Serving Miami and all of South Florida

Two offices, one team, and clients from Homestead to Fort Lauderdale.

Florida entities are formed through the Florida Department of State, Division of Corporations, better known as Sunbiz, and that filing is only the first of several registrations a Miami business needs. Once the entity exists, most owners in Miami-Dade and Broward still have to request a FEIN, open a local business tax receipt with the county and the city, and check whether their trade needs a state license. Many of our clients are family-owned businesses or owners who arrived from Latin America and want to understand what each Florida filing actually means before they sign it.

Visits are by appointment. Most of the work can also be done remotely.

Frequently asked questions

Straight answers about this service. For anything else, call us or ask the assistant.

How do I register a business in Miami?

You choose the entity, check the name on Sunbiz and file articles of organization or incorporation with the Florida Department of State. After that come the FEIN, the county and city business tax receipts and any state license your trade requires. Overthink prepares each step with you, in the order the agencies expect.

Should I open an LLC or a corporation in Florida?

It depends on how many owners you have, how you plan to pay yourself and whether you expect outside investors. We walk you through the practical differences and the tax treatment of each option so you can choose with clear information; the decision is always yours.

What documents do I need to register a business in Florida?

A proposed name and one or two alternatives, the names and addresses of the owners, a Florida business address and a decision about who will act as registered agent. If you already have a lease or a partnership agreement, bring it too.

Is Sunbiz registration enough to start operating in Miami-Dade or Broward?

Not by itself. The Sunbiz record creates the entity, but operating in Miami-Dade or Broward usually also requires a FEIN, a county and city business tax receipt and, in regulated trades, a state license. We map those steps for you on the business licenses and permits side once the formation is done.

Can I open an LLC in Florida without a Social Security number?

Florida does not limit ownership of an LLC or corporation to residents, so the formation itself is usually the simpler part. The federal tax ID that follows has its own path for owners without a Social Security number, which we cover on the EIN number application page. We explain both parts in your first conversation.

How much does it cost to register a business in Florida?

It depends on the entity you choose, whether you need a registered agent service and which local licenses your activity requires after formation. The state and county charges are set by each agency and change over time. We lay out the complete list for your case in the first conversation, so nothing appears later by surprise.

How long does it take to register a business in Miami?

It depends on how quickly you settle the name and ownership details and on the processing pace at the Florida Department of State when you file. What we control is that the filing goes in complete and correct the first time. We tell you what to expect for your case when we review it together.

Do you register businesses in Spanish, and can it be done remotely?

Yes. Our consultants work in Spanish and English, by appointment at our offices in Palmetto Bay (Miami-Dade) and Sunrise (Broward), and most of the formation can be completed remotely with documents signed electronically. Contact Overthink to book a first conversation.
