Capital Gains Tax in the United States

The United States taxes capital gains at different rates depending on the holding period. Short-term gains are taxed at ordinary income rates (0-37%), while long-term gains benefit from reduced rates of 0%, 15%, or 20%. A 3.8% Net Investment Income Tax (NIIT) may also apply.

Short-Term Capital Gains

Assets held for one year or less are considered short-term. Short-term capital gains are taxed at the taxpayer's ordinary income tax rates (0-37% depending on filing status and income level). These gains are added to the taxpayer's other income and taxed at the marginal rate.

Long-Term Capital Gains

Assets held for more than one year qualify for preferential long-term capital gains rates. The applicable rate depends on taxable income:

Net Investment Income Tax (NIIT)

An additional 3.8% tax applies to the lesser of net investment income or modified adjusted gross income exceeding $200,000 for single filers and $250,000 for married couples filing jointly. This tax applies to capital gains, dividends, interest, rental income, and other passive income.

Reporting and Filing

Capital gains and losses are reported on Schedule D (Form 1040). Brokers provide Form 1099-B with cost basis information. Capital losses can offset capital gains plus up to $3,000 of ordinary income per year ($1,500 if married filing separately). Unused losses carry forward indefinitely.
