- Using base hourly wage as the regular rate when non-discretionary bonuses or commissions should have been factored in
- Assuming daily overtime rules apply nationally when they're actually state-specific
- Averaging hours across a bi-weekly or other multi-week period instead of checking each individual workweek
- Assuming all salaried employees are automatically exempt from overtime
- Assuming comp time can substitute for overtime pay in a private-sector job
- Calculating tipped-employee overtime from the direct cash wage instead of the full minimum wage before the tip credit
The General Fix
Most of these errors come from applying a simplified mental shortcut (one rate, one week, one universal rule) to a situation that actually has a specific exception or additional factor — checking for bonuses, commissions, state-specific rules, and correct exemption status before finalizing a number avoids the majority of these mistakes.
Frequently Asked Questions
What's a common mistake with the overtime regular rate?
Using just the base hourly wage when non-discretionary bonuses or commissions should have been factored in.
Is assuming daily overtime applies everywhere a mistake?
Yes — daily overtime rules are state-specific, not a federal or nationwide requirement.
What's a common mistake with salaried employees?
Assuming all salaried employees are automatically exempt from overtime, when exemption actually depends on specific duties and salary-level tests.
What's the general fix for avoiding most US overtime mistakes?
Checking for bonuses, commissions, state-specific rules, and correct exemption status before finalizing a calculation, rather than applying a one-size-fits-all shortcut.
