Understanding Bonus Depreciation in Self-Storage #
Bonus depreciation allows you to immediately deduct a large percentage of the cost of eligible property in the year it’s placed in service. Under the 2017 Tax Cuts and Jobs Act (TCJA), investors could take 100% bonus depreciation on qualifying 5-, 7-, and 15-year property—precisely the items a cost-segregation study tends to identify in a self-storage project.
For example, in 2024 a new $5 million facility with $1.5 million of 5–15-year property would have produced a 60% bonus deduction—$900,000—potentially eliminating tax on early-year cash flow depending on the investor’s broader situation.
Phase-Down Timeline #
TCJA included a scheduled reduction in available bonus depreciation:
- 2023: 80%
- 2024: 60%
- 2025: 40%
- 2026: 20%
- 2027: 0%
Subsequent legislation—and effective dates such as January 19, 2025—introduced important cut-offs and reinstatements for certain types of “qualified property.” The key nuance is whether assets were acquired, under a binding contract, or placed in service relative to these dates. Eligibility for 100% bonus may hinge entirely on meeting those timing tests. Properties outside the reinstatement window typically remain subject to the original phase-down schedule.
Planning Implications #
- Bonus depreciation applies only to property with a recovery period of 20 years or less—not to the 39-year building structure.
- Bonus accelerates deductions now but reduces remaining basis, meaning year-two through year-five deductions will be smaller.
- Depreciation recapture remains a risk at sale unless the gain is deferred through a 1031 exchange.
- Passive-activity loss rules limit the immediate use of paper losses for investors who do not materially participate.
Because of these dynamics, self-storage sponsors often model two scenarios—accelerate now versus spread later—to determine which path produces the highest after-tax IRR given hold period, exit strategy, debt structure, and investor profiles.
Bottom Line #
Bonus depreciation is a powerful but time-sensitive lever. It works best when paired with a high-quality cost-segregation study and a realistic exit plan. Know your placed-in-service dates, acquisition timelines, and eligibility tests—timing alone can swing six figures of first-year deductions on a single facility.
