In 2026, payroll compliance is becoming increasingly important due to digital reporting requirements, Real Time Information monitoring, and rising HMRC compliance activity.

| Number of Employees | Monthly Penalty |
|---|---|
| 1 to 9 employees | £100 |
| 10 to 49 employees | £200 |
| 50 to 249 employees | £300 |
