Fixed-price government contracting is now the default way federal agencies buy, and contractors keep asking whether that helps or hurts margin. The answer depends on the contract. A firm-fixed-price contractor keeps the difference when cost stays below the price, and FAR 15.404-4 sets statutory fee limits for cost-plus-fixed-fee contracts and lists none for firm-fixed-price work. The same contractor absorbs every dollar of overrun, and under Executive Order 14402, signed April 30, 2026, a cost-reimbursement, time-and-materials, or labour-hour contract that reaches the agency threshold needs the agency head's approval.
The change also reaches work already under contract. A cost-type contract at or above the threshold with 18 or more months of performance left as of July 15, 2026, options included, needs an approved justification by July 15, 2027, and the agency may ask the contractor to renegotiate before then. Four 2026 actions shape the rules: the executive order, a July FAR Part 16 deviation, a September 14 Department of War memo on accounting and profit, and a September 18 proposed FAR rule open for comment until October 19. Each one changes a different part of pricing, profit, or the decision to bid.
Why Did Fixed-Price Become the Federal Default in 2026?
Executive Order 14402, titled Promoting Efficiency, Accountability, and Performance in Federal Contracting, was signed on April 30, 2026. It makes fixed-price contracts with performance-based considerations the default and preferred method of procurement to advance cost predictability and budget discipline. Agencies must justify any non-fixed-price contract in writing.
Agency-head approval applies at set contract values under the order and the FAR Council's July deviation, measured on the non-fixed-price part of a hybrid contract:
- $100 million for the Department of War
- $35 million for NASA
- $25 million for the Department of Homeland Security
- $10 million for all other agencies
Emergency response, major disasters, contingency operations, and research and development or pre-production development for major systems are excepted. A contractor can see which threshold applies by checking which agencies buy its kind of work, and award records by awarding agency list them.
What Is a Fixed-Price Contract in Government Contracting?
A fixed-price contract sets the price before work starts and holds it whatever performance costs. FAR 16.202-1 describes the firm-fixed-price type as a price not subject to adjustment based on the contractor's cost experience, which places maximum risk and full responsibility for costs on the contractor. The same section describes maximum incentive to control costs and a minimum administrative burden.
FAR Part 16 sorts fixed-price contracts into several types, and each handles price movement differently.
Fixed-price incentive and award-fee contracts need no executive order justification when the incentive or fee rests solely on factors other than cost, and Wiley expects these types to increase.

The rules arrived in stages, and the open deadlines fall between October 2026 and July 2027.
A covered solicitation released on or after July 15 needs its approval in hand first, so cost-type solicitations at or above the thresholds can be delayed while the agency head reviews them, as Wiley notes.
What Happens to Contracts That Are Already Running?
Running contracts and orders are covered when 18 or more months of performance remain, options included, as of July 15, 2026, and justifications for them must be approved by July 15, 2027. Wiley says contractors may face requests to justify or renegotiate pricing terms, and agencies may decline to exercise options that carry other-than-fixed-price terms. Schwabe adds that contracting officers may use option exercises, modifications, and recompetes to move cost-reimbursement vehicles toward fixed price.
A conversion price needs a realistic baseline. Jackson Holcomb warns that a fixed price built on an optimistic performance baseline, or one that leaves out risks the government should carry, invites disputes. The impact falls first on cost-type service, support and sustainment contracts, since research and development and pre-production work on major systems are excluded. Where the source publishes them, award records with performance periods show which running contracts still have 18 months or more left.
What Risks Does a Fixed-Price Contract Put on Contractors?
Risk in government contracting has moved toward the contractor. Under cost-reimbursement, estimating weaknesses may be partly absorbed through allowable-cost recovery, and under a fixed price, Protiviti notes, and those weaknesses can become losses. Morgan Lewis lists inflation, supply chain disruption, integration complexity, and changing requirements as the exposures that grow where work is complex or still evolving.
- Overruns. Every dollar above the agreed price comes out of profit.
- Inflation. Without an economic price adjustment clause, the contractor likely carries the full cost of labor rate increases and material price swings. Schwabe notes that inflation alone is generally not a basis for relief under the Changes clause or the other equitable-adjustment clauses.
- Default. A default termination can leave the contractor liable for reprocurement costs, which are the gap between the original price and what the government pays to finish the work.
- Payment tied to performance. Faegre Drinker says performance-based metrics tied to payment may become more common, which would put more weight on deliverable schedules and quality.
How Do Scope Changes and Disputes Work Under a Fixed Price?
Price adjusts only through contract clauses that provide for equitable adjustment or other revision under stated circumstances, and the Changes clause is the main one. Most firm-fixed-price contracts carry a Changes clause from FAR 52.243, and the contractor must give written notice of a claim within 30 days of the change order, or within 30 days of learning of a constructive change. Constructive changes come from informal direction by a contracting officer, COR or technical lead that adds scope or speeds the schedule.
Schwabe advises tracking cost from the day of the change and filing a request for equitable adjustment while the project team is still in place. A denied or ignored request can be converted to a certified claim under the Contract Disputes Act, which requires a signed certification above $100,000 and carries a six-year limit from the date the claim accrues. Challenges can also start before award, and Morgan Lewis names inadequate market research and unrealistic solicitation requirements as possible protest grounds.
How Do Contractors Price a Firm-Fixed-Price Bid?
Pricing a firm-fixed-price bid in government contracting starts with the basis of estimate. Protiviti lists escalation assumptions, labor productivity, material volatility, risk reserves and independent reviews as the inputs to check, and Schwabe adds price-to-win analysis, indirect rate forecasting and a defensible contingency for inflation and scope risk. Contract values on similar past awards give a starting point for the price-to-win check.
Economic price adjustment fits when performance runs past a year or labor and material costs are volatile. FAR 16.203 recognises adjustments based on established prices, on the actual cost of labor or material, and on cost indexes. A contracting officer must decide that adjustment is necessary before the clause goes in, so a contractor may need to request it in the proposal. Schwabe notes that the standard clauses cap total price increases at 10 percent unless the chief of the contracting office approves a higher cap.
What Does the Proposed FAR Part 16 Rule Change?
On September 18, 2026, the FAR Council published a proposed rule in the Federal Register, FAR Case 2026-006, covering FAR Parts 16, 17 and 35 as one of 12 proposed rules in the Revolutionary FAR Overhaul. Comments are due October 19 through Regulations.gov, citing FAR Case 2026-006. The rule would write the fixed-price default into Part 16, add justification and approval requirements for other contract types and for firm-fixed-price, level-of-effort term contracts, and let agencies use any contract type that serves the government's interest and that no statute prohibits.
Other changes affect how fixed-price work is bought and run. Usage-based services such as cloud computing could be bought as firm-fixed-price units on a consumption basis. Multiple-award contracts would gain on-ramp and off-ramp procedures and allow blanket purchase agreements. Part 17 would remove the general five-year limit on contract duration and extend the option-for-increased-quantity and option-to-extend clauses to cover supplies and services.
Is the Department of War Moving Away From Cost Accounting Standards?
The Department of War memo Fostering One Strong Industrial Base, signed September 14, 2026 by Deputy Secretary Steve Feinberg, builds on the fixed-price default. Where a market exists, with competition, comparable sales or reliable price history, the market sets the price, and cost-based contracts are reserved largely for basic research and major system development, according to Bradley. The memo also directs the department to accept GAAP-based accounting to the maximum extent the law permits.
Within 60 days, the department must send proposals to the Cost Accounting Standards Board to make CAS exemption the default and limit remaining coverage to sole-source, cost-based development or incentive-fee work. Until the board acts, no solicitation that would bring a business unit under full CAS for the first time can issue without written approval from the under secretary for acquisition and sustainment. The memo is a policy document, so contract terms in defense government contracting will likely change only as rulemakings and class deviations arrive, Bradley notes, and Protiviti points out that CAS requirements stay in place for now.
How Much Profit Can a Fixed-Price Contractor Make?
Profit in fixed-price government contracting depends on actual cost. FAR 15.404-4 sets statutory fee limits for cost-plus-fixed-fee contracts and lists none for firm-fixed-price contracts. When a price is negotiated using cost analysis, the contract cost risk factor should pay proportionally for risk, so the greatest allowance goes to a closely priced firm-fixed-price contract for a complex task done on time, and simpler work with known costs earns less. A record of economical performance on similar work earns added profit opportunity under the cost-control factor.
Defense profit policy is also in motion. The September memo orders DFARS rulemaking within 90 days so that margins reflect value, risk and invested capital as well as incurred cost. It also calls for a policy that lets a contractor that becomes more efficient against a fixed price keep the savings on that contract, with the department capturing efficiencies only in later contracts, according to Bradley.
How Do Fixed-Price Rules Apply to IDIQ Contracts and Task Orders?
The justification requirement applies differently to each kind of IDIQ vehicle in government contracting. For multiple-award contracts, the requirement skips the contract itself and attaches to the task or delivery orders and BPAs under it. A single-award IDIQ is covered when the estimated total value of known or forecast covered orders reaches the threshold, and the ceiling price decides when the contract allows only covered orders.
A hybrid contract becomes covered when its other-than-fixed-price or level-of-effort portion meets or exceeds the threshold. A contractor holding a cost-type order under a multiple-award vehicle should check the order value against the agency threshold, because the review happens at order level.
How Does Fixed-Price Risk Reach Subcontractors?
A prime on a fixed price cannot pass an overrun to the government, so supplier pricing and performance affect the prime's margin. Protiviti advises primes to check subcontractor financial discipline, reporting and cost visibility, and to rank suppliers by how critical each one is. Schwabe notes that a subcontract under a fixed-price prime is not automatically fixed-price, because level-of-effort work may call for a different structure. The Department of War memo also lets contracting officers look through primes to suppliers, with price information requested first, according to Bradley.
Finding the primes starts with prime contractor subcontracting requirements tied to each award, which list contract value, NAICS code and response deadline where published. The article on prime versus subcontractor routes covers how a company can win government work without holding the prime contract.
How Can Contractors Spot Fixed-Price Work Before the Solicitation?
Spotting fixed-price work early in government contracting begins with the contract type named in each solicitation and continues with past awards. A tender notice announces that an agency seeks bids, and an award record confirms who won, for how much and when work starts. The post on award data and tender data compares the two sources for sales teams.
Any recompete issued on or after July 15 follows the new rule, so an incumbent cost-type contract that reaches the threshold needs agency-head approval before the recompete can go out as cost-type. The post on government contract search tools covers tools for finding open opportunities and checking who won a similar contract before.
How Should a Contractor Decide Whether to Bid on a Fixed-Price Contract?
Faegre Drinker expects the push toward fixed-price to land first on well-defined requirements and recurring services, and the proposed Part 16 text calls for firm-fixed-price when risk is minimal or can be predicted with an acceptable degree of certainty.
A row in the right-hand column calls for a price reserve, an adjustment clause, a narrower scope or a no-bid decision. The cost-history row relies on agency buying history and award values for the same kind of work, which US federal, state and local procurement data covers.
Fixed-Price Government Contracting Dos and Don'ts for 2026
Do
- Read all contract types before proposing to determine what you will be doing for a cost.
- Use historical cost on similar work as the basis of the estimate whenever possible.
- Specify both the performance baseline and risks priced into your proposal in your bid submission.
- Request economic price adjustment if performance is going to run more than one year or if there are unpredictable costs (cost uncertainty) involved with the procurement.
- Send written notice within 30 days of any directive that changes scope from original solicitation and track extra cost from that date forward.
- Check option years, order values and subcontractor reporting requirements prior to signing a contract.
Don't
- Accept a conversion price for a fixed price contract that has been established on an optimistic performance baseline.
- Count on receiving relief from inflation without first including an adjustment clause in the contract terms.
- Assume that all federal acquisition regulations (FARs) have been abrogated by the September memo issued by the OMB.
- Bid vague scope at a tight price.
- Treat a multiple-award contract as exempt, since orders under it still need justification.
What Should Contractors Take From the 2026 Fixed-Price Shift?
The entire list comes from a single issue with fixed-priced government contracting that requires contractors to be responsible for their cost estimate, the Scope Record, and Supplier Terms; and if a contractor has made good cost estimates and has a viable change notice process in place, they will retain the difference if costs remain at or under the contract price.
The comment period for the proposed Part 16 rule closes on October 19th, and the new Defense Federal Acquisition Regulation Supplement (DFARS) profit policy rulemaking should follow by no later than 90 days after September 14. Therefore, contractors who hold cost-type contracts have an opportunity prior to the July 15, 2027, justification deadline to meet with the contracting officer to review the pricing terms and option years.

What is fixed-price government contracting?
Fixed-price government contracting means the agency and the contractor agree on a price before work starts. Under a firm-fixed-price contract, the price stays the same whatever performance costs, so the contractor keeps savings and absorbs overruns.
What is Executive Order 14402 in simple terms?
Signed on April 30, 2026, the order makes fixed-price contracts with performance-based considerations the default and preferred way to buy. Agencies must justify other contract types in writing, and the agency head approves large ones.
Is cost-reimbursement contracting ending?
No. Cost-reimbursement, time-and-materials and labor-hour contracts stay available with a written justification, and research and development and pre-production work on major systems are excepted. The Department of War memo says cost-based contracts are reserved largely for basic research and major system development.
How can contractors comment on the proposed Part 16 rule?
Comments on FAR Case 2026-006 are due October 19, 2026 through Regulations.gov, citing the case number. Comments can be submitted as an individual, as an organisation or anonymously.
Can the price of a fixed-price contract change after award?
Yes, through contract clauses. An economic price adjustment clause moves the price on named contingencies, a fixed-price incentive formula adjusts profit and sets the final price, and the Changes clause supports an equitable adjustment when the government directs added work.
Who pays when a fixed-price contract overruns?
The prime contractor pays because the price does not adjust to cost experience. A prime then looks at subcontractor pricing and finances, since a supplier problem affects the prime's margin.
