Understanding Your Take-Home Pay in Illinois
Illinois has a flat state income tax of 4.95%, meaning every dollar of taxable income is taxed at the same rate regardless of how much you earn. Combined with federal income tax and FICA, Illinois workers face a meaningful total tax burden. However, the flat rate means the calculation is straightforward — and Illinois does not tax retirement income, which is a notable advantage for retirees.
Illinois Flat Tax: How It Works
Unlike progressive-tax states like California or New York, Illinois taxes all income at the same 4.95% rate. The state offers a personal exemption of $2,625 per person (so $5,250 for a married couple). After subtracting the exemption, the remaining income is taxed at the flat rate. On a $72,000 salary, that works out to roughly $3,439 in state tax for a single filer. See how this compares to federal taxes using our US Salary Calculator.
Property Taxes: The Hidden Cost
While the income tax rate is moderate, Illinois has some of the highest property taxes in the nation, averaging 2.07%. In Cook County (Chicago), effective rates can exceed 2.5%. This means homeowners in Illinois may face a higher total tax burden than the income tax alone suggests. Use our Illinois Mortgage Calculator to see how property taxes affect your housing costs.
Chicago vs. Downstate
While there is no city income tax in Chicago, the city has a high combined sales tax rate of 10.25% and various other taxes and fees. Downstate Illinois generally has lower property taxes and a lower cost of living, though job opportunities are more concentrated in the Chicago metro area. When evaluating an Illinois job offer, consider the full picture: income tax, property tax, sales tax, and cost of living all vary significantly by location.
