FAR Part 52: Key Contract Clauses Every Federal Contractor Must Know
FAR Part 52 clauses are incorporated into every federal contract. Know which clauses apply to your work, what rights they give you, and what obligations they impose.
Every federal contract contains a set of standard clauses drawn from FAR Part 52 — the Federal Acquisition Regulation's library of mandatory and discretionary contract provisions. These clauses are not negotiable — the FAR requires agencies to include certain clauses in every contract, regardless of what the contractor prefers.
Not knowing what these clauses require is not a defense when you violate them. This guide covers the most important FAR clauses that affect small business federal contractors.
How FAR Clauses Work
FAR Part 52 clauses are incorporated into contracts in two ways:
- Full text: The complete clause is physically printed in the contract (Section I of the solicitation/contract)
- Incorporation by reference: Only the clause number and title appear; the full text is available at the FAR website. This is the most common method for long or frequently updated clauses.
Flow-down clauses: Many prime contract clauses must be "flowed down" to subcontractors. When a prime receives a clause that says "the contractor shall include this clause in all subcontracts over $X," the prime is legally required to include that clause in relevant subcontracts.
Administration and General Clauses
FAR 52.202-1 — Definitions
Defines key terms used throughout the contract. Always check this clause when a contract uses terms with specific technical meanings (e.g., "affiliate," "responsible," "responsible prospective contractor").
FAR 52.203-5 — Covenant Against Contingent Fees
Prohibits contractors from paying contingent fees (commissions, kickbacks) to anyone for securing the contract. Violation can result in contract termination and debarment.
FAR 52.203-7 — Anti-Kickback Procedures
Requires contractors to maintain procedures to detect and prevent kickbacks; prohibits kickbacks from subcontractors to prime contractor employees. Penalties include criminal prosecution.
FAR 52.203-12 — Limitation on Payments to Influence Certain Federal Transactions
The "anti-lobbying" clause. Prohibits using federal funds to lobby Congress or federal agencies about contract awards. Requires certification of compliance. Violations can result in civil penalties up to $150,000 per transaction.
FAR 52.204-21 — Basic Safeguarding of Federal Contractor Information Systems
Required in contracts where you will process or store Federal Contract Information (FCI). Imposes 15 basic security requirements from NIST SP 800-171. This is the baseline cybersecurity clause for civilian agency contracts. For DoD contracts with CUI, DFARS 252.204-7012 applies instead.
FAR 52.215-2 — Audit and Records (Negotiation)
Gives the government the right to audit your books, records, and cost documentation related to the contract. Required for cost-reimbursement contracts and contracts requiring TINA certification. You must retain records for three years after final payment.
Small Business Clauses
FAR 52.219-1 — Small Business Program Representations
Requires you to represent your small business status, and if applicable, your 8(a), HUBZone, WOSB, or SDVOSB status. Misrepresenting your small business status is a False Claims Act violation.
FAR 52.219-6 — Notice of Total Small Business Set-Aside
This clause appears in every small business set-aside contract. It defines the requirement that you perform at least 50% of the cost of the contract (for services) with your own employees. Exceeding the subcontracting limitation is a compliance violation.
FAR 52.219-8 — Utilization of Small Business Concerns
Requires contractors to use small businesses (including SDB, women-owned, veteran-owned, HUBZone) to the maximum extent practicable as subcontractors. Contracting officers ask for subcontracting plans before award on large contracts.
FAR 52.219-9 — Small Business Subcontracting Plan
For prime contracts over $750,000 (construction over $1.5M) awarded to other-than-small businesses, this clause requires a formal subcontracting plan with goals for each small business category. If you are a small business, this clause typically does not apply to you — but it appears in your subcontract agreements with large primes.
FAR 52.219-14 — Limitations on Subcontracting (SB Set-Aside)
Specifies the maximum work that can be subcontracted for each set-aside program:
- Services: Subcontracts cannot exceed 50% of non-material contract cost
- General construction: Cannot subcontract more than 85%
- Special trade: Cannot subcontract more than 75%
- Supply: Cannot exceed 50% of the cost of manufacturing
Labor and Employment Clauses
FAR 52.222-1 — Notice to the Government of Labor Disputes
Requires you to notify the contracting officer if labor disputes may interfere with contract performance. Relevant if your workforce is unionized.
FAR 52.222-26 — Equal Opportunity
Prohibits employment discrimination based on race, color, religion, sex, sexual orientation, gender identity, or national origin. Requires an affirmative action program for contractors with 50+ employees and contracts over $50,000.
FAR 52.222-35 — Equal Opportunity for Veterans
Requires affirmative steps to employ and promote veterans. Applies to contracts over $150,000.
FAR 52.222-36 — Equal Opportunity for Workers with Disabilities
Similar to the veterans clause — requires affirmative steps to employ workers with disabilities.
FAR 52.222-41 — Service Contract Labor Standards (SCA)
For services contracts, requires paying employees at least the prevailing wage rates and fringe benefits determined by the Department of Labor for the relevant locality and service occupation. This is the Service Contract Act (SCA) compliance clause.
Violating the SCA (paying employees below the SCA wage determination rates) is a serious violation — your employees can recover back wages and the government can terminate the contract.
FAR 52.222-50 — Combating Trafficking in Persons
Prohibits contractors, subcontractors, employees, and agents from engaging in trafficking in persons. Requires compliance plans for contracts over $500,000 outside the US. Zero tolerance — any violation results in termination.
Intellectual Property Clauses
FAR 52.227-14 — Rights in Data (General)
Defines the government's rights to technical data and computer software generated under contracts. Generally, the government receives unlimited rights to work created specifically for the government. If you use pre-existing proprietary data in performance, negotiate to limit the government's rights to that pre-existing material.
FAR 52.227-11 — Patent Rights (Ownership by the Contractor)
Based on the Bayh-Dole Act — contractors can retain patent rights to inventions developed under federal contracts if they follow the required disclosure and assignment procedures. Critical for R&D contractors. If you invent something under a government contract and want to retain the patent, follow the procedures in this clause.
Termination Clauses
FAR 52.249-1 — Termination for Convenience (Fixed-Price)
The government can terminate your contract "for convenience" at any time — without fault on your part. If terminated for convenience, you are entitled to:
- All costs incurred prior to termination
- Profit on work performed
- Costs of settling subcontracts
- Reasonable termination costs (severance, demobilization)
You are NOT entitled to: Your anticipated profits on unperformed work.
This is a fundamental difference from commercial contracts — the government can walk away from any contract for any reason, and you can recover only your costs plus profit on completed work.
FAR 52.249-8 — Default (Fixed-Price Supply and Service)
Allows the government to terminate for "default" (contractor failure to perform) without compensation. The government can then reprocure elsewhere and hold the defaulted contractor liable for excess reprocurement costs.
Difference from termination for convenience: Termination for default is a penalty. You are not compensated for work in progress and may be held liable for the government's costs to replace you.
Payment Clauses
FAR 52.232-1 — Payments
Establishes the basic payment terms — typically Net 30 from receipt of a proper invoice.
FAR 52.232-25 — Prompt Payment
Requires the government to pay interest (at the Treasury rate) on invoices not paid within the payment due date. If the government owes you money and is late, you are entitled to interest.
FAR 52.232-33 — Payment by Electronic Funds Transfer
Requires payment by EFT to the bank account on your SAM.gov registration. If your SAM.gov bank information is wrong or expired, you will not get paid.
Key Takeaways
- FAR Part 52 clauses are non-negotiable — they are legally required in federal contracts and cannot be waived.
- Small business clauses (52.219-6, 52.219-14) define the subcontracting limitations for set-aside contracts — violating them is a False Claims Act issue.
- The Service Contract Act (52.222-41) requires payment of DOL wage determination rates — ignorance is not a defense.
- Intellectual property clauses (52.227-11, 52.227-14) define what IP the government owns vs. what you retain — negotiate these carefully for R&D work.
- Termination for convenience (52.249-1) means the government can end your contract at any time — you recover costs and profit on completed work, not anticipated future profits.
- Payment by EFT (52.232-33) — your SAM.gov bank information must be current or payments will fail.
