Company Unique Tax Reference Number
Every limited company has a Unique Tax Reference (UTR) number given by HMRC.
This reference, comprising of 3 digits followed by 10 digits, is quoted on any letters from HMRC regarding your company's Corporation Tax affairs.
Tempo, as your accountant, will need to know this reference number in order to file company accounts.
If you have received any correspondance directly from HMRC please email a copy of the letter to Tempo's support team.
