I moved from HK to UK in Aug 2023 wit BNO visa, on going I still keep to work for a HK company as part-time administrator and received monthly fixed salary (equivalent not more than GBP500 per month). As I still have foreign income (saving interest and dividend to report), so I need to do self-assessment. As I don't have employment contract with this HK company, so I am not sure whether this belongs to income or self-employed income. And I do not have PAYE code for this income. My question: Where can I input those overseas part-time salary in SA100 form ? Thanks.
