ThePolovsky Posted December 31, 2019 Share Posted December 31, 2019 Hi guys, I would like to report a problem I am having with VAT calculation on whmcs 7.8.3. I am using the "Inclusive Tax - prices are entered including tax" at the rate of 18.00%, but the WHMCS is miscalculating VAT. For example: 18% of 45 it calculates 6.86, but it is 8.10 and is supposed to be subtotaling and not totaling. How can I resolve this issue? Can someone help me? Thank you 0 Quote Link to comment Share on other sites More sharing options...
