MACRS Depreciation Formula:
| From: | To: |
The Modified Accelerated Cost Recovery System (MACRS) is the current tax depreciation system in the United States. It allows businesses to recover the cost of income-producing property over time through annual tax deductions.
The calculator uses the MACRS formula:
Where:
Explanation: The MACRS system assigns different depreciation rates based on asset class and recovery period (3, 5, 7, 10, 15, 20, 27.5, or 39 years).
Details: Proper depreciation calculation is essential for accurate tax reporting, financial statements, and business planning. MACRS provides accelerated depreciation compared to straight-line methods.
Tips: Enter the original cost of the asset and the appropriate MACRS rate for the asset's class and recovery year. The MACRS rate should be a decimal between 0 and 1.
Q1: Where can I find MACRS rates?
A: MACRS rates are published by the IRS in Publication 946. Different rates apply depending on the asset class and recovery year.
Q2: What's the difference between GDS and ADS under MACRS?
A: GDS (General Depreciation System) uses shorter recovery periods and accelerated methods, while ADS (Alternative Depreciation System) uses longer periods and straight-line.
Q3: Can I use MACRS for all business assets?
A: Most tangible property used in business can use MACRS, but some assets like land, inventory, and intangible property cannot be depreciated.
Q4: How does the half-year convention work?
A: The half-year convention assumes assets are placed in service mid-year, giving a half-year's depreciation in the first year regardless of actual purchase date.
Q5: Can I switch depreciation methods later?
A: Generally no - once you elect MACRS for an asset, you must continue using it unless you get IRS permission to change.
