A Product category is a type of product. The user creates product categories to organize products. With this, we can easily define our products in different-different categories. This article explains how to change the tax rate for the Product through the Category tax in Products option. Suppose users want to change tax rates on all products according to category. They can change it from the GST Updates section in the 'System Maintenance' form.
For example, a bottle is your product category in which sales and purchase tax were applied 12% previously. For now, the tax rate has been changed from 12 to 18%, and you want to update it in every product under that category. You can simultaneously update tax in products with this option.
