What is a P45 and what if I don't have one in the United Kingdom (UK)?

A P45 is an important document provided by your employer when you leave a job. It details your earnings and the tax you've paid during the current tax year.
When starting a new job, your new employer uses the P45 to ensure your tax is calculated correctly. If you don't have a P45, whether due to a delay, it being lost, or because you're entering the workforce for the first time, there are steps you can take to make sure your tax affairs are in order:


​

  1. Complete a Starter Checklist (Previously Known as P46):

    • Remote People will ask you to fill out a Starter Checklist, which serves as a replacement for the P45. This form collects essential details about your employment history and current situation.

    • The information you provide on the Starter Checklist helps Remote People assign the correct tax code to ensure you pay the right amount of tax.

  2. Inform Remote People:

    • Notify your new employer as soon as possible that you don't have a P45. They will guide you through the process and use the Starter Checklist to determine your tax code.

  3. Monitor Your Payslips:

    • After submitting the Starter Checklist, regularly check your payslips to make sure your tax code is correct and that your tax deductions appear accurate. If anything seems off, contact support@joinhorizons.com

  4. Contact HMRC if Necessary:

    • If you encounter issues with your tax code, deductions, or obtaining your P45, contact HM Revenue & Customs (HMRC) for assistance. They can help ensure that your tax affairs are in order and that you're paying the correct amount of tax.


​

By following these steps, you can ensure that your tax is handled correctly even without a P45, helping you avoid potential issues with overpayment or underpayment of taxes in your new role.
