift needs to be reported.

Several transfers are excluded regardless of amount and don’t require Form 709 documentation:

Tuition paid directly to an educational institution. The check has to go to the school, and only tuition itself qualifies — room, board, and books do not.²
Medical expenses paid directly to a provider or insurer. Reimbursing the patient does not qualify.²
Gifts between spouses who are both U.S. citizens. The marital deduction is unlimited. If the receiving spouse is not a citizen, the 2026 exclusion is $194,000.³
Gifts to qualifying charities.

For everything else above $19,000, reporting matters even though most donors will owe no tax. Amounts above the annual exclusion draw down the lifetime exemption, which is $15 million for 2026 under changes signed into law on July 4, 2025.⁴ Documentation is what protects the reported value against later revaluation.

The Core Details Every Gift Record Needs

Form 709 requires the full legal name, address, and Social Security Number or Taxpayer Identification Number for you and every recipient, along with your relationship to each one.⁵ Record the exact calendar date you gave up control of the asset. That is the valuation date the IRS will use.

Property descriptions must be specific enough that a stranger reading the return years later could identify what changed hands. The Form 709 instructions set out what each asset type requires:⁵

Real estate: the legal description from the deed, the street address if in a city, and a note of any improvements.
Stocks: number of shares, common or preferred, exact corporate name, the principal exchange (or the business office location if unlisted), and the CUSIP number.
Bonds: number of bonds, principal amount, obligor, maturity date, interest rate and payment dates, series number, exchange, and CUSIP.
Interests in closely held businesses: the entity’s Employer Identification Number.
Life insurance policies: the insurer’s name and the policy number.

For a gifted vehicle, include the VIN. For artwork or collectibles, keep a photograph and a physical description alongside the appraisal. The working test: if the IRS opens this return three years from now, can someone tell exactly what you gave?

Establishing Fair Market Value

The value you report is the fair market value on the gift date. Fair market value is the price the property would change hands for between a willing buyer and a willing seller, both reasonably informed and neither under pressure.⁶ How you prove that number depends on the asset.

Publicly Traded Securities

For stocks and bonds trading on an exchange, fair market value per share is the average of the highest and lowest quoted selling prices on the gift date.⁷ If nothing traded that day, use a weighted average of the nearest trading days before and after, weighted inversely by how many days each is from the gift date. Save or print the market data showing those quotes. That printout is your primary evidence.

Assets That Require a Qualified Appraisal

Non-cash assets without an active public market need a formal appraisal from a qualified professional. That covers real estate, fine art, jewelry, antiques, and interests in private businesses. A qualified appraiser must hold a recognized appraiser designation or have at least two years of experience valuing that specific type of property, must regularly prepare appraisals for compensation, and must follow the Uniform Standards of Professional Appraisal Practice.⁸ The fee cannot be a percentage of the appraised value.

The appraisal itself should spell out the methodology, the appraiser’s qualifications, comparable sales or other benchmarks, and the specific valuation date. Residential real estate appraisals for tax purposes typically run $300 to $1,200. Unique assets cost more. This is the wrong place to save money: the IRS imposes a 20% accuracy-related penalty when the reported value turns out to be 65% or less of the correct value, and a properly prepared appraisal is your main defense.⁹

Adequate Disclosure Is What Locks the Value In

This is the part of documentation that produces the real protection. If a gift is adequately disclosed on the return, the IRS generally has three years from the filing date to challenge the value. After that, the number is fixed for both gift and estate tax purposes. A gift that is not adequately disclosed, or is left off entirely, has no statute of limitations — the IRS can revalue it years later, often at estate settlement, when it’s too late to fight back with contemporaneous evidence.¹⁰

Adequate disclosure means the return itself carries enough information for the IRS to evaluate the gift without asking for more. That means the identity and relationship of donor and donee, a thorough description of the property, the valuation method or appraisal used, and a description of any consideration received in return.⁵ For gifts of interests in closely held entities, attach the underlying financial statements and the appraisal.

The stakes vary by asset. A $25,000 cash gift leaves nothing to argue about. A 15% interest in a family LLC, with valuation discounts and judgment calls baked into the number, is exactly the kind of gift the IRS can and does revisit. Thorough disclosure starts the three-year clock. Thin or missing information keeps the door open indefinitely.

Reporting the Gift on Form 709

Download the current version of Form 709 from the IRS website.¹¹ Schedule A is where the actual gift information goes. Part 1 covers gifts to individuals. Part 2 covers direct skips to someone two or more generations below you, such as a grandchild. For each gift, enter the recipient’s name and address, describe the property in enough detail to meet the adequate disclosure standard, and record the gift date, your adjusted basis, and the fair market value.¹²

The adjusted basis is what you would use to calculate income tax if you had sold the property instead: generally original cost plus improvements, minus depreciation.⁵ Reporting it accurately serves the IRS and, more practically, gives your recipient the number they will need if they ever sell.

Gift Splitting Between Spouses

Married donors can elect to treat each gift as if each spouse gave half, effectively doubling the annual exclusion to $38,000 per recipient in 2026. Both spouses must consent in Part 1, and the non-donor spouse must also file their own Form 709 for the year, even if they made no gifts of their own.¹² The election draws from both lifetime exemptions proportionally, so it’s worth a conversation with a tax professional before making it.

How Long to Keep the Records

The IRS generally has three years from filing to audit a gift tax return.¹³ That grows to six years if the return omits gifts worth more than 25% of the total gifts reported for the year.¹⁴ Undisclosed gifts have no statute of limitations at all.

In practice, keep gift tax records indefinitely. At your death, the executor will need the cumulative history of your lifetime taxable gifts to calculate estate tax. Without records, the IRS may fill in its own values. Your heirs will also need your basis figures to work out their own tax when they eventually sell. A fireproof safe or secure cloud folder costs far less than reconstructing decades of gift history.

Give the Recipient a Copy

When you give someone property, the recipient generally inherits your tax basis rather than getting a step-up to current market value.¹⁵ Stock you bought for $10,000 and gave away at $50,000 leaves the recipient with a $10,000 basis. When they sell, they pay capital gains on the $40,000 difference. Inherited property works the opposite way, with basis stepped up to fair market value at death.

One wrinkle: if fair market value on the gift date is lower than your basis, the recipient uses that lower value as their basis for calculating a loss. Both numbers matter to them. Give the recipient a copy of Form 709 and any supporting appraisals when you file. Donors routinely skip this step, and recipients discover the gap years later when they sell and cannot document what they owe.

A Gift Letter for a Mortgage Is a Separate Document

If the cash gift is going toward a home purchase, the recipient’s lender will want its own paperwork, and that paperwork does not substitute for Form 709. Fannie Mae guidelines require a signed gift letter stating the dollar amount, confirming no repayment is expected, and giving the donor’s name, address, phone number, and relationship to the borrower.¹⁶ Lenders also typically want a paper trail showing the withdrawal from the donor and the deposit to the borrower.

The lender is confirming that the money is a gift and not a hidden loan. The IRS is tracking the transfer against your lifetime exemption. If a gift above the annual exclusion is funding a home purchase, handle both.
