If there are more specific tax requirements for your state, province or country, you may always set those up later. Art Storefronts strongly recommends creating a state or province wide tax method to start with. You can come back and change it later.
ART STOREFRONTS RECOMMENDATION
Art Storefronts cannot give you specific tax advice. We are not accountants nor are we versed in the tax laws of all communities. If you require specific information or assistance, you will need to contact a CPA local to you or contact your local tax agency for more information.
