Ohio Payroll Tax: Withholding, SUTA, and Employer Filing

Running payroll in Ohio means handling seven distinct tax obligations: federal income tax withholding, Social Security and Medicare (FICA), federal unemployment (FUTA), Ohio state income tax withholding at a flat 2.75%, school district income tax in 210 districts, municipal income tax in hundreds of cities and villages, state unemployment insurance paid to the Ohio Department of Job and Family Services, and workers’ compensation premiums paid directly to the Ohio Bureau of Workers’ Compensation. Ohio payroll taxes are unusually layered because of the local income taxes that ride on top of the state rate, and each layer has its own registration, filing schedule, and penalty structure.

Federal Payroll Taxes

Every Ohio employer owes the same federal payroll taxes as employers in any other state. Social Security is 6.2% of each employee’s wages up to the annual wage base of $184,500 in 2026, matched by the employer. Medicare is 1.45% on all wages with no cap, also matched. Employees earning more than $200,000 in a calendar year owe an extra 0.9% Medicare surtax on wages above that threshold; the employer withholds it but does not match it.1Social Security Administration. Contribution and Benefit Base

The employer’s combined share of Social Security and Medicare is 7.65% of every wage dollar up to the Social Security cap. Deposits go to the IRS on a schedule tied to total tax liability, and quarterly totals are reported on Form 941. This is the biggest single payroll tax line for most Ohio businesses, and it sits on top of everything Ohio-specific below.

Ohio State Income Tax Withholding

Any employer maintaining an office or doing business in Ohio must withhold state income tax from employee wages.2Ohio Legislative Service Commission. Ohio Revised Code 5747.06 – Employers Duty to Withhold Tax Beginning January 1, 2026, Ohio uses a flat 2.75% rate on nonbusiness income above $26,050. Wages at or below that threshold generate no state tax, so lower-paid workers may see little or no state withholding on their checks.

The tax commissioner sets the withholding tables employers use each pay period, calibrated so annual withholding tracks the employee’s actual liability.2Ohio Legislative Service Commission. Ohio Revised Code 5747.06 – Employers Duty to Withhold Tax Every employee completes Form IT 4, which tells the employer how many personal exemptions to apply and identifies the employee’s school district of residence.3Ohio Department of Taxation. Form IT 4 – Employees Withholding Exemption Certificate

School District Income Tax

Ohio has 210 school districts that levy their own income tax as of January 2026, and employers must withhold it from employees who live in a taxing district.4Ohio Department of Taxation. School District Income Tax Rates run from 0.25% to 2.00% depending on the district.5Ohio Department of Taxation. School District Tax Year 2026 School district tax is residence-based, not work-based, which makes it a different animal than municipal tax.

Each taxing district has a four-digit code that the employee reports on the IT 4. The Ohio Department of Taxation runs an online lookup called “The Finder” where you can enter an address and get the correct district number.3Ohio Department of Taxation. Form IT 4 – Employees Withholding Exemption Certificate A wrong code either sends money to the wrong district or skips the withholding entirely, and both problems show up at year-end. When an employee moves, they need to file a new IT 4 with the updated code.

Municipal Income Tax

Hundreds of Ohio cities and villages levy their own income tax. Current rates range from zero in a handful of places up to 3% in cities like Parma Heights and Bedford, with most municipalities between 1% and 2.5%.6Regional Income Tax Agency. Tax Rates Table Many jurisdictions outsource collection to the Regional Income Tax Agency (RITA) or the Central Collection Agency (CCA), so filings often go to one of those rather than directly to the city.

The default rule: withhold for the municipality where the employee physically performs the work. If the employee lives in a city with a higher rate, they may owe the difference to their home city, and credit rules for tax paid to the work location vary by jurisdiction. For employers whose workers move between cities, tracking which employee worked where on which days is the tedious part. Keep clean records of work locations and home addresses to avoid double-taxation disputes.

Ohio Unemployment Insurance (SUTA)

Ohio employers pay state unemployment insurance to the Ohio Department of Job and Family Services on the first $9,000 of each employee’s wages per year.7Ohio Department of Job and Family Services. Contribution Rates Nothing comes out of the employee’s check; this one is entirely on the employer.

New employers without a claims history pay a standard rate of 2.85% for 2026. Construction is the exception, where new employers pay 5.85%.7Ohio Department of Job and Family Services. Contribution Rates After enough claims history accumulates, the state assigns an experience rating that can run from 0.1% to 6.5%, depending on how much former employees have collected in benefits.8Ohio Legislative Service Commission. Ohio Revised Code Chapter 4141 – Unemployment Compensation Stable workforces pay far less than businesses with heavy turnover.

Federal Unemployment Tax (FUTA)

FUTA applies to the first $7,000 of each employee’s wages. The nominal rate is 6.0%, but employers who pay state unemployment on time and in full get a 5.4% credit, dropping the effective rate to 0.6%, or a maximum of $42 per employee per year.9U.S. Department of Labor. FUTA Credit Reductions

The credit shrinks if a state has borrowed from the federal government to cover unemployment benefits and hasn’t repaid within two years, producing what’s called a credit reduction that raises the effective FUTA rate for that state’s employers.9U.S. Department of Labor. FUTA Credit Reductions Ohio has stayed off that list in recent years, but check annually.

Workers’ Compensation

Ohio is a monopolistic workers’ compensation state. Private carriers are not an option; every employer pays premiums directly to the Ohio Bureau of Workers’ Compensation, which then covers medical costs and lost wages for on-the-job injuries. Premium rates depend on industry classification and reported payroll, so an office operation pays far less per payroll dollar than a roofing crew.

Letting coverage lapse creates outsized risk. The BWC can impose a lapse retroactive to the first day of the month nearest the missed payment date. During that lapse period the employer has no coverage, meaning any workplace injury becomes direct personal liability. Missing filings or payments can also remove you from all rating plans and discount programs, and the BWC may recalculate premium using estimated payroll increased by 10%.10Ohio Legislative Service Commission. Ohio Administrative Code 4123-17-16 – Penalties: Late Payment and Reporting Late payments accrue interest at the rate set by the state tax commissioner. The total cost of a lapse runs well beyond the overdue premium.

Registering Your Business

Start with a Federal Employer Identification Number (EIN) from the IRS. Then register with the Ohio Department of Taxation for state and school district withholding, which is administered through OH|TAX eServices.11Ohio Department of Taxation. Business Registration Open an unemployment insurance account with the Ohio Department of Job and Family Services, and set up a workers’ compensation policy with the BWC.

For municipal taxes, register with each city where you have employees working, or with the collection agency (RITA or CCA) that handles that city’s tax. The setup phase is registration-heavy, but each one is free.

Filing Schedules and Penalties

How often you file Ohio employer withholding depends on your combined state and school district withholding during a 12-month lookback period ending June 30 of the prior year:12Ohio Department of Taxation. Employer Withholding

Most small employers file quarterly. Payments go through electronic funds transfer, and each submission generates a confirmation number worth saving as proof of filing. Late filing and late payment both trigger penalties. Ohio’s individual income tax late filing penalty runs 5% of tax due per month up to 50%, plus a late payment penalty at double the annual interest rate.14Ohio Department of Taxation. Ohio Individual Income Tax Failure to File Notice Employer withholding penalties follow a similar structure.

New Hire Reporting

Every Ohio employer must report each new employee to the Ohio New Hire Reporting Center within 20 days of the hire date, and the requirement also covers independent contractors.15Ohio.gov. New Hire Reporting The report captures name, address, Social Security number, and employer details, feeding the state’s child support enforcement system and helping detect unemployment fraud. Failing to report doesn’t trigger the size of penalties that missing a tax payment does, but it does leave you exposed to state fines and puts you offside a federal mandate.

Record Keeping

The IRS requires employment tax records be kept for at least four years after the tax becomes due or is paid, whichever is later.16Internal Revenue Service. Topic No. 305, Recordkeeping Use that same window for Ohio filings. Hold every IT 4, quarterly and annual withholding return, unemployment filing, workers’ compensation payroll report, and municipal return for at least four years. If the Department of Taxation or BWC audits you, organized records from the relevant period are the fastest way out. Businesses that discard records after two or three years regularly lose the ability to challenge assessments they could otherwise have defeated.
