Step 4: Check Directors National Insurance (NI) calculation

If you discover a mistake after the 15th April covering the previous tax year, you need to preform a Previous Years FPS.

If you started using the payroll partway through the tax year and imported your data from another payroll system, check year-to-date NI calculations for Directors.

Follow HMRC leaflet CA44 National Insurance for company directors or use the Director’s National Insurance contributions calculator.
