HOW TO CALCULATE HOURLY TO SALARY IN ILLINOIS

Understanding Illinois salary calculations is straightforward thanks to the state’s flat tax system, making it easier than most states with progressive tax brackets.

Hourly to Salary Calculator Illinois: Basic Formula

The core formula is simple, and Illinois’ flat 4.95% tax makes calculations predictable:

Gross Annual Salary = Hourly Rate × Hours Per Week × Weeks Per Year

For Illinois workers at $25/hour, 40 hours/week, 52 weeks/year: $25 × 40 × 52 = $52,000 gross annual salary

However, Illinois net pay calculation requires subtracting:

• Federal income tax (~12% effective at $52k)
• Illinois state income tax: ($52,000 – $2,925 exemption) × 4.95% = $2,429
• Social Security: $52,000 × 6.2% = $3,224
• Medicare: $52,000 × 1.45% = $754

Net annual pay: ~$37,600 (72% of gross)

In comparison, the same $52,000 salary in Indiana (3.15% flat tax) yields ~$38,400 net pay (74% of gross), a difference of $800 annually or $67 per month, primarily due to Illinois’ higher state tax rate.

Step-by-Step Calculation for Illinois Workers

Step 1: Calculate gross salary Multiply your Illinois hourly rate by hours and weeks worked. Example: $20/hour × 40 hours × 52 weeks = $41,600

Step 2: Calculate Illinois state income tax Illinois uses a flat 4.95% tax on income after personal exemption:

• Taxable income: $41,600 – $2,925 (personal exemption) = $38,675
• Illinois tax: $38,675 × 4.95% = $1,914

Step 3: Calculate federal income tax For single filer earning $41,600 using 2026 federal brackets:

• Standard deduction: $16,100 (2026)
• Taxable income: $41,600 – $16,100 = $25,500
• First $11,925 at 10% = $1,193
• Remaining $13,575 at 12% = $1,629
• Total federal tax: $2,822

Step 4: Calculate FICA (Social Security + Medicare)

• Social Security: $41,600 × 6.2% = $2,579
• Medicare: $41,600 × 1.45% = $603
• Total FICA: $3,182

Step 5: Calculate Illinois net pay $41,600 – $1,914 (IL) – $2,822 (Fed) – $3,182 (FICA) = $33,682 net pay

Your Illinois take-home pay is 81% of gross at this income level.

Illinois-Specific Calculation Examples

Example 1: $20/hour in Chicago

Gross Calculation:

• Hourly rate: $20.00
• Hours per week: 40
• Weeks per year: 52
• Annual gross salary: $41,600

Illinois Deductions:

• IL state income tax: $1,914 (4.6% effective after exemption)
• Federal income tax: $2,822 (6.8% effective)
• FICA: $3,182 (7.65%)
• Total deductions: $7,918 (19.0%)

Net Pay:

• Annual net: $33,682
• Monthly net: $2,807
• Bi-weekly net: $1,296
• Take-home percentage: 81%

Chicago Context: At $20/hour in Chicago, you’re earning above both Illinois minimum wage ($15.00) and Chicago minimum wage ($16.60 for employers with 4+ employees). However, Chicago’s living wage for single adults is estimated at $19-21/hour. Chicago median 1-bedroom rent is $1,600-$1,900/month, consuming 57-68% of your take-home pay, making this salary challenging for independent living in the city proper but more manageable in Chicago suburbs.

Example 2: $30/hour in Suburban Chicago (DuPage County)

Gross Calculation:

• Hourly rate: $30.00
• Hours per week: 40
• Weeks per year: 52
• Annual gross salary: $62,400

Illinois Deductions:

• IL state income tax: $2,944 (4.7% effective after exemption)
• Federal income tax: $6,336 (10.2% effective)
• FICA: $4,774 (7.65%)
• Total deductions: $14,054 (22.5%)

Net Pay:

• Annual net: $48,346
• Monthly net: $4,029
• Bi-weekly net: $1,859
• Take-home percentage: 77.5%

DuPage County Context: At $30/hour in suburban Chicago counties (DuPage, Lake, Kane, Will), you’re earning a solid middle-class income. Suburban Chicago median 1-bedroom rent ranges from $1,200-$1,500/month, consuming 30-37% of your take-home pay—a comfortable ratio. Property taxes in Illinois suburbs are high (often $5,000-$10,000+ annually for homeowners), but this doesn’t directly affect renters.

Example 3: $15/hour at Illinois Minimum Wage

Gross Calculation:

• Hourly rate: $15.00 (Illinois minimum wage 2026)
• Hours per week: 40
• Weeks per year: 52
• Annual gross salary: $31,200

Illinois Deductions:

• IL state income tax: $1,400 (4.5% effective after exemption)
• Federal income tax: $1,812 (5.8% effective – lower bracket)
• FICA: $2,387 (7.65%)
• Total deductions: $5,599 (17.9%)

Net Pay:

• Annual net: $25,601
• Monthly net: $2,133
• Bi-weekly net: $985
• Take-home percentage: 82.1%

Illinois Minimum Wage Context: At Illinois’ $15.00 minimum wage, workers face lower tax rates due to federal standard deduction reducing taxable income and the personal exemption reducing Illinois tax. However, $15/hour is challenging even in lower-cost downstate Illinois cities. Many minimum wage workers qualify for federal EITC (Earned Income Tax Credit) and Illinois state credits, potentially adding $2,000-$6,000 in refunds at tax time.

Example 4: $25/hour with Regular Overtime in Illinois

Gross Calculation:

• Regular hourly rate: $25.00
• Regular hours: 40 per week
• Overtime hours: 5 per week (at time-and-a-half)
• Overtime rate: $37.50

Weekly Breakdown:

• Regular pay: $25 × 40 = $1,000
• Overtime pay: $37.50 × 5 = $187.50
• Total weekly: $1,187.50
• Annual gross: $61,750

Illinois Deductions:

• IL state income tax: $2,912 (4.7% effective)
• Federal income tax: $6,234 (10.1% effective)
• FICA: $4,724 (7.65%)
• Total deductions: $13,870 (22.5%)

Net Pay:

• Annual net: $47,880
• Monthly net: $3,990
• Bi-weekly net: $1,842
• Take-home percentage: 77.5%

Illinois Overtime Impact: The 5 hours of weekly overtime adds $9,750 to your annual gross income (regular 40 hours = $52,000). Illinois’ flat tax and federal taxes mean you keep about 76% of that overtime income after taxes, netting an additional $7,410 annually. Illinois follows standard federal overtime rules (after 40 hours/week) with time-and-a-half, no daily overtime or double-time provisions like California.

REVERSE CALCULATOR – ILLINOIS ANNUAL SALARY TO HOURLY RATE

Converting Illinois annual salaries to hourly rates helps you compare salaried positions with hourly jobs and understand your true per-hour earnings after Illinois’ flat tax.

How to Convert Illinois Salary to Hourly Wage

The reverse calculation divides annual salary by total hours worked, but understanding Illinois take-home requires factoring in the state’s 4.95% flat tax plus federal taxes.

Basic Formula: Hourly Rate = Annual Salary ÷ 2,080 hours (40 hours × 52 weeks)

Illinois Take-Home Hourly Rate: Effective Hourly Rate = (Annual Salary – Illinois tax – Federal tax – FICA) ÷ 2,080

This “effective hourly rate” shows what you actually earn per hour after Illinois’ combined tax burden, which ranges from 18% to 30% depending on your income level.

Salary to Hourly Formula for Illinois

Step 1: Divide annual salary by 2,080 This gives you gross hourly rate before any Illinois or federal deductions.

Step 2: Calculate Illinois flat tax impact Illinois tax is always 4.95% of taxable income (after $2,925 personal exemption):

• Approximate: ~4.5-4.8% of gross income for most earners

Step 3: Calculate federal tax impact Estimate 10-20% of annual salary for federal income tax (varies by bracket).

Step 4: Calculate FICA Always 7.65% (6.2% Social Security + 1.45% Medicare) up to Social Security wage cap.

Step 5: Determine effective hourly rate Subtract all taxes from annual salary, then divide by 2,080.

Example: $60,000 Illinois salary:

• Gross hourly: $60,000 ÷ 2,080 = $28.85/hour
• Illinois tax (~$2,826): -$1.36/hour
• Federal tax (~$5,834): -$2.80/hour
• FICA ($4,590): -$2.21/hour
• Effective hourly: $22.48/hour

Your Illinois take-home is $22.48/hour on a $60,000 salary, which is 78% of your gross hourly rate.

Illinois Salary Conversion Examples

Example: $50,000 salary to hourly in Illinois

Gross Calculation:

• Annual salary: $50,000
• Standard hours: 2,080 per year
• Gross hourly rate: $24.04/hour

Illinois Tax Impact:

• IL state income tax: $2,330 (4.66% effective after exemption)
• Federal income tax: $4,034 (8.1% effective)
• FICA: $3,825 (7.65%)
• Total annual deductions: $10,189

Net Illinois Earnings:

• Annual net: $39,811
• Effective hourly rate: $19.14/hour
• Take-home percentage: 79.6%

Illinois vs. Indiana Comparison: The same $50,000 salary in Indiana (3.15% flat tax):

• Annual net: ~$40,600
• Effective hourly: $19.52/hour
• Difference: $0.38/hour more in Indiana (about $789 annually)

Indiana’s lower flat tax (3.15% vs Illinois’ 4.95%) means Indiana workers keep more despite both states having flat-tax systems.

Example: $75,000 salary to hourly in Illinois

Gross Calculation:

• Annual salary: $75,000
• Standard hours: 2,080 per year
• Gross hourly rate: $36.06/hour

Illinois Tax Impact:

• IL state income tax: $3,568 (4.76% effective after exemption)
• Federal income tax: $9,534 (12.7% effective)
• FICA: $5,738 (7.65%)
• Total annual deductions: $18,840

Net Illinois Earnings:

• Annual net: $56,160
• Effective hourly rate: $27.00/hour
• Take-home percentage: 74.9%

Illinois Middle-Income Reality: At $75,000 in Illinois, you lose 25.1% to taxes compared to ~22% in Indiana or ~24% in Wisconsin. Illinois’ 4.95% flat rate means all income (after personal exemption) is taxed equally regardless of amount, providing tax simplicity but potentially higher burden for middle-income earners compared to states with progressive rates that tax lower income at lower rates.

Example: $100,000 salary to hourly in Illinois

Gross Calculation:

• Annual salary: $100,000
• Standard hours: 2,080 per year
• Gross hourly rate: $48.08/hour

Illinois Tax Impact:

• IL state income tax: $4,805 (4.81% effective after exemption)
• Federal income tax: $16,094 (16.1% effective)
• FICA: $7,650 (7.65%)
• Total annual deductions: $28,549

Net Illinois Earnings:

• Annual net: $71,451
• Effective hourly rate: $34.35/hour
• Take-home percentage: 71.5%

Six-Figure Illinois Reality: At $100,000 in Illinois, you’re still paying the same 4.95% state rate as someone earning $40,000 (after personal exemption). This flat-tax structure means Illinois doesn’t have the progressive state tax burden increase that states like California or Oregon have for six-figure earners. Combined federal-state-FICA burden reaches 28.5%.

High-Earner Illinois Tax Comparison

Annual Take-Home Pay Comparison:

Annual Salary	IL Net Pay	IN Net Pay	WI Net Pay	Annual Difference (IL vs IN)
$50,000	$39,811	$40,600	$40,100	-$789
$75,000	$56,160	$57,800	$56,900	-$1,640
$100,000	$71,451	$73,700	$71,800	-$2,249
$150,000	$101,400	$104,900	$100,900	-$3,500
$200,000	$130,000	$134,400	$128,600	-$4,400

Illinois’ flat 4.95% tax means the state tax burden is consistent across income levels (as percentage of income after exemption), while Indiana’s lower 3.15% flat rate provides savings at all income levels. Wisconsin’s progressive system (3.54-7.65%) results in lower taxes for lower earners but similar burden to Illinois for $100k+ earners.

ILLINOIS TAXES, MINIMUM WAGE, AND YOUR PAYCHECK

Illinois Flat State Income Tax (2026)

Illinois is one of only a few states with a flat income tax rate, making tax calculations simpler than progressive-bracket states.

Illinois Flat Tax Rate: 4.95%

This rate applies to all taxable income after personal exemptions, regardless of how much you earn.

Key Features:

• Same rate for everyone: Someone earning $30,000 and someone earning $300,000 both pay 4.95% on taxable income
• No tax brackets: Unlike most states, Illinois has no progressive brackets
• Simple calculation: Just multiply taxable income by 4.95%
• Rate history: Increased from 3.75% to 4.95% in 2017, remains unchanged since

Illinois Personal Exemption (2026)

Illinois allows a personal exemption that reduces your taxable income before applying the 4.95% rate.

Personal Exemption: $2,925 (2026)

This amount is subtracted from your income before calculating Illinois tax.

Examples of Illinois Tax Calculation:

Earning $40,000 annually:

• Gross income: $40,000
• Personal exemption: -$2,925
• Taxable income: $37,075
• Illinois tax: $37,075 × 4.95% = $1,835
• Effective rate: 4.59% of gross income

Earning $100,000 annually:

• Gross income: $100,000
• Personal exemption: -$2,925
• Taxable income: $97,075
• Illinois tax: $97,075 × 4.95% = $4,805
• Effective rate: 4.81% of gross income

Notice: The effective rate gets closer to 4.95% as income increases, since the $2,925 exemption becomes a smaller percentage of total income.

Illinois Tax Withholding Allowances

Illinois uses Form IL-W-4 for employees to claim withholding allowances, similar to federal W-4 but with different rules.

Illinois Withholding Allowances (2026):

• Basic allowance: $2,925 per allowance claimed
• Self allowance: 1 allowance if no one else can claim you as dependent
• Spouse allowance: 1 allowance if filing jointly
• Dependent allowances: 1 per eligible dependent
• Age/blindness allowances: 1 additional per person 65+ or legally blind

Withholding Calculation: Employers withhold Illinois tax at 4.95% after subtracting allowance amounts from gross wages.

Example: Employee earning $1,000 bi-weekly, claiming 2 allowances:

• Bi-weekly allowance amount: ($2,925 × 2) ÷ 26 pay periods = $225
• Taxable wages: $1,000 – $225 = $775
• Illinois withholding: $775 × 4.95% = $38.36 per paycheck

Why Illinois Has a Flat Tax

Illinois is constitutionally required to have a flat income tax rate.

Constitutional Requirement: The Illinois Constitution (Article IX, Section 3) mandates that income tax rates be “non-graduated” (flat), meaning:

• Cannot have progressive brackets
• Must tax all income at the same rate
• Any change requires constitutional amendment

Failed Progressive Tax Attempt: In November 2020, Illinois voters rejected a constitutional amendment that would have allowed progressive tax rates. The amendment failed 55%-45%, keeping the flat tax in place.

Illinois vs. Progressive Tax States:

State	System	Rates	Impact
Illinois	Flat	4.95% all income	Simple, same rate regardless of income
California	Progressive	1%-13.3% brackets	Lower earners pay less, high earners pay more
Texas	None	0% income tax	No state income tax, higher property/sales tax
Indiana	Flat	3.15% all income	Similar to IL but lower rate
Wisconsin	Progressive	3.54%-7.65%	Lower rates on first income, higher on top

Flat Tax Pros:

• Simple calculation
• Easy to understand
• Predictable withholding
• No bracket creep

Flat Tax Cons:

• Low earners pay same rate as high earners
• No graduated relief for lower incomes
• Can result in higher burden on middle class vs. progressive states

Illinois Minimum Wage (2026)

Illinois reached its target $15.00 minimum wage in 2025 after a multi-year increase schedule.

Current Illinois Minimum Wage (2026):

• General minimum wage: $15.00/hour (workers 18+ years)
• Youth workers (under 18): $13.00/hour (if working less than 650 hours/year)
• Tipped workers: $9.00/hour (60% of minimum, must reach $15 with tips)
• Training wage: $14.50/hour (first 90 days only, for workers 18+, increased to $15.00 in 2026)

No Further Scheduled Increases: Illinois’ minimum wage increase schedule ended with the $15.00 rate on January 1, 2025. There are currently no scheduled future increases without new legislation. Unlike some states, Illinois does not have automatic inflation adjustments for minimum wage.

Illinois Minimum Wage History

Historical Increases (2020-2025):

• January 1, 2020: $9.25/hour → $10.00/hour
• January 1, 2021: $10.00/hour → $11.00/hour
• January 1, 2022: $11.00/hour → $12.00/hour
• January 1, 2023: $12.00/hour → $13.00/hour
• January 1, 2024: $13.00/hour → $14.00/hour
• January 1, 2025: $14.00/hour → $15.00/hour (current)
• January 1, 2026: $15.00/hour (no change)

Public Act 101-0001 (2019): This law, signed by Governor Pritzker, scheduled the gradual increase from $8.25 in 2019 to $15.00 in 2025. The schedule is now complete.

Chicago Minimum Wage (2026)

Chicago has its own higher minimum wage that applies to employers with 4 or more employees.

Chicago Minimum Wage (as of July 1, 2025):

• General workers: $16.60/hour (employers with 4+ employees)
• Tipped workers: $12.62/hour (76% of general minimum)
• Youth workers (under 18): $16.50/hour
• City contract workers: $17.80/hour

Chicago Adjustments: Chicago’s minimum wage increases annually every July 1st based on Consumer Price Index (CPI) or 2.5%, whichever is lower. This ensures the wage keeps pace with inflation but caps increases at 2.5% annually.

July 1, 2026 Projection: Based on the 2.5% cap, Chicago minimum wage is projected to reach approximately $17.00-$17.05/hour by July 1, 2026.

Chicago Tipped Wage Phase-Out: Chicago passed the “One Fair Wage Ordinance” in 2023, gradually eliminating the tipped minimum wage:

• July 1, 2024: Tip credit reduced to 32% of minimum
• July 1, 2025: Tip credit reduced to 24% of minimum (current: $12.62)
• July 1, 2026: Tip credit reduced to 16% of minimum
• July 1, 2027: Tip credit reduced to 8% of minimum
• July 1, 2028: No tip credit – tipped workers receive full minimum wage + tips

This makes Chicago one of the few major cities phasing out the sub-minimum tipped wage entirely.

Cook County Minimum Wage

Cook County (excluding Chicago city limits) follows either Illinois state minimum or its own calculated rate based on CPI, whichever is higher.

Cook County Minimum Wage (2026):

• General minimum: $15.00/hour (currently mirrors Illinois state minimum)
• Tipped workers: $9.00/hour (mirrors Illinois tipped minimum)

Cook County Calculation Rule: The county uses the highest of:

1. Federal minimum wage ($7.25)
2. Illinois minimum wage ($15.00)
3. County calculated rate based on CPI

Exception: If Cook County unemployment rate reaches or exceeds 8.5%, the county-calculated rate is not used.

Currently, Illinois state minimum ($15.00) is the controlling rate for Cook County.

Illinois Overtime Pay Rules

Illinois follows federal Fair Labor Standards Act (FLSA) overtime requirements with few state-specific variations.

Illinois Overtime Rules:

• Overtime required after: 40 hours in a workweek
• Overtime rate: Time-and-a-half (1.5× regular hourly rate)
• No daily overtime: Illinois does not require overtime for long workdays (unlike California’s 8-hour rule)
• No double-time: Illinois has no double-time provisions
• Weekly calculation: Based on 7-day workweek, not bi-weekly or monthly

Overtime Calculation Example:

Scenario: Work 50 hours at $20/hour

• First 40 hours: $20 × 40 = $800 (regular time)
• Next 10 hours: $30 × 10 = $300 (overtime)
• Total weekly pay: $1,100

Illinois Overtime Exemptions

Many Illinois workers are exempt from overtime requirements under federal FLSA rules.

Common FLSA Exemptions (apply in Illinois):

• Executive employees: Manage 2+ employees, have hiring/firing authority
• Administrative employees: Office work requiring discretion/judgment on significant matters
• Professional employees: Work requiring advanced knowledge/education
• Computer professionals: Earning at least $35.47/hour (federal 2024 threshold)
• Outside sales employees: Primary duty is making sales outside employer’s place of business

Salary Threshold for Exemption: To qualify for executive, administrative, or professional exemptions, employees must earn at least:

• $684/week ($35,568 annually) – Federal minimum (applies in Illinois)

Important: Illinois does not have a higher state-specific salary threshold like California or New York. Federal thresholds apply.

Common Misclassifications:

• Paying salary but employee doesn’t meet duties test
• Classifying as “manager” but employee primarily does non-management work
• Computer workers earning under $35.47/hour (or salary threshold)
• Inside sales employees (outside sales exemption doesn’t apply)

Illinois vs. Neighboring States Tax Comparison

Annual Take-Home Pay Comparison at $60,000 Salary:

State	State Tax Rate	State Tax Amount	Total Deductions	Net Take-Home	vs Illinois
Illinois	4.95% flat	$2,826	$13,250	$46,750	Baseline
Indiana	3.15% flat	$1,890	$12,314	$47,686	+$936 (+2.0%)
Wisconsin	4.41-6.27% progressive	$2,900	$13,324	$46,676	-$74 (-0.2%)
Iowa	4.4-5.7% progressive	$2,640	$13,064	$46,936	+$186 (+0.4%)
Missouri	2-4.95% progressive	$2,400	$12,824	$47,176	+$426 (+0.9%)

Key Takeaways:

• Indiana’s lower flat tax (3.15%) provides clear advantage at all income levels
• Wisconsin’s progressive system results in similar burden to Illinois for middle incomes
• Missouri’s progressive rates favor lower/middle earners
• Illinois’ 4.95% flat rate is middle-of-the-pack among Midwest states

High-Income Comparison ($150,000 salary):

State	State Tax	Net Take-Home	vs Illinois
Illinois	$7,281 (4.95%)	$106,000	Baseline
Indiana	$4,725 (3.15%)	$109,200	+$3,200
Wisconsin	$10,620 (7.08% effective)	$103,100	-$2,900
Iowa	$8,055 (5.37% effective)	$105,600	-$400

Observation: Illinois’ flat 4.95% becomes advantageous for high earners compared to progressive-tax Wisconsin, but Indiana’s lower flat rate still wins.

Illinois Cost of Living by Region

Converting hourly wages to annual salary in Illinois is straightforward thanks to the state’s constitutionally-mandated flat 4.95% income tax—one of the simplest tax systems in the United States.

Key Takeaways for Illinois Workers

Flat Tax Simplicity: Illinois’ 4.95% flat tax means everyone pays the same state rate (after $2,925 personal exemption) regardless of income. This makes Illinois calculations easier than progressive-tax states but means lower earners don’t get graduated tax relief. The flat tax is constitutionally protected and cannot be changed without voter approval of a constitutional amendment.

No Local Income Taxes: Unlike Ohio, Pennsylvania, or Indiana (which allows local taxes), Illinois has zero city or county income taxes anywhere in the state. However, this is offset by the second-highest property taxes in the nation and high sales taxes, especially in Chicago (10.25%).

Minimum Wage Progress: Illinois reached its $15.00 statewide minimum wage goal in 2025 after a six-year phase-in schedule. Chicago has its own higher minimum ($16.60 as of July 2025) with annual CPI increases capped at 2.5%. No further state increases are scheduled without new legislation.

Chicago vs. Rest of State: Chicago’s higher minimum wage ($16.60 vs. $15.00), higher sales tax (10.25% vs. 6.5-9%), and significantly higher cost of living create a distinct economic environment from the rest of Illinois. A $50,000 salary goes much further in Springfield or Rockford than in Chicago proper.

Standard Overtime Only: Illinois follows federal FLSA overtime (after 40 hours/week, time-and-a-half) with no daily overtime, double-time, or enhanced provisions like some other states. The federal salary threshold ($684/week) applies for overtime exemptions, with no higher Illinois-specific threshold.

Midwest Tax Competition: Illinois’ 4.95% flat tax is higher than Indiana (3.15%), similar to Wisconsin for middle incomes (4.41-6.27% progressive), but lower than Wisconsin for high earners. Many Illinois residents work across state lines in Indiana or Wisconsin, creating tax arbitrage opportunities.

Take-Home Reality: Illinois workers keep 71-82% of gross pay depending on income level. State tax takes 4.5-4.95%, federal progressive tax takes 6-20%, and FICA takes 7.65%. The flat state tax means Illinois burden is predictable and consistent across income levels.

High Property Tax Context: While Illinois income tax is moderate, property taxes averaging 2.16% of home value (vs. 0.99% nationally) significantly impact total tax burden, especially for homeowners in Cook County and Chicago suburbs. These taxes fund local services and schools but make Illinois one of the highest overall tax states despite the simple flat income tax.

Use this calculator for comparing Illinois job offers across regions, understanding true take-home pay in Chicago vs. downstate, negotiating salaries with Illinois cost-of-living and tax context, planning budgets based on flat 4.95% state tax plus federal taxes, and evaluating Illinois opportunities versus neighboring states like Indiana (lower taxes) or Wisconsin (progressive system).

Whether you’re earning Illinois’ $15.00 minimum wage, Chicago’s $16.60 minimum, or a six-figure salary in the Chicago suburbs, the flat 4.95% tax provides predictability and simplicity in calculating your take-home pay across Illinois’ economically diverse landscape from the high-cost Chicagoland area to affordable Central and Southern Illinois communities.
