Methodology & Source
Illinois state tax figures sourced from Illinois Department of Revenue (https://tax.illinois.gov/), citing 35 ILCS 5/201 — flat 4.95% rate (Illinois Constitution art. IX, § 3 prohibits graduated rates). Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). Illinois's married-filing-jointly and head-of-household figures have been independently verified against the source above.
This is an estimate based on standard single-filer federal, FICA, and IL state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions (401k, health insurance), and other factors.
