§1503 Contract price adjustment

Title 41 › Subtitle Subtitle I— - Federal Procurement Policy › Chapter CHAPTER 15— - COST ACCOUNTING STANDARDS › § 1503

Last updated Apr 6, 2026|Official source

Summary

If the federal government and a contractor or subcontractor cannot agree on a change in contract price or on whether the contractor followed cost-accounting rules, the disagreement becomes a formal federal dispute. When the government makes a price adjustment to avoid paying extra costs, it may only recover the total increased costs as defined by the Cost Accounting Standards Board. The government can recover more only if the contractor changed its accounting methods, knew or should have known about the change during price talks, and failed to tell the government. Recovered costs must exclude any fixed-price work (where the price does not change) or any part that cannot be reset based on actual costs. For work that is not fixed-price, recovery in a fiscal year cannot be more than the net increased costs actually paid that year for all accounting changes. Interest is charged at the annual rate set in the Internal Revenue Code and runs from when the extra payments were made until the government is fully repaid.

(a)If the Federal Government and a contractor or subcontractor fail to agree on a contract price adjustment, including whether the contractor or subcontractor has complied with the applicable cost accounting standards, the disagreement will constitute a dispute under chapter 71 of this title.
(b)A contract price adjustment undertaken under section 1502(f)(2) of this title shall be made, where applicable, on relevant contracts that are subject to the cost accounting standards so as to protect the Federal Government from payment, in the aggregate, of increased costs, as defined by the Cost Accounting Standards Board and in accordance with the following requirements:
(1)The Federal Government may not recover costs greater than the aggregate increased cost to the Federal Government, as defined by the Board, on the relevant contracts subject to the price adjustment unless the contractor or subcontractor made a change in its cost accounting practices of which the contractor or subcontractor was aware or should have been aware at the time of the price negotiation and which contractor or subcontractor failed to disclose to the Federal Government.
(2)For such changes in cost accounting practices—
(A)costs recovered by the Federal Government shall exclude any contract or subcontract (or any portion of such contract or subcontract) that is firm, fixed-price, or that is not price-redeterminable based on costs; and
(B)for a fiscal year, for any contract or subcontract (or any portion of such contract or subcontract) that is not a firm, fixed-price contract or subcontract the costs recovered by the Federal Government shall not exceed the net increased costs, if any, paid to the contractor or subcontractor for all changes in cost accounting practices implemented within the same fiscal year.
(c)The interest rate applicable to a contract price adjustment is the annual rate of interest established under section 6621 of the Internal Revenue Code of 1986 (26 U.S.C. 6621) for the period. Interest accrues from the time payments of the increased costs were made to the contractor or subcontractor to the time the Federal Government receives full compensation for the price adjustment.
