illinoispaycheck.com is a free tool that helps people working in Illinois estimate their take-home pay — what actually lands in your bank account after federal taxes, state taxes, Social Security, and Medicare are withheld.
You enter your gross salary or hourly wage and a few basic details, and our calculator estimates your net pay for the 2026 tax year. The goal is simple: give you a fast, clear answer to the question "how much do I actually keep?"
Our estimates are based on published 2026 federal tax brackets, Illinois state tax rules, and current Social Security and Medicare rates. We update our figures when official tax rules change.
This calculator provides estimates for general informational purposes only. Your actual paycheck depends on factors specific to your situation — pre-tax deductions, benefits, additional withholding, and local taxes. We are not tax advisors. For decisions that matter, please consult a qualified tax professional.
