I don't run 4.4.1 so I can't test it on my setup but I did try it out on the X-Cart demo site and taxes are properly multiplied by the number of items and show properly in the extended product price mini-cart and cart pages (e.g. quantity of 3 shows 3 times the tax added into the total product price). Note that you must have "Presume that a not logged in customer is from the default country" checked in your general settings for the tax to show before someone logs in.
