Fixed-Price Is Now the Default: What the FAR Part 16 Overhaul Means for Your Next Federal Bid

If you bid on federal contracts, the ground just shifted under your pricing strategy. On July 1, 2026, the FAR Council published updated text for Part 16 implementing Executive Order 14402, which establishes fixed-price contracts as the federal government’s preferred contract type. The first compliance deadline arrived July 15, 2026, and the implications reach every contractor who has ever relied on cost-reimbursement, time-and-materials, or labor-hour arrangements to manage risk.

What Changed on July 1

Under the overhauled Part 16 text, fixed-price contract types are now explicitly the default and preferred contract types government-wide. The revised regulation directs that when a fixed-price arrangement is not appropriate for an entire contract, contracting officers should consider whether at least a portion of the work can be established on a fixed-price basis. Agencies that want to award a non-fixed-price contract above specified dollar thresholds must now obtain a written justification approved at the agency-head level. That approval requirement extends to existing contracts and orders with at least 18 months of performance remaining as of July 15, 2026.

Why This Shifts Risk Onto Contractors

The policy logic is straightforward: fixed-price contracts give the government cost certainty and put performance risk on the contractor. But procurement attorneys are warning that the practical burden runs deeper than the label suggests. Some emerging fixed-price structures tie payment to delivered hours — meaning contractors who fail to deliver the specified level of effort can lose money, while cost overruns remain entirely theirs to absorb. Firms accustomed to loose time-tracking on fixed-price work are discovering they must now monitor time entry rigorously, match timecards to invoices, and produce payroll documentation to get paid.

Five Moves for Small Business Contractors

1. Price with discipline, not hope. Under fixed-price arrangements, an underestimate comes straight out of your margin. Build bottom-up cost models with realistic labor categories, escalation, and contingency.

2. Scrutinize the statement of work before you commit. Vague or open-ended SOW language that would have been an annoyance on a cost-type contract becomes a genuine financial hazard on a fixed-price one. Ask clarifying questions during Q&A, and price identified ambiguity as risk.

3. Propose hybrids where they fit. The overhauled Part 16 explicitly contemplates structuring portions of a contract as fixed-price while other portions use different types, and contracting officers can invite alternative contract-type proposals.

4. Strengthen your proposal narrative around risk management. With fixed-price as the default, evaluators will look harder at whether an offeror can actually perform at the proposed price. Your technical approach, staffing plan, and past performance narratives need to demonstrate cost realism and delivery discipline.

5. Watch your existing contracts. If you hold a cost-type or T&M contract with 18 or more months of performance remaining, your contracting officer may be preparing a justification or considering a restructure between now and July 2027. Open that conversation early.

The Bottom Line

Fixed-price work rewards firms that estimate well, manage tightly, and deliver on time — advantages that agile small companies often hold over larger, slower competitors. The firms that lose in this environment are the ones that keep bidding the old way. Sharpen the pricing, tighten the books, and treat every SOW like the risk document it now is. Brick by brick, discipline wins.

Frequently Asked Questions

What is a fixed-price contract?

A fixed-price contract sets a firm price for defined work, regardless of what it actually costs the contractor to perform. The government gains cost certainty; the contractor carries the risk of overruns — and keeps the benefit of efficiencies. It is now the federal government’s preferred contract type under the overhauled FAR Part 16.

Are time-and-materials contracts going away?

Not entirely, but they now require agency-head-level written justification above certain dollar thresholds. Expect T&M and cost-reimbursement arrangements to become rarer, more scrutinized, and reserved for requirements where uncertainty genuinely cannot be priced.

Does the fixed-price preference apply to contracts I already hold?

It can. Existing non-fixed-price contracts and orders with 18 or more months of performance remaining as of July 15, 2026 fall under the justification requirement, with approvals due by July 15, 2027 — which means some current contracts may be restructured. Talk to your contracting officer early.
