How to File a DBA in Florida (2026)

What Is a DBA and Why You Need One in Florida

A DBA (Doing Business As), also called a fictitious name registration, is a legal filing that allows you to operate your business under a name different from your legal entity name. In Florida, both sole proprietors and LLCs must file a DBA with the Florida Division of Corporations if they operate under any name other than their registered legal name. The $50 filing fee registers your assumed name in state records, giving you legal rights to use that name and protecting it from other businesses in Florida.

You cannot legally conduct business under an assumed name in Florida without registering it. Operating without a required DBA exposes you to liability and prevents you from enforcing contracts under your business name. The DBA creates a public record showing you as the owner of that business name, which establishes your exclusive right to use it within Florida.

When Florida Requires You to File a DBA

You must file a DBA in Florida if you operate a sole proprietorship or LLC under a name that is not your legal entity name on file with the Department of State. According to Florida business formation requirements, both sole proprietorships and LLCs require DBA registration. If you are a sole proprietor operating under your personal name with no additional business name, you technically do not need a DBA—but you still need a local business license.

If you form an LLC named "Smith Consulting LLC" but want to market your services as "Smith's Tax Solutions," you must register that assumed name as a DBA. The same applies if you operate multiple business lines under different names from a single entity. Professional corporations and professional LLCs may use variations of their registered names without filing a DBA, provided they register the alternate name as a fictitious name under Fla. Stat. § 621.

File your DBA before you begin operating under the assumed name. Operating without a registered DBA violates Florida law and could result in fines or loss of legal rights to the name.

Where to File Your DBA in Florida

You file your DBA with the Florida Division of Corporations, which is part of the Florida Department of State. This is a state-level filing, not a county filing. The Division of Corporations maintains the official fictitious name registry for the entire state and is the only authority that can register your DBA.

You can file online through the Department of State's e-filing system at https://dos.fl.gov/sunbiz/start-business/efile/fl-llc/ or submit a paper application by mail or courier. Online filing is the fastest option and provides immediate confirmation.

DBA Filing Fee and Payment

The DBA filing fee in Florida is $50.00. This flat fee applies whether you are filing as a sole proprietor or an LLC. You pay this fee once at the time of initial registration. Payment methods vary by filing method—online filings typically accept credit cards, while mail submissions may require a check or money order.

The $50 fee covers the state-level registration only. Some counties may charge additional fees for local business tax receipts or occupational licenses, but these are separate from the DBA registration fee. Do not confuse the state DBA fee with local licensing costs.

Required Contents of a Florida DBA Filing

Your DBA application must include the following information to be accepted by the Florida Division of Corporations:

Your Legal Entity Information:

  • Your full legal name (if a sole proprietor) or your LLC's registered name
  • Your current mailing address
  • Your business address (if different from mailing address)

The Assumed Name:

  • The exact fictitious name or trade name you will use
  • The name must be clearly distinguishable from other registered names in Florida's records

Business Description:

  • A brief description of the business activities you will conduct under the assumed name

Ownership and Management:

  • Identification of the owner (sole proprietor) or managing member/manager (LLC)
  • For LLCs, confirmation that the assumed name is authorized by the operating agreement or member vote

Signature:

  • Your signature or electronic signature (for online filings)
  • Notarization is not required for DBA filings

The Department of State provides a standard form for fictitious name registration. You can access it through the SunBiz portal at https://dos.fl.gov/sunbiz/ or request it by phone at (850) 245-6052.

DBA Name Requirements and Availability Search

Your assumed name must meet Florida's naming standards. Under Fla. Stat. § 865.09, a fictitious name must be distinguishable from all other registered business names, DBAs, and entity names on file with the Department of State.

Names that are NOT considered distinguishable:

  • Names differing only by a suffix (Inc., LLC, Ltd.)
  • Names differing only by articles (a, an, the)
  • Names differing only by the symbols "&" or "and"
  • Names differing only by singular, plural, or possessive forms
  • Names differing only by punctuation or symbols

Before filing, search the state database at https://search.sunbiz.org/Inquiry/CorporationSearch/ByName to confirm your desired name is available. This search covers all registered entities, DBAs, and reserved names. If your name is not distinguishable, you can request written consent from the other entity holder and file that consent with your DBA application.

Avoid names that imply government affiliation or suggest purposes outside your actual business scope.

How to File Your DBA: Step-by-Step Process

Step 1: Search for Name Availability

Visit https://search.sunbiz.org/Inquiry/CorporationSearch/ByName and search your proposed DBA name. Confirm it is available or obtain written consent from any conflicting entity. This search is free and takes only minutes.

Step 2: Prepare Your Application

Gather your legal entity information, the assumed name, business description, and owner/manager details. If filing online, you can complete the form directly on the SunBiz portal. Have your Social Security number or EIN available.

Step 3: Submit Your Filing

  • Online: Visit https://dos.fl.gov/sunbiz/start-business/efile/fl-llc/, complete the form, and pay the $50 fee by credit card. This is the fastest method.
  • By Mail: Print the fictitious name registration form, complete it, sign it, and mail it with a check or money order to P.O. Box 6327, Tallahassee, FL 32314.
  • By Courier: Deliver the completed form and payment to 2661 Executive Center Circle, Tallahassee, FL 32301.

Step 4: Receive Confirmation

The Department of State will process your filing and issue a certificate of fictitious name registration. Online filings are typically processed within 1–2 business days. Mail filings may take 5–7 business days.

Step 5: Obtain Local Business License

After your DBA is registered, apply for a local business tax receipt or occupational license with your county or city. This is a separate requirement from the state DBA filing. Contact your county clerk's office for local requirements and fees.

DBA Renewal, Expiration, and Ongoing Compliance

Florida DBA registrations do not expire. Once filed, your fictitious name registration remains active indefinitely unless you voluntarily cancel it or fail to maintain your business license. However, you must maintain compliance with local requirements.

You must maintain compliance:

  • Renew your local business tax receipt or occupational license annually (requirements vary by county).
  • Update your DBA registration if you change your business address or ownership structure.
  • File an amendment if you want to add or remove an assumed name.

To amend or cancel a DBA, contact the Florida Division of Corporations at (850) 245-6052 or file an amendment through the SunBiz portal. There is typically a fee for amendments; check the current fee schedule on the Department of State website at https://dos.fl.gov/sunbiz/.

If you dissolve your business entity (sole proprietorship or LLC), your DBA registration automatically becomes inactive, but you should formally cancel it to avoid confusion.

DBA vs. LLC: When Each Makes Sense

A DBA and an LLC serve different purposes and are not mutually exclusive. Understanding the distinction is critical to protecting your business.

Use a DBA if you:

  • Operate as a sole proprietor and want to use a business name other than your personal name
  • Already have an LLC and want to operate under an additional assumed name
  • Want to test a business idea without forming a formal entity
  • Operate a side business under your personal name but want a professional business name

Use an LLC if you:

  • Want personal liability protection (an LLC shields your personal assets from business debts and lawsuits)
  • Plan to hire employees or seek business loans
  • Want to establish business credit separate from your personal credit
  • Operate a professional service (law, accounting, consulting) and need to comply with professional licensing rules
  • Expect significant business income and want tax flexibility

Key difference: A DBA is a naming registration only—it does not create a separate legal entity or provide liability protection. An LLC is a formal business structure that creates a separate legal entity with liability protection.

Example: You can file a DBA as a sole proprietor for $50, but you remain personally liable for all business debts. If you form an LLC and file a DBA under that LLC, you get both liability protection and the ability to use an assumed name. An LLC requires filing articles of organization with the Department of State (separate from the DBA) and costs more than a DBA alone.

If you operate a sole proprietorship and later want liability protection, you can convert to an LLC. Your existing DBA will remain valid under the new LLC structure, but you must ensure the LLC's registered name is distinguishable in state records.

Publication Requirements for Florida DBAs

Florida does not require you to publish your DBA in a newspaper or legal publication. Unlike some states, Florida has no mandatory publication requirement for fictitious name registrations. The state registration itself serves as public notice.

Your DBA is searchable in the state database at https://search.sunbiz.org/Inquiry/CorporationSearch/ByName, making it accessible to the public and other businesses. This online availability satisfies Florida's public notice requirement.

However, some counties or municipalities may require local publication as part of their business licensing process. Check with your county clerk or business licensing office to confirm local requirements in your jurisdiction.

Using Your DBA: Legal Rights and Restrictions

Once your DBA is registered with the Florida Division of Corporations, you have the legal right to use that name in business. You can open a business bank account, sign contracts, and advertise under the assumed name. The registration establishes your exclusive right to use that name within Florida's business records.

Important limitations:

  • A DBA does not grant you a trademark. If you want federal trademark protection, you must apply separately with the U.S. Patent and Trademark Office.
  • A DBA does not prevent others from using a similar name in other states or for different business purposes.
  • A DBA does not provide liability protection. You remain personally liable for business obligations unless you operate as an LLC or corporation.

If you plan to expand to other states, consider registering your DBA in those states as well, or apply for a federal trademark to protect your name nationally. A federal trademark provides nationwide protection and prevents others from using confusingly similar names across all states.

Common Mistakes to Avoid When Filing a DBA

Mistake 1: Confusing DBA with LLC formation. A DBA is not a business entity—it is a name registration. If you want liability protection, you must form an LLC or corporation separately. Many entrepreneurs mistakenly believe a DBA provides liability protection; it does not.

Mistake 2: Failing to search for name availability. Always search the state database before filing. If your name is not distinguishable, your application may be rejected, and you will lose your filing fee. This step takes only minutes and prevents costly delays.

Mistake 3: Neglecting local business licensing. Registering a DBA with the state does not satisfy local business licensing requirements. You must also obtain a business tax receipt from your county or city. These are two separate filings.

Mistake 4: Not updating your DBA when circumstances change. If you move your business, change ownership, or add a new assumed name, file an amendment promptly. Outdated information can complicate future transactions and legal proceedings.

Mistake 5: Assuming a DBA provides trademark protection. A state DBA registration does not prevent others from using the same name in other states or industries. If your name is valuable, apply for a federal trademark with the U.S. Patent and Trademark Office.

Mistake 6: Operating under an unregistered assumed name. Using a business name without filing a DBA may violate Florida law and could result in fines or loss of legal rights to the name. File before you begin operations.

Mistake 7: Filing your DBA in the wrong location. File only with the Florida Division of Corporations, not with your county clerk. County filings do not satisfy state requirements and leave your name unprotected.

Mistake 8: Submitting incomplete information. Provide accurate, complete information on your DBA application. Errors or omissions result in rejection and delays. Double-check all details before submitting.
