Service Contract Labor Standards (SCLS) and Your GSA Schedule: A Compliance Guide

SCLS Compliance Isn't Optional — And Getting It Wrong Is Expensive

The Service Contract Labor Standards (SCLS), formerly known as the Service Contract Act (SCA), applies to every GSA MAS contract that includes service offerings. If you have service SINs on your Schedule, SCLS is part of your contract whether you realize it or not. And noncompliance can result in back pay liabilities, contract termination, and debarment.

As a former Contracting Officer, I've seen contractors get blindsided by SCLS requirements because they didn't understand how wage determinations work or how the rules interact with their GSA pricing. Let me walk you through what you need to know.

What Is SCLS?

SCLS requires contractors providing services to the federal government to pay their employees no less than the prevailing wage rates and fringe benefits for the geographic area where the work is performed. These rates are established by the Department of Labor through Wage Determinations.

In simple terms: if you're performing service work on a GSA Schedule order, you must pay your workers at least the minimum wage and benefits specified in the applicable Wage Determination for that location and labor category.

How SCLS Applies to Your GSA Schedule

  • It's Built Into Your Contract — SCLS clause 52.222-41 is included in your GSA MAS contract if you have service SINs. This means every task order placed against those SINs is subject to SCLS requirements.
  • Wage Determinations Vary by Location — Different geographic areas have different prevailing wage rates. When you receive a task order, you need to check the Wage Determination for the performance location to ensure you're paying compliant rates.
  • Fringe Benefits Are Included — SCLS doesn't just cover wages. It includes health and welfare benefits, vacation, and holiday pay. You must provide the fringe benefits specified in the Wage Determination or pay the monetary equivalent.
  • It Affects Your Pricing — Your GSA labor rates need to account for SCLS wages and benefits. If you price your services without considering SCLS, you may end up losing money on every hour billed.

Common SCLS Mistakes on GSA Schedules

  • Not Checking Wage Determinations — Contractors accept task orders without verifying the applicable Wage Determination. This leads to paying workers less than the required rate, creating a compliance violation and back pay liability.
  • Confusing Exempt and Non-Exempt Workers — Not all service workers are covered by SCLS. Professional, administrative, and executive employees who meet certain criteria may be exempt. But the burden of proof is on you to demonstrate the exemption applies.
  • Ignoring Fringe Benefit Requirements — Some contractors pay the base wage but shortchange fringe benefits. SCLS requires specific health and welfare amounts, and the penalties for noncompliance are real.
  • Not Updating for New Wage Determinations — Wage Determinations are updated periodically. If a new WD is issued during your period of performance, you may need to adjust your wages — and potentially request a price adjustment from the ordering agency.

How to Stay Compliant

  • Check SAM.gov for Wage Determinations — Before accepting any service task order, look up the applicable Wage Determination on SAM.gov. Match your labor categories against the WD categories and verify your rates are compliant.
  • Build SCLS Costs Into Your GSA Pricing — When setting your GSA labor rates, factor in the highest likely SCLS wage and benefit requirements you'll encounter. This prevents margin erosion when you get orders in high-wage areas.
  • Maintain Compliance Records — Keep detailed records of wages paid, benefits provided, and the Wage Determinations you relied on for each task order. If audited, this documentation is your best defense.
  • Train Your HR and Payroll Teams — SCLS compliance isn't just a contracts issue. Your HR and payroll teams need to understand the requirements and flag any orders where wages may need adjustment.
  • Request Price Adjustments When Needed — If a new Wage Determination increases your costs, you have the right to request a price adjustment from the ordering agency. Don't absorb the cost silently — use the process that's available to you.

The Bottom Line

SCLS is one of those compliance areas that can sneak up on you if you're not paying attention. The requirements are clear, the penalties are real, and the cost of noncompliance far exceeds the cost of getting it right from the start.
