There are two options for calculating taxes. You can either calculate the tax as a percentage of the order amount or specify the tax percentage for each product and calculate the taxes accordingly. The latter option is useful when the tax percentage varies by product or category. 1️⃣ Calculate tax as a fixed percentage of order amount. If the tax rate is the same for all the products / categories that you offer, then you can simply calculate the taxes by multiplying the order amount with the tax percentage.
