How do I convert hourly pay to an annual salary?

Multiply your hourly wage by the hours you work per week, then by the weeks you work per year. For a full-time job that is wage × 40 × 52, which equals 2,080 hours of pay per year before taxes.

What is the Illinois state income tax rate on wages?

Illinois uses a flat individual income tax rate of 4.95% on taxable income. There are no state tax brackets, so every dollar of Illinois taxable wage income is taxed at the same 4.95% rate.

What payroll taxes come out of an Illinois paycheck?

FICA taxes apply: 6.2% for Social Security up to the annual wage base and 1.45% for Medicare on all wages. These are federal payroll taxes withheld in addition to federal and Illinois income tax.

Is the federal tax figure here exact?

No, it is an estimate. It applies the standard deduction and 2024-style federal brackets for a single filer to approximate withholding. Your actual federal tax depends on filing status, dependents, and deductions.

Does Illinois tax overtime or bonuses differently?

Illinois applies the same flat 4.95% rate to all wage income, including overtime and bonuses. Bonuses may have different federal withholding at payroll, but the underlying Illinois rate does not change.

Comparing a job offer in dollars-per-hour to a salaried role is hard until you annualize the wage and see what actually lands in your bank account. This calculator turns any hourly rate into a gross annual salary and then estimates your Illinois take-home pay after payroll, state, and federal taxes.

How it works

The gross salary is a straight multiplication, and net pay subtracts the major tax layers:

gross salary = hourly wage × hours/week × weeks/year
FICA         = 6.2% Social Security (to wage base) + 1.45% Medicare
Illinois tax = 4.95% × (gross − standard deduction estimate)
federal tax  = bracket estimate on (gross − federal standard deduction)
net pay      = gross − FICA − Illinois tax − federal tax

Illinois uses a single flat 4.95% rate, which keeps the state portion simple. The federal piece is an estimate for a single filer using the standard deduction and ordinary brackets; your real federal tax depends on your full situation.

Example

At $30/hour, 40 hours a week, 52 weeks a year, the gross salary is $62,400. After FICA, Illinois’s 4.95% flat tax, and an estimated federal bill, take-home pay lands in the mid-$48,000s, or roughly $1,870 every two weeks.

Notes

Treat the federal number as a planning estimate, not exact withholding. It does not model dependents, 401(k) contributions, health premiums, or local taxes. The Illinois 4.95% and FICA figures are precise; the federal layer is approximate.
