What Is a Service Contract Act (SCA) Contract? A Federal Contractor’s Guide
Meta description: Learn what a Service Contract Act contract is, which federal service contracts it covers, how wage determinations work, and what contractors must do to comply.
A Service Contract Act (SCA) contract is a federal contract for services that may require contractors and subcontractors to pay covered workers at least the wages and fringe benefits set by the U.S. Department of Labor (DOL). The law is now commonly called the McNamara-O’Hara Service Contract Labor Standards (SCLS) statute, though “SCA” remains widely used. Knowing when the law applies helps agencies and contractors price work correctly, prepare required records, and avoid wage violations.
What Is the Service Contract Act?
The Service Contract Act is a federal labor law enacted in 1965. It establishes labor standards for certain contracts between the federal government and private businesses to provide services in the United States. The DOL administers the law through its Wage and Hour Division.
In general, a covered contract must be principally for services, be made by a federal agency, and be performed in the United States or its territories. It must also exceed $2,500. The statute’s coverage and requirements depend on the contract’s terms, the work performed, and any applicable exemptions.
When a covered contract exceeds the threshold, it generally must include the applicable SCA labor standards clause and a DOL wage determination. Those documents specify the minimum compensation and other labor requirements for covered service employees. Contractors remain responsible for compliance even when they use subcontractors to perform part of the work.
What Work Can an SCA Contract Cover?
SCA contracts cover many services purchased by federal agencies. Common examples include building maintenance, janitorial work, food services, guard services, clerical support, groundskeeping, laundry, and certain technical or professional support services. The deciding factor is usually the nature of the contract—not the company’s industry or the job title alone.
A contract may include both services and supplies. If furnishing services is its principal purpose, SCA requirements may apply to the service work. Conversely, a contract principally for products may fall under different labor standards, such as the Walsh-Healey Public Contracts Act. Agencies and contractors should review the actual scope and applicable regulations rather than rely only on a contract’s name.
Whether individual workers are covered also depends on their duties and circumstances. The statute generally concerns service employees performing work on or in connection with the contract. Some categories of workers or contracts may be exempt, but an exemption should be confirmed against the governing law and DOL regulations.
How SCA Wage Determinations Work
A wage determination is a DOL document that sets minimum monetary wages and fringe benefits for specified service occupations in a particular locality. The contracting agency typically incorporates the applicable determination into the solicitation and contract. Contractors use it to identify the minimum compensation required for the covered job classifications and work location.
Wage determinations are occupation- and location-specific. A determination may list classifications such as janitor, security guard, food-service worker, or administrative support worker, with separate compensation requirements. A contractor must use a classification that reasonably matches the work performed; a convenient but inaccurate job title does not determine the correct rate.
For covered employees, the contractor generally must pay at least the listed wage and provide the listed fringe benefits. The fringe requirement may be met through qualifying benefits, such as health or pension contributions, or through cash payments as permitted by the rules. Contractors should calculate total obligations carefully: a wage rate and a fringe amount are distinct requirements, and paying above the listed wage does not automatically satisfy the fringe obligation.
The applicable determination may change when a contract is renewed, extended, or otherwise modified, depending on the contract and regulations. Contracting officers and contractors should verify the determination attached to the solicitation and later contract documents. DOL’s Wage Determinations database is a key source for locating determinations, but the agency’s contract documents establish which determination applies to the particular award.
Successor Contracts and Collective Bargaining Agreements
Special rules can apply when a new contractor takes over a service contract previously performed by another contractor. Under the SCA’s successor-contractor provisions, a successor may be required to pay service employees at least the wages and fringe benefits provided by a predecessor contractor’s collective bargaining agreement (CBA), subject to statutory conditions and exceptions.
This requirement can affect a contractor’s bid. A successor should determine whether a predecessor CBA exists, identify the covered employees and terms, and assess whether the statutory successor rule applies. The rule does not mean every successor automatically adopts every term of a predecessor’s labor agreement. Its effect depends on the contract, timing, bargaining history, and applicable exceptions.
Contractor Responsibilities Under the SCA
Compliance is an ongoing responsibility, not a one-time bidding task. Contractors should review the solicitation before submitting a price, confirm the wage determination and classifications, and account for wages, fringe benefits, payroll administration, and possible changes during performance. Subcontracting does not remove a prime contractor’s responsibility to address labor-standard requirements in the contract.
- Pay required compensation: Meet the applicable minimum wage and fringe-benefit requirements for covered employees.
- Use accurate classifications: Match each worker’s actual duties to the appropriate listed occupation or seek agency guidance when no classification fits.
- Maintain records: Keep payroll and employment records required by the regulations and contract, including information needed to show compliance.
- Provide required notices: Make the wage determination and other required labor information available to employees as specified by the contract and regulations.
- Flow down requirements: Include the applicable labor standards provisions in covered subcontracts and monitor subcontractor performance.
- Address changes promptly: Review contract modifications, option periods, and revised wage determinations to determine whether compensation obligations have changed.
Federal contracting clauses commonly include FAR 52.222-41, “Service Contract Labor Standards,” when the clause is required. The contract’s incorporated clauses and wage determination should be reviewed together. Contractors should not assume that a clause is irrelevant simply because the work is performed at a contractor facility or because employees are not government workers.
Exemptions and Situations Requiring Special Review
Not every federal services agreement is covered. The statute and DOL regulations provide exemptions and exclusions for certain contract types and circumstances. Examples include some contracts for specific utility services, certain transportation services, and work performed by bona fide executive, administrative, or professional employees under the applicable standards.
A separate regulatory exemption may apply to certain commercial services when its conditions are met. The details are technical, and the exemption is not a blanket exception for all commercially available services or all professional work. Contracting officers and contractors should verify the precise regulatory criteria before treating a contract or employee as exempt.
Work outside the United States, mixed-purpose contracts, and contracts involving other federal labor laws may also require careful analysis. The applicable result can turn on where the service is performed, what the contract principally requires, and which statutory exemption—if any—fits. When coverage is uncertain, the parties should consult the contract’s labor clauses, DOL regulations, and the contracting agency rather than make assumptions based on a short description of the work.
What Happens If a Contractor Violates the SCA?
The DOL may investigate complaints or conduct compliance reviews. If it finds violations, a contractor may be required to pay back wages and fringe benefits owed to employees. The government may withhold contract funds to cover amounts due, and serious or repeated violations can lead to additional consequences, including restrictions on federal contracting under applicable debarment procedures.
Common compliance problems include paying the wrong occupation rate, failing to provide the required fringe amount, misclassifying employees, overlooking successor-contract rules, and not keeping adequate records. Errors can affect multiple workers and pay periods, so even a mistaken classification or calculation may create a substantial liability.
Sound contract administration can reduce risk. Before performance begins, contractors can map job duties to the wage determination, calculate compensation costs, and establish payroll checks. During performance, periodic reviews can catch changes in duties, location, staffing, or contract terms before they become larger problems.
SCA Contract vs. Other Federal Labor Standards
The SCA is distinct from other federal labor laws, although a contract can raise questions involving more than one law. The Davis-Bacon Act generally applies to covered federal construction contracts and establishes prevailing wage requirements for construction workers. The Walsh-Healey Act addresses labor standards for certain federal supply contracts. The SCA focuses on covered federal service contracts.
| Labor standard | Typical contract focus | Primary wage framework |
|---|---|---|
| Service Contract Act (SCA/SCLS) | Covered federal service contracts | DOL service-occupation wage determination and fringe requirements |
| Davis-Bacon Act | Covered federal construction work | Construction wage determination for the project locality |
| Walsh-Healey Public Contracts Act | Certain federal contracts for supplies | Statutory labor standards for covered manufacturing or furnishing work |
The laws should not be treated as interchangeable. A contracting officer’s determination, the principal purpose of the contract, and the nature of the work help establish which standards apply. If a contract combines construction, services, and supplies, the governing requirements may require a more detailed review.
How to Check Whether a Contract Is Covered
A practical initial review can help identify potential SCA obligations, though it does not replace a formal legal or agency determination:
- Identify the customer and contract: Confirm whether the agreement is a federal agency contract and review its stated scope.
- Assess the principal purpose: Determine whether the government is primarily purchasing services, supplies, construction, or a combination.
- Check the value: Confirm whether the contract exceeds the $2,500 threshold relevant to SCA coverage.
- Review the labor clauses: Look for FAR 52.222-41 and related provisions in the solicitation and award.
- Find the wage determination: Verify the locality, occupations, wage rates, fringe amounts, and any incorporated revisions.
- Examine possible exemptions: Apply the specific statutory and regulatory criteria instead of relying on a general label such as “professional” or “commercial.”
For authoritative guidance, contractors can consult the DOL Wage and Hour Division’s Service Contract Labor Standards resources, the relevant provisions in Title 29 of the Code of Federal Regulations, and the Federal Acquisition Regulation. The contracting officer can clarify which clauses and wage determination were incorporated into a particular award. Because contract facts matter, specialized advice may be appropriate when coverage, exemptions, or successor obligations are disputed.
Key Takeaways
An SCA contract is generally a federal contract principally for services that meets the statute’s coverage requirements. Covered contracts typically require contractors to follow a DOL wage determination, pay required wages and fringe benefits, keep records, and ensure that covered subcontract work meets the labor standards. The law has technical exemptions and special rules, including provisions for certain successor contracts, so the contract documents and applicable regulations should be checked before pricing or beginning work.
