Finding your UTR number isn’t as complicated as it sounds once you know where to look. Whether you're chasing down a tax payment, double-checking a bank transfer, or wrestling with a tax return, this 10-digit code follows you everywhere. Here’s exactly where to dig it up in 2026, plus some handy tricks for when things get tricky.
Quick Fix Summary: Your UTR is a 10-digit code hiding in plain sight—your HMRC Self Assessment account, payslip, or tax return. If you’ve filed online, poke around your HMRC dashboard under "Tax Returns" or "View Account." Bank transfers usually label it as "UTR" or "Transaction ID."
What Is a UTR Number?
A Unique Taxpayer Reference (UTR) is basically HMRC’s way of giving you a permanent tax fingerprint. This 10-digit code pops up across every HMRC service—Self Assessment, PAYE, VAT—you name it. Think of it as your financial ID card; it never expires, even if you switch jobs or move house.
Here’s the catch: a UTR isn’t the same as your bank’s transaction reference, though they sometimes show up together. Picture this: you’re paying a tax bill online. Your UTR links to the bank-generated transaction reference, but they’re two different things.
Where to Find Your UTR Number
1. Online via Your HMRC Self Assessment Account
If you’ve ever filed a Self Assessment return, your UTR is staring you in the face inside your HMRC online account.
- Head to the HMRC Self Assessment login page.
- Sign in with your Government Gateway ID and password.
- Go to Self Assessment > Tax Returns > View Account.
- Your UTR sits at the top under "Your details."
2. On Your Payslip or P60
Got a PAYE income? Your UTR might be tucked away on your payslip or P60, usually under "Tax Reference" or "UTR."
- Scan the "Tax Code" or "PAYE Reference" sections.
- If it’s nowhere to be found, check your P45 when you leave a job.
3. In Your Self Assessment Tax Return
Every tax return you submit has your UTR on the first page. Saved a PDF? Search for "UTR" and it’ll pop right out.
4. In Your HMRC Correspondence
Any letter from HMRC—Self Assessment, VAT, tax credits—will have your UTR near the top, usually in a box labeled "Unique Taxpayer Reference."
5. For Freelancers or Self-Employed Individuals
Just registered as self-employed? HMRC mails your UTR within 10 working days. If you’re overseas, expect it in up to 21 days Source: GOV.UK.
