Where Is My UTR Number?

Your Unique Taxpayer Reference number (UTR) is a 10-digit number you’ll receive after registering for Self Assessment or setting up your own limited company.

Starting a new business is an exciting time, but can also mean lots of information flying about that you need to keep track of. Hidden within the onslaught of letters and emails will be your UTR number.

This is an important reference number for your business, so we’ll answer some of the most frequently asked questions surrounding your UTR and where you can find yours. Grab a cuppa, and have a read.

What does a UTR number look like?

UTR numbers are fairly easy to spot. Sometimes also called a tax reference number, it takes the form of a 10-digit number that look something like 12345 67890. Everyone will have their own unique number, so don’t worry if yours looks different to someone else’s – it’s supposed to!

What is the purpose of a UTR number?

Similar to your National Insurance number, your UTR is a personal tax reference number that’ll stick by you through your working life (or your limited company, if you set one up). It’s used to identify who you are, how much tax you owe, and what your tax obligations are.

It’s HMRC’s way of ensuring you make the correct payments, and also helps them to watch out for any suspicious activity on your account.

You’ll need a UTR number to:

When will I receive my UTR number?

You’ll receive your UTR number in the post within 10 days of setting yourself up for Self Assessment or registering your limited company. If you need it sooner, log into your Personal Tax account or the HMRC app – it should be there a little earlier.

Do I need more than one UTR number?

This depends on what sort of business you operate. If you’re a sole trader you’ll only have one personal UTR number, even if you have multiple sole trader businesses. As a sole trader you aren’t legally separate from your business, so all your different sole trader roles are seen as one legal entity.

If you’re operating a limited company, you are seen as a separate entity from your business, so you’ll have:

Anyone running multiple limited companies will need a separate UTR number for each one to submit its own Company Tax Return. If you do have multiple UTR numbers, file them away somewhere safe so you don’t get them mixed up!

What happens if I don’t receive my UTR number or if I lose it?

If you’ve either lost your UTR number or have yet to receive one (and it’s been over 10 days since you registered), you can request it via the Self Assessment helpline.

If you need your limited company’s UTR number, you can request a copy of it online.

Who do I give my UTR number to?

Your UTR number is unique to you and shouldn’t be shared around to just anyone. You should only really need to give it out if:

Is my Government Gateway ID the same as my UTR number?

Your Government Gateway ID and your UTR number are different.

Whilst your UTR number identifies your tax records, you’ll need your Government Gateway ID to login to various online services, such as the HMRC portal for submitting your tax returns. It’s 12 digits long and usually looks like this: 123123123123.

You can find your UTR number on your Government Gateway account, by logging in and looking under your account summary, or the Self Assessment tax section in your account. You can also log into the HMRC app and find it in your Personal Tax Account.
