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.

2. City of Birmingham Tax and License Administration Division — Business License

   Every person, firm, or entity doing business within Birmingham city limits must register with the City of Birmingham Finance Department and obtain a city business license from its Tax and License Administration (Revenue) Division, under the Business License Code (Ordinance No. 97-183, as amended). Apply on the Application for Tax Certificate (ATC) form in person at City Hall, Room TL-100, 710 North 20th Street, Monday–Friday 8:00 a.m.–5:00 p.m. The business address must first be zoning-approved by the Department of Planning, Engineering and Permits, and a home-based business must first execute a Home Occupation Certificate of Agreement with that department. Supporting documents vary by entity and activity — Articles of Incorporation for corporations, a Health Department permit for food and eating establishments, a Zoning Certificate of Operation plus a county or state license for day care centers, and proof of state licensure for regulated trades such as master electricians, master plumbers, and HVAC contractors. Each business location requires its own license. Licenses expire December 31; general business renewals are due February 15 (alcoholic beverage January 15, insurance companies March 4), and the license must be posted in a conspicuous place at the business. The city's Occupational Tax is a separate employer withholding obligation, not this license.

   Set by classification under the Business License Code (Ordinance No. 97-183, as amended); most Birmingham licenses are gross-receipts-based, calculated on twelve months of actual or annualized gross receipts, so there is no flat fee band or cap — a higher-revenue business pays more. A new gross-receipts business is generally issued a license in a minimum amount at application; after the first ninety days of business it must file a sworn affidavit of gross receipts for that period, which is annualized to compute actual license liability for the current and, in some cases, the second year, with amounts already paid credited and any balance billed. There is no proration if the business is discontinued. Confirm the rate and minimum for your classification with Tax and License Administration at (205) 254-2198.·New non-controlled license applications are taken and processed in person Monday–Friday during office hours, so a complete ATC package (including zoning approval and any required state or health documentation) is handled at the counter rather than over weeks; an incomplete application delays processing and issuance. Controlled licenses — alcoholic beverage, dance establishments serving alcohol, pool tables, junk yards, and solid waste facilities — are by appointment only and require separate approval, including by the Birmingham City Council, so they take substantially longer.
