When physicians first begin exploring real estate as an investment, they often hear experienced investors describe depreciation as one of the most powerful advantages the asset class offers. The concept sounds counterintuitive at first: the IRS is allowing you to deduct a loss on a property that may actually be appreciating in value. Understanding how this works, why the IRS allows it, and how it affects real estate investors in practice requires spending a little time with the underlying logic.
This piece explains depreciation clearly, describes how it interacts with your tax situation as a physician-investor, and addresses some of the practical implications, including what happens when you eventually sell a property that has been depreciated.
The Basic Concept
Depreciation is an accounting concept that recognizes the wear and tear on physical assets over time. A piece of medical equipment loses value as it ages and eventually becomes unusable. Tax law acknowledges this by allowing businesses to deduct the declining value of physical assets as an expense over the useful life of the asset.
The IRS applies this same logic to real estate. Residential rental properties are assigned a useful life of 27.5 years. Commercial properties are assigned a useful life of 39 years. The implication is that the IRS treats the structure on a rental property as declining in value over that period, losing roughly 3.6 percent of its value per year for residential properties, and allows the investor to deduct that theoretical decline as a business expense.
Note that it is the structure that depreciates, not the land. Because land does not wear out, it is not depreciable. When you acquire a rental property, your tax advisor will help you allocate the purchase price between land value and structure value. The structure portion is what you can depreciate.
A Concrete Example
Suppose you purchase a residential rental property for $400,000. An appraisal or cost segregation analysis determines that the land accounts for $80,000 of the value and the building accounts for $320,000. Your annual depreciation deduction is $320,000 divided by 27.5, which is approximately $11,636 per year.
If this property generates $24,000 in gross rents and you have $10,000 in operating expenses (property management, insurance, taxes, repairs), your net operating income is $14,000. But after the $11,636 depreciation deduction, your taxable income from this property drops to roughly $2,364, even though your actual cash flow is $14,000.
This is the power of depreciation: it reduces your taxable income without reducing your cash in hand. The depreciation deduction is what tax professionals call a non-cash deduction, meaning it creates a tax benefit without representing an actual cash outflow.
The Passive Activity Limitation
For most physicians, there is an important caveat. As discussed in a separate piece on real estate professional status, passive losses from rental real estate generally can only offset passive income, not the active income from your medical practice. If your rental property generates a paper loss (after depreciation) and you have no other passive income to absorb it, that loss carries forward to future years rather than reducing your current tax bill.
This does not make depreciation useless. The carried-forward losses remain available to offset passive income you generate in future years, and they are also freed up and applied against income when you eventually sell the property. But it does mean that the immediate tax benefit of depreciation is limited for physicians who are not real estate professionals and have no current passive income.
The exception is during the year of sale. When you sell a property, all accumulated carryforward losses are released and can offset the gain from the sale. This is one reason why the tax benefits of rental real estate are sometimes described as a deferral rather than an elimination: you are pushing the benefit forward to a future year when it becomes usable.
Depreciation Recapture
Depreciation comes with a future obligation you need to understand before you invest. When you sell a rental property, the IRS requires you to pay depreciation recapture tax on the depreciation you have taken. This tax is currently assessed at a maximum rate of 25 percent, separate from the capital gains rate that applies to your appreciation.
Returning to the example above: if you have held the property for ten years and claimed $11,636 in depreciation each year, you have accumulated $116,360 in total depreciation deductions. When you sell, even if you sell at the original purchase price, you will owe depreciation recapture tax on that $116,360. At a 25 percent rate, that is approximately $29,090 in additional taxes due at the time of sale.
This is not a reason to avoid depreciation. Taking the deductions over ten years and paying recapture in year ten is almost always financially superior to not taking the deductions at all, because of the time value of money and because you may be in a lower tax bracket at the time of sale. But it is a reason to understand the full picture before making assumptions about after-tax returns. A property that looks excellent on a pre-tax basis may look different when depreciation recapture is factored in at exit.
Cost Segregation
Standard depreciation assigns the entire structure a single useful life of 27.5 years for residential properties. But a property contains many components with shorter useful lives: carpet, appliances, certain fixtures, parking lots, landscaping, and various building systems. A cost segregation study, performed by an engineer or accounting firm, identifies these components and allows you to depreciate them over shorter periods of five, seven, or fifteen years rather than 27.5 years.
This front-loads the depreciation, generating larger deductions in the early years of ownership rather than spreading them evenly over 27.5 years. For an investor who has passive income to absorb the losses, or who qualifies as a real estate professional, the earlier deductions have more present value than later ones.
Cost segregation studies cost money, typically between a few thousand and ten thousand dollars depending on the property's complexity, and they are most cost-effective for properties with a purchase price above a few hundred thousand dollars. For physicians who own multiple properties or are building a substantial real estate portfolio, cost segregation is a strategy worth discussing with a real estate-savvy tax professional.
Bonus Depreciation
Tax law has periodically allowed accelerated depreciation on certain assets, including components identified through cost segregation. Under provisions that have varied in recent years, some investors have been able to deduct a large portion of the value of these short-lived components in the first year of ownership rather than over their standard useful lives. This accelerated depreciation has been a significant tax planning tool for active real estate investors.
The specific rules around bonus depreciation change with tax legislation and have been subject to phase-downs over time. As of the time this was written, the landscape was in transition. This is an area where staying current through a tax professional who works with real estate investors is more reliable than relying on general information.
1031 Exchanges and Depreciation
A 1031 exchange allows you to defer capital gains taxes on the sale of an investment property by rolling the proceeds into a similar replacement property within a specific timeframe and following specific rules. One of the less obvious benefits of a 1031 exchange is that it also defers depreciation recapture. When you complete a 1031 exchange, you do not pay recapture at the time of the exchange; the obligation carries over to the replacement property and is deferred until a taxable sale eventually occurs.
Some investors use a series of 1031 exchanges over their investing careers, deferring both capital gains and depreciation recapture indefinitely. Under current law, assets held at death receive a stepped-up cost basis, which can effectively eliminate deferred gain and recapture entirely. This represents significant estate planning potential for investors who hold real estate throughout their lifetime.
The Practical Implication for Physician-Investors
Depreciation is a real and meaningful tax benefit of owning real estate. For physicians whose passive losses are limited by the passive activity rules, depreciation still has value: it accumulates as carryforward losses, reduces taxable income from any passive income sources you develop, and is released at the point of sale to offset recognized gains. For physicians who are building a portfolio large enough to generate passive income from some properties that absorbs losses from others, or who eventually qualify as real estate professionals, depreciation becomes immediately deductible and provides current-year tax shelter.
The key is to understand how it works, plan for what it will mean when you sell, and consult with a tax professional who works specifically with real estate investors. Depreciation is not a loophole or an accounting trick; it is a deliberate feature of the tax code designed to encourage investment in rental housing. Used thoughtfully, it is one of the reasons real estate continues to be an attractive investment for high-income earners who understand the full picture.
