I have my Drupal Commerce store set up to apply my state sales tax on appropriate purchases. I also have an authorized user who has a state-approved sales tax exemption. I'm trying to configure my tax type such that no sales tax will be applied on their orders, but I'm not having much luck.
I've installed the Commerce Product Tax Conditions module, which appears to support a customer role condition. The module documentation doesn't identify that condition as "apply sales tax for this role" or "exempt this role from sales tax", though, and I haven't been able to apply an exemption.
How can I make this work?
