Hi HMRC tax advisor, I hope this message is finding you well. 1. I had a full-time job in HK and my last work day on March 2023. 2. I moved to UK on 3-Apr, 2023. 3. I received the salary from HK employer on 6-April, 2023. The payroll month is actually March 2023, but I received it in 6-April, 2023. 4. I got an offer from UK company and start to work from May, 2023. 5. I've lived in UK since 3-Apr, 2023, until now. Q1. I believe I am a UK tax resident in the tax year 2023/2024. Do I need to file self assessment tax return for the salary received from HK employer? Q2. If yes,do I only need SA100? or there are other forms I need? Thank you so much.
