If you sold stock, bonds or other securities through a broker or had a barter exchange transaction (exchanged property or services rather than paying cash), you will likely receive a Form 1099-B. Regardless of whether you had a gain, loss, or broke even, you must report these transactions on your tax return.
Although you must report the full amount of the proceeds, you will also be asked for your basis (what you paid for the stock and any expenses such as brokerage fees). The total gain or loss will be entered on your tax return.
If you receive a Form 1099-B and do not report the transaction on your tax return, the IRS will likely send you a CP2000, Underreported Income notice. This IRS notice will propose additional tax, penalties and interest on this transaction and any other unreported income. Learn how to handle an underreporter inquiry (CP2000).
