Flat 4.95% for 2026, unchanged. The exemption allowance rises from $2,850 (2025) to $2,925 per exemption for tax year 2026 (Bulletin FY 2026-15: "The personal exemption amount for tax year 2026 will increase to $2,925").

How this is worked out

5 steps
  1. Illinois (tax year 2026): Illinois starts from federal AGI with Illinois additions and subtractions.
  2. Income 85000 less deduction 0 and exemptions 2925 = taxable income 82075
  3. Exemptions: 2925 for the taxpayer(s)
  4. 4.95% on 82075 (0 to and above) = 4062.71
  5. Total state and local tax = 4062.71
