Illinois Income Tax Overview (2026)

Illinois has a 4.95% flat income tax rate. All income is taxed at this rate regardless of amount — making it simple to calculate. Illinois does not tax Social Security or retirement income, which is advantageous for retirees.

In addition to state tax, all Illinois workers pay federal income tax (10%–37% marginal rates) and FICA — Social Security (6.2%) and Medicare (1.45%), totaling 7.65% of gross wages. Voluntary deductions like 401(k) contributions or health insurance premiums further reduce taxable income.

Cost of Living in Illinois

Illinois costs vary dramatically. Chicago is expensive (median home $340,000; one-bedroom $1,800+/month). Downstate Illinois is very affordable. Property taxes are among the highest in the US, even outside Chicago.

When evaluating a job offer in Illinois, consider not just the salary but total compensation — employer benefits, retirement match, and location-specific costs. A $70,000 salary in a low cost-of-living Illinois city may be more livable than $85,000 in a high-cost metro.

Top Industries and Employers in Illinois

Illinois's economy is anchored by finance, manufacturing, agriculture, healthcare, logistics, technology. The state median household income is approximately $65,000 per year, though this varies significantly by region and occupation.

Illinois's minimum wage of $15.00/hour is more than double the federal floor, which pulls up entry-level pay across the state, and the state's $65,000 median household income sits close to the national average, with finance as the largest single influence on local pay scales.

How Illinois Compares to Other States

Illinois's 4.95% flat rate means a worker earning $75,000 pays approximately $3,712 in state income tax annually. Compared to zero-tax states, this reduces take-home by $3,712/year — a meaningful difference that compounds significantly over a career.

For workers evaluating a potential relocation, state income tax is just one factor.
