Maximum National Insurance contributions calculator
If you earn income from more than employment or self-employment (including a share of partnership profit) in the same tax year, you are usually required to pay NI on each. This may result in you overpaying contributions, although it’s still possible to underpay, which could jeopardise your state pension rights.
Using the calculator
The calculation required to check NI contributions can involve a number of steps. Using the minimum data our calculator works out whether you have paid too much or too little NI and produces a report you can send to HMRC to support a claim for repayment, if appropriate.
