To add a DBA to an LLC in Ohio, file Form 534A (Name Registration) with the Ohio Secretary of State and pay the $39 filing fee. Ohio does not use the term “DBA” in its statutes; instead, you register either a trade name or a fictitious name under Ohio Revised Code Section 1329.01.1Ohio Legislative Service Commission. Ohio Revised Code Section 1329-01 The registration lasts five years and can be renewed.
Trade Name or Fictitious Name
Before you fill out anything, decide which of the two registrations you want. Form 534A handles both, and you check a box to tell the state which you’re filing.
A trade name gives you exclusive rights. The Secretary of State will approve it only if it’s distinguishable from every business name already on the state’s records, including corporations, LLCs, limited partnerships, and registered trademarks. Once you hold it, no one else can register something confusingly similar.
A fictitious name is the fallback. There’s no distinguishability requirement, so another business could register something identical or nearly identical to yours.2Ohio Secretary of State. Guide to Name Availability You’d use a fictitious name when the name you want is already taken, or when you don’t need exclusive rights.
If you’re building a brand under the new name, pay for the search work and go with a trade name. If you just need a secondary label for a product line or short-term venture, a fictitious name gets the compliance done with less risk of rejection.
Check the Name First
Search the Secretary of State’s business name database through Ohio Business Central before you file. The search is free and takes a few minutes, and it can spare you a $39 rejection if the name isn’t available.
Two naming rules catch LLC filers in particular. First, under Revised Code Section 1329.02, the state will reject any trade name that implies the registrant is a corporation.3Ohio Legislative Service Commission. Ohio Revised Code Section 1329-02 An LLC is not a corporation, so “Inc.” or “Corp.” in the name will get the application denied. Second, you should also leave “LLC” or “Limited Liability Company” off the registered name. The point of the registration is a brand identity separate from your legal entity, and repeating the entity designator defeats that.
What Form 534A Requires
Have this information ready before you open the form:
- The legal name of your LLC, exactly as it appears on your articles of organization.
- Your Ohio charter number — the identifier the Secretary of State assigned when the LLC was formed.
- The name you want to register, spelled and punctuated exactly as you want it recorded.
- A brief description of the business activity you’ll conduct under the new name.
- The signature of a member or manager with authority to bind the LLC.
Your business address on the form should match what the Secretary of State currently has on file for the LLC. Mismatches slow processing. You can download Form 534A from the Secretary of State’s website or complete the whole thing through Ohio Business Central.4Ohio Secretary of State. Filing Forms and Fee Schedule
How to File and What It Costs
The base filing fee is $39 whether you register a trade name or a fictitious name.4Ohio Secretary of State. Filing Forms and Fee Schedule You have three ways to submit.
Online
Ohio Business Central at OhioBusinessCentral.gov handles the filing electronically. You enter the information, pay by credit card or electronic check, and get a tracking number right away. This is the fastest and simplest route for most filers.
By Mail
Send the completed Form 534A with a check or money order payable to “Ohio Secretary of State” to P.O. Box 670, Columbus, OH 43216. Standard processing runs three to seven business days from receipt.5Ohio Secretary of State. Form 534A – Name Registration
Expedited
Three expedite tiers add to the $39 base fee. A $100 expedite returns the filing within two business days and works for online, mail (P.O. Box 1390, Columbus, OH 43216), or in-person submissions. A $200 tier gets it done in one business day but requires walk-in delivery to the Client Service Center at 180 Civic Center Dr., Columbus. A $300 tier turns filings around in four hours if received by 1:00 p.m., also walk-in only.5Ohio Secretary of State. Form 534A – Name Registration For anyone outside Columbus who needs speed, the $100 online option is the practical pick.
After the State Approves It
The Secretary of State issues a certificate of registration once the filing clears. Keep it accessible. Banks will ask for it before they let you open an account or deposit checks made out to the registered name, and you’ll want it when updating insurance policies and vendor agreements.
The registration is good for five years from the filing date. Renew during the six-month window before expiration using Form 523A and a $25 fee. Miss that window and the registration lapses; you’d have to file a fresh registration rather than a renewal.6Ohio Secretary of State. Form 523A – Renewal of Trade Name or Fictitious Name
Two things you don’t need to do: you don’t need a new EIN from the IRS. Adding a DBA doesn’t create a new entity, and your existing EIN carries over.7Internal Revenue Service. When to Get a New EIN You also don’t need a separate county-level filing. The state registration is the only one Ohio requires.
What Happens If You Skip It
Operating under an unregistered name in Ohio has real legal consequences. Under Revised Code Section 1329.10, your LLC cannot file or maintain a lawsuit in any Ohio court under a trade name or fictitious name until you’ve registered it.8Ohio Legislative Service Commission. Ohio Revised Code Section 1329-10 If a customer breaches a contract signed under your unregistered name, you can’t sue them until you fix the registration.
Ohio does allow retroactive compliance. Once you register, you can sue on contracts made before registration. But during the gap you’re exposed, and other parties can still sue you under the unregistered name with no such restriction.
Canceling or Transferring the Name
If you stop using the registered name, file Form 524A with a $25 fee to cancel it, either online or by mail.9Ohio Secretary of State. How to Dissolve or Cancel a Business Entity Ohio also allows you to transfer a registered name to another entity by filing a written assignment signed by the current owner, again for $25. The state then issues a new certificate to the assignee for the remainder of the original five-year term. This matters if you’re selling a business line that operates under a registered name.
State Registration Is Not a Trademark
Registering a name with the Ohio Secretary of State makes it distinguishable on the state’s records. It does not give you trademark rights. The protection stops at the Ohio border and doesn’t extend to logos or slogans. If your LLC sells nationally or online across states, a federal trademark through the United States Patent and Trademark Office is a separate step worth taking.10United States Patent and Trademark Office. How Trademarks and Trade Names Differ The Ohio filing is compliance; it isn’t brand protection.
