Ohio Nonprofit & Charitable Organization Audits
Ohio does not impose a statewide audit requirement on nonprofits under its Charitable Trust Act, but audited financial statements are routinely required by major Ohio funders — including the Cleveland Foundation, the Columbus Foundation, the Greater Cincinnati Foundation, the George Gund Foundation, the Lincoln Electric Foundation, the United Way affiliates, and federal subrecipient grantors. We deliver nonprofit audits that meet major funder expectations and Form 990 supporting requirements.
Ohio 401(k) & Employee Benefit Plan Audits
Ohio plan sponsors filing Form 5500 generally require an ERISA-compliant audit when the plan has 100 or more participants with account balances at the start of the plan year — the participant-counting rule effective post-SECURE 2.0.

We align the assurance level, support schedules, and delivery timeline with the actual credit, surety, diligence, or capital request.
Ohio Reviews & Compilations
For manufacturers, healthcare professionals, insurance executives, real estate investors, and small business owners benefiting from the CAT reform, review or compilation work is often the right fit when a bank, acquirer, board, grantor, or owner needs CPA-prepared financial statements but a full audit is not required.

Ohio (OH) Tax & Business Landscape
Key Ohio Tax Numbers. Personal income tax: graduated, with a recently simplified bracket structure — 0% on the first ~$26,050 of taxable income, 2.75% on income up to ~$100,000, and 3.5% top rate on income above $100,000. Municipal income tax: most Ohio cities and villages impose 1% to 3% on wages and net business profits earned in the municipality (collected by RITA, CCA, or directly). Commercial Activity Tax (CAT): 0.26% gross receipts tax — but with major recent reform: businesses with $3 million or less in Ohio gross receipts are exempt for tax year 2024, and businesses with $6 million or less are exempt starting tax year 2025. Sales and use tax: 5.75% state plus local; combined typically 6.5%–8%. Estate tax: none (repealed 2013). Pass-through entity (PTE) elective tax: available since tax year 2022 via Form IT 4738. For manufacturers, healthcare professionals, insurance executives, real estate investors, and small business owners benefiting from the CAT reform, these numbers matter most when entity structure, owner compensation, residency, property, or investment decisions change the federal and state result.
Filing Mechanics. Individuals (residents and nonresidents and part-year residents) file Form IT 1040. Pass-through entities can elect into the PTE tax via Form IT 4738; pass-through withholding is on Form IT 1140. Commercial Activity Tax is filed quarterly or annually with the Ohio Department of Taxation. Municipal income tax returns are filed with RITA (Regional Income Tax Agency), CCA (Central Collection Agency), or the municipality directly — depending on jurisdiction. Returns are due April 15. We use those mechanics to build a filing calendar and document request list for manufacturers, healthcare professionals, insurance executives, real estate investors, and small business owners benefiting from the CAT reform before deadlines compress the planning options.
The CAT Reform & Municipal Tax Web. Ohio's recent dramatic increase in the CAT exclusion threshold (from $150K to $3M in 2024 and $6M in 2025) effectively eliminates the tax for most small and mid-sized Ohio businesses — a significant tax reduction we help clients confirm and capture. Separately, Ohio's complex municipal income tax web (with multiple collection agencies and city-by-city rules) remains a major compliance burden for multi-city employers, remote workers, and traveling professionals. We handle both routinely.
Ohio Economy & Who We Serve. Ohio's economy is anchored by manufacturing (Honda Marysville auto plant, GM, Ford, P&G HQ in Cincinnati, Goodyear in Akron), healthcare (Cleveland Clinic — among the world's top-ranked hospitals), insurance (Columbus — Nationwide HQ; Cincinnati — Western & Southern, Cincinnati Financial), banking (Fifth Third, KeyBank, Huntington), agriculture (corn, soybeans, dairy), energy (Marcellus and Utica Shale natural gas in eastern Ohio), aviation/aerospace (Wright-Patterson AFB in Dayton, NASA Glenn in Cleveland), and a growing tech/AI sector (the Intel semiconductor plant in New Albany). Our typical OH clients include manufacturers, healthcare professionals, insurance executives, real estate investors, and small business owners benefiting from the CAT reform.
CPA Mobility in Ohio. We serve clients nationwide under CPA mobility rules where applicable. Before accepting Ohio work for manufacturers, healthcare professionals, insurance executives, real estate investors, and small business owners benefiting from the CAT reform, we confirm the engagement type, CPA mobility, firm registration, and any attest or state-sensitive requirements.

Ohio CPA — Frequently Asked Questions
Do I need an Ohio-licensed CPA, or can an out-of-state CPA handle my OH tax and audit work?
CPA mobility often allows an out-of-state CPA in active good standing to serve Ohio clients, but the right answer depends on the engagement type. For manufacturers, healthcare professionals, insurance executives, real estate investors, and small business owners benefiting from the CAT reform, we confirm whether the work is tax, advisory, attest, employee-benefit-plan, or state-sensitive before accepting the engagement.
What is Ohio's income tax rate, and when is the OH return due?
Ohio has a graduated personal income tax with a top rate of 3.5% on income above $100,000 (a recently simplified bracket structure: 0% on the first ~$26,000, 2.75% on the next bracket, 3.5% on income above $100,000). However, most Ohio municipalities also impose a local income tax of 1% to 3%, often making the effective combined rate substantially higher. Form IT 1040 is due April 15.
What is the Ohio Commercial Activity Tax (CAT), and what are the recent threshold changes?
The Ohio Commercial Activity Tax is a 0.26% gross receipts tax on most businesses operating in Ohio. Under recent reform, the CAT exclusion threshold was raised dramatically: businesses with $3 million or less in Ohio gross receipts are exempt for tax year 2024, and businesses with $6 million or less are exempt starting tax year 2025. This change effectively eliminates CAT for most small and mid-sized Ohio businesses — a significant tax reduction that we help clients confirm and capture.
Does Ohio have a SALT-cap workaround for partnerships and S-corps?
Yes. Ohio enacted an elective Pass-Through Entity Tax effective for tax years beginning on or after January 1, 2022. Eligible S-corps and partnerships file Form IT 4738 and pay an entity-level tax tracking the top personal income tax rate, with members receiving a corresponding credit on IT 1040.
Why does Ohio have so many municipal income tax filings, and what are RITA and CCA?
Most Ohio cities and villages impose their own income tax (1% to 3%) on wages earned and net business profits within the municipality. Compliance is collected by the Regional Income Tax Agency (RITA) for some cities, by the Central Collection Agency (CCA) for others, and by the municipality directly for the rest. Multi-city employers and remote workers can face filings in multiple municipalities. We handle Ohio's complex municipal tax web routinely.
When does my Ohio nonprofit need an audit?
Ohio does not impose a state-mandated audit threshold for nonprofits under its Charitable Trust Act. Audited financial statements are typically required by lenders, federal grantmakers, the Cleveland Foundation, the Columbus Foundation, the Greater Cincinnati Foundation, the Lincoln Electric Foundation, and similar major Ohio funders. Federal Single Audit requirements under 2 CFR Part 200 apply when federal award expenditures exceed $1,000,000 in a fiscal year.
Do you serve Ohio clients outside Columbus, Cleveland, and Cincinnati?
Yes. Our practice is virtual-first, so we serve clients across all of Ohio — including Toledo, Akron, Dayton, Parma, Canton, Youngstown, Springfield, Lima, the Cleveland metro suburbs, the Columbus metro suburbs, the Cincinnati metro and Northern Kentucky border, the Mahoning Valley, and every Ohio county — with the same level of access and service.
