Cincinnati's income tax is 1.8%, effective October 2, 2020, down from 2.1%. Employers withhold it on pay to Cincinnati residents wherever they work and on pay to nonresidents for services performed in the city, and income of individuals under 18 is exempt. Ohio taxes cleaning except for a provider with less than $5,000 in calendar-year sales of that service.
Cincinnati's income tax applies to anyone who lives or works in the city, so payroll is where it lands for a cleaning company. Below: the rate, who it's withheld from, the annual W-3, Ohio sales tax on cleaning, and what it means for your books. State payroll registration is on my Ohio page.
Cincinnati's 1.8% income tax
The City of Cincinnati Income Tax Division lists the rate at 1.8%, effective October 2, 2020; it was 2.1% before that. It applies to anyone who lives or works in Cincinnati (the city's FAQ phrases it as individuals age 18 or older), and residents get credit for tax paid to other cities up to 1.8%.
Withholding works off the 2025 Form W-3 definition: compensation paid to nonresidents for services performed in Cincinnati, plus compensation paid to Cincinnati residents wherever performed, multiplied by 1.8%. Income of individuals under 18 is exempt. Employers remit semi-monthly, monthly, or quarterly, and the pages this one draws on don't quote the thresholds for each. The year closes with an annual W-3 reconciliation; the 2025 one is due March 2, 2026.

Sales tax on cleaning
Ohio taxes residential and commercial cleaning, except for a provider with less than $5,000 in sales of that service in a calendar year. Window washing and carpet cleaning are on the taxable list; cleaning outdoor pools isn't. The state rules are on my Ohio sales tax page.

What this means for your books
The W-3 at year end is a reconciliation, and that's my favorite kind of form. Every single dollar of city tax withheld during the year should tie back to a paycheck, an employee, and whether that person lived in Cincinnati or worked there. Withheld city tax sits in its own liability account, apart from Ohio withholding, and employees under 18 are flagged on their payroll record. Payroll goes in at the wage actually paid; my payroll page covers the setup.
I'm a bookkeeper, not a CPA or an Enrolled Agent. I keep the withholding recorded and traceable; how often you remit, and how the W-3 and any sales tax returns get filed, are questions for your CPA.
