Definition
The General Depreciation System (GDS) is the dominant method used by taxpayers for calculating depreciation of assets for tax purposes under the Modified Accelerated Cost Recovery System (MACRS). GDS permits taxpayers to depreciate property using the declining-balance method, transitioning to the straight-line method as it proves more advantageous, over predefined recovery periods that are generally shorter than those allowed under previous systems.
Examples
- Office Furniture - Office furniture under GDS is typically depreciated using a 7-year recovery period.
- Computers and Peripheral Equipment - Under GDS, these items are generally depreciated over a 5-year recovery period.
- Residential Rental Property - This type of property is typically depreciated over a 27.5-year recovery period when using GDS.
Frequently Asked Questions
What is the principal difference between GDS and ADS?
The primary difference between GDS (General Depreciation System) and ADS (Alternative Depreciation System) lies in the recovery periods; GDS usually provides faster depreciation through shorter recovery periods compared to ADS, resulting in higher depreciation deductions in the initial years.
How do I determine the correct recovery period for my asset under GDS?
The IRS provides detailed tables in Publication 946 that list the applicable recovery periods for different types of property under GDS.
Can I switch from GDS to ADS during the asset’s recovery period?
No, switching from GDS to ADS or vice versa, after having begun to depreciate an asset, is generally not permissible unless mandated by specific IRS regulations or special circumstances.
Is the declining-balance method always used throughout the entire recovery period under GDS?
No, the declining-balance method is often used until it provides a lower depreciation amount than the straight-line method, at which point a switch to the straight-line method occurs.
