MACRS - Wikipedia, the free encyclopedia
There's a table in the link.Under MACRS a taxpayer must compute tax deductions for depreciation of [[tangible property] using specified lives and methods. Assets are divided into classes by type of asset or by business in which the asset is used. (See tables of classes below.) Where a general class based on the nature of the asset applies (00.xx classes below), that class takes precedence over the use class.
For each class, three lives are specified: one for regular depreciation (GDS in the tables below), one for the alternative depreciation system (ADS), and a class life. Taxpayers may be required to use ADS or otherwise may elect which of the three lives to use. Lives for personal property vary from 3 years to 20 years.
