S-Corp Election in Ohio (Form 2553) (2026)

Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

To elect S-corporation status in Ohio, you file IRS Form 2553 with the IRS - generally within 2 months and 15 days after the start of the tax year the election takes effect. Ohio recognizes the federal S election with no separate state election. Ohio has no corporate income tax, but a Commercial Activity Tax (CAT) applies to gross receipts above an exemption threshold.

What an S-Corp Election Actually Is

An "S corporation" is not a type of legal entity - it is a federal tax status that an eligible corporation or LLC elects by filing IRS Form 2553. The underlying entity is still an Ohio corporation or LLC; the election changes only how it is taxed. Instead of the entity paying corporate income tax on its profits, an S corporation is a pass-through: profits and losses flow to the owners' personal returns, avoiding double taxation.

Owners choose S status mainly to reduce self-employment tax. In a default LLC, all net earnings are subject to self-employment tax. With an S election, only the owner-employee's wages are subject to payroll tax, while remaining profit distributed to the owner is not - provided the salary is reasonable. Compare the structures in S-corp vs LLC.

Because the election has real payroll, accounting, and compliance consequences, it is not automatically right for every business. It generally makes sense once profits comfortably exceed a reasonable salary for the owner's role. Below are the eligibility rules, the deadline, how Ohio treats the election, the state taxes, and the salary requirement.

Eligibility Requirements for Form 2553

To qualify to elect S status, the entity must meet strict federal requirements at all times. It must be a domestic corporation or an LLC eligible to be taxed as a corporation. It may have no more than 100 shareholders, and all shareholders must be eligible: U.S. citizens or residents, certain trusts and estates, and specific tax-exempt organizations. Partnerships, corporations, and nonresident aliens cannot be shareholders.

The entity may have only one class of stock, meaning all shares confer identical rights to distributions and liquidation proceeds (differences in voting rights are allowed). It must also use a permitted tax year, generally the calendar year. An LLC electing S status is treated as having made an entity classification election as well.

If any requirement is broken later - for example, an ineligible shareholder acquires stock - the S election can terminate, returning the entity to C corporation taxation. Because the rules are unforgiving, confirm eligibility before filing and keep ownership within the limits. The IRS instructions to Form 2553 list every condition in detail.

The Filing Deadline and Late-Election Relief

Timing is the most common trap. To take effect for a given tax year, Form 2553 must generally be filed no later than 2 months and 15 days after the beginning of that tax year, or at any time during the preceding tax year. For a calendar-year business, that means roughly March 15 to elect S status effective January 1 of the same year.

New entities count the 2-month-and-15-day window from the date the business first has shareholders, acquires assets, or begins doing business - whichever is earliest. Missing the deadline pushes the election to the following year unless you qualify for relief.

The IRS provides late-election relief (under Revenue Procedure 2013-30) for entities that intended to be S corporations, had reasonable cause for filing late, and are otherwise eligible. You request it by filing Form 2553 with a reasonable-cause statement, often within 3 years and 75 days of the intended effective date. Do not rely on relief as a plan - file on time whenever possible.

How Ohio Treats the S Election

Ohio does not require a separate state S-corporation election. An entity that is an S corporation for federal purposes is recognized as one for Ohio tax, so filing Form 2553 with the IRS is normally the only election you make. Ohio's pass-through income then flows to owners, who report it on their Ohio individual income tax returns filed with the Ohio Department of Taxation.

Ohio is notable for having no traditional corporate income tax on most businesses. Instead, its major entity-level business tax is the Commercial Activity Tax (CAT) on gross receipts, discussed below. For pass-through entities with nonresident investors, Ohio also has withholding and composite filing options (such as the IT 1140), and it offers an elective pass-through entity tax.

You still register the business with the Ohio Secretary of State as an entity and maintain a statutory (registered) agent. Because Ohio's business tax structure differs from most states, confirm current rules with the Department of Taxation. See Ohio LLC tax filing for detail.

Ohio Commercial Activity Tax and the PTE Election

The Commercial Activity Tax (CAT) is Ohio's tax on the privilege of doing business, measured by taxable gross receipts rather than profit. Ohio has raised the CAT exemption in recent years, so businesses with gross receipts below the exclusion threshold owe no CAT and may not even need to register - a change that removed many small businesses from the CAT entirely. Confirm the current threshold with the Department of Taxation, as it has been increasing.

Because the CAT is based on gross receipts, an S corporation can owe it regardless of whether it is profitable, once it exceeds the exclusion. It is separate from the owners' individual income tax on pass-through profit.

Ohio also offers an elective pass-through entity (PTE) tax (filed on Form IT 4738) that lets the S corporation pay Ohio tax at the entity level, a workaround for the federal cap on state-and-local-tax deductions. Whether it helps depends on the owners' situations, so review it with a tax professional alongside the CAT. See the business tax hub.

Reasonable Compensation and Filing Steps

The tax savings from an S election depend on paying yourself a reasonable salary. If you work in the business, the S corporation must pay you reasonable W-2 wages - subject to Social Security and Medicare tax - before taking additional profit as distributions, which are not subject to those payroll taxes. Paying an artificially low salary is a well-known audit target.

"Reasonable" means what a comparable business would pay someone for the same work, considering duties, experience, and industry norms. The S corporation must run payroll, deposit payroll taxes, and file employment returns, and in Ohio it registers for state and applicable municipal wage withholding and unemployment insurance. These added costs are why the election typically pays off only once profits exceed a reasonable salary.

Practically: confirm eligibility, get an EIN, file Form 2553 by the deadline with all shareholder consents, keep the IRS acceptance notice, and plan to file federal Form 1120-S each year plus any Ohio CAT and PTE filings. Because the election touches payroll and both federal and Ohio taxes, many owners work with a CPA. This page is general information, not tax advice.

Frequently Asked Questions

What form do I file for an S-corp election in Ohio?

You file IRS Form 2553 with the IRS. Ohio does not have a separate state election - it recognizes your federal S status. Ohio S corporations then report pass-through income to owners and may owe the Commercial Activity Tax.

What is the deadline to file Form 2553?

Generally within 2 months and 15 days after the start of the tax year the election should take effect, or during the prior tax year - about March 15 for a calendar-year business. Late-election relief may be available for reasonable cause.

Does Ohio have a corporate income tax on S corporations?

No. Ohio has no traditional corporate income tax on most businesses. Instead it imposes the Commercial Activity Tax on taxable gross receipts above an exemption threshold, and owners pay Ohio individual income tax on pass-through profit.

What is the Ohio Commercial Activity Tax?

The CAT is Ohio's tax on the privilege of doing business, measured by taxable gross receipts rather than profit. Ohio has raised the exemption, so many small businesses below the threshold owe no CAT and may not need to register.

Do S-corp owners in Ohio need to take a salary?

Yes, if they work in the business. The IRS requires owner-employees to receive reasonable W-2 wages subject to payroll taxes before taking profit distributions. Paying too little salary to avoid payroll tax is a common audit trigger.
