I need to have the total price with tax (Quebec taxes) but it doesn't work. I can see the tax amount but it's not added to the total amount of the order.
1. I defined the tax value in "Taxes lookup" (See screenshot)
2. I have Price includes taxes set to have the tax in the total
3. I defined quebec taxes as default tax in system settings
Seems that due to your business task you need to disable the system setting. Please disable the system setting, relogin to the system, create new order, add a product there and check the result.
