OVERVIEW
Illinois charges a flat 4.95% state income tax with no city income tax — a rare advantage for urban residents. Ohio's state tax is now $332 plus a flat 2.75% above $26,050 (2026, per House Bill 96), but nearly every Ohio city levies its own income tax: Columbus 2.5%, Cleveland 2.5%, Akron 2.5%. At $100,000, an Illinois resident owes ~$4,805 in state income tax; a Columbus resident owes ~$2,313 state plus ~$2,500 city tax — about $4,813 combined, roughly $8 more than Illinois. Rural Ohio wins decisively on income tax. The bigger hidden story is property tax: Illinois averages 1.88% effective (tied for the highest in the US, with New Jersey), while Ohio averages 1.36%. On a $300,000 home, that is $1,560 more per year in Illinois. Chicago also carries one of the highest combined sales tax rates in the country at ~10.5%. Overall: rural Ohio is the clear low-tax winner; urban Ohio roughly matches Illinois once city taxes are factored in (slightly higher at $100K and $150K).

FAQ

Frequently Asked Questions

Who pays less income tax — an Illinois or Ohio resident at $100,000?

It depends where in Ohio you live. A rural Ohio resident owes about $2,313 in state income tax at $100K versus $4,805 in Illinois — Ohio wins by $2,492, thanks to the 2026 flat-tax reform (House Bill 96) that replaced Ohio's old multi-bracket system. A Columbus resident adds 2.5% city tax ($2,500), bringing their combined total to about $4,813 — roughly $8 more than Illinois. An Akron resident (2.5% city tax) is in a similar position. Rural Ohio is the clear winner; urban Ohio is roughly level with Illinois on income tax.

Does Illinois have a city income tax?

No. Illinois is one of the few states where cities — including Chicago — do not levy a local income tax. This is a significant and often overlooked advantage for Illinois urban residents. Ohio, by contrast, has the most extensive city income tax system in the United States, with nearly every municipality charging between 1% and 3%.

What is the Ohio state income tax rate in 2026?

As of tax year 2026, Ohio charges no tax on taxable income up to $26,050, then $332 plus 2.75% of the excess, under House Bill 96 (signed June 2025). This replaced Ohio's previous multi-bracket system, which topped out at 3.5% in 2024 and 3.99% in earlier years. A personal exemption also applies for single filers ($2,400 up to $40,000 of income, $2,150 from $40,001 to $80,000, $1,900 from $80,001 to $500,000). At $100,000, the effective state rate works out to roughly 2.3%.

Which state has higher property taxes — Illinois or Ohio?

Illinois has significantly higher property taxes. The effective average rate is 1.88% in Illinois, tied with New Jersey for the highest in the United States. Ohio averages about 1.36%. On a $300,000 home, that is roughly $5,640 per year in Illinois versus $4,080 in Ohio — a $1,560 annual difference that can easily outweigh income tax savings for homeowners.

How does the Chicago 10.5% sales tax compare to Ohio?

Chicago's combined sales tax of approximately 10.5% is among the highest in the country. Ohio's state rate is 5.75%, and combined local rates typically land between 7% and 8.25%. Groceries are exempt from Ohio sales tax entirely; Illinois ended its 1% state grocery tax on 1 January 2026 (some local 1% grocery taxes remain). Frequent buyers in Chicago pay noticeably more in sales tax than their Ohio counterparts.

Are Social Security benefits taxed in Illinois or Ohio?

No — both Illinois and Ohio fully exempt Social Security benefits from state income tax. Retirees in either state owe zero state income tax on their Social Security income, making both states relatively retirement-friendly on this specific measure.

At $150,000, who wins on total state income tax — Illinois or Ohio?

Rural Ohio wins decisively. An Ohio resident earning $150,000 owes approximately $3,688 in state income tax; an Illinois resident owes $7,280 — a $3,592 annual gap. A Columbus or Akron resident adds 2.5% city tax ($3,750), bringing their Ohio total to roughly $7,438, which is about $158 above Illinois. At this income the city tax flips the result in Illinois's favor for Columbus and Akron residents.

Which state is better for retirees — Illinois or Ohio?

Illinois has a notable retirement advantage: Social Security, pension income, and retirement account distributions (401k, IRA) are all fully exempt from Illinois state income tax. Ohio exempts Social Security but does tax pension and retirement account income above certain thresholds. Property tax is higher in Illinois, but income-light retirees may owe nothing to Illinois and very little to Ohio. The choice often comes down to property tax costs and local city taxes in Ohio.
