Are Employers Required to Withhold Local Taxes in Ohio?

Ohio employers are generally required to withhold local income tax from employee wages, and the rule for local tax withholding in Ohio ties the obligation to the municipality where the employee physically performs the work, not where the company is based or where the employee lives. The duty is set by Ohio Revised Code Section 718.03, and the penalties for missing it can reach 50% of the unwithheld tax.¹ The details below walk through who has to withhold, for which city, and when the standard rule bends.

Withhold for the City Where the Employee Works

The core obligation is to withhold municipal income tax for the employee’s “principal place of work.” That phrase has a specific statutory meaning: the fixed location where the employee is required to report on a regular and ordinary basis. If there is no such fixed location, it becomes the worksite the employee reports to most often. If neither applies, it defaults to the municipality where the employee spends the most working days in the calendar year.²

An employee who commutes from an untaxed township into an office in Columbus generates a Columbus withholding obligation at Columbus’s rate. The company’s headquarters address does not enter the calculation, and neither does the employee’s home address.

Withholding for the Employee’s Home City Is Optional

Ohio does not require employers to withhold for the municipality where an employee lives. The statute says an employer “may also deduct and withhold, on the request of an employee, taxes for the municipal corporation in which the employee is a resident.”¹ Some employers offer this as a courtesy; many do not.

When an employer doesn’t provide courtesy withholding, the employee handles the home-city tax directly, usually through quarterly estimates or a lump payment on the annual municipal return. Employees often ask why nothing was taken out for their hometown, and the answer is that the law does not require it.

The 20-Day Occasional Entrant Rule

Employees who occasionally work in other municipalities do not trigger withholding on day one. Under Section 718.011, if an employee works in a municipality other than their principal place of work for 20 or fewer days in a calendar year, the employer keeps withholding for the principal place of work and ignores the other city.²

On day 21, withholding for the new municipality begins and continues for every additional day worked there through the rest of the calendar year. The count resets January 1.²

Two limits worth knowing. The exemption does not apply to professional athletes, professional entertainers, or public figures, who are subject to withholding from the first day. And work performed at a petroleum refinery triggers withholding after 12 days rather than 20.²

The Small Employer Shortcut

Ohio offers a simpler path for small employers. A “small employer” is one with gross receipts under $500,000 in the preceding tax year that also has a fixed location in Ohio.³ A qualifying small employer withholds based only on the municipality where its fixed location sits, regardless of where employees actually perform services.²

If that fixed location sits in a taxing city, the employer withholds at that city’s rate for all employees. If the fixed location is in a jurisdiction with no local income tax, the small employer has no municipal withholding obligation at all.

Gross receipts include reimbursements from any party, so a business that looks small by revenue can cross the $500,000 line once reimbursements are counted. Check the total each year if you’re close to the threshold.

Remote and Hybrid Employees

Remote work often flips the answer employers expect. Under Ohio’s definitions, an employee’s home is not a “worksite location.”² That distinction changes how the principal-place-of-work test resolves. When a remote employee is not required to report to a fixed office on a regular basis, the principal place of work becomes the municipality where the employee spends the greatest number of working days, which for a fully remote worker is usually where they live.

So an employer with an office in Dayton whose employee works full-time from home in Columbus would typically withhold for Columbus, not Dayton. For hybrid arrangements, the employer needs to track actual days at the office and at home and apply the 20-day occasional entrant thresholds against those counts.

Build withholding tracking around where employees physically sit each day, not around the location of the office or the payroll system.

School District Income Tax Is Separate

On top of municipal tax, Ohio employers must withhold school district income tax from employees who live in a taxing school district. As of 2026, 210 Ohio school districts impose an income tax. School district tax follows the employee’s residence, not the worksite, which is the opposite of the municipal rule.⁴

The trigger is Form IT 4. If the employee completes Section II of the IT 4, the employer withholds the applicable school district tax. If the employee doesn’t complete an IT 4 at all, the employer will not withhold school district tax, even if the employee actually lives in a taxing district.⁵ That employee can owe a lump sum plus penalties at filing time. Flag incomplete IT 4 forms at hire rather than processing them silently.

Registration, W-2 Reporting, and Filing

Employers must register with the tax authority for each municipality where they have a withholding obligation. Many Ohio cities outsource collection to the Regional Income Tax Agency (RITA) or the Central Collection Agency (CCA), so a single registration can cover dozens of jurisdictions. Filing schedules and payment deadlines vary by the administering agency and the size of the employer’s withholding liability.

At year-end, local tax information goes on each employee’s W-2 in Box 18 (local wages), Box 19 (local income tax withheld), and Box 20 (locality name).⁶ When an employee triggered withholding for more than one municipality during the year, report each city separately. Employees rely on these entries to file their municipal returns and to claim any resident credit their home city allows.

Penalties for Failing to Withhold

Ohio Revised Code Section 718.27 lets municipalities impose penalties directly on employers who fail to withhold or remit on time. Three consequences apply:

Interest on all unpaid withholding tax, at a per-annum rate set by the municipality.
A withholding penalty of up to 50% of the amount not paid on time.
A late filing penalty of up to $25 per return, though municipalities must waive this the first time a taxpayer files late.⁷

The 50% figure is the one that stings. An employer that should have withheld $10,000 over a year and didn’t can face a $5,000 penalty plus compounding interest. These amounts remain the employer’s liability even if the employee eventually pays the underlying tax directly.⁷
