Illinois Paycheck Calculator Hourly & Fixed Salary
Calculate your exact take-home pay in Illinois — including federal income tax, Illinois flat state tax, FICA (Social Security & Medicare), and all pre-tax deductions. Free salary and hourly paycheck estimator for 2026.
What Is This Tool?
This Illinois Paycheck Calculator helps employees, freelancers, and HR professionals instantly estimate their net take-home pay after all federal and state deductions. Whether you’re salaried or hourly, paid weekly or bi-weekly, working in Chicago or downstate Illinois — this tool breaks down every dollar that leaves your paycheck before it reaches your bank account.
Illinois has one of the simplest state tax structures in the country: a single flat income tax rate that applies to everyone equally, regardless of how much they earn. But when you stack federal income tax, FICA contributions, and pre-tax deductions on top of that, your gross paycheck and your actual take-home pay can look very different.

How Your Illinois Paycheck Is Calculated
Every Illinois paycheck goes through the same sequence of deductions. Here is exactly what happens, in order:
Step 1 — Start with Gross Pay Gross pay is your total earnings before any deductions. For salaried workers, this is your annual salary divided by the number of pay periods. For hourly workers, it is your hourly rate multiplied by hours worked.
Step 2 — Subtract Pre-Tax Deductions Pre-tax deductions reduce your taxable income before any taxes are calculated. Common ones include 401(k) contributions, 403(b) contributions, Health Savings Account (HSA) contributions, Flexible Spending Account (FSA) contributions, and employer-sponsored health/dental/vision insurance premiums.
Step 3 — Calculate Federal Income Tax Federal income tax is progressive — you pay a higher rate only on the income within each bracket, not on your entire income. Your filing status (Single, Married Filing Jointly, Married Filing Separately, or Head of Household) and your W-4 elections determine exactly how much is withheld.
Step 4 — Calculate Illinois State Income Tax Illinois taxes all income at a single flat rate of 4.95% — no brackets, no tiers. Every worker in Illinois pays the same percentage regardless of whether they earn $25,000 or $250,000.
Step 5 — Subtract FICA Taxes Social Security and Medicare taxes (together called FICA) are withheld from every paycheck at fixed rates.
Step 6 — Subtract Post-Tax Deductions Post-tax deductions come out after taxes are calculated. These include Roth 401(k) contributions, union dues, wage garnishments, child support orders, and voluntary after-tax benefit elections.
Step 7 — Result: Your Net (Take-Home) Pay What remains is your net pay — the actual amount deposited in your bank account or written on your check.
Illinois State Income Tax — The Flat Rate Explained
Current Rate: 4.95% Applies To: All taxable income Personal Exemption: $2,925 per filer (2026)
Illinois is one of a small number of states that uses a constitutionally mandated flat income tax. Article IX of the Illinois Constitution requires that income be taxed at a uniform rate, meaning the state cannot legally impose higher tax rates on higher earners without a constitutional amendment.
In November 2020, Illinois voters were asked to approve a referendum that would have replaced the flat tax with a graduated (progressive) system. The referendum was rejected by voters, cementing the flat rate structure for the foreseeable future.
What the Flat Tax Means for You
| Annual Income | Illinois State Tax Withheld (4.95%) |
|---|---|
| $30,000 | $1,485 |
| $50,000 | $2,475 |
| $75,000 | $3,713 |
| $100,000 | $4,950 |
| $150,000 | $7,425 |
| $200,000 | $9,900 |
Note: Actual withholding may vary slightly based on personal exemption claims and pay frequency.
No Local Income Tax in Illinois
Unlike states such as Pennsylvania, Ohio, or Maryland — Illinois cities and counties, including Chicago, do NOT impose a separate local income tax on wages. No matter where in Illinois you work, you pay only the 4.95% state rate on top of federal.
Federal Income Tax Brackets (2026)
Federal income tax uses a progressive bracket system. You pay each rate only on the income that falls within that bracket — not on your entire income.
Single Filers — 2026 Federal Tax Brackets
| Taxable Income | Federal Tax Rate |
|---|---|
| Up to $11,925 | 10% |
| $11,926 – $48,475 | 12% |
| $48,476 – $103,350 | 22% |
| $103,351 – $197,300 | 24% |
| $197,301 – $250,525 | 32% |
| $250,526 – $626,350 | 35% |
| Over $626,350 | 37% |
Married Filing Jointly — 2026 Federal Tax Brackets
| Taxable Income | Federal Tax Rate |
|---|---|
| Up to $23,850 | 10% |
| $23,851 – $96,950 | 12% |
| $96,951 – $206,700 | 22% |
| $206,701 – $394,600 | 24% |
| $394,601 – $501,050 | 32% |
| $501,051 – $751,600 | 35% |
| Over $751,600 | 37% |
2026 Federal Standard Deductions (Post-OBBB Act)
| Filing Status | Standard Deduction |
|---|---|
| Single | $16,100 |
| Married Filing Jointly | $32,200 |
| Head of Household | $24,150 |
Standard deductions were increased under the One, Big, Beautiful Bill (OBBB Act) signed in 2025, effective for the 2026 tax year. This means slightly more take-home pay for most filers compared to 2025.
FICA Taxes — Social Security & Medicare (2026)
FICA stands for the Federal Insurance Contributions Act. These taxes fund the Social Security retirement/disability program and the Medicare health insurance program for seniors. They are mandatory for nearly all workers.
Employee FICA Rates (2026)
| Tax | Rate | Wage Cap |
|---|---|---|
| Social Security | 6.2% | First $184,500 of wages |
| Medicare | 1.45% | No cap — applies to all wages |
| Additional Medicare | 0.9% | Wages above $200,000 (single) / $250,000 (MFJ) |
| Total FICA (most workers) | 7.65% | — |
Your employer matches your Social Security and Medicare contributions dollar-for-dollar, meaning the true cost to your employer is 15.3% of your wages — but the employee only sees 7.65% on their paycheck.
Social Security Wage Base Increase for 2026
The Social Security wage base rose to $184,500 in 2026 (up from $168,600 in 2025). This means high earners will pay Social Security tax on a slightly larger portion of their income. Once you hit $184,500 in cumulative earnings for the year, Social Security withholding stops for the remainder of that calendar year.
Why Does Illinois Have No State Disability Insurance (SDI)?
Many states — like California, New York, and New Jersey — deduct a separate state disability insurance tax from employee paychecks. Illinois does not. There is no SDI program in Illinois, and no employee payroll deduction for it. Employers may offer voluntary private disability insurance, but it is not a state-mandated payroll deduction.
Pre-Tax Deductions That Reduce Your Taxable Income
One of the most effective ways to increase take-home pay legally is through pre-tax deductions — contributions made before taxes are calculated. These reduce both your federal taxable income and your Illinois state taxable income.
Common Pre-Tax Deductions
401(k) / 403(b) Retirement Contributions Traditional (not Roth) contributions to employer-sponsored retirement plans reduce your taxable wages dollar for dollar. For 2026, employees can contribute up to $23,500 per year ($31,000 if age 50 or older, due to catch-up contribution rules).
Health Insurance Premiums If your employer deducts health, dental, or vision insurance premiums from your paycheck before taxes under a Section 125 Cafeteria Plan, those amounts are not subject to federal or Illinois state income tax, or FICA taxes.
Health Savings Account (HSA) Contributions to an HSA are fully pre-tax at the federal level and reduce your taxable income. For 2026, the HSA contribution limit is $4,300 for individuals and $8,550 for families.
Flexible Spending Account (FSA) FSA contributions for healthcare or dependent care are pre-tax. The 2026 healthcare FSA limit is $3,200.
Dependent Care FSA Up to $5,000 per household per year can be set aside pre-tax for qualifying dependent care expenses (childcare, adult day care).
Illinois Minimum Wage — 2026
Understanding where your gross pay starts is the foundation of any paycheck calculation.
| Location | Minimum Wage (2026) |
|---|---|
| Illinois Statewide | $15.00 per hour |
| Chicago (large employers, 4+ employees) | $16.60 per hour (through June 30, 2026) |
| Chicago (large employers) | $16.20 per hour (from July 1, 2026) |
| Cook County (unincorporated) | $14.05 per hour |
| Youth Workers (under 18, under 650 hrs/yr) | $13.00 per hour |
Chicago’s minimum wage adjusts annually on July 1 based on the Consumer Price Index (CPI). Illinois statewide minimum wage does not automatically adjust for inflation — future increases require new legislation.
Pay Frequency and How It Affects Your Withholding
The same annual salary results in different per-paycheck withholding amounts depending on how often you are paid. Illinois employers typically use one of these frequencies:
| Pay Frequency | Pay Periods Per Year | Example: $60,000/yr Gross Per Check |
|---|---|---|
| Weekly | 52 | $1,154 |
| Bi-Weekly | 26 | $2,308 |
| Semi-Monthly | 24 | $2,500 |
| Monthly | 12 | $5,000 |
Illinois law requires most employers to pay at least semi-monthly (twice per month). Weekly and bi-weekly are also common. Monthly pay is allowed but less typical for hourly workers.
Illinois Tax Reciprocity Agreements
Illinois has reciprocal tax agreements with four neighboring states:
- Iowa
- Kentucky
- Michigan
- Wisconsin
If you live in one of these states but work in Illinois, your Illinois wages are exempt from Illinois state income tax withholding. You only pay income tax to your home state. To claim this exemption, you must file Form IL-W-5-NR (Employee’s Statement of Nonresidence in Illinois) with your Illinois employer.
If you live in Illinois but work in one of these states, the reverse applies — you pay Illinois income tax only, not the other state’s income tax.
Unemployment Insurance — What Employers Pay on Your Behalf
While employees do not see a UI deduction on their Illinois paychecks, it is worth understanding: Illinois employers pay State Unemployment Insurance (SUI) tax to the Illinois Department of Employment Security (IDES) on your behalf.
- 2026 Wage Base: $14,250 per employee per year
- 2026 Rate Range: 0.75% – 7.05% (varies by employer experience rating)
- New Employer Rate (2026): 3.35%
This employer-paid tax funds unemployment benefits for workers who lose their jobs through no fault of their own. Employees do not pay SUI in Illinois — it is 100% employer-funded.
Real-World Paycheck Example
Scenario: Single filer, $75,000 annual salary, bi-weekly pay (26 periods), contributes $300/period to 401(k), employer health insurance $150/period, no additional withholding.
| Item | Per Paycheck | Annual |
|---|---|---|
| Gross Pay | $2,884.62 | $75,000 |
| 401(k) Pre-Tax | − $300.00 | − $7,800 |
| Health Insurance Pre-Tax | − $150.00 | − $3,900 |
| Federal Taxable Income | $2,434.62 | $63,300 |
| Federal Income Tax (est.) | − $290.00 | − $7,540 |
| Illinois State Tax (4.95%) | − $120.51 | − $3,133 |
| Social Security (6.2%) | − $178.85 | − $4,650 |
| Medicare (1.45%) | − $41.83 | − $1,088 |
| Estimated Net Take-Home | ~$1,803 | ~$46,889 |
These are estimates. Actual amounts depend on exact W-4 elections, pay dates, and employer benefit plan structures.

Frequently Asked Questions (FAQs)
What is the Illinois state income tax rate?
Illinois uses a flat income tax rate of 4.95% on all taxable income. Every worker pays the same percentage regardless of income level. This rate is fixed in the Illinois Constitution, which prohibits graduated (progressive) income tax rates.
Does Illinois have local income taxes on wages?
No. Illinois does not allow cities or counties to impose local income taxes on wages. Chicago, Evanston, Springfield — none of them add a city income tax on top of the 4.95% state rate. This makes Illinois paycheck calculations simpler than many other states.
How is federal income tax calculated on my Illinois paycheck?
Federal income tax is calculated using progressive tax brackets (10% to 37% for 2026). Your employer uses your W-4 form to determine how much to withhold. The actual amount depends on your filing status, the standard deduction, any dependents you claim, and any additional withholding you request on your W-4.
What is FICA and how much is withheld?
FICA (Federal Insurance Contributions Act) consists of two taxes: Social Security at 6.2% of wages up to $184,500, and Medicare at 1.45% of all wages. Together, most employees see 7.65% withheld for FICA. High earners pay an additional 0.9% Medicare surtax on wages above $200,000.
What does “gross pay” vs “net pay” mean?
Gross pay is your total earnings before any deductions — the number in your employment offer. Net pay (also called take-home pay) is what you actually receive after federal tax, state tax, FICA, and other deductions are subtracted.
How do pre-tax deductions help me?
Pre-tax deductions like 401(k) contributions and health insurance premiums are subtracted from your gross pay before taxes are calculated. This lowers your taxable income, which reduces both your federal tax and Illinois state tax withholding. Contributing $500/month pre-tax saves you roughly $24.75/month in Illinois state tax alone (at 4.95%), plus additional federal tax savings.
What is the W-4 form and why does it matter?
Form W-4 (Employee’s Withholding Certificate) is the IRS form you give your employer when you start a job. It tells your employer how much federal income tax to withhold. The 2020 redesign eliminated allowances and replaced them with direct income/deduction figures. If your withholding is wrong — too little or too much — updating your W-4 is the fix.
What is the Illinois W-4 equivalent?
Illinois has its own withholding certificate: Form IL-W-4 (Employee’s Illinois Withholding Allowance Certificate). It determines how much Illinois income tax your employer withholds. Unlike the federal W-4, it still uses allowances. Each allowance claimed reduces your Illinois withholding.
Is there a state disability insurance (SDI) tax in Illinois?
No. Illinois does not have a state disability insurance program, so there is no SDI deduction from employee paychecks. This is unlike California, New York, New Jersey, and several other states that mandate employee SDI contributions.
Does Illinois have paid family leave (PFL) tax?
No. Illinois does not currently have a mandatory state-run paid family leave program with employee payroll deductions. Some employers offer private PFL policies, but there is no Illinois-mandated payroll deduction for it as of 2026.
What is the minimum wage in Illinois for 2026?
The Illinois statewide minimum wage is $15.00 per hour as of January 1, 2026. Chicago has a higher minimum wage of $16.60/hour (through June 30, 2026), which adjusts to $16.20/hour effective July 1, 2026. Cook County unincorporated areas are at $14.05/hour. Youth workers under 18 (working fewer than 650 hours per year) may be paid $13.00/hour.
I live in Wisconsin but work in Illinois. Do I pay Illinois tax?
No. Illinois has a reciprocal tax agreement with Wisconsin (and also with Iowa, Kentucky, and Michigan). If you live in one of these states and work in Illinois, you are exempt from Illinois state income tax withholding. You must file Form IL-W-5-NR with your Illinois employer to claim this exemption and pay income tax only to your home state.
How much does a $5,000 raise actually add to my paycheck in Illinois?
A $5,000 annual raise means an extra $247.50 in Illinois state tax per year (4.95%), plus additional federal income tax at your marginal rate. If you’re in the 22% federal bracket, you keep roughly $5,000 × (1 − 0.22 − 0.0495 − 0.0765) = approximately $3,270 more per year, or about $126 more per bi-weekly paycheck.
What happens to Social Security withholding once I earn over $184,500?
Once your year-to-date wages exceed $184,500 (the 2026 Social Security wage base), Social Security withholding stops for the rest of the calendar year. Your paychecks in the latter part of the year will be larger. Medicare withholding (1.45%) continues on all wages with no cap.
What is the difference between marginal and effective tax rate?
Your marginal rate is the tax rate on your next dollar earned — the highest bracket you’ve reached. Your effective rate is total tax divided by total income — a lower average. For example, a single filer with $75,000 in Illinois might have a 22% federal marginal rate but only a ~12–13% federal effective rate because most of their income was taxed at lower brackets.
How is overtime pay taxed in Illinois?
Overtime pay (typically 1.5× your regular rate for hours over 40 per week under the FLSA) is taxed the same as regular wages in Illinois. There is no special overtime tax rate. Federal withholding on overtime may appear higher because it can push you into a higher marginal bracket for that pay period, but your annual effective rate remains the same.
Can I use this calculator for self-employment income?
This calculator is optimized for W-2 employees. Self-employed individuals (freelancers, independent contractors, sole proprietors) pay self-employment tax at 15.3% (both employee and employer halves of FICA) plus Illinois income tax at 4.95%, and are responsible for making quarterly estimated tax payments. For self-employment income, also consider consulting a tax professional or using IRS Form 1040-ES.
How often should I update my W-4?
The IRS recommends reviewing your W-4 after any major life change: getting married or divorced, having a child, buying a home, starting a second job, or receiving a large bonus. Also review it at the start of each year when tax rates or standard deductions change.
