This module has been developed specially for calculating taxes in Canada (GST,PST,HST,QST). Once the module is enabled, you have all destination zones set up as well as provincial rates accordingly assigned.
You can edit tax rates for each province if necessary. Also, you can set several taxes for a province based on customers memberships.
Canadian Taxes module allows you to define which address should be used to calculate tax rates – shipping or billing address, select the taxable base for all provinces or for each province individually, set GST % rate and specify merchant GST registration number. Tax amount will be displayed on checkout when a customer specifies the province.
