Hi Jyo2, thanks for joining us on the Community :)
Our UK product is designed in line with HMRCs VAT invoice requirements; it is not currently possible to show the VAT amount per line item, only the VAT code and item amount. You can, however, include a tax summary on the invoice footer which will display the total VAT amount and net amount per tax code. To enable this, select the Cog > Custom form styles > Edit > Content > Select the footer > Tick VAT summary.
