Multiple Tax Levels in B2C Commerce

In many jurisdictions, more than one tax applies to a product or shipping charge, such as federal, state, and district taxes. B2C Commerce can track each tax individually while retaining the item's aggregated tax amount.

Your tax-provider integration can use a basket calculation hook to retrieve the taxes that apply to each line item. The integration then uses the LineItem.setTaxes() and LineItem.getTaxes() Script API methods to store the taxes on the applicable basket line items.

A line item can have up to 10 tax items. Each tax item has these properties.

B2C Commerce sums the individual tax values and stores the result in the line item's aggregated tax field. Basket, shipment, and order tax totals continue to use the aggregated value.

When B2C Commerce sends an order to Salesforce Order Management, the integration transfers the individual tax items from each B2C Commerce line item to the corresponding line item in Salesforce Order Management. You don't need custom tax fields or mapping codes to transfer this information.

Note Use either individual tax items or the existing aggregated-tax approach for a line item. You can't use both approaches for the same line item. Setting taxes with an existing single-tax Script API method removes the individual tax items previously set on that line item.

Multiple Tax Levels

A basket contains a product priced at $100. The product is subject to a 10% federal tax and a 5% state tax. Its line item contains a $10 federal tax item and a $5 state tax item. B2C Commerce stores $15 as the line item's aggregated tax value.
