HOW THE ILLINOIS ESTIMATE WORKS

What the 2026 calculation includes.

Illinois publishes a 4.95% withholding rate for 2026 and a $2,925 regular exemption allowance. TakeHomeMeter models one exemption for Single/Head of Household and two for Married Filing Jointly.

What can make your actual paycheck different?

Actual IL-W-4 allowances can differ, particularly for dependents and additional allowances.

Important assumptions

  • Standard deduction rather than itemized deductions.
  • No dependents, tax credits, bonuses or stock compensation.
