Big TAX bug

Hello,



We have setup some TAX options. For us a cusomers pays 19% tax.



For example a product cost 75 euro. So 75 / 100 * 19 = 14,25 euro TAX but on the invoice it’s saying € 11.97. This is very bad an needs to be fixed asap.



Prices added to the site are with TAX included.



Regards,



Erwin
