Frequently Asked Questions (FAQ)

QWhat are the standard statutory VAT rates in the UK?

In the UK, under the Value Added Tax Act 1994, HMRC applies three main VAT rates: Standard rate (20%) on most goods and services; Reduced rate (5%) on specific items such as domestic energy and children's car seats; and Zero rate (0%) on most staple food items, books, children's clothing, and public transport.

QWhat is the mandatory VAT registration threshold?

You must register for VAT with HM Revenue and Customs (HMRC) if your VAT-taxable turnover exceeds £90,000 within any rolling 12-month period, or if you expect turnover to exceed £90,000 in the next 30 days alone. The deregistration threshold is £88,000.

QHow do you quickly extract 20% VAT from a gross total on an invoice or receipt?

To extract 20% VAT, divide the gross amount by 1.20 to calculate the net base price. The difference between gross and net is the VAT amount. To find only the 20% VAT amount directly, divide the gross total by 6 (or multiply by 1/6 ≈ 0.16667).

QWhat is the difference between Output VAT and Input VAT?

Output VAT is the tax you charge and collect from customers on sales. Input VAT is the tax you pay to suppliers on legitimate business purchases. When filing your digital VAT Return (Making Tax Digital), you pay HMRC the difference (Output VAT minus allowable Input VAT) or claim a refund if input exceeds output.

QCan sole traders and small businesses register voluntarily before reaching the threshold?

Yes. Businesses with turnover below the £90,000 threshold can register voluntarily for VAT. This enables reclaiming input tax paid on startup equipment, inventory, and supplier overheads, and provides corporate credibility when working B2B.

QWhat is the difference between Zero-Rated and VAT-Exempt supplies?

Zero-rated goods and services carry a 0% tax rate, so you charge no VAT to the customer but can still reclaim input VAT incurred on business expenses. VAT-exempt goods and services sit outside the VAT system, meaning no VAT is charged to customers and you cannot reclaim input VAT associated with providing those exempt supplies.
