Construction payroll is a compliance function, not just a payroll function. Standard payroll software calculates wages and files taxes. Construction payroll adds more: prevailing wage calculations by trade, weekly certified payroll reports, union fringe tracking and job costing integration. Specifically, one wrong worker classification triggers back wages, civil penalties up to $13,508 and potential debarment from government contracts. This hub covers every dimension: why construction payroll is complex, what the law requires, which software handles it and how to stay compliant.

📌 What Is Construction Payroll?
Construction payroll covers wages, taxes and — on federal projects — prevailing wages by trade classification and weekly certified payroll reports using Form WH-347. Specifically, it is more complex because workers earn different rates based on trade, location and project type. Federal law also mandates specific reporting formats and wage minimums on covered projects. Consequently, standard payroll software is not sufficient for construction contractors.
Loreto Barrionuevo's Take — Why Construction Payroll Is a Category of Its Own
The pattern is consistent across contractor sizes. Specifically, companies that get into compliance trouble are not cutting corners intentionally. Specifically, they use office payroll systems — platforms with no concept of prevailing wage tables, union fringe calculations or certified payroll formats. Consequently, the payroll runs without errors internally, but fails compliance externally because the reporting infrastructure simply does not exist.
The good news is that construction-specific payroll software has matured significantly. Specifically, platforms like Miter, eBacon and Payroll4Construction now automate WH-347 generation and apply prevailing wage rates by county and trade. Labor costs push to job costing in a single workflow. Furthermore, the ROI is straightforward: manual certified payroll preparation takes 6–8 hours per week per project. Automation reduces that to under one hour. For a contractor running three federal projects simultaneously, that is a full-time payroll position replaced by software.

See outsourcing options →Why Construction Payroll Is More Complex Than Standard Payroll
Standard payroll has one variable: the right gross pay per employee per pay period. Construction payroll adds four major layers that standard platforms cannot handle.
📋 Prevailing Wage
On federal and federally-assisted projects, every trade classification has a DOL-determined minimum wage rate specific to the county where work is performed. Specifically, a carpenter in Los Angeles County and a carpenter in rural Ohio earn different prevailing wages on the same federal contract. Furthermore, rates update when DOL publishes new wage determinations — contractors must apply updated rates retroactively if a change occurs mid-project.
🔨 Union Payroll
Union contractors must apply collective bargaining agreement rates, fringe packages and dues deductions for every covered worker. Specifically, a single project may involve multiple unions — each with different overtime rules, fringe contribution amounts and remittance schedules. Additionally, reciprocity agreements between union locals affect which rates apply when workers travel between jurisdictions.
💰 Job Costing
Every labor dollar in construction must be allocated to a specific project, phase and cost code for accurate job profitability tracking. Specifically, payroll data must flow into your accounting system broken down by worker, cost code and day — not as a lump sum. Consequently, when payroll and job costing are disconnected, labor margins become invisible and project profitability estimates become unreliable.
🌎 Multi-State & Multi-Rate
Construction workers routinely cross state lines in the same week, triggering different state tax withholding, workers' comp rates and unemployment insurance rules simultaneously. Furthermore, a worker doing electrical and general labour on the same day needs two different prevailing wage rates on one timesheet. Standard platforms cannot handle this. Standard payroll platforms cannot handle this.
Davis-Bacon — The Federal Compliance Baseline
Specifically, any federal or federally-assisted construction contract exceeding $2,000 triggers Davis-Bacon. Notably, there is no minimum company size exemption. Specifically, this covers HUD-funded housing, federal highway projects, airport construction and school buildings using federal grants. Over 70+ Related Acts extend coverage to $217+ billion in annual construction spending.

⚠️ 2026 Davis-Bacon Key Facts
- Threshold: Federal contracts over $2,000 for construction, alteration or repair.
- Certified payroll: Form WH-347 submitted weekly — even during work stoppages.
- 2024 Rule change: DOL lowered the prevailing wage threshold from 50% to 30%, resulting in higher rates in 85% of surveyed areas. Verify current rates at SAM.gov before bidding.
- Records retention: Payroll records kept for at least 3 years after project completion.
- Subcontractor liability: Prime contractors are responsible for every sub's certified payroll compliance on the project.

Construction Payroll Compliance — What's Actually at Stake
The DOL's Wage and Hour Division recovered $322 million in back wages across all labor law enforcement in fiscal year 2024. Specifically, construction accounts for a significant share. However, most violations result from systems problems — not intentional wage theft. Consequently, the three most common failure points are worker misclassification, incorrect or missing WH-347 submissions and fringe benefit miscalculation.
Consequently, the consequences compound: back wages for all affected workers, civil penalties per violation, contract payment withholding and up to 3 years debarment. Notably, contractors who conduct quarterly payroll self-audits reduce compliance violations by 75% and avoid the average $45,000 cost of a DOL investigation.

Construction Payroll Software — What It Must Do
Standard payroll platforms fail construction contractors on the features that matter most. Specifically, here is what construction-specific software must handle that Gusto, QuickBooks or Patriot cannot:
Miter
Best for: small–mid contractorsBuilt specifically for construction. Specifically, Miter generates WH-347 reports and 10+ state-specific certified payroll formats natively. It handles prevailing wage tables by county and trade, supports union CBA automation and pushes burdened labor costs to job costing in real time. Furthermore, payroll runs in next-day direct deposit at no additional cost.
✅ Choose if: federal projects, union crews, QuickBooks integration needed ❌ Skip if: no government work, very small crew (under 10)eBacon
Best for: compliance-first contractorsSpecifically designed for Davis-Bacon and prevailing wage environments. eBacon automates WH-347 generation, maintains live DOL wage determination tables and handles fringe benefit calculations in the required DOL format. Additionally, it supports electronic submission to state portals and manages subcontractor certified payroll collection — the biggest bottleneck for prime contractors.
✅ Choose if: heavy federal work, multiple subs to manage, strict compliance requirements ❌ Skip if: private work only, no prevailing wage obligationsPayroll4Construction
Best for: union contractors, large crewsFull-service payroll built exclusively for construction. Specifically, it handles multiple CBAs, union fringe automation, home-and-away union logic and generates 40+ construction-specific reports including all certified payroll formats. Furthermore, it integrates with FOUNDATION accounting software — widely used by mid-size to large contractors.
✅ Choose if: union-heavy workforce, multiple CBAs, FOUNDATION accounting ❌ Skip if: non-union only, need modern self-service UIQuickBooks Payroll + Add-ons
Best for: small residential contractorsQuickBooks Online does not natively support certified payroll — however, QuickBooks Desktop with the right setup or third-party add-ons can generate WH-347 reports. Consequently, it works for small residential contractors who occasionally touch government work but is not viable for contractors with regular Davis-Bacon obligations. Notably, the manual overhead of maintaining prevailing wage tables in QuickBooks defeats the purpose of automation.
✅ Choose if: private work, already in QBO ecosystem, minimal federal projects ❌ Skip if: regular Davis-Bacon work, union crews, multi-state operations→ Full side-by-side comparison with pricing: Best Construction Payroll Software 2026.

How to Choose — 4 Questions That Narrow It Down
🏗️ Federal or private projects?
Specifically, Davis-Bacon only applies to federal and federally-assisted contracts. If all your work is private, standard payroll software may be sufficient. However, if any project involves federal funding, you need native certified payroll capability from day one — not a workaround or manual export process.
🔨 Union or open shop?
Union contractors need software that handles multiple CBAs, automatic fringe calculations and union remittance reporting. Notably, this is not a feature most platforms offer well — specifically Miter and Payroll4Construction are the strongest options for union-heavy workforces. Open-shop contractors have more flexibility in software choice.
📊 How important is job costing?
Specifically, if project profitability matters, payroll must push fully burdened labor costs to accounting automatically — not via manual export. Consequently, the integration between your payroll platform and your construction accounting system is as important as the payroll features themselves.
🌍 Single state or multi-state?
Furthermore, multi-state operations require software that handles different state income tax withholding, workers' comp rates and unemployment insurance rules by location. Additionally, working across state lines on federal projects can mean both federal and state prevailing wage rules apply simultaneously. Very few platforms handle this cleanly.
Frequently Asked Questions — Construction Payroll
What is certified payroll in construction?
Certified payroll is the weekly submission of Form WH-347 to the contracting agency on Davis-Bacon covered projects. Specifically, each submission documents every worker's name, Social Security number, trade classification, hours worked per day, gross wages, fringe benefits and deductions. The form becomes certified when the contractor signs a Statement of Compliance — making the responsible party legally accountable for accuracy. Late or incomplete submissions trigger penalties of $1,000–$10,000 per violation. See our full certified payroll guide for step-by-step instructions.
Do construction companies need special payroll software?
For private work only — no, standard platforms are sufficient. Standard payroll platforms handle wages, taxes and direct deposit adequately. However, for contractors working on federal or federally-assisted projects, construction-specific software is effectively required. Specifically, generating WH-347 certified payroll reports manually takes 6–8 hours per week per project. Furthermore, maintaining prevailing wage tables by county and trade without automated software creates compounding error risk across every pay cycle. The compliance risk of using a standard platform on federal work is not worth the cost savings.
Can I use QuickBooks for construction payroll?
For private, non-union work: yes. QuickBooks Payroll handles wages, taxes and job costing integration well for small contractors. However, for Davis-Bacon projects, QuickBooks Online does not natively generate WH-347 certified payroll reports. Specifically, QuickBooks Desktop with specific setup or third-party add-ons can produce the reports, but the manual overhead involved largely eliminates the automation benefit. Consequently, contractors with regular federal work should use a construction-specific platform like Miter or eBacon alongside or instead of QuickBooks. See our construction payroll software comparison for alternatives.
What is prevailing wage and who determines it?
Prevailing wage is the minimum hourly rate — including fringe benefits — that contractors must pay workers on federal and federally-assisted construction projects. Specifically, the Department of Labor determines prevailing wages for each trade classification in each county by surveying local wage rates. Consequently, prevailing wages vary significantly by location — a carpenter's prevailing wage in Manhattan is far higher than in a rural county. Contractors look up applicable rates for their project at SAM.gov using the wage determination attached to their federal contract.
What happens if a contractor fails Davis-Bacon compliance?
Consequences escalate based on severity. Specifically, initial violations mean back wages — the difference between what workers were paid and the required prevailing wage for every covered hour. Additionally, civil penalties of up to $13,508 per willful or repeated violation apply in 2026. Furthermore, the contracting agency can withhold contract payments pending resolution. Serious cases result in debarment from all federal contracts for up to three years and criminal referral for willful violations. Notably, prime contractors are liable for their subcontractors' violations — not just their own payroll. See our construction compliance guide for how to audit your current process.
