If you're doing prevailing wage work, certified payroll isn't optional. Neither is getting it right. Here are the five errors that keep coming up — and what to do about each one.

1. Wrong worker classification A laborer and a carpenter's helper are not the same thing on a wage determination. Neither is an equipment operator. If your foreman is tracking hours without classification codes tied to the actual wage determination, you're guessing every week — and every wrong guess is a liability. Fix it: Build a classification code sheet at project kickoff. Hand it to every foreman before day one.

2. Blowing the fringe benefit math You can offset part of your prevailing wage obligation with health insurance, pension contributions, and vacation pay. But you have to calculate it per hour worked, document it properly, and get the number right. Underclaim and you're paying more than you have to. Overclaim and you're one audit away from a back-wage bill. Fix it: Calculate your per-hour fringe credit before the first payroll run. Keep the plan docs in the project folder.

3. Getting the overtime wrong Davis-Bacon, FLSA, and your state's prevailing wage law all have different overtime rules — and they stack. Federal overtime after 40 hours a week. Davis-Bacon prevailing rates for the first 8 hours a day. Some states add daily OT on top of that. Trying to run all three from memory on a Friday afternoon is how errors happen. Fix it: Write down the overtime rules that apply to each project's jurisdiction before work starts. Check it every week.

4. Claiming fringe credits without the paperwork to back them up You can submit a clean WH-347 every week for two years and still have a problem if the DOL asks for your plan documentation and you can't find it. An insurance card isn't documentation. A pension enrollment form isn't documentation. You need the actual plan docs showing what you contribute per hour. Fix it: Organize fringe documentation at kickoff, not after the audit letter arrives.

5. Late submissions (or just... not submitting) One late week is recoverable. A pattern of missed submissions tells auditors your back-office controls are weak — and that tends to expand the investigation beyond the submission timing into whether workers were actually paid correctly. Fix it: Shared calendar. One named owner per project. Self-report immediately if you miss a deadline.

The honest truth? None of these are people problems. They're process problems. Every single one of them is fixable before your next project starts — no software required.

If you run a construction company, payroll usually doesn’t end when the checks go out. There’s still time entry to review, job costs to sort out, and numbers to line up in accounting.

A lot of that extra work comes from payroll and accounting not really talking to each other.

Most payroll systems handle basic wages fine, but construction adds layers, cost codes, multiple pay rates, certified payroll, union rules.

When those details don’t carry over automatically, teams end up re-entering data or fixing things after the fact. It works, but it’s slow, and small mistakes tend to sneak in.

Over time, those little issues add up. Labor costs don’t always land where they should. Job reports feel slightly off. You don’t notice until a project wraps up tighter than expected.

With a construction payroll and accounting integration, things go smoother. Hours flow into job cost reports. Burden applies automatically. The general ledger updates without someone having to touch it twice. Certified and union jobs are handled as part of the process, not as extra steps.

It doesn’t make payroll exciting, it just makes it easier to trust the numbers you’re looking at.

If you’re thinking about changing payroll systems, it’s worth paying attention to how well it integrates with your accounting software. That connection usually makes a bigger difference than any single feature.

Multi-State Payroll Is Where Construction Payroll Breaks

Managing payroll for a construction company sounds simple—until your crews are working in multiple states at the same time.

One week it’s Texas. Next week it’s California. Then someone crosses into Nevada for a public works job.

Suddenly payroll isn’t “just payroll” anymore.

It’s prevailing wage, union fringes, certified payroll deadlines, and state tax rules that don’t agree with each other.

Why multi-state construction payroll gets complicated fast

Every state brings its own rules:

Different prevailing wage databases and classifications

Union contracts with unique fringe benefit requirements

Apprentice and training fund rules that change by location

State and local tax withholding that depends on where work happens—not just where workers live

Certified payroll reports with strict deadlines and zero tolerance for errors

One mistake can mean back pay, audits, penalties, or losing eligibility for future public works projects.

And spreadsheets? They collapse under that kind of pressure.

Prevailing wage isn’t flexible—and it’s not optional

Prevailing wage rates change by:

State

Trade

Project type

Funding source

Apprentice status

Miss an update or classify a worker incorrectly and the consequences are immediate: back pay liability, audit findings, or contract disqualification.

There’s no room for guesswork here.

Union fringes add another layer

Union payroll isn’t just hourly pay. It includes:

Pension contributions

Healthcare funds

Apprenticeship requirements

Training fund payments

Overtime rules that vary by contract

Now multiply that across several states with different union agreements.

Manual calculations don’t just slow things down—they introduce risk.

Certified payroll depends on upstream accuracy

Certified payroll reports only work if the payroll data behind them is flawless.

If:

Wage classifications are wrong

Fringe calculations are off

Hours are miscategorized

…the report fails. And failed reports trigger audits.

Certified payroll doesn’t forgive small mistakes.

Multi-state taxes make it even messier

Construction workers often live in one state and work in another. Some states tax residents differently than non-residents. Some have reciprocity agreements. Some have rules specific to construction labor.

Tracking all of that manually is how companies end up with tax exposure they never expected.

The difference automation makes

Construction-specific payroll systems are built for this reality.

They:

Pull prevailing wage rates directly from state databases

Apply union fringe rules automatically by contract

Generate certified payroll reports without rework

Track residency and job location for accurate tax withholding

Maintain audit-ready records across every project

What used to take hours becomes repeatable, accurate, and predictable.

Successful construction companies don’t “work harder” at payroll.

They stop trying to force general payroll tools and spreadsheets to handle construction complexity.

They use systems designed for:

Multi-state crews

Public works compliance

Union labor

Certified payroll reporting

And that shift turns payroll from a constant liability into a controlled process.

Yes — federal law requires certified payroll to be submitted every week that covered work is performed on construction projects exceeding $2,000. Under the Davis-Bacon Act and Copeland Act (40 U.S.C. § 3145), contractors and subcontractors must file weekly wage statements and certified payroll reports (Form WH-347 with a signed Statement of Compliance).

Failing to submit these reports can result in withheld funds, contract termination, or debarment for up to three years. Each report documents every worker’s hours, wages, and benefits to prove compliance with prevailing wage laws.

If there’s a week with no covered work, federal law doesn’t require a payroll submission — but many agencies still require a “No Work” statement to maintain continuous records. Always check your contract for specific documentation rules.

Certified payroll keeps workers protected and ensures fair competition among contractors. The process can feel overwhelming, but modern automation makes it easier than ever.

Payroll4Construction streamlines Davis-Bacon compliance by generating accurate WH-347 reports automatically, reducing manual work and errors.

The Benefits of a Construction Payroll Service

Contractors searching for a payroll service shouldn’t outsource their payroll needs to just anyone. It’s most beneficial for construction professionals to outsource their payroll to construction payroll providers. Some other things to consider include:

Integrations with Accounting Systems: Contractors should seek out a payroll for construction company that integrates seamlessly with their current job costing system if they have one. This will help ensure contractors can allocate labor costs accurately to each project, thereby enhancing budgeting and financial planning.

Compliance with Certified Payroll: All federally and publicly funded construction projects demand contractors comply with prevailing wage requirements. A construction-specific payroll provider will understand the intricacies of these requirements and will be able to fulfill them with ease and at no extra cost. This will help contractors to ensure accurate reporting to the Department of Labor (DOL) and maintain compliance with project labor agreements.

Certified payroll is a special weekly payroll report required for contractors working on federally funded construction projects. Here are the key points about certified payroll:

What is Certified Payroll?

Certified payroll is a weekly payroll report that contractors and subcontractors must submit when working on federal construction projects over $2,000. It uses Form WH-347 to certify that workers are being paid the prevailing wage as required by the Davis-Bacon Act.

Check out this post for more information about staying compliant with the Davis Bacon Act of 1931 and certified payroll.

When is Certified Payroll Required?

Certified payroll is mandatory for:

Federally funded construction contracts over $2,000

Contractors and subcontractors on these projects

Various types of construction work, including building, alteration, painting, repair, etc.

Key Requirements For Certified Payroll

To comply with certified payroll rules, contractors must:

Pay workers the prevailing wage weekly

Complete Form WH-347 with detailed employee information

Cost efficiency: Accurate labor cost tracking and integration with accounting systems.

When selecting a payroll service, look for one that specializes in construction industry needs, offers integration with popular software, and provides expert support. Construction companies can focus on core business activities and drive growth by streamlining payroll processes.

In a construction company, you have thousands of moving parts to keep track of at all times — literally and figuratively. 

Besides maintaining and tracking equipment, bidding, hiring, and managing job sites, construction payroll alone can give you plenty to navigate. Just look at state taxes! And as your business expands across state borders — or as you consider expanding across state borders — understanding how tax regulations can vary from state to state can be, well, taxing.

Your business relationship (or “nexus”) to state tax jurisdictions and the amount owed to them (or “apportionment”) is determined by the overlapping state, federal and other mandates. 

On the one hand, this can lead to contractors being out of compliance with payroll tax obligations — just as often, it can mean paying more than required to additional tax authorities. But don’t let that hold you back from taking on out-of-state jobs. 

The key to success is recognizing some of these common pitfalls and getting help from tax, legal, and construction payroll experts to ensure you’re navigating these issues correctly.

Staying Current is Rule #1

The first key to thriving with multi state payroll is to stay current. Working in two to four states on the same payroll is not unusual for many contractors. 

While winning jobs out of state is good, it can quickly complicate things. The most challenging aspect of working in multiple states is that each jurisdiction has different rules and regulations for payroll and taxes. 

Furthermore, none of them are written in stone, and they can change at any time. When considering the several states that hold potential projects for your company, staying current can be a serious undertaking.

As an example, regulations on recordkeeping can vary from state to state. While some states have no recordkeeping requirements, most require that employers retain records for a minimum of three years. 

Be sure to learn these requirements before you begin work in a new state — especially if your home state doesn’t have such requirements. 

Penalties and fines will also differ from state to state, including civil penalties, misdemeanor convictions, jail time, and fines from $100 to $10,000.

Additionally, some states hold reciprocity agreements with each other. Reciprocity between two states is an agreement allowing workers to pay taxes only to the state where they live. When this article was written, Ohio and Pennsylvania have a reciprocity agreement in which Ohio residents who work in Pennsylvania don’t have to pay Pennsylvania taxes. 

But these laws change. Pennsylvania and New Jersey had a reciprocity agreement that lasted almost 40 years but ended on January 1, 2017. Suddenly, companies and workers had to pay taxes to both states.

Steer Clear of Double Taxation

Besides keeping up with different regulations, double taxation can also arise. This occurs when an employee pays taxes twice on the same income — once for State A and once for State B, doubling the income tax they’re paying. 

Avoiding double taxation requires time and attention to detail. Employers must ensure that work is allocated to the correct state on timecards. Employees should carefully check paystubs to verify that their work is being reported to the state where the job was performed.

At tax time, the employee must file a resident state income tax return to report all income, including income earned out of state. They’ll also file a non-resident state income tax return to report only the income earned in that state. 

The resident state will typically give a tax credit for taxes paid on out-of-state work. As a result, the employee will pay taxes only once on their income.

Avoiding Overpayment in Unemployment

Along the same lines as double taxation, many contractors unknowingly pay unemployment insurance to the additional states in which they work while only needing to pay their base state. To determine where to pay unemployment insurance, four factors set by the U.S. Department of Labor should be considered.

1. Are the services localized? Localized means that the work is performed entirely in one state or that the work performed in additional states is incidental — meaning temporary. For example, a Florida worker receives a request to complete a job in Georgia. The job in Georgia is completed in a few months, and he returns to Florida on his original job. 

In this case, work is localized to Florida since the work in Georgia was temporary. When work is localized, state unemployment tax (SUTA or SUI) will be paid to that state. If not, consider the following factors.

2. Does a base of operations exist for the employee? When services aren’t localized in one state, determine if there’s a base of operations for that employee. A base of operations can be an office or a place where employees get instructions, receive or repair supplies and equipment, designate mail service, or manage and maintain business records. SUTA or SUI goes to the state where a base of operations is located.

3. Is there a place of direction or control? You might not have a base of operations, but if there’s a location from which you direct or control an employee, taxes for all work performed will be reported to that state.

4. What’s the employee’s state of residence? Consider the state where the employee resides if there’s no localization, no base of operations, and no center of direction or control.

Once these four factors have been considered, you should have narrowed down the state to which SUTA or SUI will be paid for that employee. 

Unemployment should typically be paid to only one state per employee. Again, it is always best to consult your payroll or legal expert to confirm your thought process and decision.

Take Time Now to Avoid Issues Later: A Few Best Practices

Much like many other aspects of business — and life — what can help avoid issues with state taxes is being prepared and detailed from the beginning.  Once a job is awarded, thoroughly research the state tax rules and regulations.

Additionally, the more detailed your timecards are, the better. This includes cost codes, trades, and hours worked, broken out by each job. It’s also extremely important to make sure you have job and employee records up to date at all times, especially home addresses. This takes more time upfront but will pay off greatly as you file taxes.

Finally, ensure you have numerous reports available and processes in place to review your payroll details before payroll is processed. Running timecards and proofing reports may help you catch mistakes and avoid issues in the future.

Work With A Company That Knows How To Handle Multi-State Taxes

Having reviewed a handful of multi-state tax issues here, we’ve only scratched the surface regarding working in multiple states. However, contractors don’t have to — and shouldn’t — go it alone. 

Taxation and legal counsel are irreplaceable. Construction-specific CPAs are a must-have for contractors of any size, and along with their professional guidance, a construction-specific payroll service can execute tax-compliant processing without headaches.
