Forming an LLC in Alabama costs $200 to file the Certificate of Formation with the Alabama Secretary of State, and online approval typically lands in 1–3 business days. The state has no separate LLC franchise tax, but every Alabama LLC must file a Business Privilege Tax (BPT) return every April 15 with a $50 minimum — that's the single most-missed obligation for new owners. Combined sales tax averages 9.25% (one of the highest in the U.S.), so retail and e-commerce sellers should plan their tax stack carefully. Alabama is a strong fit for solo founders in manufacturing, aerospace (Huntsville), agriculture, and small construction, and out-of-state owners can form here as long as they appoint an Alabama-resident registered agent.

How to form a Alabama LLC in 7 steps
- 1Search the Alabama LLC name database
Use the Alabama Secretary of State business name search to confirm your desired LLC name is available. Alabama requires the name to include "LLC", "L.L.C.", or "Limited Liability Company" and prohibits names that imply a banking, insurance, or government function. If you're not ready to file immediately, reserve the name for $25 — it's held for one year.
- 2Appoint an Alabama registered agent
Your registered agent must have a physical street address in Alabama (no PO boxes) and be available during business hours to accept legal service. You can serve as your own agent if you live in Alabama, but most owners use a commercial registered agent service for privacy and to keep their home address off public filings.
- 3File the Certificate of Formation
File online through the Alabama SOS portal. The filing fee is $200, and standard processing is 1–3 business days. The Certificate of Formation requires the LLC name, registered agent details, principal office address, the names of organizers, and whether the LLC is member-managed or manager-managed.
- 4Draft an Operating Agreement
Alabama doesn't require you to file an Operating Agreement, but you absolutely should have one. It defines membership interests, profit/loss allocations, voting rights, and what happens when a member dies, withdraws, or is bought out. Banks routinely ask for a copy when you open a business account.
- 5Apply for a federal EIN
Get an EIN free from the IRS at irs.gov — the application takes 10 minutes online. You'll need an EIN to open a business bank account, register with the Alabama Department of Revenue, and file the BPT return. Single-member LLCs without employees can technically use the owner's SSN, but get an EIN anyway.
- 6Register with the Alabama Department of Revenue
Sign up through the My Alabama Taxes (MAT) portal for any tax accounts you need: sales and use tax (if you sell taxable goods), withholding tax (if you have employees), and the BPT account (every Alabama LLC needs this). Sales tax licensing through MAT is free.
- 7Get a local business license and file your first BPT return
Most Alabama cities require a separate municipal business license — Birmingham, Mobile, Huntsville, and Montgomery all do. Fees are usually based on gross receipts. Then calendar your first BPT return: it's due April 15 of the year after formation, with a $50 minimum tax.

Alabama LLC: frequently asked questions
How much does it cost to start an LLC in Alabama?
The Alabama Secretary of State charges $200 to file the Certificate of Formation. There's no annual report fee, but every Alabama LLC must file a Business Privilege Tax return every April 15 with a $50 minimum tax. So the realistic year-one cost is $250, and ongoing yearly cost is $50 plus any registered-agent service fee ($99–$300).
How long does it take to form an LLC in Alabama?
Online filings through the Alabama SOS portal typically approve in 1–3 business days. Mail-in filings can take 2–4 weeks. Alabama doesn't offer a separate expedited tier — online is the fastest option.
Does Alabama require an LLC annual report?
Not at the Secretary of State level — Alabama is one of the few states with no SOS annual report. However, the Business Privilege Tax (BPT) return functions as a de facto annual filing. It's due every April 15 and carries a $50 minimum tax even if your LLC made no money.
What is the Alabama Business Privilege Tax for an LLC?
The BPT is a state-level tax on the privilege of doing business in Alabama. For most small LLCs, the minimum is $50 per year. The actual tax is calculated based on the LLC's federal taxable income apportioned to Alabama, but the $50 minimum applies regardless of size or revenue. The return is due April 15.
Do I need an Alabama business license in addition to the LLC?
Almost always. The Certificate of Formation creates the LLC at the state level, but most Alabama cities require a separate municipal business license. Birmingham, Mobile, Huntsville, and Montgomery all have their own licensing requirements, usually based on gross receipts. Check with your city clerk for fees and renewal dates.
Can a non-resident form an LLC in Alabama?
Yes. Alabama has no residency requirement for LLC members or managers. You only need to appoint a registered agent with a physical Alabama street address. Non-residents commonly use a commercial registered agent service to satisfy this requirement.
Is a single-member LLC recognized in Alabama?
Yes. Alabama recognizes single-member LLCs (SMLLCs) and they enjoy the same liability protection as multi-member LLCs at the state level. For federal tax purposes, the IRS treats an SMLLC as a "disregarded entity" by default — its income flows through to the owner's personal return on Schedule C.
What's better in Alabama: LLC or sole proprietorship?
For most small businesses with any meaningful liability exposure, the LLC wins. A sole proprietorship costs nothing to start but offers zero personal liability protection — your personal assets (home, savings, car) can be reached by business creditors. The Alabama LLC's $200 setup and $50/year ongoing cost is cheap insurance against that risk.
