For most UK businesses, your UTR number is just as important as your company name, and is issued automatically by HMRC when a company is first registered at Companies House. Without a UTR number, your business can’t file its company taxes, and it can also be required for certain applications (to show the business is registered) or government funding and grants.
But what is a company UTR number and what is it used for? In this guide, we’ll explore everything you need to know about company UTR numbers and how find yours for your business. By the end, you’ll have all the info you need to ensure your business is properly registered and compliant with HMRC.
What is a Unique Taxpayers Reference Number?
First of all, what does UTR stand for? UTR stands for “Unique Taxpayer Reference,” and it’s exactly that – a unique reference number assigned to you by HMRC (HM Revenue & Customs).
Unique Taxpayer Reference (UTR) numbers are issued by HMRC to allow you access to your company tax returns, to file tax returns and pay any corporate taxes.
Your Unique Taxpayer Reference Number is what identifies you when you submit your corporate tax return or check your previous tax returns, and are vital for staying on top of your corporate taxes.
What is a company UTR number?
Your company UTR number identifies your business as a separate entity for business tax purposes. This number will also appear in any correspondence you receive from HMRC about your business taxes.
Your company Unique Taxpayer Reference (UTR) number is an individual 10-digit number that HMRC issues to all new limited companies as a means to identify companies and allow them to pay corporation tax and file tax returns.
You will need to provide your company UTR number for the following purposes:
- Changing your corporation tax accounting period
- Paying corporation tax
- Contacting HMRC for company related issues
- Informing HMRC about changes to your registered details or company structure
- Filing tax Returns
- Informing HMRC if your business is dormant
- Registering for corporation tax, VAT, and PAYE.
Where Can I Find My Company UTR Number?
To find your UTR number, you can check any payment reminders received from HMRC, as well as your setup emails or any tax reference emails. You can also contact HMRC if necessary to receive your company’s UTR number, but be aware that you will likely need to go through strenuous security measures to do this.
If you are the director of a limited company, your individual and company UTR numbers will be different – your personal UTR for self-assessment is completely different to your company’s UTR.
It’s important to note that sole traders do not have company UTR numbers and will instead use their individual UTR number for self-assessment tax purposes.
What if I can’t find my company UTR?
If you’re starting a new limited company, HMRC will automatically issue your business with a UTR number within 4 weeks of registering as a limited company. If you have not received your UTR number within this time frame, or if you are converting from self-employment to limited company status, you can rerequest the UTR number here.
If you haven’t completed your company formation process, your company accounts won’t yet be registered for a UTR number. To receive your UTR number, you will need to register your limited company with Companies House website first, which we’ll take a look at below.
If you have lost your personal self-assessment UTR number, you can Find a Lost UTR Number on the HMRC website.
