Payroll for Construction Companies
Construction payroll is more complex than most industries. This guide covers certified payroll, prevailing wage, union deductions, job costing labor, and how to keep construction pay runs accurate.
Construction payroll is harder than most industries. Your workers move between job sites, earn different rates on different projects, work under prevailing wage rules on public work, pay union dues and benefit contributions, and every labor hour has to be tracked back to the job it was worked on. Each of those has to be handled separately so you can bill accurately, stay compliant, and see which jobs are profitable.
Construction payroll is built to handle that complexity. It adds certified payroll reporting, prevailing wage calculations, union deductions, and job costing labor to standard payroll. This guide explains what construction payroll involves, how it differs from general payroll, and how to set it up so your pay runs are accurate and your labor costs land on the right jobs. If you are newer to payroll altogether, it helps to start with our guide on how payroll processing works first.
Why Construction Payroll Is Different
Most businesses pay each employee one rate and move on. A construction company pays the same worker different rates on different jobs, reports wages weekly on public projects, deducts union dues and benefit contributions, and tracks every hour back to a specific job. If you only look at your total payroll, you can see what you spent on labor, but you cannot see which jobs ate your margin or whether your certified payroll reports match what you actually paid.
The other difference is compliance. Public work comes with prevailing wage rules and weekly reporting. Union work comes with deductions and remittances. Miss either one and you create liability that can follow you onto the next bid. For a broader look at how payroll compliance works, see our guide on the payroll compliance checklist.
Quick tip. Set up your payroll to track hours by job, by rate, and by classification before you take on your first public project. Retrofitting job costing and prevailing wage tracking onto payroll that was never set up for them is one of the hardest cleanup projects there is, and it is far more expensive than setting it up correctly the first time.
Certified Payroll Reporting
Certified payroll is a weekly report of wages paid on certain public works projects. Each week, you report each employee's name, work classification, hours worked, gross wages, and fringe benefits for the work performed on that project. The report is signed to certify that the wages paid meet the prevailing wage requirements for that project.
The requirement and the exact form vary by jurisdiction and by the funding source of the project. Federal projects typically use a standard form, while state and local projects may use their own. If you work on public projects, confirm with the contracting agency what reporting is required before you start. Missing or late certified payroll reports can put your contract and your ability to bid future work at risk, so build the reporting into your weekly payroll cycle rather than treating it as a separate task.
Prevailing Wage and Davis Bacon
Prevailing wage laws set a minimum pay rate for workers on covered public projects. Federal projects are governed by the Davis Bacon Act, and many states have their own prevailing wage laws for state funded work. The prevailing rate includes both a base wage and a fringe benefit amount, and it is set by job classification, not by employee.
Prevailing wage calculations fall into a few categories, and keeping them separate is what keeps your pay runs and your reports accurate. Here is how to break them down:
| Wage component | What it includes | How to track it |
|---|---|---|
| Base wage | The hourly wage rate set for the classification on the project. | Pay at the prevailing base rate for hours worked on the covered project. |
| Fringe benefits | The fringe portion of the prevailing wage, paid as cash or benefits. | Pay as cash or contribute to a qualifying benefit plan per the rules. |
| Regular rate | The employee's normal hourly rate on private work. | Pay the higher of the regular rate or the prevailing rate for each hour. |
| Overtime | Time and a half for hours over the daily or weekly threshold. | Calculate overtime on the prevailing rate for covered hours. |
| Deductions | Union dues, taxes, and other withholdings from gross pay. | Deduct per the employee's elections and your union agreement. |
| Job costing | Labor cost tagged to the specific job and phase. | Tag every hour by job so labor cost lands on the right project. |
If a worker's regular rate is below the prevailing rate, you pay the prevailing rate for the hours worked on that project. If their regular rate is above it, you pay the regular rate. Track prevailing wage hours separately from regular hours so your certified payroll report shows the right wage for each hour and you can confirm you are meeting the required rate.
Example: Prevailing Wage on a Public Project
Say you run a small framing company with a crew of six. You land a public school project covered by prevailing wage, where the carpenter classification pays $48 per hour in base wages plus $14 per hour in fringe benefits. Your carpenters normally earn $32 per hour on private work. For every hour they work on the school project, you pay $48 per hour in base wages and handle the $14 fringe as cash or as a contribution to a qualifying benefit plan, depending on the rules that apply.
If hours are tracked by job and by rate, your payroll shows the correct prevailing wage for the school hours and the regular rate for any private hours worked that week. Your certified payroll report shows each carpenter's name, classification, hours, and the prevailing wage paid. Without that tracking, you risk underpaying the prevailing rate, filing an inaccurate certified payroll report, or carrying compliance risk onto your next public bid.
Union Deductions and Fringe Benefits
Many construction companies work under union agreements that require specific deductions from each employee's gross pay. Union deductions include dues, initiation fees, and contributions to union administered benefit plans such as pension, health and welfare, and training funds. Deduct the amounts specified by your agreement from each employee's gross pay, and remit them to the union or the benefit funds on the schedule the agreement requires.
Track each deduction by employee and by type so your remittance reports match what the union expects. If union deductions are not remitted on time or in the right amounts, you can create liability under your collective bargaining agreement. Reconcile union deductions every pay period so your remittances stay accurate and your obligations stay current.
Job Costing Labor by Project
Job costing labor means tracking every labor hour back to the specific job or project it was worked on. When you run payroll, tag each employee's hours by job, by phase, and by labor type so the labor cost lands on the right job. When you post payroll to your books, move the labor cost from a general payroll account to the job cost account for each project.
If labor is not job costed, every job looks like it has the same labor cost and you cannot see which jobs are profitable and which are losing money. Job costing is what turns payroll from an expense into a report you can act on, because it shows you whether your contract price covered your actual labor. For a deeper look at how bookkeeping supports that, see our guide on bookkeeping for construction contractors.
Example: Job Costing Labor Across Two Job Sites
Consider a small electrical contractor with a crew of four working across two job sites in the same week. On Monday and Tuesday, the crew works a residential remodel billed at a fixed contract price. On Wednesday through Friday, they work a commercial tenant improvement billed at time and materials. If every hour is tagged by job, your payroll shows $6,400 in labor on the residential job and $9,600 on the commercial job, which means your job cost reports match what you actually spent on each project.
Without job costing, all $16,000 in labor lands in a single payroll expense account and you cannot tell which job ate your margin. When you bill the commercial job, you can only bill the labor you can see, which means untracked labor is unbilled labor. That detail is what turns a busy week into a report you can act on, and it is the earliest sign that a job is losing money.

- Tag every labor hour by job and by phase so labor cost lands on the right project.
- Reconcile union deductions and remit them on the schedule your agreement requires.
- Reconcile payroll tax deposits and confirm filings are submitted on time.
- Post payroll to your books with labor moved from payroll expense to job cost accounts.
- Review job cost reports against contract prices to spot jobs losing margin.

Common Construction Payroll Mistakes
- Not tracking hours by job. If hours are not tagged by job, you cannot job cost labor and every project looks like it has the same cost. Tag every hour by job and by phase so labor cost lands on the right project.
- Paying the regular rate on prevailing wage jobs. If a worker earns below the prevailing rate and you pay their regular rate on a covered project, you underpay the prevailing wage and risk your contract. Apply the prevailing rate to every covered hour.
- Missing certified payroll reports. If certified payroll reports are not filed weekly on covered projects, you create compliance risk that can follow you onto future bids. Build reporting into your weekly payroll cycle.
- Not remitting union deductions on time. Union dues and benefit contributions have to be remitted on the schedule your agreement requires. Late or incorrect remittances create liability under your collective bargaining agreement.
- Lumping all labor into one payroll account. If labor is not moved from payroll expense to job cost accounts, you cannot see which jobs are profitable. Post payroll with labor moved to the right job cost accounts.
- Not tracking multiple pay rates for the same employee. Many construction workers earn different rates on different jobs. If each hour is not tagged by rate, your paycheck does not match the work performed and your reports are wrong.
Getting Started
Construction payroll only works if it is set up for the way a construction company actually works and maintained consistently. If your hours are not tracked by job, your prevailing wage is not calculated correctly, or your certified payroll reports are not filed on time, you cannot see which jobs are profitable and you carry compliance risk onto every public bid. The best next step is a conversation about where your payroll stands today.

Frequently Asked Questions
What makes construction payroll different from regular payroll?
Construction payroll adds certified payroll reporting, prevailing wage calculations, union deductions and fringe benefits, and job costing labor by project to standard payroll. A typical construction company pays workers at different rates on different jobs, reports wages weekly on public projects, deducts union dues and benefit contributions, and tracks every labor hour back to a specific job. Each of those has to be tracked separately so you can bill accurately, stay compliant, and see which jobs are profitable. Without that breakdown, you cannot tell whether your labor costs are covered by your contract price or whether you are carrying compliance risk on public work.
What is certified payroll and when is it required?
Certified payroll is a weekly report of wages paid on certain public works projects, typically those covered by federal or state prevailing wage laws. Each week, you report each employee's name, classification, hours worked, gross wages, and fringe benefits for the work performed on that project. The requirement and the exact form vary by jurisdiction and by the funding source of the project. If you work on public projects, confirm with the contracting agency what reporting is required before you start, because missing or late reports can put your contract and your ability to bid future work at risk.
How does prevailing wage affect construction payroll?
Prevailing wage laws set a minimum pay rate for workers on covered public projects, including both base wages and fringe benefits. If a worker's regular rate is below the prevailing rate, you pay the prevailing rate for the hours worked on that project. If their regular rate is above it, you pay the regular rate. The fringe benefit portion can be paid as cash or contributed to a qualifying benefit plan, depending on the rules that apply. Track prevailing wage hours separately from regular hours so you can report them accurately and confirm you are meeting the required rate.
How do I handle union deductions in construction payroll?
Union deductions include dues, initiation fees, and contributions to union administered benefit plans such as pension, health, and training funds. Deduct the amounts specified by your union agreement from each employee's gross pay, and remit them to the union or the benefit funds on the schedule the agreement requires. Track each deduction by employee and by type so your remittance reports match what the union expects. If union deductions are not remitted on time or in the right amounts, you can create liability under your collective bargaining agreement, so track them carefully and reconcile them every pay period.
How do I job cost labor in construction payroll?
Job costing labor means tracking every labor hour back to the specific job or project it was worked on. When you run payroll, tag each employee's hours by job, by phase, and by labor type so the labor cost lands on the right job. When you post payroll to your books, move the labor cost from a general payroll account to the job cost account for each project. If labor is not job costed, every job looks like it has the same labor cost and you cannot see which jobs are profitable and which are losing money. Track it by job so your job cost reports match what you actually spent.

How should I track multiple pay rates for the same employee?
Many construction workers earn different rates on different jobs, especially when prevailing wage applies. Track each employee's hours by job and by rate so the correct pay applies to each hour. If a worker spends Monday on a private job at their regular rate and Tuesday through Friday on a prevailing wage job at a higher rate, their paycheck has to reflect both rates accurately. Tag every time entry by job and by rate so your payroll calculation matches the work performed and your certified payroll report shows the right wage for each hour.
