Maybe you received a full-time job or are just ready to stop your self-employed business. Whatever the case, if you stop being a sole trader, be sure to follow these HMRC rules.
Do I have to tell the HMRC if I stop being self-employed?
Yes. You must tell the HMRC when you stop being a sole trader. This is important to do because the HMRC will cancel your Class 2 National Insurance contributions. You must also cancel your VAT registration if you or your partnership had one.
