The short version: A Unique Taxpayer Reference (UTR) is a 10-digit number HMRC uses to identify you for Self Assessment. You need it to file tax returns and for various dealings with HMRC.
How do you get one?
Register for Self Assessment and HMRC sends you a UTR by post within a few weeks. Keep it safe because you’ll use the same number forever.
When do you need it?
Filing tax returns, setting up your Government Gateway account, sometimes when dealing with accountants or mortgage lenders, and occasionally when working as a subcontractor in construction.
Are there different types?
Individuals have personal UTRs. Partnerships have partnership UTRs. Companies have their own Corporation Tax UTRs. They’re all 10 digits but used for different purposes.
What if you’ve lost it?
Check previous tax returns, correspondence from HMRC, or your Personal Tax Account online. You can also call HMRC and they’ll confirm it (after verifying your identity).
