The Default Address module lets you define the country and state to use for tax calculations before the customer has entered their details.
If you only sell in a specific country or state, or the vast majority of your clients come from a specific country or state, this allows Commerce to show the right tax totals right away.
An alternative method to show the right tax totals dynamically is to use the Autofill GEO IP module, which will geolocate the customer’s IP address to guesstimate the country and optionally state.
- Default Country: the country to use by default.
- Default State: the state/province to use by default.
