Rental Property Depreciation: The Complete Guide (2026)

What Is Rental Property Depreciation?

Depreciation is one of the most powerful tax benefits available to rental property owners. It allows you to deduct the cost of your building over time, even though the property may actually be appreciating in market value. The IRS treats buildings as assets that wear out, and this "paper loss" reduces your taxable rental income each year. This guide is part of our complete rental property tax guide, which covers every tax topic landlords need to understand in 2026.

For residential rental property, the IRS requires you to use the straight-line depreciation method over a 27.5-year recovery period. This means you deduct an equal amount each year for 27.5 years, which can add up to thousands of dollars in annual tax savings. The deduction is reported on Schedule E, Line 18 of your federal tax return.

Understanding depreciation is essential because it directly impacts your cash flow, your tax bill at sale (through depreciation recapture), and your overall investment returns. Many landlords leave money on the table by miscalculating their depreciable basis or failing to take advantage of accelerated depreciation strategies like cost segregation.

The Straight-Line Method: How It Works

The straight-line method is the only depreciation method the IRS allows for residential rental property. It spreads the cost of the building evenly across 27.5 years. The formula is simple: take your depreciable basis (purchase price minus land value, plus certain closing costs) and divide by 27.5.

The IRS also applies the mid-month convention, which means that regardless of what day in the month you place the property in service, you are treated as if you started using it in the middle of that month. In your first year, you only get a partial year of depreciation based on how many months (and half-months) the property was in service.

For example, if you place a property in service on March 15, you would get 9.5 months of depreciation in the first year (mid-March through December). In years 2 through 27, you get the full annual amount. In year 28, you get the remaining partial amount to complete the 27.5-year schedule.

Land Value Exclusion: Separating Land from Building

One of the most critical steps in calculating depreciation is separating the land value from the building value. The IRS does not allow you to depreciate land because land does not wear out, become obsolete, or get used up. Only the building (and certain land improvements like driveways, fences, and landscaping) can be depreciated.

Typically, land represents 15% to 25% of the total purchase price, though this varies significantly by location. A condo in a high-rise building might have a land allocation of just 10%, while a rural property on acreage might be 40% or more. The best sources for determining your land-to-building ratio include:

• •Your county property tax assessment, which typically breaks out land and improvement values separately
• •A professional appraisal that allocates value between land and structure
• •The purchase contract if it specifies separate values for land and building
• •Comparable land sales in your area to establish a reasonable land value

Worked Example: Calculating Annual Depreciation

Let's walk through a complete example with real numbers. Suppose you purchase a single-family rental property for $300,000. You determine that the land is worth 20% of the purchase price based on your county tax assessment records.

• •Total purchase price: $300,000
• •Eligible closing costs added to basis (title insurance, recording fees, transfer taxes): $6,000
• •Total cost basis: $306,000
• •Land value (20%): $61,200
• •Depreciable basis (building only): $306,000 minus $61,200 = $244,800
• •Annual depreciation: $244,800 / 27.5 = $8,901.82 per year

If you are in the 24% federal tax bracket, that $8,901.82 annual depreciation deduction saves you approximately $2,136 per year in federal taxes alone. Over the full 27.5-year recovery period, you would deduct the entire $244,800 building value.

Cost Segregation: Accelerating Your Deductions

Cost segregation is an advanced tax strategy that reclassifies certain building components into shorter depreciation categories. Instead of depreciating the entire building over 27.5 years, a cost segregation study identifies components that qualify for 5-year, 7-year, or 15-year depreciation schedules.

Components that may qualify for shorter recovery periods include:

• •5-year property: appliances, carpeting, certain fixtures, and decorative elements
• •7-year property: office furniture used for property management, certain equipment
• •15-year property: land improvements such as driveways, sidewalks, fencing, and landscaping

A cost segregation study for our $300,000 property example might reclassify $40,000 to $60,000 of building components into these shorter categories. That means instead of deducting those amounts over 27.5 years, you could deduct them in 5 to 15 years, significantly increasing your deductions in the early years of ownership.

Cost segregation studies typically cost $5,000 to $15,000 depending on the property size and complexity. They are generally cost-effective for properties valued at $500,000 or more. The study must be performed by a qualified engineer or tax professional to withstand IRS scrutiny.

Bonus Depreciation in 2026

Bonus depreciation allows you to deduct a large percentage of the cost of qualifying assets in the first year they are placed in service, rather than spreading the deduction over the asset's full recovery period. Under the Tax Cuts and Jobs Act, bonus depreciation has been phasing down:

• •2022: 100% bonus depreciation
• •2023: 80% bonus depreciation
• •2024: 60% bonus depreciation
• •2025: 40% bonus depreciation
• •2026: 20% bonus depreciation

In 2026, bonus depreciation is at 20%. This applies to personal property identified in a cost segregation study (5-year, 7-year, and 15-year property), not to the 27.5-year building itself. If a cost segregation study identified $50,000 in qualifying components, you could take $10,000 in bonus depreciation in the first year plus regular depreciation on the remaining $40,000. Always check for legislative updates, as Congress may extend or modify bonus depreciation rates.

Depreciation Recapture at Sale

Depreciation recapture is the tax you owe when you sell a rental property that you have been depreciating. The IRS requires you to "recapture" the depreciation deductions you took during ownership and pay tax on that amount at a maximum rate of 25%. This is separate from and in addition to any capital gains tax you owe.

Here is how recapture works with our example property. Suppose you owned the $300,000 property for 10 years and claimed $89,018 in depreciation ($8,901.82 per year for 10 years). You then sell the property for $400,000.

• •Original cost basis: $306,000
• •Depreciation claimed: $89,018
• •Adjusted basis: $306,000 minus $89,018 = $216,982
• •Total gain: $400,000 minus $216,982 = $183,018
• •Recapture amount (taxed at up to 25%): $89,018, resulting in up to $22,254 in recapture tax
• •Remaining capital gain: $183,018 minus $89,018 = $94,000 (taxed at long-term capital gains rates of 0%, 15%, or 20%)

Important: the IRS taxes depreciation recapture on the amount you claimed OR should have claimed, whichever is greater. Even if you did not take depreciation deductions, you will still owe recapture tax as if you had. This is why it is always better to claim depreciation rather than skip it.

The Mid-Month Convention Explained

The mid-month convention is an IRS rule that determines how much depreciation you can claim in the first and last year of ownership. Under this convention, the property is treated as being placed in service in the middle of the month, regardless of the actual date.

For example, if you place a property in service on January 3 or January 28, the IRS treats both as if you started on January 15. This gives you 11.5 months of depreciation in the first year. The same rule applies when you sell: if you sell in October, you get 9.5 months of depreciation for that year.

IRS Publication 946 provides depreciation percentage tables (Table A-6 for residential rental property) that automatically incorporate the mid-month convention. Using our $244,800 depreciable basis example, if the property was placed in service in July, you would get 1.667% in the first year, or $4,080.82 (roughly 5.5 months of depreciation).

Common Depreciation Mistakes to Avoid

Many landlords make costly depreciation errors that can lead to IRS audits, overpaid taxes, or unexpected tax bills at sale. Here are the most common mistakes to watch out for:

• •Depreciating land: land cannot be depreciated. Always separate land value from building value before calculating your annual deduction.
• •Forgetting to claim depreciation: the IRS taxes recapture on the amount you should have claimed, so skipping depreciation costs you twice.
• •Using the wrong recovery period: residential rental property uses 27.5 years, while commercial property uses 39 years. Using the wrong period will trigger an IRS correction.
• •Not adding eligible closing costs to basis: title insurance, recording fees, and transfer taxes increase your depreciable basis and should not be overlooked.
• •Depreciating a property before it is placed in service: depreciation only begins when the property is ready and available for rent, not when you close on it.

Depreciating Capital Improvements

When you make capital improvements to your rental property (as opposed to repairs), those improvements must be depreciated separately. Each improvement gets its own 27.5-year depreciation schedule starting from the date the improvement is placed in service. Learn more about the difference in our repairs vs. improvements guide.

For example, if you install a new roof for $12,000 in year 5 of ownership, that roof gets its own 27.5-year schedule. You would deduct $436.36 per year ($12,000 / 27.5) for that improvement, in addition to the depreciation on the original building. This means you could have multiple depreciation schedules running simultaneously for one property.
