Your employer must give you a form P45 when you leave your job.
The form has 4 parts. Your employer will:
You should keep part 1A of the P45 and give parts 2 and 3 to your new employer so they can continue operating the same tax code shown on the form. Your new employer will keep part 2 of the P45 and send part 3 to HM Revenue & Customs (HMRC) to inform them that you have started a new job.
Your P45 also tells your new employer if you are making student loan repayments. Without the form your new employer will be unable to carry on taking student loan repayments until the Student Loans Company issue a new start notice.
If you have a student loan and stop making repayments when you start a new job you should contact the Student Loans Company (Opens new window) to check if you should still be making payments.
