Deregistering from the UK for tax purposes is an important process that needs to be completed correctly to avoid any potential issues. If you are leaving the UK to live in another country permanently, you will need to inform HM Revenue and Customs (HMRC) of your non-UK tax residency status. Here is a step-by-step guide to help you through the process:

  1. Notify HMRC: The first step is to let HMRC know that you are leaving the UK for another country. You can do this by filling in a P85 form or by informing them through your Self Assessment tax return.
  2. Gather required information: You will need to provide HMRC with your personal details, including your full name, date of birth, National Insurance number, contact details, and the date of your departure from the UK. You will also need to provide information on your UK income and employment.
  3. Provide details of your overseas address: You will need to provide HMRC with your new overseas address and contact details. This will allow them to send you any correspondence that is relevant to your UK tax affairs.
  4. Provide details of your income and employment in your new country: You will need to provide HMRC with details of your income and employment in your new country. This will help them determine whether you are still liable to pay UK tax.
  5. Await response from HMRC: Once you have submitted your P85 form, you should receive a response from HMRC within a few weeks. They will let you know whether you are entitled to a tax refund and whether you need to continue paying UK tax.
  6. Cancel your National Insurance contributions: If you are leaving the UK permanently, you should cancel your National Insurance contributions. You can do this by contacting HMRC and letting them know that you are no longer liable to pay UK National Insurance.
  7. Update your bank and other financial institutions: You should also inform your bank and any other financial institutions that you are leaving the UK. This will ensure that they are aware of your new address and contact details.

By following these steps, you can successfully deregister from the UK for tax purposes and inform HMRC of your non-UK tax residency status. It is important to remember that you may still be liable to pay UK tax on some income, such as rental income from UK property, even if you are no longer a UK tax resident. It is advisable to seek professional advice to ensure that you are complying with all relevant tax regulations.
