How to Check Business Name Availability in Florida Before You File

Why Business Name Availability Matters More Than You Think

Choosing a business name feels like the fun part of starting a company — but in Florida, it's also one of the most legally consequential steps you'll take. File a name that's already taken, too similar to an existing entity, or one that violates Florida's naming statutes, and you're looking at rejected filings, wasted fees, and potentially a rebranding headache down the road.

The good news? Checking business name availability in Florida is a straightforward process — if you know exactly where to look and what to look for. This guide walks you through everything CPAs, accountants, and new business owners need to know before filing with the Florida Division of Corporations.


Start With the Florida Division of Corporations (Sunbiz.org)

The official — and most important — place to check whether a business name is available in Florida is the Florida Division of Corporations website, commonly known as Sunbiz.org. This is the state's official business registry, and it's where all corporations, LLCs, limited partnerships, and other registered entities are recorded.

Here's how to run a basic name search:

  1. Go to Sunbiz.org
  2. Click on "Search Records" in the top navigation
  3. Select "Entity Name" from the search options
  4. Type in the business name you're considering
  5. Review the results for any active, inactive, or similarly named entities

One thing to pay attention to: the search isn't just about exact matches. Florida law under Section 607.0401, Florida Statutes (for corporations) and Section 605.0112 (for LLCs) prohibits names that are "distinguishable upon the records" from existing entities. That means a name that's only slightly different from an existing business may still be rejected.

For example, if "Sunshine Consulting LLC" is already registered, "Sunshine Consultants LLC" or "Sunshine Consulting Inc." could potentially be flagged as indistinguishable — depending on how the Division reviews it.


Understanding Florida's Business Name Rules

Beyond just checking availability, your chosen name has to comply with Florida's specific naming requirements. Here's what you need to know:

For LLCs:

For Corporations:

For Fictitious Names (DBAs):

Keep in mind that the Division of Corporations doesn't check for trademark conflicts — that's a separate step you'll want to handle on your own through the USPTO Trademark Electronic Search System (TESS).


How to Reserve a Business Name in Florida

Found a name that's available? Don't wait — someone else could file it before you do. Florida allows you to reserve a business name before you officially form your entity.

Here are the details:

This is especially useful if you're in the process of preparing your Articles of Incorporation or Articles of Organization and aren't ready to file the full formation documents yet. It locks in the name while you get everything else in order.


Don't Forget Federal and Trademark Considerations

Searching Sunbiz.org only tells you whether a name is available at the state level in Florida. It does not:

For CPAs advising clients on entity formation, this is a critical point to raise early in the engagement. A client who builds a brand around a name that's already trademarked nationally could face costly litigation — even if the Florida name search came back clean.

Here's a quick checklist before finalizing any business name:


What Happens If You File a Conflicting Name?

If you submit formation documents with a name that's already taken or doesn't meet Florida's requirements, the Division of Corporations will reject your filing and return it with a notice of deficiency. You'll need to correct the name and refile — but you won't automatically get a refund of your filing fees.

For LLCs, the standard filing fee is $125. For profit corporations, it's $70 for the Articles of Incorporation (plus a $35 registered agent fee). These aren't enormous amounts, but the real cost is the time delay — especially if you have client contracts, bank accounts, or licenses waiting on the entity formation.

This is why doing the name search before you file is so important. A few minutes of research upfront can save days or weeks of back-and-forth with the state.


Stay on Top of Your Florida Business Status Year-Round

Checking name availability is just the first step in a longer compliance journey. Once your business is formed, Florida requires annual reports filed between January 1 and May 1 each year — with a $138.75 fee for LLCs and $150 for profit corporations. Miss the May 1 deadline and you're hit with a $400 late fee, and continued non-compliance can lead to administrative dissolution.

Your business name and entity status can also change over time — mergers, name amendments, and dissolutions affect the registry constantly.
