What You Need to Know About Certified Payroll for Subcontractors
Subcontractors working on federally sponsored construction projects must follow the rules for certified payroll.
If you serve as a subcontractor on a government-funded construction project, you must run Certified Payroll for Subcontractors for your workers and provide those reports to the general contractor every week.
If you miss that deadline, your payment might be delayed, and if you keep missing deadlines, your business relationship could be in danger.
This is a frequent problem. One of the most typical compliance issues in the business is Certified Payroll for Subcontractors.
For instance, the U.S. Department of Labor’s Wage and Hour Division (WHD) got back around $15 million in back wages for more than 3,500 workers in fiscal year 2023 alone. This was done under the Davis-Bacon and Related Acts, which are the laws that control certified payroll on federal projects.
The paperwork isn’t the hard part. It’s hard to know what the general contractor is looking for, what you need to do, and what may happen if anything goes wrong.
Why Your General Contractor Is Counting on You
Subcontractors who are certified to follow the rules for payroll directly impact the general contractor’s ability to remain compliant on a project that is sponsored by the government.
It’s the law that general contractors make sure that everyone on the project, including you, follows the rules for Certified Payroll for Subcontractors.
That implies that if you work on a project that is supported by the federal government, you have to send in certified payroll records. These reports are also what keeps the general contractor in line.
The general contractor will examine your submissions to make sure that reports were sent on schedule, wage rates reflect the project’s pay determination, and labor classifications are correct.
Even if the problem starts with the subcontractor, the prime contractor may still be held liable if there is a difference in your reports.
That means the general contractor is at risk of a lot of liability, which is why it’s so important to send in certified payroll reports on time and accurately to keep that connection going and be considered for future work.

Federal and State Prevailing Wage Laws Both Apply
Both federal and state prevailing wage regulations set the rules Certified Payroll for Subcontractors
The Davis-Bacon Act sets rules for certified payroll on federally financed construction projects. It requires weekly filings and conformity with federal wage decisions.
But that’s just half of the story.
Most states have their own “little Davis-Bacon” laws that set varying rates, criteria, and ways to report them. Some are stricter than the federal norm.
The main contractor is in charge of telling you what regulations apply to their project. It’s a good idea to make sure your team knows what they need to do to get the job done.
If you’re working in more than one state, it’s best to check which regulations apply to each job instead of assuming that one set of laws applies to all of them.
How Data Collection for Subcontracting Actually Works
Certified payroll reporting for subcontractors isn’t a one-time task — it’s a weekly process. Without a clear workflow, it’s easy for submissions to slip.
What Subcontractors Are Required to Do
It’s not a one-time job to submit Certified Payroll for Subcontractors; it’s something you do every week. It’s simple for contributions to be lost if there isn’t a defined protocol.
What Subcontractors Have to Do
For every Davis-Bacon-covered project, subcontractors must follow the rules for certified payroll, which include how workers are paid, reported, and recorded every week.
Subcontractors have three main responsibilities:
- Pay the going rate: All workers on a covered project must be paid at least the pay rate specified in the project’s wage determination for their trade classification, plus any needed fringe benefits.
- Every week, run certified payroll reports that show all of your employees, their hours, their job title, and their gross salaries for that week. You can usually do this using Form WH-347 or a state-required equivalent.
- Send such reports to the general contractor every week, by the date that the general contractor gives you.
It is the job of the general contractor to gather your submissions and send them to the contracting agency.
General contractors need such contributions to follow the rules set forth in the Davis-Bacon Act.
Your general contractor may tell you to upload directly via a compliance platform like LCPtracker or eMars, which the agency can also see. However, the general contractor is still responsible for making sure your reports go to the contracting agency.
Things become a lot more complicated when workers travel state boundaries or work in more than one city.
The process of collecting data usually includes:
- Time records sorted by project and type
- Tracking fringe benefits to make sure the overall pay reaches the statutory rate
- Signed declarations of conformity, which are normally WH-347 or a state equivalent
- Uploading files electronically to sites like LCPtracker, eMars, or DiR
- When this procedure is done by hand, it takes a long time and is likely to make mistakes.
If you change a wage rate or label a classification wrong, you might get a deficiency notice. This means you have to go through weeks of verified payroll records to locate and remedy the error.
What Happens When Subcontractors Don’t Submit
If you don’t send in certified payroll reports on time, you risk not being paid, and the subcontractor, the general contractor, and even the project owner in certain situations might face legal action.
Withholding progress payments is frequently the first thing that happens to the subcontractor.
Before authorizing bills, contracting officers must mark any missing submissions. This is because reports that are still due might hold up payment for the sub.
If a pattern starts to form, the stakes go up for everyone.
Subcontractors might have to pay back wages, penalties, and lose the right to work on public projects in the future.
The prime contractor is also responsible for making sure that everyone on the project is paid the right amount, thus they face the same risks, such as having to pay back wages to workers on the sub’s crew.
Debarment may stay with a firm for years and prevent them from doing a whole kind of job.
Even if problems start with the subcontractor, the general contractor is still legally responsible and may have to pay for workers’ damages.
One reason why it counts so much for long-term professional relationships is that they follow the rules all the time.
Understanding Flow-Down Clauses
Flow-down clauses are parts of a contract that make it legally possible for general contractors to pass on their responsibilities, including verified payroll requirements, straight to subcontractors.
You committed to such compliance duties when you signed the contract as a subcontractor.
Most public works contracts clearly say that all subcontractors must follow the Davis-Bacon rules, pay the prevailing wage, and meet the reporting criteria.
When you sign the subcontract, you agree to those conditions, so it’s a good idea to read them over carefully before you start working.
More and more, general contractors are using project management software to keep an eye on subcontractor submissions in real time. This makes it simpler to find gaps early.
Before you start working, carefully read the flow-down terms in your subcontract. This is not to see whether the law applies, but to make sure you know precisely how compliance works on a particular project.
If you’re working on a federal project that is protected by Davis-Bacon, the rules still apply even if the flow-down wording was accidentally taken out of your subcontract.
It all depends on the processes you put in place to satisfy those duties.
The Bottom Line: Compliance Shouldn’t Be Hard
Every part of a public works project is affected by certified payroll for subcontractors.
General contractors carefully go over all submissions.
Agencies that hire people do audits. And the consequences of making a mistake—like not being paid, having to pay back wages, or being banned—don’t just affect the person who made the error. They go up and down the chain of the project.
