Guide Summary & Key Takeaways

If you do business in the UK or Europe, Value Added Tax (VAT) is a strict requirement. Missing your VAT number on an invoice can invalidate it.

In the US, Sales Tax is relatively simple. In the UK and Europe, VAT (Value Added Tax) is complex and strictly regulated. A "VAT Invoice" requires specific information beyond a standard invoice, and getting it wrong can result in penalties.

Required Fields for VAT Invoices

  • Your VAT Number: Must be clearly visible on every invoice.
  • The Tax Date: The date the service occurred (tax point), which may differ from the invoice date.
  • VAT Rate Per Item: You must list which items are at 20% (standard), 5% (reduced), or 0% VAT.
  • Total VAT Amount: The total amount of tax being charged, shown separately from the subtotal.
  • Customer's VAT Number: Required for B2B transactions within the EU (for reverse charge purposes).

When Do You Need to Register for VAT?

  • UK: When your taxable turnover exceeds £85,000 in a 12-month period
  • EU: Varies by country (e.g., €22,000 in Germany, €85,800 in France)
  • Voluntary registration: You can register before hitting the threshold to reclaim VAT on your business purchases
