The Short-Term Rental Tax Strategy and the 100-Hour Test

Why short-term rentals are treated differently

A rental with an average guest stay of seven days or less is generally not treated as a “rental activity” under the passive activity rules the way a long-term rental is. That distinction is what people mean by the short-term-rental strategy: if you materially participate, losses from the activity may be treated as non-passive — without needing real estate professional status.

The catch is the phrase materially participate. That is not a vibe; it is one of a set of hour-based tests, and you have to be able to show you met one.

The 100-hour test is usually the crux

Several tests can establish material participation, but for an owner-operated short-term rental the most reachable one is often this: you participated for more than 100 hours during the year, and no other individual participated more than you did.

That second half is the part people miss. It is not enough to log your own 120 hours — if your cleaning service put in 150, you did not do more than anyone else. This is exactly why a serious log records other participants’ hours alongside your own.

What counts as participation

Hands-on operating work generally counts. Passive, investor-type activity generally does not.

• Counts: guest communication, cleaning and turnovers, maintenance and repairs, supply runs, bookkeeping for the activity.
• Weak or excluded: purely investor activities like reviewing financial statements, or work you did not actually perform.
• Always: work done by others (cleaners, co-hosts, managers) — track it so the “more than anyone else” comparison is documented.

Keep the hours the strategy depends on

The strategy is only as strong as its documentation. Start with the free material participation log template, then automate it with STR Tracker — which logs hours in seconds, captures other participants’ hours for the 100-hour comparison, and exports a CPA-ready record for any period.
