HI, I am PAYEE employee and I submit my tax returns through MyAccount. But from next year I will have some non payee income that I need to declare, so I need to register for self assessment and submit form 11. As per my research in order to do this electronically I need to register for ROS. I tried but I am not able to do this with my PPS number and I am not self employed. Any advice please? Many thanks. Also, can I cover my tax liability with the future tax credits?
