Capital gains tax is levied on profits from the sale of capital assets. There must be a capital asset that is transferred, resulting in a gain. Assets are classified as short-term (held 36 months or less) or long-term. Gains from long-term assets face lower tax rates (20%) than short-term (15%). Some capital gains are exempt, such as from the primary residence if another home is purchased, agricultural land replaced, or compulsory land acquisitions for industry.
