The fixed-price contracting mandate that reshaped federal acquisition this spring reached its first hard compliance date on July 15, 2026. Under class-deviation guidance the FAR Council issued to implement Executive Order 14402, "Promoting Efficiency, Accountability, and Performance in Federal Contracting," agencies now must secure written approval before releasing any solicitation that relies on a contract type other than fixed-price. The deadline also introduced the detail contracting officers had been waiting for: a four-tier table of approval thresholds that sets a far higher bar at the Pentagon than at civilian agencies.
Background
President Trump signed EO 14402 on April 30, 2026, establishing fixed-price with performance-based considerations as the "default and preferred" method of procurement across the government. The order pushed acquisition officials away from cost-reimbursement, time-and-materials, and labor-hour arrangements that shift performance risk onto the taxpayer, and it directed agencies to review their 10 largest non-fixed-price contracts by dollar value within 90 days, a separate deadline that falls on July 29, 2026.
The order left the operational mechanics to the FAR Council, which folded them into the broader FAR overhaul already underway. On July 1, 2026, the council posted updated class-deviation text for FAR Part 16 so agencies could stand up compliant deviations before the July 15 trigger. That guidance converted the executive order's policy language into concrete procedure: who must sign off, at what dollar level, and by when. Firms that watched the April announcement pass with little practical effect are now dealing with a rule that bites at the solicitation stage. The overhaul has been rewriting swaths of the Federal Acquisition Regulation piece by piece, and the Part 16 contract-type provisions rank among the changes most likely to touch a bidder's day-to-day pricing decisions rather than sitting in a compliance binder.
Key Details
As of July 15, 2026, a contracting officer who wants to use a non-fixed-price, or "covered," contract type must obtain an approved justification before the solicitation goes out. The requirement reaches three categories of work: new solicitations issued on or after July 15; solicitations issued before that date where no award has yet been made; and existing contracts or orders with 18 or more months of remaining performance, options included. That last category is the one that pulls active awards into the regime rather than leaving them untouched until recompete. The guidance carves out exceptions for emergency response, disaster relief, contingency operations, and research and development for major system acquisitions.
The freshest piece of the guidance is the tiered approval structure. Non-fixed-price awards above set dollar thresholds now require agency-head approval, and the ceilings vary sharply by agency: the Department of Defense at $100 million, NASA at $35 million, the Department of Homeland Security at $25 million, and all other agencies at $10 million. The tiered table gives the Pentagon and the two large civilian buyers substantially more room before a covered award must climb to the secretary's desk. Below each threshold, a covered contract type still demands a written justification from the contracting officer, but the sign-off stays at a lower level. Even at the top tier, the agency head may delegate approval only to the chief acquisition officer or another non-career Senior Executive Service official.
The guidance also builds in a grandfather window. Justifications for previously awarded contracts and for pre-July 15 solicitations that have not yet resulted in an award must receive agency-head approval no later than July 15, 2027. That gives agencies a full year to paper the existing base of covered work without forcing an immediate scramble across every open file. The two-date structure, an immediate gate on new solicitations paired with a one-year runway on the legacy portfolio, is what separates this compliance moment from the April announcement.
What It Means for Contractors
Contractors that build their businesses around cost-reimbursement and time-and-materials work face the sharpest adjustment. Research-heavy programs, early-stage development efforts, and services contracts with hard-to-scope requirements have long leaned on flexible contract types precisely because fixed-price arrangements load performance risk onto the vendor. Under the new regime, a program office that wants to keep a covered type must now justify it in writing and, above the applicable threshold, route it to the agency head. Every added layer of approval is a chance for the answer to come back "make it fixed-price." The practical effect is to raise the internal cost of choosing anything other than a firm fixed price, and that cost lands hardest on programs where the government itself cannot yet describe the finished deliverable with precision.
The tiered thresholds change the calculus depending on which agency a firm sells to. A defense contractor pursuing a $60 million development effort sits comfortably below the $100 million DOD ceiling, so a covered type there clears at a lower level. The same dollar value at a civilian agency other than NASA or DHS blows past the $10 million bar and lands on the agency head's desk. Companies that sell across multiple agencies will find the path of least resistance runs through whichever customer carries the higher threshold, and that the smaller civilian agencies now steer hardest toward fixed-price for anything of consequence.
For work already under contract, the 18-month remaining-performance test is the line to watch. Long-duration awards and heavily optioned vehicles fall inside the regime, and their justifications must be approved by July 15, 2027. Contractors should expect contracting officers to reopen conversations about contract type on options and modifications well before that date, and some may press to convert covered work to fixed-price rather than assemble the justification paperwork. Firms priced their proposals on a risk allocation that the government is now actively trying to shift, and margins built on cost-plus certainty deserve a fresh look. The most immediate exposure sits with new bids: any proposal that assumes a covered contract type should confirm the justification exists and has cleared the right approval level before the solicitation closes, because a rejected justification can force a mid-competition change to fixed-price terms that no bidder priced for.
