Calculated Tax Rates

Calculated Rate Taxes in Umbraco Commerce.

This option allows you to dynamically calculate the tax obligations of an order by using third-party calculation platforms. This complex option is useful for countries with different tax rates for different product types or regions within the country (the norm in the US).

When using calculated rate taxes, taxes are calculated as a single price adjustment against the order total price and will not offer any breakdown.

Calculated tax rates are configured using Tax Calculation Methods. A tax calculation method provides a connection to a third-party calculation service via a Sales Tax Provider. The sales tax provider passes the order details to the calculation service and returns the tax amount to be applied to the order.

Before you can configure a tax calculation method, you will need to install at least one sales tax provider.

Providing Tax Codes

When calculating taxes, you may need to provide product tax codes to the calculation service. Tax codes are used to identify the type of product being sold and used by the calculation service to determine the correct tax rate. To assign a tax code to a product, you can use a Tax Class with a code defined for the given country.
