Illinois Financial Snapshot (2026) — Tax Bracket Calculator
Bracket stack and standard deduction are the primary inputs for the tax bracket calculator in Illinois. Every row cites a primary public dataset. Numbers reflect the most recent vintage available; refresh cadence is documented in the methodology.
How the Tax Bracket Calculator Math Works Under Illinois Law
Your Illinois tax bracket calculator stacks federal and state income tax onto FICA (Social Security 6.2% + Medicare 1.45%). Illinois's 2026 structure is flat, with a top marginal rate of 4.95%[1]. Standard deduction for single filers: $0. Married filing jointly: $0.
| Taxable income (single) | Marginal rate |
|---|---|
| $0+ | 4.95% |
Calc-specific note: Marginal rate applies to each additional dollar above the bracket floor; effective rate = total tax ÷ taxable income and is always lower.
Worked example — Illinois
A Illinois single filer earning $100,000 in 2026 hits the federal 22% bracket above $48,475. Illinois's top marginal bracket is 4.95% — combined marginal ≈ 26.9%. Effective rate is always lower once deductions and lower-bracket income are included.

Sales tax surfaces in cost-of-living comparisons rather than in income calculators. Property tax shows up only on real-estate calculators. Each calculator on this page uses the Rockford, IL numbers above where the rule applies and federal-default values everywhere else.
