How To Depreciate Property
This publication explains how you can recover the cost of business or income-producing property through deductions for depreciation (for example, the special depreciation allowance and deductions under the Modified Accelerated Cost Recovery System (MACRS)). It also explains how you can elect to take a section 179 deduction, instead of depreciation deductions, for certain property and the additional rules for listed property.
The depreciation methods discussed in this publication generally do not apply to property placed in service before 1987. If you want information about depreciating such property, see Publication 534.
