Wisconsin Paycheck Calculator

Wisconsin paychecks are affected by several layers of withholding. Federal income tax and FICA come out first, and Wisconsin also has its own state income tax. Unlike flat-tax states, Wisconsin uses a graduated income tax system, which means different portions of taxable income can be taxed at different rates.

• Federal income tax depends on gross pay, filing status, pay frequency, and federal withholding setup.
• Social Security and Medicare still apply to Wisconsin paychecks.
• Wisconsin state income tax is progressive, with current rates from 3.50% to 7.65%.
• Higher income can move part of your taxable pay into a higher Wisconsin bracket.
• Pre-tax deductions can lower the wages used for federal and Wisconsin income tax estimates.
• Your Wisconsin Form WT-4 helps your employer determine state withholding.

This calculator is a planning estimate. Actual employer withholding can vary with WT-4 setup, payroll software, deductions, bonuses, overtime, commissions, and irregular pay periods.

Wisconsin has a graduated individual income tax structure. For 2026, the bracket rates are 3.50%, 4.40%, 5.30%, and 7.65%, with different income thresholds for single, married filing jointly, and head of household estimates.

The calculator uses Wisconsin's progressive bracket structure for a practical state income tax estimate. Actual withholding can vary based on Wisconsin's standard deduction phaseout, credits, WT-4 adjustments, employer payroll withholding tables, and employer setup.

Form WT-4 is Wisconsin's employee withholding certificate. Employers use it to help determine how much Wisconsin income tax to withhold from each paycheck.

If your WT-4 information is outdated, missing, or does not match your current filing situation, your actual Wisconsin paycheck may be higher or lower than a calculator estimate.

Overtime, bonuses, and commissions can make a Wisconsin paycheck look lower than expected because a single pay period may look larger than usual to payroll software. That can increase withholding for that paycheck even if your annual tax result ends up different.

Use the overtime calculator for a quick overtime scenario, and the pay raise calculator when you are comparing a new salary or hourly wage.

Wisconsin state income tax, federal withholding, Social Security, Medicare, health insurance, retirement contributions, HSA or FSA deductions, post-tax deductions, garnishments, and employer payroll settings can all reduce your take-home pay from your gross salary or hourly earnings.

Your WT-4 setup and employer payroll software can also make real paychecks differ from this estimate. Bonuses, overtime, commissions, and irregular schedules can make withholding feel higher than normal in a single pay period.

If you are converting between salary and hourly pay, the salary to hourly calculator can help check the gross-pay side before estimating deductions.
