Can I just file the federal WH-347 in Connecticut?

No. For state-funded public-works projects Connecticut requires its own CT DOL WWS-CP1 form under C.G.S. §31-53. PayrollPenguin generates the WWS-CP1 with its Certified Statement of Compliance from your payroll.

How often do I file in Connecticut?

Records are weekly, but you submit them monthly to the contracting agency. PayrollPenguin produces a WWS-CP1 for each weekly record so your monthly submission is complete.

Is PayrollPenguin a compliance guarantee?

No. PayrollPenguin is a reporting and formatting tool — it formats your payroll to the CT DOL WWS-CP1 specification and flags anomalies. You certify and the contracting agency reviews.

Connecticut WWS-CP1 certified payroll

How to file certified payroll in Connecticut (WWS-CP1)

Connecticut requires its own certified-payroll form for state-funded public-works work — the CT Department of Labor WWS-CP1 "Payroll Certification for Public Works Projects," not the federal WH-347. Records are weekly, and you submit them monthly to the contracting agency. PayrollPenguin turns your existing payroll run into a file-ready WWS-CP1 with its Certified Statement of Compliance, and flags anomalies for your review before you sign.

Connecticut uses the WWS-CP1, not the WH-347

For state-funded projects, Connecticut mandates the CT DOL WWS-CP1 form (cover plus the WWS-CP2 continuation and a Certified Statement of Compliance) under C.G.S. §31-53. The federal WH-347 does not satisfy the state filing. PayrollPenguin maps your payroll straight onto the WWS-CP1 layout — Section A for prevailing-rate hours and Section B for other work — so you submit the form Connecticut actually accepts.

The WWS-CP1 is a public document — no SSNs

The form footer states plainly: this is a public document — do not include Social Security Numbers. PayrollPenguin renders the WWS-CP1 with no SSN anywhere on the form. Worker names and classifications appear; SSNs never do. That keeps the record safe to hand to a contracting agency that may publish it.

Weekly records, monthly submission

Connecticut certified payroll is recorded each week but submitted monthly to the contracting agency. PayrollPenguin produces one WWS-CP1 per weekly record from your payroll run and reshapes your straight-time and overtime hours into Section A. It reformats your numbers; it never invents a wage. Cells the form asks for but your payroll does not carry — apprentice rate, trade-license or OSHA-10 number, worker address — are left blank for you to complete.

How to file Connecticut certified payroll

Import your payroll run. Upload your ADP, Gusto, QuickBooks, Paychex, or CSV payroll for the pay period.
Pick the Connecticut project. Select the public-works project and confirm the contract number and contracting agency.
Review the anomalies. PayrollPenguin flags missing fringe, classification gaps, and zero-hour weeks for your review before you certify.
Certify and export the WWS-CP1. Sign the Certified Statement of Compliance, then download the file-ready WWS-CP1 PDF to submit to the contracting agency.
