Sales tax calculation and posting configurations

There is an effect on the price based on the sales tax rule. Whether the price includes or excludes the sales tax can be defined as follows:

Please note that the price including the sales tax rule is configured from the following paths:
  • Navigate to General ledger | Ledger setup | General ledger parametersand then go to the Sales tax tab. Check the Amounts include sales tax checkbox.
  • The vendor master data form can be accessed by navigating to the Accounts payable | Vendors | All vendors | Invoice and delivery fast tab. Check the Price included sales tax checkbox.
  • The customer master data form can be accessed by navigating to the Accounts receivable | Customers | All customers | Invoice and deliver fast tab. Check the Price included sales tax checkbox.
  • On transaction journals for example General ledger | Journal entries | General journal, then move under the Setup tab and check the Price included sales tax checkbox.
