  • Two government gateway ID & Self-assessment form

    Hello, I have accidently created two government gateway ID. Am I be able to cancel one of them? Is it right that I need to register a business tax account, get a UTR and then fill in the SA100 & SA109 form if I would like to use split year treatment with arising basis for my foreign income? What should I fill in for the business address when registering the business tax account if I work in the UK for a company outside of UK? Thank you.
