Hello, I am currently a full-time employee working for a UK company. However, I am planning to move abroad to an EU country permanently (not only for a couple of weeks/months). What I am going to do is: * Resign from my current role as a full-time employee, and get P45 form * In the EU country, work as a self-employed person providing consultancy services to the UK company My questions are: * What form, if any, do I need to submit in the UK, to let HMRC know that I am no longer an employee? * Will I be liable for any tax in the UK after leaving permanently? * Do I immediately become a non-UK resident since I will be leaving permanently? * Do I need to file a self-assessment form for the 2025-2026 tax year? Thank you.
