A Comprehensive Guide to Commercial Real Estate Depreciation

Commercial real estate depreciation is a strategic accounting method that allows investors to reduce the tax burden of an income-producing property over its lifetime. By treating a portion of the building’s value as an annual loss, investors can significantly reduce their taxable income and improve their cash flow, making depreciation one of the key reasons why people invest in real estate.

Commercial Property Depreciation: Understanding the Power of Paper Loss

In the world of commercial real estate (CRE), depreciation is often called a “phantom expense.” That’s because unlike other expenses like repairs or utilities, you don’t write a check for it and pay out of pocket.

Instead, it reflects that the IRS recognizes that buildings wear out over time. This allows you to deduct a portion of the building’s value from your income every year, acting as a powerful tax shelter.

Consequently, real estate investors consider depreciation to be just as important to cap rates as the cash income and potential increase in market value that a property generates.

The Foundations of Calculating Depreciation

How does asset type affect depreciation?

Not all real estate is treated equally by the IRS. The “useful life” assigned to your property dictates how much you can deduct annually:

• Residential income properties like multifamily units, duplexes and apartment complexes depreciate over 27.5 years.
• Commercial properties such as office buildings, retail centers, industrial warehouses and hotels have a depreciation lifetime of 39 years.

The property type matters because it affects the amount of money you can deduct from your taxes each year. Using a basic, straight-line method, you can deduct a residential building’s value divided by 27.5 each year, while commercial buildings only allow a deduction equal to their value divided by 39.

The Mixed-Use “80% Rule”

If you own a mixed-use building (e.g., retail on the ground floor, apartments above), you must determine which recovery period applies. If 80% or more of the gross rental income comes from residential units, the entire building can be depreciated over the shorter 27.5-year schedule, significantly increasing your annual tax shield.

How do I determine the building’s value?

To calculate your, you must first determine the building’s depreciable basis starting with its market value. This refers only to the value of the property itself, as the land it’s built on does not depreciate over time so it’s not included in the depreciation calculation.

The Basis Formula:

Purchase Price – Land Value = Depreciable Basis

For example, if you purchase a property for $1.25 million and the land is appraised at $250,000, your depreciable basis is $1 million.

How do I calculate commercial depreciation?

Once you calculate your depreciable basis, there are several methods of calculating depreciation. The simplest is the straight-line method, which is dividing the building’s value by its depreciation lifetime.

Depreciation Formula:

Depreciable Basis / 27.5 (residential) OR 39 (commercial) = Annual Allowable Depreciation Expense

Continuing the example above, with a depreciable basis of $1 million, you could deduct $25,641 in depreciation each year ($1,000,000 / 39 = $25,641). Annual depreciation continues until one of three things happen:

• the entire basis value is deducted (after 27.5 or 39 years)
• the building is sold
• the building is removed from service and stops generating income

Advanced Depreciation Tactics: How to Front-Load Your Deductions

The standard depreciation system used by the IRS is the Modified Accelerated Cost Recovery System (MACRS), applying for most tangible property, not just real estate. MACRS is further divided into two sub-systems:

• General Depreciation System (GDS), the default method with generally shorter recovery periods.
• Alternative Depreciation System (ADS), an additional method with longer recovery periods and more linear depreciation.

Regardless of the system that applies to your commercial property, real estate depreciation must follow a straight-line pattern over its depreciation lifetime.

However, savvy investors often rely on accelerated depreciation methods to front-load as much of their deductions in the first years and boost their cash flow. The most commonly used methods are cost segregation, qualified improvements and bonus depreciation.

1. Cost Segregation

While the commercial property itself must follow a 39-year depreciation pattern, that may not necessarily be true for all of its assets and components. Cost segregation involves identifying components of the building that can be reclassified as personal property (with a depreciation life of 5-7 years) or land improvements (15-year life).

This means that you can depreciate the value of elements such as flooring, appliances or landscaping over a much shorter period, boosting tax savings in the key first years after the acquisition.

To take advantage of cost segregation, you’ll first have to pay a team of engineers and tax advisors to carry out a cost segregation study to identify the elements that are viable for reclassification.

2. Qualified Improvement Property (QIP)

Under recent commercial property tax reforms, many internal improvements to non-residential buildings are classified as Qualified Improvement Property. These enjoy a 15-year recovery period rather than the standard 39 years, allowing for faster deductions.

Most improvements can be classed as QIP, with the notable exception of building improvements that enlarge the area of the building or modify its structural framework.

QIPs are a vital tool for landlords offering Tenant Improvements (TIs) as a part of lease negotiations to attract high-quality commercial tenants.

3. Bonus Depreciation

Following the Tax Cuts and Jobs Act (TCJA) in 2024, investors can often deduct a massive percentage of the cost of short-lived assets in the very first year of a property’s lifetime.

The One Big, Beautiful Bill further extended the potential of bonus depreciation, increasing the first-year deductible amount from 40% to 100% for qualifying property placed in service since 2025.

This means that property owners can immediately deduct the full value of some expenditures like new equipment, computer software or QIP. Depreciating these items in the first year rather than over their full lifetime can provide owners with a significant advantage in taxable income.

The Exit: Recapture and 1031 Exchanges

One thing that first-time investors miss is the fact that depreciation is essentially similar to a CRE loan from the government. When you sell the property for more than its depreciated value, the IRS takes those savings back through depreciation recapture, typically taxed at a maximum rate of 25% for real estate.

Case 1: Selling at a loss

Let’s return to the earlier example and say that you operated the property worth $1 million for 10 years. This means that you’ve now claimed $25,641 times 10, or $256,410 in depreciation. The property’s adjusted cost basis is now $1,000,000 – $256,410 = $743,590.

If you then sell the property for $900,000, you’re eligible to pay 25% tax on $156,410 ($900,000 sale price – $743,590 adjusted basis), or about $39,100 in taxes. While this may seem counter-intuitive since you sold your property at a $100,000 loss compared to the initial purchase price, it’s because the IRS tracks your building’s depreciation and how much you gained from claiming tax benefits through it.

Case 2: Selling at a profit

The situation is more complicated if you sell a property for more than the original purchase price you paid.

Depreciation recapture is taxed at the standard 25% rate, but that only applies to the amount you deducted. Any additional profit is taxed at a lower capital gains rate.

Let’s say you sell the same property in our previous example for $1.1 million after purchasing it for $1 million 10 years ago.

The $256,410 in depreciation you claimed over those 10 years will be taxed at 25%. However, the additional $100,000 in profit above the property’s initial purchase price will be taxed at the standard long-term capital gains tax of 15% or 20%, depending on income.

How can 1031 Exchanges help me avoid depreciation recapture?

To avoid the tax hit of depreciation recapture when selling a property, many seasoned investors utilize a 1031 Exchange. This allows you to sell your property and reinvest the proceeds into a “like-kind” property in a short timeframe, potentially deferring both capital gains and depreciation recapture taxes indefinitely.

To pull this off, you must adhere to a strict regulatory timeline that leaves very little room for error:

There are some caveats you need to keep in mind with 1031 exchanges:

• A “like-kind property” is broader than people think. Investors often trade different asset classes, such as a warehouse for a medical office. Like-kind simply means another income-producing property.
• If the sale money ever reaches your bank account, the 1031 exchange is immediately voided and the tax bill becomes due. To avoid this, a critical component of a 1031 exchange is a qualified intermediary, a neutral third party that holds the funds in escrow until the new property is bought.
• To defer all owed taxes, the new property must have a value that’s equal or greater than the one you sold. Active investors often joke about “swap ‘till you drop”, a strategy that involves rolling all of their equity into increasingly more valuable properties to defer tax losses indefinitely.

Frequently Asked Questions (FAQs)

Q: When does commercial property depreciation start?
A: The IRS allows property owners to begin depreciating their property when it is placed in service, not when the property is initially bought. However, this can happen when the building is ready and available for rent, even if you haven’t secured a tenant yet.

Q: What is the mid-month convention in depreciation?
A: The IRS uses the mid-month convention when calculating depreciation. It states that properties are only allowed to claim half a month of depreciation for the month when the property was acquired, regardless of the actual acquisition date. The same rule applies for the month in which the property was sold.
For example, if you buy a property on the 1st of January and sell it on the 20th of January the following year, the IRS will treat it as if it was bought on the 15th of January and sold on the 15th of January the following year for depreciation purposes.

Q: How does a building become “fully depreciated”?
A: For the tax purposes of depreciation deduction, a commercial property is fully depreciated after 39 years, or 27.5 years for residential income-producing properties.

Q: What is a ‘depreciation schedule’?
A: A depreciation schedule keeps track of the depreciation for each asset. A typical depreciation schedule includes a property description, cost, estimated life, method of depreciation, date purchased, current and accumulated depreciation, and net book value.

Q: Can I depreciate a vacant property?
A: Depreciation begins when a property is “placed in service”—meaning it is ready and available for its specifically assigned function (renting), even if you haven’t secured a tenant yet.

Q: What happens if I sell the property in less than a year?
A: Properties that are acquired and disposed of within the same calendar year are not eligible for depreciation. Similarly, properties that are placed in service and subsequently removed from service within the same calendar year cannot be depreciated.

Q: Is the land value always 20%?
A: The 20% figure for land value is only a rule of thumb. You should contact an appraiser or property tax assessor to calculate the exact land value and calculate your depreciation basis.

Q: Do I have to take depreciation?
A: The IRS calculates recapture based on the depreciation tax shield you could have taken advantage of. If you don’t claim it, you lose the benefit but still pay the tax when you sell the property, so it’s a good idea to always claim depreciation.
