UK Tax Identification Number

[Max1834]

I'm am just signing up as a host and I'm being ask for my "Tax Identification Number", with no explanation of what this refers to. What should I use? My NINO? I haven't submitted any tax returns, and probably won't ever need to since my income will be below the threshold, so I don't have a UTR.

@Max1834 you can try your NI number but it has letters as well as numbers so may get rejected. You can get a tax number just by doing a self assessment return even if you don't end up paying any tax.
