in order to meet regulatory compliance in EU, we need to include the total VAT amount we are charging for VAT in every invoice. I can get the Total and Sub total amount, but i need Total VAT amount which is (total - sub total). How can I achieve this?

I couldn't find any relevant placeholder for this.

For example:

I'm billing customer for 100 EUR

VAT is 19%

SubTotal is: 100 EUR

Total is: 119 EUR

Total VAT is: 19 EUR

How can I get the Total VAT amount into template?

Many thanks!
