(a) Section 168 determines the depreciation allowance for tangible property that is of a character subject to the allowance for depreciation provided in section 167(a) and that is placed in service after December 31, 1986 (or after July 31, 1986, if the taxpayer made an election under section 203(a)(1)(B) of the Tax Reform Act of 1986; 100 Stat. 2143). Except for property excluded from the application of section 168 as a result of section 168(f) or as a result of a transitional rule, the provisions of section 168 are mandatory for all eligible property. The allowance for depreciation under section 168 constitutes the amount of depreciation allowable under section 167(a). The determination of whether tangible property is property of a character subject to the allowance for depreciation is made under section 167 and the regulations under section 167.
(b) This section is applicable on and after February 27, 2004.
