Paycheck examples

Four salaries, all computed by this site's own engine: single filer, paid every two weeks, no 401(k) deferral, no health premiums and no local tax. “Take-home” is what lands in the account each payday after every withholding below.

Payroll taxes on a Wisconsin paycheck

A $75,000 salary paid every two weeks, single filer, no 401(k) deferral, no health premiums and no local tax. Each line below comes off the gross before the money lands; the last column is what that line costs out of every dollar earned.

Payroll taxes come in two halves. The table above is the employee half — what is withheld from you. The employer half is paid on top of your salary and never shows up on a pay stub: a matching share of Social Security and Medicare, federal unemployment insurance (FUTA) and Wisconsin's own unemployment insurance. It changes what you cost to employ, not what you take home, and this calculator does not model it. Working for yourself means carrying both halves — the 1099 calculator prices that in.

Withholding forms and payroll rules in Wisconsin

What decides each line above: the certificate you file, the deductions it produces, and any local tax stacked on top.

• Every newly hired employee must give the employer a Form WT-4, because the federal W-4 cannot be used for Wisconsin withholding purposes, and the WT-4 doubles as new hire reporting.
• Employees claiming complete exemption must file a fresh WT-4 with their employer each year by April 30 or else they are treated as claiming zero withholding exemptions.
• Wisconsin has reciprocity agreements with Illinois, Indiana, Kentucky, and Michigan, and nonresident employees stop Wisconsin withholding only by handing their employer Form W-220 reciprocity declaration.
• A special arrangement with Minnesota lets Wisconsin residents' wages escape Wisconsin withholding only when those wages are already subject to Minnesota withholding, even though the two states have no formal reciprocity agreement.

Hourly pay in Wisconsin

Hourly wages are annualised the way the hourly-to-salary converter does it: 40 hours a week for 52 weeks, or 2,080 hours a year. The take-home column runs through the same engine as every other table on this page.

An extra dollar an hour is worth $2,080 of gross pay a year. At $35 an hour the total effective tax rate is 20.9%, which leaves $27.68 of every hour worked in the account.

Take-home by pay frequency

The same $100,000 salary, paid the four ways the calculator supports, under the assumptions above. Moving the payday changes the size of each deposit, never the yearly totals.

More scenarios at $100,000

Two setups readers ask about most, beside the single-filer baseline above: filing jointly, and deferring 6% of pay into a 401(k). Both stay biweekly, with no premiums and no local tax.

A 401(k) lowers the wages federal and Wisconsin income tax are figured on, but Social Security and Medicare stay charged on the full salary — and the deferral itself still leaves every paycheck, so take-home drops by the deferral minus the tax it saved.

Brackets and deductions

Wisconsin applies these rates to state-taxable income for single filers. Married couples filing jointly use the same rates against the joint thresholds in the source tables. The Wisconsin standard deduction of $14,660 (single) or $27,240 (married) comes off first.

What we do not model

The figures above exclude local and municipal income taxes, tax credits, dependent exemptions and credits, itemized deductions, additions for age or blindness, income-specific exemptions such as tips and overtime, phase-outs, alternative minimum tax, state disability insurance, and the Form W-4 details that change real withholding. They are an estimate, not tax advice — see the full disclaimer for what the model does and does not cover. The method shows how each figure above is calculated.
