Many short-term rental (STR) owners have heard that their Airbnb or vacation rental could be treated differently under the tax rules — potentially allowing certain rental losses to be treated as non-passive and, depending on the taxpayer’s circumstances, offset other forms of income. But qualifying for this treatment requires more than simply owning a short-term rental property.
One of the biggest misconceptions is believing that every hour spent thinking about, researching, or managing an STR automatically counts toward the IRS requirements. In reality, the IRS focuses on specific qualifying operational activities and whether the owner meets one of the recognized material participation tests.
This article focuses on which activities generally count — and which don’t. A separate guide will dive into practical strategies for meeting the 100-hour test in more detail.
How Material Participation Works for Short-Term Rentals
Material participation refers to a taxpayer’s regular, continuous, and substantial involvement in the operations of a business activity. Under the passive activity loss rules, income and losses from activities in which a taxpayer does not materially participate are generally treated as passive, which limits an owner’s ability to deduct losses against other, non-passive income.
This distinction matters for STR owners because short-term rentals with an average guest stay of seven days or less are generally not treated as a traditional “rental activity” for passive activity purposes under the applicable Treasury regulations. Instead, they are more commonly analyzed like a trade or business activity. However, this does not automatically make the activity non-passive — the owner still must satisfy one of the IRS’s material participation tests to treat the activity (and any resulting losses) as non-passive.
It’s worth pausing on why this matters in practice. Under the general passive activity rules, losses from rental real estate are typically limited and can only offset passive income, with narrow exceptions. For an STR that qualifies as a non-rental activity under the average-stay rule and where the owner also materially participates, losses can instead be treated as non-passive — meaning they may be used to offset active income such as wages or self-employment earnings. This two-part analysis (average stay length, then material participation) is why owners sometimes qualify on paper but still fall short if they can’t demonstrate the hands-on involvement the IRS is looking for.
The IRS Material Participation Tests Most STR Owners Should Know
The IRS provides seven tests for determining material participation, and meeting any one of them is generally sufficient. While all seven exist, most STR owners commonly evaluate their situation under three of them, since the others tend to apply to less common scenarios, such as participation in prior years or activities involving personal services in specific industries.
The 500-Hour Test
A taxpayer materially participates if they are involved in the operations of the activity for more than 500 hours during the tax year. This test is often used by owners who actively self-manage their properties without significant outside help.
The 100-Hour Test
A taxpayer materially participates if they:
- Participate more than 100 hours during the tax year, and
- No other individual participates more hours than the taxpayer.
This comparison is generally made against each individual who participates in the activity — such as a specific cleaner, contractor, or property manager — not against a property management company as a whole. When multiple employees or contractors are involved, the analysis can become fact-specific, so owners should consult a qualified tax professional before relying on this test.
The Substantially All Participation Test
A taxpayer materially participates if their participation in the activity constitutes substantially all of the participation by anyone (including non-owners) for the tax year. This test is most relevant for owners who handle nearly everything themselves with little to no outside help — for example, a self-managing owner who occasionally hires a single cleaner but otherwise runs every aspect of the property personally.
Qualifying Activities That Generally Count Toward STR Material Participation
The IRS generally looks for active, hands-on involvement in operating the short-term rental — not passive ownership. In practice, this means the work you do should resemble running a small hospitality business rather than simply collecting a check. Qualifying activities generally fall into the following categories.
Guest Communication
Examples include:
- Responding to inquiries
- Answering guest questions
- Sending check-in instructions
- Handling complaints
- Managing reviews
Booking and Reservation Management
Examples include:
- Calendar management
- Accepting reservations
- Pricing adjustments
- Minimum-stay decisions
- Availability updates
Cleaning and Turnover Coordination
Examples include:
- Scheduling cleaners
- Inspecting completed cleanings
- Restocking supplies
- Coordinating turnovers
- Resolving cleaning issues
Maintenance and Vendor Coordination
Examples include:
- Hiring contractors
- Scheduling repairs
- Property inspections
- Emergency maintenance
- Approving repair work
Administrative Activities
Examples include:
- Bookkeeping
- Expense tracking
- Insurance coordination
- Vendor invoices
- Property records
- Financial reporting
Administrative work generally counts when it is directly related to operating the STR business, rather than general investment oversight.
Property Improvement and Operations
Examples include:
- Renovation oversight
- Furniture replacement
- Inventory management
- Safety inspections
- Equipment purchases
Example of Qualifying STR Activities
Consider Sarah, who owns one Airbnb property. Throughout a typical week, she:
- Responds to guest inquiries
- Updates nightly pricing
- Coordinates cleaners
- Inspects the property after turnovers
- Schedules repairs
- Purchases supplies
- Reviews contractor work
These are operational activities that generally contribute toward material participation when properly and contemporaneously documented. Sarah’s involvement reflects the type of active, ongoing engagement the IRS looks for — not passive collection of rental income.
If Sarah logs these tasks consistently and her total hours exceed 100 for the year, with no single cleaner, contractor, or manager logging more hours than she does on the property, she may have a reasonable basis for satisfying the 100-hour material participation test, provided she can substantiate her participation and all other applicable requirements are met.
Activities That Generally Do NOT Count
Just as important as knowing what counts is understanding what doesn’t. These activities are commonly miscounted by STR owners, and relying on them can leave a material participation position vulnerable if it’s ever examined.
Investor Activities
- Researching future purchases
- Reading investment books
- Watching STR webinars
- Market research
- Attending conferences
Passive Ownership
- Reviewing reports
- Waiting for appreciation
- Monitoring investments
- Receiving updates
Personal Activities
- Personal vacations
- Family trips
- Personal errands
- Non-business travel
Using a Property Manager Doesn’t Automatically Prevent Material Participation
This is one of the most common misconceptions among STR owners. Many assume that hiring a property manager automatically disqualifies them from meeting a material participation test.
That’s not necessarily true.
Depending on the specific facts, an owner may still materially participate if they remain actively involved in qualifying operational activities and satisfy one of the IRS material participation tests — most commonly the 100-hour test, because the comparison is generally made against each individual who participates in the activity rather than treating the management company as a single participant.
For example, a management company may assign guest communications, maintenance coordination, and scheduling to different employees. Depending on the facts, if no individual performing services for the activity participates more hours than the owner, the owner may still have a reasonable basis for relying on the 100-hour test. This is why understanding how a management company staffs and documents its work is just as important as tracking your own hours. A future article will cover strategies for qualifying under the 100-hour test while working with a property manager.
Why Documentation Matters
The IRS expects taxpayers to maintain records that substantiate their hours and activities. Under the regulations, participation may be established by any reasonable means, and records should generally reflect:
- Dates
- Activities performed
- Time spent
- Property involved
Useful sources of documentation include:
- Calendar entries
- Emails
- Guest messages
- Cleaning schedules
- Contractor communications
- Property management software logs
- Time-tracking logs
While the regulations don’t require a specific format for these records, vague or after-the-fact estimates (“I probably worked about 15 hours a week”) are much weaker than a detailed, contemporaneous log. The strongest records are created close to the time the work was performed and are corroborated by independent evidence, such as timestamped messages or software logs, rather than relying solely on the owner’s own recollection.
Common Mistakes STR Owners Make
Even experienced STR owners can undermine an otherwise solid material participation position through avoidable errors. Watch out for the following:
- Counting investor activities as participation
- Failing to document work as it happens
- Assuming all owner activities automatically qualify
- Ignoring the “more than any other individual” requirement under the 100-hour test
- Waiting until tax season to estimate hours
- Assuming that hiring a property manager automatically disqualifies them
Tips for Tracking Qualifying STR Activities Throughout the Year
Good record-keeping habits make it far easier to support a material participation position if it’s ever questioned. Consider the following practices:
- Record activities as they happen rather than trying to recreate them later. Contemporaneous records carry far more weight than year-end estimates.
- Track the date, property, task performed, and time spent for each activity, especially if you own more than one short-term rental.
- Keep supporting documentation such as guest messages, contractor emails, invoices, calendars, and maintenance records to back up your logged hours.
- Separate personal activities from rental business activities. Time spent on personal trips or errands should never be mixed in with time spent operating the STR.
- Review your participation regularly with your tax professional rather than waiting until filing season, so any gaps in documentation or borderline activities can be addressed while they’re still fresh.
How REPSLog Helps STR Owners Track Material Participation
Tracking hours accurately throughout the year — rather than reconstructing them at tax time — is one of the most effective ways to support a material participation position. REPSLog helps STR owners:
- Track hours by property
- Categorize qualifying activities
- Maintain contemporaneous records
- Organize documentation for tax professionals
- Reduce the need to reconstruct hours at year-end
The Bottom Line
Material participation is about more than simply reaching a certain number of hours. Owners must perform qualifying operational activities, meet one of the applicable IRS material participation tests, and maintain detailed, contemporaneous records to support their tax position. Consistent documentation throughout the year can make it easier to demonstrate participation and work with a qualified tax professional if questions arise.
