Tax-option corporations; depreciation.

For taxable years beginning before January 1, 2014, a tax-option corporation shall compute amortization and depreciation under the federal Internal Revenue Code as amended to December 31, 2000, except that property first placed in service by the taxpayer on or after January 1, 1983, but before January 1, 1987, that, under s. 71.04 (15) (b) and (br), 1985 stats., is required to be depreciated under the Internal Revenue Code as amended to December 31, 1980, and property first placed in service in taxable year 1981 or thereafter but before January 1, 1987, that, under s. 71.04 (15) (bm), 1985 stats., is required to be depreciated under the Internal Revenue Code as amended to December 31, 1980, shall continue to be depreciated under the Internal Revenue Code as amended to December 31, 1980. Any difference between the adjusted basis for federal income tax purposes and the adjusted basis under this chapter shall be taken into account in determining net income or loss in the year or years for which the gain or loss is reportable under this chapter. If that property was placed in service by the taxpayer during taxable year 1986 and thereafter but before the property is used in the production of income subject to taxation under this chapter, the property’s adjusted basis and the depreciation or other deduction schedule are not required to be changed from the amount allowable on the owner’s federal income tax returns for any year because the property is used in the production of income subject to taxation under this chapter. If that property was acquired in a transaction in taxable year 1986 or thereafter in which the adjusted basis of the property in the hands of the transferee is the same as the adjusted basis of the property in the hands of the transferor, the Wisconsin adjusted basis of that property on the date of transfer is the adjusted basis allowable under the Internal Revenue Code as defined for Wisconsin purposes for the property in the hands of the transferor.
