How to Use Ohio Business Central to File Your LLC or Corporation

Ohio Business Central is the online filing portal for the Ohio Secretary of State (Ohio SOS). If you are forming a limited liability company (LLC) or a for-profit corporation in Ohio, this is where you submit your formation documents. This guide walks through the filing from start to finish, with the fees and rules you need before you click submit.

Disclaimer: This article is informational only. It is not legal or tax advice. Entity choice, ownership structure, and tax treatment depend on your situation. Talk with an attorney or a CPA before you file, especially if you have partners, outside investors, or operations in more than one state.

What You Need Before You Start

Gather these items before you open the portal. A filing that stalls on missing information costs you days, and the Secretary of State will not process articles without the agent paperwork.

• A business name that meets Ohio's naming rules (see Step 2)
• A statutory agent, Ohio's term for a registered agent, who meets the residency or business address rules (see Step 3)
• The principal business address and the names and addresses the form requires
• The written statutory agent appointment and the agent's signed acceptance, on the prescribed form
• A free Ohio Business Central account
• A payment method. The portal accepts card and other online payment methods listed on the site.
• The correct form: Form 610 (Articles of Organization for a Domestic Limited Liability Company) for an LLC, or Form 532A (Initial Articles of Incorporation for a Domestic For-Profit Corporation) for a corporation

Step-by-Step: Filing Your Ohio LLC or Corporation

Step 1: Choose Your Entity Type

Decide whether you are forming an LLC or a for-profit corporation before you open the portal. The filing fee is the same, $99, but each entity uses a different form and carries different governance and tax rules. Ohio LLCs and for-profit corporations do not file an annual or biennial report, so the formation filing is not followed by a yearly state report. Ohio also has no franchise tax and no LLC annual tax, but businesses above the gross receipts threshold owe the Commercial Activity Tax (see the section on taxes below). Entity choice is a decision to make with a professional, not with a form.

Step 2: Search and Reserve Your Name

Start with a search on the Ohio SOS Business Search at https://businesssearch.ohiosos.gov/. Under Ohio law, your name must be distinguishable from the name of any other domestic or foreign LLC, corporation, limited liability partnership, limited partnership, or registered trade name on the Secretary of State's records, unless the prior holder consents in writing. A near match can be rejected even if the exact words differ, so search variations and abbreviations.

For an LLC, the name must include the words limited liability company or one of these abbreviations: L.L.C., LLC, limited, ltd., or ltd. For a corporation, confirm the naming rules on the Ohio SOS site before you file, because this guide does not cover them.

If you need time to finish the paperwork, you can reserve the name for 180 days for $39. Reservations are filed through the same portal, so you can do this from your Ohio Business Central account.

Step 3: Appoint Your Statutory Agent

Every Ohio LLC must appoint and continuously maintain a statutory agent. The agent must be either a natural person who is an Ohio resident, or an entity such as a corporation, LLC, or partnership with a business address in Ohio. The address you list must be:

• For an individual, the street address of the agent's primary Ohio residence
• For an entity, the agent's usual place of business in Ohio

A post office box does not qualify, even one with an associated street address. The Secretary of State will not accept articles of organization unless they come with a written appointment signed for the company and a written acceptance signed by the agent on the prescribed form. Make sure the agent has signed before you submit. If the agent later moves, changes, or resigns, the change costs $25, and a resignation takes effect 30 days after it is filed.

Step 4: Create Your Ohio Business Central Account

Go to https://www.ohiobusinesscentral.gov/ and set up a free account. Use an email address you will still check in five years, because filing confirmations and renewal notices go to the account holder. Ohio's Secretary of State handles nearly all business filings online, so the account is the same tool you will use for later filings such as statutory agent changes and business certificates.

Step 5: Start the Filing and Enter Your Information

Select the filing that matches your entity: Form 610 for an LLC or Form 532A for a corporation. Enter the business name exactly as you searched it, the principal office address, and the statutory agent information. The portal walks you through each field. Read the entries back before you move on, because a typo in the agent's address or the entity name is the most common reason a filing is delayed.

Step 6: Decide on Expedited Processing

Regular processing typically takes 3 to 7 business days from the date the Secretary of State receives the filing. Filing online through Ohio Business Central is the fastest standard route.

The Secretary of State also offers paid expedited processing. Older state forms list $100 for processing within 2 business days, with higher tiers for walk-in filings. Those older figures may not reflect current fees or timelines. Check Ohio Business Central for the current expedite fee and processing time before you choose an option. Expedite only if a deadline, such as a lease, a bank account, or a contract signing, needs the paperwork sooner.

Step 7: Pay and Submit

Review the full summary page once more. Then pay the filing fee, plus any expedite fee you selected, with a card or another online payment method listed on the portal. Save the confirmation page and the confirmation email. Those records show the date and amount you submitted.

Step 8: Confirm Your Filing Appears

After processing, search for your business on Business Search at https://businesssearch.ohiosos.gov/. Confirm the entity name, entity type, and statutory agent match what you filed. If something is wrong, contact the Secretary of State promptly, because the agent and name details carry through every later filing.

After the Filing: Taxes, Licenses, and Local Rules

Forming the entity does not complete your setup. Several obligations come after the filing, and they are handled through different agencies.

• No state general business license. Ohio issues no single general state business license. Some professions and industries need a license from a specific state board or agency, so check with the agency that regulates your work. Counties issue no business license.
• Commercial Activity Tax (CAT). Ohio has no franchise tax and no LLC annual tax. Instead, businesses pay the CAT, a gross receipts tax of 0.26% on Ohio taxable gross receipts. For tax year 2025 and later, only businesses with more than $6 million of Ohio taxable gross receipts owe the CAT or must register. CAT filing frequency depends on your receipts. Taxes are filed separately from the formation filing, through Ohio Business Gateway. Ohio does not levy a corporate income tax. Check with the Ohio Department of Taxation at https://tax.ohio.gov/ to confirm whether your gross receipts put you above the exclusion.
• Vendor's license. If you sell taxable goods or services in Ohio, you need a vendor's license before your first taxable sale. The county auditor issues the sales tax vendor's license under a state statute. As of April 9, 2025, the application fee for a county vendor's license is $50, and you can apply through Ohio Business Gateway or the county auditor. The state sales tax rate is 5.75%, plus county and transit authority rates that vary by county.
• Trade names. If you do business under a name other than your legal entity name, register it with the Secretary of State for $39. Trade names are not registered with the county.
• Workers' compensation. If you have employees, you purchase workers' compensation coverage from the state fund run by the Ohio Bureau of Workers' Compensation (BWC). Confirm your employer obligations with BWC before you hire.
• City and village income tax. Cities and villages tax business net profit under their own rates. Check with your municipality to confirm the rate and filing requirements that apply to your address and activity.

Common Mistakes to Avoid

• Using a post office box as the statutory agent address. A PO box does not qualify, even with a street address attached.
• Submitting without the signed agent acceptance. The Secretary of State will not accept articles without the written appointment and the agent's signed acceptance.
• Skipping the name search. A similar name on the records can cause rejection, even if the words are not identical.
• Leaving off the LLC designator. An LLC name must include limited liability company or an approved abbreviation.
• Looking for an annual report. Ohio LLCs and for-profit corporations file none. Your recurring obligations are tax filings, such as CAT returns if you are above the threshold, not a yearly state report.
• Registering a trade name with the county. Trade names are filed with the Secretary of State.
• Paying for expedite without checking the current timeline. Older figures may not match what the portal shows today.

Expected Results

A complete, accurate filing submitted online will typically move through regular processing in about 3 to 7 business days. Expedited processing may shorten that window, depending on the tier you choose and the current rules on the portal. Processing times are set by the Secretary of State, so confirm them on Ohio Business Central before you plan around a date. After processing, you should be able to find your entity on Business Search, which is the easiest way to check that the filed information posted correctly.

Next Steps and Where to Get Help

Once your entity appears on record, work through the post-filing list above: confirm the Commercial Activity Tax position, obtain any vendor's license you need, register any trade name, and check workers' compensation and local tax obligations.
