A higher threshold, but a fragmented local system
Alabama requires your active attention. You only need to collect tax if your sales top $250,000 — higher than most states. However, the state allows local governments to manage their own taxes, creating a fragmented system that requires separate filings for different cities.
Alabama sales tax rate table
| Field | Value |
|---|---|
| State base rate | 4% |
| Average combined rate | 9.22% |
| Local add-on range | 0% to 5.22% |
| Maximum combined rate | 9.22%+ |
| Rates vary by county/city | Yes |
| Sourcing | Based on buyer location |
Some major cities and counties (Birmingham, Montgomery, Mobile) administer their own local sales taxes separately from the state.
$250,000 — one of the highest thresholds in the country
Alabama requires remote sellers to collect once they exceed $250,000 in gross sales during the previous calendar year. No transaction count threshold.
- Marketplace sales count toward the $250,000, even though the marketplace handles the tax.
- Once you cross $250,000 in a calendar year, register by January 1 of the following year.
SaaS and digital goods are broadly taxable
Alabama treats all buyers the same — if you deliver software remotely, you must collect tax, at the full combined state and local rate.
| Product / service | Tax treatment |
|---|---|
| SaaS (B2B and B2C) | Taxable at combined rate |
| Downloaded software (permanent license) | Taxable |
| Streaming / subscription software | Taxable |
| Digital goods (e-books, music, video) | Taxable |
| Cloud storage / hosting | Taxable |
| Custom software development (services) | Often exempt |
Alabama's broad approach stems from a 2015 state Supreme Court ruling extending sales tax to remotely accessed software.
Product taxability in Alabama
| Product category | Tax treatment |
|---|---|
| Groceries & unprepared food | Reduced state rate 2% + local rates |
| Prepared food & restaurant meals | Taxable at full rate |
| Clothing & apparel | Taxable at full rate |
| Prescription drugs | Exempt |
| Baby/maternity products (2025) | Exempt (diapers, formula, wipes, breast pumps) |
| Manufacturing machinery & equipment | Exempt |
Groceries taxed: Alabama is one of only 13 states that taxes groceries — combined grocery tax can exceed 7% in some areas even at the reduced 2% state rate.
Annual Back-to-School sales tax holiday each July
Runs the third weekend of July. Exempt: clothing ≤$100/item, school supplies ≤$50/item, books ≤$30/item, computers/tablets ≤$750/item.
Most localities participate, but self-administered cities like Birmingham and Montgomery may opt out — verify local rules.
Filing and registration
Register through My Alabama Taxes (MAT). Free, 1-2 business days. Consider the SSUT program (flat 8%, separate registration) instead of tracking local rates.

| Monthly | Average liability over $2,400/month |
| Quarterly | $200–$2,400/month |
| Annual | Under $200/month |
Returns due the 20th of the month following the reporting period.
- Late filing/payment: 10% each
- Interest: 4% annually
Vendor discount: 5%, capped at $400/month (monthly) or $100/month (quarterly/annual).

Alabama IS home-rule — a real compliance burden
Major self-administered jurisdictions (Birmingham, Montgomery, Mobile) require separate registration, returns, and payments filed directly with the municipality. Alabama is not an SST member. The SSUT program (flat 8%) is Alabama's own solution for remote sellers, but its structure is under legislative review after a 2025 legal challenge.
Voluntary Disclosure Agreement (VDA)
Alabama offers a formal VDA program directly or through the MTC. Lookback typically 3 years (vs. 4-year standard). Penalties waived; interest owed. Process takes 60-90 days.
Audit risk in Alabama
ALDOR actively pursues remote sellers; self-administered cities add extra scrutiny. Common triggers: grocery vs. non-grocery misclassification, remote sellers not enrolled in SSUT but collecting below 8%, SaaS treated as non-taxable. Statute of limitations: 3 years; unlimited for fraud or non-filers.
Recent changes & quirky rules
State rate dropped from 4% to 3% to 2%, but local rates still apply on top.
Cities sued over SSUT's constitutionality in 2025; the program's future structure remains uncertain.
Exemptions & resale certificates
Alabama accepts Form ST:EX-A1. Alabama does not accept the SST Uniform Exemption Certificate. Blanket, don't expire. Common exemptions: resale, manufacturing machinery, agriculture, government, prescription drugs.
Your path forward in Alabama
- Approaching $250,000? Plan for a January 1 registration.
- Already registered? Verify your systems reflect the 2% grocery rate and new baby product exemptions.
- Remote seller weighing options? The flat 8% SSUT rate simplifies your monthly workload versus tracking 300+ local rates.
