Where Can I Find My UTR Code?
A straightforward guide to tracking down your Unique Taxpayer Reference for HMRC filings.
What Is a UTR Number?
A Unique Taxpayer Reference (UTR) is a 10-digit number issued by HMRC to every individual and company that needs to file a tax return. It's your personal or business identifier within the UK tax system, and you'll need it whenever you correspond with HMRC, file a Self Assessment return, or submit a Company Tax Return.
As accountants in Brentwood, one of the most common questions we're asked by new clients is where to find their UTR. Select your type below to see how to find yours.

Common Questions
What is a UTR number and why do I need one?
A Unique Taxpayer Reference (UTR) is a 10-digit number issued by HMRC. You need it to file Self Assessment tax returns, submit Corporation Tax returns, and communicate with HMRC about your tax affairs.
Where can I find my UTR number?
Your UTR appears on previous tax returns, HMRC correspondence, your Personal Tax Account online, or the original letter HMRC sent when you registered for Self Assessment. Your accountant will also have it on file.
I've lost my UTR — how do I get a new one?
You don't need a new one — your UTR stays the same. You can recover it by logging into your HMRC Personal Tax Account, calling HMRC's Self Assessment helpline, or asking your accountant to look it up for you.
Is my company UTR the same as my personal UTR?
No. If you're a company director, you'll have a personal UTR for your Self Assessment and a separate company UTR for Corporation Tax. They are different numbers used for different purposes.
