Wisconsin taxes capital gains as ordinary income. Wisconsin has four graduated brackets from 3.5% to 7.65%. Most income falls in the 4.4% and 5.3% bands; the 7.65% top rate applies only above about $333,000 single. Social Security is exempt.
Note on 2026 figures: The 3.5%/4.4%/5.3%/7.65% rates are fixed for 2026, but the Department of Revenue had not yet posted its official 2026 bracket dollar amounts or standard deduction at build. Thresholds and the standard deduction shown are the 2026 inflation-indexed figures reported by the Tax Foundation, to be replaced when the DOR posts its 2026 tables.

How capital gains tax works in Wisconsin
Long-term gains (assets held more than a year) get the federal 0/15/20% rates — but the rate depends on where the gain lands once it is stacked on top of your other taxable income, so part of a gain can be taxed at 0% and the rest at 15%. Short-term gains are taxed as ordinary income. On top of that, the 3.8% Net Investment Income Tax applies once your income clears $200,000 (single) or $250,000 (married-jointly).
