How Rental Property Depreciation Works
The IRS recognizes that buildings deteriorate over time. Depreciation is a tax deduction that accounts for this wear and tear, even though your property may actually be appreciating in market value. It is one of the unique advantages real estate has over other investments.
The Basics
- Residential rental property: 27.5 years, straight-line method
- Commercial property: 39 years, straight-line method
- Land: Never depreciable (land does not wear out)
- Personal property in the rental: 5 or 7 years (appliances, furniture)
- Land improvements: 15 years (fencing, parking, landscaping)
Straight-Line Depreciation Example
You buy a rental house for $350,000. The land is worth $70,000.
Purchase price: $350,000
Less land value: ($70,000)
Depreciable basis: $280,000
Annual depreciation: $280,000 / 27.5 = $10,182
That $10,182 annual deduction costs you nothing out of pocket. It is purely a paper expense that reduces your taxable rental income every year for 27.5 years.
When Depreciation Begins
Depreciation starts when the property is placed in service, meaning it is available and ready to rent. This is not necessarily the purchase date. If you buy in January and spend two months renovating before listing it for rent, depreciation starts in March.
The IRS uses the mid-month convention for real property. Regardless of the actual day you place the property in service, you are treated as if it was placed in service at the midpoint of that month.
Non-Cash Benefit
Depreciation is a "phantom expense." You do not write a check. It reduces your taxable income without reducing your cash flow. A property that breaks even on cash flow can still generate a significant tax loss after depreciation, putting money back in your pocket through lower taxes.
Calculating Your Depreciable Basis
Getting the basis right is critical. It determines your annual depreciation deduction for the next 27.5 years and affects your gain calculation when you sell.
Step 1: Start With the Purchase Price
Your starting point is the total amount you paid for the property, including the down payment, mortgage amount, and any seller concessions that reduced the price.
Step 2: Add Qualifying Closing Costs
Certain closing costs are added to basis (they increase your depreciable amount):
- Title insurance
- Attorney/legal fees
- Recording fees
- Transfer taxes
- Survey costs
- Title search fees
Costs that are NOT added to basis:
- Mortgage origination fees (amortized over the loan term)
- Prepaid interest / points (deducted or amortized separately)
- Property insurance premiums (annual operating expense)
- Property tax prorations (deducted as taxes in year paid)
Step 3: Subtract Land Value
Land is not depreciable. You must allocate a portion of the purchase price to land. Common methods:
- County tax assessment ratio: If the county assesses land at 20% of total value, allocate 20% to land.
- Appraisal: A qualified appraisal can separately value the land and improvements.
- Comparable land sales: Research recent vacant land sales in the area.
Complete Example
| Item | Amount |
|---|---|
| Purchase price | $400,000 |
| + Title insurance | $2,200 |
| + Attorney fees | $1,500 |
| + Recording fees | $300 |
| = Total cost basis | $404,000 |
| - Land allocation (20%) | ($80,800) |
| = Depreciable basis | $323,200 |
| Annual depreciation | $11,753 |
Improvements vs. Repairs
This distinction determines whether you deduct the cost immediately (repair) or capitalize and depreciate it over time (improvement). Getting it wrong can trigger an audit or cause you to miss deductions.
Repairs (Deducted Immediately)
A repair restores the property to its ordinary operating condition without adding significant value, extending its life, or adapting it to a new use.
- Fixing a leaky faucet or running toilet
- Patching drywall or repainting a room
- Replacing a broken window pane
- Fixing a garbage disposal
- Repairing a fence section
- Unclogging a drain
- Replacing a light switch or outlet
Improvements (Capitalized and Depreciated)
An improvement betters the property, restores it to like-new condition, or adapts it to a new use. These are capitalized and depreciated.
- New roof ($8,000-$15,000+)
- HVAC replacement ($5,000-$12,000)
- Kitchen or bathroom remodel
- Adding a room or converting a garage
- New flooring throughout the property
- New appliance package
- Complete plumbing or electrical system replacement
The IRS Safe Harbor Rules
The IRS provides safe harbor rules under the tangible property regulations (Treas. Reg. 1.263(a)) to help draw the line:
- De minimis safe harbor: Items costing $2,500 or less per invoice (or $5,000 with an applicable financial statement) can be expensed immediately regardless of whether they are technically improvements. Elect this annually on your tax return.
- Routine maintenance safe harbor: Recurring activities you expect to perform more than once during the property's life (servicing HVAC, exterior painting, general maintenance) can be expensed as repairs.
- Small taxpayer safe harbor: If your gross receipts are $10M or less and total improvements to a building are under the lesser of $10,000 or 2% of the building's basis, you can expense all of them.
Gray Area: Roof Repair vs. Replacement
Patching a small section of a roof is a repair. Replacing the entire roof is an improvement. But what about replacing 30% of the roof? The IRS looks at the "unit of property" (the entire building system, e.g., the roof system). If you replace a major component of a building system, it is likely an improvement. When in doubt, document your reasoning and consult your CPA.
Pro Tip: Partial Asset Dispositions
When you replace an improvement (old roof to new roof), you can elect a partial asset disposition under Treas. Reg. 1.168(i)-8. This lets you write off the remaining undepreciated value of the old component in the year of replacement. Most landlords miss this, losing thousands in deductions.
