Developer: Hengsin (talk)
Feature Ticket: IDEMPIERE-5057
Description:
Implement support for https://techconcepthub.com/deductible-tax-and-non-deductible-tax/
Changes:
- Add Tax Posting Indicator field to Tax Rate window (for non-summary, line level purchase tax).
- Separate tax posting: For deductible input tax. This is the existing tax posting where tax is posted to a separate GL account from product asset account (i.e tax not added to product cost).
- Distribute tax with relevant expense: For non deductible input tax. Tax is posted to the product asset account and added to product cost.

Posting Indicator Field
- Modify tax and cost posting for Doc_Invoice, Doc_InOut, Doc_MatchInv and Doc_MatchPO.
Example:
