Short-Term Rentals & 2025 Tax Savings

Short-term rentals have exploded in popularity over the last few years, but what makes them especially attractive isn’t just the potential for higher nightly rates—it’s the powerful tax strategy they allow, often referred to as the short-term rental “loophole.”

If you want to offset W-2 or active business income through real estate, this episode provides the STR Loophole refresher you need.

The Passive Activity Rules & Why They Matter

Most people know that rental income (and rental losses) are usually classified as “passive.” Under the Tax Reform Act of 1986, if you’re a high-income earner, you typically cannot use passive losses from rentals to offset your non-passive income—like W-2 wages or business profits. The law was designed to prevent high earners from generating large paper losses and wiping out their regular income tax bill.

Ways to reclassify losses from passive to non-passive:

• Real Estate Professional Status (REPS) – Requires at least 750 hours and more than half of your working time in real estate activities.
• Short-Term Rental Exception – If you offer an average guest stay of seven days or less, it can be treated as a business rather than a rental, eliminating the need to meet REPS.

Short-Term Rentals (STRs) as a Business

A property with an average guest stay of seven days or less typically qualifies under this exception.

Alternatively, if the average stay is 30 days or less and you provide substantial services (daily cleaning, meals, etc.), you can also trigger the same reclassification.

Once reclassified as non-passive, you can use any paper losses (especially those amplified by cost segregation and bonus depreciation) to offset W-2 or active business income.

Why it’s powerful:
By classifying a short-term rental as a non-passive “business,” you can take advantage of accelerated depreciation—often via cost segregation—to create large paper losses on your tax return. These losses could potentially save you five or six figures in taxes in a single year.

Material Participation: The Key Requirement

Even though you no longer need 750 hours for REPS, you do have to materially participate in your short-term rental. There are seven tests for material participation, but three commonly apply:

1. 500-Hour Test – You (and your spouse, if married) put in 500+ hours on that property.
2. Substantially All Work – You and/or your spouse do essentially all tasks (little to no outside help).
3. 100-Hour “More Time Than Anyone Else” Test – Combined with your spouse, you spend at least 100 hours, and no single individual (like a cleaner, co-host, or manager) spends more time on the property than you do.

Pro Tip:
Most investors opt for the 100-hour test because it’s more achievable than 500 hours. However, it’s crucial to document your time and the time of anyone you hire. In an audit, the IRS will want to verify that you truly spent more hours than any service provider.

2025 Considerations: Bonus Depreciation Phase-Down

• Bonus Depreciation dropped from 100% in prior years to 60% in 2024, and it’s scheduled to be 40% in 2025 under current law.
• Despite the reduction, the short-term rental strategy remains very compelling—especially if you’re in a higher tax bracket. Even at 40% bonus depreciation, you can still significantly reduce your tax liability.
• Potential for Legislative Changes: Lawmakers have discussed reinstating or extending 100% bonus depreciation, so keep an eye on tax news as 2025 approaches.

Common Mistakes & Audit Red Flags

• Treating STRs Like a Passive Long-Term Rental
  Short-term rentals require active management, from price adjustments to frequent cleanings. Expect more work upfront—this is a business rather than a set-it-and-forget-it investment.
• Misunderstanding Personal Use
  If you use the property personally (for vacations, etc.), be aware of the 14-day guideline. Surpassing 14 days of personal use can restrict or negate your ability to take the larger deductions. Even a few personal days can reduce what you’re allowed to claim.
• Outsourcing Everything to a Property Manager in Year 1
  Material participation is most critical in your first year when you claim the bulk of your deductions through bonus depreciation. If a property manager does all the work, it’s difficult to prove you (or your spouse) materially participated.
• Not Keeping Time Logs
  You need to track (a) your hours and (b) others’ hours—especially if you’re using the 100-hour “more than anyone else” test. Good documentation wins audits.
• Failing to See an Audit Coming
  The IRS has increased scrutiny on short-term rental claims. Common incorrect claims agents might make:
  • “You must qualify for REPS.” (Not true if you meet short-term rental rules.)
  • “You need to file on Schedule C.” (Not true unless you’re providing hotel-like daily services.)
  • “Spouses can’t combine hours.” (They can combine hours for short-term rentals.)

How to Prepare & Get Help

Given the complexity, proactive planning is key. You want to establish a good bookkeeping system and maintain detailed time logs from the start. This way, if you are ever audited, you’ll have airtight records demonstrating material participation and eligibility for the STR exception.

Final Thoughts

Short-term rentals can be an incredibly lucrative strategy for real estate investors looking to significantly reduce their tax bills—if you do it right.

It combines the best of both worlds:

• Potential for high nightly rates in popular markets
• Ability to accelerate deductions and convert losses into immediate tax savings

The key is education and preparation. Understand local regulations, know the federal guidelines, diligently track your time, and don’t be afraid to seek professional guidance. With smart planning, the short-term rental loophole remains one of the most powerful tools in a real estate investor’s tax toolbox—heading into 2025 and beyond.

0:00 – 1:04 | Introduction & Episode Overview

Thomas Castelli, CPA (00:00)
Thanks for tuning into this week’s episode of the TaxSmart REI podcast. If you’re tuning in, this is probably the first episode you’ll be hearing in 2025, even though we’re releasing it on the last day of the year.

Today, we’re talking about short-term rentals and how to maximize your short-term rental tax savings in 2025. We’ll cover the rules, why you need the short-term rental loophole, mistakes to avoid, what we’re seeing on the audit front, changes to expect in 2025, and more. Whether you’re a seasoned short-term rental investor or just getting started, you won’t want to miss this. Let’s jump in.

1:05 – 2:46 | Why Short-Term Rentals? The Passive Activity Rules

Thomas Castelli, CPA
All right, and we’re back. Again, today we’re talking about short-term rentals—specifically, how to maximize your short-term rental tax savings in 2025.

Let’s kick it off with the main question: Why do we need the short-term rental strategy to begin with? It all goes back to the passive activity rules.

Ryan, do you want to explain what these rules are and why they’re so important for real estate tax planning?

Ryan Carriere, CPA (01:04)
Sure. A bit of history first: The passive activity rules date back to the Tax Reform Act of 1986—so nearly 40 years now. Essentially, income is split into two main categories: non-passive (like W-2, business profits, portfolio income) and passive (like most rental real estate). By default, rental real estate falls into the passive bucket, which means if you’re a high-income earner, you can’t automatically use real estate losses to offset your other income.

The ways around that are:

• Real Estate Professional Status (REPS)
• Short-Term Rental Exception

We’ll focus on the short-term rental exception today.

2:47 – 5:06 | Real Estate Professional Status (REPS) vs. Short-Term Rental Loophole

Thomas Castelli, CPA (02:46)
Exactly. If you have a high income, your rental losses are stuck in the passive bucket unless you qualify as a real estate professional. REPS generally requires 750 hours and more than half your working time in real property trades or businesses, which is difficult if you hold a full-time job or run a full-time business.

That’s where the short-term rental exception—often called the “STR loophole”—comes in. These rules were originally created for hotels and motels in the 1980s. With the rise of Airbnb and VRBO, everyday investors can apply them.

5:07 – 6:43 | Defining the Short-Term Rental “Loophole”

Thomas Castelli, CPA (05:06)
So, what is the short-term rental loophole? If your average guest stay is seven days or less, it’s not considered a “rental activity” for tax purposes—it’s treated more like an active business. Another variant is if your average stay is 30 days or less and you provide substantial services (daily cleaning, meals, etc.), but most folks rely on the seven-days-or-less rule.

Once you do that, you do not need to qualify for real estate professional status. Instead, you use the material participation tests.

6:44 – 8:48 | Material Participation: The Three Most Common Tests

Ryan Carriere, CPA (06:43)
There are seven total tests for material participation, but these three matter most for short-term rentals:

• Spend 500 hours on the activity (combined for you and your spouse).
• Do substantially all of the work yourself.
• Spend more than 100 hours on the activity and no one else spends more time than you.

The 100-hour test is the most common because 500 hours is a big commitment. The big gotcha: you must document not just your time, but also time spent by cleaners, maintenance people, co-hosts, etc. so you can prove you logged more hours than any other individual.

8:49 – 10:42 | Why It’s So Powerful: Cost Seg & Bonus Depreciation

Thomas Castelli, CPA (08:48)
This strategy is powerful because once you classify your short-term rental as non-passive, you can use cost segregation plus bonus depreciation to accelerate a lot of losses into the first year. These “paper losses” can offset your W-2 or business income, often leading to five- or six-figure tax savings.

10:43 – 11:13 | Changes in 2025: Bonus Depreciation Phases

Thomas Castelli, CPA (10:42)
What’s happening in 2025? Bonus depreciation is set to drop to 40% that year (down from 60% in 2024). Under current law, it’ll keep phasing down unless Congress acts. Even at 40%, this is still a great strategy if your goal is to offset active income.

11:14 – 14:20 | Local Regulations & Potential Federal Updates

Ryan Carriere, CPA (11:13)
Right, the IRS hasn’t eliminated or changed the short-term rental loophole itself. Where we do see changes is often at the local or state level—like New York City’s new Airbnb restrictions. At the federal level, there’s talk about bonus depreciation possibly going back to 100%, but we’ll have to see.

14:21 – 19:00 | Common Mistakes to Avoid

Thomas Castelli, CPA
Let’s highlight a few common mistakes and pitfalls:

• Not Realizing Short-Term Rentals Are a Business
  • You have frequent guest turnover, cleaning, and active marketing. It’s not a “set it and forget it” like a long-term lease.
• Misunderstanding the 14-Day Personal Use Rule
  • Staying under 14 days of personal use in the property helps maximize deductions. Even 1–14 days can reduce your deductible share slightly. Over 14 days can cause bigger issues for using these losses.
• Using a Full-Service Property Manager in Year One
  • If you outsource it all, you probably won’t meet material participation. Consider self-managing at least in that first year.
• Not Documenting Time
  • You have to track your hours plus hours of cleaners, handymen, etc. Especially if you’re doing the 100-hour “more time than anyone else” test.

19:01 – 25:00 | The Audit Landscape: Common IRS Arguments

Thomas Castelli, CPA
We’re seeing more audits now that short-term rentals have become popular. Three common IRS arguments and why they’re incorrect:

1. “You must be a Real Estate Professional.”
   • Not true if the average stay is seven days or less. You only need material participation.
2. “You have to file on Schedule C.”
   • Typically false for standard Airbnbs that don’t provide “substantial services” like a hotel.
3. “Spouses can’t combine hours.”
   • For short-term rentals, you can combine hours as spouses. The IRS sometimes confuses it with the rules for REPS, which are stricter.
     If you have proper documentation, short-term rentals are absolutely a bona fide strategy. We’ve won audits where these arguments came up.
