Alabama LLC Requirements: Compliance & Annual Rules

Once your Alabama LLC exists, the work is not over. Alabama imposes ongoing requirements that catch business owners off guard, and missing them can cost you your liability protection or your good standing with the state. This guide covers what every Alabama LLC owner must do to stay compliant, the registered agent rules, the Business Privilege Tax, annual filings, licenses, and record-keeping. If you have not formed your LLC yet, start with our step-by-step guide on how to form an LLC in Alabama, then come back here for what happens next.

At Colvin & Sawyer Law Offices, Christopher Colvin helps entrepreneurs across Birmingham, Mountain Brook, Hoover, Vestavia Hills, and throughout Alabama form their LLCs correctly and stay compliant year after year.

First, Make Sure Your LLC Was Formed Correctly

Most compliance problems start at formation. Alabama requires a Certificate of Formation filed with the Secretary of State and recorded with the county probate court, a two-step process most online filing services miss. If only the first step was done, your LLC may not be properly formed, which undermines everything below. We cover the full process, name reservation, registered agent, both filings, and the operating agreement, in our companion guide:

Post-Formation Requirements

EIN and Business Bank Account

Get a federal Employer Identification Number (EIN) from IRS.gov, free and takes minutes. Open a dedicated business bank account in the LLC's name. Keeping personal and business finances separate is essential for maintaining your liability protection and is a basic compliance requirement for any LLC.

Alabama Business Privilege Tax

Every Alabama LLC owes the annual Business Privilege Tax, minimum $100, maximum $15,000 based on net worth apportioned to Alabama. The initial BPT return is due within 2.5 months of the date of formation, a deadline many new business owners miss. Subsequent returns are due with the federal return (April 15 for most LLCs). See: Alabama Business Privilege Tax.

Local Business Licenses

Alabama does not have a statewide business license, but most cities and counties require their own licenses for businesses operating within their jurisdiction. Check the requirements for the city and county where your business operates.

Registered Agent, Ongoing

You must maintain a current registered agent with a valid Alabama address at all times. If your registered agent changes, you must file an update with the Alabama Secretary of State. Failure to maintain a registered agent can result in loss of good standing.

Record Keeping and Separate Finances

Alabama does not mandate a specific record-keeping format, but maintaining clean records is what actually preserves your liability shield. Keep the operating agreement, formation documents, EIN letter, tax filings, and major decisions in one place. Most importantly, never commingle funds: run all business income and expenses through the LLC's own bank account. Mixing personal and business money is the single most common way owners accidentally expose themselves to personal liability, a problem lawyers call piercing the corporate veil.

Taxes Beyond the Business Privilege Tax

By default a single-member Alabama LLC is taxed as a sole proprietorship and a multi-member LLC as a partnership, with profits passing through to the owners' personal returns. An LLC can also elect S-corporation or C-corporation tax treatment, which can change how much self-employment tax you pay. Which election makes sense depends on your income and goals, and it is worth coordinating with an attorney and accountant rather than guessing.

Alabama LLC Annual Compliance Checklist

Every Alabama LLC owner should run through this list each year to stay in good standing:

• File the annual Business Privilege Tax return (due with your federal return)
• Confirm your registered agent is current and the Alabama address is valid
• Renew city and county business licenses
• Keep business and personal finances fully separate
• Update the operating agreement if ownership or management changed
• File any Secretary of State updates if your address or agent changed
• Keep tax filings and major decisions documented

Common Alabama LLC Compliance Mistakes

These are the failures we most often see, and each one can cost an owner their protection or their good standing:

• Missing the initial Business Privilege Tax return, due just 2.5 months after formation, before most owners even think about taxes
• Letting the registered agent lapse, which can trigger loss of good standing
• Skipping local business licenses, assuming the state filing was enough
• Commingling funds, using one account for personal and business spending
• Never adopting an operating agreement, leaving Alabama's default rules in control
• Ignoring an inactive LLC, which still owes the Business Privilege Tax until it is formally dissolved
