Gov Proposes Matching Cost Rules to Standard Accounting
Published Date: 3/20/2026
Proposed Rule
Summary
The government wants to update rules about how companies use standard costs for materials and labor to match regular accounting rules (GAAP). This affects businesses that work with federal contracts and could change how they report costs. Comments on these changes are open until April 20, 2026, so get ready to share your thoughts!
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Large Cut to CAS 407 Rules
The Board proposes to eliminate 12 of the 16 requirements in CAS 407 and remove over 2,000 words of regulatory text, relying on contractors' GAAP disclosures instead. This is meant to reduce duplicative compliance for government contractors and outside auditors if the change is finalized.
Easier Entry for Non‑Traditional Contractors
The Board expects the proposal to reduce barriers to entry for non-traditional contractors and new mid-size entities, which it says should increase competition in federal contracting. The NPRM cites the Senate Armed Services Committee report urging CAS–GAAP conformance to level the playing field.
Some Production‑Unit Rules Stay in Place
Although most CAS 407 content would be removed, the Board proposes to retain limited requirements about accounting for standard costs and variances at the production‑unit level and move them into CAS 418 (e.g., the production unit definition and rules on allocation of variances). Contractors must still account for variances (allocated at least annually) or treat immaterial variances as indirect costs as specified in the proposed 9904.418(h).
Small Businesses Remain Exempt from CAS
The NPRM states that CAS Board rules do not impact small entities because contracts and subcontracts with small business concerns are exempt from all CAS requirements. That exemption continues to shield small businesses from these CAS changes.
