📋 MACRS: The US Tax Depreciation Powerhouse
MACRS (Modified Accelerated Cost Recovery System) is the US tax depreciation method — 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.
💡 Did You Know?
📖 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-loaded—more in early years.
Half-Year Convention
Assumes property placed in service mid-year. Used for 3–20 year property.
Mid-Month Convention
Used for 27.5 and 39-year real property. Depends on month placed in service.
🎯 Expert Tips
Section 179 / Bonus
Consider Section 179 or bonus depreciation for qualifying assets—may 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.

❓ Frequently Asked Questions
What is MACRS depreciation?
MACRS (Modified Accelerated Cost Recovery System) is the US tax depreciation method mandated by the IRS. 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. It uses fixed percentage tables from IRS Publication 946.
What are MACRS recovery periods?
MACRS recovery periods: 3-year (tractor units), 5-year (computers, vehicles, equipment), 7-year (office furniture, machinery), 10-year, 15-year, 20-year for personal property. Real property: 27.5-year for residential rental, 39-year for commercial. Each class uses IRS percentage tables.
MACRS vs straight-line depreciation?
MACRS front-loads deductions—more in early years, less later. Straight-line spreads depreciation evenly. A $50K 5-year asset: MACRS Yr1=$10K, Yr2=$16K vs straight-line $10K each year. MACRS accelerates tax savings but both methods depreciate 100% of cost.
Section 179 vs MACRS?
Section 179 allows up to $1.16M (2024) immediate deduction for qualifying equipment—deduct the full cost in year 1. MACRS spreads depreciation over 5-7+ years. For $100K equipment: Section 179 = $100K deduction in Yr1; MACRS = spread over 5-7 years. Section 179 is elective and has limits.
What is the MACRS depreciation table?
IRS MACRS tables (Publication 946) provide fixed percentages by year. 5-year half-year: 20%, 32%, 19.2%, 11.52%, 11.52%, 5.76%. 7-year: 14.29%, 24.49%, 17.49%, 12.49%, 8.93%, 8.92%, 8.93%, 4.46%. Multiply asset cost by the percentage for each year.
What is the half-year convention?
The half-year convention assumes property is placed in service mid-year. Only half a year's depreciation in year 1 and the last year. Used for 3-20 year personal property. 5-year property actually depreciates over 6 tax years. Real property uses mid-month convention instead.
