What a UK VAT invoice must include
If you are VAT registered in the UK, HMRC expects a specific set of details on every invoice you issue. Miss one and your client may not be able to reclaim the VAT — which is usually when you find out.
- A unique, sequential invoice number
- Your business name, address and VAT registration number
- Your client’s name and address
- The invoice date, and the supply date if it differs
- A description of the goods or services supplied
- The quantity and unit price of each item, excluding VAT
- The VAT rate applied to each item, and the amount of VAT charged
- The total excluding VAT, the total VAT, and the total payable
The generator above puts all of these on the PDF when you use UK mode and enter your VAT number. If you are not VAT registered, leave the VAT number blank and set every line to 0% — you must not charge VAT, and the invoice should not mention it.
