*This issue relates to i21 Help Desk ticket:* [ HDTN-268194 - Adjust tax calculation|https://helpdesk.irely.com/iRelyi21live/#/HD/Ticket/?ticket=HDTN-268194]
*Objective :*
Create a tax code that charges tax on tax only.
*To do:*
# Create a new Calculation Method, "Percentage of Tax Only".
# If the Tax Code (TC1) having this new Method is not linked to another Tax Code (TC2) through "Taxable by Other Taxes", then there is no calculation, because this new Method should only work during the Taxable by Other Taxes scenario.
# Amount of TC1 = Amount of TC2 * Percentage Rate (data entry in the Rate column)
# Example
## On TC2 screen, Taxable by Other Taxes has "TC1"
## TC1 setup:
### Calculation Method: Percentage of Tax Only
### Rate: 0.1
## In a transaction, amount of TC2 (Tax only) is $50.00, then Amt of TC1 = $50.00 * 0.1 = $5.00
## Show your test results in a tran with TC1's rate being both positive and negative.
# Check if there is a javascript function for tax calculation in IC module. If yes, do the necessary modification accordingly. Please check the changes in AR-14146 for reference.
