What is payroll processing? Guide for construction companies

Payroll processing calculates employee earnings and deductions so a company can pay its employees on time and accurately. In construction, the process also connects labor costs to individual jobs and accounts for the wage requirements that apply to the work. Different pay rates and benefit obligations often complicate those calculations, and small omissions can leave employees underpaid or make a construction project appear more profitable than it is.

This guide explains what payroll processing is and how it works in construction, from recording hours to issuing paychecks. It also covers the laws employers need to follow and various options for managing payroll.

What is payroll processing, and what makes it more complex in construction?

Payroll processing uses work records and pay rates to calculate employee earnings, then subtracts taxes and other deductions to determine take-home or net pay. Employers issue payments and handle the associated tax payments and reporting.

In construction, those calculations can involve different rules within the same timesheet. A carpenter might earn a standard rate of $25 per hour on a private commercial project early in the week. Later in the week, they might switch to a government-funded school project where prevailing wage laws mandate a $38 base plus $10 in hourly fringe benefits.

The following factors add complexity:

• Job and cost-code tracking: Payroll distributes worker earnings and employer costs (like payroll taxes and insurance) across the projects and activities where the hours were worked. Cost codes separate specific tasks on a jobsite, like tracking framing versus electrical rough-in on a residential complex. Tying labor directly to these codes allows contractors to monitor project budgets in real time, analyze true job profitability, and build more accurate estimates for future bids.
• Multiple pay rates: Employees may earn different rates depending on the project or work classification. They might get a higher government-mandated prevailing wage on a public bridge project compared to a standard commercial site, or a temporary bump when moving from general labor to operating heavy machinery. Payroll needs to apply each rate to the corresponding hours worked.
• Overtime calculations: Hours across jobs generally count toward the same weekly overtime threshold. When an employee works at two different pay rates in the same week, payroll must use a weighted-average calculation. Contractors can instead pay overtime at the rate in effect for those hours, but only under an agreement reached with the employee before the work is performed.
• Union agreements: Applicable collective bargaining agreements (CBAs) add specific wage and fringe requirements like mandatory hourly contributions to local union health, pension, and training funds. Additionally, payroll teams must automatically withhold worker-side union dues and assessments from paychecks and remit those funds alongside employer contributions to the appropriate union locals.
• Workers’ compensation classifications: Insurance reporting may require wages and hours to be split strictly by the type of work performed. This is because a roofer carries a higher workers’ comp insurance rate than a finish carpenter. Payroll records must cleanly separate these classifications to prevent costly audit adjustments or overpaying premiums.

6 key steps in the process of payroll system

Construction payroll follows six steps, with job-specific information feeding each calculation.

1. Time tracking and approval

Each time entry identifies the project and cost code, along with the employee’s work classification. Field supervisors verify these entries before payroll runs to ensure the accuracy of further payroll processing. For example, if a worker spent four hours pouring concrete as a laborer and four hours operating a forklift, their timesheet must cleanly reflect the split rather than lumping everything under a single rate.

2. Pay rate determination

Payroll teams confirm the correct rate for each entry, checking any prevailing wage requirements or union dues. They also establish the fringe benefits owed and any specialized overtime rules that apply.

3. Gross pay calculation

Payroll calculates gross pay from approved hours and applicable rates, factoring in any blended overtime or additional compensation owed. This step also requires auditing allowances, like verifying that travel per diem meets IRS accountable plan rules to remain tax-free rather than acting as a disguised taxable wage bonus.

4. Tax withholding and deductions

Payroll subtracts federal, state, and local income taxes, along with standard Federal Insurance Contributions Act (FICA) withholdings. In construction, this step also integrates complex, ongoing deductions like union dues check-offs or court-ordered child support garnishments. The remaining amount is the employee’s net pay.

5. Payment and labor cost allocation

Contractors pay employees via ACH, check, cash, or pay card by the mandated payday. Simultaneously, backend accounting entries break down gross pay, taxes, and burdens like workers’ comp and employer payroll taxes, allocating those labor dollars to specific job codes.

6. Reporting and record retention

Federal filings include quarterly Form 941 and annual Form 940. Employers also issue Form W-2. For Davis-Bacon or state prevailing wage projects, payroll must generate and submit weekly certified payroll reports with a signed Statement of Compliance.

Federal rules require employers to save at least three years of payroll records and four years of employment tax records. Some state laws may require longer retention. For example, New York requires at least six years of payroll records.

Payroll laws and requirements construction companies must follow

Federal laws establish a baseline for construction payroll obligations, while state laws and project requirements can add further rules contractors need to follow.

Fair Labor Standards Act (FLSA)

The FLSA requires minimum wage and overtime pay for covered, nonexempt employees. Federal overtime usually applies after 40 hours worked in a workweek, including hours across multiple jobsites for the same employer. Accurate time records help contractors capture all compensable hours, like qualifying travel time when a crew member hauls equipment from a contractor’s shop to a remote jobsite in the morning.

Federal Insurance Contributions Act (FICA)

FICA covers Social Security and Medicare taxes. Employers generally withhold the employee’s share and pay their own matching share. Social Security tax applies to the first $184,500 of an employee’s annual taxable wages. Medicare tax applies to all taxable wages with no annual limit. Employers also withhold an additional 0.9% Medicare tax on wages they pay an employee above $200,000 in a calendar year. Employers don’t match this additional tax.

Federal Unemployment Tax Act (FUTA)

FUTA applies to the first $7,000 of each employee’s annual wages, paid entirely by the employer. Because construction work can be seasonal, managing FUTA limits across field crews requires careful tracking, though available state unemployment tax (SUTA) credits can reduce the federal amount owed.

State and local payroll laws

Job location can affect income tax withholding and minimum wage requirements. A contractor running projects across state lines must adjust withholding based on where the work is physically performed, not just where the company is headquartered. States also set pay frequency rules and unique overtime thresholds. For example, California requires time-and-a-half pay after eight hours worked in a single calendar day and double-time after 12 hours. This supersedes the standard federal weekly 40-hour rule.

Prevailing wage and certified payroll requirements

The Davis-Bacon Act applies to federal construction contracts in excess of $2,000. Once a prime contract crosses that line, every covered subcontract under it falls in too, regardless of its own value. The Davis-Bacon Related Acts extend prevailing wage requirements to certain federally assisted projects, and state “little Davis-Bacon” laws have their own coverage thresholds and reporting rules. 

These requirements don’t apply to private commercial or residential jobs. But on covered public projects, payroll must apply precise government-mandated wage determinations and fringe benefits based on exact work classifications.

Contractors must then submit weekly certified payroll reports with a signed Statement of Compliance certifying they paid accurate wages. Falsifying these public records carries both civil and criminal exposure: three times the monetary damages the government sustains or up to five years of imprisonment under 18 U.S.C. 1001.

How to process payroll in construction

Contractors can manage payroll internally or hire a provider. The choice depends on the extent of the work involved and the team’s capacity to handle it.

Manual payroll processing

More than half of companies use spreadsheets for their payroll administration processes. Manual processing avoids dedicated software or provider fees, but it requires office staff to manually cross-reference paper timesheets, look up county-by-county prevailing wage tables, and hand calculate weighted-average overtime rates. In construction, this heavy workload and repetitive data entry can lead to costly errors like forgetting to apply a fringe benefit rate or mistyping a cost code. 

Payroll software

Software automates calculations and can handle tax filings. Construction-specific software also supports job complex costing and project-specific pay rules. For example, a specialized platform can automatically process a field worker’s timesheet split, applying a standard rate and prevailing wage rate depending on the location and work performed. It can also automatically allocate those labor costs to the correct project cost code.

Outsourced payroll processing

A payroll service provider handles agreed-upon administrative tasks, such as calculating net pay and filing quarterly Form 941s. Contractors supply the underlying work records and confirm which project requirements apply. For instance, a regional framing contractor might outsource standard tax withholding and check printing to a national payroll bureau while handling specialized certified payroll reports internally. 

Outsourcing reduces internal processing work, but it doesn’t transfer the employer’s legal liability for payroll taxes and deductions. If a generic payroll provider fails to calculate a prevailing wage correctly or misses a state-mandated daily overtime rule, the contractor remains fully responsible for the resulting back pay penalties, tax liabilities, and compliance violations.

Payroll processing built for construction with Miter

Construction payroll follows standard steps, but each job can bring different pay rules and reporting requirements. Handling these details manually means checking rates against time records and preparing reports from the payroll results. 

When time tracking connects directly to payroll, approved hours flow into pay calculations with their job and classification details attached. Certified payroll reports can then use the resulting payroll data, reducing the need to enter the same information again. 

Miter Payroll connects field time records with payroll calculations and job costing:

• Pay rates matched to recorded work: Configured pay rate groups apply rates and fringe rules based on the job or work classification. Separate timesheet entries allow payroll to account for an employee changing classification during the day.
• Overtime calculations: Once configured, built-in logic supports daily and weekly overtime rules along with weighted-average calculations when employees earn multiple rates in a workweek.
• Reports generated from payroll: Miter generates WH-347 and state-specific certified payroll reports and submits them directly to LCPTracker, eMars, eComply, and Elation Systems, plus detailed union contribution reports.
• Employer costs included in job costing: Integrated accounting mechanisms allocate wages and configured employer costs to jobs and cost codes. Payroll journal entries sync with supported accounting platforms, including QuickBooks and Sage Intacct.

Frequently asked questions

How long does payroll take to process?

Preparation takes minutes or days, depending on complexity and record quality. Direct deposit and pay cards depend on funding schedules, while ACH settlements can happen the same day or take two banking days. Physical checks also require delivery and may take time to clear.

What’s a typical payroll cycle for a construction company?

In construction, 70.6% of businesses pay weekly, more than double the 32.4% rate across all private industries and the highest share of any sector, per the most recent BLS data on pay frequency.. However, some companies pay biweekly. State laws and applicable union agreements can restrict the choice of pay period frequency.

What documents does construction payroll require?

Payroll system setup starts with employee tax forms, including Form W-4 and applicable state forms. Employers also need pay rate information and bank details for direct deposit. Form I-9 verifies employment eligibility. Independent contractors generally provide Form W-9 instead of employee withholding forms.

How does a company distinguish construction workers as employees or independent contractors?

For federal tax purposes, the IRS looks at how much control an employer exerts over working conditions and financial arrangements. The working relationship also counts. State laws may use different tests, so a contract calling someone an independent contractor doesn’t settle the status.

What happens after a payroll mistake?

After a payroll mistake, employers notify affected employees and correct pay promptly. They also update payroll records and affected filings. Tax reporting errors may require Form 941-X or Form W-2c. Unresolved underpayments or tax liabilities can lead to penalties like a Failure to Deposit penalty ranging from 2% to 15% of the unpaid tax and interest accrual.

Who should be responsible for processing payroll at a construction company?

An office manager or dedicated payroll administrator may handle processing, depending on the company size. Field supervisors verify hours and work classifications. A controller or another qualified reviewer checks that payroll applies the correct rates and deductions before authorizing employee compensation.
