Common Overtime Mistakes That Cost Pay
Avoid overtime mistakes that lead to underpaid wages, including wrong workweeks, wrong regular rates, state-law misses, and exemption errors.

Most overtime mistakes are not exotic. They come from using the wrong hours, the wrong regular rate, the wrong state rule, or the wrong exemption label.
This checklist covers the mistakes that most often lead to underpaid overtime and shows where to verify the calculation inside OvertimeIQ.
Calculate state overtime
Choose your state to estimate weekly overtime, daily overtime, double time, and state-specific wage rules.
1. Averaging two workweeks together
Overtime is usually calculated by workweek. A 48-hour week and a 32-hour week do not cancel each other out under the federal weekly overtime rule.
2. Treating salary as automatically exempt
Salary is only one part of the exemption analysis. Duties, salary basis, and salary level also matter. If the worker is salaried but non-exempt, overtime may still be owed.
Review exempt vs nonexempt overtime3. Ignoring bonuses and premiums
Non-discretionary bonuses, commissions, shift differentials, and some incentive payments can increase the regular rate. If payroll excludes them, overtime may be too low.
Recalculate the regular rate4. Missing daily overtime states
A federal-only calculation can miss overtime in states with daily triggers, double-time rules, seventh-day rules, or industry-specific wage orders.
Start with the state calculator hub5. Leaving remote work off the clock
Off-hours messages, short support tasks, required logins, and interrupted meal breaks can count as hours worked. Remote teams need a clear reporting process and a way to correct missed time before payroll closes.
