Invoicing in the UK

Whether you are a freelancer, contractor, or small business, a clear invoice helps you get paid on time. If you are VAT-registered, your invoice must also be a proper VAT invoice; if you are not registered, you simply leave VAT off.

What a UK invoice should include

  • A unique, sequential invoice number and the invoice date
  • Your name or business name, address, and contact details
  • Your VAT number, if you are VAT-registered
  • The customer's name and address
  • A description of the goods or services, with quantities and rates
  • The net amount, the VAT rate and amount, and the gross total
  • Your payment terms and how to pay you

UK VAT rates

The standard rate is 20%. A 5% reduced rate applies to some supplies, and others are zero-rated (0%) or exempt. Set the right rate per line item. To check the arithmetic on a price, use the VAT calculator.

Getting paid

Set clear payment terms and a firm due date - the due date calculator turns Net 7/14/30 into a calendar date. If an invoice runs late, the payment reminder generator drafts a polite nudge.

Frequently asked questions

Do I have to charge VAT as a UK freelancer or small business? +

Only if you are VAT-registered. Registration is mandatory once your taxable turnover passes the VAT threshold, and optional below it. If you are not registered you should not add VAT to your invoices. If you are registered, show your VAT number and the VAT charged. This tool supports both - set the rate to 0 or 20% as needed.

What must a UK VAT invoice show? +

A VAT invoice should show a unique invoice number, your business name, address and VAT number, the customer's name and address, the supply date (tax point), a description of the goods or services, the net amount, the VAT rate and amount, and the gross total. The standard UK VAT rate is 20%, with 5% and 0% reduced rates.
