How to Start an S Corp in Ohio: IRS Election, Ohio Tax Treatment and When It Pays

An S corp in Ohio is not a separate type of company you form with the Ohio Secretary of State. It is a federal tax election. You first form an Ohio corporation or LLC with the Ohio Secretary of State, then file IRS Form 2553 to ask the IRS to treat that entity as an S corporation for federal income tax. Ohio has no separate state S election. Ohio taxes the owners on the business income that passes through to them, and the state tax result is largely the same whether or not you make the federal election.

This guide covers the sequence of steps, the Ohio taxes that apply either way, and the situations where the election is worth the extra payroll and paperwork. This article is informational content, not legal or tax advice. Entity choice, reasonable owner pay, and city tax questions depend on your specific facts. Talk with an Ohio business attorney and a CPA before you file the election.

Ohio LLC vs. S Corp: What the Election Actually Changes

Most people searching for an Ohio S corp are really choosing between two paths. The table below shows what changes and what does not.

Item	Ohio LLC, no S election	Ohio LLC or corporation with S election
Formation filing	Articles of Organization (Form 610), $99	LLC: Form 610, $99. Corporation: Form 532A, $99
Annual report to Ohio	None required for LLCs	None required for for-profit corporations
Ohio income tax on business income	Taxed to owners as pass-through income	Same. Taxed to owners as pass-through income
Commercial Activity Tax (CAT)	0.26% of Ohio taxable gross receipts above the $6 million exclusion for 2025 and later	Unchanged. 0.26% above the $6 million exclusion
Federal tax treatment	Default LLC treatment (disregarded entity for one owner, partnership for more than one)	Taxed as an S corporation. Owners who work in the business must be on payroll
Payroll	Optional for owner draws	Required for owner-employees, with a reasonable salary

The Ohio column barely moves. The real difference is federal: how the owners get paid and how much of the profit is subject to federal payroll tax. That is the only reason to make the election, so the decision should start with that question, not with the Ohio paperwork.

Materials and Information You Need Before You File

• A decision on entity type: Ohio LLC or Ohio for-profit corporation
• A business name that meets Ohio rules (see Step 1)
• A statutory agent: an Ohio resident with an Ohio street address, or an entity with an Ohio business address. A post office box does not qualify
• A signed written appointment of the agent and a signed written acceptance by the agent, both required before the Secretary of State will accept the articles
• A $99 filing fee for the articles, paid through Ohio Business Central
• A federal Employer Identification Number (EIN) from the IRS
• A signed operating agreement (LLC) or bylaws and shareholder agreement (corporation)
• IRS Form 2553, signed by every shareholder or member
• A payroll plan that includes federal withholding, Ohio income tax withholding, and city withholding
• Workers' compensation coverage from the Ohio Bureau of Workers' Compensation state fund, if you will have employees

Step-by-Step: How to Start an S Corp in Ohio

1. Choose the entity and check the name. An Ohio LLC name must include "limited liability company" or one of the abbreviations "L.L.C.", "LLC", "limited", "ltd." or "ltd." The name must be distinguishable on the Secretary of State's records from any other registered entity or trade name. Search the name at Ohio Business Search. If you need time, you can reserve the name for 180 days for $39. For a corporation, confirm the corporate name rules on the Secretary of State site before you file.

2. Appoint a statutory agent. Ohio calls this a statutory agent. Every LLC must appoint one and keep one in place at all times. The address must be the street address of the agent's primary Ohio residence, or the agent's usual place of business in Ohio for an entity. The Secretary of State will not accept your articles without the written appointment and acceptance.

3. File the articles through Ohio Business Central. File Form 610 for an LLC or Form 532A for a corporation at Ohio Business Central. 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. Expedite Service 3 costs $300, requires in-person delivery, and is processed within 4 hours if received by 1:00 p.m., otherwise by noon the next business day. A preclearance review costs $50 and takes 1 to 2 business days. Expedited paper filings go to P.O. Box 1390, Columbus, OH 43216.

4. Get your EIN from the IRS. Apply for the EIN before you open a bank account, run payroll, or file Form 2553. Confirm the current application process at IRS.gov.

5. Adopt the governing documents. An LLC needs a signed operating agreement. A corporation needs bylaws and, if there is more than one owner, a shareholder agreement. Ohio does not require you to file these with the state, but they control how profits are split, how owners are paid, and what happens if an owner leaves. Your S corp election also depends on the entity having only one class of stock, so the agreement must not create different classes of ownership economics.

6. File IRS Form 2553. The election is filed with the IRS, not Ohio. Every shareholder, or every member of an LLC, must sign it. The IRS sets a deadline tied to the start of the tax year you want the election to take effect, so confirm the exact date on IRS.gov before you file. Keep the IRS acceptance notice in your permanent records. If you miss the deadline, relief may be available, but it is not automatic. Ask a CPA before relying on it.

7. Set up payroll before the first paycheck. Owners who work in the business must be paid a reasonable salary through payroll. Wages paid to employee-shareholders are subject to federal withholding, Ohio income tax withholding, and city withholding. Register for Ohio income tax withholding with the Ohio Department of Taxation. If you have employees, buy workers' compensation coverage from the Ohio Bureau of Workers' Compensation state fund.

8. Register for city income tax. Ohio cities and villages tax business net profit under their own rates, and that tax applies to an S corp's net profit as well. Ohio has no state general business license, so the city where you operate is the place to confirm your registration and filing schedule. Some businesses may be able to have the state administer the municipal net profit tax under Ohio Revised Code 718.80. Confirm whether that applies to you with the Ohio Department of Taxation and your city.

9. Get a vendor's license if you sell taxable goods or services. Ohio has no single general state business license, but the sales tax vendor's license is nearly universal for retailers. The county auditor issues the vendor's license, and the application fee is $50 as of April 9, 2025. Apply through the Ohio Business Gateway or the county auditor. The state sales tax rate is 5.75%, plus county and transit rates that vary by location.

10. Check whether the CAT applies. The Commercial Activity Tax is 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 returns are filed quarterly. The S election does not change this result.

11. Register a trade name if you do business under another name. A trade name or fictitious name is registered with the Ohio Secretary of State, not the county. The fee is $39.00.

How Ohio Taxes an S Corp's Income

Ohio does not levy a corporate income tax on S corporations in the way other states do. Instead, the owners pay Ohio personal income tax on the business income that passes through to them. For 2026, business income gets a $250,000 deduction and the remainder is taxed at a flat 3% under Ohio Revised Code 5747.01(A)(28) and 5747.02(A)(4). The state tax on your wages and other nonbusiness income follows the individual rate schedule, so confirm the current year's table at the Ohio Department of Taxation.

If you have nonresident individual owners, Ohio can require the entity to withhold tax at the 3% business rate on their share of income once it exceeds $1,000 under Ohio Revised Code 5747.41. The entity can avoid this by making the pass-through entity tax election instead. Confirm which route fits your ownership group with a CPA before the first year of operation.

Two other Ohio taxes apply regardless of the S election:

• The Commercial Activity Tax at 0.26% above the $6 million exclusion for 2025 and later.
• City net profit tax under Ohio Revised Code chapter 718, at each city's own rate.

Ohio does not charge a franchise tax or an annual LLC tax, and LLCs file no annual report. Those points matter when you compare costs because they mean the S election does not add a separate state filing.

When an S Corp Election Pays (and When It Does Not)

The S election can reduce federal payroll taxes for owners who work in the business and earn more than a reasonable salary. Owners who are paid a salary through payroll pay federal payroll tax on that salary. Profit distributed above the salary is generally not subject to the same federal payroll tax. The savings grow as profit grows, but only if the salary is reasonable for the work performed.

The election may be worth considering when:

• Net profit is well above what you would reasonably pay yourself as a salary.
• You already run payroll, or you expect to hire employees who need payroll anyway.
• You can keep the business records and payroll filings that an S corp requires.

The election may not be worth it when:

• Profit is modest, so the reasonable salary absorbs most of it.
• You expect to reinvest most of the profit in the business and take little cash out.
• The added cost of payroll, a separate federal return, and a CPA outweighs the federal savings.

Ohio's treatment does not change the comparison. The $250,000 deduction, the 3% rate, the CAT, and city tax apply to an LLC and an S corp alike. The comparison comes down to federal payroll tax, the cost of running a compliant S corp, and how much cash you want to take out.

Common Mistakes to Avoid

• Treating the S election as an Ohio filing. Form 2553 goes to the IRS. Ohio has no separate state S election.
• Filing Form 2553 late. The deadline is tied to the tax year, and late relief is not automatic.
• Taking distributions with no salary. An owner-employee who works in the business must be paid a reasonable salary through payroll.
• Using a post office box for the statutory agent. Ohio requires a street address. A P.O. box does not qualify, even one with an associated street address.
• Forgetting the city. Cities tax net profit at their own rates, and the S election does not exempt you.
• Registering a trade name with the county. Trade names are registered with the Secretary of State for $39.00.
• Assuming an annual report is due. Ohio LLCs file no annual report, and for-profit corporations file none either.
• Letting the operating agreement contradict the election. Unequal distribution rights can create a second class of stock, which can put the election at risk.

Expected Results

If you complete these steps correctly, you may end up with a registered Ohio entity, a federal S election that is on file with the IRS, and a payroll process that supports the reasonable salary your business requires. Owners who model the numbers with a CPA before electing often find the decision is clearer, although the outcome depends on profit, salary, and how much cash you take out. Results vary, and no specific tax savings are guaranteed.

Ask a Professional Before You Elect

Ohio's entity and tax rules interact with federal S corp eligibility, city tax, and nonresident owners in ways that are hard to untangle from a checklist. Before you file Form 2553, have an Ohio business attorney review the governing documents and have a CPA model the salary and distribution split. For current fees and deadlines, confirm directly with the Ohio Secretary of State, the Ohio Department of Taxation, and the IRS.
