Ohio business license: do you need one and how to get it

Do you need a business license in Ohio?

You’ll likely need a license to operate a business in Ohio, but the state doesn’t offer a general license that applies to all businesses. Your business could need a vendor's license to collect sales tax, a professional license to provide certain services, or a local permit to operate a particular type of business. The right license for you depends on what you sell, where you operate, and how your business is structured. You can get one through the OH Tax eServices site or directly through your county’s auditor.

What is an Ohio vendor's license?

An Ohio vendor's license allows your business to make taxable retail sales and collect the required sales tax. 

There are three primary license types: 

• Regular county vendor's license (Form ST-1): This $50 license is for businesses selling taxable goods or services from a fixed location in Ohio. You’ll typically need one county vendor’s license per physical business location.
• Transient vendor's license (Form ST-1T): This $50 license is valid state-wide for qualifying sellers who do not maintain a fixed place of business, instead operating out of temporary locations such as fairs, festivals, and flea markets. 
• Seller's use tax account (Form UT 1000): An out-of-state seller may need a seller’s use tax account to collect and remit Ohio sales tax. Registration is free. You’ll need this license if you are an out-of-state seller with substantial nexus — when you do enough business in Ohio to need a license. 

Businesses can apply through Ohio's tax registration website or through their local county auditor's office. Online applications for vendor's licenses can be processed immediately after the business establishes its required tax account.

Not every service is taxable, and some service providers have special rules or thresholds. For example, services like landscaping, lawn maintenance, and janitorial care are taxable after you reach $5,000 in annual sales from those services.

The Ohio Department of Taxation’s guide to taxable services can help you determine if your business needs a vendor's license.

How to get a business license in Ohio in 5 steps

The process for getting an Ohio business license depends on your business structure, sales, location, and industry. 

These are the five steps you’ll typically need to follow: 

1. Choose a business structure and register your business

Decide whether to operate as a sole proprietor, partnership, LLC, or corporation. If you form an LLC or corporation, file the appropriate formation documents with the Ohio Secretary of State. Filing articles of organization for a domestic Ohio LLC costs $99.

2. Get an employer identification number

An employer identification number (EIN) is a federal tax ID issued by the IRS. You may need one to hire employees, operate a partnership or corporation, or open a business bank account. Even when it isn’t legally required, an EIN can help keep your business and personal finances separate.

Apply for an EIN directly through the IRS. There is no application fee, so avoid third-party sites that charge for a service you can complete for free.

3. Apply for the appropriate vendor's license

If your business makes taxable sales, register through Ohio's tax website or apply through your county auditor.

Be prepared to provide information about your business including its legal name, address, ownership details, and business activity. You may also need your North American Industry Classification System (NAICS) code, which identifies your primary business activity. Make sure you choose the license that best fits your business activities. 

A successful online application will be processed immediately, allowing you to obtain the license without waiting for a mailed certificate. Keep a copy with your business records. If you opt to apply by mail, approval could take up to six weeks. 

4. Check city and county requirements

The city or county where your physical business is located may have additional requirements for local business licenses, zoning, building permits, signage, and home-occupation rules. Requirements can vary, even between neighboring communities.

You may also need to register for municipal income tax. Many Ohio municipalities impose income tax on business net profits, and the applicable filing and registration rules depend on the location and circumstances of your business.

5. Obtain any occupational licenses or permits

Certain types of businesses require additional credentials before they can legally begin operations. For example, you’ll need additional licenses or certifications if you’re a cosmetologist, barber, real estate professional, or contractor, among other professions.

If your business falls under one of these categories, you may need a state-issued professional license, a local contractor registration, a food-service license, or a different type of permit altogether. 

Confirm specific requirements with the agency that regulates your occupation before accepting customers or beginning work.

How much is a business license in Ohio?

Do you need a city or county business license in Ohio?

Ohio counties and municipalities may administer specific licenses, permits, and registrations for certain business activities.

Many cities require licenses or permits for particular businesses, such as contractors, vendors, and food-service operators. Depending on the activity, local requirements could also cover inspections, signage, zoning, or operating from a residential property.

Many Ohio cities also tax business net profits, and you may need to register your business and file returns with the municipality or an authorized tax administrator.

If you operate in Columbus, Cleveland, Cincinnati, or another Ohio city, contact your local income tax and licensing office to determine what applies to your address and business activity. If your business works across multiple municipalities, ask each city’s office how local taxes and permits should apply to each of your business locations.

Which Ohio occupations need a state license?

Like many states, Ohio regulates certain occupations to establish minimum qualifications and protect consumers. Licensing requirements vary by profession, and some trades are regulated locally rather than through a statewide occupational license.

These are some common examples of professions that require additional licensing: 

• Commercial electrical, HVAC, plumbing, hydronics, and refrigeration contractors: The Ohio Construction Industry Licensing Board (OCILB), within the Ohio Department of Commerce, licenses qualified contractors in these five specialty trades. Residential contractor requirements are generally handled by local building departments, which may have their own licensing or registration rules.
• Cosmetologists and barbers: The Ohio State Cosmetology and Barber Board regulates individuals and businesses providing services such as cosmetology, barbering, and certain related services. Business owners should check both individual practitioner credentials and applicable establishment requirements.
• Real estate professionals: The Ohio Department of Commerce's Division of Real Estate and Professional Licensing regulates real estate brokers, salespeople, appraisers, and other covered professions. If you work in these industries, you may need an individual license to practice in addition to holding a business license for your business. 
• Health care professionals: Ohio's relevant professional boards regulate occupations such as nursing, medicine, dentistry, pharmacy, and other licensed health services.

The state of Ohio maintains an occupational license lookup covering licenses issued by multiple agencies. You can use this tool to identify the appropriate regulatory board, then confirm the current requirements for operation directly.

What if I have a cleaning business in Ohio?

If you own an Ohio cleaning business, you’ll typically need a vendor's license once your taxable service sales reach $5,000 in a calendar year. Once you’ve reached that threshold, your business must register and collect sales tax on covered services. You should not need a separate state occupational license just to offer standard cleaning services, although local permits and other rules may apply.

What if I have a landscaping business in Ohio?

If you own a landscaping business in Ohio, you’ll need a vendor's license once you reach $5,000 in taxable service sales. If you apply pesticides as part of your service, you’ll also need a commercial pesticide applicator license from the Ohio Department of Agriculture.

Ohio tax registrations that come with starting a business

A vendor's license is only one part of successful business tax compliance. Depending on your operations, you may need several additional accounts, especially if you employ any workers.

• Employer withholding: Businesses that must withhold Ohio income tax from employees need to register with the Ohio Department of Taxation within 15 days after the withholding obligation begins.
• Unemployment insurance: If you employ any workers, determine whether your business is liable for Ohio unemployment taxes, then register with the Ohio Department of Job and Family Services when required.
• Commercial activity tax (CAT): As of tax year 2025 and later, Ohio's annual exclusion is $6 million in taxable gross receipts. If your company’s annual taxable gross receipts exceed this threshold, review the current CAT registration and filing rules.
• Municipal income tax: In certain Ohio cities, you may need to register and file municipal net profit tax returns.

These requirements are separate from the business license process. Check each agency's rules to determine when registration and filing obligations begin.

How a business license helps with financing and business credit

Lenders, landlords, and suppliers may ask you for proof of business registration, licensing, or tax identification before approving a financing or rental application. Keeping your business records organized can make it easier for you to establish business banking relationships and apply for financing.

A registered business with its own EIN, bank account, and supplier accounts also has a strong foundation for establishing business credit.

The bottom line

Ohio does not issue a general business license, but businesses making taxable sales may need a vendor's license, and regulated occupations and local rules can add other requirements. 

Start by identifying the licenses, permits, and tax registrations that apply to your business, then confirm the fees and application process with the responsible agencies.
