Frequently Asked Questions

What is the long-term capital gains tax rate?

Long-term rates (assets held 1+ year) are 0% for lower incomes, 15% for most taxpayers, and 20% for high earners. These are lower than ordinary income tax rates to encourage long-term investing.

How can I minimize capital gains tax?

Hold assets for at least a year for lower rates, use tax-loss harvesting, maximize tax-advantaged accounts, consider Qualified Opportunity Zones, and time sales strategically across tax years.

What is the capital gains tax rate?

Long-term capital gains (assets held over 1 year) are taxed at 0%, 15%, or 20% based on income. Short-term gains are taxed as ordinary income (10-37%). Most taxpayers pay 15% on long-term gains. High earners may also owe the 3.8% NIIT.

What is cost basis and why does it matter?

Cost basis is your original investment cost plus any improvements or reinvested dividends. It determines your capital gain: Sale Price - Cost Basis = Capital Gain. Accurate cost basis tracking can significantly reduce your tax bill.
