Healthcare Accounting in Ohio
Ohio has no corporate income tax, which is the headline most out-of-state CPAs stop at. The real work for Ohio clinic owners with $1M to $50M in revenue is the Commercial Activity Tax on gross receipts (0.26% above the $6M 2025 exclusion, with Medicare and Medicaid receipts often excludable), municipal income tax across RITA and CCA cities like Cleveland, Columbus, and Cincinnati, and plan-by-plan Medicaid realization across eight MCOs plus OhioRISE. Cleveland Clinic and OhioHealth referral gravity shapes the specialty economy.
Financial leadership for Ohio clinics competing in a Cleveland Clinic and OhioHealth market
Ohio has four distinct healthcare metros, three dominant systems, and a gross receipts tax instead of a corporate income tax. Your accountant needs to know all of that.

Ohio Healthcare Landscape
What it actually looks like to run an outpatient clinic in Ohio
Ohio is a healthcare market that punches above its weight. Cleveland Clinic alone sees millions of outpatient visits a year and anchors one of the most referenced health systems in the world. Columbus has OhioHealth, Mount Carmel, and the Ohio State Wexner Medical Center all fighting for a rapidly growing metro. Cincinnati has TriHealth, UC Health, and Bon Secours Mercy Health. Dayton, Akron, Toledo, and Youngstown each have their own smaller systems. For a state with around 11.8 million people, Ohio has an unusual density of top-50 nationally ranked hospitals.
What that means for independent clinic owners is a referral economy that is built around a handful of very large players. You either build strong physician-to-physician referral relationships with system-employed specialists, or you build a destination-style independent practice that bypasses the referral pattern entirely (concierge medicine, direct pay aesthetics, self-referring dental). There is not really a middle lane.
Ohio's economic profile favors clinics. Cost of living is 8-10% below the national average, real estate is cheap relative to coastal markets, and wages for clinical staff in Cleveland, Columbus, and Cincinnati run meaningfully below New York or California equivalents. The tradeoff is a payer mix that includes a higher-than-average Medicare and Medicaid share, and a commercial PPO market dominated by Anthem, Medical Mutual of Ohio, and UnitedHealthcare. Margins are workable here if you run a tight operation and understand Ohio-specific tax treatment. They are not forgiving if you do not.
Dominant outpatient specialties
Ohio has been one of the most active states in the country for physical therapy, dermatology, and dental PE roll-ups over the last five years. If you are running an independent specialty group and you have not had an inbound inquiry, you are either very small or well hidden.
- Cardiology, with one of the deepest community cardiology benches in the US outside academic centers
- Orthopedics and sports medicine, particularly around Columbus and Cincinnati
- Oncology, with strong community oncology groups competing alongside CCF and OSU
- Dermatology and Mohs, with active consolidation across the Cleveland and Columbus metros
- Behavioral health and substance use, driven by Ohio's ongoing opioid response funding
- Dental and DSO-aligned dental groups, with large independent operators in Columbus and Cincinnati
Major systems you compete against
Ohio's three metros each have their own dominant systems. What looks like one statewide market is really three local markets with very different referral patterns and payer leverage.
Cleveland Clinic
Cleveland's dominant academic medical system; massive destination-care referral network that pulls volume in from across the country.
OhioHealth
Columbus-anchored not-for-profit with 14 hospitals and 200+ ambulatory sites across central and southeastern Ohio.
Mercy Health (Bon Secours Mercy Health)
Largest Catholic system footprint in Ohio; deep presence in Cincinnati, Toledo, Youngstown, and Lima.
University Hospitals
Cleveland-based academic system with 20+ hospitals and extensive ambulatory expansion across Northeast Ohio.
Mount Carmel Health System
Trinity Health affiliate anchoring Columbus with four hospitals and a growing outpatient network.
Tax & Regulatory
The Ohio rules your accountant should already know
Ohio eliminated its corporate income tax over a decade ago and replaced it with the Commercial Activity Tax (CAT), a gross receipts tax with thresholds and exclusions most non-Ohio CPAs get wrong on the first try. The rules changed meaningfully in 2024 and again in 2025.
No corporate income tax
Ohio does not levy a corporate income tax. C corp profits are not taxed at the state level. Owner distributions through S corps, partnerships, and LLCs are taxed on individual returns at Ohio's personal income tax, which tops out at 3.125% for 2025, with a planned move to a flat 2.75% effective 2026.
Commercial Activity Tax (CAT)
Ohio taxes gross receipts through the CAT. Beginning 2024, the annual exclusion increased to $3M. Beginning 2025, the exclusion rose to $6M, meaning only receipts above $6M are taxed at 0.26%. Medicare and Medicaid receipts, plus certain other excluded receipts, can be excluded from the gross receipts base. For a $10M healthcare clinic with a 40% Medicare/Medicaid mix, the CAT bill is much smaller than the headline math suggests, but only if you file correctly.

Corporate Practice of Medicine
Ohio enforces the corporate practice of medicine doctrine. Only licensed physicians may own shares in a professional association or professional medical corporation. Professional LLCs are allowed but carry similar ownership restrictions. Any MSO or friendly-PC structure for a DSO/PE transaction must comply with Ohio State Medical Board rules.
Sales and use tax on medical supplies
Ohio exempts prescription drugs, most prosthetic devices, and durable medical equipment prescribed for home use. Med spa retail products, aesthetic supplies not incident to treatment, and many ancillary items are taxable. Ohio has been more aggressive on med spa and aesthetic practice sales tax audits in the last three years.
Municipal income tax
Ohio cities levy their own income tax on top of the state. Cleveland, Columbus, Cincinnati, and most mid-size cities charge 2.0% to 2.5% on business net profits earned within city limits. For a clinic with multiple locations across the state, municipal apportionment is a real line item that is often mishandled by out-of-state CPAs who do not know the RITA and CCA filing systems.

Local Market Dynamics
The market forces that show up on every Ohio P&L
Ohio's cost advantages are real but narrowing. Clinic owners who do not track wage, payer, and referral dynamics closely end up with margin compression they did not see coming.
System referral gravity
Cleveland Clinic, OhioHealth, and UC Health have been steadily employing specialists and redirecting referrals internally. Independent specialty practices that relied on hospital-based PCPs for referrals are finding that pipeline narrower every year. The practices that have replaced it most successfully built direct patient marketing or locked in relationships with the remaining independent primary care groups.
Ohio Medicaid managed care
Ohio Medicaid delivers most of its managed care through multiple MCOs (Aetna, AmeriHealth Caritas Ohio, Anthem, Buckeye, CareSource, Humana, Molina, UnitedHealthcare Community Plan, plus OhioRISE for behavioral health). Plan-level realization varies meaningfully by service line. CareSource is the largest plan in the state and disproportionately present in central Ohio.

Wage environment
Medical assistant pay in Columbus and Cincinnati climbed roughly 15 to 25% between 2020 and recent BLS Occupational Employment and Wage Statistics releases, pushed by system hiring competition and the Amazon and Intel labor demand in central Ohio. Cleveland has moved up more slowly but is still meaningfully higher than pre-pandemic. Downstate Ohio (Dayton, Youngstown, Lima) stays lower-wage, but the labor pool is thinner.
Real estate remains favorable
Medical office space in Columbus and Cincinnati runs roughly half the cost per square foot of Chicago or Philadelphia, and far below coastal markets. For a clinic expanding regionally, Ohio real estate economics make second- and third-location buildouts more forgiving than most other markets.
How Sorso Helps Ohio Clinics
Healthcare-specialized accounting and CFO support, built for Ohio operating reality
Ohio clinics we work with are typically independent specialty practices working through system referral shifts, or multi-location groups expanding across metros. We focus on the reporting infrastructure that makes those transitions controlled rather than reactive.
- •Monthly accounting with location- and provider-level P&Ls so you can see which sites and which providers are actually profitable.
- •Fractional CFO support for Ohio clinics in the $3M to $50M range, including CAT gross-receipts planning with Medicare and Medicaid exclusions applied, Cleveland Clinic and OhioHealth referral drift tracking, and CareSource plan-level realization analysis.
- •CAT filing support that correctly excludes Medicare and Medicaid receipts, plus proper use of the $6M 2025 exclusion.
- •Municipal tax apportionment across RITA and CCA cities for multi-location operators.
- •Specialty support for cardiology, orthopedics, dermatology, dental, mental health, and ASC-integrated surgical practices.
If the CAT exclusion for Medicare and Medicaid receipts, the municipal income-tax mix across Cleveland/Columbus/Cincinnati, and your plan-level CareSource and Buckeye realization are not in the monthly pack, you are flying blind on about a third of your P&L.
Common questions from Ohio clinic owners
Do we owe CAT if we are under $6M in gross receipts?
Starting 2025, the CAT exclusion increased to $6M. Below that, you generally owe nothing but may still have a registration and reporting obligation depending on prior-year receipts. Above $6M, only the portion above the exclusion is taxed at 0.26%. Importantly, Medicare and Medicaid receipts are often excludable from gross receipts, which drops the taxable base for most healthcare clinics meaningfully. We see this exclusion missed regularly by national CPA firms unfamiliar with Ohio healthcare rules.
We operate in Cleveland and Columbus. How does municipal tax work?
Ohio cities administer their own income taxes, most through RITA or CCA. A clinic with locations in both Cleveland and Columbus will file city returns in each and apportion net profits based on payroll, property, and receipts in each city. The apportionment math matters because rates and rules differ by city. Cleveland is 2.5%, Columbus is 2.5%, Cincinnati is 1.8%. Getting apportionment wrong costs real money either way.
Cleveland Clinic is taking our referral volume. What do we do about it financially?
This is a real and common problem. The financial fix is twofold: track referral source data inside your practice management system so you can actually see the trend, and model the contribution margin of the patients you keep versus the patients CCF captures. Then make decisions about direct patient marketing, out-of-system partnerships, and service line mix based on real numbers. Most independent practices we work with in Northeast Ohio do not have the data to see this clearly until we build the reports.
