You must tell HM Revenue and Customs (HMRC) if you’re either:
- leaving the UK to live abroad permanently
- going to work abroad full-time for at least one full tax year
The tax year runs from 6 April to 5 April the next year.
You do not need to tell HMRC if you’re leaving the UK for holidays or business trips.
How to tell HMRC
How to tell HMRC depends on whether you fill in a tax return or not. It also depends on your employment status.
If you don’t usually complete a Self Assessment tax return
If you’ve already left the UK, fill in form P85 online. If you haven’t already left the UK, download and fill in form P85 offline.
Include Parts 2 and 3 of your P45 form - get these from your employer (or Jobcentre Plus if you’ve been claiming Jobseeker’s Allowance).
If you usually complete a Self Assessment tax return
You can tell HMRC you’re leaving through your Self Assessment tax return. Complete the ‘resident’ section (form SA109) and send it by post. You cannot use HMRC’s online services to tell them you’re leaving the UK.
You can also complete your Self Assessment tax return with:
You’ll be charged a penalty if you do not meet the deadline - It’s 31 October if you send your return by post.
What happens next
You need to let other people know if you’re moving or retiring abroad, for example your local council, so you stop paying Council Tax.
If you’re owed a refund
HMRC will work out if you’re owed a refund for the tax year you’re leaving the UK.
Tax if you’re non-resident
If you’re non-resident, you do not pay UK tax on income or gains you get outside the UK. You may be non-resident the day after you leave the UK - this depends on your situation and how ‘split year treatment’ applies to you.
You may need to pay UK tax if you’re non-resident and have UK income. For example, you could be taxed if you have income from renting a property in the UK.
The UK has ‘double taxation agreements’ with many countries to make sure you do not pay tax twice.
You might be able to pay National Insurance while you’re abroad if you’re planning to:
- come back to the UK
- claim the State Pension later
You cannot claim back any National Insurance you’ve paid in the UK if you leave the UK permanently. However, anything you’ve paid might count towards benefits in the country you’re moving to - if it’s one of the countries that have a social security agreement with the UK.
If your circumstances change
Contact HMRC if your circumstances change when you’re abroad - you move house or your marital status changes, for example. You’ll need your National Insurance number.
You also need to tell HMRC if you come back to live in the UK.
Visiting the UK
You can visit the UK without becoming resident again - depending on why you visit and how long you visit for.
If you work full-time abroad, you can usually visit the UK for up to 90 days - as long as you work no more than 30 of these days.
You might become a UK resident again if you start new activities in the UK after you’ve left, for example you get involved in a business or buy a new property.
Check your residence status if you’re not sure how your activities in the UK affect your status.
