Exclude Land: You can only depreciate the building structure, not the land. A common split is 80/20 if unknown.
Residential: 27.5 years straight line.
Commercial: 39 years straight line.

Depreciation deductions on investment properties frequently exceed rental income, creating paper losses that many investors expect to deduct against wages and salaries. The passive activity loss (PAL) rules under IRC Section 469, however, prevent this offset in most cases. Rental activities are per se passive—regardless of how much time the owner spends managing the property—meaning losses can only offset income from other passive activities.
The $25,000 rental loss allowance provides a partial exception: taxpayers with modified adjusted gross income (MAGI) under $100,000 can deduct up to $25,000 of rental losses against non-passive income annually. This allowance phases out completely at $150,000 MAGI. For high-income investors above that threshold, depreciation-driven rental losses are suspended and carried forward to offset future passive income or be released upon property sale.
Real estate professionals who spend more than 750 hours per year in qualifying real property trades or businesses—and more time in those activities than any other profession—can treat rental activities as non-passive, unlocking the ability to deduct unlimited rental losses against active income. This election can be transformative for investors whose rental depreciation significantly exceeds rental income.
An investor owning $3 million of rental property with a depreciable basis of $2.4 million generates approximately $87,273 in annual depreciation at the 27.5-year rate. If this exceeds net rents by $30,000, the real estate professional election converts that $30,000 into a deduction against wages—saving $10,500 to $13,500 in federal income tax at the 35 to 45% marginal rate. Documentation of hours worked is critical: calendar logs, property management communications, and appointment records must substantiate the 750-hour threshold.
Section 1031 like-kind exchanges allow investors to defer both capital gain and depreciation recapture taxes by rolling proceeds from one investment property into a replacement property of equal or greater value. The deferred recapture does not disappear—it transfers to the replacement property's basis, reducing the assigned basis below what would otherwise apply. Each successive 1031 exchange amplifies the eventual recapture exposure while continually deferring recognition.
Investors using serial 1031 exchanges as a permanent deferral strategy should model their cumulative recapture liability and consider step-up-in-basis planning as part of estate planning. At death, a stepped-up basis eliminates the deferred gain and accumulated depreciation recapture entirely—making the hold-to-death strategy especially powerful for investors with highly appreciated, heavily depreciated rental portfolios.
