Diedrich v. Commissioner

Background

Two donors gave large blocks of stock to their children on the condition that the children pay the resulting federal and state gift taxes. In Diedrich, the donors’ basis in the stock was $51,073 and the donees paid $62,992 in gift taxes. In Grant, Mrs. Grant’s basis was $8,742.60 and the donee paid $232,620.09. The Tax Court sided with the taxpayers, but the Eighth Circuit reversed and the Supreme Court granted review to resolve a split among appeals courts.

Reasoning

The central question was whether a donor gets taxable income when a donee discharges the donor’s legal gift-tax obligation. The Court relied on prior decisions holding that relief from a legal obligation can be economic gain. Because the gift tax liability is legally the donor’s, a donee’s promise to pay it leaves the donor in a better economic position. The Court treated these transfers as part sale and part gift: the part that discharges the donor’s tax obligation is like consideration received, and the donor realizes income to the extent the donee’s payment of gift tax exceeds the donor’s adjusted basis.

Real world impact

The ruling means donors who make conditional “net” gifts may have to report capital gain or other taxable income when the tax paid by the donee exceeds the donor’s basis. The opinion applied to the cases before the Court (including the specific dollar increases found by the Commissioner) and noted that gift-tax valuation rules remain unchanged; Congress could change the income tax treatment if it wishes.

Dissents or concurrances

Justice Rehnquist dissented, arguing the Court wrongly transformed a gift into a partial sale and that Congress’s gift-tax statutes show no clear intent to treat such agreements as income events.
