How to Start an Online Business in Ohio: Vendor's License, Sales Tax and Nexus

Licensing for an Ohio ecommerce business is simpler than most people expect. Ohio does not issue a general state business license, and counties do not issue one either. What you do need is a vendor's license before your first taxable sale, a sales tax setup that charges the right rate to the right buyers, and a clear answer to whether sales to customers in other states create an Ohio tax obligation. This guide walks through those steps in order, using the fees and thresholds that apply as of October 2026.

Informational content, not legal or tax advice. This article explains how Ohio's rules generally work. It is not legal, tax or accounting advice, and your situation may differ. Confirm every figure with the agency named before you act. Talk with a qualified attorney or CPA before you form your entity or file taxes, especially if you sell digital products, ship to many states, or expect to approach the Commercial Activity Tax threshold.

What You Need Before You Start

Gather these items before you open any form. Incomplete applications slow down filings, and several of these items feed into later steps.

• A business name that meets Ohio rules. An LLC name must include “limited liability company” or an accepted abbreviation such as “LLC,” “L.L.C.,” “limited,” “ltd.” or “ltd”.
• An Ohio registered agent. Ohio calls this a statutory agent. It must be an Ohio resident or an entity with an Ohio business address, and it needs a street address, not a post office box.
• Your street address. Your home can serve as your place of business for the vendor's license.
• A federal Employer Identification Number (EIN) from the IRS.
• Access to Ohio Business Central for Secretary of State filings and to the Ohio Business Gateway or your county auditor's office for tax registration.
• A list of everything you plan to sell, including physical goods, digital downloads, subscriptions and services. This list decides what is taxable.
• Sales records by buyer location, if you already sell. You will need them to test the nexus thresholds in Step 7.
• Payment for fees: $99 for articles of organization, $39 for a trade name or name reservation, and $50 for the vendor's license.

Step 1: Confirm Which Licenses You Actually Need

An Ohio ecommerce business generally needs no general state business license. Ohio has no statewide general contractor license, and counties issue no business license. The Ohio Department of Taxation states that the licenses and permits a business needs depend on the type of business and come from state agencies, the county or the city. For most online sellers, the one near-universal registration is the vendor's license covered in Step 4.

Before you launch, check whether your product category needs a separate permit. Some regulated categories, such as food, alcohol or certain health products, have their own requirements. Confirm those with the agency that oversees the product.

Step 2: Form Your Entity and Secure Your Name

If you form an LLC, file Articles of Organization for a Domestic Limited Liability Company (Form 610) through Ohio Business Central at ohiobusinesscentral.gov. The filing fee is $99. Regular service takes 3 to 7 business days from receipt, and online filing is the fastest standard route. If you need speed, Expedite Service 1 costs $100 above the filing fee and is processed within 2 business days. Expedite Service 2 costs $200 and is processed within 1 business day.

Search the name before you file at businesssearch.ohiosos.gov. The name must be distinguishable from any other registered LLC, corporation, limited liability partnership, limited partnership or trade name on Secretary of State records. If you need time to finish paperwork, you can reserve a name for 180 days for $39.

If you plan to sell under a brand that differs from your legal name, register a trade name (Form 534A) for $39. Trade names are registered with the Ohio Secretary of State, not your county. Renewal costs $25 every five years, and an update costs $25. Forms are listed at ohiosos.gov business filing forms.

One point that surprises new LLC owners: Ohio LLCs file no annual or biennial report. You still must keep your registered agent current.

Step 3: Appoint a Registered Agent

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. You can act as your own agent if you are an Ohio resident with a primary Ohio residence. A business can serve as agent if it has a usual place of business in Ohio. Either way, the address must be a street address.

Plan for continuity. An agent's resignation takes effect 30 days after it is filed, and changing an agent, an agent's address or filing a resignation costs $25.

Step 4: Get Your Vendor's License Before Your First Taxable Sale

The vendor's license is the registration that lets you collect sales tax. It costs $50 per fixed place of business and is issued through the county auditor under Ohio Revised Code 5739.17. The fee went up from $25 to $50 as of April 9, 2025, under House Bill 366. You must hold the license before you make taxable sales, so apply before you open your store.

Your home counts as a fixed place of business. An online seller working from home generally needs one license. If you later rent a warehouse or open another fixed location, confirm with your county auditor whether you need another. Apply through the Ohio Business Gateway or your county auditor, and find current instructions at the Department of Taxation's vendor licensing page.

Out-of-state sellers that register only for a seller's use tax account pay no fee. That route matters if you meet the nexus tests in Step 7.

Step 5: Sort Your Products Into Taxable and Non-Taxable

List each product line before you set prices. Physical goods you sell to customers are generally taxable. Digital products and services are less clear. Ohio guidance on digital products and services can make them taxable, so ask the Department of Taxation about each product type. Do not assume a download is exempt because nothing ships. Save the written answers in your records.

If you buy inventory to resell, ask the Department of Taxation how to document those purchases with an exemption certificate before you buy. Keeping the paperwork in order from the start is far easier than reconstructing it later.

Step 6: Charge the Rate for Where the Buyer Receives the Goods

Ohio sales tax is based on where the buyer receives the goods. The customer's delivery address controls the rate, not your home or warehouse address. The state rate is 5.75%. Counties and transit authorities add permissive rates that vary by county, so combined rates differ across Ohio. Your checkout system or tax software should apply the rate for the exact delivery address. Spot-check a few rates against the Department of Taxation at tax.ohio.gov.

This guide covers Ohio tax only. Orders shipped to other states follow those states' rules, which can differ. Talk with a CPA about multistate filings before you expand your shipping map.

Step 7: Test Your Nexus If You Sell Outside Ohio

Nexus is the connection that obligates a seller to register and collect tax. Ohio uses economic tests for out-of-state sellers. You have substantial nexus with Ohio if either of the following is true in the current or preceding calendar year (ORC 5741.01(I)(2)(g) and (h)):

• Your gross receipts are above $100,000. Ask the Department of Taxation which receipts count toward this figure for your sales mix.
• You complete 200 or more separate transactions.

If you cross either line, you must register and collect Ohio sales and use tax. The transaction test catches many small orders, so a modest revenue figure can still trigger it. Tag each order with its ship-to state and calendar year, and recheck both tests every year. Confirm the timing of your registration with the Department of Taxation.

Step 8: Understand the Marketplace Facilitator Rules

If you sell through Amazon, Etsy or a similar marketplace, Ohio treats the marketplace facilitator as the seller for the sales it facilitates (ORC 5741.01). A marketplace seller generally does not collect tax on those sales, but you still report them. Keep marketplace sales reports alongside your own records. Sales you make through your own website remain your responsibility, and you should ask the Department of Taxation whether marketplace sales count toward your own nexus totals.

Step 9: Check Whether the Commercial Activity Tax Applies

Ohio has no corporate income tax and no franchise or LLC annual tax. Instead, businesses pay the Commercial Activity Tax (CAT), a gross receipts tax of 0.26% (.0026) 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. The threshold was $3 million in 2024 and $150,000 before 2024, so older articles may show outdated numbers. CAT returns are filed quarterly. Most new online sellers fall under the exclusion, but check with the Department of Taxation if your receipts approach $6 million.

Step 10: Cover the Remaining Obligations

Cities and villages tax business net profit under their own rates, and those rates are separate from state tax. Once you know your profit, check with your city's income tax office. If you hire employees, buy workers' compensation coverage from the state fund through the Ohio Bureau of Workers' Compensation. Ohio taxes business income through your personal return, and rates have changed recently, so confirm the current figures with a CPA.

Common Mistakes to Avoid

• Making your first taxable sale before the vendor's license is in hand. Apply first, then open your checkout to taxable items.
• Assuming your home address cannot be a place of business. It can, and it is the most common setup for an online seller.
• Listing a post office box as the registered agent address. A box does not qualify, even with an associated street address.
• Charging only the 5.75% state rate. County and transit rates vary, and the delivery address controls which rate applies.
• Treating digital products as tax-free without confirmation. Ask the Department of Taxation about each product type.
• Ignoring the 200-transaction test because revenue is low. Many small orders can create nexus on their own.
• Assuming marketplace sales need no reporting. The facilitator generally collects, but you still report those sales.
• Filing a trade name with the county. Trade names are registered with the Ohio Secretary of State.
• Expecting an annual LLC report. Ohio LLCs file none, but a current registered agent is still required.
• Relying on an older CAT threshold. The exclusion is $6 million for 2025 and later.

Practical Tips

• Run the name search before you pay for a reservation or a filing.
• Open a separate business bank account so sales tax collected is easy to trace.
• Keep a simple tax log with ship-to state, county, transaction count and gross receipts for each year.
• Put your vendor's license renewal and nexus recheck dates on a calendar.
• Get written answers from the Department of Taxation on any product you are unsure about, and keep them in your files.

What Results to Expect

Once you complete these steps, you should generally have a formed entity, a registered agent on file, a vendor's license for your home location, a documented list of taxable and non-taxable products, and a checkout that applies the rate for each delivery address. Processing times can vary, and agencies may ask for more information, so build extra time into your launch date. Your long-term tax position depends on your product mix, sales volume and shipping footprint, so treat this framework as a starting point rather than a guarantee that every filing is complete.

When to Talk to a Professional

An attorney can help you choose between an LLC and other structures, draft operating agreements and review vendor contracts. A CPA can help with multistate sales tax, digital product questions, the CAT and your personal income tax on business profit. The Ohio Small Business Development Centers network at clients.ohiosbdc.ohio.gov also connects new owners with advisors.
