I’m looking for the option how to show after tax price on product page, when all product price are added in database without taxes. Since Japan has different calculation on product category, we need to calculate depending on product.
ex. Food category: 8% tax Coffee bean 800 yen in database will show 864 yen in actual product page.
Other category: 10% tax Shoes 2000 yen in database will show 2200 yen in actual product page.
