The FY 2026 NDAA changed how fixed price contracts are treated in Cost Accounting Standards (CAS) cost impacts, but timing remains critical. Government contractors with CAS covered awards issued before implementation may still face current clause requirements, making award dates and clause language important compliance considerations.

In June 2023, the Armed Services Board of Contract Appeals (ASBCA) denied Honeywell's motion to dismiss a $151 million claim alleging improper G&A allocation treatment under CAS 410. The Board affirmed that interdivisional cost transfers must be included in a total cost input base, contradicting Honeywell's position. Government contractors should review whether their G&A allocation bases are consistent with this ruling.

The Cost Accounting Standards (CAS) Board has been working to eliminate several cost accounting standards and replace them with reliance on GAAP. As of April 2026, five standards are under proposed elimination, including a new March 2026 NPRM for CAS 407. Contractors should be aware that removing these standards does not eliminate cost accounting or consistency obligations.

On March 20, 2026, the CAS Board issued a Notice of Proposed Rulemaking proposing significant increases to the CAS thresholds and changes to exemption determinations for indefinite-delivery contracts. Most changes reflect requirements in Section 1806 of the 2026 NDAA and are broadly favorable to contractors, though key concerns remain about the treatment of single-award indefinite-delivery contracts.

Section 1826 of the FY 2026 National Defense Authorization Act shifts DoD treatment of nontraditional defense contractors from discretionary to mandatory exemptions from key cost and business system requirements.

In reference to the now outdated terminology “Multiple Personality Disorders” (now “DID” or Dissociative Identity Disorder), my focus is on two Government actions, the 2026 NDAA (National Defense Authorization Act) and the very recent EO (Executive Order), “Prioritizing the Warfighter in Defense Contracting.” Before getting into the substance of this blog, just to note that one can only hope that the proposed/legislated changes to improve the efficiencies and effectiveness of the procurement process (for the Department of War and more broadly the US Government) will actually succeed and not be just one more set of idealized and unfulfilled political promises.

Recent statutory changes under the FY 2026 National Defense Authorization Act revise the applicability thresholds for the Cost Accounting Standards and limit certain post-award contract price adjustments.

How much do you know about DCAA and its oversight of your incurred cost proposals (ICP) and indirect cost rates? Would it help to understand what is done and why? Knowing what initiates a DCAA audit of an incurred cost proposal and maintaining a good system of internal controls can potentially keep you from audit.
