How to Use This Paycheck Calculator Illinois Tool
Enter your gross annual salary, select your pay frequency and filing status. The paycheck calculator Illinois tool applies 2026 federal brackets, Illinois’s flat 4.95 % state tax (after the personal exemption), and FICA automatically.
Since Illinois has no local income tax, the calculator result is your complete take-home. If you contribute to a 401(k) pre-tax, that reduces your federal adjusted gross income. Illinois starts with federal AGI, so a pre-tax 401(k) contribution reduces both your federal and your Illinois tax. Enter your 401(k) percentage in the deductions section to see the combined savings.
Understanding Your Illinois Paycheck
Your Illinois paycheck has three deduction layers: federal income tax, Illinois state income tax, and FICA. There is no county tax, no city tax, and no state disability insurance. The structure is straightforward, though the flat 4.95 % rate with only a modest $2,925 personal exemption means Illinois takes a meaningful bite compared to some lower-rate neighbors.
Here is the breakdown for a $75,000 annual salary (single filer, one personal exemption):
| Deduction | Annual | Biweekly |
|---|---|---|
| Gross pay | $75,000 | $2,885 |
| Federal income tax | $7,670 | $295 |
| Illinois state tax (4.95 %) | $3,568 | $137 |
| Social Security (6.2 %) | $4,650 | $179 |
| Medicare (1.45 %) | $1,088 | $42 |
| Take-home pay | $58,024 | $2,232 |
The Illinois personal exemption of $2,925 reduces your state taxable income from $75,000 to $72,075 before the 4.95 % rate is applied. This saves approximately $145 per year compared to applying the rate to your full salary. The exemption is available for each allowance claimed on Form IL-W-4 and is not available for single filers with federal AGI above $250,000 ($500,000 for married filing jointly).
Illinois Income Tax Rate 2026
Illinois charges a flat 4.95 % income tax on adjusted gross income minus the personal exemption. Unlike progressive-tax states, every Illinois resident pays the same percentage regardless of whether they earn $30,000 or $500,000 (though the exemption vanishes above the AGI thresholds noted above).
The calculation for $75,000 (single, one exemption) is direct:
- Adjusted gross income: $75,000
- Illinois personal exemption: $2,925
- Taxable income: $72,075
- State tax: $72,075 × 4.95 % = $3,568
Illinois does not have a state standard deduction. The personal exemption is the only reduction available at the state level. Your federal AGI flows into the state calculation, reduced only by $2,925 per exemption claimed. For married filing jointly with both spouses claiming an exemption, the reduction is $5,850 (2 × $2,925). The 2026 Booklet IL-700-T confirms both the rate and the exemption for employer withholding. The automated payroll formula is: tax = 0.0495 × (wages − (Line 1 allowances × $2,925 + Line 2 allowances × $1,000)) ÷ pay periods.
This structure comes from the Illinois Constitution, which mandates a flat-rate income tax. In 2020, voters rejected a proposed constitutional amendment (the “Fair Tax” referendum) that would have allowed progressive brackets. The measure failed approximately 53 % to 47 % (certified results), keeping the flat rate in place for the foreseeable future. Any future attempt to introduce graduated rates would require another constitutional amendment and voter approval.
The current 4.95 % rate has been in effect since July 2017 (increased from 3.75 %). The personal exemption for TY 2026 increased to $2,925, up from $2,850 in TY 2025, per IDOR Bulletin FY 2026-15. The Illinois Department of Revenue publishes the rate schedule.
Federal Tax Brackets 2026
The IRS applies federal income tax identically in every state. For tax year 2026, the brackets reflect the inflation adjustments under Revenue Procedure 2025-32, incorporating changes made permanent by the One, Big, Beautiful Bill Act (Public Law 119-21), signed July 4, 2025. On $75,000 (single filer), subtract the standard deduction first: $75,000 − $16,100 = $58,900 taxable income. Then apply each bracket:
| Bracket | Taxable range | Tax |
|---|---|---|
| 10 % | $0 – $12,400 | $1,240 |
| 12 % | $12,400 – $50,400 | $4,560 |
| 22 % | $50,400 – $58,900 | $1,870 |
| Total federal | $7,670 |
Your effective federal rate is 10.2 %. Combined with Illinois’s effective state rate of 4.8 % (after the exemption), your total income tax burden before FICA is 15.0 %. Add the employee FICA rate of 7.65 % and the grand total is approximately 22.6 %. The federal standard deduction of $16,100 applies only on the federal side; Illinois does not use it for state purposes.
FICA: Social Security and Medicare
FICA deductions are the same in every state.
Social Security is withheld at 6.2 % on earnings up to $184,500 (the 2026 wage base per the Social Security Administration). On $75,000 that comes to $4,650. Medicare is withheld at 1.45 % on all earnings, plus a 0.9 % Additional Medicare Tax on wages above $200,000 for single filers ($250,000 for married filing jointly). On $75,000 that comes to $1,088. The total FICA is $5,738 per year, or $221 per biweekly paycheck.
Your employer matches the Social Security and Medicare portions. Once your wages pass $184,500, Social Security withholding stops and late-year paychecks increase. For Illinois residents earning under $100,000, the state tax ($3,568 on $75k) is actually smaller than the total FICA contribution ($5,738), which means federal payroll policy affects your net pay more than the state rate.
The combined effective rate of approximately 22.6 % on $75,000 leaves 77.4 cents of every dollar as take-home pay. This ratio is nearly identical to Wisconsin (~77.2 %) and meaningfully better than many high-tax coastal states. The real differentiator between Midwest neighbors is not always the total rate but the structure: Illinois gives you predictability with a flat rate and no brackets to cross, while Indiana offers a lower rate overall.
How Illinois Compares to Neighboring States
Take-home pay on $75,000 (single, no pre-tax deductions) across Illinois and its Midwest neighbors. All scenarios share the same federal tax ($7,670) and FICA ($5,738):
| State | State tax | Take-home (annual) | Monthly diff vs IL |
|---|---|---|---|
| Illinois | $3,568 (flat 4.95 %) | $58,024 | — |
| Indiana | ~$2,183 (flat 2.95 %) | ~$59,409 | IN saves ~$115/mo |
| Wisconsin | ~$3,667 (progressive, top 7.65 %) | ~$57,925 | IL saves ~$8/mo |
Indiana’s lower flat rate saves approximately $115 per month over Illinois on state tax alone. However, all 92 Indiana counties levy a local income tax ranging from 0.50 % to 3.00 % (IN DOR Departmental Notice #1, effective Jan. 1, 2026), which can reduce or eliminate that advantage. For example, Lake County, Indiana (common for Chicago metro commuters) charges a 1.50 % county tax, adding approximately $1,110 to the annual tax burden and reducing the monthly state-plus-county advantage to roughly $23.
Wisconsin’s progressive system produces a higher effective state rate than Illinois at $75,000. Wisconsin’s standard deduction phases out entirely for single filers earning $73,630 or more, and the four withholding brackets (3.54 %, 4.65 %, 5.30 %, 7.65 %) yield a total of approximately $3,667 at this income level. Earners below $50,000 generally benefit from Wisconsin’s deduction and lower bottom brackets, but middle-income earners near $75,000 may find Illinois slightly cheaper.
The Illinois-Indiana border is one of the most tax-relevant state lines in the country. Workers in the Chicago metro who live in Indiana (common in the Lake County and Hammond area) can save over $1,300 per year in state tax on $75,000. Indiana’s county tax adds back a substantial portion: at the Lake County rate of 1.50 %, the net state-plus-county advantage drops to roughly $275 per year. In lower-tax Indiana counties like Porter (0.50 %), the annual net advantage remains closer to $1,000.
FAQ
What percent is taken out of a paycheck in Illinois?
Federal tax (10 %–37 % marginal), Illinois state tax (flat 4.95 % on income minus the $2,925 personal exemption), Social Security (6.2 %), and Medicare (1.45 %). No local income tax applies. On $75,000, the combined effective rate is approximately 22.6 %.
Does Illinois have local income tax?
No. Illinois does not allow cities or counties to levy income tax. Chicago residents pay the same state rate as downstate residents. However, Illinois has a relatively high combined sales tax: 6.25 % at the state level, plus local additions up to 4.75 %, bringing some areas above 10 %.
How much is $75,000 after taxes in Illinois?
Approximately $58,024 per year or $2,232 biweekly (single filer, one personal exemption, no pre-tax deductions). Use the paycheck calculator Illinois tool above to see your exact breakdown.
How much is $50,000 after taxes in Illinois?
On $50,000 (single): federal tax ~$3,820, IL state tax ~$2,330, FICA $3,825. Take-home approximately $40,025 per year or $1,540 biweekly.
How much is $100,000 after taxes in Illinois?

Does Illinois have a standard deduction?
No. Illinois does not offer a state standard deduction. However, it does provide a personal exemption of $2,925 per filer for tax year 2026 ($2,850 for TY 2025). This exemption reduces your Illinois taxable income before the 4.95 % rate is applied. It is not available for taxpayers with federal AGI above $250,000 (single) or $500,000 (married filing jointly).
Why can’t Illinois adopt progressive tax brackets?
The Illinois Constitution requires a flat-rate income tax. A 2020 ballot referendum proposed amending the constitution to allow graduated rates, but voters rejected it approximately 53 % to 47 %. Any future attempt requires another constitutional amendment and statewide voter approval. Until then, the flat 4.95 % rate is locked in.
Is overtime taxed at a higher rate in Illinois?
No. Illinois’s flat 4.95 % applies to all income equally. Federal brackets apply the same marginal rates to overtime as to regular pay. Your employer may temporarily withhold at a higher rate on overtime paychecks (since the annualized income appears higher), but the correct amount is reconciled at filing.
How does Illinois compare to states with no income tax?
A $75,000 earner in Illinois pays $3,568 in state tax versus $0 in no-tax states like Florida or Texas. That is roughly $297 per month. However, Illinois has significantly higher property taxes (approximately 2.07 % effective rate per the Tax Foundation, second-highest in the nation) compared to Texas (~1.60 %). The net financial comparison depends heavily on housing costs, local sales tax rates, and salary levels.
