Short-term vs long-term gains in Wisconsin

Sell within a year and the federal government taxes the gain as ordinary income. On a $50,000 gain with the same income, that means $14,889 of tax if you sell short-term against $10,178 if you hold past one year, a difference of $4,712. Wisconsin also treats the two differently: 7.6% on short-term gains and 5.4% on long-term gains.

How we estimate Wisconsin tax

Up to 7.65%; 30% of long-term gains excluded (≈5.36% effective). Where a state taxes gains as ordinary income on a sliding scale, the calculator applies the rate shown above to the whole gain, so for most people it is an upper estimate. Local and city income taxes are not included.
