Hi @goofyco,
This is certainly possible using Premium Templates. This extension includes a customizer that allows you to tailor your PDF documents using product columns and total rows blocks, as well as custom blocks that you can place in different areas of the document (currently 20 different ones) and display based on given conditions (order status, payment method, billing or shipping country, etc). The customizer also allows you to sort items by product name, SKU and category. In addition, Premium Templates provides two additional templates: Business and Modern.
For your specific case, you could use the VAT block, in the total’s row:

…and Tax Rate and VAT item column blocks:

Then, your invoice should look like this:

By the way, since WordPress doesn’t allow us to provide support for paid plugins in this forum, please contact us by email: support@wpovernight.com if you have more questions about Premium Templates.
Hi Yordan,
we have Premium templates addon.
I followed your settings, but it doesnt show a line for VAT. Actually nothing semms to change.
I will send you details to the e-mail.
Thanks & best
Update: It turned out that the template selected was Simple instead of Simple Premium: The Simple template has limited compatibility with the customizer.
I’m marking this ticket as Resolved.
