Important: This is an educational estimate of federal tax on a typical capital gain. It does not include state or local taxes, the Net Investment Income Tax, special rates for collectibles or real estate depreciation, qualified small business stock exclusions, wash-sale adjustments, or all capital-loss carryover rules. The calculation assumes the other taxable income you enter is already calculated correctly and that the gain qualifies for the selected holding-period treatment. Actual liability can differ. See the IRS capital gains guidance.
