Introduction

The Modified Accelerated Cost Recovery System (MACRS) is used to recover the basis of most business and investment property placed in service after 1986. MACRS consists of two depreciation systems, the General Depreciation System (GDS) and the Alternative Depreciation System (ADS). Generally, these systems provide different methods and recovery periods to use in figuring depreciation deductions.

To be sure you can use MACRS to figure depreciation for your property, see Can You Use MACRS To Depreciate Your Property? in chapter 1.

This chapter explains how to determine which MACRS depreciation system applies to your property. It also discusses other information you need to know before you can figure depreciation under MACRS. This information includes the property's recovery class, placed-in-service date, and basis, as well as the applicable recovery period, convention, and depreciation method. It explains how to use this information to figure your depreciation deduction and how to use a general asset account to depreciate a group of properties. Finally, it explains when and how to recapture MACRS depreciation.
