A Guide to Unique Taxpayer Reference (UTR) numbers

Finding Your UTR Number

If you're on the hunt for your Unique Taxpayer Reference (UTR) number, it's a key identifier HMRC uses for your tax records. Here’s where you can locate it:

- Welcome Letter: When you first register for Self Assessment, you'll get a 'welcome to Self Assessment' letter (SA250) from HMRC.
- Tax Documents: Your UTR will be on your previous tax returns and any other official correspondence from HMRC, such as payment reminders or your annual statement.
- Online: Log into your personal tax account on the HMRC website or use the HMRC app.
- Notice to File: If you've received a notice to file a tax return, your UTR will be there too.

Lost Your UTR Number?

If your UTR number has gone AWOL, don't worry. Before you contact HMRC, double-check all documents mentioned. If it's still MIA, HMRC is just a call away. Remember, safeguard your UTR to prevent identity theft.

- Phone HMRC: Dial 0300 200 3310 to discuss your UTR needs. Be ready with personal details and your National Insurance number.

Registering for a UTR

You get on HMRC’s radar for a UTR once you register for self-assessment or start a limited company. Do it online or post a completed form to HMRC. They expect this within the first three months of your business’s life. Wait for an activation code in the post, then set up your online tax account.

Information for UTR Registration

Have these details handy:

- Personal information (name, date of birth, address)
- National Insurance number
- Contact details
- Self-employment start date
- Business details (address, type)

UTR for Companies

HMRC also assigns every limited company a UTR, which is necessary for tax obligations. It comes your way when registering your company and is found on official HMRC correspondence, such as the CT603 form.

Keep this number secure and accessible for future tax-related tasks.
