1. What Is Rental Property Depreciation?

Depreciation is a cost-recovery mechanism that allows a taxpayer to deduct the purchase price of a depreciable asset over its IRS-prescribed useful life, rather than in the year of acquisition. Under the Internal Revenue Code, allowances for exhaustion, wear and tear, and obsolescence of property — defined as depreciation — begin when the property is placed in service and can be claimed until the costs have been fully recovered or the property is no longer used in the rental activity.

For rental real estate, depreciation is often the single largest deduction on the return, capable of converting positive cash flow into a paper tax loss. To be depreciable, property must be owned by the taxpayer, used in a business or income-producing activity, have a determinable useful life, and be expected to last more than one year.

Critically, you can depreciate most types of tangible property except land, such as buildings, machinery, vehicles, furniture, and equipment, as well as certain intangible property such as patents, copyrights, and computer software. The land exclusion is not a minor footnote — it is a foundational rule that drives one of the most consequential calculations tax professionals make when setting up a rental property’s depreciation schedule.

2. The Land Exclusion: Why You Cannot Depreciate Land

The IRS is unequivocal on this point. You cannot depreciate the cost of land because land generally does not wear out, become obsolete, or get used up. If there is a loss, it is accounted for upon disposition. The rationale is intuitive: depreciation compensates for an asset’s decline in utility over time. Land, in theory, endures indefinitely.

The scope of this exclusion is broader than many practitioners initially assume. The costs of clearing, grading, planting, and landscaping are usually all part of the cost of land and cannot be depreciated. However, certain land preparation costs may be depreciable if they are so closely associated with other depreciable property that a life for them can be determined along with the life of the associated property.

The consequence of ignoring this rule is not merely a disallowed deduction in the current year. Over a 27.5-year residential recovery period, a misallocation that inflates the depreciable basis by, say, $50,000 produces approximately $1,818 in excess deductions annually — a cumulative error of potentially tens of thousands of dollars that the IRS can recoup when it arrives at audit with the county assessor’s records in hand. (And it does arrive with them: IRS auditors have been known to arrive at audit with the county tax assessor’s land and building values assigned to the property tax bill, a practice reinforced by the accessibility of online assessor databases.)

3. How to Find and Substantiate the Land Value

If you buy buildings and your cost includes the cost of the land on which they stand, you must divide the cost between the land and the buildings to figure the basis for depreciation of the buildings. The part of the cost that you allocate to each asset is the ratio of the fair market value of that asset to the fair market value of the whole property at the time you buy it. If you are not certain of the FMVs of the land and the buildings, you can divide the cost between them based on their assessed values for real estate tax purposes.

The IRS itself provides a worked example in Publication 527 illustrating the ratio method using assessed values. The IRS provides that taxpayers can use any reasonable method to determine the value of land and buildings for depreciation purposes. Assessed values are commonly used, but the IRS cannot require that they be used if the taxpayer has something better.

Method 1: County Tax Assessor Records (Most Common)

The easiest method to allocate the purchase price between the land and the building is to find the property tax card for the building, available by visiting the local property assessor’s website or office. The tax card provides a value for the land and a value for the building. Apply those percentages to the actual purchase price.

The assessor’s opinion of value can be found at no cost on most city or county websites that list property tax and ownership data. As a practitioner, search for “[county name] property assessor” or “[county name] parcel viewer” to find the relevant portal. Once located, the record will show both the total assessed value and the allocation between land and improvements — the key figures needed for the depreciation schedule.

Method 2: Independent Appraisal

A full-scope land appraisal conducted by a qualified professional following Uniform Standards of Professional Appraisal Practice (USPAP) guidelines offers the most accurate land valuation and is the least likely to be disputed by the IRS. This comprehensive analysis includes sales comparisons, highest and best use, market conditions, and income generation potential.

An appraisal is particularly advisable when the county assessor’s allocation appears inconsistent with market reality — which is common in high-demand urban markets where land values represent a disproportionately large share of total property value. County tax assessors are not greatly concerned with arriving at an accurate breakdown of land vs. improvements because it has no effect on the property tax bill, which is based on total assessed value. Often, assessors apply a standard percentage to all property in an area or use out-of-date sales data.

Method 3: Purchase Contract or Closing Statement

It is also feasible for the tax preparer to use the actual purchase price as documented in the closing statement if the closing documentation segregates the portion of the price paid toward land, land improvements, buildings, and equipment. This is the most direct method when available.

Method to Avoid: Arbitrary Percentage (“Rule of Thumb”)

4. MACRS Recovery Periods and Methods

The Modified Accelerated Cost Recovery System (MACRS) is the depreciation framework that governs virtually all rental property placed in service after 1986. Under MACRS, the recovery period and method depend on the classification of property.

Residential rental property is a building in which 80% or more of the gross rental income is from dwelling units. The mid-month convention for real property means the property is treated as placed in service — or disposed of — on the midpoint of the month in which service actually begins. This affects the first year’s deduction and practitioners should use the MACRS percentage tables in IRS Publication 946, Table A-6 (mid-month convention, 27.5-year straight-line) to calculate the correct allowance.

5. Establishing Depreciable Basis

A client’s depreciable basis begins with the property’s cost basis — the purchase price plus acquisition costs (closing costs, legal fees, title insurance, transfer taxes). Certain items must be excluded (personal property allocated separately, loan costs amortized under §163, prepaid items), while capital improvements made after acquisition are added as separate depreciable assets placed in service in the year the improvement is completed.

Property Converted from Personal Use

When a client converts a primary residence to rental use, the depreciable basis is the lesser of the property’s adjusted cost basis or its fair market value at the date of conversion, minus the land value. This is a critical distinction that can significantly affect depreciation deductions, particularly in markets where property values have appreciated substantially since purchase.

Improvements vs. Repairs

Repairs that maintain property in its current operating condition are immediately deductible on Schedule E. Capital improvements that add value, extend the property’s useful life, or adapt it to a new use must be capitalized and depreciated as separate assets. Common improvement categories — roofing, HVAC replacement, structural work — begin their own MACRS depreciation schedules starting in the year placed in service. Misclassifying improvements as repairs is an audit trigger.

6. Schedule E and Form 4562: Where Depreciation Lives on the Return

This is the section most directly relevant to day-to-day return preparation. Understanding where depreciation flows — and which lines are scrutinized — is essential for clean, defensible filings.

Schedule E (Form 1040), Part I

You can generally use Schedule E (Form 1040), Supplemental Income and Loss to report income and expenses related to real estate rentals. If you provide substantial services primarily for the tenant’s convenience, report income and expenses on Schedule C instead.

In Part I of Schedule E, each rental property is reported in a separate column (columns A, B, and C). The form accommodates up to three properties per page; additional pages are attached for portfolios exceeding three properties.

Form 4562, Depreciation and Amortization

You recover some or all of your original acquisition cost and the cost of improvements by using Form 4562, Depreciation and Amortization, beginning in the year your rental property is first placed in service, and beginning in any year you make improvements or add furnishings.

Form 4562 is required in the first year depreciation is claimed and in any subsequent year that new depreciable assets are added. The form is not required in years where no new assets are placed in service and no §179 or bonus depreciation elections are made — in those years, the depreciation amount flows directly from prior-year depreciation schedules into line 18 of Schedule E. However, many practitioners attach Form 4562 annually for documentation clarity.

Passive Activity Loss Limitations

Rental activities are generally treated as passive activities under §469. If Schedule E shows a net rental loss, the deductibility depends on the taxpayer’s active participation status and modified AGI. Taxpayers who actively participate and have MAGI below $100,000 may deduct up to $25,000 of rental losses annually; this allowance phases out between $100,000 and $150,000 MAGI. Real estate professionals who meet the material participation requirements under §469(c)(7) are not subject to the passive activity limitation.

7. Cost Segregation and Bonus Depreciation in 2026

Cost segregation is an engineering-based tax strategy that disaggregates the components of a rental building into shorter-lived asset classes — 5-year, 7-year, and 15-year property — rather than depreciating the entire structure over 27.5 or 39 years. When combined with bonus depreciation or §179, cost segregation can front-load substantial deductions into the early years of ownership.

If a rental property includes depreciable assets such as furniture and appliances (furnished rentals, corporate housing), outdoor improvements (fences, walkways, lighting), or specialty systems (security systems, irrigation systems), these assets may qualify for shorter depreciation periods of 5 to 15 years instead of 27.5 years.

Bonus Depreciation in 2026

The 100% special depreciation allowance is restored for qualified property acquired and placed into service after January 19, 2025, under the One Big Beautiful Bill Act signed July 4, 2025. However, the building structure itself (residential or nonresidential real property) is explicitly excluded from bonus depreciation — only personal property and qualified improvement property (QIP) components identified through cost segregation are eligible.

8. Depreciation Recapture at Sale (§1250)

Every dollar of depreciation claimed on a rental property creates a corresponding recapture obligation at the time of sale. Tax professionals must counsel clients on this liability proactively — the tax impact at disposition often surprises owners who focused only on the annual deduction benefit.

Under §1250, gain attributable to prior depreciation on real property is taxed as “unrecaptured §1250 gain” at a maximum federal rate of 25% — higher than the standard 15% or 20% long-term capital gains rate that applies to appreciation above the original purchase price. The unrecaptured gain equals the lesser of the total gain or the total depreciation previously allowed (or allowable, whether or not actually claimed).

9. Audit Risk and Documentation Best Practices

Rental property depreciation is a consistent IRS examination focus. The areas of highest examination risk and the corresponding documentation standards are:

1. Land allocation: Retain a copy of the county assessor’s land/improvement breakdown from the tax year of acquisition. If using an appraisal, retain the full appraisal report. This documentation should be preserved for the life of the property plus at least three years after disposition.
2. Placed-in-service date: Document the date the property was first ready and available for rent — not the date of first occupancy. Retain advertisements, lease agreements, or utility activation records. The placed-in-service date determines the first month of the mid-month convention calculation on Form 4562.
3. Improvements vs. repairs: Maintain a capital improvement log with invoices, contracts, and completion dates for each improvement. Each improvement is a separate depreciable asset with its own placed-in-service date and recovery period.
4. Cost segregation studies: Retain the engineer’s study report. The IRS may request the underlying analysis if the accelerated classifications are challenged.
5. Basis schedule: Maintain a running depreciation schedule (original basis, annual deductions, adjusted basis) for every property in the client’s portfolio. This schedule is essential for computing gain/loss at disposition and for recapture calculations.
