Tax Items

Taxes differ by country and can differ within the country by region, state, or province. Each jurisdiction has a unique tax code and rate. If your store serves many jurisdictions, integrate a third-party tax generator to manage taxes. If your store serves a few jurisdictions, you can use the API to define the tax codes and rates in Composable Commerce.

Taxes are calculated after all promotional discounts have been applied. When calculating taxes on a cart or order, you can choose from the following methods for calculating taxes:

  • Simple calculation method: Taxes are calculated at the unit level and are rounded to the nearest penny for the unit.
  • Line calculation method: Default. Taxes are calculated at the line level and are rounded to the nearest penny for the line. For more information about calculation methods, see Calculate cart and order totals.

Tax items can be added and removed using client credentials tokens. Only administrators with client-credentials are able to manage tax items.
