What Is Rental Property Depreciation?
Rental property depreciation is a tax deduction that allows rental property owners to recover the cost of their investment property over time. The IRS recognizes that buildings lose value as they age due to wear and tear, weathering, and general obsolescence. Depreciation lets you deduct a portion of the property's cost from your rental income each year, reducing your taxable income even if the property is actually appreciating in market value.
This is one of the most powerful tax advantages of owning rental real estate. Unlike most tax deductions, depreciation is a "paper loss" -- it reduces your taxes without requiring you to spend any additional money. You can claim depreciation every year for 27.5 years on residential rental property, regardless of whether the property's market value is going up or down.
For example, if you own a rental property with a building value of $240,000, you can deduct approximately $8,727 per year in depreciation. If you're in the 25% tax bracket, that translates to roughly $2,182 in annual tax savings -- money that stays in your pocket simply because you own the property.
IRS Rules for Rental Property Depreciation
The IRS has specific rules governing how rental property depreciation works. Understanding these rules is essential for claiming the correct deduction and avoiding issues with the IRS.
The 27.5-Year Recovery Period
Residential rental property must be depreciated over 27.5 years using the straight-line method. This means you deduct an equal amount each year (except for the first and last years, which are prorated). The 27.5-year period applies to the building and any structural components -- things like walls, floors, roofing, plumbing, electrical systems, and HVAC that are part of the building itself.
Straight-Line Method
The straight-line method is the simplest form of depreciation. You take the depreciable basis (building value) and divide it by 27.5 years to get your annual deduction. Unlike accelerated depreciation methods used for other types of property, residential rental property must use straight-line depreciation.
Mid-Month Convention
The IRS requires the "mid-month convention" for residential rental property. This means that regardless of when during a month you place the property in service, it is treated as if it was placed in service at the midpoint of that month. So if you close on a rental property on January 3rd, the IRS treats it as if you started on January 15th. This affects your depreciation deduction in the first and last years of the recovery period.
What Qualifies for Depreciation
To claim depreciation on a rental property, it must meet all of these criteria:
- You own the property (you cannot depreciate property you rent from someone else)
- You use the property in your business or income-producing activity (rental use qualifies)
- The property has a determinable useful life (buildings deteriorate over time)
- The property is expected to last more than one year
Land is never depreciable because it does not wear out. This is why you must separate the land value from the building value when calculating depreciation.
How to Calculate Depreciation
Calculating depreciation for residential rental property is straightforward once you know the formula. Here is a step-by-step walkthrough with an example.
Step 1: Determine Your Cost Basis
Your cost basis is typically the purchase price of the property plus certain closing costs (such as title fees, recording fees, and transfer taxes). For simplicity, most investors start with the purchase price. In our example, let's say you purchased a rental property for $300,000.
Step 2: Separate Land Value from Building Value
Since land cannot be depreciated, you need to determine what portion of the purchase price is attributable to the land versus the building. In our example, if the land is worth 20% of the total, the building value is $300,000 x 0.80 = $240,000, and the land value is $300,000 x 0.20 = $60,000.
Step 3: Calculate Annual Depreciation
Divide the building value by 27.5 years: $240,000 / 27.5 = $8,727.27 per year. This is the amount you can deduct from your rental income each full year.
Step 4: Prorate the First Year
Using the mid-month convention, if you purchased the property in March, you get credit for 9.5 months of depreciation in the first year (mid-March through December). The first-year deduction would be: $8,727.27 x (9.5 / 12) = $6,909.09.
Step 5: Claim the Deduction
Report your depreciation deduction on IRS Schedule E (Form 1040), Line 18. RentFolio's built-in Schedule E export can calculate and fill this value for you automatically.
Land Value vs. Building Value
Separating the land value from the building value is one of the most important steps in calculating depreciation, and it's where many property owners get confused. Here are several methods the IRS considers acceptable:
Property Tax Assessment
The most common method is to use your local property tax assessment, which typically breaks out the assessed value into land and improvements (building). Calculate the percentage of total assessed value attributed to land, then apply that percentage to your purchase price. For example, if your tax assessment shows $50,000 for land and $200,000 for improvements, the land represents 20% of the total assessed value.
Appraisal
A professional appraisal that separates land and building values is another accepted method. While more expensive, it provides a defensible allocation if the IRS ever questions your depreciation calculations.
Comparable Sales
You can also look at comparable land sales in your area to estimate the land value, then subtract that from the purchase price to arrive at the building value. This method works best in areas with active lot sales.
Whichever method you choose, be consistent and keep documentation supporting your allocation. The IRS may challenge an unreasonably low land value percentage since a lower land value means a higher building value and larger depreciation deductions.
Depreciation and Schedule E
Depreciation is reported on IRS Form 1040 Schedule E, which is the form used to report income and expenses from rental real estate. Your depreciation deduction appears on Line 18 of Schedule E.
Depreciation is a significant line item on Schedule E and can make the difference between showing a taxable profit or a paper loss on your rental property. Combined with other deductible expenses like mortgage interest, insurance, repairs, and property management fees, depreciation often allows landlords to show a loss on paper even when the property generates positive cash flow.
Tracking depreciation accurately across multiple properties and multiple years can become complex. RentFolio's Schedule E export feature automatically maps your income and expenses to the correct Schedule E line items, including depreciation, making tax filing significantly easier. Instead of manually compiling spreadsheets at tax time, you can generate a complete Schedule E report with a few clicks.
If your rental losses exceed your rental income, you may be able to deduct up to $25,000 in losses against your other income if your modified adjusted gross income (MAGI) is under $100,000 and you actively participate in the rental activity. This deduction phases out between $100,000 and $150,000 MAGI.
Depreciation Recapture: What to Know When You Sell
One important aspect of depreciation that property owners should understand before they sell is depreciation recapture. When you sell a rental property for more than its depreciated value (which is almost always the case), the IRS requires you to "recapture" the depreciation you claimed over the years.
Depreciation recapture is taxed at a maximum rate of 25%, which is separate from and in addition to any capital gains tax you might owe on the sale. The recaptured amount is the total depreciation you claimed (or were allowed to claim, even if you didn't take it) during the time you owned the property.
For example, if you claimed $87,273 in total depreciation over 10 years and then sold the property, you would owe depreciation recapture tax on that $87,273 at up to 25%, plus capital gains tax on any additional profit above your adjusted basis.
This does not mean you should skip claiming depreciation. The IRS calculates recapture based on the depreciation you were allowed to take, whether or not you actually claimed it. So failing to take depreciation deductions means you lose the annual tax benefit but still owe recapture tax when you sell. Always claim your depreciation.
A 1031 exchange can defer depreciation recapture tax by rolling the proceeds into a like-kind replacement property. Many investors use this strategy to defer taxes indefinitely across multiple properties over their investing career.
Common Depreciation Mistakes to Avoid
Even experienced landlords sometimes make errors with depreciation. Here are the most common pitfalls and how to avoid them:
1. Depreciating the Land
Land never depreciates. If you forget to separate the land value and depreciate the full purchase price, you're overstating your deduction. The IRS can disallow the excess and assess penalties.
2. Not Claiming Depreciation at All
Some landlords skip depreciation because they think it will save them from recapture tax when they sell. This is a mistake. The IRS calculates recapture based on allowable depreciation regardless of whether you claimed it. You'll owe the recapture tax either way, so you should always take the deduction.
3. Using the Wrong Recovery Period
Residential rental property uses 27.5 years. Commercial property uses 39 years. Land improvements (fences, driveways, landscaping) use 15 years. Mixing these up leads to incorrect deductions. If your property is mixed-use, you may need to allocate the cost across different recovery periods.
4. Starting Depreciation Too Early
You can only begin depreciating a rental property when it is "placed in service" -- meaning it's ready and available for rent. If you buy a property and spend six months renovating it before listing it for rent, depreciation starts when it's ready for tenants, not when you closed on the purchase.
5. Forgetting About Improvements
Capital improvements (a new roof, kitchen remodel, HVAC replacement) must be depreciated separately from the original building. Each improvement starts its own 27.5-year depreciation clock. Repairs (fixing a leaky faucet, patching drywall) are expensed immediately and are not depreciated.
6. Incorrect Land Value Allocation
Using an unreasonably low land value to inflate your building value and depreciation deductions is a red flag for the IRS. Base your allocation on objective evidence like tax assessments or appraisals, and keep documentation to support your numbers.
