Four state income tax brackets. Six hundred-plus school districts with their own levies. City taxes on top of that. Ohio payroll taxes 2026 carry more moving parts than nearly any neighboring state — and the costliest compliance gaps open before you run a single paycheck. Here's every obligation your business carries this year, laid out straight.
- State income tax: graduated brackets from 2.765% to 3.99% — withheld from every employee paycheck
- School District Income Tax (SDIT): up to 3% additional tax based on where your employee lives, not where they work
- State Unemployment Insurance (SUI): new employer rate typically 2.7% on first $9,000 of wages
- Local income taxes: Columbus (2.5%), Cleveland (2.0%), Cincinnati (1.8%) — based on work location
Ohio Payroll Tax Rates at a Glance (2026)
Ohio runs a graduated state income tax — no flat rate, no shortcuts. The Ohio Department of Taxation updates withholding tables every year, so confirm your payroll software is pulling 2026 figures specifically. The four brackets:
| Taxable Income | Rate |
|---|---|
| Up to $26,050 | 2.765% |
| $26,050 – $100,000 | 3.226% |
| $100,000 – $115,300 | 3.688% |
| Above $115,300 | 3.99% |

Federal obligations layer on top: FICA at 7.65% split between employer and employee (6.2% Social Security + 1.45% Medicare), plus FUTA at 6% on the first $7,000 per employee — reduced by SUI credits. New to the full picture? Small Business Payroll 101 covers the federal layer in plain terms.
School District Income Tax (SDIT): The Ohio Wildcard
SDIT is what separates Ohio from simpler states. Over 600 school districts levy their own income tax on top of the state rate — and no two are identical. Rates run roughly 0.5% to 3% depending on the district, and you cannot guess. You have to look it up for every employee.
You must withhold SDIT based on where your employee lives, not where they work. An employee who commutes from a taxing school district into Columbus still owes SDIT to their home district — and you're on the hook to withhold it.
Use the Ohio Department of Taxation's school district lookup at tax.ohio.gov — you'll need each employee's home address. Then register for each applicable district separately via the Ohio Business Gateway. Missing even one is the most common compliance gap among Ohio small employers.
Not all Ohio school districts tax the same income base. Some use earned income only (wages and self-employment), while others use the traditional method (all Ohio taxable income, including investment income). This affects your withholding calculation — check the specific district's tax type when you register.
What that oversight costs in practice: a Dayton HVAC shop owner hired three techs from three different townships. State withholding: correctly set up. Two school district registrations: missed entirely. The result was back taxes, penalties, and amended returns. A five-minute address check at onboarding would have stopped it cold. Before finalizing your setup, read through common payroll mistakes to avoid.

SUI Rates, Local Taxes & Getting Registered
Ohio SUI in 2026
Ohio's State Unemployment Insurance runs through the Ohio Department of Job and Family Services (ODJFS). New employers land at a 2.7% rate on the first $9,000 of each employee's annual wages. Experienced employers get rates between 0.3% and 9.8% based on claims history — recalculated annually. File quarterly via OJI; returns are due the last day of the month following each quarter end.
Local City Income Taxes
Ohio cities tax wages earned within their limits. That's based on where your employees work — not where they live. The three major metros:
| City | Local Tax Rate | Administered By |
|---|---|---|
| Columbus | 2.5% | Columbus Income Tax Division |
| Cleveland | 2.0% | CCA (Central Collection Agency) |
| Cincinnati | 1.8% | Cincinnati Income Tax Division |
Most Ohio municipalities run collections through RITA or CCA. A physical location or employees working inside a covered city means registration is mandatory. Ohio's tax structure runs deeper than nearby states like Indiana or Pennsylvania — worth knowing if you operate across state lines.
Employer Registration Checklist
Register with the Ohio Department of Taxation via Ohio Business Gateway for state income tax withholding.
Register with ODJFS for SUI withholding and quarterly filing.
Look up each employee's school district using the ODT lookup tool, then register separately for each applicable SDIT via Ohio Business Gateway.
Register with RITA or CCA (or the city directly) if any employees work in a municipality with a local income tax.

Ohio Payroll Compliance: Key Deadlines for Micro-Businesses
Most small Ohio employers withholding under $2,000 per month file state income tax withholding quarterly. Withhold more, and ODT may move you to monthly or semi-weekly deposits — check your filing frequency classification when you register. SUI is always quarterly: due April 30, July 31, October 31, and January 31. Stack those alongside your federal Form 941 deadlines. Our Q4 Payroll Deadlines 2026 guide has the full federal calendar.
"Miss one school district registration and you could owe back taxes plus penalties — SDIT is the #1 compliance gap for Ohio small employers."
Ohio requires employers to issue itemized pay stubs showing all deductions — no exceptions. Household or domestic employees in Ohio fall under the same state withholding rules; the Household Employee Taxes 2026 guide covers those specifics. One hard rule applies everywhere: pay records must reflect actual wages paid. Falsifying income documents is illegal.
Ohio has more moving parts than most states — four income tax brackets, 600+ school districts with separate registration requirements, city-level taxes, and quarterly SUI filings. Once the setup is complete, ongoing compliance is manageable. Getting every registration right on Day 1 is what matters most, especially SDIT. A payroll tool built for small employers handles bracket math and district lookups automatically. See how PayHRoll handles Ohio payroll for small businesses.
Frequently Asked Questions
Does Ohio have a flat payroll tax rate for employers?
No. Ohio uses a graduated state income tax with four brackets ranging from 2.765% to 3.99%. Employees may also owe school district income tax (SDIT) depending on where they live — a separate withholding obligation that adds another 0.5% to 3% on top of state tax.
What is the Ohio school district income tax and do I have to withhold it?
SDIT is an additional income tax levied by more than 600 Ohio school districts. Withholding is based on each employee's home address — not the worksite. Rates range from 0.5% to 3%, and you must register with Ohio's Department of Taxation for each applicable district separately via the Ohio Business Gateway.
What is the Ohio SUI rate for new employers in 2026?
New employers are assigned a 2.7% SUI rate on the first $9,000 of each employee's wages per year. Experienced employers see rates between 0.3% and 9.8% based on unemployment claims history, recalculated annually by ODJFS.
Do I need to withhold both state tax and local city tax?
Yes, if your business has a physical presence in a taxing municipality. Local city taxes — Columbus's 2.5%, for example — apply to wages earned within that city. State income tax and SDIT are separate on top of that. All three can apply to a single employee paycheck depending on where they live and work.
