Frequently Asked Questions

What are long-term vs short-term capital gains tax rates?

Long-term gains (held > 1 year) are taxed at 0%, 15%, or 20% depending on your income. Short-term gains (held ≤ 1 year) are taxed as ordinary income at your marginal rate, which can be up to 37%. Holding investments for over a year can save significant taxes.

How can I reduce my capital gains tax?

Strategies include holding for over one year, tax-loss harvesting, investing in tax-advantaged accounts (IRA, 401k), using the primary residence exclusion ($250k/$500k), and timing sales in low-income years. Charitable donations of appreciated assets avoid capital gains entirely.

How is ROI calculated?

ROI = (Final Value - Initial Investment) / Initial Investment x 100. For example, investing $10,000 and getting $15,000 back is a 50% ROI.

What is a good ROI?

A good ROI depends on the investment type. The S&P 500 averages about 10% annually. Real estate averages 8-12%. Anything above the risk-free rate (Treasury bonds) can be considered good.
