Missouri Certified Payroll and Prevailing Wage Rules

Missouri runs its own prevailing wage law on top of federal Davis-Bacon. Here is what that means for a certified payroll report on a Missouri project.

✓ HAS ITS OWN PREVAILING WAGE LAW

Federal Davis-Bacon is not the only rule that applies here. Applies to public works projects valued over $75,000, built by or on behalf of state and local public bodies. That runs on top of, not instead of, the federal WH-347 whenever the project also has federal money in it.

What this means for your paperwork

Whenever a Missouri project has federal money in it, the WH-347 side of it still has to happen on top of the state paperwork. Certified Payroll only handles the federal side: it checks the rate against the live SAM.gov wage determination and fills out the WH-347 with its Statement of Compliance. It does not file Missouri's own state form, so budget for that as a separate step if this project needs it.

Frequently asked

Does Missouri have its own prevailing wage law?+

Yes. Missouri Revised Statutes §§ 290.210-290.340 set the state's own prevailing wage requirement.

Does Certified Payroll file Missouri's state certified payroll form?+

No. Certified Payroll files the federal WH-347 under Davis-Bacon, not Missouri's own state form. The moment a Missouri project is also federally funded, it checks the rate and fills out the WH-347 automatically. The state form is still a separate filing.

This is a general informational summary, not legal advice, and covers state-level rules only. Verify current requirements with Missouri's labor department or a qualified compliance advisor before relying on it.

Certified Payroll checks every rate against the live wage determination as you enter hours, then generates the completed WH-347 with its Statement of Compliance.
