Wisconsin Capital Gains Tax Calculator
Wisconsin taxes capital gains as ordinary income at the state level, which means a gain on selling shares, property or other investments is added to your other income and taxed using the Wisconsin income tax brackets, with no separate preferential long-term rate like the federal system provides. This calculator estimates the Wisconsin state tax on a capital gain by stacking the gain on top of your other taxable income and applying the sourced Wisconsin Department of Revenue brackets for tax year 2024, then taking the difference. Enter your gain, your other annual taxable income and your filing status to see the state tax attributable to the gain and the effective rate on it. The result is the Wisconsin state portion only; federal capital gains tax, which has separate short-term and long-term rates set by the IRS, is calculated separately. Because the gain stacks on your other income, the same gain is taxed at a higher rate the more you already earn. Some states provide specific exclusions or preferential treatment for certain gains; this tool uses the standard ordinary-income method and links the Wisconsin Department of Revenue so you can confirm any special rule that applies to you.

Wisconsin's standard deduction is not a fixed amount for most filers. It phases out as income rises above relatively low thresholds.

For married filing jointly, the maximum $23,700 deduction phases out above approximately $22,010 and is fully eliminated above approximately $220,600. Filers above these upper thresholds receive no standard deduction. Wisconsin Statutes §71.05(22).
Is Wisconsin a high-tax state?
Wisconsin is generally considered a moderate-to-high-tax state. Its 7.65% top income tax rate is among the higher rates in the Midwest. Wisconsin also has a 5% state sales tax (municipalities can add more), and property taxes that are above the national average. However, Wisconsin's income tax brackets are fairly wide for the middle brackets, meaning the 5.3% rate applies across a broad range of middle-class incomes. The combination of income, property, and sales tax places Wisconsin's overall state and local tax burden above the national average.

The 7.65% top rate is one of the higher top rates among Midwestern states, though it is lower than states like California (13.3%) or New York. Wisconsin Statutes §71.06.
