Registered for self-assessment using SA1 but now need to setup a sole trader

Hello, In Feb I registered for self-assessment using SA1 form to report on my CGT on shares. I already have received a URT. Recently I started doing freelance work for a foreign company and the income will be more than 1000 pounds. I saw on HMRC website that I should register as a sole trader. In this case, can I use the same URT for self-assessment as a sole trader? if not, do I need to register for self-assessment again (using a different form?). Thanks. Kind Regards, Fai

Hi
You will use the same UTR number and will need to complete a CWF1 form to register as Self-Employed.
Register for Self Assessment
Thankyou.
