A prevailing wage form is mandatory documentation that proves that contractors on government-funded construction projects paid workers the federally or state-mandated wage rates, including detailed records of hours, classifications, and fringe benefits for each employee. Contractors must submit these certified payroll forms weekly to avoid penalties, maintain eligibility for future public work, and pass Department of Labor audits. Fortunately, automation tools can significantly reduce the administrative burden and compliance risks of manual tracking.
Government-funded construction projects require you to submit prevailing wage forms. Miss a detail, and you're looking at thousands in penalties, contract disputes, or losing your eligibility for future public work. Most contractors find these forms frustrating: Tracking multiple pay rates, fringe benefits, and worker classifications across different jurisdictions creates real headaches.
This guide covers which forms you need, how to fill them correctly, and what records you must keep for audits. If you're filing certified payroll for the first time or managing compliance across job sites, you'll learn how to avoid expensive mistakes and keep projects on schedule.
Prevailing wage requirements determine how much you pay your workers, what documentation you must maintain, and the penalties you face for getting things wrong. The prevailing wage form serves as your official record that proves compliance with federal or state-mandated wage standards. Every contractor working on covered projects needs to know exactly what these forms require and how they protect both workers and your business.
Prevailing wages represent the hourly wages, benefits, and overtime paid to the majority of workers in a specific occupation within a particular geographic area. The U.S. Department of Labor defines a prevailing wage as the average wage paid to similarly employed workers in the area of intended employment. This is typically the market rate for skilled trades in your region, which often aligns with union scale wages (whether your workers are union members or not).
The Davis-Bacon Act established this framework in 1931, requiring contractors on federal construction projects exceeding $2,000 to pay locally prevailing wages. In addition to the federal requirements, more than 30 states have enacted their own prevailing wage laws with varying thresholds and specific rules. California's threshold differs from Texas's requirements, and Nevada's recent survey updates will affect how you bid projects in that state.
Your prevailing wage form captures all relevant data: worker classifications, actual hours worked, wage rates paid, fringe benefits provided, and any deductions taken. It acts as proof of compliance that auditors will scrutinize during investigations. Proper certified payroll documentation is essential when managing these complex reporting requirements.
The prevailing wage form isn't just paperwork; it's a legal shield proving that you paid workers correctly, which makes it your ticket to future government contracts.
Both prime contractors and subcontractors must file prevailing wage forms on covered projects. If you're the general contractor awarded a federally funded highway project, you file. If you're the electrical subcontractor hired by that general, you also file separately for your workers. The responsibility flows through every tier of the project structure, which means coordination among all parties becomes critical for maintaining compliance across the entire job site.

Federal projects use different documentation than state-funded work, and each jurisdiction maintains its own reporting standards. The documentation requirements change based on funding sources, project types, and location, and mixing up forms creates compliance gaps that cost you time and money.
Federal construction projects exceeding $2,000 require Form WH-347 for certified payroll reporting under the Davis-Bacon Act. According to Hammr, this prevailing wage form must include worker names, Social Security numbers, job classifications, daily hours worked, hourly wage rates, fringe benefits, gross wages, deductions, and net wages paid. You submit this weekly for every pay period where work occurred on the covered project.
The companion Form WH-348 serves as a compliance statement certifying the accuracy of WH-347 payroll reports. Both prime contractors and subcontractors must file these prevailing wage forms separately. Bear in mind that the Department of Labor updated the WH-347 format in January 2025 with revised fields and layout changes.
Beyond construction, over 60 federal statutes now incorporate Davis-Bacon requirements, extending to programs administered by the Department of Transportation, HUD, EPA, and Department of Energy loan guarantees for renewable energy projects. Each agency may have supplemental reporting requirements beyond the standard WH-347, so review your contract specifications carefully before your first payroll cycle.
State prevailing wage laws create a patchwork of different forms and submission procedures. California, New York, Pennsylvania, Virginia, and Nevada each maintain distinct prevailing wage form requirements with varying thresholds, deadlines, and penalties. Virginia's Department of Labor and Industry requires contractors working on state-funded projects valued at $250,000 or more to submit a DOLI Pay Scale Certification and weekly payroll records. Pennsylvania uses its own appeal and classification request forms administered through the Prevailing Wage Appeals Board. Nevada recently released updated wage determinations for 2025-2027 that affect how you classify workers and calculate rates for state projects.
State prevailing wage thresholds range from $2,000 in some jurisdictions to $250,000 in others, so verify your specific requirements before bidding on any public project.
Some states reference federal Davis-Bacon determinations, while others conduct independent wage surveys. This means you might face different wage rates for the same trade classification depending on whether your project receives federal or state funding. Localities may add their own ordinances requiring prevailing wages on city or county projects, creating a third layer of compliance. Always verify which jurisdiction's prevailing wage forms apply when multiple funding sources contribute to a single project. Accurate job costing is essential when tracking these varying wage requirements across different projects and funding sources.
Certified payroll differs fundamentally from your regular payroll processing. Standard payroll tracks gross pay, taxes, and deductions for your business operations. Certified payroll, submitted through prevailing wage forms, proves you paid government-mandated rates with specific worker classifications tied to physical job sites. You're certifying under penalty of perjury that every entry is accurate, which carries legal weight far beyond routine payroll reports sent to your accountant.
Here's what separates certified payroll from your standard payroll processes, and why understanding these distinctions matters for compliance:
Your standard payroll system likely can't generate compliant prevailing wage forms without significant modifications. For this reason, most contractors maintain parallel tracking systems: one for regular business payroll and another specifically for certified payroll on covered projects. This sort of duplication increases administrative burden and creates reconciliation challenges when the same workers split time between prevailing-wage and non-prevailing-wage projects during a single pay period.

The accuracy of the prevailing wage form can determine whether you pass an audit or face penalties that derail your business. Each field connects directly to federal or state wage determinations, worker classifications, and fringe benefit calculations.
Before you start on the prevailing wage form, collect complete employee data for every worker who performed labor on the covered project during the pay period. You need full legal names exactly as they appear on Social Security cards, not nicknames or shortened versions. Social Security numbers are mandatory on federal WH-347 forms and most state prevailing wage forms. Document each worker's home address, including city, state, and ZIP code. This information verifies residency status and helps agencies track workforce demographics on public projects.
Job classifications require precision because they specify which wage determination applies to each worker. Don't use general titles like “laborer" when the wage determination specifies “unskilled laborer," “semi-skilled laborer," or “skilled laborer" as separate classifications with different rates. Cornell University's Center for Applied Research on Work explains that prevailing wage laws establish minimum labor standards by setting wage and benefit floors based on comparable local work done on similar projects. Review the wage determination attached to your contract and match each worker's actual duties to the appropriate classification. If someone performs multiple trades during a single shift, track those hours separately and apply the correct rate for each classification.
Matching workers to the correct job classification on your prevailing wage form requires being clear about what work they actually performed on the covered project according to the contract's wage determination.
Each prevailing wage form requires you to report base hourly rates and fringe benefits separately. The wage determination specifies both components; e.g., $35.50 per hour base rate plus $18.25 per hour in fringe benefits.
You can satisfy fringe benefit obligations through actual contributions to bona fide benefit plans, cash payments to workers, or a combination of both methods. Track daily and weekly hours worked, separating straight time from overtime. Overtime on prevailing wage projects follows both federal Fair Labor Standards Act requirements and prevailing wage overtime calculations, which can differ from your standard payroll practices.
Calculate gross wages by multiplying hours in each classification by the applicable prevailing wage rate. Document all deductions itemized on the form: federal withholding, state withholding, Social Security, Medicare, and any authorized voluntary deductions. Net wages equal gross wages minus total deductions.
Every dollar must reconcile between your certified payroll records and your actual payroll system. Fringe benefit contributions require separate documentation showing deposits made to health and welfare plans, pension funds, training programs, or other qualifying benefits that meet Department of Labor standards for bona fide plans. Job costing helps you track these labor expenses across projects and ensure that your wage calculations align with your financial records.
Agencies compare your prevailing wage forms against time tracking systems, gate logs, and superintendent daily reports. Discrepancies (e.g., rounding hours to the nearest half day instead of recording actual time worked) suggest that you're manipulating records to reduce labor costs. Using the wrong wage determination because you didn't check for updates after contract award happens frequently; wage determinations can be modified during the course of multi-year projects, and you're responsible for applying current rates even if your original bid used outdated information.
Failing to break out apprentice ratios properly triggers scrutiny. Prevailing wage laws typically limit the ratio of apprentices to journeyworkers on each project. If your forms show more apprentices than the allowed ratio permits, auditors will reclassify them as journeyworkers and calculate back wages at the higher rate.
Finally, missing signatures on the compliance statement portion of your prevailing wage form invalidates the entire submission. The person signing certifies accuracy under penalty of perjury, so unsigned forms mean you haven't certified anything. Agencies treat that as a non-submission requiring corrective action (potentially with penalties).
Supporting documentation transforms your prevailing wage form from a claim into proof. Maintain daily time records showing each worker's arrival time, departure time, lunch breaks, and tasks performed. These records must match the hours reported on your forms. Keep copies of fringe benefit plan documents, trust agreements, and contribution receipts proving you actually funded the benefits claimed on the prevailing wage form. Also store worker classification justifications explaining why you assigned each employee to specific wage determination categories; this documentation becomes critical when auditors question your classifications.
Retain payroll registers, cancelled checks, electronic payment confirmations, and bank statements showing that you paid workers the amounts reported on prevailing wage forms. Most jurisdictions require you to keep these records for three to five years after project completion, but some federal programs extend retention requirements to seven years. Organize documentation by project and pay period, so you can quickly produce complete records during investigations. Missing documentation forces auditors to assume that violations occurred, shifting the burden to you to prove compliance without evidence.
Manual prevailing wage form processing eats up hours that your team should spend on billable work. Tracking multiple wage determinations, calculating complex fringe benefits, and reconciling certified payroll with regular payroll systems forces most contractors to maintain duplicate spreadsheets. This duplication increases error rates and exposes you to audit risk.
Technology solutions fix these problems by automating data flows between your existing systems, eliminating redundant entry, and generating compliant prevailing wage forms without manual intervention.
Preparing prevailing wage forms manually creates multiple points where things go wrong. Your payroll administrator pulls time data from one system, wage rates from paper determinations, and fringe benefit calculations from spreadsheets. They transfer this information into the WH-347 template or state-specific prevailing wage form, manually typing each worker's name, classification, hours, and rates. A single transposition error will invalidate the entire submission and trigger follow-up questions from contracting agencies.
Reconciliation between your certified payroll records and actual payroll checks means comparing two separate datasets that should match but frequently don't. Workers who split time between prevailing wage projects and private work need dual tracking throughout the pay period. The Onsi Group notes that contractors often remain unaware that they're noncompliant until Department of Labor investigations begin. At that point, of course, correcting records becomes significantly more difficult and expensive.
Version control becomes a nightmare when wage determinations change mid-project. You might have workers performing identical tasks under three different wage determinations depending on when they started. Your spreadsheets multiply, tracking becomes fragmented, and audit trails disappear. When investigators request documentation showing why you paid specific rates on particular dates, reconstructing that decision-making process from scattered files takes days of administrative work. This pulls resources away from active projects when you need them most.
Manual prevailing wage form processing doesn't just waste time. It creates compliance gaps that investigators exploit during audits, turning administrative inefficiency into legal liability.
Automation eliminates duplicate data entry by connecting your time tracking, payroll, and accounting systems into unified workflows. Workers clock in once, and that time data flows automatically to both regular payroll and certified payroll calculations. The system applies appropriate wage determinations based on project codes, calculates fringe benefits according to your plan structures, and generates compliant prevailing wage forms without manual intervention. Updates to wage determinations propagate across all active projects instantly, ensuring that every worker receives correct rates from the effective date forward.
Integration between payroll providers and project management platforms creates a single source of truth for labor costs. When your field supervisor approves timesheets in the project management system, those hours sync directly to payroll processing with job cost codes intact. Prevailing wage forms populate automatically using verified data rather than manually transferred information subject to human error. The system flags discrepancies (e.g., workers clocked to projects without wage determinations, classifications missing from your master list, or fringe benefit calculations that don't match plan documents) before you submit forms to contracting agencies.
Dapt's Project Profitability Platform connects your existing systems, including payroll providers like Paychex, Paycor, and ADP; time tracking tools like QuickBooks Time; project management platforms like JobTread; and accounting software like QuickBooks and Sage. This eliminates the data silos that create prevailing wage form headaches. Dapt’s intelligent SYNCHRONIZATION Engine maps labor hours, pay rates, and benefits to specific jobs automatically, handling complex labor rules, including multi-jurisdictional prevailing wage requirements, without manual configuration.
The platform maintains audit-ready records that meet Department of Labor requirements for certified payroll documentation. Every prevailing wage form generates complete backup information showing time entries, wage determination applications, fringe benefit calculations, and approval workflows. When investigators request documentation, you can produce complete records instantly rather than reconstructing information from scattered spreadsheets. The system tracks changes to wage determinations, documents why specific rates applied to particular workers on given dates, and maintains version history that proves compliance throughout the project lifecycle.
The differences between manual and automated approaches become clear when you compare them side by side. Here's how each method handles critical compliance processes:
Real-time visibility into project labor costs helps you identify issues before they become compliance problems. If workers are clocked to projects without proper wage determinations assigned, the system alerts you immediately rather than requiring you to discover the gap during form preparation. When fringe benefit contributions don't align with certified payroll calculations, you receive notifications that let you correct the discrepancy before submitting prevailing wage forms to contracting agencies. This approach prevents the reactive scrambling that characterizes manual compliance management.
If you're managing multiple prevailing wage projects across different jurisdictions and finding that manual processes create bottlenecks that delay billings and increase administrative costs, contact us to see how automation eliminates duplicate work while maintaining the compliance documentation that protects your eligibility for future government contracts.
Accurate prevailing wage forms protect your ability to bid on future government projects and help you avoid penalties that cut into profits. Getting worker classifications right, calculating fringe benefits correctly, and maintaining complete documentation are what separate contractors who sail through audits from those who face enforcement actions.
When you handle these tasks manually, mistakes happen more often and your team spends hours reconciling spreadsheets instead of managing actual project work. When you connect your time tracking, payroll, and accounting systems, you eliminate duplicate data entry and create audit-ready records that meet Department of Labor requirements. Take a look at how you currently handle prevailing wage forms, find the spots where manual work creates compliance risks, and put solutions in place that move data between systems automatically before you start your next government-funded project.
Check your contract documents for the attached wage determination, which is typically specified at the time of bid or contract award. If your project receives federal funding, verify the determination on the Department of Labor's website, and for state projects, consult your state labor department's prevailing wage division to ensure that you're using the current rates.
While cash payments aren't explicitly prohibited, you must maintain the same detailed documentation required for any other payment method, including receipts signed by workers and complete records that match your prevailing wage form submissions. Most auditors view cash payments with heightened scrutiny, so electronic payments create cleaner audit trails and reduce compliance risk.
Contact the contracting agency immediately to file an amended certified payroll report with corrections clearly noted and an explanation of the error. Voluntary disclosure and prompt correction typically result in more favorable outcomes than errors discovered during audits, though you may still owe back wages if workers were underpaid.
Yes. You must track hours separately and only report the time actually worked on the covered government project in your certified payroll submissions. Your internal payroll system will show the worker's full weekly hours, but the prevailing wage form should reflect only the hours, wages, and fringe benefits attributable to the public project.
Initial document requests typically give you 10-15 business days to respond, and the full investigation can take several months depending on the complexity of your projects and the number of potential violations identified. Well-organized contractors with complete documentation and automated systems often resolve audits faster than those reconstructing records from manual spreadsheets.
