Most SDVOSB firms that perform labor-intensive federal service work are subject to the Service Contract Act. Many of them do not know what that actually requires until they are in a Department of Labor audit or a contract dispute. The SCA is one of the most consequential compliance regimes in federal contracting for small businesses, and its requirements flow through to your pricing, your subcontracts, and your employment records from day one of performance.
This is not a niche compliance area. The SCA covers janitorial, security, IT support, facilities management, administrative services, help desk, and dozens of other labor categories that SDVOSB firms routinely perform. If your contract is a service contract over $2,500 and the work is performed in the United States, the SCA almost certainly applies.
What the SCA Requires
The McNamara-O’Hara Service Contract Act of 1965 requires contractors on covered federal contracts to pay service employees at least the wages and fringe benefits established in the applicable wage determination for the work location. It also incorporates certain provisions of the Fair Labor Standards Act and requires compliance with safety and health standards.
The wage determination is the core document. It is issued by the Department of Labor’s Wage and Hour Division for each work location and labor category, and it establishes the minimum hourly wage and fringe benefit rate for each occupational classification of worker you will employ on the contract. The wage determination is incorporated into the solicitation and the resulting contract by clause. It is not optional — paying below the WD rate, even if the employee agrees to it, is a violation.
Finding the Applicable Wage Determination
Wage determinations are published at SAM.gov and are searchable by state, county, and type of service. When the solicitation is issued, the contracting officer is required to include the applicable WD. Your job during proposal preparation is to confirm that the WD included in the solicitation is correct for your work location and service type, and to price your labor costs accordingly.
Common errors: using the wrong county (WD rates vary significantly within a state), using an outdated WD that has since been revised, or missing a second WD when work occurs in multiple locations. Any of these errors at proposal stage becomes a pricing problem during performance, because you are locked into your proposed labor rates but still required to pay the WD minimum.
Occupational Classification
Each wage determination lists specific occupational classifications with corresponding rates — for example, “Computer Operator I,” “Administrative Assistant,” or “Security Guard II.” You must classify each covered employee under the correct classification and pay at least that rate.
Misclassification is one of the most common SCA violations. Classifying a worker at a lower rate to reduce costs — calling someone an “Administrative Support II” when their actual duties match “Administrative Support III” — exposes you to back wage liability for every hour worked at the incorrect classification. The DOL looks at actual job duties, not job titles, when assessing classification.
If no WD classification exists for a specific type of work your employees perform, you can request a conformed rate from the DOL. This is a formal process with defined timelines, and it should be initiated before performance begins, not after a DOL investigator raises the question.
The H&W Fringe Benefit Requirement
In addition to the hourly wage, you must provide each covered employee with either the prevailing health and welfare benefit (currently published annually by DOL) or a combination of bona fide fringe benefits with equivalent value. Common qualifying benefits include employer contributions to health insurance, retirement plans, vacation leave, sick leave, and holidays.
If your benefit package provides less value than the prevailing H&W rate, you must make up the difference in cash to the employee. This is where firms that offer good wages but weak benefits often discover an unexpected liability. The H&W obligation is per covered employee, per hour of work — including overtime hours.
Successor Contractor Obligations
If you win a recompete from an incumbent and the predecessor employed workers covered by the SCA, you have obligations to those workers. Specifically, SCA Section 4(c) requires you to offer employment to the predecessor’s qualifying employees, and the predecessor’s collective bargaining agreement (if any) may flow through for its term under specified conditions.
This is a significant consideration in recompete strategy. If the incumbent had a union workforce at above-WD rates, understanding your Section 4(c) exposure before you price the bid changes your cost analysis materially. Many firms discover this obligation after award, not before.
Recordkeeping Requirements
SCA contractors must maintain payroll records for each covered employee including name, address, Social Security number, work classification, hourly rate, daily and weekly hours worked, deductions, and fringe benefit contributions. These records must be kept for three years and must be available to the DOL upon request.
The three-year retention period means SCA liability follows you beyond the contract period. If the DOL opens an investigation two years after contract completion, you need records from that entire period of performance. Gaps in recordkeeping are treated as evidence of underpayment in audits — the burden of proof is on the contractor, not the government.
Subcontractor Flowdown
Your SCA obligations flow to your subcontractors. As the prime, you are responsible for ensuring that any subcontractor performing covered work on your contract also complies with the applicable wage determinations. This means your subcontracting agreements must include the SCA clause, the applicable WD, and your right to audit subcontractor payroll records.
A subcontractor violation is also a prime contractor violation for DOL purposes. This is not a theoretical risk. If your sub is paying workers below the WD rate and the DOL finds it, you share the back wage liability and you face potential debarment exposure alongside your sub. Verify SCA compliance in subcontractor selection and monitor it during performance.
Enforcement and Consequences
The DOL enforces SCA compliance through complaint-driven investigations, proactive audits (particularly on contracts above certain dollar thresholds), and review of certified payrolls when required. Violations result in back wage liability for all affected employees, withholding of contract payments by the contracting officer, contract termination for default in willful or repeat violations, and debarment from federal contracting for a period of three years.
Debarment is the enforcement mechanism that concentrates attention. A three-year debarment for SCA violations effectively ends a small contractor’s federal business. The consequence is far out of proportion to the most common cause — misclassification errors or fringe shortfalls that often result from not reading the WD carefully at proposal stage.
