There are a number of ways to display VAT on your invoices.
You can either show the VAT amount per line on the invoice or you can show just the total at the bottom of the invoice.
If you show the total at the bottom then you also have the option of just showing the total VAT amount, or a breakdown of VAT at different rates – ie, £12 @ 5% + £17.50 @ 15%.
You can set your preference in Settings > PDF Themes> Theme in question> Misc Options> Tax Layout.
