How Illinois taxes your paycheck
Illinois taxes wages at a flat 4.95% in 2026. The same rate applies to every taxable dollar, so a raise is taxed at the same rate as the rest of your pay.
Before the brackets apply, Illinois allows a personal exemption of $2,925 per filer.

Ways to raise your take-home pay in Illinois
- 01
Contribute pre-tax
Traditional 401(k) contributions (up to $24,500 in 2026) and HSA contributions through payroll lower federal taxable income, and in most cases Illinois taxable income too.
- 02
Update your W-4
If you got a large refund last year, too much is being withheld. A new W-4 puts that money in each paycheck instead.
- 03
Claim the 2026 federal deductions you qualify for
Qualified overtime premium (up to $12,500, or $25,000 joint) and tips (up to $25,000) can be deducted on your federal return for 2025 through 2028.
