Summary

Background

Asphalt Products Co. (APC) makes emulsified asphalt and kept its books on a cash basis. In 1974 APC had unusually large year-end inventories and accounts receivable and claimed a small deduction for transporting two trucks. The IRS adjusted APC's return, required accrual accounting for 1974, disallowed the truck deduction as a personal expense, and assessed a large tax deficiency and a 5% negligence penalty under 26 U.S.C. § 6653(a)(1).

Reasoning

The central question was whether the 5% negligence penalty applies to the entire tax underpayment or only to the portion caused by negligence. The Court read the statute literally and held that if any part of an underpayment is due to negligence, the penalty is 5% of the whole underpayment. The Court therefore reversed the Sixth Circuit and rejected the view that the penalty should be limited to the negligent portion. The Court accepted, without endorsing, the Commissioner’s finding that APC had been negligent in claiming the truck deduction, and denied APC’s separate petition on the accounting method.

Real world impact

The decision lets the IRS apply the 5% negligence penalty to an entire shortfall whenever any negligent item contributed to it, increasing penalty exposure for businesses and taxpayers with mixed causes for underpayments. The opinion notes a government interest in deterring negligent tax preparation. Because the Court acted summarily, some Justices pointed out that Congress’ later work on the 1986 Tax Reform Act may affect how the rule applies to post-1986 tax years.

Dissents or concurrances

Justices Marshall and Blackmun argued against the Court’s summary reversal, saying full briefing and plenary review were appropriate; Marshall also noted congressional materials that disapproved the Court of Appeals’ approach for cases under the 1986 Act.
