This calculator reassesses the National Insurance contributions for a company director using an Annual Earnings Period at the end of the financial year, or during the year, if the directorship ends. If the director is appointed part way through the year the Annual Earnings Period check is calculated on a pro-rata basis from the week in which he or she was appointed.
Further information can also be found in the National Insurance for Company Directors, booklet CA44 (PDF 205K).
This reassessment should only be carried out when the final payment is being made to the director at the end of the tax year, and only during the year if the directorship ends. It will not perform any other in-year assessments.
This calculator will only calculate National Insurance contributions for the current tax year 2011-12.
