What Happens If Your National Insurance Number Is Wrong?

One of the most common and impactful consequences of having an incorrect National Insurance number is that the financial details regarding your National Insurance contributions can be wrong.

If this error goes on for a long time, there are chances that your National Insurance credits will also be affected. If the records indicate lower National Insurance contributions, you may not be able to claim as many NI credits as you normally would in time when you are not working and not making any NI contributions.

Another consequence of having an incorrect National Insurance number is that you may have difficulty in claiming certain benefits or receive a reduced amount of benefits due to a record that shows lower NI contributions. This can especially be the case when it comes to State Pensions.

Therefore, once you realise that your National Insurance number is incorrectly mentioned in any (or all) relevant documents, you must make immediate efforts to have it corrected.

What Should You Do If You Cannot Find Your National Insurance Number?

If cannot find your National Insurance number, you should first search for it in the following documents:

  • documents such as your payslip or P60 form
  • official letters about tax, pension or benefits 
  • your online Personal Tax account using your Government Gateway user ID and password
  • by filling out form CA5403 and sending it to the address mentioned on the form
  • the HMRC app (if you’ve downloaded it on your mobile)

Otherwise, you can call the HMRC helpline on 0300 200 3500 if you are in the UK or + 44 191 203 7010 if you are outside the UK to ask for your National Insurance number. The HMRC official will ask you certain questions to confirm your identity and personal details. 

It can take up to 15 days for the HMRC to share your National Insurance number after you’ve talked to an official.

Conclusion:

The above discussion helps to conclude that the consequences of having an incorrect National Insurance number on your payslip can be quite impactful, especially in the case of your financial records regarding NI contributions. Therefore, it is advisable to inform your employer or the HMRC (or both) to have your National Insurance number corrected on your payslip.
