Tax Codes and Tax Rates
Tax Codes are used to create varying tax codes at the parameter level. You must first set up and create your own tax codes. You can then create several tax codes and split the accumulation of tax by subsystem.
Tax Rates are defined per tax code and has an effective date that determines the current rate to use. The most recent rate defined is used as long as the effective date is less than or equal to the date requested. You can determine future GST amounts by allowing applications to pass the effective date.
