Hi, I have submitted my self assessment registration on 1 Sep 2024, but still not yet received any UTR, therefore I re-submitted again on 28 Sept 2024. On 29 Sept, I resubmitted my registration again with the address same as my personal tax information in the gateway. I am afraid I cannot receive the UTR before the paper submission deadline on 31 Oct. How should I know HMRC get my self assessment registration, shall I call them? Or I should submit a self assessment registration by post.
