GSAR Case 2026-G501, published 22 September 2026, would relocate Federal Supply Schedule ordering procedures from FAR subpart 8.4 to a new GSAR subpart 538.71, reorganize them by dollar threshold, and move order-level materials rules out of the contract clause. Comments close 22 October 2026.

A Cost Accounting Standards Board final rule published 1 September 2026 raises the basic CAS applicability threshold from $2.5 million to $35 million, doubles the full-coverage and Disclosure Statement threshold to $100 million, and sets how CAS exemptions apply to indefinite delivery contracts.

The provisions deferred until January 2026 are live. A disqualifying recertification can now cost a firm its eligibility for set-aside orders and option exercises under a multiple-award contract.
