The short-term rental boom has created a new wave of investors specifically buying properties to unlock accelerated depreciation through cost segregation studies, but many are generating tax losses in the wrong income bucket, rendering hundreds of thousands in deductions unusable.

The issue centers on a fundamental tax distinction that determines whether accelerated depreciation offsets your income or sits unused on your return: active versus passive income classification.

“There’s a lot of hype around cost segregation for short-term rentals,” says Brian Kiczula, founder of CostSegRx, a Sarasota-based firm specializing in cost segregation for small and midsize residential and commercial investors. “Investors are going out and specifically buying short-term rentals to do cost segregation studies. I think it’s an excellent strategy, but you have to make sure you can actually use the depreciation the way you’re expecting.”

The Active vs. Passive Income Trap

Cost segregation allows real estate investors to accelerate depreciation by reclassifying assets like decorative lighting, removable flooring, and site improvements from 27.5 or 39-year schedules to 5 or 15-year schedules. With the One Big Beautiful Bill Act making 100% bonus depreciation permanent, investors can take up to 100% of these reclassified assets as first-year deductions.

The accelerated depreciation generates losses, but whether those losses offset your W-2 income, business income, or only other passive real estate income depends entirely on your specific tax situation and material participation in the rental activity.

Short-term rentals can qualify as non-passive (active) income if certain material participation tests are met, potentially allowing losses to offset ordinary income. Traditional long-term rentals typically generate passive losses that only offset passive income unless you qualify as a real estate professional.

“I don’t know what your specific scenario is,” Kiczula explains. “I don’t know what you’re trying to accomplish with the depreciation. That’s why I always say: get a free estimate of benefit on the cost segregation study, then take it back to your CPA or tax professional and decide if it makes sense.”

The Depreciation Recapture Reality Check

Another factor investors frequently overlook: depreciation recapture on disposition.

When you sell investment property at a gain, you must recapture depreciation taken during ownership. If you accelerated $300,000 in depreciation through cost segregation in year one, then sell the property in year two, you’re paying back those deductions.

“Depreciation recapture is real,” Kiczula notes. “Before you dispose of an asset, whether you did a cost segregation study or not, have a conversation with your CPA, your financial advisors, your trusted partners. Tell them you’re planning on selling so you can figure out a disposition strategy.”

Strategic options include 1031 exchanges into replacement properties, acquiring new properties with their own cost segregation opportunities, or timing sales to optimize tax impact across multiple years.

The Design-Phase Advantage

For investors building or substantially renovating short-term rentals, incorporating cost segregation strategy during the design phase, not after construction, can dramatically increase classifiable assets.

Strategic choices include:

• Lighting design: One primary light source per room, with secondary decorative fixtures qualifying as short-life assets
• Flooring selection: LVP, floating floors, and carpet qualify as 5-year property; permanently-attached tile doesn’t
• Amenities: Swimming pools, tennis courts, and pickleball courts outside the building footprint qualify as 15-year assets

“Look at properties in Las Vegas,” Kiczula suggests. “These properties are built with cost segregation in mind because they know they need these short-life asset classifications to make the investment work after spending hundreds of millions.”

Getting It Right

The rise of short-term rental investing has created legitimate cost segregation opportunities, particularly with permanent bonus depreciation removing artificial timing pressure. But the strategy only works if:

1. Your tax situation allows you to use the accelerated depreciation
2. You understand the recapture implications on disposition
3. You’re working with a provider who evaluates your specific property condition, not just theoretical classifications

“Every property is unique,” Kiczula emphasizes. “You need someone who looks at each individual asset and understands the condition when you acquired it.”

For short-term rental investors, the conversation with your CPA should happen before the cost segregation study, not after discovering you’ve generated losses you can’t actually use.
