A recovery period is the tax span used to depreciate property. Learn common MACRS periods, GDS versus ADS, conventions, and California differences.
A recovery period is the number of years over which a taxpayer recovers depreciable basis under an applicable tax depreciation system. Under MACRS, the correct period depends on the property class and whether the General Depreciation System (GDS) or Alternative Depreciation System (ADS) applies. It is not simply how long the owner expects the asset to last.
The recovery period is only one input. The depreciation method and convention also affect the annual deduction, and Section 179 or bonus depreciation may recover some qualifying basis earlier.
GDS commonly places assets into 3-, 5-, 7-, 10-, 15-, or 20-year personal-property classes. Examples often include computers and certain equipment as five-year property, office furniture as seven-year property, and certain land improvements as fifteen-year property. These are general examples; the activity-specific asset-class tables in Publication 946 can override a casual description.
| Common property type | GDS recovery period | Method |
|---|---|---|
| Computers and certain equipment | 5 years | 200% DB / SL |
| Office furniture and fixtures | 7 years | 200% DB / SL |
| Certain land improvements | 15 years | 150% DB / SL |
| Residential rental property | 27.5 years | Straight line |
| Nonresidential real property | 39 years | Straight line |
Qualified improvement property generally has a 15-year GDS recovery period when the statutory requirements are met. ADS often uses longer periods and straight-line depreciation. Publication 946 should be used to classify the actual property rather than relying on a generic online list.
Start by confirming that the amount must be capitalized and that the property is depreciable. Then identify the asset and the business activity. Publication 946's Appendix B contains asset classes and recovery periods. A specifically described asset class may control; otherwise an activity class may apply.
Next determine whether GDS or ADS is required or elected. Identify the placed-in-service date, method, and convention. Listed-property rules, business-use percentages, real-property elections, and special industry rules can change the result.
An asset name alone is not always enough. A cash register used in retail can fall under an activity class, while office furniture may remain in a general asset class. Improvements must be analyzed separately from the building or land to which they relate.
Coastal Design LLC estimates that its $42,000 machine will provide six years of economic benefit. Federal classification instead places it in a five-year GDS class. Five-year property does not necessarily produce exactly one-fifth of basis as a deduction in each of five calendar years because accelerated methods and conventions affect timing.
If Coastal elects or is required to use ADS, a different recovery period and straight-line method may apply. If the machine qualifies for bonus depreciation, eligible basis can be deducted before regular MACRS is computed. "Five-year property" does not automatically mean five equal annual deductions.
The recovery period describes the statutory span. The convention determines when property is treated as placed in service and disposed of within the tax year for depreciation calculations.
The half-year convention generally treats qualifying personal property as placed in service or disposed of at the midpoint of the year. The mid-quarter convention can apply when more than 40% of the aggregate basis of applicable property is placed in service during the last three months of the year. Real property generally uses the mid-month convention.
These conventions can cause deductions to extend into an additional tax year beyond the number printed in the class name. They do not change the underlying recovery period.
GDS is the more common MACRS system and often uses accelerated depreciation for personal property. ADS generally uses straight line over an ADS recovery period. ADS can be required for certain property, including some property used predominantly outside the United States, tax-exempt-use property, tax-exempt-bond-financed property, and property of an electing real property or farming trade or business, subject to detailed rules.
An ADS election can have long-term consequences and may apply by class. Do not switch systems merely to reach a preferred deduction without documenting the governing rule and election.
California depreciation can differ because the state does not conform to every federal accelerated deduction, limit, or election. California does not conform to federal bonus depreciation. A federal basis reduced by a large bonus deduction can therefore differ sharply from California basis, creating different later-year depreciation and disposition results.
Use the applicable FTB depreciation form and return instructions for the taxpayer's entity and activity. Maintain asset-level federal and California records showing cost, adjustments, recovery period, method, prior depreciation, and remaining basis.
Heath Income Tax can help classify property and maintain the separate federal and California depreciation schedules a business needs.
Is a recovery period the same as useful life?
No. Useful life is generally an economic or accounting estimate. The tax recovery period is prescribed by the applicable depreciation rules.
Why can five-year property have deductions in six tax years?
The half-year convention can create a partial deduction in the first and final years. The class remains five-year property.
Does bonus depreciation change the recovery period?
No. Bonus depreciation reduces eligible basis before regular depreciation. Any remaining basis is still recovered using the applicable MACRS rules.
