Federal taxes and FICA

Your paycheck also pays federal income tax from the 2026 brackets, Social Security tax of 6.2% on wages up to $184,500, and Medicare tax of 1.45% on all wages, plus 0.9% on wages above $200,000 for single filers.

What this estimate leaves out

It uses 2026 federal rules and each state’s published rates, brackets and standard deductions. Head of household is treated like single for state tax. It does not include every state credit, deduction or phase-out, so your real withholding can differ. Local income taxes, such as city or county taxes, are included only if you enter a rate. Use your pay stub, your state revenue department, or a tax professional for exact figures.

Frequently asked questions

Why does my Illinois paycheck look different from this estimate?

Employers use withholding tables, and your W-4, health insurance premiums, local taxes and benefits all change the real number.

Is this the same as the general take-home pay calculator?

It uses the same federal calculation but applies Illinois’s actual state rules instead of a flat percentage you enter yourself.
