How to Find Your UTR Number?

Updated: Jun 7


Understanding UTR Numbers and Their Importance

In the United Kingdom, the Unique Taxpayer Reference (UTR) number is a critical element in the tax system. It's a 10-digit number assigned by HM Revenue and Customs (HMRC) to individuals and entities to uniquely identify them for tax purposes. This number becomes particularly important when you need to file a Self Assessment tax return, which is mandatory for various categories of taxpayers.


How to Find Your UTR Number

What Does UTR Number Look Like?

A Unique Taxpayer Reference (UTR) number in the UK is a 10-digit code used to identify individuals and companies for tax purposes. This number is issued by HM Revenue and Customs (HMRC) and is unique to each taxpayer. It typically looks like this:


It's important to note that while the format remains consistent (ten digits), the specific numbers will vary for each individual or entity. The UTR number is a crucial piece of information for tax filing and communication with HMRC, especially for those who need to complete a Self Assessment tax return.


Who Needs a UTR Number?


The need for a UTR number is not universal for every UK taxpayer. It's specifically required for those who must complete a Self Assessment tax return. This includes:

  1. Self-Employed Individuals and Sole Traders: If you are self-employed, running your own business, you are responsible for calculating and declaring your own taxes. A UTR number is essential for this process.

  2. Partners or Members of a Limited Company: Those who own or are partners in a registered UK company need a UTR number to file their tax returns.

  3. People with Side Hustles or Additional Untaxed Income: If you have income sources not automatically taxed, such as earnings from freelance work, renting out property, or other side hustles, you will need to register with HMRC and obtain a UTR number.

  4. Students Working in the UK: If you are a student earning an income, you are also required to pay taxes and may need a UTR number.


How to Obtain a UTR Number


Obtaining a UTR number is a straightforward process, primarily done through the HMRC website. There are three main methods:

  1. Online Registration: This is the most common method. You visit the HMRC website, fill in the necessary details and get yourself registered for Self-Assessment, and your UTR number is sent to you by post within 10 days, or contact their Online Help Desk.

  2. By Post: For those who prefer or need to register by post, this option is available but might take longer due to the postal process.

  3. By Phone: You can also apply for a UTR number over the phone through the self-assessment hotline. However, you may still be directed to complete the process online.

  • Telephone:0300 200 3310

  • Outside UK:+44 161 931 9070

  • Opening times: Monday to Friday: 8am to 6pm (Closed on weekends and bank holidays.)


Required Information for UTR Application

When applying for a UTR number, you need to provide personal information such as your full name, current address, phone number, email address, date of birth, and National Insurance number. If you’re applying as a business or for a side hustle, additional details like business phone number, type of business, business address, and start date of self-employment will be required.


In this first part, we have explored the basics of UTR numbers, who needs them, and how to obtain one. This foundational understanding is crucial for anyone involved in the UK tax system, particularly for those who are self-employed, have additional untaxed income, or are involved in a partnership or limited company. In the next part, we will delve into how to find your UTR number and what to do if you lose it.


What Different Situations You May Have to Face If You Have Lost Your UTR

In the United Kingdom, your Unique Taxpayer Reference (UTR) number is a vital component of managing your tax affairs, especially if you are self-employed, a member of a partnership, or run a limited company. Losing this number can lead to various challenges and complications. This article explores different scenarios you might face without your UTR number and how to navigate these situations.


1. Difficulty in Filing Self-Assessment Tax Returns

Without your UTR number, filing your Self-Assessment tax returns becomes a significant challenge. The UTR is essential for identifying your tax records with HM Revenue and Customs (HMRC). Without it, you cannot submit your returns online or via post, leading to potential delays and even penalties for late submission.


2. Complications in Paying Taxes

Paying your taxes, whether income tax, capital gains tax, or corporation tax, requires your UTR number for proper allocation of your payments. Losing this number can cause payments to be incorrectly processed, leading to confusion and potential issues with your tax account.


3. Problems with Tax Refunds or Adjustments

If you're due a tax refund or need to make adjustments to previous tax returns, your UTR number is crucial. Without it, HMRC might not be able to process your refund or adjustments accurately, which could delay receiving any amounts owed to you.


4. Hurdles in Communicating with HMRC

Communicating with HMRC about any aspect of your taxes typically requires your UTR number. Without it, verifying your identity and discussing your tax affairs can be more complex and time-consuming.


5. Challenges in Accessing Financial Services

Many financial services, such as applying for loans or mortgages, especially for self-employed individuals, require proof of earnings through tax returns. Your UTR number is needed to access these records, and without it, you may face delays or difficulties in securing financial products.


6. Impact on Business Operations

For business owners, a lost UTR number can impede various operations. It's necessary for completing corporation tax returns, VAT returns, and dealing with payroll taxes under the PAYE system. The absence of a UTR number can disrupt these processes and affect your business's compliance with tax regulations.


7. Delays in Setting Up Payment Plans

If you owe taxes and need to set up a payment plan with HMRC, your UTR number is required. Without it, there might be delays in arranging a suitable payment plan, potentially leading to increased interest or penalties.


8. Issues with Tax Advisors or Accountants

Working with tax advisors or accountants is streamlined when you have your UTR number readily available. Losing this number can make it more challenging for them to assist you efficiently, potentially leading to delays in managing your tax affairs.


9. Problems with Legal and Business Transactions

Certain legal and business transactions require tax information, including your UTR number. For instance, if you're selling a business or part of a business, your UTR number is necessary for the process.


10. Difficulties in Claiming Expenses and Reliefs

Claiming for various tax reliefs and expenses, especially if you are self-employed or run a business, requires your tax records, accessed using your UTR number. Not having this number might complicate the process of claiming these reliefs.


Losing your UTR number can lead to a range of challenging situations, affecting everything from tax filing to business operations. It's crucial to keep your UTR number secure and accessible. However, if you do lose it, contact HMRC as soon as possible to retrieve it. The process might take some time, but regaining your UTR number is essential for maintaining smooth tax affairs and avoiding potential complications in the UK tax system.
