Product Category Fiscal Classification

Hi

Some category of goods/services are taxed at 10%, some at 6% etc. Transactions are also coming from external systems - some of them are sending tax exclusive and some are sending tax inclusive. To cater to this, we are thinking to define 10E as in Exclusive tax and 10I as in Inclusive tax.

Query: At the category level, we are saying that this goods are grouped as say 10%. Then how at tax rules level system will understand that this is 10E or 10I. Do we have to create separate rule for 10E and separate rule for 10I?

Appreciate any inputs on the same.
