Can magento ...manage different tax_class - VAT (IVA in italy) for the same product?
When a specific product is selected I would want to give the possibility to select:
Then in the checkout I need to visualize --> subtotal + tax
For a product with price 10,00 €
Is it possible?
Does a module exist?
That is not possible with Magento by default. I am sure that there is a rule for the different tax rates (by location / customer group).
I suggest applying a logic rule apply the different tax rate based on a specific condition, or try to build a custom solution based on your specific tax rules.
