Need to show required price addition

Hi, German law requires to depict behind each and every price listing to add a phrase saxing "(includes 19% MWSt)" or to show a disclaimer on all pages with prices that shown prices include the 19% VAT. Up to now I have complied in adding just the above term in my German language file for the HIKASHOP_FINAL_TOTAL and translating the PER_UNIT into (enthält 19% MWSt). With this solution it is shown right next to each price on the category listing, product page, cart and checkout.

I now realize that if someone from Switzerland (German speaking but prices do not contain VAT) gets the same message, however he should read (excludes VAT).

How could I accomplish this? I think one option would be to display on each page the footnote:" Prices contain 19% MWSt" if the client is in a country where VAT applies and the remark "Prices do not contain VAT). And how can I make sure this footnote is shown on each page?

The other option (preferred) would be to show the correct remark next to each price. How could I accomplish that?

Hi, this is exact what I was looking for. Now I want to include this into cart as well to show incl VAT or excl VAT for the HIKASHOP_FINAL_TOTAL.

However this exact solution does not work. It would show always excl VAT. Could you help me with the correct syntax to include after the line
<?php echo JText::_('HIKASHOP_FINAL_TOTAL');

thanks in advance!
