Payroll year end process - IRIS Payroll Business / Bureau
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.

It's good practice to check all directors National Insurance calculations, especially if they became a director mid year.
