Alabama Sales Tax and Invoicing Rules for 2026

TL;DR: Alabama has a 4% state sales tax with city and county taxes pushing combined rates to 5%–11%. Alabama administers state and local taxes separately through the Simplified Sellers Use Tax (SSUT) program. Economic nexus applies at $250,000 in annual sales — one of the highest thresholds in the country.

State sales tax rate

Alabama imposes a 4% state sales tax. Cities and counties add their own taxes, with combined rates varying dramatically from 5% to 11% depending on location.

Birmingham has a combined rate around 10%. Montgomery is approximately 10%. Mobile sits at about 10%.

Alabama's local tax administration is uniquely complex — cities self-administer their own sales taxes rather than having the state collect on their behalf. The Simplified Sellers Use Tax (SSUT) program was created to ease this burden for remote sellers, allowing them to collect a flat 8% rate that covers state and local obligations.

Alabama uses origin-based sourcing for in-state sellers.

Nexus rules

Physical nexus applies through offices, employees, inventory, or property in Alabama.

Economic nexus triggers at $250,000 in gross sales into Alabama in the prior calendar year — one of the highest thresholds in the country. There is no transaction count requirement.

Remote sellers meeting this threshold can simplify compliance by participating in the SSUT program administered by the Alabama Department of Revenue, which allows collecting a flat 8% rate instead of managing individual city and county tax rates.

Marketplace facilitators must collect and remit on behalf of third-party sellers.

Invoice requirements

The Alabama Department of Revenue requires sellers to maintain adequate records. Invoices should include:

• Seller's name, address, and tax account number
• Date of sale
• Buyer information
• Description of goods or services
• Sale price
• Tax rate and tax amount (separately stated)
• Total

For sellers using the SSUT program, the flat 8% rate simplifies invoicing significantly. For sellers registered directly with cities and counties, each jurisdiction's rate must be correctly applied based on the delivery address. For exempt sales, retain the appropriate exemption certificate. Records should be kept for at least three years.

Exemptions and special cases

Groceries are fully taxable in Alabama at both state and local rates — Alabama is one of the few states that taxes food for home consumption at the full rate (recent legislative efforts have discussed reducing or eliminating this).

Prescription drugs are exempt from state tax but may be taxable at the local level. Farm equipment and agricultural inputs have exemptions. Manufacturing machinery is exempt from state sales tax.

Clothing is fully taxable. SaaS and digital goods — Alabama has limited guidance, but the state generally taxes tangible personal property and has not broadly classified SaaS as taxable.

Filing frequency and deadlines

State returns are filed monthly (due the 20th of the following month) for most businesses. Smaller sellers may qualify for quarterly filing.

The SSUT program has its own filing schedule — SSUT returns are filed monthly through the Department's online portal. For sellers registered directly with self-administering cities, each city has its own filing schedule and due dates — this is the complexity the SSUT program was designed to avoid.

There is no vendor discount at the state level.

Penalties for non-compliance

Late filing incurs a 10% penalty on unpaid state tax (minimum $50). Interest accrues at 1% per month on unpaid tax.

Individual cities may impose their own penalties for late filing of local taxes. Failure to register when nexus exists results in back-assessments. Alabama's audit division focuses on both state and local compliance, and the self-administered city system can create unexpected audit exposure.

FAQ

What is the SSUT program?

The Simplified Sellers Use Tax program allows remote sellers to collect a flat 8% rate on all Alabama sales instead of managing dozens of individual city and county tax registrations and filings. You register through the Alabama Department of Revenue and file monthly.

Does Alabama really tax groceries at the full rate?

Yes. Alabama is one of a small number of states that taxes food for home consumption at the full state and local rates. There has been legislative discussion about changing this, but check for recent updates.

Why is Alabama's local tax system so complicated?

Alabama allows cities to self-administer their own sales tax — each city handles its own registration, filing, and collection independently from the state. A seller might need to register with dozens of individual cities. The SSUT program was specifically created to solve this for remote sellers.
