UK VAT Rates Explained

The UK has three VAT rates, each applying to different categories of goods and services. Choosing the right rate is essential because applying the wrong one is one of the most common HMRC compliance failures for freelancers and small businesses.

RateTypeApplies To
20%StandardMost goods and services: consulting, software, design, restaurant meals, clothing for adults, electronics, alcohol
5%ReducedDomestic fuel and power, children's car seats, mobility aids for elderly, smoking cessation products
0%Zero-ratedMost food, books and newspapers, children's clothes, prescription medicines, public transport, exports

Some goods and services are VAT-exempt (different from zero-rated): financial services, insurance, education, healthcare. Exempt items don't appear on a VAT invoice at all.

Do You Need to Register for VAT?

VAT registration is mandatory when your taxable turnover exceeds GBP 90,000 in any rolling 12-month period (the 2025/26 threshold). Below this, you can register voluntarily, which lets you reclaim VAT on business expenses but means charging VAT to clients.

Most UK freelancers and sole traders earning under GBP 90,000 don't need to register. If you're VAT-registered, you must:

Step-by-Step: How to Create a UK VAT Invoice

Step 1 - Your business identification

At the top of the invoice, include:

Step 2 - Customer details

Step 3 - Invoice metadata

Step 4 - Itemize and calculate VAT

List each service or product with quantity, unit price, and net amount. Then calculate VAT:

VAT amount = Net amount x (VAT rate / 100)
Example: GBP 1,000 x (20 / 100) = GBP 200 VAT

Show net, VAT, and gross totals separately. This three-line breakdown is legally required for VAT-registered businesses.

Real Examples

Example 1 - Standard 20% VAT on a Consulting Invoice

  1. Net amount: 10 hours x GBP 75 = GBP 750.00
  2. VAT 20% = GBP 750 x 0.20 = GBP 150.00
  3. Gross total = GBP 750 + GBP 150 = GBP 900.00

Example 2 - 5% Reduced VAT on Domestic Energy

  1. Net amount: GBP 500.00
  2. VAT 5% = GBP 500 x 0.05 = GBP 25.00
  3. Gross total = GBP 500 + GBP 25 = GBP 525.00

Example 3 - Zero-rated Book Export

  1. Net amount: GBP 2,000.00
  2. VAT 0% (zero-rated, books) = GBP 0.00
  3. Gross total = GBP 2,000.00
  4. Show on invoice: "Zero-rated supply"

UK VAT Invoice Compliance Checklist

Every UK VAT invoice MUST contain (HMRC rules):

  • Unique sequential invoice number
  • Invoice date (date of issue)
  • Tax point date (if different from invoice date)
  • Your name and address
  • Your VAT registration number
  • Customer name and address
  • Description of goods or services
  • Quantity and unit price
  • Net amount per line
  • VAT rate applied (20%, 5%, or 0%)
  • Total VAT amount
  • Gross total (including VAT)

Reverse Charge VAT for International Clients

When selling B2B services to clients in the EU or rest of the world, you usually don't charge UK VAT. Instead, the customer accounts for VAT under the reverse charge mechanism. The invoice should include:

For B2C sales to consumers in other countries, different rules apply - typically you charge UK VAT unless you've registered for the One-Stop Shop scheme.

How to Calculate VAT in Reverse (Gross Total Given)

If a price already includes 20% VAT and you need the net amount:

Net = Gross / 1.20
VAT = Gross - Net
Example: GBP 1,200 / 1.20 = GBP 1,000 net, GBP 200 VAT

For 5% reduced rate, divide by 1.05.
