Illinois uses a flat income tax. Every dollar of taxable income is taxed at 4.95%. The rate is the same at many income levels.
That means a raise is easier to estimate. Your Illinois state income tax usually rises in a direct way. More taxable income means more tax at the same rate.
Illinois grants a personal exemption of about $2,775 per person. It does not use a general standard deduction. So your taxable income is your pay minus that exemption.
There is no city income tax in Illinois for most workers. That keeps state withholding simple. Your state tax is roughly 4.95% of income after the exemption.
Start with gross pay — what you earn before taxes and deductions. Choose a pay period, subtract pre-tax deductions, then subtract payroll taxes. What is left is your net, take-home pay. The calculator above does all of it live as you type.

Federal income tax (2026 brackets), Illinois income tax, Social Security (6.2%), and Medicare (1.45%) come out.
The remainder is your net pay — shown per paycheck and per year, with an itemized breakdown so nothing is a black box.
Illinois uses a flat 4.95% income tax. It applies after the personal exemption. The flat rate makes Illinois tax easy to predict.
| Taxable income | Illinois rate |
|---|---|
| All taxable income | 4.95% |
Local taxes are simple. Illinois has no local income tax for most workers. So 4.95% flat is the main state tax rule.
Deductions still help. Every pre-tax dollar you contribute can save Illinois tax. It can also save federal tax. For example, a pre-tax 401(k) contribution lowers taxable wages. A health plan premium may do the same.
Federal income tax uses brackets from 10% to 37%. The brackets apply after the federal standard deduction. Only the dollars in each bracket use that rate.
A raise does not tax all your income at the higher rate. It only affects your next dollars. Your earlier income keeps the lower rates.
FICA means the Federal Insurance Contributions Act. FICA taxes are the same in every state. They include Social Security tax and Medicare tax.
Employees pay 6.2% for Social Security tax up to the annual wage base. They also pay 1.45% for Medicare on all wages. High earners may owe additional Medicare tax of 0.9%.
In Illinois, federal tax, FICA, and the flat 4.95% state tax explain most pay gaps. These taxes create the difference between gross pay and take-home pay.
These examples use a single filer and the personal exemption. They assume no dependents. They also assume no pre-tax benefits or extra withholding. Open the calculator to match your exact situation.

Illinois has a moderate flat rate. The gap with a no-tax state may be smaller than expected. The gap with a high-tax state may be larger. A move is not only about taxes — housing, insurance, commuting, and sales tax also matter. The calculator gives a quick first look at the income-tax side of a move.
Illinois has a flat income tax of 4.95% on taxable income. It applies after a personal exemption of about $2,775 per person.
Illinois withholds a flat 4.95% state tax. Federal income tax, Social Security tax, and Medicare tax also come out.
No. Illinois municipalities generally do not levy a separate income tax. So 4.95% flat is the state income tax rule.
That depends on your employer. Common schedules are weekly, biweekly, semi-monthly, and monthly.
It is a close estimate using 2026 federal brackets and recent Illinois rates. Your real withholding depends on your W-4, benefits, and payroll setup.
No. Every calculation runs in your browser. Nothing is uploaded, saved, or sent to a server.
Filing status changes your federal brackets and standard deduction. Single, married filing jointly, and head of household each withhold differently. Your W-4 tells payroll which status to use.
Pre-tax deductions reduce taxable income. A 401(k), HSA, FSA, or pre-tax health premium can lower tax. These choices can also lower your paycheck now.
Dependents and credits matter. A child tax credit can reduce federal withholding. A second job can increase the amount you should withhold.
Your Illinois IL-W-4 choices matter too. The form helps your employer estimate Illinois state income tax. Extra withholding can prevent a surprise tax bill.
Your pay period changes check size, not salary. A $75,000 salary paid biweekly creates 26 checks. The same salary paid semi-monthly creates 24 larger checks.
A paycheck calculator is an estimate. Payroll systems use your forms and plan elections. Small differences are normal.
Bonuses can also look different. Employers often withhold bonus pay at special rates. Commissions and overtime may raise one check more than expected.
Benefits can change the math. Pre-tax deductions usually lower taxable pay. Post-tax deductions lower your net pay after taxes.
Year-to-date wages can matter. Social Security tax stops after the annual wage base. Additional Medicare tax may start after high wages.
If your result looks wrong, check your inputs first. Confirm your gross pay and pay period. Then review filing status, benefits, and extra withholding.
