The short answer
The UK's Value Added Tax (VAT) is a 20% standard-rate consumption tax charged on most goods and services, with a 5% reduced rate and a 0% zero rate for specific categories. You must register for VAT when your taxable turnover exceeds £90,000 in any rolling 12-month period — or when you expect it to exceed £90,000 in the next 30 days alone. VAT is UK-wide and administered by HMRC, and registered businesses must file digitally under Making Tax Digital.
The three rates (plus exemptions)
Rate
Applies to
Examples
20% standard
Most goods and services
Electronics, clothing, restaurant meals, professional services
5% reduced
Specific categories set by law
Domestic fuel and power, children's car seats, energy-saving materials, some residential renovations
0% zero-rated
Taxable but at 0% — you still reclaim input VAT
Most food, children's clothes and shoes, books and newspapers, public transport
Exempt
No VAT charged, and you cannot reclaim related input VAT
Insurance, finance and credit, health services, education, charity fundraising events
Zero-rated is better than exempt: a zero-rated seller charges 0% but reclaims VAT on purchases, while an exempt seller absorbs it as a cost. Reduced-rate items are narrower than many newcomers assume — most "essentials" lobbying fails because the legal list is fixed.
The £90,000 registration threshold
You must register within 30 days of the end of the month in which your rolling 12-month taxable turnover passed £90,000, and you must start charging VAT from the first day of the second month after that. The forward-looking test also triggers registration: if on any day you expect turnover to exceed £90,000 in the next 30 days alone (a single big contract, for example), you must register immediately. The deregistration threshold is £88,000. "Taxable turnover" means everything that would be VAT-able at any rate — including zero-rated sales — but excludes exempt sales and income outside the scope of VAT.
Penalties for late registration are based on how late you are and can reach a percentage of the VAT you should have charged, so monitor turnover monthly once you approach £70,000–£80,000.
Voluntary registration: worth it?
You can register below £90,000. It makes sense when most of your customers are VAT-registered businesses (they reclaim the VAT, so your prices stay competitive) and you have significant VAT-able costs to reclaim — equipment, stock, subcontractors. It usually does not make sense when you sell mainly to consumers: registration adds 20% to your prices with no benefit to the buyer, plus quarterly admin. You can reclaim VAT on goods bought up to 4 years before registration (if still on hand) and services up to 6 months before.
Charging and reclaiming: the mechanics
Registered businesses charge output VAT on sales and reclaim input VAT on business purchases, paying HMRC the difference each quarter. Keep VAT invoices for every claim — a bank statement alone is not enough. EU-style invoice requirements apply: your invoices must show your VAT number, the rate applied, and the VAT amount. File and pay quarterly (or monthly/annually under special schemes) through Making Tax Digital-compatible software — spreadsheets alone no longer satisfy the rules.
Schemes that simplify life for small businesses
Flat Rate Scheme (turnover up to £150,000 excluding VAT): pay a fixed percentage of turnover that varies by trade (for example, 14.5% for many business services, with a 1% discount in your first year of registration) instead of tracking input VAT. Simple, but usually costs more than standard accounting once input VAT is significant.
Cash accounting (turnover up to £1.35 million): pay VAT when customers pay you, not when you invoice — a lifeline for cash flow.
Annual accounting (turnover up to £1.35 million): one return a year with monthly or quarterly interim payments.
Common newcomer mistakes
Treating the threshold as per tax year — it is a rolling 12 months, checked every month-end.
Forgetting the 30-day forward test after landing one large contract.
Charging VAT before the registration certificate arrives (you can only charge from your effective registration date).
Reclaiming VAT without valid invoices, or on exempt activities.
Assuming digital services sold to EU consumers follow UK rules — the place-of-supply rules differ; check before you invoice.
Frequently asked questions
I sell only zero-rated goods. Do I still register at £90,000?
Yes — zero-rated sales count toward taxable turnover. Many food businesses register for exactly this reason: they charge 0% but reclaim input VAT, so registration is pure upside.
Can I deregister if turnover falls?
Yes, once taxable turnover drops to £88,000 or below (or you expect it to stay below £90,000 for the next 12 months). You must account for VAT on stock and assets still held, via a final return.
Do I charge VAT to customers outside the UK?
Exports of goods are generally zero-rated; services depend on place-of-supply rules (business-to-business services are usually supplied where the customer belongs). Get the rules for your specific trade before invoicing internationally.
What happens if I register late?
HMRC can backdate your registration and assess the VAT you should have charged, plus penalties scaled to how late you were and whether the failure was deliberate. Voluntary disclosure before HMRC finds you reduces the penalty.
