Overtime rules and how hours are calculated
Overtime thresholds vary by jurisdiction and employment type. In the United States under the Fair Labor Standards Act (FLSA), non-exempt employees earn overtime at 1.5× their regular rate for all hours worked beyond 40 in a workweek. Several US states (California, Alaska, Nevada) additionally require daily overtime at 1.5× for hours beyond 8 in a single day, and double-time for hours beyond 12. In the European Union, the Working Time Directive caps the average working week at 48 hours (including overtime) over a 17-week reference period, with a minimum of 11 consecutive hours rest per day. Always verify the applicable rules for your employment contract and jurisdiction.
| Jurisdiction | Weekly overtime threshold | Daily overtime threshold | Rate |
|---|---|---|---|
| USA (Federal FLSA) | > 40 hrs/week | None (federal) | 1.5× |
| California (USA) | > 40 hrs/week | > 8 hrs/day (> 12 = 2×) | 1.5× / 2× |
| EU (Working Time Directive) | > 48 hrs/week (avg) | Varies by member state | Varies |
| Australia (NES) | > 38 ordinary hours/week | None federally | Typically 1.5× / 2× |
| UK | > 48 hrs/week (avg) | None nationally | Contractual |
Timesheet accuracy and record-keeping best practices
Accurate timesheets are essential for payroll compliance, client billing, and project cost tracking. Enter clock-in and clock-out times promptly — reconstructing them from memory at the end of the week introduces errors. Record breaks separately from work time; many jurisdictions require employers to document rest breaks for compliance. For client billing, note the project or task code against each time block to simplify invoice generation. Retain timesheet records for at least three years in most jurisdictions (the IRS recommends four years for payroll records in the US; HMRC recommends three years in the UK). Discrepancies between timesheets and payroll records are among the most common triggers for wage-and-hour audits.
