COST ACCOUNTING UPDATE · VERIFIED SEPTEMBER 30, 2026

CAS Board issues two final rules: what federal contractors should verify.

Acquisition.gov reported that the Cost Accounting Standards Board issued two final rules on September 1, 2026: one concerning CAS 407 and generally accepted accounting principles, and another concerning monetary thresholds and other CAS program requirements.

Federal contractors with Cost Accounting Standards exposure have two September rulemakings to add to their review list. Acquisition.gov announced on September 2 that the CAS Board had issued two final rules the previous day and linked directly to the corresponding Federal Register publications.

The practical point: do not assume that every federal bidder is affected in the same way. CAS applicability depends on the contract, award value, contractor status, exemptions and other facts. The right next step is to identify whether either rule touches your current accounting obligations or upcoming procurements and then read the official text.

What did the CAS Board publish?

According to Acquisition.gov, the first final rule is titled “Conformance of Cost Accounting Standards to Generally Accepted Accounting Principles for CAS 407, Use of Standard Costs for Direct Material and Direct Labor.” The second is titled “Increase of Monetary Thresholds and Other Matters Related to Cost Accounting Standards Program Requirements.”

The official announcement also points practitioners to supporting materials associated with recent CAS rulemaking. That is useful because the headline of a final rule is not enough to determine its impact on a specific contractor, accounting system or solicitation.

What should contractors review?

1. Contract and solicitation applicability

Start with the procurement documents and your existing contract terms. Check whether CAS coverage is referenced, whether an exemption applies, and whether the rule’s effective and applicability provisions reach the work you are evaluating.

2. Accounting policy documentation

If your organization uses standard costs for direct material or direct labor, the CAS 407 rule is a reason to have the responsible accounting or compliance team review the official final text against current written practices. Avoid changing policy based only on a summary.

3. Threshold-dependent procedures

For the rule addressing monetary thresholds and related program requirements, identify internal procedures that depend on award or contract value. Threshold changes can matter to screening, disclosure, review and administration processes, but the exact effect must come from the rule itself.

4. Proposal assumptions

When pricing a federal proposal, document which accounting requirements and assumptions were used. If a rule changes during a long capture or proposal cycle, the team should be able to see what was assumed when pricing, what changed, and whether the solicitation has incorporated that change.

Why this belongs in a bid-readiness workflow

Cost accounting requirements sit downstream from the initial “does this opportunity fit?” question, but they can become material quickly on larger or more complex procurements. A disciplined opportunity review therefore checks not only service match and deadline but also contract type, clauses, representations, certifications, accounting requirements and any specialist review needed before a price is committed.

For teams building that review process, GovBidFit’s contract readiness checklist and proposal compliance matrix can help organize the internal questions. They do not replace an accountant, counsel, contracting officer or the official solicitation.
