Alabama's remote-seller economic threshold is generally measured against direct retail sales into the state.
Eligible remote sellers may use Alabama's Simplified Sellers Use Tax program after being accepted.
SSUT returns and payments are generally due by the 20th day of the month after the tax period.
Quick answer for ecommerce sellers.
If you sell products to Alabama customers, you may need to register, collect, and remit Alabama sales or sellers use tax once you have a physical presence in Alabama or meet Alabama's remote-seller rules. For many out-of-state ecommerce sellers, the first question is whether direct Alabama retail sales have crossed the state's $250,000 threshold.
Alabama also has a Simplified Sellers Use Tax program, often called SSUT. Eligible remote sellers that are accepted into the program collect, report, and remit a flat 8% sellers use tax on Alabama sales instead of trying to apply every local rate. That can simplify the return, but it does not remove the need for clean source data, marketplace separation, timely payment, and audit-ready records.
What creates Alabama sales tax nexus?
Nexus is the connection that can make a seller responsible for Alabama sales tax compliance. For ecommerce merchants, Alabama nexus usually comes from one of two buckets: physical presence or economic activity.
- Physical presence: inventory, an office, a warehouse, employees, contractors, retail activity, or other in-state operations can create a filing obligation.
- Economic nexus: out-of-state sellers may trigger Alabama obligations when they exceed the state's remote-seller threshold for Alabama retail sales.
- Marketplace activity: marketplace facilitators can have their own Alabama collection obligations. Marketplace sales collected by an SSUT participating marketplace are generally treated differently from a merchant's direct sales when reviewing threshold and filing data.
The practical takeaway: do not review only your total company revenue. Pull Alabama destination sales by channel, separate marketplace-collected orders from direct website orders, and document the measurement period you used.
How Alabama registration fits into the workflow.
Before filing Alabama returns, a seller needs the right account setup. Alabama remote sellers may apply through My Alabama Taxes, and SSUT participation requires approval before a seller collects and remits the flat 8% SSUT rate.
Registration is not just a form submission. Your filing workflow should capture the legal business name, FEIN, responsible party, account type, filing frequency, start date, login credentials, payment method, and whether the account is standard sales and use tax or SSUT. Those details determine how the monthly packet should be prepared later.
For teams using multiple data sources, this is where most future filing issues begin. If Shopify, Amazon, Walmart, Stripe, QuickBooks, and spreadsheets all describe Alabama sales differently, the return preparer needs a clear rule for which report is the source of truth.
What to collect on Alabama sales.
Alabama's standard sales tax structure includes state and local layers, while the SSUT program gives eligible remote sellers a flat 8% collection path for qualifying sales. Which path applies depends on the seller's status, location, program approval, and whether the transaction is handled by a marketplace facilitator.
For merchants, the cleanest collection review uses three separate groups:
- Direct ecommerce sales: orders from your own website or checkout where your business is the seller of record.
- Marketplace sales: orders where a marketplace facilitator may be collecting and remitting Alabama tax on your behalf.
- Wholesale or resale sales: transactions supported by valid resale documentation rather than end-consumer tax collection.
Mixing those groups together is how sellers overstate taxable sales, understate tax collected, or file a return that does not match their platform records.
How to prepare an Alabama sales tax filing packet.
A good Alabama return process starts before the due date. The goal is to turn raw sales data into a repeatable packet that someone can review, approve, file, and defend later.
- Export the period data: pull the exact month or quarter from every relevant channel and confirm the date range matches the filing period.
- Separate channel types: split direct sales, marketplace-collected sales, wholesale/resale transactions, refunded orders, and exempt transactions.
- Reconcile totals: compare gross sales, taxable sales, tax collected, refunds, and marketplace tax to the accounting file or payout reports.
- Prepare the return summary: document the numbers used for Alabama, the source report, the filing account, and the payment amount.
- File and save proof: keep the confirmation, payment receipt, source reports, and review notes together in one folder.
For SSUT participants, Alabama says SSUT is electronically reported and paid by the 20th day of each month for the preceding month's tax collected. If paying electronically, the state notes that EFT payment information must be transmitted by 4 p.m. Central time on or before the due date to be considered timely.
What happens if Alabama filings are late or wrong?
Late or inaccurate filings can create penalties, interest, account notices, and more time spent cleaning up the account. The most common risk for ecommerce sellers is not intentional noncompliance. It is a messy data handoff: marketplace sales included in the wrong bucket, a refund report missing from the packet, a payment not scheduled before the deadline, or a return filed from a report that does not match the accounting system.
A simple review checklist helps reduce that risk:
- Was the Alabama account active for the period being filed?
- Did the report exclude marketplace tax already collected by a marketplace?
- Were exempt, wholesale, and resale transactions documented?
- Does tax collected in the platform reconcile to the return amount?
- Was the confirmation saved after filing and payment?
Alabama sales tax FAQ.
Do online sellers need an Alabama sales tax permit?
They may. A permit or SSUT account may be needed if the seller has physical presence in Alabama or meets Alabama's remote-seller threshold. Sellers should confirm their exact account type before collecting tax.
What is Alabama's economic nexus threshold?
Alabama's remote-seller threshold is generally $250,000 in Alabama retail sales. Alabama guidance says the threshold calculation should include direct retail sales and exclude wholesale resale sales with proper Alabama resale documentation and sales through an SSUT participating marketplace that collects Alabama tax for the marketplace seller.
Do marketplace sales count the same as direct website sales?
No. Marketplace facilitator rules can change the filing treatment. Merchants should separate marketplace-collected orders from direct ecommerce orders before deciding what to report.
When are Alabama SSUT returns due?
Alabama says SSUT is electronically reported and paid by the 20th day of each month for the preceding month's tax collected. Due dates can shift around weekends or holidays, so verify the current period inside My Alabama Taxes.
