Bonus Depreciation for AZ STR Owners | HomeSlice Stays

Tax Strategies Every Short-Term Rental Owner Should Understand

I'm Ellie Paget, founder of HomeSlice Stays. Owning a short-term rental isn't only about the guest experience, it's about whether the numbers behind it work for you. Some of the largest financial leverage in this business sits on the tax side, and most owners either don't know these strategies exist or assume they don't qualify. We don't give tax advice, that's your CPA's role, but we help owners understand what to ask about and connect them with the right specialists. Here's what's genuinely worth a conversation, with the current rules.

Bonus Depreciation Is Now Permanent

This is the big one, and it's no longer in flux. The One Big Beautiful Bill Act, signed into law in July 2025, permanently restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025. This is the first time Congress has made 100% bonus depreciation an ongoing provision rather than one phasing out, before this, the rate had dropped to 40% for 2025 and was scheduled to reach 0% by 2027.

What that means for an owner: eligible shorter-life assets in a property can potentially be deducted in full in the first year rather than over decades. One important catch, the property must meet both the acquisition-date and placed-in-service criteria, both after January 19, 2025, and the law does not apply retroactively to 2023 or 2024 purchases. The exact acquisition date can require analyzing contracts, which is exactly where a professional matters. OnPayWarren Averett

The Short-Term Rental Tax Distinction

There's a well-established rule that matters enormously for STR owners. Generally, rental income is passive, which limits how losses can be used. But a property is not treated as a rental activity under the passive activity rules if the average guest stay is seven days or less, or 30 days or less with substantial personal services. When that's combined with material participation, losses may be treated as non-passive and can offset W-2 or business income, without needing real estate professional status. Cherry BekaertTaxAct

This isn't an aggressive position. It's built into the tax code under IRC Section 469, recognized by the IRS, not a gray area. The key requirement is material participation: meeting one of the IRS tests, commonly the 500-hour test, the "substantially all the work" test, or the "100+ hours and more than anyone else" test. Documentation is critical, calendars, management software reports, and communication logs are what prove participation in an audit. Recostseg + 2

One honest nuance worth flagging directly: using a property management company can complicate the material participation question, because the owner must retain substantial decision-making authority and the manager shouldn't log more hours than the owner. This is genuinely fact-specific and one of the most important things to work through with a CPA before relying on the strategy, especially if your property is professionally managed. Recostseg

Depreciation and Cost Segregation

Standard depreciation is slow. Note that short-term rentals are generally depreciated over 39 years rather than 27.5, but that's not the disadvantage it sounds like, because a cost segregation study breaks the property into components with much shorter schedules (appliances, flooring, fixtures, landscaping, hardscape). Practitioners commonly find that roughly 30% of a property can be identified as short-life assets eligible for acceleration, though the real figure depends entirely on the specific property and a properly conducted, IRS-compliant study. Paired with 100% bonus depreciation, that identified portion can potentially be deducted in year one. WCG CPAs & AdvisorsThe Real Estate CPA

A Simplified Illustration (Not a Promise)

To make it concrete: on a $600,000 property, a cost segregation study might identify around 30%, roughly $180,000, as short-life assets, with the full amount deductible in year one under 100% bonus depreciation. Depending on the owner's bracket and situation, that can translate into substantial first-year tax savings. I'm deliberately not attaching a guaranteed dollar figure to your property, because the real number depends on the property, your participation, your bracket, and your full tax picture. The point is the magnitude is large enough to warrant a serious professional conversation. The Real Estate CPA

Why This Is Worth Doing Right

You could try to assemble this yourself, but the rules are genuinely intricate, the acquisition-date tests, the material-participation tests, the audit documentation, and a misstep means either missed deductions or increased audit exposure. Owners who capture these benefits cleanly do it with a CPA who specializes in short-term rentals and a properly conducted cost segregation study.

Where We Fit

We don't prepare taxes or give tax advice. What we do is help owners think like investors, understand which strategies may be relevant to their property and participation level, and connect them with seasoned STR-specialist professionals who execute them correctly. And because the management structure itself can affect the material-participation question, we work with owners thoughtfully on that, rather than pretending it's irrelevant.
