Ohio Income Tax Calculator 2026 — Estimate Your Ohio State Tax

October 27, 2026 · 3 min read · By the DollarWise team

Ohio overhauled its income tax into a simple flat tax: 2.75% on Ohio taxable income above $26,050, and 0% at or below it. There is no standard deduction — instead, a personal exemption per person that shrinks as income rises. Enter your income and number of exemptions and this calculator estimates your Ohio state tax, your effective rate, and the monthly equivalent. It is a planning estimate only: it excludes municipal and school-district income taxes, which most Ohio cities levy separately at roughly 1–3%.

How it works

Ohio’s 2026 income tax is a flat 2.75% on Ohio taxable income above $26,050 — there is no standard deduction and no bracket ladder. Your personal exemption depends on income: $2,400 per person at $40,000 or less, $2,150 at $40,001–$80,000, and $1,900 above $80,000. The formula is: tax = max(0, income − exemptions − $26,050) × 2.75%.

Worked example: $75,000 single, 1 exemption. The exemption is $2,150 (income in the $40,001–$80,000 band), so taxable income is $75,000 − $2,150 − $26,050 = $46,800, and tax is $46,800 × 2.75% = $1,287.
