Hello, I left my job in October 2023 and left the UK in November 2023 (my salary used come in the PAYE system). However, I have received a freelance contract payment of £>1000 in February 2024. Do I need to report the freelance income for taxes in the UK? For context, I have lived in the UK for the last 3 tax years. And suppose I report the freelance income and also seek refund on my taxes before leaving the UK. Can you suggest what is the correct order to do this? Should I report the freelance income first or if I should fill up the P85 first? Second, since I have left the UK what is the quickest way for me to fill uk the self assessment for freelance income? Thanks:)
