If you are self-employed or earning income outside of PAYE (Pay As You Earn) employment in the UK, you need a Unique Taxpayer Reference (UTR) number. This 10-digit number is issued by HMRC (Her Majesty's Revenue and Customs) and is essential for filing tax returns. Applying for a UTR number can be done online, making the process more convenient and accessible. In this guide, we will cover everything you need to know about the UTR number online application, including why you need it, how to apply, and what to do if you encounter issues.
What is a UTR Number?
A UTR number is a unique identifier assigned by HMRC to individuals and businesses who need to submit Self Assessment tax returns. This number ensures that your tax records are correctly linked to your identity. Without a UTR number, you cannot file your tax return, which could lead to penalties or fines.
Who Needs a UTR Number?
You need a UTR number if you are:
Self-employed (freelancer, contractor, or sole trader)
A business owner who needs to file tax returns
A landlord earning rental income
A partner in a business partnership
Earning untaxed income, such as from investments or side gigs
If any of the above apply to you, you must complete the UTR number online application to ensure you can legally report your income to HMRC.

The UTR number online application is straightforward and can be completed in a few steps. Here’s how to do it:
