Each bar starts where the previous one ended. What is left at the bottom is your paycheck.
| Line | Per paycheck | Per year |
|---|---|---|

| Take-home pay | $2,232 | $58,025 |
Withholding in real life follows the IRS and Illinois withholding tables paycheck by paycheck, so an individual check can differ by a few dollars from this annualised estimate; the year-end totals are what the tables aim at.
| Frequency | Take-home per check | Gross per check |
|---|---|---|
| Weekly (52×/yr) | $1,116 | $1,442 |
| Biweekly (26×/yr) | $2,232 | $2,885 |
| Semimonthly (24×/yr) | $2,418 | $3,125 |
| Monthly (12×/yr) | $4,835 | $6,250 |
| Salary | Gross per check | Take-home per check | Take-home per year |
|---|---|---|---|
| $50,000 | $1,923 | $1,539 | $40,025 |

The state-specific rules behind the numbers above — the things a generic calculator gets wrong about Illinois.
Illinois has no standard deduction — a genuine outlier. Instead, every filer gets a personal exemption of $2,925 per person subtracted from base income. The catch: the exemption cannot be claimed at all if federal AGI exceeds $250,000 for a single filer ($500,000 for joint filers), so high earners are taxed on base income from the first dollar.

Under 35 ILCS 5/203, Illinois subtracts virtually all qualified retirement income from federal AGI: Social Security and railroad retirement benefits, public and private pensions, 401(k), 403(b) and 457(b) withdrawals, traditional and Roth IRA distributions, and even amounts converted from a traditional IRA to a Roth IRA. A retiree whose income comes only from those sources pays no Illinois income tax at all, even though wages are taxed at 4.95%. Non-qualified commercial annuities bought outside a plan are a notable exception and stay taxable.

Illinois' flat rate is not just a policy choice: the state constitution requires an income tax to be non-graduated. A 2020 referendum to allow graduated rates failed, so 4.95% applies to every dollar of base income whether you earn $30,000 or $3 million.

4.95% flat on Illinois base income — the highest flat rate in the country. On a $75,000 salary for a single filer, this page's calculator puts Illinois state tax at $3,568, with net pay of $58,025 after federal tax of $7,670 and FICA of $5,738 (total tax $16,975).
Illinois has no standard deduction at all. Instead you get a personal exemption of $2,925 per person, which reduces base income before the 4.95% rate applies.
In almost every case, no. Illinois subtracts virtually all qualified retirement income — Social Security, pensions, 401(k) and 403(b) withdrawals, traditional and Roth IRA distributions (including Roth conversions) and government retirement pay — so a retiree living only on those sources owes no Illinois income tax.
No — you lose the exemption entirely if your federal AGI exceeds $250,000 as a single filer ($500,000 jointly). Below those limits the full $2,925 per-person exemption applies.
Illinois' constitution requires any income tax to be levied at a single non-graduated rate. Voters rejected a constitutional amendment for graduated rates in 2020, so the flat 4.95% structure remains locked in unless the constitution changes.
No. No Illinois city or county levies a local income tax — Chicago, Springfield and Rockford workers pay only the state's 4.95%. Local burdens in Illinois come mainly through sales and property taxes instead.

On a $75,000 salary paid bi-weekly in Illinois (single filer, 2026): gross per paycheck is $2,884.62, federal withholding $295.00, Social Security and Medicare $220.67, Illinois tax $137.22, leaving take-home of $2,231.72 per paycheck — $58,024.79 a year.
The calculator annualises your pay, works out the year’s federal tax (2026 brackets and standard deduction, IRS Rev. Proc. 2025-32), Social Security at 6.2% to the $184,500 wage base, Medicare at 1.45% plus the 0.9% additional tax over the threshold, and Illinois tax on the state’s own 2026 schedule, then divides by your pay frequency. Pre-tax deductions reduce the taxable amounts before the annual figure is split.
