Certified Payroll Without the Withheld Payments

The mistake that costs the most money

Fringe benefits are part of the required rate, not something you add on top of it.

Every wage determination lists two numbers side by side for each classification: a base hourly rate and a fringe rate. What you owe is both of them added together. You can satisfy the fringe piece by contributing to bona fide plans, by paying it in cash, or by mixing the two. What you cannot do is pay only the base and call it done.

Here is where good-faith contractors get caught. Your cash rate looks generous. It is above the base on the determination and you feel fine about it. But if base plus fringe exceeds what you actually paid, you underpaid, and the fact that you were paying above base does not save you. In construction, fringe rates commonly land somewhere between 20% and 35% of the classification rate, so this is not a rounding error.

One more trap. A benefit plan has to be genuinely bona fide, meaning a legitimate established plan or program, and the administrative cost of running the plan does not count toward your fringe credit. Contractors credit the total cost of the benefit program, administration included, and come up short on the part that actually counts.

Classification is the other one

The single most common error on a WH-347 is the wrong classification. Not the math, the label.

Classification follows the work actually performed, in the place it was performed, for the type of work involved. Not the worker's job title, not what you have always called that crew, not what was convenient when you set up payroll. A worker who spends part of the week on one classification and part on another gets split across both, at each rate, with hours allocated correctly.

Apprentices are their own category. They have to be in a registered program and identified as such, with registration details. Fringe follows the approved program, and if the program says nothing about fringe benefits, the apprentice gets the full fringe listed on the determination.

And certified payroll applies to employees. If you have people on the job you are treating as 1099 contractors, that classification is going to get looked at, and losing that argument on a Davis-Bacon job is expensive twice over.

What changed on the form

DOL issued an updated WH-347 effective January 2025, valid through January 2028, and the old version stops being accepted 9-30-2026. Three things are different:

• The signature page moved. The old WH-348 Statement of Compliance is now folded into the main form.
• Fringe reporting got much more detailed. New fields separate funded benefits, meaning health plans and retirement, from unfunded ones, and ask for benefit names, types, plan numbers, hourly credit values, and the cash-in-lieu calculation. If you have been reporting one lump fringe figure, that will not fill out this form.
• Apprentice documentation is more explicit. Workers are identified as journeyworkers or registered apprentices with registration details attached.

The Statement of Compliance still needs an original ink signature from an owner, corporate officer, or an authorized designee. Signature stamps, photocopies, and faxed signatures are not acceptable. And falsifying a certification is not a paperwork problem, it is a federal criminal exposure.

Why this is an accounting problem

Most contractors treat certified payroll as a payroll department chore. It is really a cost accounting problem wearing a payroll costume, and here is why.

To produce a correct WH-347 you need hours by worker, by classification, by job, by day. Not weekly totals. Not hours by job. All four dimensions, every week. If your time tracking captures hours by employee and your job costing captures cost by project and the two never meet at the classification level, you are reconstructing the report from memory every Friday.

Then the fringe credit has to tie to something real. The hourly credit value you put on the form has to be traceable to actual plan contributions, net of administration, per worker, per hour worked on covered jobs. That number lives in your general ledger, or it should.

The structure that makes this work:

1. Classification as a dimension in payroll, not a note in a spreadsheet. Every timecard line carries worker, job, classification, and date.
2. Covered jobs flagged separately in job costing, so prevailing wage work never gets blended with private work.
3. Fringe contributions tracked per worker per hour, with administrative cost stripped out, so your credit figure is defensible rather than estimated.
4. Cash-in-lieu handled as a distinct pay item rather than folded into gross wages, because the form now asks you to show it separately.
5. Records retained three years past completion. Primes also carry records for every laborer and mechanic on the site, not just their own crew.

What non-compliance actually costs

Civil penalties run to $13,508 per violation, and violations count per worker per week, so the number compounds quickly on a job with any duration. Beyond the penalty, the contracting agency can withhold payment until the underpayment is cured, which turns a paperwork problem into a cash flow problem in the same month. The end of the road is debarment, which removes you from federal work entirely for three years.

Worth knowing that this is a busier enforcement environment than it used to be. DOL finalized the first major overhaul of the Davis-Bacon regulations in nearly forty years, and infrastructure, IRA, and CHIPS money has pushed a large number of contractors into prevailing wage work for the first time. More first-time filers means more scrutiny.

Where to start

1. Confirm which form you are producing. If it is the pre-2025 WH-347, fix that before 9-30-2026.
2. Pull one wage determination and check base plus fringe against what you actually paid that classification last week. If it does not clear, you have an exposure right now.
3. Audit your classifications against work actually performed, not titles.
4. Recompute your fringe credit with administrative costs removed.
5. Fix the time capture so classification rides along with every hour at entry.
