For 2009, your residential rental property may qualify for a special 30% or 50% depreciation allowance. This allowance is figured before you figure your regular depreciation deduction.
Among other qualifications, this property must be located in the New York Liberty Zone, the Gulf Opportunity Zone, the Kansas disaster area, or other federally declared disaster areas. See Publication 946, chapter 3, for details. Also see the Instructions for Form 4562, Line 14.
If you qualify for, but choose not to take, a special depreciation allowance, you must attach a statement to your return. The details of this election are in Publication 946, chapter 3, and the Instructions for Form 4562, Line 14.
