If you have a number of line items on an invoice, the different items may be charged at different tax rates, e.g. in the UK some items are zero-rated whereas others might be subject to the standard VAT rate of 20%.
By default on an invoice template, SliQ shows a single subtotal and a single tax total. However, you can add a tax summary table (or VAT summary table) to an invoice by editing the invoice template. The summary will show a table of subtotals for the items charged at different tax rates.
