Ohio's Commercial Activity Tax (CAT)
a low rate applied to a very broad base, with a substantial annual exclusion that has been raised in recent years — which has taken many smaller businesses out of the filing requirement entirely.
Because it is calculated on revenue rather than on profit, a business here can owe it in a year it lost money. The billing consequence is specific: CAT is on gross receipts, not profit, so a low-margin business can owe it in a loss-making year. Tracking Ohio-sitused receipts separately through the year is what makes the return a lookup rather than a reconstruction. That is a chart-of-accounts decision rather than a year-end adjustment, which is why we set it up during onboarding rather than discovering it at filing time.
How Ohio affects your billing
We track your Ohio taxable sales against the $100,000 in sales or 200 transactions threshold, keep the liability account reconciled to what you actually collected, and prepare and file the return on your assigned cadence. When collected tax does not tie to the return, that gap is a real liability — we find it during the monthly close rather than at year-end.
None of this is a service we sell, and none of it is advice — it is reference, kept because a practice is still a business with a state footprint and the question comes up. See how Medicaid billing works in Ohio or browse everything for Ohio.
White Glove Medical Billing is a medical billing, coding, and revenue cycle company — not a healthcare provider and not a law firm. All coding is performed by certified coders from your providers' documentation; the clinical record and the certification of medical necessity remain the provider's. Coverage determinations, claim adjudication, payment amounts, and appeal outcomes are decided solely by the applicable payer, plan, or government program. Rules, fee schedules, and timely-filing limits change and vary by payer and by state; collections, reimbursement, turnaround times, and appeal results are not guaranteed and will differ by practice.
