Income tax = max(0, income − deductions) × 4.95%; sales tax = purchase × county rate (Cook 10.25%, DuPage 7.75%, Lake 8.00%, other 7.25%); property tax = property value × county rate (Cook 2.10%, DuPage 1.90%, Lake 2.20%, other 2.00%).
About the Illinois Tax Calculadora
Illinois stacks a flat individual income tax with local sales taxes and property taxes that vary by county. A household comparing Chicago with a collar-county suburb needs all three, not just the 4.95% state rate. The Illinois tax calculator estimates state income tax on income after deductions, sales tax on a purchase you enter, and a simplified annual property tax from property value and county.
Income tax is max(0, annual income − deductions) × 4.95%. Filing status is collected for context and does not change the flat rate in this planning model. Sales-tax rates used here are Cook 10.25%, DuPage 7.75%, Lake 8.00%, and 7.25% for other Illinois counties. Property-tax rates are planning averages: Cook 2.10%, DuPage 1.90%, Lake 2.20%, and 2.00% elsewhere, applied to the property value you enter rather than to an equalized assessed value formula.
A $100,000 Illinois income with no deductions produces $4,950 of state income tax. A $75,000 income, $1,000 purchase, and $250,000 home in the default other-county rates adds $3,712.50 income tax, $72.50 sales tax, and $5,000 property tax. Moving the same $300,000 home and $1,000 purchase to Cook County raises the sales and property legs even if income tax is unchanged.
Actual Illinois tax depends on standard exemption amounts, retirement-income subtractions, local-option sales districts, homestead exemptions, and township assessment practices. The combined total is a planning stack, not an IL-1040 or a tax bill. Confirm current IDOR rates, local home-rule sales taxes, and the assessor’s equalized assessed value before filing or bidding on a house.
Use the Illinois tax calculator as a relocation and budget worksheet rather than a filing engine. If you are comparing a Cook County condo with a DuPage house, change county, property value, and a representative purchase basket while holding income still so the local tax gap is isolated. If you are modeling a raise, change income and deductions only. Always replace the planning property rate with the latest tax bill when the decision is a purchase, because millage and exemptions swamp a statewide average.
Illinois Tax Examples
These estimates use the 4.95% flat income tax and the county sales and property rates in the calculator.
| Inputs | Illinois income tax | Notes |
|---|---|---|
| $100,000 income, $0 deductions, other Illinois county | $4,950.00 | Flat 4.95% of taxable income with no sales or property amounts entered. |
| $75,000 income, $1,000 purchase, $250,000 property, other county | $3,712.50 | Sales tax is $72.50 and property tax is $5,000.00 at the other-county rates. |
| $90,000 income, $1,000 purchase, $300,000 property, Cook County | $4,455.00 | Cook rates produce $102.50 sales tax and $6,300.00 property tax on those amounts. |
How to Estimate Illinois Taxes
- Enter annual income and any deductions you want subtracted before the 4.95% rate.
- Choose filing status for your records and select Cook, DuPage, Lake, or another county.
- Optionally enter a purchase amount and a property value to estimate sales and property tax.
- Select Calculate Tax to view income, sales, property, and combined totals.
- Compare counties if you are relocating, because sales and property rates change more than the flat income tax.
Illinois Tax Calculadora FAQ
Is Illinois income tax still a flat rate?
This estimate uses a 4.95% flat rate on income after the deductions you enter. It does not model every IDOR subtraction, credit, or pass-through entity tax.
Does filing status change the Illinois income tax?
Not in this planning model. The rate is flat. Filing status remains on the form so you can keep single versus joint facts with the scenario.
Are the sales-tax rates exact for every city?
No. County labels use representative combined rates. Home-rule municipalities and special districts can add tax, so a Chicago restaurant check can differ from the Cook figure shown here.
Is property tax based on market value or assessed value?
The Illinois tax calculator multiplies the property value you enter by a county planning rate. Real bills use assessed value, equalization, exemptions, and local levies.
Does the combined total include federal tax?
No. Combined tax is only the Illinois income, sales, and property estimates. Add federal income tax separately if you need a full burden picture.
