Hello, I came to the UK for the first time in November 2022 as a Ukrainian refugee. I have zero income in the UK, but during the tax year 2022/2023 I did have income of roughly £9,000 from the foreign freelancing platform. Tax residency test at gov.uk says that I was a tax resident in the UK for 2022/2023, so a few questions arise:
1) Do I have to declare this amount as foreign income, even if some part of it was received before November 2022? If yes, should it be declared as foreign income from being self-employed or differently?
2) Do I have to pay income tax, national insurance tax, or anything else in this case?
3) Do I have to register myself as a sole trader in the UK prior to declaring this income?
Thanks a lot!
