  • Late submission of Self Assessment

    I'm a new migrant to the UK. I have only realised that I need to file a self assessment recently. I sent a paper form SA109 for applying split year treatment last week. Knowing that the deadline of self assessment is 31 January, could you kindly advise whether I can submit a separate SA109 and self assessment via online platform and withdraw the paper form now? Thank you for your help.
