CORRECTING AN EMPLOYEE NO & HOW TO ADVISE HMRC AS THE EMPLOYER

In M10 22/23 We transferred an employee to a different company with the same PAYE reference. Unfortunately we didnt keep the employee number the same. This resulted in the employee getting a tax refund in error from HMRC. It seems that HMRC cannot see the M1-M9 22/23 figures, why is this? I have been advised to correct the employee number in 22/23 and send a revised FPS. To do this I have to change the employee number in 23/24. Will this cause additional problems? I have also bee advised to tell HMRC what i have done. Who do i call to do this as as far as i am aware the Employers Helpline cannot see employees details and as the employer I cannot talk to the Employees Helpline? Thanks in advance peps

Hi JW0823,

You may need to speak to your software provider for advice on how to correct this.

Thank you.
