An LLC has one unavoidable cost, the state filing fee, and a handful of optional or recurring ones layered on top. Knowing which is which is how you avoid overpaying a formation service for things that are free.
To create an LLC you file articles of organization with your state and pay a filing fee. That fee ranges from around $35 to $500 depending on the state, with most falling between $50 and $200. It is a one-time charge. Estimate your state's total in the LLC cost calculator.
A few states have extra requirements. New York and Arizona require newspaper publication of your LLC formation, which can add a noticeable cost in expensive counties. Some states charge more for expedited processing. And if you form in one state but do business in another, you pay to register as a foreign LLC in the second state, doubling several of these fees. More on that in LLC pros and cons.
For a typical single-state LLC, budget the filing fee plus the recurring state fee, and optionally a registered agent. Many people get fully set up for under a few hundred dollars in year one, with a smaller recurring cost after that. The big variable is your state, not the paperwork.
You can file directly with your state and pay only the state fee, or hire a formation service that submits the paperwork for an added charge, sometimes advertised as free with a paid registered agent attached. The service buys convenience and a few reminders, not anything you cannot do yourself. If you are comfortable filling out a short state form, the direct route is cheapest. If you would rather not think about it, a service is a reasonable small cost.
The required cost is your state's filing fee, generally $35 to $500 with most between $50 and $200, paid once. On top of that you may have a recurring annual report or franchise fee and an optional registered agent service. Your state is the biggest factor.
Most states charge a recurring annual report or franchise fee to stay in good standing, ranging from nothing to several hundred dollars. California's minimum franchise tax is $800 a year. A registered agent service, if you use one, adds roughly $100 to $300 annually.
No. An EIN is free directly from the IRS, and you can write an operating agreement yourself from a template. Services that charge for these are charging for things you can get at no cost.
Usually not for a small business. If you form in one state but operate in another, you must register as a foreign LLC where you do business, which means paying fees and keeping a registered agent in both states. For most owners, the home state is cheapest.
