Illinois paycheck calculator
Illinois paycheck calculator for 2026. See your real take-home pay for 2026. Enter your salary, filing status and state, and this works out federal income tax, Social Security and Medicare (FICA), and state income tax, then shows what actually lands in your account. Your paycheck is built in layers: the federal government taxes your income above the standard deduction using graduated brackets, FICA takes a fixed percentage for Social Security and Medicare, and your state adds its own income tax, or none at all. Because each layer follows different rules, two people on the same salary in different states can take home noticeably different amounts. Use this to check a job offer across state lines, plan around a raise, or understand why your net pay sits well below your gross.
How Illinois tax affects your pay
Illinois taxes income at a single flat rate set in its constitution, so everyone pays the same percentage regardless of income; a 2020 ballot measure to switch to graduated rates was rejected. High property and sales taxes do more of the revenue work instead.
Illinois taxes personal income at a single flat rate of 4.95%. The same rate applies whether you earn a modest wage or a high salary, which makes the state portion of your paycheck straightforward to estimate.
Flat 4.95%. No standard deduction; Illinois uses a per-person personal exemption allowance instead. State sales tax 6.25%.
This estimate combines federal income tax, FICA and Illinois state income tax. It excludes city and county income taxes, pre-tax deductions such as 401(k) contributions and health premiums, and tax credits, all of which can change your real take-home pay.

This is an estimate for general guidance, not financial or tax advice. 2026 federal and FICA figures. Federal + FICA + state income tax only; excludes local taxes, pre-tax deductions and credits. State married-jointly figures are an approximation: the state single standard deduction and bracket thresholds are doubled, which matches conforming states but may differ where a state sets its own joint schedule.
