Why depreciation matters for rental property owners
Depreciation is one of the largest tax deductions available to landlords, and most new rental property owners don't realize how valuable it is until they see their first Schedule E.
The IRS allows you to deduct 1/27.5 of your building's value every year as a "wear and tear" expense—even if the property is appreciating in market value. It's a paper deduction that lowers your taxable income without requiring you to write a check.
Example: If your rental property's depreciable basis is $220,000, you deduct $8,000 per year for 27.5 years. That $8,000 reduces your taxable rental income annually, potentially saving you thousands in taxes depending on your bracket.
The Residential Depreciation Calculator helps you calculate your annual depreciation deduction in under a minute.
What you need before you start
To use the calculator, you need two numbers:
- Property Purchase Price — The total amount you paid for the property, including the building and land.
- Land Value — The portion of the purchase price that represents land (which cannot be depreciated).
Finding your land value
Land cannot be depreciated because the IRS considers it to have an indefinite useful life. Most properties have 15-25% of the purchase price allocated to land, though this varies significantly by location (urban lots may be 40%+; rural acreage may be 5-10%).
Here's how to determine your land value:
Option 1: Property tax assessment
Most county tax assessors separate land value from building value on your property tax bill or online assessment record. Search "[your county] property tax assessor" and look up your property's assessed value breakdown.
Example: - Total assessed value: $280,000 - Land assessed value: $56,000 (20%) - Building assessed value: $224,000 (80%)
If your purchase price was $300,000, you would allocate 20% to land: $300,000 × 0.20 = $60,000 land value.
Option 2: Appraisal
If you had an appraisal done for financing, the appraiser may have separated land and improvement values. Check the appraisal report or ask your lender for a copy.
Option 3: Professional allocation
Your accountant or a qualified appraiser can determine the land-to-building ratio based on comparable sales, local assessment records, or appraisal data. This is especially important for high-value properties or if the tax assessment seems misaligned with market conditions.
Using the calculator: step-by-step
Let's walk through a real example using the Residential Depreciation Calculator.
Example scenario
You purchased a rental property for $300,000. Based on your county tax assessment, land represents 20% of the value, or $60,000. The building value is $240,000.
Step 1: Enter your purchase price
In the Property Purchase Price field, enter 300000 (or 300000.00). This is the total amount you paid for the property.
Step 2: Enter your land value
In the Land Value field, enter 60000 (or 60000.00). This is the portion of the purchase price that cannot be depreciated.
The calculator provides a hint: "Land cannot be depreciated (typically 15-25% of purchase price)." If your land value is significantly outside this range, double-check your assessment or consult with your accountant.

Step 4: Review your results
The calculator displays:
- Purchase Price: $300,000.00
- Land Value (not depreciable): $60,000.00
- Depreciable Basis: $240,000.00
- Depreciation Period: 27.5 years
And the key result:
Annual Depreciation Deduction (Schedule E Line 18): $8,727.27
This is the amount you will deduct on Schedule E Line 18 each year for the next 27.5 years (subject to partial-year adjustments in your first and last years of ownership).
The calculator also shows:
- Monthly Depreciation: $727.27 (useful for mid-year purchases or partial-year calculations)
- 10-Year Depreciation Schedule showing accumulated depreciation and remaining basis over time
Understanding the calculation
The formula is straightforward:
Depreciable Basis = Purchase Price − Land Value
- $300,000 − $60,000 = $240,000
Annual Depreciation = Depreciable Basis ÷ 27.5 years
- $240,000 ÷ 27.5 = $8,727.27
That $8,727.27 is your annual depreciation deduction for Schedule E Line 18.
Why 27.5 years?
The IRS classifies residential rental property as having a 27.5-year recovery period under the Modified Accelerated Cost Recovery System (MACRS). This is a straight-line depreciation method—the same amount each year.
Commercial property uses a 39-year schedule. Appliances, carpeting, and furniture (if you rent furnished) may be depreciated over 5 or 7 years. But the building structure itself is 27.5 years for residential rentals.
What the depreciation schedule tells you
The calculator provides a 10-Year Depreciation Schedule that shows:
- Year — The year of ownership
- Annual Depreciation — The amount deducted each year ($8,727.27 in our example)
- Accumulated Depreciation — The total depreciation claimed to date
- Remaining Basis — The adjusted basis of the property after depreciation
Why this matters
Your adjusted basis (original basis minus accumulated depreciation) is used when you sell the property:
- It determines your taxable gain: Sale Price − Adjusted Basis = Gain
- The accumulated depreciation is subject to depreciation recapture tax at up to 25% when you sell
Example: After 10 years, you've claimed $87,272.70 in depreciation. If you sell for $400,000:
- Adjusted basis: $300,000 − $87,272.70 = $212,727.30
- Total gain: $400,000 − $212,727.30 = $187,272.70
- Depreciation recapture (taxed at 25%): $87,272.70
- Capital gain (taxed at 0%, 15%, or 20%): $100,000

Reporting depreciation on Schedule E
Your annual depreciation deduction is reported on IRS Form 1040, Schedule E (Supplemental Income and Loss), Line 18 — Depreciation expense.
The first year you claim depreciation, you must also complete Form 4562 (Depreciation and Amortization) to document your depreciable assets and method. In subsequent years, if you're only depreciating the same property with no new additions, many tax software programs allow you to carry forward the depreciation without re-filing Form 4562.
ManorKeeper's accounting system tracks the "Depreciation" category aligned with Schedule E Line 18, making it simple to see your annual deduction at a glance.

Common questions and edge cases
What if I made capital improvements after purchase?
Capital improvements—like a new roof, HVAC system, or kitchen remodel—increase your depreciable basis and are depreciated separately. The building's original basis continues on its 27.5-year schedule, and each improvement starts its own depreciation schedule based on when it was placed in service.
Example: You spend $15,000 on a new roof in Year 3. That $15,000 is added to your depreciable basis and depreciated over 27.5 years starting in Year 3, adding roughly $545 per year to your total depreciation deduction.
Your accountant will track each improvement separately on Form 4562.
What if I bought mid-year?
In your first year of service, you can only claim a partial year of depreciation based on the month the property was placed in service (available for rent). The IRS uses a mid-month convention: if you place the property in service in June, you claim 6.5 months of depreciation (half of June, plus July through December).
Calculation: $8,727.27 × (6.5 ÷ 12) = $4,727.77 in Year 1.
The calculator shows the full annual amount; adjust for partial years with your accountant or tax software.
Can I skip depreciation?
You should not skip depreciation. Even if you don't claim it, the IRS requires depreciation recapture on depreciation "allowed or allowable" when you sell. This means you lose the annual tax benefit and still owe recapture tax.
If you haven't been claiming depreciation, work with your accountant to catch up using amended returns or a Form 3115 change in accounting method.
What if my land value is much higher or lower than 15-25%?
Location matters. Urban properties with small lots may have 40%+ land value. Rural acreage with old structures may have 5-10% building value. Use your county assessment or a professional appraisal to determine the correct allocation for your property.
The IRS expects a reasonable allocation based on market conditions. Artificially inflating the building value to maximize depreciation can trigger issues in an audit.
Other rental property deductions to track
Depreciation is just one of many deductions available to landlords. Here are others you should be tracking throughout the year:
- Mortgage interest — The interest portion of your loan payment
- Property taxes — Real estate taxes paid to your municipality
- Insurance — Landlord insurance premiums
- Repairs and maintenance — Routine fixes that restore the property to working condition
- Utilities — Water, sewer, trash, electric (if you pay them)
- Property management fees — If you use a manager
- Advertising — Listing fees, signage, photography
- Legal and professional fees — Accountant, attorney, bookkeeper
- Auto and travel — Mileage to the property for inspections, repairs, or meetings
- Supplies — Cleaning supplies, light bulbs, small tools
- Software — Property management software subscriptions (like ManorKeeper)
