A Series LLC in Alabama lets you house multiple business ventures or investment properties under a single parent LLC, with each “series” holding its own assets and liabilities walled off from the others. The structure is authorized under Title 10A, Chapter 5A, Article 11 of the Alabama Code, part of the Alabama Limited Liability Company Law of 2014. To get the internal liability shield the statute promises, you have to do three specific things: designate the entity as a Series LLC on the Certificate of Formation, include the right language in your operating agreement, and keep each series’ records genuinely separate. Miss any one, and the walls between series collapse.
What a Series LLC Is Under Alabama Law
Section 10A-5A-11.01 authorizes a parent LLC to establish one or more “designated series of assets,” each with its own rights, powers, duties, and business purposes. A series can carry on any lawful activity, whether or not for profit. The operative word is “designated.” A series has to be intentionally created through the LLC’s operating agreement. You cannot claim series treatment for a line of business just because you happen to run it separately.
The practical draw is real: instead of forming five separate LLCs to hold five rental properties, you can form one Series LLC and put each property in its own series. One filing, one registered agent, one annual compliance track. The trade-off is that the protections only work if you follow the rules closely, and the structure carries some tax and interstate uncertainty that separate LLCs don’t.
The Three Conditions for Inter-Series Liability Protection
The liability shield between series depends on Section 10A-5A-11.02(b). If all three conditions are satisfied, debts of one series cannot be enforced against another series or the parent LLC, and vice versa.
- Separate records. Each series must account for its assets separately from the parent LLC and every other series.
- Operating agreement language. The operating agreement must include a statement acknowledging the liability limitations between series.
- Certificate of formation language. The certificate filed with the state must state that the LLC may have one or more series of assets subject to those liability limitations.
Fail on any one, and a court will treat the entity as a conventional LLC, with all assets potentially exposed to any series’ creditors. The record-keeping condition is where most owners slip, but the two paperwork conditions can be fixed on the front end and then have to stay fixed.
Forming a Series LLC in Alabama
Formation runs through the Alabama Secretary of State. You file a Certificate of Formation and pay a $200 filing fee.
The Secretary of State’s form includes a checkbox to designate the entity as a “Series LLC complying with Title 10A, Chapter 5A, Article 11.” Checking it satisfies the certificate condition in Section 10A-5A-11.02(b)(3). Skip the box and you have a regular LLC; you cannot bolt series protections on later without amending the certificate.
Two more items round out formation:
- Registered agent. Every Alabama LLC must maintain a registered agent with a physical address in the state to accept legal documents. Letting the registered agent lapse can trigger administrative dissolution.
- EIN. The IRS requires an Employer Identification Number if you will hire employees or open a business bank account. For a Series LLC, many banks also require a separate EIN for each series before they will open distinct accounts, which reinforces the financial separation courts look for.
Business Privilege Tax
Alabama historically required every LLC to file a Business Privilege Tax Return and pay a minimum $100 tax shortly after formation. Under Act 2022-252, for taxable years beginning after December 31, 2023, any entity whose calculated business privilege tax comes to $100 or less is fully exempt and does not need to file a return. Most newly formed LLCs with modest net worth fall under this exemption. Entities with higher net worth still owe the tax and must file annually until the LLC is formally dissolved or withdrawn.
Drafting the Operating Agreement
Alabama does not legally require an LLC to have a written operating agreement. Under Section 10A-5A-1.08, the operating agreement governs the relationship among members and between the members and the LLC; where the agreement is silent, state default rules fill the gap. For a regular LLC, running without one is risky but survivable. For a Series LLC, it can be fatal to the liability shield.
Section 10A-5A-11.02(b)(2) requires the operating agreement to contain a statement acknowledging the liability limitations between series. Without that language, the internal walls collapse no matter how carefully you keep the books. A written, properly drafted operating agreement is effectively mandatory here.
At minimum, a Series LLC operating agreement should cover:
- How each series is created and dissolved, and who has authority to make those decisions.
- Whether each series has its own members, how profits and losses are split within each series, and whether members of one series have rights in another.
- Voting rights and management authority for each series, including any decisions requiring parent-level or cross-series approval.
- Explicit cross-liability language confirming that each series’ obligations are confined to its own assets. Lenders and landlords often want to read this language before signing with an individual series.
Courts routinely look to the operating agreement when evaluating whether a series was genuinely run as a separate operation. The more detailed and consistently followed the agreement, the harder it becomes for a creditor to argue the structure was just paperwork.
Keeping the Liability Shield Intact
Under Section 10A-5A-11.02(a), debts incurred by one series can only be enforced against that series’ assets. Creditors of the parent LLC cannot reach a series’ assets, and creditors of one series cannot tap another’s. This internal shield is what distinguishes a Series LLC from just forming several separate LLCs. The external shield, protecting individual members from personal liability for the entity’s debts, works the same way it does for any Alabama LLC.
Commingling funds is the fastest way to lose the internal protection. If Series A’s rental income flows through the same bank account as Series B’s consulting revenue, a court has grounds to treat both as a single pool. Each series should have its own bank account, its own books, and its own contracts.
Section 10A-5A-11.03 allows assets to be recorded under either the series’ name or the parent LLC’s name, as long as the records can “reasonably identify” which assets belong to which series. Identification can be by specific listing, category, percentage, or any objective method. Holding assets directly in each series’ name reduces ambiguity.
Beyond the statutory conditions, courts evaluating whether to pierce an LLC’s liability protections look at whether the entity was adequately capitalized, maintained its own records, and operated as a genuine business rather than a shell. Those factors apply at both the parent level and the series level. A series that exists only on paper, holds no real assets, and has no independent activity is an easy target for a creditor trying to collapse the structure.
Management Flexibility Across Series
A Series LLC can be member-managed or manager-managed, like any Alabama LLC. Where it gets more useful is that each individual series can have its own management arrangement. One series might be member-managed by a subset of the LLC’s owners while another is run by a hired manager with no ownership stake. This flexibility fits well when different series involve different business activities or investment strategies.
The operating agreement should document who manages each series, what decisions they can make independently, and which decisions require broader approval. If one person makes every decision for every series with no documented distinction, a court may conclude the series were not genuinely independent, which invites the same veil-piercing arguments that sloppy records do.
Federal Tax Treatment Is Still Uncertain
Federal tax treatment of Series LLCs sits in a gray area. In 2010, the IRS issued proposed regulations that would treat each series within a Series LLC as a separate entity for federal income tax purposes, with each series independently classified as a partnership, a disregarded entity, or an association taxable as a corporation. As of 2026, those regulations have never been finalized.
In practice, some Series LLCs report all income and expenses under the parent’s single EIN, while others file separate returns for each series. Neither approach has been definitively blessed or rejected. Work with a tax professional who tracks the current status of the proposed regulations before deciding how to report. Getting this wrong can mean amended returns, penalties, or an audit years later.
Operating in Other States
This is where the Series LLC runs into a hard practical limit. Not every state recognizes Series LLCs, and the consequences of operating in a non-series state are genuinely uncertain.
When an Alabama Series LLC does business in another state, it typically has to register as a foreign LLC. In states with their own series statutes, that process is relatively straightforward. In states without series legislation, several problems appear:
- Some states may accept a foreign qualification from the parent LLC but have no mechanism to register individual series separately. Others may not know what to do with a series filing at all.
- If a lawsuit arises in a state that does not recognize series structures, the court may refuse to honor the liability walls, and the entire entity could be treated as one pool of assets.
- Some states require each series doing business within their borders to register and pay state taxes separately, even after the parent LLC has qualified.
Series LLCs have not been widely litigated, so there is little case law establishing whether an out-of-state court must respect another state’s series protections. If your operations will cross state lines, weigh whether separate LLCs, one in each state, offer more reliable protection than a single Alabama Series LLC.
Dissolving a Series or the Whole LLC
Parent LLC dissolution is governed by Section 10A-5A-7.01, which lists four triggering events: an event specified in the operating agreement, unanimous member consent, loss of the last member (unless the remaining interest holders agree in writing within 90 days to continue and appoint a new member), or a court order finding it no longer reasonably practicable to carry on. Once dissolution is triggered, the LLC enters winding-up under Section 10A-5A-7.02: collecting assets, settling debts, distributing remaining property, and filing a statement of dissolution with the Secretary of State if desired.
One advantage of the Series LLC structure is that individual series can be dissolved independently without shutting down the parent LLC or affecting other series. Article 11 includes dedicated provisions for series dissolution, covering triggering events, winding up, known and unknown claims, and distribution of the series’ assets. A series’ own assets must satisfy its liabilities before any remainder goes to that series’ members. The operating agreement should spell out distribution priority and creditor notification.
If the parent LLC is dissolved, every associated series terminates with it unless the operating agreement provides a mechanism for transferring a series’ assets and operations to another entity. Planning for that in advance is the kind of detail that separates a well-structured Series LLC from one that creates more problems than it solves.
