UK VAT invoice generator

If you are VAT-registered in the UK, a “tax invoice” must show specific details — or your client cannot reclaim the VAT and HMRC can question the invoice. The preset below pre-fills GBP, 20% VAT and a VAT number line; check the full list before sending.

What a valid UK VAT invoice must contain

For supplies under £250 a simplified invoice can suffice; for anything above, a full VAT invoice is required. The checklist (per GOV.UK guidance — verify current rules at gov.uk before filing):

A unique, sequential invoice number
Your business name and address
Your VAT registration number
The issue date and the tax point date
The customer’s name and address
Description of goods or services
The per-item rate and total amount, excluding VAT
The VAT rate applied and the VAT amount charged

Disclaimer: general information, not tax advice. Rules differ for the VAT margin scheme, reverse charge and cross-border B2B supplies — confirm with your accountant.
