What an LLC really does, how to form one in your home state, and the habits that keep your liability shield intact.
An LLC — limited liability company — is a business structure created under state law that does two main jobs. First, it puts a legal wall between the business and you personally. If the business is sued or runs up debts it can't pay, the people it owes generally have to look to the business's own assets, not your house, your car, or your personal savings. That separation is the whole point of the 'limited liability' in the name. Second, by default an LLC is 'pass-through' for taxes: the business itself usually pays no separate federal income tax, and the profits and losses flow through to the owners' personal returns. You get the liability protection of a corporation without a second layer of corporate tax.
It helps just as much to know what an LLC does NOT do. It will not protect you from the consequences of your own actions — if you personally injure someone or do the negligent work that causes the harm, you can still be on the hook even though an LLC's name is on the door. It will not erase a personal guarantee: when a landlord or a bank asks you to personally sign for a lease or a loan, you've agreed to pay it yourself, LLC or not. And it is not a tax dodge or a way to hide who owns the business. Think of an LLC as a sturdy fence around the business, not an invisibility cloak around you.
You'll see a lot of advice online telling small-business owners to form in Delaware, Wyoming, or Nevada for the low fees or business-friendly courts. For a company that operates in one place — a freelancer, a local shop, a contractor working in your own town — that advice usually creates more cost and paperwork than it saves. The reason is simple: an LLC is registered in the state where it's formed, but if it actually does business in another state, that state generally wants it registered there too, as a 'foreign LLC.'
So if you form in Delaware but run the business from your home state, you typically end up paying to register in Delaware AND registering as a foreign LLC where you actually work — two sets of fees, two registered agents, two annual filings, for one small business. For most owners whose customers and work are all in one state, forming in your home state is the cleaner, cheaper path. The out-of-state-formation playbook is built for companies with investors, multi-state operations, or specific legal reasons to want another state's courts — not for the typical one-location LLC.
Your LLC needs a name that your state will accept. In every state the name has to be distinguishable from other businesses already on file, and it usually has to include a tag like 'LLC' or 'Limited Liability Company' so the public knows it's a limited-liability entity. States run a free business-name search on their Secretary of State (or equivalent) website, so you can check availability before you commit to signage, a logo, or a domain.
You also have to name a registered agent. A registered agent is simply the person or company officially designated to receive legal papers — a lawsuit, a subpoena, a state notice — on the LLC's behalf, at a real street address in the state during normal business hours. Every state requires one. You can usually be your own registered agent if you have a fixed address in the state and don't mind your name and address being part of the public record, or you can hire a commercial registered-agent service for an annual fee. The practical reason this matters: if someone sues your business and your registered-agent information is out of date, you can miss the notice entirely and lose by default without ever knowing a case was filed.
The document that actually brings your LLC into existence is usually called the Articles of Organization (some states call it a Certificate of Formation or Certificate of Organization). You file it with the state — almost always the Secretary of State — and once it's accepted, the LLC legally exists. The form itself is short: typically the LLC's name, its address, its registered agent, and who's organizing it. Many states let you file online and approve it within days.
The filing fee is where states differ the most, and the range is wide. This is a per-state number, so rather than guess, check your state's exact fee in the 'your state' panel above, and you can line up all 50 in the comparison table on this page. A few states add one more step: a publication requirement, meaning you have to publish a notice of your new LLC in a local newspaper for a set period and then file proof. It's not nationwide, but if your state is one of the handful that requires it, skipping it can leave your LLC out of good standing — so confirm your state's rule before you assume you're done after filing.
An operating agreement is the internal rulebook for the LLC: who owns what percentage, how decisions get made, how money comes in and goes out, and what happens if an owner wants to leave or the company winds down. Most states do not require you to file one, and a few don't strictly require you to have one at all. It's still one of the most valuable documents you can create, and that's true even for a single-member LLC with no partners to argue with.
Two reasons stand out. First, it reinforces the liability shield. One of the strongest arguments someone can make to 'pierce' your LLC and come after you personally is that the LLC was never really a separate entity — just you under a different name. A signed operating agreement that you actually follow is concrete evidence that the business is a real, governed entity. Second, it lets you set your own rules instead of defaulting to your state's generic fallback statutes, which may not match how you'd want things handled. Writing it down now is far easier than reconstructing intentions later, especially if you ever add a partner or sell.
An EIN, or Employer Identification Number, is the business's federal tax ID — the company's equivalent of a Social Security number. You'll generally need one to open a business bank account, hire employees, or have the LLC taxed as a corporation, and many single-member owners get one simply to keep their personal SSN off business paperwork. The process is genuinely quick: the IRS issues EINs directly, online, and the application takes minutes for an eligible applicant with a U.S. address.
Here's the part worth shouting: getting an EIN from the IRS is free. There is no charge, ever, from the government. Plenty of look-alike websites will offer to 'obtain your EIN' for a fee, dressing up a free federal service as a paid one. You don't need them. Go to the IRS's own application (linked in the sources below), and don't pay a third party for a number the IRS hands out at no cost.
Forming the LLC and getting a license are two different things, and people mix them up constantly. There is no general FEDERAL business license that every business needs — federal licensing only applies to specific regulated activities, like selling alcohol, firearms, or running certain transportation or broadcasting operations. What most small businesses actually need is a state and/or local license or permit to operate, and those requirements vary by where you are and what you do. Whether your state has a general business license, and what it costs, is a per-state detail — check your state's figure in the panel above, and confirm any city or county requirements with your local government.
On taxes, the default is the pass-through treatment described earlier: a single-member LLC is generally treated like a sole proprietorship and a multi-member LLC like a partnership, with profits flowing to the owners' personal returns. An LLC can also elect to be taxed as an S corporation, which some owners do to change how self-employment tax applies once profits reach a certain level — that's a judgment call worth running past a tax professional rather than a default to flip on day one.
Forming the LLC is the easy part; keeping it real is the ongoing work. Most states require some periodic upkeep — commonly an annual or biennial report and a renewal fee — to keep the LLC in 'good standing.' Miss those for too long and the state can administratively dissolve your LLC, which can pull the liability shield out from under you at the worst possible moment. The exact report and fee are state-specific, so calendar your state's deadline and treat it like the small recurring chore it is.
The bigger day-to-day job is keeping the business genuinely separate from you — what people mean by protecting the 'corporate veil.' That means a dedicated business bank account, paying business expenses from business money and personal expenses from personal money, signing contracts in the LLC's name, and not treating the company account like a personal wallet. When owners 'commingle' funds — running personal costs through the business or vice versa — they hand the other side the exact argument needed to ignore the LLC and reach the owner personally. The protection an LLC offers is real, but it largely depends on you actually behaving like the business is a separate thing.
Say a freelance graphic designer has been working as a sole proprietor and wants the liability separation of an LLC. The general path looks the same in most states: pick an available name, name a registered agent (often the designer's own in-state address), file the Articles of Organization and pay the state's filing fee, get a free EIN from the IRS, open a business bank account, and sign a short operating agreement — even though it's just one person. From then on, client contracts go out in the LLC's name and the business money stays in the business account. None of that requires a lawyer for a straightforward, one-person operation, which is why so many freelancers handle formation themselves.
It's worth getting professional help when the situation has more moving parts: multiple owners who need a real ownership and exit agreement, outside investors, employees, a regulated industry, plans to operate across state lines, or any meaningful personal assets you want carefully shielded. A licensed attorney in your state can tailor the operating agreement and check the formation; a CPA or tax professional is the right person for the S-corp question and your overall tax picture. If you're not sure whether your situation is the simple kind or the complicated kind, the do-i-need-a-lawyer tool can help you think through whether this is a do-it-yourself filing or a moment to talk to a licensed attorney in your state. This guide is general legal information, not legal advice, and the exact rules and fees depend on your state — so confirm the specifics with your state's official sources before you file.
This is the one-time fee your state charges to file the articles of organization that legally create an LLC, with the recurring annual or biennial report/franchise fee noted alongside. Each value is cited to the state statute or agency; a state with no sourced figure shows "Not yet sourced."
