For FY2023/2024 my only source of income has been from my UK employer as PAYE until beginning of July 2023, paying taxes in UK, then I moved to Italy where I started receiving a salary from my current Italian employer and paid taxes in Italy. I filled and issued the P85 form accordingly communicating the move in July, and received the response from HMRC. Do I also need to fill out a self-assessment? I have no other sources of income and never had to fill out a self-assessment before. Thank you.
