What Is an LLC?
An LLC, or Limited Liability Company, is a legal business structure that separates your personal assets from your business debts and liabilities. In simple terms, an LLC helps protect your house, car, and personal bank account if your business gets sued or owes money.
LLCs are popular because they combine liability protection with flexible management and relatively simple tax treatment. They work well for small businesses, freelancers, consultants, online businesses, real estate investors, and many growing companies.

Small businesses and flexible ownership structures |
Northwest has been forming LLCs and keeping them in good standing since 1998. The information on this page is based on that experience, plus current state filing requirements and IRS guidance.
What Does an LLC Do?
The main purpose of an LLC is to create a legal separation between you and your business. Without an LLC, there’s generally no distinction between personal and business liabilities. If your business is sued or can’t pay its debts, your personal assets could be at risk.
When you form an LLC with the state, it creates a separate legal entity for your business in the eyes of the law. That separation is what helps protect you personally. For example, if your LLC signs a contract, takes out a loan, or faces a lawsuit, the LLC—not you individually—is generally responsible for those obligations.
That doesn’t mean LLC protection is unlimited. Courts can sometimes “pierce the corporate veil” if owners commit fraud, mix personal and business finances, or ignore legal formalities. But for many small businesses, an LLC provides an important layer of protection.
How Does an LLC Work?
An LLC exists as its own legal entity after you file formation documents with the appropriate state agency, usually the Secretary of State.
Those formation documents are usually called “Articles of Organization,” although they may also be called “Certificate of Organization” or “Certificate of Formation,” depending on the state you’re filing in. Some states also require publication notices or additional filings.
Processing time runs from a few business days to a few weeks depending on the state. Once the state approves your Articles of Organization, your LLC officially exists.
Once the LLC is approved, the business can:
- Get an EIN from the IRS
- Sign contracts
- Hire employees
- Own property
- Apply for licenses
- Conduct business under the LLC name
- Open business bank accounts
Banks will usually require formation documents and an EIN before opening a business account.
The owners of an LLC are called members. Members can either manage the LLC themselves or appoint managers to run the company.
Types of LLCs
There are several types of LLCs categorized by everything from ownership and location to specific business purposes.
Here are the key LLC types for ownership structure and management:
Single-Member LLC
A single-member LLC has one owner.
Single-member LLCs are especially common for freelancers, consultants, and online businesses because it provides liability protection without adding much complexity.
Multi-Member LLC
A multi-member LLC has two or more owners.
Multi-member LLCs are commonly used by partnerships, family businesses, and startups with multiple founders.
Member-Managed LLC
In a member-managed LLC, the owners handle the day-to-day operations themselves.
This is the default structure in many states.
Manager-Managed LLC
In a manager-managed LLC, one or more designated managers run the business.
The managers may or may not be owners of the company.

What Are the Benefits of an LLC?
The main benefits of an LLC are personal liability protection, pass-through taxation, and flexible management. The same benefits as corporations, but without the board of directors, annual shareholder meetings, and other formalities.
Personal Liability Protection
The biggest advantage of an LLC is liability protection. If the business is sued or owes money, the owners are generally not personally responsible for business debts and obligations.
Flexible Tax Treatment
By default, LLCs usually have pass-through taxation. That means the profits and losses pass through the business and onto the owners’ personal tax returns, which avoids double taxation. An LLC may also choose to be taxed as an S corporation or C corporation in some situations.
Fewer Formalities
Compared to corporations, LLCs usually have fewer ongoing formal requirements. Many states require LLCs to file annual reports to remain in good standing.
However, most LLCs don’t need:
- Annual shareholder meetings
- Boards of directors
- Corporate minutes
Requirements vary by state, but LLCs are generally simpler to maintain than corporations.

Flexible Ownership Structure
LLCs can have:
- One owner
- Multiple owners
- Individuals as owners
- Companies as owners
- Foreign owners in many cases
All in all, LLCs are popular for good reason: they offer a lot of the protections and benefits of a corporation without the extra requirements. That flexibility makes LLCs useful for many different business types, especially small and medium-size business owners.

What Are the Disadvantages of an LLC?
Although LLCs are designed to help small business owners, they’re not perfect for every situation. Here are some potential disadvantages of an LLC:
Self-Employment Taxes
Many LLC owners pay self-employment taxes on business income. Depending on your income and business structure, this can become significant. To reduce that tax burden, some business owners elect S corporation taxation.
State Fees
Most states charge:
- Formation fees
- Annual report fees
- Franchise taxes
- Renewal fees
Some states like Montana and Kansas are very inexpensive for starting and maintaining an LLC. But if you’re forming an LLC in states like Massachusetts or California, you’ll be facing hundreds of dollars in annual fees and taxes.

Limited Outside Investment Options
LLCs can be less attractive to some investors compared to corporations, especially venture capital firms. Many startups that plan to seek institutional investment eventually convert to corporations.
How Are LLCs Taxed?
The IRS allows LLCs to choose how they want to be taxed in many situations. Here are some common choices
| Tax Treatment | How It Works | Common Users |
| Default Single-Member LLC Taxation | Income passes through to the owner’s personal tax return | Solo business owners, freelancers, consultants |
| Default Multi-Member LLC Taxation | Income passes through to members based on ownership percentages | Partnerships and multi-owner businesses |
| S Corporation Election | LLC elects S corp taxation to potentially reduce self-employment taxes | Growing businesses with consistent profits |
| C Corporation Election | LLC elects corporate taxation structure | Companies seeking outside investment or retained earnings |
Single-member LLCs are usually taxed like sole proprietorships
- Multi-member LLCs are usually taxed like partnerships
This is called pass-through taxation because profits pass through to the owners’ personal tax returns.
An LLC can also elect:
By default, the IRS does not treat LLCs as a separate federal tax classification. The right tax setup depends on income, payroll, ownership structure, and long-term business goals.
LLC taxation can become more complex as a business grows. See IRS guidance on LLC tax classification.
LLCs vs Other Business Entities
While LLCs are the most popular business entity among business owners, they’re not the only option.
Here’s how LLCs compare to other business entities:
LLC vs Sole Proprietorship
| LLC | Sole Proprietorship |
| Separate legal entity | No separate legal entity |
| Liability protection | No liability protection |
| State filing required | No state filing required |
| Business credibility | Less formal structure |
| Separate business name possible | Often tied to owner name |
A sole proprietorship is simpler to start, but it does not provide personal liability protection. For any business with financial exposure, an LLC is the better structure.

LLC vs Corporation
| LLC | Corporation |
| Flexible management | Formal corporate structure |
| Fewer formalities | More compliance requirements |
| Pass-through taxation possible | Double taxation possible |
| Easier for small businesses | Often preferred for investors |
| Members own the business | Shareholders own the business |
Many first-time business owners choose LLCs because they’re easier to maintain than corporations. LLCs work well for many small and medium-sized businesses because they balance protection and simplicity.
Here’s our deep dive comparing LLCs vs Corporations
Do You Need an Operating Agreement?
In most states, you are not legally required to have an operating agreement ,which is a document that explains how the LLC will operate.
It typically covers:
- ownership percentages
- voting rights
- profit distribution
- member responsibilities
- procedures for adding or removing members
Some states require operating agreements. Even when they’re optional, they’re usually a good idea—especially for multi-member LLCs where disagreements over ownership or decision-making can derail a business.
Does an LLC Protect You Personally?
An LLC can help protect personal assets, but it does not replace insurance, and it doesn’t protect owners who personally guarantee debts.
You can still be personally responsible if you:
- Personally guarantee debts
- Commit fraud
- Mix personal and business finances
- Fail to maintain the LLC properly
Keeping separate business and personal bank accounts is one of the most important steps for preserving LLC liability protection. An LLC is a legal structure, not a substitute for good business practices. Generally, it can protect your personal assets from business liabilities, but that protection is not automatic in every situation.
Who Should Form an LLC?
An LLC is strong fit for:
- Small business owners
- Freelancers
- Consultants
- Ecommerce businesses
- Landlords and real estate investors
- Agencies and contractors
- Online creators
- Side businesses
Any businesses with meaningful financial exposure—contracts, employees, physical locations, or client-facing service—benefits from the liability separation an LLC provides.
How to Start an LLC
The exact process varies by state, but forming an LLC usually involves these steps:
- Choose a business name
- Appoint a registered agent
- File Articles of Organization
- Create an operating agreement
- Get an EIN from the IRS
- Open a business bank account
- Obtain required licenses or permits
Once you’ve formed your LLC, you’ll have some ongoing maintenance to remain in good standing. Requirements vary by state, but most LLCs need a registered agent and require ongoing filings or annual reports to keep an LLC active and in good standing.
