Non-resident people are people who work in the UK but only temporarily, so their primary tax residence is not in the UK. They only pay tax on their UK earnings, not money earned from abroad.
The main criteria for being considered a non-resident:
- either be physically present in the UK for less than 183 days in a tax year. Not calendar year: a tax year starts on April 6th and ends on April 5th of the following year
- or if you have a home in the UK, it’s not your only home, and you also haven’t lived in it for more than 90 days in the past tax year.
When you might need to file a tax return in the UK if you’re non-resident:
- if you sold a property or other assets for profit (except shares)
- if you earned rental income
- or if you were self-employed.
If you were just full-time employed in the UK for a short while, you don’t need to do anything. Your employer already takes care of your UK taxes for you.
