To verify an Alabama sales tax exemption certificate, take the exemption number and legal entity name from the buyer’s Form STE-1, open the My Alabama Taxes portal at myalabamataxes.alabama.gov, choose “Verify Exemption Certificate” under the “I want to…” menu, and read back the status. No login is required, and the check takes under a minute. Skipping it is expensive: if the certificate turns out to be invalid, the Alabama Department of Revenue can bill you for the uncollected tax, a 10% penalty, and interest.
What to Have in Hand First
You need a copy of the buyer’s Form STE-1. It is the only exemption certificate Alabama recognizes for relieving seller liability in most transactions. Alabama Administrative Code rule 810-6-5-.02 requires the holder to complete specific fields on every copy given to a vendor, including your name and address as the vendor, a description of what’s being purchased, and the holder’s signature and title.
Two fields on that form drive the online check:
- The exemption number the Department of Revenue assigned when it approved the application.
- The exact legal name of the entity as printed on the certificate. The verification system cross-references the name against its records.
If either field is missing or hard to read, ask the buyer for a clean copy before you run the check. Trying to verify an incomplete certificate wastes time and leaves you exposed if the state later questions the sale.
Running the Check on My Alabama Taxes
Go to myalabamataxes.alabama.gov. You do not need an account. On the main page, find the “I want to…” prompt and select “Verify Exemption Certificate.” That opens a dedicated search page.
Enter the exemption number exactly as it appears on the STE-1, then enter the entity’s legal name. Check both fields for typos before submitting. The system queries the Department’s database in real time and returns the certificate’s current status right away.
Reading the Result
The tool returns one of a few outcomes, and each one tells you something different about whether to proceed tax-free.
- Active. The exemption is current and the entity is authorized to buy tax-free. You can complete the sale without collecting sales tax, provided the items fall within the scope of the exemption.
- Inactive or cancelled. The exemption has lapsed or been revoked. You collect sales tax on the transaction no matter what paper certificate the buyer produces. An expired certificate has no legal force.
- No match found. The exemption number is not in the state database. Either you typed it wrong or the certificate is fraudulent or was never issued. Re-check your entry, and if the result holds, do not honor the certificate.
The results page also shows the exemption type and the expiration date. Read both. Every STE-1 is valid for one year from issuance, and the holder must renew before the end of the expiration month. A certificate that shows active today but expires next week will not protect you on a sale completed after that date. If the buyer says they’ve “just applied for renewal,” that isn’t enough; until the Department reactivates the exemption, you collect tax. Government entities are the one exception to the annual renewal cycle, because their exemptions are defined by statute rather than by the certificate cycle.
Why Verification Is Your Protection
This is the whole reason to run the check. Alabama Administrative Code rule 810-6-5-.02 provides that a seller who relies on a Form STE-1 and reasonably believes the buyer’s exemption claim is legitimate will not be held liable for sales or use tax the Department later determines was owed. Instead, the Department pursues the party that made the illegal tax-free purchase and anyone who benefited from misusing the certificate.
The regulation is specific: Form STE-1 is the only exemption certificate that provides this liability shield for sellers acting in good faith and exercising reasonable care. Accepting a homemade letter, an out-of-state certificate, or a verbal assurance of exempt status gives you no protection if the sale turns out to be taxable. Without a properly executed STE-1 on file, the burden of proving a sale was exempt sits entirely on you as the seller, and the Department can treat the transaction as a retail sale and hold you liable for the full tax.
Running the online verification and saving the result is the simplest way to establish the reasonable belief the regulation requires.
What Happens If You Don’t
A seller who fails to collect tax on a sale that should have been taxed faces a stack of consequences. It starts with the full amount of uncollected tax. Alabama then imposes a 10% penalty on any sales tax not paid by the due date. If the balance still isn’t paid within 30 days of the Department’s first notice and demand, an additional 10% penalty applies to what remains. Interest runs on top of that from the original due date.
For a business that routinely accepts unverified certificates, these amounts compound across every transaction. During an audit the Department reviews individual sales and can assess back taxes on every one where you can’t produce a valid STE-1 and verification record. If you cannot show good faith reliance, the Department’s first stop is your business, not the buyer’s.
Records to Keep and for How Long
Alabama Code section 40-2A-7 requires every taxpayer to keep accurate and complete records sufficient for the Department to determine the correct tax, available for inspection at any reasonable time. For exemption certificates, that means keeping a copy of the buyer’s Form STE-1 and the verification confirmation for every tax-free transaction.
Print or screenshot the confirmation page as soon as you run the check. Save it with the buyer’s certificate and index it by transaction date.
The statute doesn’t set a flat retention period, but the assessment window does. The Department generally has three years from the return’s due date or filing date to enter a preliminary assessment. That extends to six years if a taxpayer omits more than 25% of the taxable base, and there is no time limit at all if no return was filed or the return was fraudulent. Keeping exemption records for at least six years covers the extended window. Many Alabama businesses keep them indefinitely in digital form since storage costs almost nothing. If you store records electronically, they must be protected against unauthorized alteration, legible, cross-referenced to your books, and producible on request.
