Every Type of LLC Structure Explained (2026)
Most people think there's just one kind of LLC. There are actually eight genuinely distinct structural variations, each solving a different problem — ownership count, management control, liability isolation between properties, privacy, or professional licensing. Here's the complete map, and how to tell which one you actually need.
LLC structures fall into eight main types: Single-Member LLC (one owner), Multi-Member LLC (two or more owners), organized as either member-managed or manager-managed. Beyond ownership count, structural variations include the Series LLC (multiple isolated "child" LLCs under one parent, available in about 20 states), the PLLC (Professional LLC, required for certain licensed professions like law and medicine), the Anonymous LLC (keeps ownership off public record, available in states like Wyoming and Delaware), and the Holding Company LLC structure (a parent LLC owning subsidiary LLCs to isolate risk). Most LLC owners only need a standard single- or multi-member LLC — the specialized structures solve specific problems most businesses don't actually have.

Ownership Structures: Single vs. Multi-Member
The most basic structural choice among LLC structures is ownership count. A Single-Member LLC has exactly one owner, taxed by default as a disregarded entity — the IRS treats it as if it doesn't exist separately from you for tax purposes, though it still provides full liability protection. A Multi-Member LLC has two or more owners, taxed by default as a partnership, requiring a genuinely more detailed operating agreement covering ownership percentages, decision-making authority, and profit distribution.
Management Structures: Member vs. Manager-Managed
Independent of ownership count, every LLC also chooses a management structure. Member-managed means the owners themselves run daily operations — the default for most small LLCs. Manager-managed designates one or more managers (who may or may not be owners) to run the business, useful when some owners are passive investors who don't want day-to-day involvement, or when a multi-member LLC wants centralized decision-making rather than requiring every member's sign-off.
Series LLC: Isolating Risk Across Multiple Properties
A Series LLC is a genuinely distinct structure: one parent LLC creates multiple "child" series underneath it, each with its own assets, liabilities, and members — and critically, a lawsuit against one series generally can't reach the assets of another. This is popular among real estate investors holding multiple properties, since it can avoid forming and maintaining a separate full LLC for each one. Only about 20 states currently recognize Series LLCs, so availability depends entirely on where you form.
PLLC: For Licensed Professionals
A PLLC (Professional LLC) is a required structure in many states for licensed professionals — doctors, lawyers, accountants, architects — whose profession carries its own regulatory oversight. A standard LLC often isn't legally available to these professions in states that mandate the PLLC structure instead; the core difference is that a PLLC generally doesn't shield you from your own malpractice liability, only from the business debts and other members' malpractice.
Anonymous LLC: For Privacy
An Anonymous LLC keeps member names off the state's public record — available in a handful of states, most notably Wyoming, Delaware, New Mexico, and Nevada. This isn't a separate legal entity type so much as a privacy feature available in specific states, typically achieved by using a registered agent's information rather than the owner's on the public filing.
Holding Company LLC Structure
A Holding Company LLC structure uses a parent LLC to own one or more subsidiary LLCs, isolating risk between different business lines or asset classes under one ownership umbrella. This is genuinely more complex to set up and maintain than a single LLC, and is typically only worth it once a business has grown enough to justify the added structure.
LLC Structures: Which One Do You Actually Need?
Most people reading about LLC structures actually need the simplest option. If you're a solo founder with no employees requiring licensure, a standard Single-Member LLC covers you completely. If you have co-owners, a standard Multi-Member LLC with a solid operating agreement is almost always sufficient. The specialized structures — Series, PLLC, Anonymous, Holding Company — solve specific problems (multiple properties, professional licensing, privacy, multi-business risk isolation) that most new LLC owners genuinely don't have yet.

| Structure | Best For | Availability |

Ahmad Adil's Take: I see a lot of new LLC owners get pulled toward the exotic structures — Series LLCs, Anonymous LLCs, holding companies — before they've even formed their first standard LLC. There's nothing wrong with those structures, but they exist to solve specific, real problems, not to sound more sophisticated. Start with the simplest structure that actually fits your situation today, and graduate to something more specialized when a genuine, specific need for it shows up — not before.

About Ahmad Adil → Compare States →Northwest Registered Agent Review — Company Overview
In this Northwest Registered Agent review, we cover the company that most independent evaluators — including LLCUniversity, LLC.org, Startup Savant, and LLC Starters — consistently rank as the top overall LLC formation and registered agent service. Northwest Registered Agent was founded in 1998 in Spokane, Washington as a registered agent service before expanding into full LLC formation. It remains a privately held, family-owned company with real offices in all 50 states and DC.
Their tagline — "We're just not annoying" — is a direct shot at the rest of the industry, and it's largely accurate. Where most formation services use confusing tier structures, aggressive checkout upsells, and post-formation spam calls from selling your data to third-party marketers, Northwest does none of those things. That's the core of their value proposition, and it holds up under scrutiny.
Northwest Registered Agent Review — Complete 2026 Pricing
Northwest's pricing model is the most transparent in the industry. One package, one price, everything disclosed upfront. Here is the complete breakdown for the Northwest Registered Agent review.
What's Included in Northwest's $39 — Full Feature List
The most important part of any Northwest Registered Agent review is understanding exactly what comes with the $39 fee — because it's substantially more than what "$0 formation" competitors include in their base price.
Northwest Registered Agent Review — Pros and Cons
Here is the complete honest assessment from our Northwest Registered Agent review — the genuine advantages and the real documented limitations, in equal detail.
What Northwest Does Exceptionally Well
- Privacy by Default — Northwest's own address appears on all public state filings instead of yours. This is a genuine differentiator. No other major formation service does this as a standard default. Your home address never enters public records.
- No data selling — Northwest explicitly does not sell customer data to third-party marketers. You will not receive the wave of spam calls and emails that commonly follow formation with Bizee or other services.
- Zero upsells at checkout — the $39 checkout has no pop-ups, no countdown timers, no "are you sure you don't need the premium plan?" The process is clean and honest.
- Corporate Guides — dedicated US-based human advisors with real knowledge. Everyone at Northwest does customer service — there's no separate sales team. You can reach someone who knows what an LLC is and can answer specific state questions.
- Same-day filing — in most states, your documents are submitted to the state the same business day you order. No processing queue, no rush fee.
- $125/yr flat RA — price-locked — the renewal price never increases. After year one free, you pay $125/yr forever. ZenBusiness charges $199/yr; LegalZoom charges $249/yr for equivalent service.
- Error-free guarantee — if Northwest makes a filing error, they file all corrections at no cost. This is explicitly stated in their terms.
- Business Identity suite (Jan 2026) — domain, website hosting, business email, phone number all included at no extra charge while your RA remains active.
- Non-US residents served — Northwest can form a Delaware LLC or C-Corp for non-US residents without an SSN, using their own address throughout the process.
Real Limitations You Should Know
- No weekend support — M–F 9am–8pm ET only. If you have an urgent question on Saturday, you're waiting until Monday. This is the most commonly cited limitation in user reviews.
- No live chat — phone and email only. ZenBusiness has 7-day live chat. Northwest does not.
- Business Identity add-ons are hard to cancel — multiple documented user complaints about difficulty canceling the domain, email, and web hosting services when they decide to switch providers. Domain transfers in particular have taken weeks. This is the most serious documented problem in recent reviews.
- EIN not included — requires a $50 add-on. However, the EIN is always free at IRS.gov and takes 10 minutes, so this is a convenience charge rather than a genuine gap.
- Basic dashboard — functional but not modern. No mobile app. If you're used to polished SaaS interfaces, Northwest's utilitarian dashboard will feel dated.
- Not for complex structures — not well-suited for LLCs with unusual ownership structures, multi-class membership interests, or complex formation needs. An attorney is recommended in those cases.
- No banking partnership — no integrated business bank account offering. You'll need to open your business account separately (recommended: Mercury, Chase, or Relay).
- Core RA cancellation requires phone call — you cannot cancel the RA service entirely through the dashboard; you must call. Some users find this inconvenient.
- Small Trustpilot sample — only ~222 reviews vs ZenBusiness's 30,000+. The small sample makes the Trustpilot score less representative and more volatile.
LLC School Score Breakdown — Northwest Registered Agent
Here's how we rated Northwest Registered Agent across the five criteria that matter most when choosing an LLC formation and registered agent service for our Northwest Registered Agent review.
Scores are LLC School's independent assessment. The 4.5 for Support reflects the M–F-only hours and no live chat — quality of support when reached is 5.0, but availability limitations reduce the category score.
Northwest Registered Agent Review — Real Complaints Addressed
Every honest Northwest Registered Agent review must address the documented complaints. We've reviewed BBB complaints, Trustpilot reviews, and Reddit discussions to identify the patterns. Here's what the real issues are — and how serious they are.
Multiple users on Trustpilot and Reddit have documented difficulties when trying to cancel or transfer the domain, email hosting, and web hosting services included in the Business Identity suite. Specific documented issues include:
— Domain transfers taking weeks instead of ICANN's required 5 days
— Billing continuing after cancellation was initiated
— "Cancel" button not functioning in the dashboard for some services
— Credit card cannot be removed from one service without removing it from all
Important context: These complaints specifically relate to the Business Identity add-on services — NOT the core registered agent and LLC formation service. Users who have no complaints about formation quality or RA quality often report the Business Identity issues. If you want to avoid this problem entirely: cancel the Business Identity free trials immediately after formation if you don't intend to use them long-term. Or simply don't opt into them during checkout.
Northwest's response pattern: In documented BBB complaints, Northwest's support team acknowledges and resolves billing issues when escalated. The resolution rate is high — but the friction to get there is real.
Northwest's Trustpilot profile shows approximately 57% 5-star reviews and 33% 1-star reviews — a bimodal distribution with very little middle. This pattern is common in service industries where: (1) happy customers rarely leave reviews, (2) frustrated customers are highly motivated to review, and (3) former employees or competitors can influence small review pools.
In contrast, ZenBusiness has 30,503 reviews. Bizee has 25,400+. LegalZoom has 31,000+. With 222 reviews versus their competitors' 25,000–31,000, Northwest's Trustpilot score reflects a sample that is less than 1% of the size of their competitors' review pools.
When you read the 1-star reviews, most fall into two categories: (1) Business Identity add-on billing/cancellation issues (same complaint as above), and (2) customers who had filing errors or complex situations handled poorly. The core RA and standard LLC formation service receives consistently high marks. The BBB rating is A+ with most complaints resolved to customer satisfaction.
Recommendation: Don't let the Trustpilot score sway you disproportionately given the sample size. Do read the specific 1-star reviews to understand what the failure modes are — mainly Business Identity and unusual filing situations.
Some users report difficulty reaching support — calling multiple times without getting through, or not receiving timely email responses. These complaints exist but are less frequent than the Business Identity complaints.
The context: Northwest's support is M–F 9am–8pm ET only. No weekends. No live chat. If you call during peak hours or near closing, wait times can be longer. For users accustomed to ZenBusiness's 7-day live chat, the contrast is real.
When you do reach a Corporate Guide, the quality is universally praised — knowledgeable, helpful, no scripts, no upsells. The issue is availability windows, not quality. For most LLC owners with non-urgent questions, email response within a business day is acceptable. For urgent situations requiring same-day answers on a Saturday, Northwest is the wrong choice — ZenBusiness is better.
Practical tip: Call before 3pm ET on weekdays for the best chance of immediate connection. For non-urgent questions, email works reliably within 24 hours during business days.
Northwest is not designed for complex business structures. Complaints about support quality are most common from users trying to form something other than a standard LLC or S-Corp — multi-class membership interests, unusual manager arrangements, professional LLCs with regulatory requirements, or complex operating agreements with custom provisions.
For these situations, Northwest's service reaches its limits. Their operating agreement template is a solid starting point for simple single-member or standard two-member LLCs, but it's a template — not a custom-drafted document. Northwest's Corporate Guides can answer basic questions but cannot provide legal advice.
When to use an attorney instead of Northwest: Multi-member LLC with complex profit-sharing arrangements (non-proportional to ownership), manager-managed LLC where the manager agreement needs custom provisions, LLCs that will raise outside investment, professional LLCs (PLLCs) for licensed professionals, or any formation where you need actual legal advice about structure rather than just filing paperwork. For a standard single-member or two-member LLC, Northwest handles everything you need without an attorney.
