How to Claim Back Tax on Form P45
A Form P45 shows your wages and tax that was deducted for the tax year in the UK. You receive this form from your employer if you stop working for them. You may be able to claim back tax on the Form P45. The P45 form has 4 parts. Your employer sends Part 1 to HMRC and you receive the other three parts.
- Make sure your employer gives you a P45 Form if you stop working for them. It is required by law that they give you this form at the end of your employment. It does not matter why you quit working for them. You may have retired or found a better job.
- Navigate to the HM Revenue and Customs website to claim back tax on Form P45. Find the Form P50. This form should be called “Claim tax when you stop working.”
- Fill out the form. When you are finished, go over it very carefully and make sure everything is correct. If you make one mistake on the form, it will be sent back to you and you will have to start the process over again.
- Find a UK tax office in your area. There is an office locator on the HM Revenue and Customs website if you do not know where a UK tax office is. Enter your zip code or three digit tax code and click the “Search” button. Write down the address to the UK tax office.
- Mail the Form P50 that you printed from the website and filled out. Make sure you mail parts 2 and 3 of the P45 you received from your employer. Keep Part 1A for your records. You will be sent a refund check in the mail if one is due to you.
