You are required to report a taxable gain from the sale of securities and shares in the book-entry system, or a loss from the same, in MyTax or on Form 9A. You must include any foreign-sourced Capital gains and capital losses from trading with securities, too.
If you have capital gains from the sale of real estate, apartments and other property, file Form 9, and if you have capital gains from the sale of foreign-located property (such as real estate), file Form 16B. You can also use MyTax to file the information and amounts relating to the above forms.
