There are two types of capital gain: 1) capital gain on capital assets and 2) capital gain on securities. Capital assets include shares, membership cards, partnership shares, and other property connected to business. Securities include shares of public companies, vouchers, certificates, and derivatives. Capital gain is the increase in value when capital assets or securities are disposed of through sale. Gain is taxed differently based on whether the assets were held for less than one year or more than one year.
