New sole trader on eBay when to get UTR from HMRC

Marky19

Hi there 

I’ve just started to trade on eBay from this week April 6th 2025
im aware of self assessment and the £1000 trading allowance which I know I will surpass in the next few months! 

Questions 
1. when do I need to register for self assessment ? Is it after a full year of trade now I.e after next April 2026? Register by October 5th and then submit? 

Also do I get my UTR When I do this or do I need to get this prior/earlier? 

Many thanks 
Mark

There is no harm in registering for it now, having started in the 25/26 year you're obliged to register late 2026 (can't remember the date off hand) and the first return due by end Jan 2027

I agree with the above, there's no reason you can't do it now. Check the details and what you need to do with HMRC, they're friendly enough.
