the short version
- an LLC is a legal wall: if the business gets sued or can't pay its bills, creditors generally reach business assets, not your house, car, or personal savings.
- state filing fees run $35 to $500, with a national average around $132. most people spend $150–$500 all-in the first year.
- you can file it yourself in 15–30 minutes on your Secretary of State's website. the $300 "formation packages" are convenience, not necessity.
- your EIN (business tax ID) is free from the IRS and takes about five minutes. never pay for one.
- the thing that actually kills LLCs: forgetting the annual report. miss it and the state can dissolve you.
what an llc actually does
Here's the whole idea in one sentence: an LLC makes your business a separate legal person from you.
Without one, you and your business are the same entity in the eyes of the law — that's called a sole proprietorship, and it's what you automatically are the moment you take money for anything. It costs nothing and requires no paperwork, which sounds great until something goes wrong. If a client sues, or the business racks up debt it can't pay, there's no line between "the business's money" and "your money." Your savings, your car, potentially your home — all reachable.
An LLC draws that line. If the company gets sued or can't pay, creditors can generally only come after what the business owns. Your personal stuff stays on your side of the wall. That's the entire pitch, and for most people it's enough.
The second benefit is quieter but real: pass-through taxation. The LLC itself doesn't pay federal income tax. Profits flow to you and you report them on your personal return — so you're not taxed twice the way a traditional corporation is.
do you even need one yet?
Honest answer: not always. If you're freelancing occasionally with no employees, no physical premises, and low liability risk, a sole proprietorship plus good insurance may genuinely be fine for now. An LLC starts making sense when you have real revenue, real clients with contracts, employees, physical operations, or personal assets worth protecting. "I might start a business someday" is not a reason to spend $800 in California franchise tax this year.
what it really costs
This is where most articles get vague, so here are actual numbers.

what your EIN costs from the IRS
The state filing fee is the one-time cost to file your Articles of Organization — the document that creates the LLC. It ranges from about $35 (Montana) to $500 (Massachusetts), with the national average landing near $132. Mid-range states like Florida, Texas, and Colorado tend to sit somewhere around $125–$175.
The registered agent is a person or service with a physical address in your state who receives legal documents for the business. Every state requires one. You can usually be your own for $0 if you have a physical address there and can be available during business hours. A professional service runs roughly $50–$300 a year. The tradeoff is privacy (your home address becomes public record if you're your own agent) and reliability.
The annual report is the recurring fee to stay in good standing — most states collect it every year or two regardless of whether you made a dollar.
| cost | typical range | how often |
|---|---|---|
| state filing fee | $35 – $500 | once |
| registered agent | $0 (yourself) – $300 | yearly |
| EIN from the IRS | $0 | once |
| annual report | $0 – $300+ | yearly (varies) |
| operating agreement | $0 (template) – lawyer rates | once |
Franchise tax is the one that ambushes people. California charges $800 every year to every LLC organized or doing business there, even if the business is dormant — and the first-year exemption that existed from 2021–2023 has expired, so new California LLCs owe it in year one.
the two surprise costs
Publication requirements. New York, Arizona, and Nebraska require you to publish notice of your formation in local newspapers. In New York that means two newspapers for six consecutive weeks plus a $50 Certificate of Publication filing — and the newspaper costs alone run from roughly $150 to over $1,500 depending on your county. Get a quote before you file.
Filing in the "wrong" state. Every guide about Delaware and Wyoming skips this: if you form there but actually operate from home, you'll likely need to register as a foreign LLC in your home state too — meaning two sets of fees, two annual reports, and possibly two registered agents. For most small businesses, file in the state where you actually work.
the six steps
- Pick your state — almost always the one you live and work in. Don't get talked into Delaware unless you're raising venture capital.
- Choose a name and check it's available. Search your Secretary of State's business database. Most states require the name to include "LLC" or "Limited Liability Company" and to be meaningfully different from existing registered names. While you're there, check the domain and social handles too — and if the brand matters long-term, search the USPTO trademark database.
- Name your registered agent. Yourself (free, but your address goes on the public record) or a service ($50–$300/yr).
- File your Articles of Organization. This is the actual formation. It asks for basic information — LLC name, registered agent, business address. Most states let you do it online in 15–30 minutes. You'll get back a stamped copy and often a Certificate of Organization; keep both, because you'll need them for the bank.
- Get your EIN from the IRS — free, five minutes, at irs.gov. It's your business's tax ID number. Sites charging $75 for this are selling you a free government form.
- Write an operating agreement and open a business bank account. The operating agreement lays out ownership, profit splits, and what happens if someone leaves. Even single-member LLCs should have one — free templates exist, and banks and courts both like to see it.
the step people skip, and regret
That business bank account isn't optional bureaucracy — it's what keeps your liability wall standing. If you run business income through your personal checking, a court can decide the separation was never real and "pierce the corporate veil," which erases the protection you paid for. Separate accounts, always. Never pay personal expenses from the business account.
what happens after you file
Forming an LLC isn't one-and-done. The thing that quietly dissolves more LLCs than lawsuits is a missed annual report. States charge late fees and, if you keep ignoring them, administratively dissolve the company — meaning the protection you set up simply stops existing.
The moment your LLC is approved, put the annual report due date in your calendar with a two-week warning. That single action prevents the most common failure.
You may also need local business licenses or permits depending on your city and industry, and if you want S-corp tax treatment later (which can reduce self-employment tax once profits get meaningful), that's a separate IRS election — Form 2553 — layered on top of the LLC. It doesn't change your LLC under state law, only how the IRS taxes it.
about BOI reporting — this changed recently
You'll find lots of 2024-era articles insisting every LLC must file a Beneficial Ownership Information report with FinCEN. Under a March 2025 interim final rule, domestic US companies are no longer required to file. The Corporate Transparency Act wasn't repealed — the domestic requirement was suspended through rulemaking, so it could change again. Foreign-formed entities registered to do business in the US may still have obligations, and a few states (notably New York) run their own separate ownership-disclosure systems. Check FinCEN's official BOI page for current status rather than trusting an undated blog post.
the point of all this
An LLC is one of the rare adult tasks that's genuinely cheaper and easier than it sounds. It's a form, a fee, and a calendar reminder. The industry around it — the $500 packages, the urgent upsells, the "protect your assets NOW" ads — exists because the paperwork sounds intimidating enough that people will pay to avoid reading it.
You just read it.
Your next tiny step: search "[your state] Secretary of State business search" and type in the name you're considering. Free, takes two minutes, and tells you whether the name you're attached to is even available — which is the only thing that has to be true before any of the rest matters.
questions people actually ask
do i need a lawyer to form an llc?
For a straightforward single-member LLC, usually not — most people file directly with their state and never speak to an attorney.
Talk to one if you have business partners, outside investors, complicated ownership splits, or you're in a licensed or regulated industry. The cost of an hour of advice is small next to an ownership dispute later.
llc or sole proprietorship?
A sole proprietorship is free and automatic — you already are one if you've taken money for work. But there's no legal separation, so a lawsuit or unpaid business debt can reach your personal savings.
The LLC's entire value is that wall. If you have personal assets worth protecting or clients signing contracts, the wall is worth the filing fee.
should i form in delaware or wyoming?
Probably not. Those states are genuinely useful for companies raising venture capital or with complex ownership.
If you operate from your home state, forming elsewhere usually means registering as a foreign LLC at home too — two sets of fees, two annual reports, two registered agents. Most small businesses should file where they actually work.
does an llc lower my taxes?
By default, no. An LLC is a pass-through entity: profits land on your personal return either way, and you still owe self-employment tax.
Tax savings usually come later from electing S-corp treatment (IRS Form 2553), which can reduce self-employment tax once profits are high enough to justify running payroll. That's a separate election layered on top of the LLC, not a reason to form one.
how long does approval take?
It varies widely by state — some approve online filings same-day, others take a few weeks by mail. Many states offer expedited processing for an extra fee.
Your Secretary of State's website usually posts current processing times, which is the only number that's ever accurate.
