The Dual-Basis Rule for Property Received as a Gift

A recipient usually does not receive a fresh fair-market-value basis merely because property changed hands as a gift. The starting basis generally carries over from the donor. A special dual-basis rule applies when the property’s value had fallen below the donor’s adjusted basis by the time of the gift.

Use one basis for gain and another for loss

Assume the donor’s adjusted basis is $10,000 and the property’s fair market value when gifted is $8,000. If the recipient later sells for $12,000, use the donor’s $10,000 basis to calculate a $2,000 gain. If the sale price is $7,000, use the $8,000 gift-date fair market value to calculate a $1,000 loss. If the sale price falls between $8,000 and $10,000, using the gain basis would produce a loss while using the loss basis would produce a gain; the result is neither gain nor loss.

Adjust basis after the gift

The donor basis and gift-date value may need adjustments for later improvements, depreciation, casualty events, or other basis changes. Certain gift tax paid may increase basis under a statutory formula. The recipient needs the donor’s adjusted basis and the fair market value on the transfer date, so transfer records and valuation documents matter.

Do not confuse gift and inherited property

Gifted property and inherited property generally follow different basis frameworks. Inherited property often has a basis tied to fair market value at death, subject to exceptions; a gift commonly carries over the donor’s basis, with the dual-basis rule protecting the loss calculation when value declined before the transfer. The transfer date and legal character of the transfer therefore matter.

Exam method

1. Find donor adjusted basis immediately before the gift.
2. Find fair market value on the gift date.
3. If FMV is below donor basis, use donor basis for gain and FMV for loss.
4. Compare sale proceeds with both bases; if between them, recognize neither gain nor loss.
5. Adjust each basis for later capital improvements and other required events.

Work the three-price-zone calculation

First record the donor’s adjusted basis immediately before the gift and the property’s fair market value on the gift date. If fair market value is at least the donor’s basis, the recipient generally uses carryover basis for gain or loss, subject to adjustments such as gift tax. If fair market value is below basis, the recipient uses donor basis to calculate gain and gift-date fair market value to calculate loss.

When the sale price falls between the two figures in a loss-basis gift, neither basis produces a recognized gain or loss: using donor basis gives a loss, while using gift-date fair market value gives a gain. This middle zone prevents the recipient from claiming a loss on the donor’s built-in decline or recognizing a gain that arose only from that gap.

Example: a parent gives shares with adjusted basis of $10,000 when their fair market value is $7,000. A sale for $12,000 generally produces a $2,000 gain using carryover basis. A sale for $6,000 generally produces a $1,000 loss using gift-date value. A sale for $8,500 falls between those amounts and produces neither gain nor loss under the dual-basis rule.

The basis can change after the gift through stock splits, return of capital, capital improvements, depreciation, or other adjustments. Keep the donor’s records and the date-of-gift valuation. A recipient who cannot establish basis may have difficulty substantiating the tax result.

Gifted and inherited property are different. Inherited assets generally use a date-of-death or alternate-valuation basis under the applicable rules, while gifted property generally carries the donor’s basis. A gift made shortly before death can also trigger special anti-abuse provisions. Do not apply a step-up assumption to a lifetime gift.

For tax reporting, use the correct basis for the sale price zone and retain documentation. If property is converted to business or rental use, depreciation basis and later disposition rules can require separate calculations.

Key takeaway

When gifted property fell in value before the gift, there can be a gain basis and a separate loss basis. Use the right basis for the direction of the sale result.
