Stripe Tax Details for the UK


I completely appreciate the true answer to this question really should come from Stripe but even after going through their support for the last week I struggling to get an answer/solution.

Has anyone set themselves up as a sole trader (based in the UK) in Stripe? If so did you add any tax information? Ive been told I need to update my Tax details in Stripe (see image) Which I have tried to do and it is not accepting any of my details (UTR or NI number). I’m getting a bit concerned due to the warning messages around disabling charges etc hence reaching out on here.

Many Thanks,
