Moving Abroad, Income Tax

I moved to Canada in June 2023 and continued working for my UK employer. I now pay income tax to the Canadian CRA. I filed a P85 to HMRC and got an NT tax code. I was refunded all tax paid for the 2023/2024 tax year. Two questions: How do I pay the tax amount for when I was in the UK between 1st April - 19th June 2023 (when I moved)? I assume this will need to be done after April 2024, however, my self-assessment was closed by HMRC when I moved. Will the amount owed be based on my estimated salary for the entire year or just the actual amount I earned between 1st April - 19th June 2023? Any help would be appreciated!

Hi,

The tax will have been deducted up until you left as the NT code should only apply from the day after. The matter will reviewed after 6 April 2024 to confirm if any liability is due and a request for payment will be issued if applicable.

Thank you.
