I want to display the discount amount including tax on cart overview page (totals summary).
- Magento 2.1.8
- Catalog prices: Excluding tax
- Apply Customer Tax: After discount
- Apply Discount On Prices: Excluding tax
I cannot set
Apply Discount On Prices to
Including Tax, because Magento then calculates wrong totals. So in short I need to calculate discount amounts excluding tax but displaying including tax.
