{{Main|Capital gains tax}}
Most jurisdictions imposing an income tax treat [[capital gain]]s as part of income subject to tax. Capital gain is generally a gain on sale of capital assets—that is, those assets not held for sale in the ordinary course of business. Capital assets include personal assets in many jurisdictions. Some jurisdictions provide preferential rates of tax or only partial taxation for capital gains. Some jurisdictions impose different rates or levels of capital-gains taxation based on the length of time the asset was held. Because tax rates are often much lower for capital gains than for ordinary income, there is widespread controversy and dispute about the proper definition of capital.
