3. How to Find Your UTR on HMRC Correspondence
As well as being able to find your UTR number online, you’ll find it on any correspondence you have from HMRC. They use your tax reference number as a way to identify you on their systems to access your personal information. HMRC will always use it as a reference on the letters they send to you.

- HMRC Statement of Account;
- Payment Reminders or Late Payment Letters;
- Your SA250 which is a letter issued by HMRC when you first registered as self-employed.
4. How to Find Your Unique Taxpayer Reference By Phone
If you are struggling to find your UTR number online, then your best bet is to call HMRC on 0300 200 3310. You can then request your unique taxpayer reference number over the phone. Remember, when you call HMRC you’ll need to confirm your identity so you’ll need your National Insurance number in addition to your personal details.
Given the confidential nature of your UTR, HMRC will need to send it out to you by post. Therefore, you should be aware that it can take up to 7 days to arrive.
5. Sharing Your Unique Taxpayer Reference (UTR)
Your UTR number is a highly confidential piece of information so you should never share it unless you’re certain it’s for the right reasons. For example:
- You are a CIS subcontractor and your contractor has requested it to confirm how much tax they should withhold, although you’ll get credit for any tax on your CIS tax return;
- They are a professional, such as an accountant with the authority to act on your behalf.
If you are unsure whether your UTR number is valid or you need to check it, then always contact HMRC first on 0300 200 3310.
6. How Can I Check a Tax Reference Number?
You can check your own UTR number by calling HMRC on 0300 200 3310 or by going online. UTR numbers are highly confidential since they are used by HMRC as part of the identification process when accessing information about an individuals taxes. If you are a CIS contractor and need to check a UTR number, then you’ll need to verify subcontractors by:
7. Is My HMRC UTR Number Still Active?
As long as you have not de-registered as self-employed it will still be active. It’s good for you to know that it will last for as long as you remain registered as self-employed.
8. Can I Reactivate an Old Unique Taxpayers Reference?
No, a UTR cannot be reactivated. Say you decided to go self-employed and then deregistered because you went back into full-time employment. If you decided you wanted to go back to self-employment you’ll have to register as a sole trader again and wait for HMRC to send you a new code.
If you had not deregistered and continued to submit a tax return while you were employed, you’ll won’t need to ask for a new UTR number. You’ll then need to declare any new self-employment earnings when you fill in your next tax return.
9. Where Do I Find My Limited Company UTR Number?
Your limited company UTR is different from your personal one. So if you have been asked for this reference and have a Limited Company you should clarify which one is required before you give it to anyone. You’ll find your Limited Company reference on all Corporation Tax letters sent to you by HMRC.
If you cannot find it, call the HMRC Corporation Tax Return helpline on 0300 200 3410.
10. What Happens if You’re Self-Employed and Receive Two UTR Numbers
If you have received two different tax reference numbers then you must contact HMRC quickly. HMRC will think you are two separate people! You should only ever have one code otherwise HMRC will expect more than one tax return and if you fail to send both in you’ll be issued with an automatic penalty. You’ll be able to appeal but there is no guarantee that HMRC will squash the charge. So, if you have more than one call the HMRC helpline on 0300 200 3310 as soon as possible to avoid any problems later on.
Taxes are changing! From April 2024 sole traders will need to report their earnings and pay tax on a quarterly basis. This is known as Making Tax Digital, which you can read more about in this guide to help you get prepared.
