Hi,
I am really sorry but there is no rounding bug in the VAT system.
Nicolas explained you how the VAT works in the previous thread, I don't think that it is necessary to create a new thread in order to say the same thing.
Please check that HikaShop is up to date in your website.
If after the update you really think that there is a bug, please give a link to you HikaShop website. At this moment we could test it and see your problem.
I could understand that you might be frustrated and you want to have something working but we have a lot of users which use the VAT system and there is no rounding bug.
We use HikaShop for selling HikaShop, we use VAT and we don't have any problem (and we are professionals).
It is possible to override a lot of views in HikaShop and there is a lot of configuration options. We think that you might have a view/configuration problem somewhere.
After that, if you want the VAT to be applied at the end, deactivate the "show detailed taxes" option in the configuration and install and publish the plugin :
