If you own a vacation rental on 30A—or you’re weighing a purchase in Rosemary Beach, Seaside, Grayton Beach, or anywhere along the South Walton corridor—the tax treatment of that property can matter nearly as much as the rental income it produces. Short-term rental bonus depreciation is the strategy investors ask about most right now, and for good reason: 2025 federal tax legislation permanently restored 100% bonus depreciation, and short-term rentals occupy an unusual, potentially favorable corner of the tax code. One important note before we go further: this article is general education, not tax, legal, or accounting advice. Stroop Group / Mark Stroop LLC is a real estate team, not a tax advisor, and every rule described here carries qualifications that depend on your personal situation. Review any strategy with a licensed CPA or tax advisor before acting on it. With that understood, knowing the framework will help you ask sharper questions. Let’s dive in.
Why Depreciation Matters for 30A Rental Owners
Depreciation is the tax code’s recognition that buildings and their components wear out over time. When you buy a residential rental property, the IRS generally lets you deduct the cost of the building—not the land—over 27.5 years. On a 30A vacation rental purchased at a meaningful price point, that annual deduction is substantial, but it arrives slowly, spread across nearly three decades. The deduction is also a “paper” expense: it reduces taxable income without reducing cash flow. A property can produce positive cash flow while showing a tax loss, and that gap is the foundation of nearly every rental tax strategy. The question that separates a modest benefit from a significant one is timing—how much of that deduction you can legitimately move into year one. That is exactly what cost segregation and bonus depreciation are designed to do.
100% Bonus Depreciation Is Back—Permanently
Under the 2017 Tax Cuts and Jobs Act, bonus depreciation had been phasing out: 80% in 2023, 60% in 2024, and scheduled to drop to 40% in 2025. The 2025 federal tax legislation commonly called the One Big Beautiful Bill Act reversed that path. According to the IRS, the law provides a permanent 100% additional first-year depreciation deduction for qualified property acquired and placed in service after January 19, 2025. National accounting firm BDO and Thomson Reuters both confirm the same framework: the phase-down is gone, and full first-year expensing of qualified property is now standing law rather than a temporary window. The key limitation for real estate investors is that bonus depreciation applies to property with a tax recovery period of 20 years or less. The house itself, at 27.5 years, does not qualify—which is precisely why cost segregation matters.
How Cost Segregation Front-Loads Your Deductions
A cost segregation study is an engineering-based analysis that separates a property purchase into its components. Instead of treating the entire building as a single 27.5-year asset, the study identifies items that the tax code assigns shorter lives: five-year property such as appliances, furniture, and carpeting; seven-year property such as certain fixtures; and 15-year land improvements such as driveways, fencing, landscaping, and pools. Those reclassified components—because their recovery periods fall at or under 20 years—are eligible for 100% bonus depreciation in the year the property is placed in service. For a furnished 30A vacation home with a pool, outdoor living areas, and high-end finishes, the reclassified share can be a meaningful slice of the purchase price, which is why these studies are common among serious short-term rental investors. A study has a real cost and its value depends on your price point, your tax bracket, and your hold period, so whether it pencils out is a question for your CPA, not a foregone conclusion.
The Short-Term Rental Treatment: Where 30A Properties Fit
Here is where short-term rentals differ from long-term rentals. Under the passive activity rules of Section 469, rental losses are generally passive—usable against passive income but not against wages or business income. However, under the Treasury regulations, a property whose average period of customer use is seven days or less is generally not treated as a “rental activity” at all for passive-activity purposes. That means an owner who materially participates in the activity may be able to treat the losses—including large first-year losses created by cost segregation and bonus depreciation—as non-passive, and use them against other income such as W-2 wages. This is what tax professionals informally call the short-term rental loophole. Many 30A rentals booked in weekly and weekend patterns produce average stays under seven days, but the average is calculated from your actual guest history, not assumed. It is a computation your CPA should run, not a box you check.
Material Participation: The Tests That Matter
The seven-day rule alone is not enough—you must also materially participate in the activity. The IRS provides seven material participation tests, and meeting any one of them is sufficient. The most commonly relevant are: participating more than 500 hours during the year; performing substantially all of the participation in the activity; or participating more than 100 hours and more than any other individual—including your cleaner, handyman, or property manager. Activities like guest communication, managing listings and pricing, coordinating turnovers, and handling repairs generally count; investor-type activities like reviewing statements generally do not. If a full-service property manager runs the operation, qualifying becomes difficult. Owners who pursue this treatment typically keep contemporaneous time logs, because material participation is a facts-and-circumstances determination the IRS can examine. Which test you can realistically meet—and document—is a conversation to have with your CPA before the tax year ends, not after.
Depreciation Recapture: The Other Side of the Ledger
Accelerated deductions are a timing benefit, not free money. When you sell, the depreciation you claimed generally comes back into the picture through recapture: gain attributable to depreciation on the building is taxed at rates up to 25%, and gain attributable to depreciation claimed on shorter-life personal property can be taxed as ordinary income. Deferral tools such as a 1031 exchange exist, but they carry their own strict requirements and timelines. None of this makes the strategy unattractive—a deduction today is generally worth more than the same deduction spread over decades—but your exit plan and hold period belong in the analysis from the start, and recapture math is squarely CPA territory.
What to Confirm With Your CPA
Before building a purchase or tax plan around this strategy, confirm the specifics:
- Whether your property’s average guest stay, computed from actual bookings, falls at seven days or less.
- Which material participation test you can realistically meet, and how you will document your hours.
- Whether a cost segregation study makes economic sense at your price point, tax bracket, and expected hold period.
- That your acquisition and placed-in-service dates fall after January 19, 2025, and how the current rules apply to your closing timeline.
- How depreciation recapture would affect your after-tax proceeds at sale, and whether deferral strategies fit your plans.
- How the strategy interacts with your overall return—and with Walton County licensing and local short-term rental requirements on the operations side.
Building a 30A Strategy Around the Numbers
Tax treatment should sharpen a good investment, not rescue a weak one. The fundamentals that drive 30A rental performance—location and beach access, rental history, community rental policies, insurance costs, and realistic revenue—still come first; the depreciation strategy is a layer on top for owners who operate their properties actively.

FAQs
What is the current bonus depreciation percentage?
According to the IRS, qualified property acquired and placed in service after January 19, 2025 is eligible for a 100% first-year deduction, made permanent by 2025 federal tax legislation. Your CPA can confirm how the effective dates apply to your purchase.
Does the entire house qualify for bonus depreciation?
No. The building itself is 27.5-year property and does not qualify. Bonus depreciation applies to components with recovery periods of 20 years or less—typically identified through a cost segregation study.
What makes a rental “short-term” for tax purposes?
Under the passive-activity regulations, a property whose average period of customer use is seven days or less is generally not treated as a rental activity. The average is calculated from your actual guest stays.
Can rental losses really offset my W-2 income?
Potentially—if the average-stay test is met and you materially participate in the activity. Both requirements have technical definitions, so treat this as something to verify with a CPA, not a guarantee.
What happens to these deductions when I sell?
Depreciation is generally recaptured at sale and taxed, partly at rates up to 25% and partly as ordinary income depending on the asset class. The strategy is a timing benefit, and exit planning matters.
