This module replaces your existing shipping costs module.
It divides the tax on the shipping costs according to the contents of the shopping cart.
For example: you have products with 7% VAT for 100 euros in your shopping cart and products with 19% VAT for 100 euros.
You take 6 euros gross for shipping. Then these are divided into 3 euros incl. 7% and 3 euros incl. 19% VAT and your tax office is happy :)
If you would prefer the shipping tax to be based entirely on the majority of the shopping cart, then take a look at this module here.
