๐ MACRS: The US Tax Depreciation Powerhouse
MACRS (Modified Accelerated Cost Recovery System) is the US tax depreciation method โ it front-loads deductions so businesses get bigger tax breaks in early years. A $50K vehicle depreciates 20% in year 1 and 32% in year 2 under 5-year MACRS. Section 179 allows up to $1.16M (2024) in IMMEDIATE deduction. Bonus depreciation allows 80% (2024) first-year deduction on new assets. Real estate is stuck at 27.5 years (residential) or 39 years (commercial). MACRS uses the half-year convention: only half a year's depreciation in years 1 and last.
๐ก Did You Know?
๐ How MACRS Works
IRS provides fixed percentage tables. Multiply asset cost by the percentage for each year. No salvage value reduction for MACRS. Depreciation is front-loadedโmore in early years.
Half-Year Convention
Assumes property placed in service mid-year. Used for 3โ20 year property.
Mid-Month Convention
Used for 27.5 and 39-year real property. Depends on month placed in service.
๐ฏ Expert Tips
Section 179 / Bonus
Consider Section 179 or bonus depreciation for qualifying assetsโmay allow 100% first-year deduction.
Placement Timing
Placing property in service earlier in the year can increase first-year depreciation under mid-month.
Tax Rate Impact
Higher tax rate = higher tax savings from depreciation. Use your marginal rate for estimates.
Personal vs Business
MACRS is for business/investment property. Personal-use assets use different rules.
