I recently received my P45 from my previous employer, and I noticed an error in the leaving year. The correct date should be 24-04-2023, but on the P45, it is mentioned as 24-04-2026. I have contacted my previous employer regarding this issue, and they informed me that the payroll department had submitted the correct dates. They also mentioned that it may not be possible to change the incorrect information on HMRC's side due to the potential duplication that could occur.
I would greatly appreciate it if someone could provide me with advice on how to proceed in this situation.
