Free USA Capital Gains Tax Calculator — 2026 IRS Rates

Capital gains tax in the United States is levied on profits from the sale of capital assets including stocks, bonds, mutual funds, ETFs, real estate, and cryptocurrency. The USA tax code distinguishes between short-term capital gains (assets held less than one year, taxed as ordinary income up to 37%) and long-term capital gains (assets held one year or more, taxed at preferential rates of 0%, 15%, or 20%). Additionally, high-income American investors may owe the 3.8% Net Investment Income Tax (NIIT) on capital gains. This free USA Capital Gains Tax Calculator helps American investors, day traders, real estate sellers, and crypto traders accurately estimate their federal capital gains tax liability using the latest 2026 IRS rates and brackets.

🇺🇸 How USA Capital Gains Tax Works

In the United States, capital gains are classified by holding period. Short-term gains (assets held < 12 months) are taxed at your ordinary income tax rate (10%-37%). Long-term gains (assets held ≥ 12 months) receive preferential rates: 0% for income up to ~$47,025 (single), 15% up to ~$518,900, and 20% above that threshold. The IRS requires taxpayers to report all capital gains on Schedule D. Crypto, NFTs, and other digital assets are treated as property by the IRS, meaning all USA cryptocurrency gains are taxable.

USA Capital Gains Tax Strategies

Hold investments for at least 12 months to qualify for the preferential USA long-term capital gains rates (0%/15%/20% vs up to 37%).
Use tax-loss harvesting — sell losing investments to offset gains. The IRS allows up to $3,000 in net capital losses to offset ordinary income annually.
Consider donating appreciated stocks to charity — you avoid capital gains tax entirely AND get a charitable deduction on your USA federal return.
Use tax-advantaged accounts (401k, IRA, HSA) where capital gains are either tax-deferred or tax-free in the United States.
Be aware of the IRS wash-sale rule — you cannot buy back a 'substantially identical' security within 30 days of selling it at a loss.

Is crypto taxable in the USA?
Yes. The IRS classifies cryptocurrency as property. Every sale, trade, or exchange of crypto in the United States is a taxable event. This includes trading Bitcoin for Ethereum, spending crypto on purchases, and receiving crypto as payment.
How is real estate capital gains taxed in the USA?
Profits from selling real estate in the United States are taxed as capital gains. However, the IRS provides a major exclusion: primary residence sellers can exclude up to $250,000 ($500,000 married) in gains if they lived in the home for 2 of the last 5 years (Section 121 exclusion).

The IRS wash-sale rule prevents American taxpayers from claiming a tax loss if they buy a 'substantially identical' security within 30 days before or after the sale. The disallowed loss is added to the cost basis of the new purchase.
