To register a DBA in Ohio, file a Name Registration (Form 534A) with the Ohio Secretary of State and pay a $39 fee.1Ohio Legislative Service Commission. Ohio Revised Code 1329.01 – Registration of Trade Name Definitions Ohio calls these filings “trade names” or “fictitious names” depending on whether the name is available for your exclusive use. Both go to the same office, cost the same, and stay valid for five years before renewal.
When You Have to Register
If you do business under any name other than your own legal name or your entity’s official name on file with the state, Ohio requires you to register that name. The rule reaches individuals, general partnerships, limited partnerships, LLCs, corporations, professional associations, and other organizations.1Ohio Legislative Service Commission. Ohio Revised Code 1329.01 – Registration of Trade Name Definitions
For a sole proprietor, the trigger is adding anything to your full legal name. “Jane Smith” needs no filing. “Jane Smith Consulting” does. For an LLC or corporation, the trigger is operating under any name different from the one in your charter documents.
Trade Name or Fictitious Name
Ohio distinguishes between the two, and the choice matters. A trade name is one you register for your exclusive use, and the Secretary of State will accept it only if it is distinguishable from every other name already on file.2Ohio Legislative Service Commission. Ohio Revised Code 1329.02 – Restrictions Against Filing Once registered, it is effectively reserved for you at the state level.
A fictitious name report is the fallback when the name you want isn’t available as a trade name, or when you don’t need exclusive rights. It puts your name on the public record and satisfies the disclosure requirement, but it doesn’t stop anyone else from using something similar. Same form, same fee.3Ohio Secretary of State. Business Filing Forms and Fee Schedule For most businesses, the trade name is the better pick: you get name protection at no extra cost or effort.
Check the Name Before You File
The Secretary of State will reject your application if the name fails any of a few tests. The name must be distinguishable from all other trade names, corporate names, LLC names, limited partnership names, and registered trademarks on the state’s records.2Ohio Legislative Service Commission. Ohio Revised Code 1329.02 – Restrictions Against Filing A tweak of a word or a different punctuation mark usually isn’t enough.
The name can’t imply a government connection you don’t actually have.2Ohio Legislative Service Commission. Ohio Revised Code 1329.02 – Restrictions Against Filing It can’t imply incorporation if your business isn’t incorporated, which means sole proprietors and general partnerships cannot use “Inc.,” “Corp.,” “LLC,” or “Company” in the name. And names containing “bank,” “banking,” or “trust” require prior approval from Ohio’s Superintendent of Financial Institutions before the Secretary of State will accept the filing.4Ohio Secretary of State.

Search the Secretary of State’s online business name database before you file. A few minutes there can save you $39 on an application that won’t go through.
Filing the Application
Your application needs the following:1Ohio Legislative Service Commission. Ohio Revised Code 1329.01 – Registration of Trade Name Definitions
- Your name and business address. Partnerships include at least one partner’s name and address. Entities list the entity type and the state of formation.
- The exact trade name or fictitious name you want to use.
- A brief description of the nature of the business.
- How long you’ve already been using the name in Ohio, if at all.
Sign the application yourself or have an authorized representative sign. You can download Form 534A as a PDF from the Secretary of State’s website, or file online through Ohio Business Central at OhioBusinessCentral.gov.3Ohio Secretary of State. Business Filing Forms and Fee Schedule The online portal is faster and confirms receipt immediately. Mail works but adds processing time.
The fee is $39.1Ohio Legislative Service Commission. Ohio Revised Code 1329.01 – Registration of Trade Name Definitions One name per application, so each additional name is another $39.
Once the registration comes back, bring a copy to your bank. Most banks require proof of your registered DBA before they’ll open a business account in that name or deposit checks made out to it.
Renewing Every Five Years
Ohio trade name and fictitious name registrations expire. Each one is valid for five years from the filing date, and you have to file a renewal within the six months before that term expires. The Secretary of State sends a reminder by mail or email to the last address on file, so keep your contact information current. Miss the window and the Secretary of State cancels the registration, freeing the name for someone else to claim.5Ohio Legislative Service Commission. Ohio Revised Code 1329.08 – Cancellation of Registration by Secretary of State
General partnerships have an additional trigger: they must renew whenever any partner named on the original filing leaves the partnership, regardless of where you are in the five-year cycle.6Ohio Legislative Service Commission. Ohio Revised Code 1329.04 – Effective Term of Registration or Report – Renewal Notice
Address Changes and Cancellation
If your business address changes, file a written update with the Secretary of State listing the registered name, the date of the original registration, and the new address.7Ohio Legislative Service Commission. Ohio Revised Code 1329.07 – Recording Changes of Business Address The update form is Form 524A and costs $25.3Ohio Secretary of State. Business Filing Forms and Fee Schedule
If you stop using the name or close the business, formally cancel the registration through Ohio Business Central or by submitting the appropriate form. Leaving it active ties up the name and can create confusion later.
What Happens If You Don’t Register
The biggest consequence is losing access to Ohio courts. Under ORC 1329.10, a business operating under an unregistered trade name or fictitious name cannot file or maintain a lawsuit in that name in any Ohio court until it complies with the registration requirement.8Ohio Legislative Service Commission. Ohio Revised Code 1329.10 – Injunction – Actions by and Against User of Trade Name or Fictitious Name If a customer owes you money or a vendor breaches a contract, you’re locked out until you file. Once you do register, you can pursue claims on contracts made before you were in compliance.
The Secretary of State can also refer the matter to the Ohio Attorney General, who may seek a court injunction ordering you to stop operating under the unregistered name until you file.8Ohio Legislative Service Commission. Ohio Revised Code 1329.10 – Injunction – Actions by and Against User of Trade Name or Fictitious Name For $39, it’s not a sensible risk to carry.
What a DBA Does Not Do
Registering a DBA is a state-level naming requirement. It doesn’t change your federal tax obligations and doesn’t require a new EIN; the IRS does not treat a name change as a trigger for a new number.9Internal Revenue Service. When to Get a New EIN Sole proprietors continue to report business income on Schedule C of Form 1040, same as before.10Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship)
A trade name registration also isn’t a trademark. It tells the Ohio public who stands behind the name, but a business in another state, or in a different industry, can use an identical name without infringing your registration. If the name is central to your brand, consider a federal trademark through the U.S. Patent and Trademark Office in addition to the Ohio filing.
