Who publishes it
Overtime Calculators is published and maintained by Gazala. Gazala chooses the sources, approves every update and handles corrections. The site does not claim any legal, tax or payroll accreditation. It is an information tool, not tax or legal advice, and it is not affiliated with the IRS, the U.S. Department of Labor or any state agency.
Sources
- 29 USC 207 and 29 CFR 778.110: federal overtime and the regular rate.
- U.S. Department of Labor, State Minimum Wage Laws: state overtime rules.
- California Labor Code 510 and Colorado COMPS Order Rule 4.
- 26 USC 225, 26 USC 224, Schedule 1-A and IRS FS-2026-13: the overtime and tips deductions.
- Treasury final regulations TD 10044: qualified tips and the tipped occupation list.
How it is checked
- Automated tests run the calculators against the worked examples printed in the rules, published on the test cases page. The site is not built if any of them fails.
- Results are compared with other published calculators; where they differ, the rule's own text decides.
- The "rules checked" date, currently October 19, 2026, is the day every rule was last read from its primary source.
When it is updated
IRS guidance on the deductions changes most often around filing season, so every rule is re-read each January and whenever the IRS, Treasury or a state changes it. Gazala approves each change before it goes live. The deductions apply to tax years 2025 to 2028; after that, those pages will say so.
Corrections
If you think a number is wrong, tell us on the contact page with the inputs you used and what you expected. Confirmed errors are fixed and noted with the date.
How the site is made
Parts of this site were built with the help of AI tools. The calculations are checked by automated tests against the official examples, and the pages are read by Gazala before they are published.
Advertising and privacy
The site may show ads once it is live. Ads never change a result. There are no loan, credit or payday-advance offers here. The calculators run in your browser; your numbers are not sent anywhere.
