What is a UTR number?

So you’ve started your own self-employed business, and now you need a UTR number to get going. What is UTR? UTR stands for Unique Taxpayer Reference, which is a ten-digit reference assigned by HMRC in order to track your tax records. UTRs are only issued when an individual has been accepted as being self-employed with their own name or their trading name. In this article we will look at the process of getting a UTR number and why it’s so important!

Who needs a Unique Taxpayer Reference number from HMRC?

If you’re self-employed, then you will definitely need a UTR number. You cannot file your tax return without it. In addition, if you’re employed but also have some self-employed income, then you will also need to apply for a UTR number. Basically, if you have any dealings with the taxman at all, then you will need this reference number.

If you’re a limited company then your UTR number as an individual will be different from your company tax reference number, you will need your individual UTR number whenever you correspond with HMRC or complete a Self Assessment tax return.

The process of getting your UTR number is very straightforward. First, you need to create an account with HMRC online services. Once you’ve registered, you will be able to apply for your UTR number directly on the website. It usually takes around two weeks for HMRC to assign your UTR, and they will send it to you in the post.

Difference between Company UTR and Personal UTR

HMRC issues personal UTRs to people who are self-employed, including contractors, freelancers and UTRs for construction workers. If you’ve been issued with a UTR by HMRC then it is because your income falls into the taxation category as an earner of self-employed earnings.
