How to file certified payroll in Maryland (prevailing wage, manual portal entry)

When Maryland prevailing wage applies

Maryland’s state prevailing-wage law is triggered on public-works contracts of $250,000 or more where the state funds at least 25% of the project. On those jobs you must report certified payroll electronically through the DLLR Prevailing Wage online system. Separately, federally funded Maryland work falls under Davis-Bacon and the federal WH-347. PayrollPenguin maps your payroll to the right classifications and flags a rate below the wage determination or missing fringe so your figures are correct before they reach either track.

The portal is manual entry — there is no public upload format

Maryland’s DLLR portal collects certified payroll through manual web entry. The state does not publish a public bulk-upload file schema, and the only public artifact is a downloadable “Payroll Data Form” worksheet. Because there is no defined Maryland file to generate, PayrollPenguin does not output a Maryland portal file. Instead it gives you a clean, anomaly-checked WH-347 / payroll worksheet that serves as the accurate source you type into the portal — so what you enter matches your payroll run exactly.

Deadlines, penalties, and county-level programs

Maryland state certified payroll is due within 14 calendar days of the end of each payroll period, with a $10-per-day late penalty, so a steady weekly cadence keeps you ahead of the deadline. Note that some local jurisdictions run their own programs on the LCPtracker platform — Montgomery County and Baltimore County, for example — which are separate from the state DLLR system. PayrollPenguin flags a late cadence before the deadline and keeps a certification audit snapshot of who signed what, and when.

How to file Maryland certified payroll

1. Import your payroll run. Upload your ADP, Gusto, QuickBooks, Paychex, or CSV payroll for the pay period.
2. Pick the Maryland project. Select the public-works project and attach its prevailing-wage determination so classifications and rates line up.
3. Resolve anomalies. PayrollPenguin flags a rate below the wage determination, missing fringe, or classification gaps so you can fix them before certifying.
4. Certify, then enter into the DLLR portal. Sign the Statement of Compliance and use the clean WH-347 / payroll worksheet as your accurate source to manually enter your certified payroll in the Maryland DLLR online system (or submit the WH-347 for federally-funded work).

Frequently asked questions

Does Maryland have its own certified-payroll file or form?

Maryland requires electronic submission through the DLLR Prevailing Wage online system, but that portal is manual web entry — the state publishes no public bulk-upload file schema, only a “Payroll Data Form” worksheet. So PayrollPenguin does not generate a Maryland portal file. It produces a clean, anomaly-checked WH-347 / payroll worksheet you use as the accurate source to enter into the portal.

What is the Maryland certified-payroll deadline?

Reports are due within 14 calendar days of the end of each payroll period, and Maryland assesses a $10-per-day late penalty. PayrollPenguin flags a late cadence before the deadline so your weekly filings stay on time.

What about Montgomery County or Baltimore County jobs?

Some Maryland local jurisdictions — including Montgomery County and Baltimore County — run their own prevailing-wage programs on the LCPtracker platform, separate from the state DLLR system. Confirm which program applies with the awarding agency; PayrollPenguin gives you the same clean, reviewed payroll source to work from either way.
