HMRC Timesheet Requirements UK: Employer Record-Keeping Rules (2026)
Do UK employers legally need timesheets? HMRC rules on what working time records to keep, how long to store them, and penalties for non-compliance. Includes minimum wage evidence and right-to-work checks.
HMRC requires UK employers to maintain timesheet records proving National Minimum Wage compliance. Missing or inadequate records can result in fines of up to 200% of any underpayment — even if you paid correctly but can't prove it.
What HMRC Requires
1. Record Every Hour Worked
You must record ALL hours worked by every worker (employees, agency staff, contractors):
2. Link Hours to Pay
Records must show that pay received ÷ hours worked ≥ minimum wage rate.
Example:
Employee worked 35 hours, received £385 gross pay
£385 ÷ 35 = £11/hour
✓ Compliant (above NLW of £11.44 for age 21+)
3. Keep Records for 3 Years
HMRC requires records for 3 years from the end of the pay reference period. However, employment tribunals can go back 6 years, so 6-year retention is recommended.
Specific Data HMRC Expects
| Data Point | Why It Matters |
|---|---|
| Worker name/ID | Identifies who worked |
| Date worked | Proves when work was done |
| Start/end time OR total hours | Shows hours each day |
| Unpaid breaks | Deducted from working time |
| Pay reference period total | Links to payslip |
| Gross pay | Proves minimum wage |
| Deductions | Reduces effective hourly rate |
Acceptable Formats
