What Is the Ohio Withholding Tax Rate for Employers?

The Ohio withholding tax rate for 2026 is a flat 2.75% on an employee’s taxable wages above $26,050. Below that threshold, no state income tax is withheld. The same 2.75% rate applies to supplemental compensation such as bonuses.¹ Most Ohio employers also withhold school district and municipal income taxes on top of the state amount, so the single state rate is only part of what comes out of a paycheck.

How the 2.75% Rate Applies

Under Ohio Revised Code 5747.02, taxable income of $26,050 or less carries no state income tax. Above that amount, the tax is $332.00 plus 2.75% of the excess over $26,050.² There is one rate for everyone above the floor. Employers don’t need to apply different percentages to different slices of income.

To translate that annual math into a per-paycheck deduction, employers use the Ohio Department of Taxation’s withholding tables, which are keyed to pay frequency (weekly, biweekly, semi-monthly, or monthly). The current tables took effect October 1, 2025 and apply through 2026.¹

The input for the tables comes from Form IT 4, Ohio’s Employee’s Withholding Exemption Certificate. Each employee completes it at or before the start of employment, listing personal exemptions for themselves, a spouse, and dependents. More exemptions mean less wages subject to withholding. The form also lets an employee request an additional flat dollar amount per pay period, which is useful when someone expects to owe more than the standard tables will cover.³

School District Income Tax

Many Ohio school districts levy their own income tax, ranging from 0.25% to 2.00% depending on the district. The rate is added to the state withholding amount and is based on where the employee lives, not where they work.⁴

Each district uses one of two tax bases. A “traditional” district taxes the same income taxed at the state level. An “earned income” district taxes only wages and self-employment earnings.⁵ For most wage earners the practical result is the same, but an employee with investment income will owe more under a traditional district.

Employers need each employee’s four-digit school district code to apply the correct rate. The Department of Taxation’s free lookup tool, The Finder, matches a street address to its district and rate.⁶ Employees report their district on Form IT 4; verifying through The Finder prevents underwithholding or sending money to the wrong district.

Municipal Income Tax

Hundreds of Ohio cities and villages impose their own income tax, and unlike school district tax, municipal tax generally follows where the employee works. A resident of one city who commutes to another may owe tax in both places, though most municipalities offer a credit for tax paid to the work city so the employee is not fully taxed twice.⁷

Rates vary widely. Some small municipalities charge 1%; others exceed 2%. Any rate above 1% generally requires voter approval if the municipality did not already have a higher rate before March 2015.⁷

The 20-Day Occasional Entrant Rule

If an employee works in a given municipality for 20 or fewer days in a calendar year, the employer does not have to withhold that city’s income tax for that employee.⁸

The exemption falls away if the municipality is the employee’s principal place of work, if the job site is expected to last more than 20 days, or if the employee is a professional athlete or entertainer. A day only counts toward the 20 if the employee spent more time working in that city than in any other city on the same day.⁸

Workers Who Live in Neighboring States

Ohio has reciprocal tax agreements with Indiana, Kentucky, Michigan, Pennsylvania, and West Virginia. Residents of those states who earn wages in Ohio are exempt from Ohio income tax withholding; the arrangement runs in reverse for Ohio residents working across those borders.⁹

To claim it, the employee checks the reciprocity box in Section 2 of Form IT 4 and certifies out-of-state residency.³ Without that form on file, the employer must withhold Ohio tax as if the employee were an Ohio resident. The employee has to take the initiative; the employer cannot assume reciprocity based on an address alone.

When Withheld Tax Is Due

Ohio sorts employers into one of four payment frequencies based on total withholding during the 12-month period ending June 30 of the prior year:

Quarterly, if total withholding was $2,000 or less. Payment is due by the last day of the month following the end of each calendar quarter: April 30, July 31, October 31, and January 31.
Monthly, if total withholding was more than $2,000. Payment is due within 15 days after the end of each month.
Partial-weekly, if total withholding was $84,000 or more. Payment is due within three banking days after the close of each partial-weekly withholding period.
Next banking day, for any employer that accumulates $100,000 or more in undeposited withholding during a single partial-weekly period.

These thresholds and deadlines are set by Ohio Revised Code 5747.07.¹⁰ All payments go through the Ohio Business Gateway.¹¹

Penalties for Getting It Wrong

The consequences break down by type of violation under Ohio Revised Code 5747.15:¹²

Late filing: the greater of up to $50 per month (capped at $500) or 5% of the tax due per month (capped at 50%).
Failing to remit withheld taxes: up to 50% of the delinquent payment. Withholding is money held in trust for the state, and keeping it is treated accordingly.
Fraud: up to the greater of $1,000 or 100% of the tax that should have been reported.

Interest accrues on any unpaid balance at 7% per year for 2026. The officer or employee responsible for filing and payment can be held personally liable, so the business entity does not shield individuals from the obligation.¹
