Bonus Depreciation Is Back: What 100% Write-Offs Mean for Memphis Rental Investors
The biggest shift in rental-property tax strategy this year didn't come from mortgage rates or the housing market — it came from Washington. When the One Big Beautiful Bill Act was signed on July 4, 2025, it permanently restored 100% bonus depreciation, reversing a phase-down that was on track to cut the benefit to 40% in 2025 and 20% in 2026. For investors buying cash-flowing single-family homes in Memphis, that's a real and frequently overlooked lever on after-tax return — and the Mid-South's low price points make it unusually easy to use.
What actually changed
Depreciation is the deduction that lets you write off the cost of a building over time to reflect wear and tear. For a residential rental, the IRS makes you spread the structure's value across 27.5 years — a slow, steady trickle. Bonus depreciation is different: it lets you deduct the full cost of certain shorter-lived components in the very first year instead of stretching them out.
Under the 2017 Tax Cuts and Jobs Act, bonus depreciation sat at 100% and then began stepping down — 80%, then 60%, and headed toward zero. The One Big Beautiful Bill Act stopped that slide and made 100% bonus depreciation permanent for qualifying property acquired and placed in service after January 19, 2025. In practical terms: the most powerful version of this deduction is back, and it isn't scheduled to expire.
"Depreciation is the quiet part of a rental's return. You can collect rent, build equity, and still show a paper loss that shelters income — and in 2026 that shelter is back at full strength."
Where cost segregation comes in
Here's the catch that trips up first-time buyers: bonus depreciation only applies to assets with a tax recovery period of 20 years or less. The building shell itself — that 27.5-year asset — doesn't qualify on its own. That's where a cost segregation study earns its keep. An engineer-based study breaks a property into its parts and reclassifies the pieces that wear out faster — appliances, flooring, cabinetry, light fixtures, driveways, fencing, and landscaping — into 5-, 7-, and 15-year buckets. Those shorter-life components do qualify for bonus depreciation, so you can deduct them up front.
How much gets reclassified varies, but studies commonly move somewhere between 20% and 35% of a property's cost into those faster categories. On a $110,000 Memphis rental, reclassifying even a quarter of the basis is roughly $27,000 that could be deducted in year one rather than dripped out over decades. That's the difference between a token first-year write-off and a five-figure one.
Why this lands differently in Memphis
Memphis's calling card has always been affordable, cash-flowing single-family rentals — and those are exactly the properties where this strategy shines. A cost segregation study costs money, but on a small portfolio of Mid-South homes the math tends to work, because the deductions are large relative to the modest purchase prices. It also stacks naturally with a renovation strategy: the money you put into a rehab creates new depreciable components, which is one more reason the value-add playbook keeps working here. Pair that with the reality that Memphis rents have held up even as insurance and taxes have climbed, and the after-tax picture on a well-bought Memphis rental can look considerably better than the pre-tax spreadsheet suggests.
The fine print — and why your CPA runs this play
Bonus depreciation is powerful, but it comes with rules that decide whether you can actually use those paper losses. Whether a depreciation loss offsets your W-2 or other income depends on the passive-activity rules and, for some investors, on real estate professional status or the material-participation tests that apply to short-term rentals. Depreciation you claim is also "recaptured" — taxed back — when you sell, though a 1031 exchange can defer that. None of this is free money; it's a timing and strategy tool, and it is genuinely CPA territory.
