437.52—Collection of amounts due.

(a) Any funds paid to a grantee in excess of the amount to which the grantee is finally determined to be entitled under the terms of the award constitute a debt to the Federal Government. If not paid within a reasonable period after demand, SSA may reduce the debt by:
(1) Making an administrative offset against other requests for reimbursements,
(2) Withholding advance payments otherwise due to the grantee, or
(3) Other action permitted by law.
(b) Except where otherwise provided by statutes or regulations, SSA will charge interest on an overdue debt in accordance with the Federal Claims Collection Standards (4 CFR chapter II). Litigation or the filing of any form of appeal does not extend the date from which interest is computed.
