Frequently Asked Questions
Capital gains tax is a tax on the profit you make when you sell an investment for more than you paid. It applies to stocks, bonds, real estate, and other assets. The rate depends on your country, income level, and how long you held the asset.
In the US, short-term capital gains (assets held less than 1 year) are taxed at your ordinary income tax rate, which can be as high as 37%. Long-term gains (held over 1 year) get preferential rates of 0%, 15%, or 20% depending on your income. Many other countries have similar distinctions.
Yes. Tax-loss harvesting allows you to offset capital gains with capital losses from other investments. In the US, if your losses exceed your gains, you can deduct up to $3,000 per year against ordinary income and carry forward remaining losses to future years.
It depends on the type of dividend. Qualified dividends (from most US companies held for 60+ days) are taxed at long-term capital gains rates. Non-qualified or ordinary dividends are taxed at your regular income tax rate.
Common strategies include: holding investments for over one year to qualify for lower long-term rates, using tax-advantaged accounts (IRA, 401k, ISA), harvesting losses to offset gains, gifting appreciated assets, and timing your sales to stay in lower tax brackets.
