Wrong NI number on payslip

[tm55]

I just realised today that the NI number in my payslip is wrong. Having looked into my old payslips and P60s it appears it was wrong from the start of job over 8 years ago. There is only one digit wrong which was why it was hard to spot before. However, all the correspondence from HMRC so far has the correct NI number.

I did find other posts with similar problem but still not sure what are the full implications. Obviously I will have to inform my employers and HMRC about this. I am bit concerned if as this has been over 8 years ago.

Can anyone please advise, how do I ensure all of my NI contributions to date are backdated to the correct number? Any other actions I need to take to ensure this issue does not cause any problems in future.

Thank you.

First, find all your old P60s and check the NINO on each one. Copy these and send copies to HMRC with a letter explaining the position. Ask them to confirm to you that your correct account has been credited with these contributions and that there no gap years. To double check, ask them for a pension prediction before and after you notify them. Keep the corrspondence from HMRC.
