It's nice to own stocks, bonds, and other investments. Nice, that is, until it's time to fill out your federal income tax return. At that point, you may be left scratching your head. Just how do you report your investments and how are they taxed?

Is it ordinary income or a capital gain?

To determine how an investment vehicle is taxed in a given year, first ask yourself what went on with the investment that year. Did it generate interest income? If so, the income is probably considered ordinary. Did you sell the investment? If so, a capital gain or loss is probably involved. (Certain investments can generate both ordinary income and capital gain income, but we won't get into that here.)

If you receive dividend income, it may be taxed either at ordinary income tax rates or at the rates that apply to long-term capital gain income. Dividends paid to an individual shareholder from a domestic corporation or qualified foreign corporation are generally taxed at the same rates that apply to long-term capital gains. Long-term capital gains and qualified dividends are generally taxed at special capital gains tax rates of 0 percent, 15 percent, and 20 percent depending on your taxable income. (Some types of capital gains may be taxed as high as 25 percent or 28 percent.) The actual process of calculating tax on long-term capital gains and qualified dividends is extremely complicated and depends on the amount of your net capital gains and qualified dividends and your taxable income. But special rules and exclusions apply, and some dividends (such as those from money market mutual funds) continue to be treated as ordinary income.

The distinction between ordinary income and capital gain income is important because different tax rates may apply and different reporting procedures may be involved. Here are some of the things you need to know.
