Value Added Tax (VAT) is one of the UK Government's largest sources of tax revenue, and almost every trading business will encounter it as turnover grows. In this guide, we provide a practical overview of VAT in the United Kingdom. We explain how it works, who must register with HM Revenue & Customs (HMRC), and the rates for 2026.

VAT is a consumption tax levied on goods and services, known as Goods and Services Tax (GST) in some countries. VAT-registered businesses generally charge VAT on taxable sales, reclaim eligible input VAT and pay the difference to HMRC, subject to restrictions and special schemes. The final consumer generally bears the VAT cost, although businesses can also bear VAT they cannot reclaim.

The stakes are real. Registration becomes compulsory once taxable turnover passes £90,000, and the rules on deadlines, returns and penalties catch out many newly trading companies. Knowing the system in advance is far cheaper than untangling it afterwards.

How Does VAT in the United Kingdom Work?

VAT is charged on taxable supplies at each stage of the supply chain. VAT-registered businesses generally charge VAT on taxable sales and can reclaim eligible VAT on business purchases, subject to restrictions.

From raw materials and early production through to the final sale, VAT is levied on taxable supplies at each stage. The seller charges VAT to the buyer, then pays the tax over to HMRC. A buyer that is not the final consumer, such as a manufacturer purchasing components, charges VAT when it sells the finished product. It can generally reclaim the VAT it paid on its inputs, subject to restrictions.

A VAT-registered seller accounts for output VAT on taxable sales and can generally reclaim eligible input VAT on business purchases, subject to restrictions and special schemes. VAT is expressed as a percentage of the price. If a device costs £100 before VAT, 20% VAT makes the selling price £120. The seller receives the £100 price and accounts for £20 VAT to HMRC, subject to input-tax deductions.

The VAT a business pays on its own purchases is its input tax; the VAT it charges on its sales is its output tax. A standard VAT return reconciles output tax and eligible input tax, while special schemes use different calculations, so accurate record-keeping matters from day one.

What Is the Difference Between VAT and Sales Tax?

Sales tax is charged once, at the final point of sale, while VAT is collected at every link in the supply chain.

The main difference between VAT and sales tax lies in the supply chain. Sales tax applies at the end of the chain. The end user pays the tax to the seller, as when paying sales tax to a retailer after buying clothes.

VAT, on the other hand, charges tax along the supply chain. Every time a product or service gains value and passes to another supplier, distributor or retailer, the seller collects VAT. The regime does not only tax the purchaser at the final point of sale; the tax is collected throughout the process.

The distinction matters for businesses comparing markets. Our guide to doing business in the United Kingdom vs USA examines how the tax systems, formation costs and compliance duties of the two countries differ.

When Must You Register for VAT in the UK?

Registration is generally compulsory once taxable turnover exceeds £90,000 in a rolling 12-month period, and HMRC must be notified within 30 days of the end of the month in which the threshold is crossed.

You generally must register for VAT if your taxable turnover exceeds £90,000 over the last 12 months, unless HMRC grants an exception or exemption. Register within 30 days of the end of the month when you crossed the threshold. The £90,000 level has applied since 1 April 2024, and HMRC publishes the current rules on GOV.UK. For this test, your effective registration date is the first day of the second month after crossing the threshold.

You must also register if you expect taxable turnover to exceed £90,000 in the next 30 days. Register by the end of that period. Your effective date is when you realised you would exceed the threshold. Separate rules apply if you and your business are based outside the UK. An overseas business generally must register regardless of turnover if it makes taxable supplies in the UK or expects to do so within 30 days, subject to exceptions such as the reverse charge.

Voluntary registration below the threshold is also possible, and it can make sense where the input tax on start-up costs is significant. It brings filing obligations with it, so the decision should be made on the numbers rather than by default. Businesses can generally apply to deregister if expected taxable turnover over the next 12 months is below £88,000. This test looks forward, not back at a rolling past period. Separate rules apply to some overseas businesses.

If you register late, you must account for VAT on taxable sales since the date you should have registered. You may also face a penalty based on the amount owed and the length of the delay. Late registration is just one of many pitfalls, so it is worth learning how to avoid common VAT errors in the United Kingdom before they cost you money. Checking your rolling 12-month turnover every month keeps the notification window from being missed.

What Are the Current VAT Rates in the UK?

The standard rate of VAT in the UK is 20% for most goods and services, with 5% and 0% rates for specific supplies; other supplies are exempt from VAT.

Since 4 January 2011, the UK's headline VAT level has stood at 20% on the majority of supplies, and that remains the position in 2026. The standard rate does not apply to everything. Supplies fall into four bands, which HMRC sets out in its VAT rates guidance on GOV.UK, and the UK VAT rates table below summarises them.

Zero-rated supply is not synonymous with tax exemption. Zero-rated goods and services are taxable supplies charged at 0%, so their sale and purchase must still be accounted for and recorded in VAT returns. Exempt supplies are not outside the VAT system; no VAT is charged on them. They are not taxable supplies, so input tax relating to them is generally not reclaimable. Businesses must keep records of exempt transactions and include exempt sales on VAT returns where required. Input tax relating to exempt supplies is generally not reclaimable, although partial exemption rules may allow some recovery.

1. Standard rate (20%)

The default rate for most goods and services, including electronics, adult clothing, restaurant meals and most professional services. Taxable supplies that are not reduced-rated or zero-rated generally fall into this band; exempt and out-of-scope supplies do not.

2. Reduced rate (5%)

Applies to specific supplies, such as domestic fuel and power, some residential conversions and renovations, and certain mobility aids supplied with installation to people aged 60 or over.

3. Zero-rated supplies (0%)

Covers most food, children's clothing and footwear, books and printed materials, and women's sanitary products, which have been zero-rated since 1 January 2021. Not all drinks are zero-rated, and these sales still appear in VAT returns.

Exempt supplies (not a VAT rate)

Includes most financial and insurance services, certain postal services, and the sale, leasing and letting of land and buildings. Commercial landlords can opt to tax a property, which makes those supplies standard-rated instead.

How and When Do You File a UK VAT Return?

Most VAT-registered businesses file quarterly, with the return and payment due one month and seven days after the end of each VAT period.

Once registered, a business reports its output tax and input tax for each VAT period, which usually runs for three months. Unless exempt, businesses must keep digital records and submit returns using software compatible with HMRC's Making Tax Digital for VAT (MTD) rules. The cycle runs in four steps:

Step 1: Keep digital records under Making Tax Digital

Unless exempt, VAT-registered businesses must keep the required records digitally, whatever their turnover. They can use compatible software or spreadsheets connected to HMRC through bridging software.

Step 2: Submit the return by the deadline

1. Note that the return is due one month and seven days after the VAT period ends.
2. Businesses exempt from MTD can file by post or through their VAT online account.
3. Most businesses file four times a year on HMRC's default quarterly periods.

Step 3: Pay HMRC by the same deadline

Payment is due with the return, and a direct debit can automate it. Late filings attract penalty points under HMRC's points-based regime, while late payment adds percentage penalties and interest under separate rules.

Step 4: Review whether a VAT scheme suits you

1. For entry to the Flat Rate Scheme, check whether your expected taxable turnover for the next year is no more than £150,000, excluding VAT.
2. Consider the Flat Rate Scheme, which uses a fixed percentage of gross sales.
3. Consider the Cash Accounting and Annual Accounting Schemes for payment timing and filing frequency; each has its own eligibility rules.
4. Review scheme eligibility again at your first VAT year end.
