How the Wisconsin Standard Deduction Works
For 2025, the Wisconsin standard deduction is $12,760 for single filers and $23,620 for married filing jointly. That single-filer figure is well below the $15,000 federal standard deduction, which matters because the state and federal deductions are claimed separately: the federal deduction lowers your federal taxable income, while the Wisconsin deduction lowers the income that Wisconsin taxes at its own bracket rates. A larger state standard deduction shields more of each paycheck from state income tax before any bracket applies.
Wisconsin's standard deduction is $12,760 for single filers and $23,620 for married filing jointly. The deduction is subtracted from gross income before bracket rates are applied; itemized deductions can be used instead when they exceed the standard amount.
The standard deduction is the amount you can subtract from gross income without itemizing. In Wisconsin, it is claimed before Wisconsin's bracket rates apply, which is why a larger deduction directly lowers the income that gets taxed.

What This Page Cannot Tell You
The standard-deduction figures above describe the statutory state-level rules. Your actual state tax liability depends on credits (earned-income credit, child credit, dependent credit), itemized deductions, retirement-income exclusions, local-government taxes (city or county income tax in some states), and federal taxable-income conformity rules. None of those interactions are computed here.
