Regardless of the type of bonds that are sold, any debt issue that is traded in the secondary market will post either a capital gain or loss, depending on the price at which the bonds were bought and sold. This includes government and municipal issues as well as corporate debt. Gains and losses on bond transactions are reported the same as with any other type of security, such as stocks or mutual funds, for the purposes of capital gains.
A capital gains tax (CGT) is a tax on capital gains, the profit realized on the sale of a non-inventory asset that was purchased at a cost amount that was lower than the amount realized on the sale. The most common capital gains are realized from the sale of stocks, bonds, precious metals and property.
