A P45 is issued to an employee who is leaving their job. It includes details of the taxable pay and how much tax has been deducted. You must give a copy of the P45 to your new employer so that they deduct the correct amount of tax.

Your tax code will be based on the information you will have provided on the New Starter Form. However, if you still believe you are on the wrong tax code, you need to call HMRC on 0300 200 3300 with a copy of your latest payslip.
This can be found on the bottom right of your payslip. It is normally in the format 120/AB12345
