VAT in the UK can look simple on a receipt: a percentage added to the price of a product or service. Behind that figure is a tax system with different rates, exemptions, registration rules and a history stretching back more than 50 years.
For consumers, VAT is usually something seen at the checkout. For businesses, it can become a major part of accounting and reporting.
What Is VAT in the UK?
VAT stands for Value Added Tax. It is a consumption tax charged on many goods and services sold by VAT-registered businesses.
HM Revenue & Customs confirms that VAT was introduced in the UK on 1 April 1973. The tax was created under the Finance Act 1972, replacing the previous purchase-tax arrangements.
The basic principle has remained familiar. Businesses charge VAT on applicable sales and account for the tax through HMRC. A VAT-registered business can generally recover eligible VAT paid on business purchases, subject to the relevant rules.
What Is the VAT Rate in the UK?
The standard VAT rate is currently 20%.
HMRC also recognises a reduced rate of 5% and a zero rate of 0%. Which rate applies depends on the specific product or service and, in some cases, how it is used.
Most goods and services fall under the 20% standard rate. Examples of reduced-rate treatment include certain domestic fuel and power supplies, while many basic food products and children’s clothing are examples of goods that can be zero-rated.
Zero-rated does not mean the same thing as exempt. A zero-rated supply is still within the VAT system but is charged at 0%. Exempt supplies are treated differently under VAT rules.
When Was VAT Introduced in Britain?
The history of VAT provides one of the clearest clues to how the present system developed.
VAT began in the UK on 1 April 1973 at a standard rate of 10%. The rate subsequently changed several times. HMRC records show that it reached 15% in 1979, 17.5% in 1991, temporarily fell to 15% in December 2008, returned to 17.5% in January 2010 and then increased to 20% on 4 January 2011.
The 20% standard rate has remained in place since that 2011 increase.
There is therefore no mystery about when the current standard rate began. It has been 20% since January 2011, rather than being a recent introduction.
Who Has to Register for VAT?
This is where VAT becomes particularly important for businesses.
According to current GOV.UK guidance, a business generally must register when its taxable turnover for the previous 12 months goes above £90,000, or when it expects its taxable turnover to exceed £90,000 during the next 30 days.
The £90,000 figure is the current registration threshold for 2026. The government’s 2026–27 tax rates document confirms that the threshold remains £90,000, while the deregistration threshold is £88,000.
A business below the threshold can also choose voluntary VAT registration. That decision has consequences, including VAT charging and reporting responsibilities, so it is not simply a matter of adding 20% to invoices.
How Does VAT Work for a Registered Business?
Once registered, a business normally charges the appropriate VAT rate on taxable sales.
It must keep records of VAT paid on eligible purchases, report VAT through VAT returns and pay the amount due to HMRC. GOV.UK explains that the amount normally owed is based on the difference between VAT charged to customers and eligible VAT paid to other businesses.
For example, a business might collect £2,000 in VAT from customers during an accounting period while having £700 of eligible VAT on business purchases. Subject to the applicable rules, the difference would be £1,300.
The actual calculation can be more complicated where different VAT rates, exemptions, imports, reverse charges or special schemes are involved.
Why Are Some Products Not Charged at 20%?
This is one of the areas that often causes confusion.
The UK does not apply one universal VAT rate to every purchase. Some goods and services are zero-rated or reduced-rated, while others are exempt.
GOV.UK lists examples of zero-rated supplies including books and newspapers, children’s clothes and shoes, and many exports. Reduced-rate VAT can apply to specific goods and services such as some domestic energy supplies.
The precise treatment can depend on the circumstances. Assuming that a product is zero-rated simply because it appears similar to another zero-rated product can therefore lead to an incorrect VAT calculation.
VAT in the UK Today
The basic facts are straightforward. VAT has existed in the UK since 1973, the standard rate is currently 20%, and businesses generally have to register once taxable turnover exceeds £90,000 under the current rules.
But the details matter. VAT treatment depends on the goods or services involved, the circumstances of the transaction and whether a particular exemption or reduced or zero rate applies.
For anyone trying to understand VAT in the UK, the most important distinction is between the headline 20% rate and the much wider system behind it. The percentage on a receipt is only the visible part of the story.
