What extra fields does a UK VAT invoice need?

A UK VAT invoice normally needs your VAT registration number, tax point, VAT rate, net amount, VAT amount, total amount, seller details, customer details, invoice number, and invoice date.

Can I issue a VAT invoice if I am not VAT-registered?

No. You should not charge VAT or issue a VAT invoice unless you are VAT-registered. Use a standard invoice instead.

What should a reverse charge VAT invoice say?

A construction reverse charge invoice should clearly state that the customer must account for VAT to HMRC. A common wording is: Reverse charge: customer to account for VAT to HMRC.

VAT fields

What a UK VAT invoice should include

VAT invoices need the normal invoice fields plus VAT-specific details that let your customer reclaim VAT where they are allowed to.

Core invoice fields

Unique invoice number.
Invoice date and tax point, if different.
Your business name, address, and contact details.
Customer name and billing address.
Description of goods or services supplied.

VAT-specific fields

Your VAT registration number.
VAT rate applied to each line, such as 20%, 5%, or 0%.
Net amount before VAT.
VAT amount charged.
Total amount including VAT.

For mixed VAT rates

If an invoice has items at different VAT rates, show each rate clearly. Do not hide everything in one total if some items are standard-rated, reduced-rated, zero-rated, or outside the scope.

For reverse charge VAT

For eligible construction services, do not add VAT to the amount due. State that the customer must account for VAT to HMRC, and show the VAT rate for reference.

FAQ

VAT invoice questions

Do I need a VAT invoice for domestic customers?

If you are VAT-registered, you still need proper VAT records. Domestic customers may not need a VAT invoice to reclaim VAT, but the invoice should still show the right VAT treatment.

What is a simplified VAT invoice?

A simplified VAT invoice is used for lower-value retail-style sales and contains fewer fields. For trades and contractor work, a full VAT invoice is usually clearer.

Do I add VAT on reverse charge construction invoices?

No. Where domestic reverse charge applies, you show the VAT rate and reverse charge wording, but the customer accounts for VAT to HMRC and the VAT is not added to the amount payable.
