Every state has one official office where you check your business name and file your LLC. Pick your state and this takes you there.
It is a list of links, nothing more. Every US state, plus DC, has one official office where you file an LLC. In most states it is the Secretary of State. In a few it is a different department, and the tool tells you when that is the case so you do not get confused by the name.
Why there are no fees on this page. Filing fees change, sometimes every year, and a wrong number costs you a rejected filing. The official page always has the current fee. Read it there and write it in your checklist.
Filing service or do it yourself? Either way, check the name on the official site first. A filing service (the one we use is Northwest Registered Agent) files the same form for you, acts as your registered agent so your home address stays off the public record, and reminds you about the yearly filing.
