Tax Calculation

The service can calculate the following types of taxes:

US sales and sellers use tax

Canadian sales tax (GST, PST, HST, QST)

International (non-US/Canadian) and Value-Added Tax (VAT)

The calculation is based on the location of the customer’s taxing jurisdiction, your nexus locations, and the product codes that you provide. The order price and quantity are included in the calculation.

The tax calculation service is not recommended for merchants conducting business with unsupported countries. See Supported Countries and Regions.
