Your Illinois take-home pay is reduced by the state's flat 4.95% income tax in addition to federal income tax and FICA. A family earning $100,000 in Illinois takes home roughly $70,000-73,000 — about $5,000-8,000 less than the same family in neighboring Indiana (3.05% flat) and $6,000-8,000 less than in no-tax states. Illinois has no local income taxes, no state disability insurance (SDI), and no paid family leave tax, keeping the paycheck math simpler than states like California or New York. Our calculator provides a precise paycheck breakdown showing your bi-weekly or monthly take-home after the IL flat tax, federal brackets, FICA, and voluntary deductions.

Frequently Asked Questions
How much take-home pay on $100K in Illinois?
A $100,000 salary in Illinois yields approximately $70,000-73,000 take-home (single filer, standard deduction). That's roughly $2,700-2,800 per bi-weekly paycheck. The IL flat tax takes $4,821 (after $2,625 personal exemption), federal tax takes ~$12,000-14,000, and FICA takes $7,650. Compare: same salary in Indiana yields ~$73,000-75,500 take-home.
What deductions come out of an Illinois paycheck?
Illinois paychecks show: Illinois state income tax (4.95% flat rate on income above personal exemption), federal income tax (based on W-4 and brackets), Social Security (6.2% up to $168,600), Medicare (1.45%, plus 0.9% additional over $200K), and voluntary deductions (401k, health insurance, HSA). No local income tax, no SDI, no paid family leave tax.
Does the Illinois flat tax help or hurt high earners?
The flat 4.95% rate benefits high earners compared to progressive-rate states. A $500,000 earner in Illinois pays $24,600 in state tax. The same earner in California pays ~$50,000+ (13.3% top rate), New York ~$40,000+ (10.9%), or New Jersey ~$40,000+ (10.75%). For incomes under ~$50,000, Illinois's rate is higher than what most progressive states charge at that level.
Does Illinois have local income taxes?
No. Illinois does not allow municipalities or counties to impose local income taxes. The 4.95% state flat tax is the only income tax deducted from your paycheck. This contrasts with Ohio (many cities levy 1-3% local tax), Pennsylvania (local earned income taxes up to 3.07%), and New York City (3.078-3.876% city tax on top of state tax).
How does Illinois take-home compare for remote workers?
If you live in Illinois and work remotely for an out-of-state employer, you pay Illinois's 4.95% flat tax on all income. If you live in another state and work remotely for an Illinois employer, you generally pay tax to your home state, not Illinois. Illinois has reciprocal tax agreements with Iowa, Kentucky, Michigan, and Wisconsin — residents of those states working in Illinois (and vice versa) pay tax only to their home state.
