Title 31 › Subtitle SUBTITLE III— FINANCIAL MANAGEMENT › Chapter 37— CLAIMS › Subchapter II— CLAIMS OF THE UNITED STATES GOVERNMENT › § 3717
Agencies must charge interest on money people owe the U.S. at a yearly rate equal to the average investment rate for Treasury tax and loan accounts for the 12‑month period ending September 30, rounded to the nearest whole percent. The Treasury Secretary must publish that rate before November 1, and it starts on the first day of the next calendar quarter. The Secretary can change the rate for a quarter if the new 12‑month average (ending the last quarter) differs from the published rate by 2 percentage points or more. Interest begins on the date the agency mails the bill — with special start-date rules tied to notices around October 24–25, 1982 — and the rate that applies when interest starts stays the same for the whole debt. No interest is added if the debt is paid within 30 days of the start date; an agency head can extend that 30 days. Agency heads must also add a processing charge and may add a penalty up to 6 percent per year for amounts more than 90 days past due. Interest is not charged on those added fees. The rules do not apply if another law, rule, or contract forbids or fixes interest or charges, or to contracts made before October 25, 1982 that were in effect then. Agencies may write rules, following standards set with the Attorney General, Treasury, and Comptroller General, to waive interest and charges. Instead of interest and penalties, an agency can raise the debt by a yearly cost‑of‑living adjustment. Cost‑of‑living adjustment = percent change in the Consumer Price Index for June; administrative claim = debt not from government loans, such as fines, penalties, and overpayments.
