Client asking for UTR reference

Hello. If I'm a sole-trader, and a client is asking for my UTR code, should I refuse to share this? My understanding is my UTR is private, and should not be shared. But there seems to be conflicting information online. Can you clarify: 1) Should we avoid sharing our UTR? 2) Why might a client ask for it or require it? 3) Do platforms like Worksome require a UTR to validate me as a business entity? Is there an alternative way to show I am registered as a sole trader?

Hi,

Like your national insurance number (NINO), please keep your Unique Taxpayer Reference (UTR) secure and avoid sharing it with unauthorised / unknown parties.  Their should be no reason

why your client would require your UTR, as the UTR is only of use to HMRC.  Other non government platforms should not be using your UTR as a means of identifying you.

Thank you.

OK - that's good to know, thankyou. I'm also being asked for it via Worksome, which is a platform for freelancers. They've said they need it to confirm I'm self-employed? Is that right?

Hi,
Giving sensitive, personal information to other people, even without realising, puts you at risk.
