How an hourly paycheck is built in Illinois
An hourly paycheck starts from something a salaried one does not have: a timesheet. Gross pay is the sum of every category of hour you worked, each at its own rate, before a single tax is applied.
| Category | Hours | Rate | Pay |
|---|---|---|---|
| Regular | 80 | $25.00 | $2,000.00 |
| Overtime (1.5×) | 6 | $37.50 | $225.00 |
| Double time (2×) | 4 | $50.00 | $200.00 |
| Gross pay | 90 | — | $2,425.00 |
Only once that total exists does withholding begin. The Illinois piece is the simplest part — 4.95% of the whole thing, less any allowances from Form IL-W-4 — while federal withholding depends on your Form W-4 and on annualizing the paycheck. Our guide to what comes out of an Illinois paycheck walks through each deduction in order.
Overtime rules that apply in Illinois
Illinois relies on the federal Fair Labor Standards Act for the core rule and adds a handful of state protections on top.
- Time and a half past 40 hours a week. The workweek is a fixed, recurring 168-hour period your employer designates; hours are not averaged across two weeks even on a bi-weekly pay cycle.
- No daily overtime. Unlike California, Illinois does not pay overtime for hours past eight in a day. Four ten-hour days is 40 straight-time hours.
- The regular rate is not always the base rate. Non-discretionary bonuses, shift differentials and commissions must be blended into the regular rate before the 1.5 multiplier applies.
- One Day Rest in Seven. Most employees are entitled to 24 consecutive hours of rest in every consecutive seven-day period, plus a 20-minute meal break for shifts of 7.5 hours or longer.
- Exempt employees do not get overtime — but the exemption depends on duties and salary level, not on being paid a salary alone.
A heavy overtime week produces a paycheck that looks over-taxed because payroll annualizes it. The extra withholding is reconciled when you file, and Illinois withholding is unaffected because the state rate is flat.
Illinois minimum wage in 2026
| Category | Rate | Notes |
|---|---|---|
| Illinois standard minimum wage | $15.00 | Statewide since January 1, 2025 |
| Tipped minimum wage | $9.00 | Tips must bring the total to $15.00 |
| Youth minimum (under 18) | $13.00 | Fewer than 650 hours in the calendar year |
| Chicago (4+ employees) | $17.05 | From July 1, 2026 |
| Chicago tipped | $12.96 | Tip credit held at 24% — the One Fair Wage phase-out is paused |
| Suburban Cook County | $15.40 | From July 1, 2026, in municipalities that have not opted out |
At the state minimum of $15.00 an hour, a full-time schedule of 40 hours a week is $31,200 a year gross. A single filer with no dependents takes home roughly $25,705 of that once federal withholding, the Illinois 4.95% and FICA come out — worth checking against the average salary in Illinois for context on where that sits.
Hourly to annual: the quick conversions
The shortcut most people use is to double the hourly rate and add three zeros — $25 an hour is roughly $50,000 a year — which works because 40 hours × 52 weeks is 2,080 hours. Here is the actual arithmetic at common rates, with estimated take-home for a single filer with no dependents.
| Hourly rate | Weekly gross | Annual gross | Est. annual take-home |
|---|---|---|---|
| $15.00 | $600 | $31,200 | $25,705 |
| $18.00 | $720 | $37,440 | $30,410 |
| $20.00 | $800 | $41,600 | $33,546 |
| $25.00 | $1,000 | $52,000 | $41,388 |
| $30.00 | $1,200 | $62,400 | $49,230 |
| $35.00 | $1,400 | $72,800 | $56,441 |
| $40.00 | $1,600 | $83,200 | $63,243 |
| $50.00 | $2,000 | $104,000 | $76,846 |
If you are on a salary rather than an hourly rate, the Illinois salary calculator handles the conversion in the other direction and shows net pay for every pay frequency at once.
Pay frequency and what Illinois law requires
The Illinois Wage Payment and Collection Act sets the floor. Most employees must be paid at least semi-monthly. Wages for a semi-monthly or bi-weekly period are due within 13 days of the period ending; weekly wages within seven days; daily wages within 24 hours. Executive, administrative and professional employees may be paid monthly, with wages due within 21 days.
| Frequency | Paychecks a year | Typical hours per paycheck |
|---|---|---|
| Weekly | 52 | 40 |
| Bi-weekly | 26 | 80 |
| Semi-monthly | 24 | 86.67 on average |
| Monthly | 12 | 173.33 on average |
Semi-monthly is the awkward one for hourly staff, because the pay period rarely aligns with the Sunday-to-Saturday workweek used for overtime. Employers handle this by calculating overtime on the workweek and paying it in whichever semi-monthly period the week ends.
Deductions your employer may legally take
Illinois is stricter than most states here. Section 9 of the Wage Payment and Collection Act allows a deduction from wages only when it is required by law, is for the employee's benefit, is expressly authorized in writing by the employee at the time the deduction is made, or is made under a valid court order such as a wage deduction order. An employer cannot unilaterally dock your pay for a cash-register shortage, a broken tool or a customer walkout without that written authorization.

Multiply your hourly rate by the hours you worked, add overtime at 1.5 times your regular rate for anything past 40 hours in a week, and that is gross pay. From there, subtract any pre-tax benefit deductions, then federal income tax withholding, Illinois income tax at 4.95%, Social Security at 6.2% and Medicare at 1.45%. The calculator above does all of it at once, including a second pay rate if you work two positions for the same employer.
The Illinois state minimum wage is $15.00 an hour in 2026, having reached that level on January 1, 2025 at the end of a six-year phase-in. Tipped employees may be paid $9.00 as long as tips bring them to at least $15.00. Workers under 18 who work fewer than 650 hours in a calendar year may be paid $13.00. Two local ordinances go higher: Chicago is $17.05 an hour from July 1, 2026 for employers with four or more employees, and suburban Cook County is $15.40.
Illinois follows the federal Fair Labor Standards Act: non-exempt employees earn 1.5 times their regular rate for every hour past 40 in a workweek. Illinois does not have a daily overtime rule, so a 12-hour shift does not trigger overtime on its own — only the weekly total matters. One state-specific addition is the One Day Rest in Seven Act, which entitles most employees to 24 consecutive hours off in every consecutive seven-day period. Non-discretionary bonuses and shift differentials have to be folded into the regular rate before the 1.5 multiplier is applied, which is why a bonus can quietly raise your overtime rate.
At $20 an hour and 40 hours a week, gross pay is $41,600 a year, or $1,600 per bi-weekly paycheck. A single filer with no dependents keeps roughly $33,546 a year — about $1,290 per bi-weekly paycheck — after $2,812 in federal withholding, $2,059 in Illinois tax and $3,182 in FICA. Add a health premium or a 401(k) contribution and the take-home figure moves accordingly; enter your own numbers above for an exact result.
Bi-weekly means every two weeks — 26 paychecks a year, always on the same weekday, with two months in the year containing three paydays. Semi-monthly means twice a month, usually the 15th and the last day — 24 paychecks a year, larger individually but landing on different weekdays. Your annual pay and annual tax are identical either way. What differs is the per-paycheck amount and, for hourly workers, how neatly the pay period lines up with the workweek used to calculate overtime.
Not at a higher rate, no — though the paycheck can make it look that way. Overtime is ordinary wages taxed exactly like regular hours. What happens is that payroll annualizes the bigger paycheck: a week with 15 hours of overtime is treated, for that one calculation, as though you earn that much every week, which pushes the withholding into a higher bracket for that paycheck. It evens out over the year and any excess comes back as a refund. Illinois withholding never changes at all, because 4.95% of a bigger number is still 4.95%.
Illinois has no statutory definition of full-time employment for general purposes — it is up to your employer. Two thresholds do matter in practice: 40 hours a week is the point at which federal overtime begins, and 30 hours a week is the Affordable Care Act definition an employer with 50 or more full-time equivalents uses to decide who must be offered health coverage.
Yes. Under the Paid Leave for All Workers Act, in force since January 2024, most Illinois employees accrue one hour of paid leave for every 40 hours worked, up to 40 hours per 12-month period, and may use it for any reason without having to explain why. Employers can front-load the 40 hours instead of accruing them. Chicago and Cook County employees are covered by their own, more generous local ordinances rather than the state Act.
