VAT Registration number in the UK: a comprehensive guide

Businesses in the UK with a turnover of over £90,000 are legally required to register for VAT, and are issued a VAT Registration Number (VRN). Companies can also voluntarily register for a VRN if they want. But what does VAT registration mean for your business? ANNA is here to help explain what becoming registered for VAT means for you. 

What is a VAT number?

A business's VAT number is used to track and report their VAT obligations to the tax authorities – in the UK, that’s HMRC.

VAT Number structure

UK VAT numbers follow a specific structure, consisting of nine digits, starting with the prefix "GB" for the UK, GB123456789 for example. The first two letters denote the country, while the subsequent numbers are unique to the business.

European countries follow similar patterns, such as "DE" for Germany or "FR" for France. The following numbers can be longer or shorter.

Why do I need a VAT registration number (VRN)?

A VRN is a legal requirement for businesses that meet the VAT threshold. Once you’ve registered, you can (and must) charge VAT on most goods and services. It also allows businesses to reclaim VAT on purchases, while still staying compliant with HMRC regulations.

Get familiar with your VAT number, because showing your VAT number on invoices, receipts, and other business documents is mandatory. It also has to be on display on your website and any other kind of public communication, such as marketing materials.

You’ll use your VAT registration number in a range of situations, including issuing invoices to clients, filing VAT returns with HMRC, and when you claim VAT back on goods or services you’ve bought for your business. It’s also necessary for customers and suppliers to verify your VAT status.

Where can I find my VAT number?

To find your VAT number, you can check your VAT registration certificate, which HMRC provides once you complete the registration process. You can also call the HMRC VAT helpline on 0300 200 3700.

Registering for a VAT number

To get a VAT number, you must register your business for VAT with HMRC. You can do this online through the HMRC VAT registration portal.

When you can't register online

In some cases, such as joining the Agricultural Flat Rate Scheme or registering a division of a corporate body, you may need to register using a paper form instead of the online system.

Verifying a VAT number

To verify a UK VAT number, you can use HMRC's VAT number verification service.

Just enter the VAT number into the HMRC tool to confirm its validity, which helps you to know whether your trading partners are VAT-registered, which protects you against fraud and ensures you’re complying with the rules.

Differences between VAT numbers and other registration numbers

When you’re running a business, there are lots of different registration numbers and it’s easy to get them confused. VAT numbers are distinct from other business identifiers like Company Registration numbers (CRN) and Unique Taxpayer Reference (UTR) numbers. A company registration number, issued by Companies House upon incorporation, is used to identify a business legally, whereas a VAT number is provided by HMRC specifically for tax purposes related to Value Added Tax. Similarly, a UTR number, assigned by HMRC, is used for income tax purposes and has nothing to do with VAT. Each of these numbers has a unique purpose and shouldn’t be confused with one another.

Obligations associated with VAT numbers

Having a VAT registration number comes with responsibilities. You need to: 

If you don't follow the regulations, you can be hit with penalties, fines, or interest charges.

If that all sounds complicated, remember that you can simplify your tax responsibilities by using a business account or tax service like ANNA. You’ll get reminders of all your deadlines, and you can even file your VAT from within the app.

Use your VAT number when issuing invoices, filing VAT returns, and in any VAT-related correspondence with customers, suppliers, or HMRC.

It typically takes up to 30 days to receive your VAT registration certificate after applying, although it can sometimes take longer.

What are the consequences of not registering for a VAT number?

Failing to register when required can result in penalties based on the amount of VAT owed and the length of the delay. HMRC may also charge interest on unpaid VAT.

Can I check a VAT number online?

Yes, you can verify VAT numbers online using HMRC's VAT number checker or the EU's VIES system for EU VAT numbers.

Does the VAT number format differ between countries?

Yes, each country has its own VAT number format, usually starting with a country code followed by a series of digits or characters unique to that country.

How do I update my business details for my VAT registration?

You can update your details through your HMRC online account or by informing HMRC directly if certain changes occur, such as a change in business address or legal structure.

Can an individual have a VAT number, or is it only for businesses?
