To create an invoice or receipt with 100% VAT, go to Invoices or Purchases > Create new Invoice or Purchase
Add a line item to the invoice;
- Quantity – 1
- VAT Rate – anything other than “n/a”
- VAT Amount – the value of the VAT
The VAT rate you select in the drop-down box is only used to automatically calculate the VAT amount for you so by following the above example you’re just overwriting the automatically calculated VAT amount.
