Title 31 › Subtitle SUBTITLE III— - FINANCIAL MANAGEMENT › Chapter CHAPTER 37— - CLAIMS › Subchapter SUBCHAPTER II— - CLAIMS OF THE UNITED STATES GOVERNMENT › § 3717
Federal agencies must charge interest on unpaid government debts at a yearly rate equal to the average return on Treasury tax-and-loan accounts for the 12 months 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 quarterly rate if the new 12‑month average for the prior quarter is at least 2 percentage points higher or lower than the published rate. Interest starts on the date a notice of the amount due is mailed (special rules apply for notices around October 24–25, 1982). The interest rate in effect when interest starts stays the same for the whole debt. No interest is charged if the debt is paid within 30 days after interest starts (an agency head can extend this). Agencies must add a processing charge and may add a penalty up to 6 percent per year for amounts over 90 days past due. Interest does not add interest to those charges. The rule does not apply if another law, rule, loan deal, or contract forbids or fixes interest, or to contracts made before October 25, 1982 that were already in effect. Agencies can set rules to waive interest and charges under standards from the Attorney General, Treasury, and Comptroller General. Instead of interest and penalties, an agency may raise the debt once a year by a cost-of-living adjustment. Cost-of-living adjustment: percentage change in the Consumer Price Index for June. Administrative claim: debts not from direct government loans, loan guarantees, or insurance (includes fines, penalties, and overpayments).
