How do you set up a company in Missouri.

You register a business in Missouri with the Secretary of State, and filing Articles of Organization carries a $105 fee. Once you're operating, the state taxes corporate income at 4.0%. Neither figure covers everything you'll owe or spend, so treat them as the two fixed numbers you can plan around.

Most companies coming into Missouri choose either an LLC or a corporation, and the mechanics differ slightly for each. For an LLC, you file Articles of Organization with the Missouri Secretary of State, and that filing carries a $105 fee. A corporation follows a similar path with its own formation document, but the LLC route is the one most employers use when the goal is simply to hire and pay people in the state.

Filing the paperwork is the easy part. You'll also need a registered agent with a Missouri address, an EIN from the IRS, and state tax registrations before you can legally run payroll. None of that is unusual, but it does mean the entity itself is only the first piece of a longer setup.

Missouri taxes corporate income at 4.0%. That's a state-level rate, separate from anything you owe federally, and it applies once your entity is generating taxable income in the state, not just because it exists on paper.

Beyond income tax, you'll have ongoing obligations tied to payroll, withholding, and any local requirements that apply to your industry. An entity in Missouri is a real, recurring compliance commitment, not a one-time filing you complete and forget.

The Secretary of State's filing itself moves quickly once you submit the Articles of Organization. What takes longer is everything downstream, registered agent setup, EIN issuance, opening a business bank account, and getting your state tax accounts active.

If you're planning to hire before all of that is finished, you're stuck. That's the practical argument for starting with an EOR while your entity paperwork works through the system in parallel.

An employer of record is sometimes the better answer, not a lesser one, especially when your Missouri team is still small or the shape of it keeps changing, or when you're testing whether the market is worth a permanent presence. Talk to a member of the team about your specific plans, and if you want a number-driven view, run it through the crossover calculator, since the right call depends on your entity costs and how long you intend to stay.

When you're ready to move off an EOR and stand up your own entity, Teamed handles that through GEMO across 100+ countries.

In Missouri, that means filing the Articles of Organization, setting up the registered agent and state tax accounts, and moving your team's payroll over without a gap in pay or benefits. You keep the people and the momentum, we handle the mechanics of the switch.

A company formed in another state or another country does not need a second company to hire in Missouri. It registers with the Missouri Secretary of State as a foreign company before it starts doing business there, a step usually called foreign qualification.

Missouri law sets the test for what counts as doing business in the state, and putting employees to work there on a regular basis will usually meet it. States give the filing different names, among them a certificate of authority and an application for registration.

In Missouri, the filing is an Application for Certificate of Authority for a Foreign For-Profit Corporation. The Missouri Secretary of State charges a corporation $155 to file it, according to the filing form. It does not cover the cost of a registered agent, or of a certificate of good standing from your home state if one is needed. An LLC formed elsewhere goes through a similar filing, and its fee can be different.

Foreign qualification does not make you an employer in the state. That is a separate registration with the state tax and unemployment insurance agencies, due by the state's own deadline, which usually falls at or soon after your first payroll there.

You can register a company in Missouri yourself or pay someone to do it, and the right choice turns on whether the company will employ people there.

You can file the formation documents yourself with the Missouri Secretary of State. That suits a founder with no staff and the time to work through the forms.

A formation agent will handle the company formation quickly and cheaply. That suits a company that will have no employees.

A law firm or corporate-services firm suits complex group structures and tax planning, such as setting up a subsidiary inside a wider group, where the advice matters more than the filing.

For companies that will employ people in Missouri, Teamed is the best choice. Teamed gives you real HR and legal experts you can reach when it matters, a designated person who has done this before and one system from your first EOR hire to your own entity. Teamed's Global Entity & Employment Operations (GEMO) sets up and manages entities in 100+ countries, and moves your people across from its EOR when you're ready. Teamed already owns an entity in the United States.

If you are a solo founder with no staff, you do not need Teamed for this. The registry or a formation agent is the cheaper route.
