Overtime rules used to be a purely operational question — how much do I get paid for that extra shift. Since 2025 there's a tax angle too, and it's one a lot of eligible workers still don't know applies to them. Here's how the hours math works, plus what changed on the tax side.
How Work Hours Are Calculated
Total hours = (End time − Start time) − Break time. For clock times: convert to 24-hour format, subtract start from end in minutes, subtract break minutes, convert back to hours and minutes. For a 9:00 AM to 6:30 PM shift with 45-minute lunch: (9h 30m) − 45min = 8h 45min (8.75 hours). The calculator handles AM/PM conversion and overnight shifts automatically.
US Overtime Pay Rules (FLSA)
The Fair Labor Standards Act (FLSA) requires overtime pay of at least 1.5× the regular rate for non-exempt employees working more than 40 hours in a workweek. A workweek is any fixed 7-day period defined by the employer — it doesn't have to be Monday through Sunday. Important: overtime is calculated weekly, not daily under federal law. However, California, Alaska, and some other states require daily overtime (1.5× after 8 hours/day; 2× after 12 hours/day).
| Hours Worked | Pay Rate | Example ($20/hr) |
|---|---|---|
| 0–40 hours | Regular rate | $20/hour |
| 40–60 hours (federal) | 1.5× regular | $30/hour |
| Over 12hrs/day (CA) | 2× regular | $40/hour |
Why Time Tracking Matters for Everyone
Hourly employees: ensure you're paid correctly — wage theft (unpaid time) is surprisingly common. Review your paystub for correct hours. Salaried employees: tracking hours reveals effective hourly rate and work-life balance trends. Project managers: hours data improves future project estimates and pricing. Business owners: employee hours are the foundation of labor cost analysis.
💡 If you believe your employer is not paying correct overtime, the Department of Labor has a wage theft complaint process at dol.gov. Employers who owe back wages must pay them plus potential penalties.
The New "No Tax on Overtime" Deduction
Since 2025, FLSA-eligible non-exempt workers can deduct the "half" portion of their time-and-a-half overtime pay from federal taxable income — up to $12,500/year ($25,000 if married filing jointly), through 2028. Only the premium portion counts: on $30/hour overtime pay against a $20/hour regular rate, just the extra $10/hour is deductible, not the full $30. It phases out starting at $150,000 MAGI (single) or $300,000 (joint). A few things trip people up: it only applies to overtime required by the FLSA — daily overtime under California-style state rules, collective-bargaining overtime, or voluntary employer bonuses don't qualify. It's a deduction claimed on your tax return, not a withholding change, so your paycheck won't visibly change; the benefit shows up as a bigger refund or smaller bill at filing time. And it doesn't touch Social Security, Medicare, or state tax — those still apply in full. Starting with the 2026 tax year, employers must report qualified overtime separately on your W-2, which makes claiming it far easier than it was for 2025.
Freelancers and Contractor Time Tracking
For hourly-billed freelancers, accurate time tracking is essential for both fair billing and business analysis. Tools: Toggl Track (free, excellent), Harvest (billing integration), Clockify (free, team-capable), or even a simple spreadsheet. Track at the project and task level — this data reveals which clients and project types are most profitable per hour and helps improve future rate quotes.
Time Management Insights from Tracking
Time tracking reveals surprising patterns: context switching between projects costs 15-25 minutes of productive time per switch. Meeting time is typically underestimated by 20-30%. Administrative tasks (email, invoicing, scheduling) consume 1-3 hours daily for most knowledge workers. Use this data to restructure your day — block deep work time, batch administrative tasks, and set meeting limits to protect productive hours.
Quick Checklist
- Review pay stubs weekly if paid hourly — verify hours match your records
- Know your state's overtime rules — California and some others differ from federal FLSA
- Track time at the task level for 2 weeks to identify your highest-value vs lowest-value activities
- For freelancers: bill in 6-minute or 15-minute increments to capture all billable time accurately
- Keep time records for at least 2 years (federal minimum for wage claims)
- Use time tracking data to improve future project estimates and pricing
