  1. Alabama Department of Revenue - Sales Tax License

    Required for businesses making retail sales of tangible personal property in Alabama. Alabama sales tax is a privilege tax on retail sales; most services are not taxable, so service-only businesses may not need to register. Local city and county sales taxes are also due on top of the state rate and vary by jurisdiction - use ADOR's local tax rate lookup for your address. Register with the Alabama Department of Revenue via My Alabama Taxes (MAT); state and local returns are filed together through ONE SPOT.
