Need Tax to be displayed in cart even if 0%

Hi, when I sell within European Union, there is the regular 19% tax which is diplayed in the checkout process . If a customer form a non EU country registers, he gets displyed the ex VAT prices, as he does not have to pay them. However the tax line is not shown in the cart, when tax is 0%. To make it clear that the displayed prices do NOT contain taxes, I would like to have the tax line displayed, showing a 0.00 Euro line.

I guess there is somewhere logic in Hikashop that supresses the tax line during checkout when tax rate is 0%. How can I correct this?

Thank ins advance as always.
