  • A1 form required?

    I have a Ltd company (with 1 employee i.e. myself) and I have been doing a contract for a Norwegian company but working from home in the UK. (i have dual nationality UK/Belgium and i have a full 26 year of NI contributions in the UK) they are now asking for an A1 form - is this required? I tried filling out the CA3821 form to begin with but struggling with some of the information required.
