Hi, I arrived in the UK on 24th July 2023. At that time, I was previously employed by a Hong Kong company on a contract basis, which allowed me to work from home in the UK until 1st October 2023. Aside from my foreign employment, I have set up an Individual Savings Account with a UK bank and have been receiving interest regularly. I was wondering whether I need to sign up for Self Assessment Return this tax year and pay for National Insurance or not. Thank you for your clarification.
