Ohio levies a graduated personal income tax but, unusually, does not impose a traditional corporate income tax on most businesses; instead it taxes business activity through the Commercial Activity Tax (CAT), a gross-receipts tax. The state also runs a statewide sales and use tax that combines with county and transit-authority rates, and it imposes lodging taxes that matter directly to hotels, campgrounds, and short-term-rental operators. Most of these taxes are administered by the Ohio Department of Taxation, with the CAT and sales tax filed through the state's online systems.

Ohio levies a graduated personal income tax but, unusually, does not impose a traditional corporate income tax on most businesses; instead it taxes business activity through the Commercial Activity Tax (CAT), a gross-receipts tax. The state also runs a statewide sales and use tax that combines with county and transit-authority rates, and it imposes lodging taxes that matter directly to hotels, campgrounds, and short-term-rental operators. Most of these taxes are administered by the Ohio Department of Taxation, with the CAT and sales tax filed through the state's online systems.
Ohio has a graduated personal income tax that applies to residents and to nonresidents on Ohio-source income, and recent legislation has been steadily consolidating and lowering the brackets over time. Because Ohio does not tax most businesses at the entity level on net income, owners of sole proprietorships, partnerships, S corporations, and LLCs generally report their share of business profits on their individual Ohio returns via Schedule K-1. Ohio also offers a notable Business Income Deduction that lets qualifying owners exclude a portion of their pass-through and self-employment business income from Ohio taxable income, with income above that exclusion taxed at a separate flat business-income rate; this deduction is a meaningful planning lever that does not exist in most other states.
Ohio is one of the few states with no broad corporate income tax on net profits; instead it imposes the Commercial Activity Tax (CAT), a tax on a business's taxable gross receipts sourced to Ohio rather than on profit, which applies across most entity types including C corporations, LLCs, and partnerships once a receipts threshold is met. Because the CAT is a gross-receipts tax, even low-margin or unprofitable businesses can owe it, and recent law changes have raised the exclusion threshold so that many smaller businesses now fall below the filing requirement entirely. Ohio also allows a pass-through entity (PTE) tax election that lets eligible S corporations and partnerships pay Ohio tax at the entity level as a workaround to the federal SALT deduction cap, and financial institutions pay a separate Financial Institutions Tax instead of the CAT. Because the CAT threshold, the PTE election, and entity choice interact differently for each business, the right structure should be confirmed against current Ohio Department of Taxation guidance.
Ohio imposes a statewide sales and use tax, and individual counties (and certain transit authorities) add their own local rates on top, so the combined rate a business charges varies by the county where the sale is sourced. Remote sellers and marketplace facilitators that exceed Ohio's economic-nexus thresholds for either sales volume or transaction count must register, collect, and remit Ohio sales tax even without any physical presence in the state. Businesses with physical locations, inventory, or employees in Ohio must register through the Ohio Business Gateway and collect at the combined state-plus-county rate for each jurisdiction where their sales are sourced.
Ohio's sales tax generally applies to short-term lodging, and on top of that, counties, municipalities, and townships are authorized to levy their own lodging (transient occupancy) excise taxes on hotel rooms, campsites, cabins, and short-term rentals, so a single booking can carry both state sales tax and one or more local lodging taxes. Because these lodging taxes are largely locally enacted and administered, the rate and the filing office differ from one Ohio jurisdiction to the next, and an operator with locations in multiple counties may file several separate lodging-tax returns. Hosts who rent through online marketplaces should not assume the platform remits every applicable tax; marketplace collection often covers state sales tax but may leave the operator responsible for registering and filing local lodging taxes directly with the county or municipality.
Most Ohio businesses register and file through the Ohio Business Gateway, which handles sales and use tax, employer withholding, the Commercial Activity Tax, and other state accounts in one place. Sales tax is typically filed on a recurring cadence (monthly or semiannually) that the state assigns based on tax volume, the CAT is filed by registered taxpayers on its own schedule, and income and PTE returns are filed annually alongside the entity's return. Operators should keep detailed records of Ohio-sourced gross receipts (for the CAT), county-level taxable sales, exemption certificates, and lodging tax collected and remitted, because the split between state-administered taxes and locally administered lodging taxes is the most common compliance gap for multi-location and hospitality businesses.
Ohio's reliance on a gross-receipts CAT instead of a corporate income tax changes the planning math for owner-operators: there is no profit-based state corporate tax to manage, but the CAT can apply regardless of margin, so high-revenue, low-margin operators feel it differently than they would in an income-tax state. For campground, RV-park, hotel, and short-term-rental operators, the bigger exposure is usually the patchwork of locally enacted lodging taxes layered on top of state sales tax, since these are enacted county-by-county and city-by-city and are easy to miss when entering a new Ohio market. The Business Income Deduction on the personal return is a further genuine lever for pass-through owners and should be coordinated with the PTE election rather than treated in isolation.
Parikh Financial keeps Ohio owner-operators compliant across the state's distinctive mix of a gross-receipts Commercial Activity Tax, county-level sales tax, and locally administered lodging taxes, while tracking economic nexus as clients sell or operate across state lines. For STR, campground, and hospitality clients especially, we handle Ohio Business Gateway registration, jurisdiction-by-jurisdiction lodging-tax remittance, and the Business Income Deduction and PTE-election decisions that determine how much Ohio tax owners actually pay.
