MACRS (Modified Accelerated Cost Recovery System) is the depreciation method most business equipment uses after Section 179 and bonus depreciation are taken. MACRS is the default IRS method for property placed in service after 1986.
How MACRS works
MACRS assigns each asset a recovery period based on its property class:
- 3-year property: certain manufacturing tooling, racehorses
- 5-year property: computers, office equipment, trucks, trailers, certain agricultural equipment
- 7-year property: office furniture, fixtures, most other equipment without a specific class
- 10-year property: single-purpose agricultural structures, certain water transportation
- 15-year property: qualified improvement property, certain land improvements
- 20-year property: farm buildings (non-residential), municipal sewers
Depreciation methods within MACRS
200% declining balance: default for 3, 5, 7, and 10-year property. Larger deductions in early years, smaller in later years.
150% declining balance: default for 15 and 20-year property. Also elected for shorter classes if the business prefers slower depreciation.
Straight-line: election available for any class. Equal deduction each year.
The half-year convention
MACRS uses a half-year convention: in the year of acquisition and the year of disposition, the equipment gets a half-year of depreciation regardless of when in the year it was placed in service or disposed.
The exception is the mid-quarter convention: if more than 40% of total annual equipment purchases occur in the last quarter, all that year’s equipment uses mid-quarter convention instead.
Section 179 + bonus + MACRS order
Most equipment buyers apply deductions in this order:
- Section 179 up to cap and taxable income limit
- Bonus depreciation at current-year rate (60% in 2026)
- MACRS on the remaining basis over the recovery period
How financing affects MACRS
Financing does not change MACRS. You depreciate the equipment basis (purchase price + capitalized soft costs) regardless of whether you paid cash or financed.
