Contractor Overtime Source-Gap Guide

How to separate federal, state, regular-rate, prevailing-wage, CBA, payroll, and safety review items before relying on overtime arithmetic

Overtime pay review starts with a simple question - how many hours are premium-paid in the workweek - but the answer depends on sources that a quick calculator cannot prove. FLSA coverage, exemption status, compensable time, regular-rate inclusions, state daily overtime, local ordinances, prevailing-wage rules, CBA language, payroll-system setup, and certified-payroll records all matter.

This guide treats overtime as a source-gap review. Use the linked screen to organize wage arithmetic and source pointers, then reconcile the result with current DOL, state, wage-determination, employer, union, safety, and qualified legal or payroll review before operational use.

Start With The Workweek And Regular Rate

The DOL FLSA source pointers describe overtime on a workweek basis for covered non-exempt employees. That means the review packet needs the actual employer workweek, all hours worked, and the regular-rate basis before any premium row can be trusted.

The regular rate is often broader than the entered hourly wage. Shift differentials, nondiscretionary bonuses, piece-rate earnings, multiple job rates, certain per diem, salary arrangements, and statutory exclusions all need payroll or legal review. The calculator can show the arithmetic, but it cannot decide which payments belong in the regular rate.

Warning: Source gap: The app does not decide exemption status, compensable travel, training, pre-shift, post-shift, on-call, break, or standby time. Pull time records and current source review before payroll use.

Treat State Rows As Current Source Checks

California, Alaska, Colorado, and Nevada source pointers each raise different questions. California has daily, double-time, seventh-day, alternative-workweek, wage-order, and exception details. Alaska has daily overtime and employer-size or flexible-plan questions. Colorado includes a 12-consecutive-hour concept that day totals cannot prove. Nevada daily overtime depends on wage-threshold, 4x10, and exemption details.

Do not treat a state row as a universal rule. Verify the state where work is performed, current agency guidance, local ordinances, industry rules, wage orders, exemptions, and any CBA or employer policy that changes premium pay.

Timing matters: Cross-week consecutive days, split workweeks, alternative workweeks, and 12-consecutive-hour rules require time records, not just day totals.

Avoid Counting The Same Hour Twice

A useful screening pattern is to mark daily premium-paid hours first, then add weekly overtime only when hours over 40 exceed the already premium-paid hours. That keeps the same hour from receiving two overtime premiums in the local arithmetic.

This is still not a universal legal answer. Some contracts, public-sector rules, holiday premiums, wage orders, or employer policies may define premium stacking differently. Keep the no-duplicate logic visible as an assumption and review it against the governing source.

Tip: Review packet: Show daily-only, weekly-only, and additional-weekly rows so the reviewer can see exactly where the premium hours came from.

Pull The Records Before The Calculator

Before relying on a wage screen, collect time records, workweek definition, job classifications, pay codes, shift differentials, bonuses, per diem policy, travel rules, CBA or handbook language, payroll-system setup, and any state-law or local-law source that applies to the work location.

For prevailing-wage work, add the contract clauses, wage determination, worker classification, apprentice registration and ratio records, fringe-benefit documentation, certified payroll records, and CWHSSA/FLSA overlap review. For long weeks, add fatigue, driving, safety-sensitive task, rest, and supervisor approval records.

Warning: Do not skip classification: Employee/contractor status, exempt/non-exempt status, apprentice status, and trade classification are source questions, not calculator outputs.

Build A Review Packet

A practical review packet separates arithmetic from authority. Put the entered schedule, rate rows, premium rows, source pointers, warnings, and residual gaps on one page. Then attach the payroll records, state source, CBA or policy language, wage determination, and reviewer notes that decide whether the arithmetic belongs in payroll.

The linked screen is useful when it makes those unresolved questions visible. It is not useful if the output is copied into a check run without source review.

Tip: Review order: Confirm coverage and hours worked, then regular-rate inputs, then state or CBA premium rows, then prevailing-wage or certified-payroll details.

Frequently Asked Questions

No. It identifies source gaps. Coverage, exemption status, hours worked, regular rate, state law, CBA terms, employer policy, and qualified review decide actual payroll.
Use it only as an estimate. California wage orders, alternative-workweek validity, seventh-day patterns, meal/rest premiums, exemptions, and legal review remain outside the app.
Start with the wage determination, classification, fringe documents, apprentice status, CWHSSA/FLSA overlap, and certified payroll records. The app only shows a flat local fringe row.
The entered hourly wage may not be the full regular rate. Differentials, bonuses, multiple rates, per diem, salary, and exclusions need payroll or legal review.
Review fatigue, commuting, driving, heat, noise, machine operation, supervision, rest controls, incident history, and safety-sensitive work before using overtime as a staffing plan.
