The rule in Wisconsin
Wisconsin taxes only 70% of a long-term capital gain, as ordinary income — an effective 3.71% on the example below. Short-term gain is taxed in full.
- Wisconsin subtracts 30% of capital gain on assets held more than one year, and on any asset acquired from a decedent.
- Farm assets get 60% rather than 30% (§ 71.05(6)(b)9m), which this does not model.
Tax year 2026, from Wisconsin Statutes § 71.05(6)(b)9.
Work out the tax on your own gain
Prefilled for Wisconsin. Change what you paid, what you sold for and your other income — the federal band a gain lands in depends on everything underneath it, which is why the income field matters.
More than one year is long-term and gets the lower rates. Exactly one year is short-term — the clock starts the day after you bought.
Wages, self-employment, interest — everything but this gain. It decides which capital gains bracket the gain lands in.
Adds that state's own treatment of the gain, which is not always its income tax rate.

Assumptions
- One sale of a straightforward capital asset — shares, funds, crypto or investment property — by an individual US resident.
- The gain is stacked on your other taxable income, which is what decides the federal band.
- No main-home exclusion, depreciation recapture, collectibles rate, qualified small business stock, opportunity zone or 1031 exchange.
- State tax uses that state's rule for a gain allocated to it; a gain sourced to another state, or a part-year move, is not modelled.
- No local income tax: county in Maryland and Indiana, municipal in Ohio and Pennsylvania, city in New York.

|---|---|---|
| Sold within a year — short-term | $28,864 | $71,136 |

You have held this more than a year, so the long-term rates apply. The other row is what the same sale would have cost inside a year.

Frequently asked questions
Does Wisconsin tax capital gains?
Wisconsin taxes only 70% of a long-term capital gain, as ordinary income — an effective 3.71% on the example below. Short-term gain is taxed in full.
How much is capital gains tax in Wisconsin?
On a $100,000 long-term gain for someone earning $100,000, Wisconsin takes $3,710 — an effective 3.71%. Federal tax adds $15,000, for $18,710 in all.
Is short-term capital gain taxed differently in Wisconsin?
Yes. Wisconsin's relief applies to long-term gain only; a short-term gain is taxed in full as ordinary income.
How long do I have to hold something for the lower rate?
More than one year, federally. The holding period starts the day after you acquire the asset, so something bought on 10 March is long-term only if sold on 11 March the following year or later. Inside a year the gain is ordinary income at your income tax bracket, which for most people is 22% or 24% rather than 15%.
Do I pay Wisconsin tax on a gain if I moved away before selling?
Generally you are taxed by the state you were resident in when the gain was realised, and some states also tax gains sourced to property inside them however long you have been gone. A part-year move usually means allocating the gain between the two states. This page assumes a full-year Wisconsin resident.
