What are Wisconsin's 2024 income tax brackets?

Wisconsin has four brackets: 3.50%, 4.40%, 5.30%, and 7.65%. For single filers in 2024 the 3.50% rate applies up to about $14,320, 4.40% to $28,640, 5.30% to $315,310, and 7.65% above that. Married-jointly thresholds are roughly 33% wider.

What is Wisconsin's standard deduction?

Wisconsin uses a sliding standard deduction that phases out as income rises. For 2024 the single maximum is about $13,230 and the married-jointly maximum about $24,490, both shrinking to zero at higher incomes. This tool models the headline maxima.

How do Wisconsin exemptions work?

Wisconsin grants a $700 personal exemption per taxpayer and per dependent. Taxpayers 65 or older get an extra $250. These exemptions are subtracted along with the standard deduction before the brackets apply.

Does Wisconsin tax retirement income?

Wisconsin taxes most retirement income, including 401(k) and IRA withdrawals and pensions, though Social Security benefits are exempt and some military and federal pensions qualify for exclusions. This general calculator does not apply retirement-specific exclusions.

Is federal tax included here?

No. This tool computes only the Wisconsin state income tax. Federal income tax and FICA are separate. Use it to estimate the state-level line of your overall tax picture.

Wisconsin levies a graduated state income tax with four brackets topping out at 7.65 percent. This calculator applies the 2024 thresholds for your filing status, subtracts the standard deduction and exemptions, and shows the tax due along with your effective and marginal rates.

How it works

Taxable income is computed before the brackets are applied:

taxable = AGI − standard deduction − exemptions

The personal and dependent exemptions are 700 dollars each. Wisconsin’s standard deduction is a sliding amount that starts near 13,230 dollars (single) or 24,490 dollars (joint) and phases down as income rises. The remaining taxable income is taxed in slices:

3.50% on the first bracket
4.40% on the next slice
5.30% on the next slice
7.65% on income above the top threshold

For a single filer the 2024 thresholds are roughly 14,320 dollars, 28,640 dollars, and 315,310 dollars.

Example

A single filer with 60,000 dollars AGI and one personal exemption subtracts the 13,230 standard deduction and 700 exemption, leaving about 46,070 dollars taxable. The tax is 3.50% of 14,320 (501) + 4.40% of the next 14,320 (630) + 5.30% of the remaining 17,430 (924) = roughly 2,055 dollars, an effective rate near 3.4 percent of AGI.

Notes

Because Wisconsin’s standard deduction phases out, higher earners lose the deduction and face the full 7.65 percent top rate. This simplified tool models the headline standard-deduction maxima and does not apply retirement-income exclusions, the married-couple credit, or the school-property-tax credit.
