31 U.S.C. § 3902

(a) Under regulations prescribed under section 3903 of this title , the head of an agency acquiring property or service from a business concern, who does not pay the concern for each complete delivered item of property or service by the required payment date, shall pay an interest penalty to the concern on the amount of the payment due. The interest shall be computed at the rate of interest established by the Secretary of the Treasury, and published in the Federal Register, for interest payments under section 7109(a)(1) and (b) of title 41, which is in effect at the time the agency accrues the obligation to pay a late payment interest penalty. (b) The interest penalty shall be paid for the period beginning on the day after the required payment date and ending on the date on which payment is made. (c) (1) A business concern shall be entitled to an interest penalty of $1.00 or more which is owed such business concern under this section, and such penalty shall be paid without regard to whether the business concern has requested payment of such penalty. (2) Each payment subject to this chapter for which a late payment interest penalty is required to be paid shall be accompanied by a notice stating the amount of the interest penalty included in such payment and the rate by which, and period for which, such penalty was computed. (3) If a business concern— (A) is owed an interest penalty by an agency; (B) is not paid the interest penalty in a payment made to the business concern by the agency on or after the date on which the interest penalty becomes due; (C) is not paid the interest penalty by the agency within 10 days after the date on which such payment is made; and (D) makes a written demand, not later than 40 days after the date on which such payment is made, that the agency pay such a penalty, such business concern shall be entitled to an amount equal to the sum of the late payment interest penalty to which the contractor is entitled and an additional penalty equal to a percentage of such late payment interest penalty specified by regulation by the Director of the Office of Management and Budget, subject to such maximum as may be specified in such regulations. (d) The temporary unavailability of funds to make a timely payment due for property or services does not relieve the head of an agency from the obligation to pay interest penalties under this section. (e) An amount of an interest penalty unpaid after any 30-day period shall be added to the principal amount of the debt, and a penalty accrues thereafter on the added amount. (f) This section does not authorize the appropriation of additional amounts to pay an interest penalty. The head of an agency shall pay a penalty under this section out of amounts made available to carry out the program for which the penalty is incurred. (g) A recipient of a grant from the head of an agency may provide in a contract for the acquisition of property or service from a business concern that, consistent with the usual business practices of the recipient and applicable State and local law, the recipient will pay an interest penalty on amounts overdue under the contract under conditions agreed to by the recipient and the concern. The recipient may not pay the penalty from amounts received from an agency. Amounts expended for the penalty may not be counted toward a matching requirement applicable to the grant. An obligation to pay the penalty is not an obligation of the United States Government. (h) (1) This section shall apply to contracts for the procurement of property or services entered into pursuant to section 4(h) of the Act of June 29, 1948 ( 15 U.S.C. 714b(h) ). (2) (A) In the case of a payment to which producers on a farm are entitled under the terms of an agreement entered into under the Agricultural Act of 1949 ( 7 U.S.C. 1421 et seq.), an interest penalty shall be paid to the producers if the payment has not been made by the required payment or loan closing date. The interest penalty shall be paid— (i) on the amount of payment or loan due; and (ii) for the period beginning on the first day beginning after the required payment or loan closing date and ending on the date the amount is paid or loaned. (B) As used in this subsection, the “required payment or loan closing date” means— (i) for a purchase agreement, the 30th day after delivery of the warehouse receipt for the commodity subject to the purchase agreement; (ii) for a loan agreement, the 30th day beginning after the date of receipt of an application with all requisite documentation and signatures, unless the applicant requests that the disbursement be deferred; (iii) for refund of amounts received greater than the amount required to repay a commodity loan, the first business day after the Commodity Credit Corporation receives payment for such loan; (iv) for land diversion payments (other than advance payments), the 30th day beginning after the date of completion of the production adjustment contract by the producer; (v) for an advance land diversion payment, 30 days after the date the Commodity Credit Corporation executes the contract with the producer; (vi) for a deficiency payment (other than advance payments) based upon a 12-month or 5-month period, 91 days after the end of such period; or (vii) for an advance deficiency payment, 30 days after the date the Commodity Credit Corporation executes the contract with the producer. (3) Payment of the interest penalty under this subsection shall be made out of funds available under section 8 of the Act of June 29, 1948 ( 15 U.S.C. 714f ). (4) Section 3907 of this title shall not apply to interest penalty payments made under this subsection.
