Tax Reference Number UK: Decoding Everything About It

Living and earning in the UK exposes you to the various tax payment responsibilities, which need to be tracked for accuracy. This is where the tax reference number plays its role. It is an important element in the UK tax system for the management of tax payments. 

Although the tax reference number UK has become a complex term due to the existence of multiple identical taxation terms, like Unique Taxpayer Reference  (UTR) Number, Taxpayer Identification Number (TIN), etc., understanding its different aspects is necessary for taxpayers. 

So, let’s move ahead and understand the importance of a tax reference number, where to find it, and how it is different from UTR and national insurance numbers. 

What is Tax Reference Number in the UK?

A tax reference number is a unique identification number assigned to taxpayers to keep track of transactions. It is popularly known as a PAYE reference, Unique Taxpayer Reference (UTR), Taxpayer Identification Number (TIN), or employer reference number. HMRC assigns it to a business employer under the UK tax system. 

The tax reference number consists of a specific combination of numbers and letters, which is divided into two parts. For example, 123/AZ3004. The first three digits (for instance, 123) refer to the specific HMRC department managing PAYE matters, also known as the tax office number. Whereas, the numbers written after the slash (for instance, AZ3004) are actual reference numbers assigned to the employer by the tax office.

Moreover, as a crucial part of corporate accounting, it manages tax reductions, compliance, and regulations, ensuring timely tax payments to the government.

Types of Tax Reference Number

In general, the employer tax reference number is used interchangeably with different types of tax reference numbers. So, here is a brief introduction to all the types.

• Value Added Tax (VAT) Number: A VAT number is an identifier used for tax purposes and is only assigned to businesses registered for VAT. It allows authorities to monitor the flow of goods and the taxation of businesses.

• Social Security Number (SSN): SSN assists tax authorities in recording your earnings and determining your eligibility for social security benefits and other government services. Monetary institutions such as banks and credit card companies also ask for an SSN when opening an account. 

• Unique Taxpayer Reference (UTR) Number:  A UTR is a 10-digit unique number issued by HMRC to individuals, partnerships, businesses, and companies to allow them to file self-assessment tax returns. 

• Taxpayer Identification Number (TIN): The taxpayer identification number is an 11-digit unique number allotted to both businesses and individuals. In the US, the Internal Revenue Service (IRS) assigns this TIN.

• Employer Identification Number (EIN): An employer’s unique identification number is provided to the company so the Internal Revenue Service can quickly identify it. Moreover, EINs are often needed while reporting income tax.

• National Insurance Number (NINO): A NINO is again a unique identification number used in the UK to ensure that taxpayers’ tax and NIC are recorded in their names only. This identifier is written as a combination of two letters and six digits, for example, AZ122121L.

Knowing about the functions of each term is essential to making use of every number accurately and effectively.
