How to Use This Ohio Income Tax Calculator
This Ohio income tax calculator estimates your annual state and federal tax liability for 2025 and 2026. Enter your gross income, filing status, and any pre-tax deductions above, then select your Ohio city in the Localitydropdown. Selecting your city is important — Ohio's municipal income tax often adds more to your bill than the state income tax itself.
This tool focuses on your annual tax picture — useful for tax planning, comparing job offers, or estimating what you owe at filing time. For a per-paycheck breakdown, use the Ohio paycheck calculator; to compare Ohio with other states, use the general income tax calculator.
How Ohio State Income Tax Works
Ohio uses a progressive bracket system that has been simplified over recent years. For 2026, there are only two brackets:
- 0% on the first $26,050 — the zero-rate tier effectively exempts low-income Ohioans entirely and provides significant relief to middle-income earners.
- 2.75% on income above $26,050 — a single rate applies to all remaining income regardless of how high it goes.
Ohio does not have a standard deduction. Ohio taxable income is generally equal to federal adjusted gross income (with some state-specific adjustments), minus any applicable exemption credits applied after tax is calculated. For most wage earners, this means more income is exposed to Ohio brackets than to federal brackets.
Ohio's top marginal rate has fallen dramatically: from 8.87% in 1982, to 5.925% in 2005, to 4.797% in 2019, to 3.99% in 2022, to 3.5% in 2023, to 3.5% in 2024, to 3.125% in 2025, and now 2.75% in 2026. The state legislature has signaled intent to continue reducing the rate in future years.
Ohio Municipal Income Tax — A Critical Second Layer
Ohio is one of the only states where a significant share of workers owe more in local city tax than in state income tax. Over 600 Ohio municipalities levy a local income tax on wages earned within their borders.
How it is calculated
The municipal tax generally applies to gross wages earned in the city — with most municipalities recognizing pre-tax 401(k) and Section 125 deductions. There is no zero-rate tier at the city level; the rate applies from the first dollar. A Columbus resident earning $50,000 owes:
- Ohio state tax: 0% × $26,050 + 2.75% × $23,950 = $659
- Columbus municipal tax: 2.5% × $50,000 = $1,250
The municipal tax ($1,250) is nearly twice the state tax ($659) for this earner. This dynamic reverses for very high earners, but for incomes under ~$60,000, city tax typically dominates.
Work city vs. resident city
Ohio taxes wages at the location where the work is performed. If you live in a suburb and work in Columbus, you owe Columbus 2.5%. Your suburban city may also levy a resident income tax, but must offer a credit for tax paid to the work city. Depending on the suburb, the credit can be 0%–100% — check your resident city's ordinance.
FICA Taxes — Social Security and Medicare
FICA is federal and applies to every Ohio paycheck:
- Social Security: 6.2% on wages up to $176,100 (2025) or $184,500 (2026). No further withholding once you hit the wage base.
- Medicare: 1.45% on all wages with no cap.
- Additional Medicare: 0.9% on wages above $200,000 (single) or $250,000 (married jointly) — employee only, no employer match.
Step-by-Step Example — $90,000 Ohio Single Filer in Dayton (2026)
- Gross wages: $90,000
- Federal standard deduction: −$16,100 → federal taxable income: $73,900. Federal income tax: ~$11,870.
- FICA: 7.65% × $90,000 = $6,885.
- Ohio state tax: 0% × $26,050 + 2.75% × $63,950 = $1,759.
- Dayton municipal tax: 2.25% × $90,000 = $2,025.
- Total taxes: $11,870 + $6,885 + $1,759 + $2,025 = $22,539
- Annual net income: $90,000 − $22,539 = $67,461
How to Reduce Your Ohio Annual Tax Liability
- Maximize traditional 401(k) contributions — the 2026 limit is $23,500 ($31,000 if 50+). At a combined 2.75% OH state + 2.5% Columbus city + 22% federal = 27.25% marginal rate, every $1,000 contributed saves $272.50 in taxes.
- Contribute to an HSA — $4,300 (self-only) or $8,550 (family) in 2026. Reduces federal, Ohio, and municipal taxable income while also avoiding FICA when contributed through payroll.
- Review your municipal residency credit— if your employer withholds city tax for your work city, check your resident city's rate and credit. If your suburb's rate is lower than Columbus's 2.5%, you may owe nothing extra at the resident level.
- Ohio Opportunity Zone investments — Ohio provides a 10% nonrefundable income tax credit for investments in certified Ohio opportunity zones; useful for business owners and high-income investors.
- File the Ohio IT-1040 carefully— Ohio allows deductions for Social Security benefits, military pay, certain business income (small business investor deduction), and contributions to Ohio's 529 CollegeAdvantage plan. These subtractions reduce Ohio AGI before the brackets apply.
