What Is Tax Office Reference Number in the UK and How to Find It?

Understanding the Tax Office Reference Number

Navigating the complexities of the UK tax system can be challenging, especially when it comes to understanding the various numbers and identifiers used. One such identifier, the Tax Office Reference Number, plays a crucial role in the interaction between taxpayers, employers, and His Majesty's Revenue and Customs (HMRC). This article delves into the essence of the Tax Office Reference Number, its significance, and how you can find it.

What Is Tax Office Reference Number in the UK and How to Find It

What is a Tax Office Reference Number?

The Tax Office Reference Number is a unique identifier assigned by HMRC to each employer or pension provider. It is crucial for managing payroll taxes under the Pay As You Earn (PAYE) system. Employers use this number to deduct National Insurance and income tax from employees' paychecks and to communicate with HMRC about these deductions.

This number varies from other identifiers, such as the National Insurance number or the Unique Taxpayer Reference (UTR), each serving different purposes within the UK tax system. For example, the National Insurance number identifies individuals for social security purposes, while the UTR is specific to individuals' personal tax affairs, particularly those involved in self-assessment tax returns​​​.

Where to Find Your Tax Office Reference Number

Discovering your Tax Office Reference Number can be straightforward if you know where to look. Typically, it can be found on:

  • Payslips provided by your employer.

  • The P45 form, given when you leave an employer.

  • Your P60 document, which summarizes your pay and taxes over the tax year.

  • Any communications from HMRC, such as the Notice of Coding.

  • Employer's Welcome Pack: Upon registering as an employer, HMRC sends a welcome pack that includes the Employer PAYE Reference Number. This is particularly relevant for business owners or those managing payroll, as it's necessary for completing year-end PAYE returns and accessing tax codes​.

  • Notice of Coding: Issued annually for every employment or occupational pension you have, the Notice of Coding details your personal tax-free allowances for the year and how they're allocated across employments. This document can contain important reference numbers related to your tax affairs​​​.

  • Account Office Reference Number: Alongside the Employer PAYE Reference Number, HMRC issues an Account Office Reference Number, a 13-digit number needed when making PAYE payments to HMRC. It's distinct from your Employer Reference Number and is critical for ensuring payments are correctly applied to your account​.

  • VAT Registration Number: For businesses registered for VAT, the VAT Registration Number is a unique identifier issued by HMRC. This number is found on VAT reports, certificates, and must be displayed on VAT invoices. It's essential for VAT-related transactions and claims​.

  • Unique Taxpayer Reference (UTR) Number: If you're registered for UK self-assessment, you can find your UTR number online by logging into your Government Gateway account, where you manage your taxes. The UTR number can be found within the self-assessment section or the top right-hand corner of your account summary. Additionally, the HMRC app provides access to your UTR number along with other tax-related information​.

  • Employer Reference Number (ERN) and HMRC Reference Numbers: For employers or those dealing with payroll, the ERN is used for payroll submissions to HMRC and is unique to each employer. Individuals will need their HMRC Reference Number for various tax-related communications with HMRC. While the article does not specify finding these numbers online directly, maintaining access to your Government Gateway account, where you can manage various tax affairs and communicate with HMRC, is crucial. For any lost or unknown numbers, contacting HMRC directly is recommended to retrieve or confirm these details

Each of these identifiers serves a specific function within the UK tax system, highlighting the complexity and the need for accurate record-keeping. Whether you're an employer, employee, or running your own business, knowing where to find and how to use these numbers is crucial for effective tax management and compliance.

Each employer has a unique tax reference number; hence, if you work for multiple employers, you will have multiple reference numbers. This number is essential for identifying your tax records with HMRC and is required when making enquiries related to your tax details​​​.

The Difference Between Tax Reference Numbers and UTR

It's important to distinguish between your Tax Office Reference Number and other tax identifiers like the UTR. The UTR is issued to individuals who need to manage their taxes through self-assessment, such as the self-employed or those with complex tax situations. Unlike the employer-specific Tax Office Reference Number, a UTR is unique to the individual taxpayer and remains constant throughout their dealings with HMRC​​​.

How to Obtain or Retrieve Your Number

If you're unable to find your Tax Office Reference Number or UTR, there are steps you can take to retrieve it:

  • For the Tax Office Reference Number, check your payslips, P60, or P45 forms first. If still unresolved, your employer should be able to provide it.

  • For a UTR, if you've previously registered for self-assessment or have a limited company, it should be on past tax returns or official HMRC documents. If you can't find it, contacting HMRC directly is the best course of action. They can resend the information, usually through the post, which may take up to 10 days​.

Understanding and utilizing your Tax Office Reference Number and UTR is vital for managing your tax affairs in the UK efficiently. These identifiers allow for accurate tax reporting and compliance, facilitating smooth communication with HMRC. Knowing where to find these numbers and how they differ from each other ensures that you can navigate the tax system more effectively, whether you're an employee, self-employed, or running a business.

Employers must periodically review their PAYE systems to ensure that the correct Tax Office Reference Number is used in all submissions.
