Wisconsin Paycheck Calculator
Work out Wisconsin take-home pay from gross, pay frequency, filing status and pre-tax deductions. Federal and FICA are estimated for you; enter the WI...
Estimate pay before Wisconsin state and local withholding, then enter the amount from current official state guidance.
Wisconsin state withholding is not calculated automatically. Enter the amount for this pay period from an official worksheet or genuine payroll record to include it; leave it blank to see pay before state withholding. You can enter a known local withholding amount separately. Nothing here reproduces Publication W-166, so the Wisconsin figure is included only when you copy it from payroll or an official worksheet, and a WT-4A agreement can make that figure specific to one person's year. This calculator is an estimate workspace, not a payroll filing service. Verify every assumption with current official instructions.
Wisconsin withholding is copied in, not computed
Wisconsin income tax is not calculated on this page. The Department of Revenue points employers to Publication W-166, its Withholding Tax Guide, for the methods they must use, and the certificate a worker files sets the exemptions those methods apply. Wisconsin also lets the amount be reset mid-year: Form WT-4A is a worksheet on which an employee estimates Wisconsin income, the standard deduction and exemptions, credits and tax already withheld, then agrees with the employer on what is withheld through the rest of the year. Two people on identical pay can end up with different Wisconsin amounts, and only their own records show which.
Getting the Wisconsin line into the estimate correctly
Enter the Wisconsin withholding shown for one pay period on a statement your employer actually issued, matched to the pay frequency selected here. A figure produced under a WT-4A agreement reflects a whole estimated year, so it cannot be rebuilt from one period of gross pay; copying it across is the only accurate route. If no statement is to hand, the Department of Revenue's guide for employers is the published method, and nothing on this page stands in for it. What comes back here is a federal estimate with your own Wisconsin figure subtracted afterwards, not a payroll calculation of your Wisconsin tax.
Frequently asked questions
Does this page calculate Wisconsin withholding?
No. Publication W-166, the Department of Revenue's Withholding Tax Guide, is the method employers work from, and this page implements none of it. The Wisconsin field is optional and starts blank; while it stays blank the summary presents a federal-and-FICA figure and says on its face that Wisconsin tax has not been taken off. Whatever you type is treated as your own number for this one pay period, never as something the page worked out.
Why is my Wisconsin withholding not a steady share of each check?
The exemptions on the worker's Wisconsin certificate change what the employer's method produces, and pre-tax items change the wages that method is applied to. A Form WT-4A agreement changes it further, because it sets an amount for the periods left in the year after counting tax already withheld. A single check is therefore not a fixed proportion of gross pay, which is why this page asks you to supply the figure.
