Rental Property Depreciation
Learn how to deduct building costs and improvements over 27.5 years—one of the most powerful tax benefits for real estate investors.
What is Rental Property Depreciation?
Rental property depreciation is a powerful tax deduction that allows property owners to claim an annual deduction for the wear and tear on their buildings and improvements. Under IRC Section 168(c), residential rental properties are depreciated over 27.5 years using the straight-line method. This means if you own a property with a $300,000 depreciable basis, you can deduct approximately $10,909 each year for 27.5 years—purely on the basis of ownership, regardless of whether the property actually declines in value.
The IRS recognizes that buildings deteriorate over time through normal use, weather exposure, and aging of systems. While this is technically a non-cash deduction (you're not actually paying money), it reduces your taxable rental income, which can be your ticket to significant tax savings. For many real estate investors, depreciation transforms what appears to be positive cash flow into a paper loss for tax purposes, dramatically reducing tax liability.
Understanding the Depreciation Concept
Depreciation is an allowance for the decline in value and utility of an asset. For rental properties, the IRS uses "useful life" to determine how many years an asset can provide economic benefit. Residential buildings have a useful life of 27.5 years under current tax law. This isn't based on when the building will actually become worthless—it's a standardized period set by Congress that applies equally to all residential rental properties.
The key distinction is between the building itself (depreciable) and the land (not depreciable). Land is considered to have an indefinite useful life and never depreciates. When you purchase a rental property, part of your purchase price goes to land and part goes to the building. Only the building portion can be depreciated. This allocation is critical because it determines your annual deduction amount.
Who Benefits Most from Rental Property Depreciation?
Rental property depreciation benefits a wide range of real estate investors, but certain situations make it particularly valuable:
- Individual landlords renting out single-family homes or multi-unit properties can reduce taxable income significantly
- Real estate investors building portfolios of rental properties benefit from compounding depreciation across multiple properties
- Business owners who convert commercial buildings to rentals can accelerate deductions through cost segregation studies
- High-income earners benefit most from passive loss deductions, especially those with sufficient passive income from other rentals
- Estate planners benefit from the stepped-up basis available at death, which resets depreciation
- Real estate syndicators can pass depreciation benefits through to limited partners
Step-by-Step Implementation Guide
Implementing rental property depreciation involves several critical steps. Follow this roadmap to ensure proper calculation and documentation:
Step 1: Determine Your Property's Adjusted Basis
Your adjusted basis is what you paid for the property plus any capital improvements, minus any depreciation you've already claimed. For a newly purchased property, this is your acquisition cost including:
- Purchase price (down payment plus any financed amount)
- Closing costs directly related to acquisition
- Property inspection fees
- Title insurance (some portions)
- Capital improvements made before the property is placed in service
Step 2: Allocate Between Land and Building
This is one of the most important steps. You must separate the land value from the building value. Methods include:
- County assessor records: Use the assessment ratio (land % vs. improvement %)
- Professional appraisal: Hire an appraiser to determine fair market values separately
- Cost segregation study: For larger properties, this detailed analysis breaks down components by depreciation period
Example: A property purchased for $500,000 with county assessor showing 25% land value:
- Land value: $500,000 × 0.25 = $125,000 (not depreciable)
- Building value: $500,000 × 0.75 = $375,000 (depreciable basis)
Step 3: Calculate Annual Depreciation Using Straight-Line Method
The formula is simple: Depreciable Basis ÷ 27.5 Years = Annual Depreciation Deduction
Example Calculation:
Building depreciable basis: $375,000
Useful life: 27.5 years
Annual depreciation: $375,000 ÷ 27.5 = $13,636 per year
Step 4: Add Capital Improvements
When you make capital improvements (not repairs), you can depreciate them. New depreciable components start fresh 27.5-year schedules from the date placed in service:
- Roof replacement: $25,000 → $909/year for 27.5 years
- HVAC system: $15,000 → $545/year for 27.5 years
- Kitchen renovation (capital): $40,000 → $1,455/year for 27.5 years
Step 5: Complete Form 4562 with Your Tax Return
File Form 4562 (Depreciation and Amortization) with your federal tax return. For rental property depreciation, use Part III of the form. Include:
- Property description and location
- Date placed in service
- Depreciable basis
- Recovery period (27.5 years)
- Method used (straight-line)
- Annual depreciation deduction
Real Numbers: Complete Rental Property Example
Let's walk through a real-world scenario to show how rental property depreciation works and impacts your taxes:
The Property
- Purchase price: $550,000
- County assessment: 30% land, 70% improvements
- Land value: $165,000
- Building value: $385,000
Year One Calculation
Building basis: $385,000
Annual depreciation: $385,000 ÷ 27.5 = $14,000
Improvements Added in Year 3
- New roof: $32,000 → $1,164/year
- HVAC system: $18,000 → $655/year
- Updated flooring: $12,000 → $436/year
Year 3 total depreciation: $14,000 + $1,164 + $655 + $436 = $16,255
Tax Impact
| Item | Year 1 | Year 3 |
|---|---|---|
| Rental income | $30,000 | $31,500 |
| Operating expenses | $12,000 | $12,500 |
| Mortgage interest | $16,000 | $15,500 |
| Depreciation deduction | $14,000 | $16,255 |
| Taxable income/(loss) | ($12,000) loss | ($12,755) loss |
| Actual cash flow (after mortgage) | +$2,000 positive | +$3,500 positive |
The result: You have positive cash flow for three years but report tax losses because of depreciation. At a 24% tax rate, the depreciation deduction saves you $3,360 in Year 1 and $3,901 in Year 3.
Expert Tax-Saving Strategies
Strategy 1: Cost Segregation Analysis
A professional cost segregation study breaks down property components into different depreciation periods. Instead of depreciating everything over 27.5 years, components like flooring, fixtures, and systems might depreciate over 5-15 years. This front-loads depreciation deductions significantly.
Example impact: A $500,000 building might generate $18,200 depreciation annually without cost segregation. With cost segregation, the first year might generate $35,000-$45,000 in depreciation deductions, with lesser amounts in subsequent years.
Cost: $1,500-$4,000 for the study. Best for: Properties over $1 million or multi-unit complexes.
Strategy 2: Bonus Depreciation for Improvements
Under IRC Section 168(k), certain property improvements may qualify for bonus depreciation, allowing 100% (2023-2024) or 80% (2025-2032) immediate deduction rather than spreading over 27.5 years.
Example: A $50,000 HVAC replacement might generate $50,000 depreciation in Year 1 instead of $1,818 annually. Check with a tax professional as qualification rules are complex.
Strategy 3: Stepped-Up Basis Planning
When you inherit a property, you receive a stepped-up basis to fair market value at death. Depreciation resets, allowing the heir to claim depreciation from this new higher basis. This is one of the most powerful tax benefits available.
Strategy 4: Separately Identifiable Components
For major improvements, identify separately depreciable components. Rather than one "kitchen renovation" lump sum, break it into: fixtures (5-7 years), cabinetry (15 years), countertops (27.5 years), etc. This may allow acceleration of some components.
Strategy 5: Document Everything Thoroughly
Keep detailed records of:
- Original purchase documents and appraisals
- Cost segregation studies
- Receipts for all capital improvements
- Depreciation schedules
- Before/after photos of improvements
- Contractor invoices clearly describing work performed
The IRS audit rate for rental property depreciation is low if properly documented, but high if records are missing.
Common Mistakes to Avoid
Mistake 1: Depreciating Land
This is the most common error. Land never depreciates because it doesn't wear out. If you depreciate land, the IRS will disallow the deduction and assess penalties. Always use professional valuation to allocate purchase price correctly.
Mistake 2: Confusing Repairs and Improvements
Repairs maintain the property's condition and cannot be depreciated (deductible in full in the year incurred). Improvements add value or extend useful life and must be depreciated. The IRS has specific threshold rules:
- Repairs under $2,500 can be expensed immediately
- Improvements over $2,500 typically must be capitalized and depreciated
- Component depreciation rules apply to components built together
Mistake 3: Missing the Placed-in-Service Date
Depreciation begins the date the property is actually ready for rental use, not the purchase date. If you purchased on January 15 but didn't complete renovations until July 1, depreciation starts July 1. Getting this wrong can result in multiple years of audit adjustments.
Mistake 4: Failing to Claim Depreciation
Interestingly, the IRS requires you to claim depreciation on rental properties. Even if you don't claim it, when you sell the property, you owe depreciation recapture tax on the full amount you could have deducted. You cannot avoid this tax by failing to claim depreciation.
Mistake 5: Improper Land/Building Allocation
Using a rough estimate instead of proper valuation can result in excessive depreciation claims. Use county assessor records at minimum; for significant properties, get a professional appraisal. An improper allocation can trigger an audit.
Mistake 6: Claiming Depreciation on Non-Rental Properties
Your personal residence, vacation home, or property held purely as land investment cannot be depreciated. Only properties actively rented or held for rental income qualify.
Depreciation Compared to Other Tax Strategies
Rental property depreciation works alongside other tax strategies. Here's how it compares:
| Strategy | Depreciation Period | Tax Rate | When Used |
|---|---|---|---|
| Straight-Line Depreciation (Buildings) | 27.5 years | 15-25% recapture | All residential rentals |
| Cost Segregation | 5-15 years (components) | 15-25% recapture | Large properties ($1M+) |
| Bonus Depreciation | 100% Year 1 (improvements) | 15-25% recapture | Property improvements |
| Section 179 Deduction | Immediate expensing | No recapture (ordinary) | Personal property, vehicles |
| Mortgage Interest Deduction | Annual deduction | None (no recapture) | All leveraged properties |

Frequently Asked Questions
Rental property depreciation is a non-cash tax deduction that allows property owners to deduct the cost of a rental building and its improvements over 27.5 years. The IRS assumes buildings lose value through wear and tear, and lets owners claim annual deductions based on the property's depreciable basis divided by the useful life.
Residential rental property is depreciated over 27.5 years using the straight-line method under IRC Section 168(c). This is the recovery period established by the IRS for residential buildings placed in service after 1986. Commercial properties have a 39-year depreciation period.
No. Land cannot be depreciated because it does not wear out or deteriorate over time. You must allocate your purchase price between land and building. Only the building portion and certain improvements are depreciable. Land has an indefinite useful life under tax law.
Depreciable improvements include roof replacement, HVAC systems, flooring, fixtures, appliances, and structural components. Repairs maintain the property's condition and are not depreciated. Capital improvements add value or extend the property's life and can be depreciated over their useful lives.
Use the straight-line method: Depreciable Basis ÷ 27.5 Years = Annual Depreciation Deduction. Depreciable basis equals the property's cost basis minus the land value. For example, a $400,000 property with $100,000 land value has a $300,000 building basis, yielding $10,909 annual depreciation.
Bonus depreciation (IRC Section 168(k)) allows deduction of a percentage of qualified property cost immediately. For 2024, bonus depreciation is 60% for improvements. However, buildings themselves still use the 27.5-year schedule, but certain property improvements may qualify for accelerated depreciation under bonus rules.
Cost segregation is an analysis that breaks down property components into different depreciation schedules. Building elements like HVAC, electrical, and flooring might depreciate over 5-15 years instead of 27.5 years, accelerating deductions significantly for investors in larger properties.
Yes. IRC Section 1250 requires recapture of all straight-line depreciation at a 25% tax rate when you sell residential rental property. If you depreciated $100,000, you'll owe approximately $25,000 in recapture tax when selling, in addition to capital gains tax on the property appreciation.
No. Only properties held for business or investment purposes qualify for depreciation. A personal residence, vacation home you use yourself, or property held primarily as land cannot claim depreciation deductions. The property must generate rental income to qualify.
Use the property's assessed values or a professional appraisal as your basis. Typical allocations range from 20-40% land value in urban areas to 5-20% in commercial districts. County assessor records provide a reasonable starting point for allocation percentages.
Keep the original purchase contract, appraisal or cost segregation study, bank statements, receipts for capital improvements, and a depreciation schedule showing annual calculations. Form 4562 (Depreciation and Amortization) must be filed with your tax return each year.
Yes. Capital improvements like new roofs, HVAC systems, or appliances are depreciated over their useful lives starting from the date they are placed in service. Repairs that merely maintain the property cannot be depreciated. The improvement must add value or extend the property's useful life.
You get a stepped-up basis in inherited property, resetting depreciation. You use the fair market value on the date of death as the new basis for depreciation calculations, allowing you to claim depreciation from that higher starting point without recapture liability on prior years.
Depreciation is required to be claimed on rental properties for tax purposes. Even if you don't claim it, the IRS assumes you could have and will require recapture on the full amount when you sell, whether or not you actually deducted it on your tax returns.
Depreciation reduces your adjusted basis in the property. If you buy for $300,000 and depreciate $50,000, your basis becomes $250,000 for capital gains calculation. This increases capital gains when you sell, as you'll owe taxes on the depreciation recapture in addition to long-term capital gains tax.
