Property Depreciation Methods: MACRS
Last Updated August 23, 2022
Depreciation represents the decline in the value of property, and erosion of investment in that property, that occurs over time. Since the erosion of investment continues until the property can no longer be used, the tax code grants taxpayers depreciation allowances as a mechanism for recovering the capital invested in an asset.
The modified accelerated cost recovery system (MACRS) is used to depreciate all tangible property placed in service after Dec. 31, 1986 (except certain tangible property). MACRS (and its predecessor, ACRS) was intended to alleviate several income tax problems, such as complex computations, salvage value estimates, useful life litigation, and other similar issues. ACRS remains in effect for property placed in service during 1981 through 1986.
What information is needed to determine an asset’s MACRS deduction?
To calculate MACRS depreciation expense, at a minimum, a taxpayer must:
- Identify the item of depreciable property (often referred to as the “asset”)
- Determine whether the property is depreciable
- Determine who may take depreciation
- Determine the depreciable basis
- Determine when the property is considered to be placed in service
- Determine whether the property is eligible for bonus depreciation
- Determine the applicable recovery period
- Determine the applicable depreciation method (e.g., 200% declining balance, 150% declining balance, or straight-line method)
- Determine the applicable placed-in-service convention (e.g., midmonth, half-year, or midquarter)
- Determine whether to make any available depreciation elections

What requirements must be met for property to be depreciable under §168?
To be depreciable under MACRS, property must be tangible and of a character subject to the allowance for depreciation (often referred to as a “wasting asset”). The property must also be used in a trade or business or held for the production of income. Though there are exceptions, most tangible property of this type is subject to wear and tear and is therefore a wasting asset.
What are the MACRS recovery classes?
MACRS provides eight categories of property with a recovery period assigned to each category. In addition, MACRS provides three categories that cover most real estate: residential rental property with a 27.5-year recovery period, nonresidential real property with a 31.5-year recovery period, and nonresidential real property with a 39-year recovery period. The categories include property with recovery periods ranging from 3 years to 25 years.

How is the applicable recovery period determined?
Under §168(c), the “applicable recovery period” is determined by the recovery class of the property. Under §168(e), most personal property is placed in three-year, five-year, seven-year, 10-year, 15-year or 20-year classes. The 15-year and 20-year recovery classes generally include inherently permanent assets, such as land improvements. Most other real estate assets, such as buildings, are placed in the 27.5-year, 31.5-year, or 39-year recovery classes. Railroad grading and tunnel bores are placed in the 50-year category.
Under ACRS, most personal property is placed in the three-year, five-year, or 10-year recovery class, and most realty is placed in the 15-year, 18-year, 19-year, or low-income housing recovery class, depending on its nature and the date it was placed in service. The unadjusted basis of the asset (generally its cost) is recovered over the period reflected by its recovery class, although the taxpayer can elect a longer recovery period.

What is additional first-year depreciation (bonus depreciation)?
Under the bonus depreciation rules, a taxpayer may deduct in the property’s placed-in-service year, rather than capitalize and recover through MACRS, a percentage of the adjusted basis of qualified property. The adjusted basis of the property is reduced by the amount of this additional first-year depreciation (and by the amount of any first-year expensing under other code provisions, such as §179) before the MACRS deduction for the year in which the property is placed in service and subsequent years is computed.
