Sales Tax on Cleaning Services in Ohio (2025)

Ohio Exempts Small Operators Below $5,000 and Carved Out Beer-Tap Cleaning by Court Order

Ohio taxes "building maintenance and janitorial service" directly under Ohio Revised Code §5739.01(B)(3)(j), with the operative definition supplied at §5739.01(II): cleaning the interior or exterior of a building and any tangible personal property located therein or thereon, including incidental services for which no separate charge is made. What distinguishes Ohio from most other states in this batch is a genuine small-business threshold built directly into the statutory definition, not a separate registration exemption layered on top, providers with less than $5,000 in building maintenance and janitorial sales during the calendar year fall outside the definition of a taxable vendor for this specific service category entirely. Cross that threshold mid-year, and the obligation to collect applies going forward from that point, tracked by the Ohio Department of Taxation's Information Release ST 2002-04, which gives concrete examples of covered activity: washing, vacuuming, dusting, polishing, and waxing.

Ohio also has one of the more colorful pieces of cleaning-tax case law in the country. In Great Lakes Bar Control, Inc. v. Testa, 2018-Ohio-5207, the Ohio Supreme Court held that cleaning draft beer-tap lines does not constitute a taxable "janitorial service" under the statute, reasoning that the ordinary meaning of janitorial cleaning centers on general building upkeep, and that beer-line cleaning is fundamentally a maintenance service where any cleaning aspect is incidental to keeping the equipment functioning properly, not the primary character of the service. The case is a useful precedent for any specialty maintenance business, HVAC cleaning, equipment servicing, industrial line cleaning, weighing whether their specific scope fits the ordinary meaning of "janitorial" or sits closer to equipment maintenance that happens to involve cleaning as a secondary effect.

Ohio Building Maintenance and Janitorial Service Taxability

Rate Structure and Registration

Ohio's base state rate is 5.75 percent, with county-level add-ons ranging from 0.75 to 2.25 percent, producing combined rates typically between 6.5 and 8 percent depending on the specific county. Registration happens through the Ohio Business Gateway, and once a cleaning business crosses the $5,000 annual threshold, it must register for a vendor's license and begin collecting tax on all taxable building maintenance and janitorial sales for the remainder of that year and going forward. Because the threshold is measured on a calendar-year basis, a growing business needs to monitor cumulative year-to-date sales in this specific service category, not overall company revenue, since a company might have significant revenue from an exempt service line, say, equipment repair under the Great Lakes Bar Control framework, while its actual janitorial-specific sales stay under $5,000.

Worked Example: A $10,000 Monthly Contract Well Above the Threshold

A cleaning business generating $10,000 a month from a single commercial contract has obviously cleared the $5,000 annual threshold many times over, so the full contract is taxable. Using a representative Franklin County (Columbus) combined rate of 7.5 percent (5.75 percent state plus local additions), the calculation is: $10,000 × 0.075 = $750 in sales tax collected from the client and remitted to Ohio's Department of Taxation. The client's total invoice reads $10,750. Contrast this with a very small solo operator earning $400 a month, or $4,800 annually, from occasional residential cleaning jobs, that operator stays under the $5,000 threshold and collects no sales tax at all on those services, provided the cumulative annual total does not cross the line. The moment that operator picks up one more recurring client that pushes annual janitorial-specific revenue past $5,000, registration and collection become mandatory going forward.

Applying the Great Lakes Bar Control Test to Your Own Service Menu

If your business offers anything beyond straightforward building cleaning, HVAC coil cleaning, dryer vent cleaning, specialized equipment sanitization, the Great Lakes Bar Control precedent gives you a genuine analytical framework rather than just a beer-industry anecdote. The Ohio Supreme Court's reasoning centered on whether the ordinary understanding of "janitorial service" would include the specific activity in question, or whether the activity is better characterized as equipment maintenance where cleaning is incidental to a broader mechanical or functional purpose. A dryer vent cleaning service focused on fire-safety compliance and airflow restoration, for example, has a real argument for falling outside "janitorial service" under this same logic, similar to how beer-tap cleaning was found to be about equipment function rather than general building upkeep. This is not a blanket exemption for any service with "cleaning" somewhere in its description, but it is worth a documented legal analysis, potentially with an Ohio tax attorney, before assuming a specialty maintenance service must be taxed just because your invoice uses the word "cleaning" somewhere in the description.

The department's sales and use tax section is where county rate changes and subsequent information releases are posted, and county rates vary enough here that a contractor with accounts in three counties administers three combined rates. Participation in the Streamlined Sales Tax Governing Board as a full member adds a certified definitional layer through the annual matrix, which is the document to cite when a national customer's tax department questions why building maintenance is invoiced with tax in this state and not in another.

Tracking the $5,000 Threshold Through a Growth Year

Ohio's threshold calculation deserves more operational attention than most operators give it, because it is measured specifically against building maintenance and janitorial sales, not total company revenue, which means a business with diversified service lines needs a dedicated running total for this one category rather than a glance at overall bank deposits. A company that started the year believing it would stay under $5,000 based on its existing contract book, then picked up two new recurring commercial accounts mid-year, needs to recognize the exact month cumulative janitorial-specific sales crossed the threshold and begin collecting tax from that point forward, not retroactively from January and not delayed until the following calendar year. Ohio's Department of Taxation does not send a warning notice when a business approaches this threshold, the responsibility to track it and register in time sits entirely with the taxpayer.

Because vendor's license registration through the Ohio Business Gateway is not instantaneous, businesses approaching the threshold should start that registration process a few weeks before they expect to cross $5,000 in cumulative annual sales, rather than waiting until the exact month they cross the line, to avoid a gap between when collection should have started and when the registration is actually active.
