Modified Accelerated Cost Recovery System
Note: MACRS typically assumes $0 salvage value, but you can enter an estimated value
About MACRS Depreciation MACRS (Modified Accelerated Cost Recovery System) is the primary method used to determine depreciation deductions for U.S. federal income tax purposes.
Depreciation Methods:
- 200% Declining Balance (GDS): 200% Declining Balance (GDS): Provides the highest tax deductions in the early years
- 150% Declining Balance (GDS): 150% Declining Balance (GDS): Provides higher deductions than straight-line but lower than the 200% method
- Straight Line (SL): Straight Line (SL): Deducts the same amount each year (except the first and last year)
Recovery Period Examples:
- 3-year: Certain tractors, horses
- 5-year: Automobiles, computers, office equipment
- 7-year: Office furniture, agricultural machinery
- 27.5-year: Residential rental real estate
- 39-year: Nonresidential real estate
About Salvage Value: Under MACRS rules, depreciation calculations typically assume a salvage value of $0. However, this calculator allows you to enter an estimated salvage value to more accurately reflect the asset's actual value. When a salvage value is entered, depreciation will stop when the book value reaches the salvage value.
