Investments by themselves are not reported, but you must report any trading activity that results in a gain or a loss, as well as interest and dividend income. You should get a tax statement from each broker service. You may get a “combined tax statement“ or you may get a separate 1099-DIV, 1099-INT, and 1099-B, which report dividend income, interest income, and capital gains and losses. All these statements must be included on your tax return. In the unusual event that you have invested with a service that does not issue tax statements, you must still report interest, dividends, and capital gains on your tax return.
