How to Start an LLC in Ohio (2025 Guide)

How to Form an LLC in Ohio in 5 Steps

In order to form your LLC in Ohio, you will need to complete the following steps:

1. Name your Ohio LLC
2. Choose a Statutory Agent
3. File the Articles of Organization
4. Create an LLC Operating Agreement
5. Obtain an EIN

Step 1: Name Your Ohio LLC

Before you get started, you will need to pick a suitable name for your Ohio LLC.

This will need to comply with all applicable Ohio naming requirements and be both succinct and memorable, as this will make it easily searchable by your potential clients.

1. Ohio LLC Naming Guidelines

• Your name must include the words” Limited liability company”, the word “limited”, or one of the following abbreviations: “LLC, L.L.C., ltd”. 
• Your name cannot include words that could imply that your LLC is affiliated with a state or federal agency (e.g., FBI, Treasury, State Department, etc.).
• Your name cannot include restricted words without prior approval (e.g., “bank” or “trust” requires approval from the OH Dept. of Commerce).
• Your name must be distinguishable from any other Ohio limited liability company, corporation, limited liability partnership, limited partnership, or trade name.

For more information, have a look at Section 1706.07 of the Ohio Revised Limited Liability Company Act: Naming of a Limited Liability Company.

2. Ohio Name Availability Search

To check whether your desired name is already taken by another business entity in Ohio, you can perform a name search on the State of Ohio’s website.

Keep in mind that if you’re not going to start your LLC right away, it might be a good idea to consider reserving your name. You can do this for up to 180 days by filing Form 534B – Name Reservation and paying the $39 filing fee. 

For more information, see our Ohio LLC Name Search guide. 

3. Finding the Right Domain

We recommend that you check online to see if your business name is available as a web domain. Even if you don’t plan to make a business website right away, this is an extremely important step as it will prevent others from acquiring it — potentially saving you both time and money in the long term.

Once you have verified your name is available, you may now select a professional service to complete the LLC formation process for you.

Step 2: Choose a Statutory Agent in Ohio

After you find the right name for your LLC, you will need to nominate an Ohio statutory agent. This is commonly known as a registered agent in states outside of Ohio. 

What is a statutory agent?

A statutory agent is an individual or business entity responsible for receiving important tax forms, legal documents, notice of lawsuits, and official government correspondence on behalf of your business. You can think of your statutory agent as your business’s primary point of contact with the state.

Who can be a statutory agent?

A statutory agent must be a statutory of Ohio or a foreign corporation authorized to conduct business in the state of Ohio. Most LLC owners choose to use a business attorney, act as their own registered agent, or use a registered agent service. You can choose to elect an individual within the company (e.g., yourself, etc.), use an attorney (not recommended due to the high cost), or go with a registered agent service.

Step 3: File Your Ohio LLC Articles of Organization

To register your LLC, you’ll need to file Form 610: Articles of Organization with the Ohio Secretary of State. You can do this online or via mail.

Before filing, you will need to make sure you have the information needed to complete your Certificate of Formation correctly. This includes: 

• The completed filing form cover letter, which includes your name, address, phone number, and email address
• The type of service being requested; you can choose between a regular service, three expedited service options, and preclearance filing (i..e, filing to be processed at a later date.). 
• The name of your LLC, as well as its effective date and time
• Your LLC’s purpose (this part is optional)
• The names of all authorized LLC members, managers, or representatives
• Your statutory agent’s name and mailing address
• The completed Acceptance of Appointment section. 
• The signatures of all LLC incorporators

Step 4: Create an Ohio LLC Operating Agreement

An operating agreement is not required in Ohio, but it’s a good practice to have one.

What is an operating agreement? An operating agreement is a legal document outlining the ownership and operating procedures of an LLC.

Why are operating agreements important? A comprehensive operating agreement ensures that all business owners are on the same page and reduces the risk of future conflict.

Step 5: Get an Ohio LLC EIN

You can get an Employer Identification Number (EIN) from the IRS for free. It is used to identify a business entity and keep track of a business’s tax reporting. It is essentially a Social Security number (SSN) for the company.

Why do I need an EIN? An EIN number is required for the following:

• To open a business bank account for the company
• For federal and state tax purposes
• To hire employees for the company

Where do I get an EIN? An EIN is obtained from the IRS (free of charge) by the business owner after forming the company. This can be done online or by mail.

Important Next Steps to Protect Your Ohio LLC

After you’ve formed your LLC, you’ll need to complete several key steps in order to:

• Separate your personal and business assets
• Stay compliant with state and federal laws

1. Get a Business Bank Account and Credit Card

Getting a dedicated business bank account is an essential part of operating legitimately as it keeps your personal and business assets separate, and therefore helps shield your personal limited liability. 

Skipping this step can often lead to:

• Courts determining that you haven’t been treating your LLC as a separate entity
• Your “corporate veil” being pierced, meaning that you will no longer benefit from limited liability in law.

You can also choose to acquire a corporate credit card if you’re interested in building your credit and potentially raising capital down the line. 

2. Check If You Need an Ohio Business License

Ohio does not require LLCs to hold a “general” business license in order to operate. 

Even so, you should know that business licensing is regulated at a local, state, and federal level, so your licensing needs will ultimately depend on your exact location and industry:

• Local Licenses: You’ll need to check with your city or county clerk’s office to identify any local licensing requirements, such as zoning permits or health department approvals you’ll need. 
• State-Level Licenses: You can use the Ohio License Look-Up tool to see what professional or occupational licenses may be required for your business based on its services or industry.
• Federal Licenses: While most Ohio LLCs will not be subject to federal regulation, those involved in heavily regulated industries (such as agriculture, alcohol, and firearms) will. You can have a look at this Small Business Administration article for the relevant federal agency you’ll need to contact.

A few questions to ask yourself when deciding whether you need a license include:

• Will you sell, lease, or rent taxable goods or services? If so, you’ll need to obtain a vendor license (also known as a seller’s permit) from the Ohio Department of Taxation. You can find more information on this on our Ohio Sales Tax guide. 
• Will you work as a licensed professional? If your LLC will focus on regulated fields — such as medicine, law, insurance, or real estate — you’ll need to ensure that you or a member of your LLC is appropriately licensed.
• Will your LLC’s activities negatively impact the environment? If so, you might need to obtain a business license or permit from the Ohio Environmental Protection Agency.

3. Understand Your Ohio LLC Tax Obligations

Ohio LLCs are not all taxed in the same way; this is because LLCs are taxed as pass-through entities by default, meaning that they are largely taxed similarly to sole proprietors — the business gets paid, the profits pass to you as the owner, and you get taxed. There is no “corporate” tax involved. 

This means that:

On a Federal Level

You’ll need to submit personal income tax returns using either Form 1040 (for single member LLCs) or Form 1065 (for multi-member LLCs). If you have employees, you will also be subject to federal income tax withholding. 

On a State Level

Your LLC may be required to pay Commercial Activity Tax (CAT) on gross receipts, state sales tax on taxable goods or services, and Financial Institutions Tax (FIT) if your business holds significant financial assets.

Keep in mind that if your LLC will have employees, you will also need to register for Ohio employer withholding.

On a Local Level

Your LLC may be required to pay property taxes, local sales and use taxes, or other location-based fees depending on where your business operates and what it does. These may include lodging taxes, transit authority taxes, and other supplemental local taxes imposed by your city or county.

For more information on the Ohio-specific LLC tax obligations that may apply to you, we recommend having a look at our in-depth Ohio LLC Taxes guide. Alternatively, you can schedule a free online consultation with 1800-Accountant for all your tax-related questions. 

4. Get Business Insurance for Your LLC in Ohio

Even though an LLC offers limited liability, you’ll still likely need to purchase some form of business insurance to protect your LLC’s assets. 

This is because an LLC’s default limited liability protects your personal assets, not the business’s. Some of the most common types of business insurance include:

• General Liability Insurance: This is a broad insurance policy that protects your business from lawsuits. Most small businesses end up getting general liability insurance.
• Professional Liability Insurance: This is a business insurance policy for professional service providers (consultants, accountants, etc.) that covers against claims of malpractice and other business errors.
• Workers’ Compensation Insurance: This type of insurance covers medical expenses and lost wages if an employee is injured while performing job duties, and is required for any Ohio business with one or more employees.

5. Learn How to Properly Sign Your LLC’s Legal Documents

Improperly signing a document as yourself and not as a representative of the business can leave you open to personal liability. 

When signing legal documents on behalf of your company, you we recommend following this formula to avoid any problems:

• Formal name of your business
• Your signature
• Your name
• Your position in the business as its authorized representative

It’s important to be consistent and sign all official documents using this format; this will help protect your personal assets by clearly showing that the agreement is with the LLC, not you as an individual.
