Hi,
Yes, if you look there, you can see that the system can display payment fees with taxes or without. It depends on the "show taxed prices" setting of the HikaShop configuration.
if($pt > 0)
$price_text .= $this->currencyHelper->format($method->payment_price_with_tax,$method->payment_params->payment_currency);
if($pt == 2)
$price_text .= JText::_('PRICE_BEFORE_TAX');
if($pt == 2 || $pt == 0)
$price_text .= $this->currencyHelper->format($method->payment_price,$method->payment_params->payment_currency);
