Key Takeaway
5.5 million new business applications were filed in 2023, a record. Nearly 500,000 applications are still being filed every month in 2026. 85.8% of small businesses in America are one-person operations. And the majority of them are sole proprietorships, meaning their owners' personal homes, cars, and savings accounts are legally exposed to every business lawsuit and debt. An LLC fixes that. Here's exactly how to file one, what it costs, and whether you actually need one.
If you sell anything, consult for anyone, or freelance in any capacity, you are by default a sole proprietor. You didn't choose that. It happened automatically the moment you earned business income. A sole proprietorship means there is no legal separation between you and your business. If a client sues your business, they can come after your personal bank account, your house, and your retirement savings. If your business takes on debt it can't pay, creditors can pursue your personal assets.
An LLC (Limited Liability Company) creates a legal wall between your business and your personal life. Creditors can pursue the LLC's assets, but your personal property stays protected. That protection is the entire point, and it costs between $35 and $500 depending on your state, with an average filing fee of $132 nationwide. The process takes 15-30 minutes online in most states. There is no exam, no lawyer required for simple formations, and no minimum revenue threshold. If you have a business, you should probably have an LLC.
The LLC is the most popular business structure for new businesses by a significant margin, and for good reason: it combines the liability protection of a corporation with the tax simplicity of a sole proprietorship. You get the legal shield without the corporate formalities (board of directors, shareholder meetings, bylaws) that make corporations cumbersome for small operations. Here's the step-by-step process, with real costs and the traps most guides don't mention.
Step 1: Choose your state (it should be the one you live in)
Every "best state to form an LLC" article will tell you about Wyoming's low fees or Nevada's privacy protections or Delaware's business-friendly courts. Ignore all of them unless you actually live there. If you form an LLC in Wyoming but operate your business in Ohio, you'll need to register as a "foreign LLC" in Ohio anyway, paying filing fees in both states, maintaining a registered agent in both states, and filing annual reports in both states. You'll spend more money and create more paperwork than if you'd just filed in Ohio.
The rule is simple: form your LLC in the state where you live and do business. The cheapest states to file are Montana ($35), Kentucky ($40), and Arkansas ($45). The most expensive are Massachusetts ($500), Nevada ($425), Tennessee ($300), and Texas ($300). California adds an $800 annual franchise tax regardless of whether your LLC earns a single dollar, which makes it the most expensive state for small LLCs by a wide margin.
Step 2: Name your LLC and check availability
Your LLC name must be distinguishable from existing businesses registered in your state, and it must include "LLC" or "Limited Liability Company" (or an accepted abbreviation) at the end. Search your state's Secretary of State business database (every state has one online, and searches are usually free or $1) to confirm your desired name isn't taken.
If your preferred name is available, you can reserve it in most states for a small fee ($10-$50) while you prepare your paperwork. If you want to operate under a different name than your LLC's legal name (for example, registering "Smith Digital LLC" but doing business as "Smith Creative"), you'll need to file a DBA (Doing Business As), which costs $10-$100 depending on your state and county.
Step 3: File your Articles of Organization
This is the document that legally creates your LLC. Most states call it "Articles of Organization," though some use "Certificate of Formation" or "Certificate of Organization." It's a short form (typically one to two pages) that requires your LLC's name and address, your registered agent's name and address, whether the LLC is member-managed or manager-managed, and your signature.
File it online through your state's Secretary of State website. Pay the filing fee. In most states, your LLC is approved within 5-10 business days, though expedited processing (same day or next day) is available for an additional fee of $25-$100. That's it. Your LLC exists.
Member-managed vs. manager-managed: If you're the only owner and you'll be running the business yourself, choose member-managed. This is the default for single-member LLCs and means all owners participate in daily operations. Manager-managed is for LLCs where some owners are passive investors and a designated manager runs the business.
Step 4: Get your EIN and open a business bank account
An EIN (Employer Identification Number) is your LLC's tax ID. It's free from the IRS, takes five minutes to obtain online at irs.gov, and you need it before you can open a business bank account. You don't need employees to get an EIN. You need one simply to separate your business finances from your personal finances, which is the entire point of having an LLC.
Open a dedicated business checking account using your EIN and your Articles of Organization. Most banks offer free or low-cost business checking ($0-$15/month). Never mix personal and business funds. This is not optional advice; it's the foundation of your LLC's legal protection. If you use your personal account for business transactions, pay personal bills from your business account, or otherwise "commingle funds," a court can "pierce the corporate veil" and eliminate the liability protection you just paid to create. This is the single most common way LLC owners accidentally destroy their own legal protection.
Keeping separate accounts is also simpler at tax time. When all business income and expenses flow through one account, your Schedule C practically writes itself. When business and personal transactions are mixed together in one checking account, you (or your accountant, at $200-$500 per hour) will spend hours untangling them every April.
Step 5: Write an operating agreement (even if you're the only member)
An operating agreement is an internal document that outlines how your LLC operates: who owns what percentage, how profits are distributed, what happens if a member leaves, and how decisions are made. Most states don't require you to file it with any government agency, but you should have one.
For single-member LLCs, the operating agreement establishes that the LLC is a separate entity from you (reinforcing the liability protection) and makes banking, loan applications, and potential future partnerships simpler. Free templates are available from LLC University and multiple state bar associations. You don't need a lawyer for a basic operating agreement unless you have multiple members with complex profit-sharing arrangements.
Step 6: Handle licenses, permits, and ongoing compliance
Your LLC formation doesn't automatically give you permission to operate your specific type of business. Depending on your industry and location, you may need state business licenses, local business permits, professional licenses (for fields like accounting, real estate, or healthcare), and sales tax permits (if you sell taxable goods).
The ongoing compliance requirements vary by state but typically include filing an annual report (fees range from $0 to $300; the average is $91), maintaining a registered agent (you can serve as your own in most states, or hire a service for $100-$300 per year), and paying any applicable state franchise taxes. If you fail to file your annual report or pay your fees, the state will dissolve your LLC, and you'll lose your liability protection until you reinstate it (which costs additional fees and penalties).
A registered agent is a person or service designated to receive legal documents (lawsuits, government notices, tax correspondence) on behalf of your LLC. You can be your own registered agent in most states if you have a physical address (not a P.O. box) and are available during business hours. The disadvantage is that your home address becomes public record. A commercial registered agent service costs $100-$300 per year and keeps your personal address private, which is worth considering if you run a home-based business.
California's $800 annual franchise tax is the most punitive for small businesses (though LLCs formed in 2024 or later get the first year waived). New York requires LLCs to publish a legal notice in newspapers for six consecutive weeks, costing $500-$1,200 depending on the county. These are outlier costs; in most states, maintaining an LLC costs $50-$200 per year.
The formation services trap (and when they're actually worth it)
ZenBusiness, LegalZoom, Northwest, and dozens of other services will form your LLC for you, charging anywhere from $0 (plus state fees) to $300+ for premium packages. They handle the paperwork, provide registered agent service, and offer add-ons like operating agreement templates, EIN filing, and compliance monitoring.
Here's the honest assessment: if your state has a straightforward online filing system (most do), you can do this yourself in 30 minutes and save $100-$300. The state filing form is not complicated. The EIN application is free from the IRS. Operating agreement templates are free online. The services are selling convenience, not expertise.
The exception: if your state has a complex filing process (New York's publication requirement, for example), if you have multiple members with different ownership percentages, or if you simply value your time at more than $100 per hour and would rather pay someone to handle the logistics, a formation service makes sense. Northwest ($39 plus state fees) is the most affordable option that includes registered agent service. LegalZoom ($149 plus state fees) is the most recognized brand but charges more for essentially the same paperwork.
The honest assessment of whether you actually need one
If your business carries any risk of being sued (you work with clients, sell products, provide services, have a physical location), the answer is almost certainly yes. The liability protection alone justifies the cost. A single lawsuit without LLC protection can wipe out your personal savings.
If you're testing a business idea with minimal revenue and no client-facing risk (selling digital products anonymously, for example), a sole proprietorship is fine as a starting point. You can always form an LLC later. Many successful businesses started as sole proprietorships and converted once the revenue and risk justified the administrative cost.
The tax question is more nuanced than most guides admit. A single-member LLC is taxed identically to a sole proprietorship by default. Both file on Schedule C, both pay 15.3% self-employment tax on net income. The LLC doesn't save you money on taxes unless you elect S-Corp taxation, which only makes financial sense once your net income exceeds roughly $40,000-$50,000 per year (the threshold where the S-Corp salary-versus-distribution savings outweigh the additional payroll and accounting costs).
The bottom line: an LLC costs $100-$300 to form and $50-$200 per year to maintain in most states. It protects your personal assets from business liabilities. It takes 30 minutes to file online. If you earn business income of any kind, the math favors filing. The 5.5 million people who started businesses last year didn't all need fancy lawyers or expensive consultants. Most of them needed a state website, a filing fee, and half an hour.
One final note: 20% of small businesses fail within the first two years, and 45% fail within five years. Having an LLC doesn't prevent failure, but it prevents failure from destroying your personal financial life. If your business doesn't work out, you close the LLC, settle its debts with its assets, and walk away with your personal savings intact. If your business doesn't work out as a sole proprietor, every business debt follows you home. For $132 and 30 minutes, the LLC is the cheapest insurance policy you'll ever buy for a business. File it today. You can figure out the rest while you're already protected.
