What is VAT?

9 min read

There can be a lot of jargon to sift through when it comes to running a business – from Corporation Tax to dividends, to name just a couple. One term you’ve probably heard of before is VAT, or Value Added Tax.

If you register for VAT, you may find it useful to familiarise yourself with what VAT is and what your VAT number means, so in this guide, we’ll walk you through all things VAT.

What is VAT?

VAT, or Value Added Tax, is a tax on the sale of certain goods and services. VAT has been around in the UK since 1973 when Britain entered the European Economic Community (EEC). While the UK has now left the EU VAT regime, domestic VAT rules haven’t significantly changed following Brexit, but there are now different rules around imports and exports.

How does VAT affect my business?

If you’re a VAT-registered business (more on this later) you must charge VAT on your taxable sales and report income and expenditure figures accurately in a VAT return for HMRC generally every three months. You may also be able to reclaim VAT on goods or services you’ve bought as part of your business’s operations.

Do businesses pay VAT?

VAT is intended to be an end consumer tax rather than a business tax. If you’re a VAT-registered business you must pay VAT to HMRC on the sales you make, and report the VAT amounts you’ve charged customers. You will also be charged VAT on costs you incur and may be able to recover that VAT depending on the type of cost and how it is used in your business. When pricing your sales you may need to consider your cost base and the market you are selling to.

What does VAT registered mean?

If your taxable turnover exceeds £85,000 in the previous 12 months or is expected to do so in the next 30 days, you’ll have to register for VAT. If you are trading below the VAT registration threshold you can register voluntarily. Once you’re VAT registered, you’ll have the following responsibilities:

  • you’ll need to charge customers the correct amount of VAT
  • make sure you submit VAT returns
  • pay HMRC any VAT that’s due
  • create an online VAT account where you keep VAT records – since April 2022, it has been mandatory for all VAT-registered businesses to sign up for ‘Making Tax Digital’, including those trading below the £85,000 threshold. Since 2019, VAT registered businesses trading above £85,000 have been required to file under the Making Tax Digital provisions.

So, while it’s great news if your company is growing, you’ll need to keep a watchful eye on your turnover as your tax responsibilities may increase once you’re liable for VAT.

Should I voluntarily register for VAT?

If you don’t meet the minimum turnover threshold, VAT registration isn’t compulsory, but some companies still choose to register. Here are some pros and cons of registering for VAT on a voluntary basis:


  • becoming VAT-registered means you may be able to reclaim VAT on business purchases you make
  • you may avoid fines for late registration if you happen to sneak above the £85,000 threshold one year
  • if you think you may need to eventually become VAT-registered, doing this early could save you valuable time before your business grows and you’re occupied with other matters


  • as a VAT-registered business, you’ll need to include VAT on your sales, so your products or services may seem more expensive to customers. You may need a solid pricing strategy to ensure your sales don’t dip
  • you will have a new layer of admin, such as VAT invoicing and completing your VAT return. Keeping on top of your bookkeeping may help with this
  • the extra paperwork required for VAT compliance could mean your accounting bills increase.

How to get VAT registered

You can register for VAT online to get the ball rolling; you’ll just need a Government Gateway user ID and password, which you can create if you don’t have one. Some businesses must register by post; and again, GOV.UK has all the relevant info. Once your registration has been approved, you’ll receive a VAT certificate and VAT number.

What is my VAT number?

Your VAT number is the unique ID that HMRC assigns to your business when you register for VAT. It means you can then charge VAT on your taxable sales, and report your income and expenditure figures to HMRC in a VAT return using your unique VAT number.

What does a VAT number look like?

If you’re based in the UK, your VAT number will be nine digits long and have the letters ‘GB’ at the start, such as ‘GB987654321’. And if you’re dealing with a supplier from another county, their VAT number will follow a different format with its own unique country code.

Where can I find my VAT number?

It will be confirmed on your VAT certificate, which is sent to your Government Gateway account once you’ve registered for VAT. For easy reference, you can put your VAT number on your invoices. Alongside the details of your business, such as your company name and address.

How long does it take to get a VAT number?

After you’ve registered for VAT, your VAT number could be delivered to you within as little as 30 working days, either via your VAT online account or by post if you are unable to register online, or an agent has registered you. However, if HMRC needs to carry out extensive checks on the applicant, the process can take longer.

How do you find a business’s VAT number?

VAT numbers are publicly available in the UK. You can check a Company Registration on the Companies House website, but if you’re dealing with a VAT-registered Sole Trader you may only be able to find their VAT number on an invoice.

Is a VAT number and EORI the same thing?

An EORI number is a unique 12-digit ID code given to businesses that import or export goods into or out of the EU and will need to be quoted on various forms. This isn’t the same thing as a VAT number – however, if you are VAT registered, then they can be linked. When you submit your VAT registration, you will be given an option to also register for an EORI number. Once that’s all done, HMRC are able to link all your imports to your VAT number.

Is a VAT number the same as a tax ID?

No – a ‘tax ID’ is not the same as a VAT number. In the UK, there is the unique taxpayer reference (UTR) which is a ten-digit number allocated to individuals who need to complete a tax return, such as limited company directors or sole traders. There is also a National Insurance Number (NINO), which makes sure your National Insurance contributions are correctly recorded against your name. By contrast, a VAT number is always allocated to VAT-registered companies, rather than individuals.

Is a VAT number the same as an EIN number?

A VAT number isn’t the same as an Employer Identification Number (EIN), which is a term used in the United States to identify businesses for the purposes of tax reporting. Perhaps the closest comparison in the UK is the company registration number obtained through Companies House when you set up a business and apply for a certificate of incorporation.

Do I need to be VAT registered if self-employed?

Every UK business needs to register for VAT once their sales exceed £85,000 per year, and that includes self-employed business owners. Sometimes, a group of eligible people, such as a business partnership, may be treated as a single taxable person for VAT purposes – read more on GOV.UK.

When should I start charging VAT?

The date you register for VAT is also the date you should start charging VAT, rather than waiting for your VAT number on your certificate. To add to the complexity, you’re not allowed to issue VAT invoices until your certificate arrives, even if you’re registered. Once you have your VAT number, you must send out VAT invoices to your VAT-registered customers.

What are the VAT rates?

Once you’ve determined you’ll need to register for VAT, what VAT rate will you pay? Here’s a quick summary of the VAT rates for different goods and services:

VAT rate

When VAT is chargeable

Standard rate


The majority of goods and services

Reduced rate


Certain goods and services, like domestic fuel

Zero rate


Qualifying goods and services, such as most food

Let’s look at some examples of when VAT is applicable and when it’s not.

Most food and drink incurs zero VAT, but there are exceptions, such as alcohol, confectionary, sports drinks and hot food, which are taxed at the standard VAT rate. Those with memories of the abandoned ‘pasty tax’ proposal will remember that pasties, pies and sausage rolls can be VAT-free, as although the food has been heated in an oven, it’s not being ‘kept warm’ at the point of sale.

Sales of donated goods at charity shops are zero-rated for VAT, while services like electricity incur the reduced 5% rate for domestic use, but the standard rate for businesses. Read more about different VAT rates on goods and services.

How is VAT calculated?

Luckily, you don’t have to be a mathematician to know how to calculate VAT, and here’s a simple formula for working out your VAT breakdown:

  1. Assuming it’s a VAT rate of 20%, to work out the VAT amount in a price including VAT, divide the VAT inclusive price by 120 (for a 5% rate, divide by 105).
  2. To calculate the pre-VAT total, multiply your result by 100.
  3. To work out the VAT amount, multiply the result from step one by 20 for a 20% rate, or by 5 for 5%.

There are other ways VAT can be calculated and GOV.UK has more number crunching suggestions.

How to pay VAT

You generally need to pay VAT to HMRC every three months, which is your VAT accounting period. You can pay your VAT online, by standing order or Direct Debit, but not over the phone. It’s your responsibility to submit your VAT return with accurate records, and confirmation of the amount you owe. The return must be submitted with any tax payable by the due date.

How to reclaim VAT

You can usually reclaim the VAT you pay for items you’ve purchased for business purposes although some business may be subject to more restrictive recovery. Sometimes, you may be able to claim a proportion of expenditure; for example, a percentage of a mobile phone bill which is partially used for work purposes. When you submit a VAT return you can make your claim for a refund. Find out more about how to reclaim VAT.
