I apply for self-employment UTR and receive an email that my application was rejected because the address does not match. I am a BNO visa holder from Hong Kong. I use my UK address to apply HMRC self-employment. Unfortunately, My address in UK Visas and Immigration Account have not change yet. Now I have updated my address in UK Visas and Immigration Account from Hong Kong to my UK address. In this case, do I need to make a new application to get a new acknowledgment reference? or how can I contact HMRC that I have updated my address and let the application go on?
