Wisconsin Tax Tables
Wisconsin Tax Tables provide a complete reference of how state income tax is calculated for each supported year. These tables summarise the official rules issued by the Wisconsin Department of Revenue and present them in a clear structure that matches the calculations used in our Wisconsin Tax Calculator. They are useful for checking withholdings, estimating liability, reviewing historical tax years and understanding how state policy shapes taxable income.
Quick Access Tools
Tax Years
Select a tax year to view the official Wisconsin tax rates and rules used in our calculators. Each page shows the brackets or flat tax rate, deduction amounts, credit structures, withholding guidance and any year-specific updates published by the Wisconsin Department of Revenue. You can also access the matching Wisconsin Tax Calculator for precise calculations for that year.
How Wisconsin Calculates Income Tax
Wisconsin uses a progressive tax system where income is divided into brackets and each portion is taxed at its marginal rate. These rules determine how wages and other taxable income are assessed for Wisconsin returns, with updated tables released each year to reflect legislation and inflation changes. For a broader explanation of how tax tables work, see our Tax Tables guide.
Wisconsin supports resident, nonresident and part-year filing rules. The tax tables help clarify which thresholds apply when income is earned both inside and outside the state.
What Is Contained in the Wisconsin Tax Tables?
Each tax-year page provides a structured summary of the components Wisconsin uses to calculate individual income tax. While details vary by year, the state tax tables generally include the following elements:
- State tax brackets and marginal rates for each filing status.
- Standard deduction amounts for each filing status.
- Itemized deductions where permitted under Wisconsin law.
- Dependent and family-related credits including any child-based or filer-based reductions.
- State Earned Income Credit (EIC), including percentage match and income limits.
- Retirement income rules including partial or full exemptions for pensions or Social Security.
- State withholding tables used by employers for payroll calculations.
Together, these elements provide a transparent breakdown of how Wisconsin calculates tax for each year. This structure helps taxpayers review year-to-year changes, employers validate payroll withholding and financial planners analyse how Wisconsin’s rules differ from federal requirements. All values shown in our Wisconsin Tax Tables match the official figures published by the state.
Frequently Asked Questions
Planning note: Mid-year raise or new job in 2026
Update the WI calculator with your new annualized pay and adjust pre-tax contributions to stay on target. Consider a one-time extra WI withholding if you were under-withheld earlier in the year.
Should I choose Roth or Traditional contributions this year?
Traditional boosts take-home now; Roth keeps take-home lower now but withdrawals can be tax-free. Compare in our Roth vs Traditional tool.

Run interest/dividends via Schedule B and gains via Schedule D. Those feed federal AGI and can influence WI taxable income. Pre-tax contributions and certain adjustments can offset income to slightly lower your overall effective rate.
Adding an HSA mid-year—will WI reflect it?
