DynamicZip has a feature called Tax By Item Category that allows you to control the taxation of inventory items, freight, and miscellaneous charges on a per state basis. The DZ Tax By Item Category Setup window allows you to choose a state, an Item Category and a Tax Option
For Freight Charges: - Create the Item Category FREIGHT using the DZ Item Category Maintenance window
NOTE: Please follow the same steps for Miscellaneous charges, only use MISC for the Item Category.
NOTE:The CCH ZIPsales Database includes the Zipsales Database Rules file . You may be able to use the information contained in this file to help you determine which charges are taxable in which states.
