About this tool

Enter your taxable income, the gain, whether you held the asset more than a year and your filing status. Long-term gains are taxed at 0, 15 or 20 percent and short-term gains at ordinary rates, stacked on top of your income. Figures are for the 2026 tax year and can change. A guide only, check irs.gov or a tax professional.

Short and long term

Assets held for a year or less produce short-term gains that are taxed like ordinary income. Assets held longer than a year get the lower long-term rates of 0, 15 and 20 percent, based on your taxable income.

Example

A single filer with $80,000 taxable income and a $25,000 long-term gain pays 15 percent on the whole gain, about $3,750.

Not included

The 3.8 percent net investment income tax for high earners, state tax, collectibles at 28 percent and the home sale exclusion are not modelled.

計算示例

With the boxes at their starting values (Taxable income excluding the gain ($): 80000; Capital gain ($): 25000; Held for: More than a year; Filing status: Single), the tool shows: Average rate on the gain: 15.0%; Gain after federal tax ($): 21,250; Federal capital gains tax ($): 3,750. Change any box to see your own numbers. The result updates as you type, and nothing leaves your browser.
