How to file certified payroll in Missouri (prevailing wage, WH-347)

The Annual Wage Order sets the rates

For public-works projects, Missouri’s Division of Labor Standards publishes an Annual Wage Order with the prevailing wage rates for each county and occupational title. Those rates come from the AWO, not from PayrollPenguin — the tool reshapes your own payroll numbers into the report and surfaces a rate below the determination as an anomaly for your review. It never invents a wage.

Missouri accepts the WH-347 format

Missouri offers its own LS-57 contractor payroll form, but the federal WH-347 format is also accepted for certified payroll on state prevailing-wage work. PayrollPenguin produces a WH-347-format report — the same layout most general contractors and public bodies already expect — so you do not have to re-key your payroll into a separate state form.

Filed weekly with the public body

Certified payroll is submitted each week to the public entity that issued the contract — there is no mandatory statewide electronic portal for general certified payroll in Missouri. Some individual public bodies use third-party upload systems, but the underlying report is the same. PayrollPenguin gives you a file-ready report you can submit however your awarding agency requires.

How to file Missouri certified payroll

1. Import your payroll run. Upload your ADP, Gusto, QuickBooks, Paychex, or CSV payroll for the pay period.
2. Pick the Missouri project. Select the public-works project and note its Annual Wage Order number and contract/project number.
3. Resolve flagged anomalies. PayrollPenguin flags issues like a rate below the wage determination, missing fringe, or a zero-hour week for your review before you certify.
4. Certify and export the report. Sign the Statement of Compliance, then download the WH-347-format report to submit to the contracting public body each week.

Frequently asked questions

Does Missouri accept the federal WH-347?

Yes. For state prevailing-wage public-works projects, Missouri’s Division of Labor Standards offers its own Form LS-57 and also accepts the federal WH-347 format for certified payroll. PayrollPenguin produces a WH-347-format report so you can file without re-keying into a separate form.

Where do I submit Missouri certified payroll?

Each week to the contracting public body that issued the project — the awarding agency or its general contractor. There is no mandatory statewide electronic certified-payroll portal in Missouri, though some public bodies use their own upload systems.

Is PayrollPenguin a compliance guarantee?

No. PayrollPenguin is a reporting and formatting tool — it formats your payroll to the WH-347 specification and flags anomalies for your review. You certify and the contracting public body reviews.
