Key Takeaways
- Ohio taxes LLC pass-through income at Flat 2.75% on nonbusiness income above $26,050 — but LLC profit usually falls under a separate regime
- Commercial Activity Tax (CAT): 0.26% on Ohio taxable gross receipts above $6 million/year; $0 below that threshold, due Filed quarterly for businesses above the threshold
- Sales Tax: 5.75% (combined: 8.25%)
- Ohio does not require a recurring annual report for LLCs
- Federal self-employment tax of 15.3% applies to net LLC profit regardless of state
- Ohio recognizes the federal S-Corp election automatically with no separate state filing required. The election has no effect on Commercial Activity Tax exposure, since CAT is assessed on gross receipts regardless of entity classification.
- Same-day formation and compliance filing available through LLC Attorney at no markup on state fees
Ohio's tax picture is genuinely good for most LLC owners, but it's also one of the most commonly misunderstood: the widely quoted 2.75% flat income tax rate isn't actually what your LLC profit gets taxed at. Business income gets its own regime — a $250,000 exemption, then a flat 3% above that — and most small LLCs never owe a dollar of the Commercial Activity Tax, since it only applies above $6 million in annual receipts.
This guide covers exactly what an Ohio LLC owes in 2026: the Business Income Deduction and how it differs from the nonbusiness rate, when the Commercial Activity Tax actually applies, why Ohio requires no annual report at all, and whether an S-Corp election is worth the added payroll complexity.
Ohio Personal Income Tax on LLC Profit
By default, an Ohio LLC is a pass-through entity — the LLC itself pays no separate Ohio income tax. Profit flows through to the owners' personal returns, but Ohio taxes that business income under the Business Income Deduction framework rather than the general 2.75% nonbusiness rate: the first $250,000 of pass-through business income per return ($125,000 if married filing separately) is 100% exempt from Ohio tax, and anything above that is taxed at a flat 3%.
Ohio's rate: Flat 2.75% on nonbusiness income above $26,050 — but LLC profit usually falls under a separate regime
Ohio moved to a 2.75% flat rate effective January 1, 2026 — the second-lowest flat rate in the country behind Arizona's 2.5% — applied to nonbusiness income above a $26,050 threshold (income at or below that amount owes $0 state tax). This 2.75% rate does not apply to LLC pass-through profit, which is taxed under Ohio's separate Business Income Deduction regime instead (see below).
This is the single most common misunderstanding about Ohio LLC taxes: founders assume the 2.75% flat rate applies to their business profit. It doesn't — pass-through business income gets its own calculation, with its own exemption and its own rate.
Ohio's Commercial Activity Tax (CAT)
Ohio has no LLC franchise tax and no minimum annual entity fee. The only entity-level tax that can touch an LLC is the Commercial Activity Tax, and it's threshold-triggered at $6 million in annual Ohio gross receipts — most small and mid-size LLCs will never owe a dollar of it, regardless of how they're taxed at the federal level.
The Commercial Activity Tax only applies to businesses with more than $6 million in annual Ohio taxable gross receipts — a threshold raised specifically so the vast majority of small LLCs would owe $0 and not even need to register. Annual CAT filings were eliminated after 2023, so businesses above the threshold now file quarterly only. Ohio recognizes the federal S-Corp election with no separate state election required, and S-Corp status has zero effect on CAT exposure, since CAT is based on gross receipts, not entity type.
Ohio Sales Tax
The state rate is 5.75%, with combined state-and-local rates averaging around 7.3% and reaching up to 8.25% in cities like Reynoldsburg and Pataskala. Register for a Regular Vendor's License through your county Auditor if you have a fixed place of business, or a Transient license through the Department of Taxation if you don't.
- State rate: 5.75%, combined: 8.25%
- Registration: Vendor's License (Regular via county Auditor, or Transient via Department of Taxation), $50 fee with the Ohio Department of Taxation
- There's no renewal fee after the initial $50 Vendor's License, which increased from $25 effective April 9, 2025.
Ohio Annual Report Requirement
Ohio is one of only four states (alongside Arizona, Missouri, and New Mexico) that requires no annual or biennial report for domestic LLCs. The only recurring administrative touchpoint is keeping a valid Statutory Agent on file, which only costs the $25 update fee (Form 521) if that information ever changes.
Federal Self-Employment Tax and How Your Ohio LLC Is Classified
Regardless of which state you're in, LLC owners who materially participate in the business owe federal self-employment tax — 15.3% on net profit, covering Social Security (up to the $184,500 (2026) wage base) and Medicare (no cap).
Single-Member LLCs
A single-member Ohio LLC defaults to a disregarded entity for federal tax purposes — you report income and expenses on Schedule C of your personal Form 1040 and compute self-employment tax on Schedule SE. Ohio taxes that same profit at the state level under the Business Income Deduction framework, not the general 2.75% rate.
Multi-Member LLCs
A multi-member Ohio LLC defaults to partnership taxation, filing an informational Form 1065 and issuing each member a Schedule K-1. There's no Ohio-specific filing consequence tied to member count — the Business Income Deduction applies the same way to both structures.
Should Your Ohio LLC Elect S-Corp Taxation?
An S-Corp election lets you split LLC profit into a reasonable salary (payroll-taxed) and distributions (not subject to self-employment tax), once the business is consistently profitable enough to justify the added payroll complexity.
Ohio's treatment: Ohio recognizes the federal S-Corp election automatically with no separate state filing required. The election has no effect on Commercial Activity Tax exposure, since CAT is assessed on gross receipts regardless of entity classification.
Because the $250,000 Business Income Deduction exemption and 3% flat rate above it apply to pass-through business income regardless of whether you've elected S-Corp status, the Ohio state-tax math for an S-Corp election is largely a wash — electing S-Corp doesn't change how your business income is taxed at the state level. The real driver of an S-Corp election in Ohio remains federal self-employment tax savings, not any Ohio-specific income tax benefit.
Ohio LLC Tax Costs at a Glance
How to Handle Your Ohio LLC's Taxes
If You Do It Yourself
Step 1 — Get your federal EIN before anything else.
Apply for your EIN for free directly at irs.gov — a purely federal application with no Ohio-specific step.
Step 2 — Confirm your default federal tax classification.
A single-member LLC defaults to a disregarded entity (Schedule C); a multi-member LLC defaults to partnership taxation (Form 1065 plus Schedule K-1 for each member). Neither requires a separate election — this is automatic unless you file Form 8832 or Form 2553 to change it.
Step 3 — Register with the Ohio Department of Taxation if required for state income tax withholding or estimated payments.
This is the single most common misunderstanding about Ohio LLC taxes: founders assume the 2.75% flat rate applies to their business profit. It doesn't — pass-through business income gets its own calculation, with its own exemption and its own rate.
Step 4 — Register for sales tax if you sell taxable goods or services.
File Vendor's License (Regular via county Auditor, or Transient via Department of Taxation) with the Ohio Department of Taxation at tax.ohio.gov, $50 fee. There's no renewal fee after the initial $50 Vendor's License, which increased from $25 effective April 9, 2025.
Step 5 — Register for payroll/reemployment tax the moment you hire your first employee.
The moment you hire your first employee, register with the Ohio Department of Job and Family Services (JFS). The 2026 new-employer UI rate is 2.85% (non-construction) or 5.85% (construction), applied to a taxable wage base of $9,500 (up from $9,000), plus a new 0.15% Technology and Customer Service Fee surcharge on wages up to $9,000 for 2026–2027.
Step 6 — Set up quarterly estimated tax payments.
If you expect to owe $1,000 or more in combined federal and Ohio tax for the year, both the IRS and the Department of Taxation expect quarterly estimated payments covering income tax and federal self-employment tax on your LLC profit.
Step 7 — Calendar your Commercial Activity Tax (CAT) due date.
Commercial Activity Tax (CAT) (CAT return (quarterly)) is due Filed quarterly for businesses above the threshold, 0.26% on Ohio taxable gross receipts above $6 million/year; $0 below that threshold. Missing it puts your LLC in bad standing with the Ohio Department of Taxation.
Step 8 — Decide whether an S-Corp election makes sense once your LLC is consistently profitable.
Because the $250,000 Business Income Deduction exemption and 3% flat rate above it apply to pass-through business income regardless of whether you've elected S-Corp status, the Ohio state-tax math for an S-Corp election is largely a wash — electing S-Corp doesn't change how your business income is taxed at the state level. The real driver of an S-Corp election in Ohio remains federal self-employment tax savings, not any Ohio-specific income tax benefit.
Step 9 — Watch for Ohio-specific tax traps.
The Business Income Deduction trap is Ohio's single most important quirk: it's easy to assume the 2.75% flat rate applies to your LLC profit, but business income actually gets a $250,000 exemption followed by a flat 3% rate above that — which can be higher than the 2.75% nonbusiness rate for income just above the exemption threshold. Meanwhile, the CAT's $6 million threshold means most small LLCs can ignore it entirely, which surprises founders coming from gross-receipts-tax states like New Mexico or Washington, where registration is often required regardless of size.
Step 10 — Keep business and personal finances completely separate.
Commingling funds is the single biggest reason courts pierce the LLC liability shield, and it also makes tax preparation far more error-prone. Run all business income and expenses through a dedicated business bank account and keep receipts.

When Should You Talk to a Tax Professional About Your Ohio LLC?

Frequently Asked Questions
No. Ohio has no LLC franchise tax and no annual entity fee. The only entity-level tax that can apply is the Commercial Activity Tax, and it only kicks in above $6 million in annual Ohio taxable gross receipts — the vast majority of small LLCs owe $0 and don't need to register for it at all.
Only if you sell taxable tangible personal property or enumerated services in Ohio. Register for a Vendor's License through your county Auditor (Regular license, for a fixed location) or through the Department of Taxation (Transient license), pay the $50 fee, then collect the 5.75% state rate plus applicable local add-ons, which combine up to 8.25% in some cities.
Ohio requires no annual or biennial report for domestic LLCs — it's one of only four states with that policy. The only recurring obligation is keeping a valid Statutory Agent on file, which only triggers a $25 fee if you ever need to update that information.
Because Ohio has no annual report, there's no report-related deadline to miss. Your main compliance risk is instead keeping your Statutory Agent information accurate, since a lapsed or invalid agent can jeopardize your ability to receive legal notices and maintain good standing.
The Ohio state-tax math for an S-Corp election is largely a wash: the $250,000 Business Income Deduction exemption and 3% flat rate above it apply to your pass-through business income regardless of S-Corp election. The real benefit of electing S-Corp status in Ohio is federal self-employment tax savings, not any additional state income tax break.
A single-member Ohio LLC defaults to a disregarded entity for federal tax purposes — you report income on Schedule C and pay self-employment tax via Schedule SE. Ohio taxes that profit under the Business Income Deduction framework (first $250,000 exempt, 3% flat above that) rather than the general 2.75% nonbusiness rate.
If your LLC does business in a state other than the one it's formed in — an office, employees, inventory, or significant sales there — you may have created nexus requiring registration and tax obligations in that state too. This is fact-specific and worth a conversation with a tax professional if you operate in multiple states.
For a typical Ohio LLC with in-state owners and no employees: the first $250,000 of business income is exempt from Ohio tax under the Business Income Deduction, with a flat 3% rate above that (not the 2.75% nonbusiness rate), no annual report fee, and no Commercial Activity Tax unless you exceed $6 million in Ohio gross receipts — plus federal income tax and 15.3% federal self-employment tax (up to the $184,500 Social Security wage base for 2026). Add 5.75%–8.25% sales tax only if you sell taxable goods or services.
Yes. LLC Attorney's ongoing compliance subscription tracks your Ohio filing deadlines, handles your annual report, and connects you with flat-fee attorney consultations (no retainer) when a tax question needs a licensed professional's judgment call.
