Tax Computation Summary
How to Use This Wisconsin Tax Calculator
Enter your annual gross income and select your filing status. Wisconsin's standard deduction phases out at higher incomes — the calculator handles this automatically. If you itemize, switch to "Itemized Deductions" and enter your total itemized deductions; Wisconsin provides a 5% credit (not a deduction) for itemizers.
The Formula
WI Taxable = Gross Income − WI Standard Deduction
Tax: 3.50% ($0–$14,320) + 4.40% ($14,320–$28,640) + 5.30% ($28,640–$315,310) + 7.65% (above)
Itemized Credit = Itemized Deductions × 5% (subtracted from tax, not income)
Example
WI std deduction: $12,760 − ($85,000 − $36,294) / 4 = $12,760 − $12,177 = $583
WI taxable income: $85,000 − $583 = $84,417
Tax: $14,320×3.5% + $14,320×4.4% + ($84,417−$28,640)×5.3%
= $501 + $630 + $2,956 = $4,087 | Effective rate: 4.81%
Wisconsin's Phasing Standard Deduction
Wisconsin's standard deduction is unique: it starts at $12,760 for single filers but reduces by $1 for every $4 of income above $36,294. At around $87,000 of income, a single filer has no standard deduction left, effectively paying tax on the full income minus any other Wisconsin adjustments. This phase-out makes Wisconsin's effective rate increase more steeply than the bracket rates suggest.
