How This Calculator Works
Calculation methodology and assumptions
Compares your current ("Current State (Moving From)", defaulting to Illinois itself so results start at a neutral $0 until you pick your real origin state) state tax burden to Illinois's tax environment. Both sides are computed the same way, using each state's own real income tax brackets/flat rate (not a generic guess or a flattened top-rate shortcut): Illinois has a 4.95% flat tax, 1.88% property tax, and 6.25% sales tax. The Current State Tax Rate / Property Tax Rate / Sales Tax Rate fields are editable, honestly-labeled prefills derived from whichever state you select above -- change the selector and they update to match; type a different number directly to manually override any one of them. Estimates are simplified — actual savings depend on deductions, local taxes, and exemptions.
Example Calculation
How does Illinois's tax burden compare for a typical household?
Consider a household earning $85,000/year that owns a $299,000 home (Illinois's median) and spends about $30,000/year on taxable purchases. Federal income tax (2026 brackets) plus FICA comes to roughly $16,373. Illinois's flat 4.95% income tax adds about $4,208. Property tax at 1.88% adds $5,621/year, and sales tax at 6.25% on taxable spending adds roughly $1,875/year.
Result: Total estimated tax burden: approximately $28,076/year, or about 33.0% of gross income (24.2% from income taxes and FICA alone). The total effective tax rate varies dramatically by state — no-income-tax states can run 10+ percentage points lower than high-tax states at the same income, a difference worth thousands of dollars a year.

Our editorial standardsFrequently Asked Questions
Will I save on taxes by moving to Illinois?
It depends entirely on which state you're moving FROM -- select it above (it defaults to Illinois itself, which always shows $0 savings, since that's not a real relocation). Illinois's income tax is a flat 4.95%, with property tax at 1.88% and sales tax at 6.25%.
Why does this calculator show $0 savings by default?
The "Current State (Moving From)" selector defaults to Illinois itself so the page never fabricates a savings number for an arbitrary, unselected origin state. Choose your actual current state from the dropdown to see a real, apples-to-apples comparison using both states' own tax brackets.
