United States v. Brockamp: Tax-Refund Deadlines Were Not Equitably Tolled

By Aneeta Mishra and Timothy Chan

Published April 23, 2026

Brockamp reads the tax-refund limitation scheme as too detailed and emphatic to contain a general judge-made equitable-tolling exception.

Two taxpayers sought late refunds

Each taxpayer paid money not owed and filed an administrative refund claim after the statutory period. They invoked mental disability—senility in one matter and alcoholism in the other—as an equitable reason to excuse the delay.

Section 6511 uses unusually detailed limits

The statute states filing deadlines in several alternative forms, repeats them, and couples them with amount limitations. The Court found that technical structure inconsistent with an implied, open-ended equitable exception.

Tax administration reinforced the text

Congress wrote section 6511 to govern very large numbers of claims. Case-by-case tolling based on factual disability inquiries could create administrative complexity that the statute did not authorize courts to introduce.

Disposition

The Court reversed the Ninth Circuit judgments and held that the nonstatutory equitable tolling doctrine did not apply. Later statutory amendments must be examined separately for periods and circumstances they expressly cover.

Key takeaways

• Calendar both the refund-claim filing period and lookback limit.
• Do not assume ordinary equitable tolling applies to section 6511.
• Identify any express statutory suspension provision.
• File protective administrative claims before uncertainty is resolved.
