What is VAT Invoice?
A sales invoice issued by a VAT-registered business that includes specific details required by HMRC, such as the VAT registration number and the VAT charged, so the customer can reclaim input VAT.
Full Definition
A VAT invoice is an invoice issued by a VAT-registered business that meets HMRC's specific content requirements, distinguishing it from an ordinary commercial invoice. A full VAT invoice must show a unique invoice number, the date of issue and the tax point (the date the supply is treated as taking place), the seller's name, address and VAT registration number, the customer's name and address, a description of the goods or services supplied, the quantity and unit price, the rate of VAT applied to each item (standard, reduced or zero), the total amount excluding VAT, the total VAT charged, and the total including VAT. Simplified VAT invoices, with fewer mandatory details, are permitted for retail supplies under GBP 250 including VAT, while modified invoices with additional detail are used for supplies over GBP 250 to VAT-registered customers who need to reclaim the VAT. A proper VAT invoice matters because it is normally the primary evidence a VAT-registered customer needs to reclaim the input VAT they were charged on a purchase; without one, HMRC can disallow the reclaim even where the underlying purchase and VAT payment genuinely took place, which is why keeping and issuing correctly formatted VAT invoices is a routine but important part of VAT compliance.
