If your business makes taxable sales to customers in Alabama, you may need to register for an Alabama Sales Tax License before collecting sales tax. This 2026 guide explains who must register, what information you need, and how to complete the registration process through My Alabama Taxes (MAT). It also covers the Simplified Sellers Use Tax (SSUT) program, which simplifies compliance for most remote sellers.

Who must register for Alabama sales tax
You must register for an Alabama Sales Tax License if your business has a sales tax nexus in the state. This usually applies when a business:
- Exceeds the economic nexus threshold of $250,000 in annual sales into Alabama in the current or previous calendar year, or;
- Has a physical presence in Alabama, such as an office, employee, warehouse, or inventory stored in the state.
Alabama's economic nexus threshold is higher than the $100,000 threshold used by most states, and there is no separate transaction count threshold. You only need to register once you cross the $250,000 sales mark.
Once you exceed the threshold, you should register before making further taxable sales in Alabama. If you're unsure whether your business has nexus, see the Alabama Sales Tax Guide for a broader explanation.
The Simplified Sellers Use Tax (SSUT) program
Alabama offers a program specifically designed for remote sellers called the Simplified Sellers Use Tax (SSUT). Instead of collecting the 4% state rate plus varying city and county rates, SSUT participants collect a flat 8% rate on all Alabama sales regardless of where the buyer is located in the state.
This is a significant simplification. Under the standard sales tax program, Alabama's local rates vary widely by city and county, and some cities administer their own local taxes separately. Tracking and remitting those rates adds substantial compliance complexity. SSUT eliminates this by replacing all those rates with a single flat rate.
Most remote sellers and businesses selling digital products into Alabama choose SSUT. If this program applies to your situation, you enroll through MAT at the time of registration.
How to register for Alabama sales tax
Sellers can register online through My Alabama Taxes (MAT), the state's centralized tax portal. This is the same portal you will use to file returns and make payments after registration.
Information you need before registering
Before applying for an Alabama Sales Tax License, have this information ready:
- Your Social Security number (if registering as a sole proprietor with no employees)
- Your Employer Identification Number (EIN), if your business has one (required for corporations, partnerships, and most LLCs)
- North American Industry Classification System (NAICS) code for your primary business activity
- The date of your first sale in Alabama
- Your business address and any Alabama locations, if applicable
- Your decision on whether to enroll in the SSUT program (recommended for most remote sellers)
Registration steps
Follow these steps to register for an Alabama Sales Tax License.
1. Create your online login
Set up your My Alabama Taxes account credentials.
- Choose a username and password
- Set up your security information
- This login is used for all future filings, payments, and account management
If you already have a MAT account, you can add a sales tax account to your existing login.
2. Provide your business information
Enter your business name, address, type of entity, and any Alabama locations.
- Remote sellers without an Alabama location should indicate they are selling remotely
- At this stage, you will choose whether to register under the standard sales tax program or the SSUT program
3. Choose between standard registration and SSUT
This is a key decision for remote sellers.
- Standard program: You collect the 4% state rate plus applicable local city and county rates. Some cities require separate registration and filing.
- SSUT program: You collect a flat 8% rate on all Alabama sales and file a single return through MAT. No separate local registrations required.
Most remote sellers and digital product sellers find SSUT significantly easier to manage. The trade-off is that the flat 8% rate may be higher than the combined rate in some localities, but the simplicity typically outweighs this for businesses without a physical Alabama presence.
4. Submit your application
Review your entries and submit the application.
- There is no registration fee for an Alabama Sales Tax License
- You will receive an on-screen confirmation after submission
- A confirmation email is typically sent shortly after submission
5. Receive your Alabama Sales Tax License
Once approved, you will receive:
- Your Alabama Sales Tax License number (used for filing and payments)
- Your assigned filing frequency (monthly, quarterly, or annually, based on expected tax liability)
- Access to MAT for filing, payment, and account management
What happens after registration
After registering, you must begin collecting Alabama sales tax on taxable sales and file returns based on your assigned filing frequency. Alabama sales tax returns are due on the 20th of the month following the reporting period.
If you enrolled in SSUT, collect the flat 8% rate on all Alabama sales and file a single return through MAT. If you registered under the standard program, you collect the 4% state rate plus applicable local rates, and may need to file separately with certain cities.
