|Generally, interest income is taxed as ordinary income in the year received and qualified dividends are taxed at a top rate of 20%. (Note that an additional 3.8% tax on investment income also may apply to both interest income and qualified (or nonqualified) dividends.) A capital gain (or loss) -- the difference between the cost basis of a security and its current price -- is not taxed until the gain or loss is realized. For individual stocks and bonds, you realize the gain or loss when the security is sold. However, with mutual funds you may have received taxable capital gains distributions on shares you own. Investments you (or the fund manager) have held 12 months or less are considered short term, and those capital gains are taxed at the same rates as ordinary income. For investments held more than 12 months (considered long term), those capital gains are taxed at no more than 20%, although an additional 3.8% tax on investment income may apply. The actual rate will depend on your tax bracket and how long you have owned the investment.
