Unlocking Tax Savings: Bonus Depreciation Benefits for Multifamily Investors

In 2025 and into 2026, multifamily real estate investors are presented with one of the most powerful tax incentives in recent history, the permanent reinstatement of 100% bonus depreciation. This change fundamentally alters the tax landscape for investors, offering accelerated depreciation deductions, boosted cash flow, and enhanced deal economics.

What Is Bonus Depreciation?

Bonus depreciation is a provision under Internal Revenue Code Section 168(k) that allows investors to immediately deduct a large portion (or all) of the cost of qualifying property in the year it is placed into service, rather than depreciating these costs over the usual multi-year period. Traditionally, real property (like buildings) must be depreciated over decades (27.5 years for residential), but bonus depreciation makes it possible to front-load deductions associated with shorter-lived components of a property -- such as appliances, fixtures, HVAC systems, and site improvements.

Recent Change: 100% Bonus Depreciation Is Permanent

The tax law commonly referred to as the One Big Beautiful Bill Act (OBBBA) was signed into law on July 4, 2025, which made a dramatic and investor-friendly change: it restores and makes permanent 100% bonus depreciation for qualified property acquired and placed in service after January 19, 2025. This reverses the phase-down schedule that would have dropped the bonus depreciation percentage to 40% or lower.

Under the new regime:

• Investors can deduct the full cost of eligible assets in the year they begin service.

• This applies not only to brand-new components, but also for the first time under the revised rules to qualifying used property, as long as it meets the IRS criteria.

• These rules are now backed by IRS interim guidance confirming the continued application of the Section 168(k) framework with updated timelines.

Why This Matters to Multifamily Investors

Multifamily property owners and syndicators can benefit enormously from bonus depreciation, especially when paired with a cost segregation study, an engineering-based analysis that identifies shorter-lived asset components within a property. By reclassifying elements such as flooring, lighting, window treatments, parking lots, and certain improvements, investors can allocate a greater portion of the building’s cost basis into eligible categories for first-year bonus depreciation.

Here’s how this translates to real returns:

• Accelerated Deductions: Instead of spreading depreciation over 27.5 years, critical components can generate a current-year deduction, significantly reducing taxable income in year one.

• Enhanced Cash Flow: Lower federal tax liability increases after-tax cash flow dollars that can be used for debt service, reserves, or reinvestment.

• Stronger Equity Pricing: With more predictable tax outcomes, sponsors can often negotiate better equity terms and potentially higher valuations.

• Timing Advantage: For transactions completed after January 19, 2025, investors capture the full 100% deduction. Deals placed in service before that date may still be subject to the old phase-down rules.

Example in Practice

Imagine a multifamily acquisition where a cost segregation study identifies $5 million in qualifying shorter-lived assets. With 100% bonus depreciation, the investor can expense the full $5 million in year one. For investors in higher tax brackets, this could mean hundreds of thousands of dollars in tax savings immediately, freeing up capital for reinvestment or portfolio expansion.

Plan Strategically: Timing and Execution Matter

For multifamily syndicators, maximizing bonus depreciation isn’t just about tax savings, it’s about delivering stronger after-tax returns to investors and enhancing the overall value proposition of the deal.

To fully capitalize:

Be intentional about acquisition timing and cost segregation.

Closing early in the calendar year and initiating a cost segregation study immediately can help ensure the property is placed in service in time to generate first-year bonus depreciation, potentially creating meaningful passive losses for limited partners.

Coordinate closely with tax advisors and legal counsel.

In a syndication structure, acquisition dates, placed-in-service timing, partnership allocations, and K-1 reporting all need to align. Strategic planning ensures depreciation benefits are allocated properly among LPs and structured in a way that maximizes investor outcomes.

Conclusion

The return and permanent restoration of 100% bonus depreciation is a game-changer for multifamily investors. Bonus depreciation isn’t just a tax tool, it’s a strategic lever that can enhance cash flow projections, improve investor IRRs, and differentiate your offering in a competitive capital-raising environment.
