The tax landscape for real estate investors shifted in ways that matter for decisions made today. Recent legislative and administrative developments mean that many property owners, especially those in the self-storage sector, can accelerate deductions and conserve cash. In particular, the reinstatement of 100% bonus depreciation for qualifying assets purchased after Jan. 19, 2026, combined with transition relief from the IRS, creates timely opportunities for owners to revisit depreciation, interest limitations and filing positions.
Before making moves, owners should understand two distinct but related ideas. First, 100% bonus depreciation allows eligible tangible property to be expensed immediately rather than capitalized and depreciated over years. Second, the IRS issued formal transition guidance on March 18, 2026—Rev. Proc. 2026-17—that affects taxpayers who previously elected to be treated as a real property trade or business (RPTOB) under Section 163(j)(7). Both concepts influence how investors handle depreciation, interest deductions and amended returns.

Why these changes matter to real estate investors
The passage commonly referred to as the One Big Beautiful Bill (OBBB) revised the interest limitation rules by excluding depreciation and amortization for tax periods beginning after Dec. 31, 2026, and reinstated permanent 100% bonus depreciation for qualifying property. That combination can increase deductible interest and permit immediate expensing of many upgrades and components. When paired with a carefully executed cost segregation study, those rules can dramatically increase first-year deductions by reclassifying building components into shorter-lived asset classes that qualify for bonus treatment.
Practical tax moves for property owners
Use cost segregation and catch-up depreciation
A quality cost segregation analysis separates a building into its component parts—electrical, lighting, site work, specialized infrastructure—so some assets can be depreciated over 5, 7, or 15 years instead of 39. Importantly, if you never performed a study after purchase, you can often perform a retrospective study and take a catch-up depreciation without amending prior returns, applying the missed depreciation to current-year income. For many self-storage operators, this approach uncovers accelerated deductions and improves near-term cash flow.
Coordinate Section 179 with bonus depreciation
The Section 179 election allows immediate expensing of qualifying equipment and systems—security controls, office furnishings, electrical upgrades—subject to taxable income limits. The practical order matters: apply Section 179 first, then elect 100% bonus depreciation for remaining eligible property. Remember that Section 179 cannot exceed taxable income, while bonus depreciation can create a net operating loss in many cases. Planning the mix of Section 179 and bonus application can maximize deductions for the year of purchase.
Rev. Proc. 2026-17 and RPTOB withdrawal: what to know
On March 18, 2026 the IRS released Rev. Proc. 2026-17, which permits taxpayers who elected RPTOB under Section 163(j)(7) for tax years beginning in 2026, 2026, or 2026 to withdraw that election. An RPTOB election historically removed the business interest limitation but required longer depreciation under the Alternative Depreciation System (ADS) and disallowed bonus depreciation. The revenue procedure lets taxpayers treat the prior election as if it were never made, enabling them to capture the OBBB benefits, including restored interest deductions and 100% bonus depreciation, by filing an amended return or administrative adjustment request (AAR) by the earlier of Oct. 15, 2026, or the applicable statute of limitations.
Filing, collateral adjustments and related rules
Withdrawing the RPTOB election requires attaching a statement to the amended return or AAR and making any necessary collateral adjustments—for example, recalculating depreciation and adjusting the depreciable basis for assets previously subject to ADS. Taxpayers generally must amend succeeding years affected by the withdrawal. The guidance also allows certain late elections out of bonus depreciation under Section 168(k)(7) and offers relief for some CFC group elections without regard to a 60-month limitation for initial specified periods beginning after Dec. 31, 2026. These changes create planning complexity but also tangible tax savings.
A checklist to avoid common mistakes and act now
To capture benefits, start with tidy records: reconcile books, separate operating expenses from capital improvements, and label purchase dates and costs. Avoid common errors like continuing to depreciate replaced assets (often write-offs are available) or lumping multiple expansion phases together. Track energy-efficiency upgrades, capture everyday deductible costs, and make tax decisions throughout the year rather than waiting until season filings. Work with a CPA experienced in real estate and self-storage tax matters to navigate amended returns, cost segregation studies, and the withdrawal process under Rev. Proc. 2026-17.
Experts such as Heidi Henderson of Engineered Tax Services highlight that accurate documentation and early planning transform tax compliance into a growth strategy. By combining clean records, a targeted cost segregation study, smart use of Section 179 and 100% bonus depreciation, and careful consideration of RPTOB withdrawal options, investors can preserve cash flow, accelerate returns, and position properties for future investment.
