General Business License
Louisiana requires most businesses to obtain a Louisiana Sales Tax Certificate of Registration from the Department of Revenue. Additionally, businesses must register their entity with the Louisiana Secretary of State. Louisiana's local government structure based on parishes (not counties) means parish-level business licensing varies significantly. New Orleans, Baton Rouge, and other cities have their own business licensing requirements. Louisiana also operates a geaux.biz.la.gov portal for business registration.
