How to Get Your Tax Reference Number?

To get your tax reference number, follow these steps. This unique identifier is essential for filing your tax returns and managing your tax affairs.

Register for Self assessment: If you're self-employed or a sole trader, you must register with HMRC for self-assessment. You can do this online through the HMRC website. Once registered, you will automatically receive your tax reference number, usually within ten days.

Check Your Documents: Your tax reference number can often be found on various official documents from HMRC, including:

  • Your SA250 letter (welcome to Self Assessment)

  • Previous self-assessment tax returns

  • Payment reminders

  • Notices to file a tax return

  • Your personal tax account on the HMRC website

Contact HMRC: If you cannot find your tax reference number, you can call HMRC’s Self Assessment helpline at 0300 200 3310. Be ready to provide your personal details, including your National Insurance number.

Request by Post: If necessary, you can also write to HMRC to request your tax reference number. However, this method may take longer than online options.

Is the tax reference number the same as a unique taxpayer reference (UTR)?

The tax reference number and the Unique Taxpayer Reference (UTR) are not the same, though they are often confused. A UTR is a specific 10-digit number assigned by HM Revenue & Customs (HMRC) to individuals and businesses for tax purposes. It uniquely identifies taxpayers and is essential for filing self-assessment tax returns.

In contrast, the term tax reference number is broader and can refer to various identifiers used by HMRC, including the UTR. Other types of tax reference numbers include employer PAYE references and corporation tax references, which serve different functions within the tax system.

Understanding the difference between these numbers is crucial for managing your tax obligations effectively. Keeping your tax reference number and UTR handy will help ensure smooth communication with HMRC and facilitate accurate tax filings.

UK alternatives to a tax identification number

In the UK, while the Unique Taxpayer Reference (UTR) is the primary tax identification number, several alternatives serve similar purposes. Understanding these alternatives can help individuals and businesses manage
their tax affairs more effectively.

  • National Insurance Number (NIN): This unique number is assigned by HM Revenue & Customs (HMRC) for social security and pension purposes. It also acts as an identification number for tax matters.
  • Company Registration Number (CRN): Businesses must register with Companies House to receive a CRN. This number is essential for identifying the company in tax-related activities.
  • VAT Registration Number: If your business is VAT registered, HMRC assigns a VAT registration number. This number is crucial for identifying your business in VAT transactions.
  • Self-Assessment Registration Number: Self-employed individuals and certain partners in partnerships must register for Self assessment with HMRC, receiving a specific registration number for this purpose.

These tax reference numbers play vital roles in ensuring compliance with UK tax regulations. Familiarising yourself with these
identifiers can simplify your tax processes and enhance your business's financial management.

Using the correct HMRC number

Using the correct HM Revenue & Customs (HMRC) number when communicating with them or filing taxes is important. Each number serves a specific purpose and is used to identify the individual or business for a specific tax-related matter.

For example, if you're a self-employed individual, you would use your Unique Taxpayer Reference (UTR) when filing a self-assessment tax return and your National Insurance number when reporting your income to HMRC. On the other hand, a company would use its Company Registration Number (CRN) when filing Corporation Tax returns and its VAT registration number when submitting VAT returns.

Using the incorrect number could result in delays in processing your tax-related matters or even penalties for non-compliance. It is essential to ensure that you have the correct HMRC number and use it correctly to avoid confusion and ensure that your tax-related matters are handled efficiently.

registration number?

To register for a Unique Taxpayer Reference (UTR) number in the UK, you need to provide specific information to HM Revenue & Customs (HMRC).

Providing accurate and complete information is crucial for a smooth registration process. Once registered, you will receive your UTR number by post, which will help you file your tax returns and manage your tax obligations effectively.

When will a UTR not be issued?

A Unique Taxpayer Reference (UTR) is essential for managing your tax affairs in the UK. However, there are specific situations where HM Revenue & Customs (HMRC) may not issue a UTR. Here are some common reasons:

  • Incomplete or incorrect information: If the details you provide to HMRC are missing or incorrect, they may not process your application and issue a UTR.
  • Tax Fraud Concerns: If HMRC suspects fraudulent activity, they may withhold the issuance of a UTR to prevent potential tax evasion.
  • Non-Compliance with Tax Laws: A history of failing to comply with tax regulations, such as not filing tax returns or paying taxes, can result in HMRC refusing to issue a UTR.
  • Non-residency: You must be a resident of the UK to qualify for a UTR. Non-residents are not eligible.
