Wisconsin Tax Calculator

The Wisconsin (WI) Tax Calculator is updated for the 2026/27 tax year and helps estimate your state income tax, federal tax, and FICA/Medicare obligations. Wisconsin uses a progressive income tax structure with four brackets and allows multiple credits, such as the Earned Income Credit and Homestead Credit. This calculator simplifies tax planning by integrating both state and federal calculations.

Filers can add dependents, adjust deductions, or include retirement contributions for a detailed overview of their tax liability and take-home pay. The calculator reflects current brackets and thresholds as published by the Wisconsin Department of Revenue.
