Value Added Tax (GOV.UK) (VAT) is a consumption tax charged on most goods and services sold in the UK. It is collected by VAT-registered businesses on behalf of HMRC. When you buy something, the price usually includes VAT already. This Calculator Site tool helps you see exactly how much VAT you are paying or charging.
In business-to-business transactions, prices are often quoted excluding VAT. This is because VAT-registered businesses can typically reclaim the VAT they pay on purchases (known as input tax) against the VAT they collect on sales (output tax). You can explore how this affects overall earnings with our Take-Home Pay Calculator.
Important: VAT Registration Threshold
UK businesses must register for VAT if their taxable turnover exceeds £90,000 in a rolling 12-month period. Once registered, they must charge VAT on sales and file regular returns. Failing to register on time can lead to penalties. Some businesses below the threshold register voluntarily.
The UK has a tiered VAT system. While the standard rate is widely known, reduced and zero rates apply to specific essential goods and services, making the system more complex. Some items, like financial services, are exempt entirely. Check our Stamp Duty Calculator for another key UK property tax.
