Decision: United States v. Dalm, 494 U.S. 596 (1990).

Dalm settled an income-tax dispute, then tried to recover an earlier gift-tax payment on the same transfer. Her problem was not merely showing inconsistent tax treatment: The refund claim for the earlier tax was already years late. The Supreme Court held that equitable recoupment could not give the district court jurisdiction over that separate suit. Dalm, 494 U.S. at 598–602.

The same payments generated gift and income tax disputes

The decedent’s brother paid Dalm $180,000 in 1976 and $133,813 in 1977, separate from her court-approved estate-administration fees. A gift-tax return was filed for the 1976 transfer, and Dalm paid that tax. The IRS later treated both payments as additional compensation. After two days of Tax Court trial, the parties settled the income-tax dispute. Whether the settlement already accounted for the gift tax was disputed; the Supreme Court did not resolve that issue because jurisdiction failed first. Dalm, 494 U.S. at 598–601 & n.2.

The administrative claim was late

Dalm filed her gift-tax refund claim in November 1984, although the opinion identifies December 1979 as the deadline. She argued that payment should count from the later determination of inconsistent income-tax treatment. The Court rejected that approach: Discovering the alleged error later did not restart the payment date. This matters when a second audit exposes a problem with an old tax payment; the new dispute does not automatically reset the old refund clock. Dalm, 494 U.S. at 600, 602, 609–610 n.7.

Equitable recoupment is defensive

The Court distinguished recoupment within a timely case from using recoupment as the sole basis for a new refund suit. It also expressly left unanswered whether Dalm could have asserted recoupment in the Tax Court. That reservation prevents treating the decision as an instruction that her proposed Tax Court claim necessarily would have been available or successful. Dalm, 494 U.S. at 605–608, 611 n.8.

The refund judgment was reversed

On March 20, 1990, the Supreme Court reversed the Sixth Circuit. It identified statutory mitigation provisions but noted that Dalm’s action undisputedly fell outside them. The practical question is therefore specific: Is a timely proceeding still open, what relief can that forum grant, and does an actual statutory exception apply? Neither a later settlement nor a claim of unfair double taxation answers those questions by itself. Dalm, 494 U.S. at 610–611.

Key takeaways

• Calendar the section 6511 claim period independently of other tax disputes.
• File the administrative refund claim before suing.
• Raise same-transaction recoupment in a timely proceeding.
• Do not treat an equitable doctrine as a substitute for jurisdiction.
