Where Is My UTR Number?

Jun 02, 2019

UTR = Unique Taxpayer Reference. It's a code that HMRC assigns you as a person, or to your company as a legal entity.

Your UTR number is on any letter that HMRC sends you if you have registered a company or signed up directly as a self-employed person.

It's a 10 digit code.

It's that little reference number on the letters they sent you.

Below is a screenshot of a typical HMRC letter. The actual number in this example is, of course, is obscured. A UTR number is an important piece of ID and you should not let other people know it for casual reasons.

HMRC make it tricky to find because they don't make it obvious; it looks like a typical in-house reference number that any major body uses to 'tag' your letters.

It's the sort of thing your eyes gloss over because you're reading the body of the letter.

The code is printed on:

- Payment reminders
- Self Assessment welcome letter
- Notice to file a tax return
- Statement of account
- Your self assessment tax return

The UTR can take a while to come through. HMRC recommend that you leave at least 20 working days (i.e. one month)  to receive your number.
