Property Depreciation Tax Benefits: A Guide for Real Estate Investors

Depreciation is one of the most valuable tax benefits available to real estate investors. It allows you to deduct the cost of your investment property over time, reducing your taxable income even while the property may be appreciating in value.

What Is Property Depreciation?

The IRS considers rental property a business asset that wears out over time. Depreciation lets you deduct a portion of the property's cost each year as a business expense. This is a paper deduction — you do not actually spend any money, yet it reduces your taxable rental income.

The key distinction: you depreciate the building, not the land. Land does not wear out and cannot be depreciated.

How Depreciation Is Calculated

Residential rental properties are depreciated over 27.5 years using the straight-line method. Commercial properties use a 39-year schedule.

Annual Depreciation = (Property Cost - Land Value) / 27.5

For example, if you purchase a rental property for $300,000 and the land is valued at $60,000, your depreciable basis is $240,000. Your annual depreciation deduction would be approximately $8,727.

Use our Depreciation Calculator to determine your annual depreciation deduction based on your specific property details.

Determining Your Depreciable Basis

Your depreciable basis includes more than just the purchase price:

• Purchase price — the amount you paid for the property minus the land value
• Closing costs — certain settlement charges add to your basis, including title fees, legal fees, and recording fees
• Improvements — capital improvements made after purchase increase your basis
• Minus land value — typically determined by the tax assessor's allocation or an appraisal

How Depreciation Reduces Your Taxes

Consider this scenario:

• Annual rental income: $24,000
• Operating expenses: $10,000
• Mortgage interest: $8,000
• Depreciation: $8,727

Without depreciation, your taxable income would be $6,000. With depreciation, you have a paper loss of $2,727 — meaning zero tax on your rental income, and potentially a deduction against other income.

Cost Segregation Studies

A cost segregation study breaks down your property into component categories that can be depreciated over shorter timeframes:

• 5-year property — appliances, carpeting, and certain fixtures
• 7-year property — office furniture and certain equipment
• 15-year property — landscaping, parking lots, and fences
• 27.5-year property — the building structure itself

By accelerating depreciation on shorter-lived components, you can front-load your deductions and reduce taxes significantly in the early years of ownership. Cost segregation studies typically make sense for properties valued at $500,000 or more.

Depreciation Recapture

When you sell a depreciated property, the IRS recaptures the depreciation benefit. You will owe taxes on the depreciation you claimed, currently at a maximum rate of 25%. This is important to factor into your exit strategy.

However, you can defer depreciation recapture through a 1031 exchange, which allows you to roll the proceeds into a new investment property and continue deferring taxes.

Bonus Depreciation

Under current tax law, certain components identified through a cost segregation study may qualify for bonus depreciation, allowing you to deduct a large percentage of their cost in the first year. The specifics change with tax legislation, so consult a tax professional for current rules.

Common Depreciation Mistakes

Avoid these errors:

• Depreciating land — only the building and improvements are depreciable
• Starting too late — begin depreciating when the property is placed in service
• Incorrect basis — failing to include closing costs and improvements
• Not claiming depreciation — the IRS treats depreciation as taken whether you claim it or not
