Scope:All WLPs need to send exemption forms to PBXio for whichever states they are conducting business in and are requesting exemption. The following links below will direct you to the forms needed. Please note that some forms are state specific and are only needed if you are conducting business in that state. Taxes will not be retroactively credited after they have been charged. All completed exemption forms need to be sent to billing@PBX.io and taxexemption@csilongwood.com upon completion. If you have any questions, please reach out to billing@PBX.IO or call the office.
