Tax Deep Dive
LLC Default Tax
Ohio LLCs default to pass-through taxation, meaning all profits flow through to members' personal tax returns. Members pay Ohio income tax plus federal income tax on their share of profits, regardless of whether money was actually distributed.
C-Corp Tax
Ohio C-Corps face double taxation: the corporation pays 21% federal corporate tax plus Ohio's Commercial Activity Tax on gross receipts. When profits are distributed as dividends, shareholders pay additional personal income tax on those dividends.
When a C-Corp Wins
Whether a C-Corp lowers the total tax depends on your profit, how much of it stays in the business and your own tax bracket, so run the figures with a tax professional.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports published tax rates and statutory attributes, with the sources this page cites. It cannot tell you which structure is better for you: that turns on your profit, the salary you could defend as reasonable compensation, every state you owe tax in, and plans for owners, investors and exit that no figure on this page measures. Confirm your own position with a CPA or tax attorney licensed in your state before you elect anything, because some elections are slow or costly to reverse.
Frequently Asked Questions
Double taxation occurs when a C-Corporation pays corporate income tax on profits, then shareholders pay personal income tax again on dividends, effectively taxing the same income twice. In Ohio, this creates a significant financial burden: your C-Corp pays 21% federal corporate tax plus Ohio's Commercial Activity Tax (CAT) at 0.26% on gross receipts above $6 million annually. When you distribute remaining profits as dividends to shareholders, those dividends face Ohio personal income tax plus federal rates (up to 37%). This compounding effect makes C-Corps substantially more expensive than pass-through structures like LLCs, which avoid entity-level taxation. Review your current business structure with an Ohio CPA to calculate your specific tax burden under both C-Corp and LLC elections.
Whether a C-Corp lowers the total tax depends on your profit, how much of it stays in the business and your own tax bracket, so run the figures with a tax professional. Additionally, C-Corps deduct 100% of health insurance premiums, life insurance, and retirement contributions as business expenses, whereas Ohio LLC owners deduct only 20% of health insurance as a self-employment adjustment. Ohio doesn't charge annual report fees for C-Corps or LLCs, because the Secretary of State requires no periodic reports. However, this strategy only works if you genuinely reinvest earnings; taking distributions eliminates the advantage due to double taxation. Model your specific scenario with a tax professional before filing Articles of Incorporation with Ohio's Secretary of State, since the switch requires separate business accounting.
Yes, you can convert your Ohio LLC to a C-Corp using the conversion process in Ohio's LLC Act, which requires filing a Certificate of Conversion with the Ohio Secretary of State. Alternatively, you can form a new C-Corp and transfer your LLC's assets, though this approach is more cumbersome. The practical implication is significant: statutory conversion preserves your business continuity and existing contracts. The tax result of a conversion depends on how it is done and on the business's assets and debts, so talk to a tax professional before converting. This matters because many investors and venture capital firms require C-Corp structures for institutional funding, making conversion essential for growth-stage businesses. Before proceeding, consult a tax professional to model the conversion's impact on your specific situation, then file your Articles of Conversion with the Ohio Secretary of State.
Venture capitalists overwhelmingly prefer C-Corporations over Ohio LLCs because C-Corps allow VCs to issue preferred stock with liquidation preferences, anti-dilution protections, and board seat rights, terms that are standard for corporate stock but have to be custom-drafted into an LLC's operating agreement. C-Corps also feature standardized governance structures that institutional investors understand and trust, including clear voting mechanisms and fiduciary duties defined by Delaware corporate law (which most VC-backed C-Corps adopt regardless of operating state). Critically, most VC funds are partnerships whose investors include tax-exempt organizations such as pension funds and university endowments. When these funds invest in Ohio LLCs taxed as partnerships, the LLC's income passes through to the VC entity, potentially triggering unrelated business taxable income (UBTI) and creating tax compliance nightmares for the fund's managers and limited partners. For Ohio entrepreneurs seeking VC funding, this means converting your LLC to a C-Corp, either by a statutory conversion or by forming a new corporation with the Ohio Secretary of State, is often a prerequisite before approaching institutional investors, even if your current LLC structure works operationally. Begin exploring conversion requirements immediately if VC fundraising is on your timeline.
Ohio LLCs have no annual filing fee to the Ohio Secretary of State, making them significantly cheaper to maintain than C-Corps. Ohio C-Corporations pay the Commercial Activity Tax (CAT) at 0.26% of taxable gross receipts above the annual exclusion of $6 million; the former $150 minimum tax was eliminated in 2024, and businesses at or below $6 million owe no CAT. This tax applies regardless of profitability, creating a fixed expense that LLCs completely avoid. A corporate tax return and the accounting behind it are added yearly costs, and their price depends on the provider. LLCs filed with Ohio's Secretary of State benefit from pass-through taxation, meaning the business itself pays no income tax, profits pass to owners' personal returns. C-Corps face double taxation: corporate-level taxation plus shareholder dividend taxes. File your LLC formation with the Ohio Secretary of State's Business Services Division and confirm your CAT filing status with the Ohio Department of Taxation if structuring as a C-Corp.
Most small Ohio businesses should choose an LLC because it combines simplicity with tax efficiency without sacrificing liability protection. While Ohio charges a $99 filing fee with the Secretary of State for both LLCs and C-Corporations, LLCs avoid the double taxation burden that corporations face. You won't pay taxes at both the entity and owner level. An LLC taxed as a sole proprietorship or S-Corp offers flexibility unavailable to C-Corps, allowing you to choose your optimal tax treatment annually. Unlike C-Corporations, Ohio LLCs have minimal ongoing compliance requirements; you won't need to file any biennial or annual report with the Ohio Secretary of State, unlike the quarterly filings a corporation faces. Most small business owners lack the complexity that justifies a C-Corp's formal board structure and governance demands. To get started, file your Articles of Organization with Ohio's Secretary of State and obtain an EIN from the IRS. This takes roughly one week total.
