Example. A, a calendar-year taxpayer, purchases a house in 1985 that she occupies as her principal residence. In February 2004, A ceases to occupy the house and converts it to residential rental property. At the time of the conversion to residential rental property, the house's fair market value (excluding land) is $130,000 and adjusted depreciable basis attributable to the house (excluding land) is $150,000. Pursuant to this paragraph (b), A is considered to have placed in service residential rental property in February 2004 with a depreciable basis of $130,000. A depreciates the residential rental property under the general depreciation system by using the straight-line method, a 27.5-year recovery period, and the mid-month convention. Pursuant to §§ 1.168(k)-1T(f)(6)(iii)(B) or 1.1400L(b)-1T(f)(6) , this property is not eligible for the additional first year depreciation deduction provided by section 168(k) or section 1400L(b). Thus, the depreciation allowance for the house for 2004 is $4,137, after taking into account the mid-month convention (($130,000 adjusted depreciable basis multiplied by the applicable depreciation rate of 3.636% (1/27.5)) multiplied by the mid-month convention fraction of 10.5/12). The amount of depreciation computed under section 168, however, may be limited under other provisions of the Internal Revenue Code, such as, section 280A.
