Sales Tax in Alabama: A Complete Guide for Ecommerce Sellers

Alabama has two distinctive features: a higher-than-standard $250K economic nexus threshold, and the Simplified Sellers Use Tax (SSUT) program: a flat 8% rate that covers state and all local jurisdictions, available to qualifying remote sellers. Alabama’s underlying local rate structure is among the most complex in the country, with hundreds of city and county jurisdictions and combined rates exceeding 10% in some areas. For most remote ecommerce sellers, the SSUT program is the most practical compliance path.

Quick reference

Economic nexus

Alabama’s threshold: $250,000 in annual retail sales into Alabama. There is no transaction count threshold.

Alabama enacted its economic nexus rules effective October 1, 2018. The $250K threshold is one of the highest among US sales tax states, most states use $100K. Many sellers with nexus in 30+ other states do not trigger Alabama nexus because they fall below this higher threshold.

Physical nexus

Physical presence in Alabama creates nexus without any threshold:

• Warehouse, office, or storage facility in Alabama
• Amazon FBA inventory in Alabama fulfillment centers
• Employees, agents, or independent contractors in Alabama
• Sales representatives in Alabama

Registration

SSUT program (recommended for most remote sellers): Enroll through the Alabama Department of Revenue’s My Alabama Taxes portal (myalabamataxes.alabama.gov). Collect and remit 8% on all Alabama sales. File one quarterly return with ADOR. Significantly simpler than the full rate structure.

Standard registration: Register separately with the state and with each applicable local jurisdiction. Alabama cities and counties administer their own sales taxes independently, separate filings may be required for Huntsville, Birmingham, Jefferson County, Mobile, and others.

Tax rates

State rate: 4%

County and city additions: Alabama’s local rate structure involves hundreds of individual jurisdictions. Counties levy their own rates, and cities layer additional rates on top. Combined rates in major Alabama cities:

• Birmingham: up to 10%+ combined (city + Jefferson County + state)
• Tuscaloosa: up to 10% combined
• Huntsville: approximately 9% combined
• Mobile: approximately 10% combined
• Montgomery: approximately 10% combined

Some smaller municipalities with additional special taxes can reach 12%+ combined.

SSUT flat rate: 8% on all Alabama sales. The SSUT rate is distributed by ADOR to the appropriate local jurisdictions. For remote sellers, this eliminates the need to track and apply hundreds of local rates.

What’s taxable

Generally taxable: Electronics, clothing, furniture, sporting goods, toys, most tangible personal property.

Generally exempt:

• Prescription medications
• Most food for human consumption (groceries — Alabama exempts food from the state 4% rate, though local taxes may apply)
• Agricultural equipment and supplies
• Industrial machinery for manufacturing

Notable Alabama rules:

• Food: Alabama exempts food from the state 4% rate, but county and city taxes typically still apply to food. Under SSUT, food is taxable at the full 8% — sellers of food products should confirm SSUT treatment vs. full rate structure implications
• Clothing: Taxable in Alabama, no clothing exemption
• Digital products: Alabama taxes specified digital products and has taken an expansive position on digital content and software

Shipping taxability

Alabama taxes delivery charges when the shipped goods are taxable. Delivery charges are part of the taxable gross receipts when the goods being delivered are subject to tax.

Under the SSUT program, delivery charges are included in the taxable sale price when goods are taxable.

Marketplace facilitator rules

Alabama enacted marketplace facilitator legislation effective January 1, 2019. Qualifying marketplace facilitators collect and remit Alabama sales tax on marketplace-facilitated sales.

Under the SSUT program, remote sellers whose only Alabama sales are through marketplace facilitators may not need to separately enroll in SSUT. Sellers with Alabama physical nexus must register regardless.

State-specific notes

SSUT is the right answer for most remote sellers: Alabama’s underlying local rate structure, hundreds of independently administered jurisdictions, some requiring separate registration and filing, is one of the most complex compliance environments in the country. The SSUT program at a flat 8% is specifically designed to give remote sellers a manageable path. Any remote seller above $250K in Alabama sales should strongly consider SSUT.

$250K threshold filters out smaller sellers: Alabama’s nexus threshold is more than double the standard $100K. A seller generating $150K/year in Alabama sales does not trigger economic nexus under Alabama’s rules, even though the same sales would trigger nexus in most other states.

Security deposit requirement: Alabama historically required a security deposit of approximately 3× estimated monthly liability for new registrants under the standard registration system. The SSUT program does not require a security deposit, which is another reason remote sellers prefer it.

Local self-administration: Some Alabama municipalities (including Birmingham) administer their own sales tax separately from ADOR. Under standard registration (not SSUT), sellers may need to file separate returns with the city in addition to the state. SSUT consolidates all of this into one quarterly state return.
