Treas. Reg. §1.469-5T(a) lists seven ways to materially participate. Short-term rental owners realistically use three of them: more than 500 hours, more than 100 hours combined with participating at least as much as any other individual, or substantially all of the participation in the activity. Which one you can meet depends less on how hard you work than on who else touches the property. Pick the target in January, because the answer changes what you have to record all year.
The three that matter
The 500-hour test. More than 500 hours of participation in the activity during the year. No comparison to anyone else — a full-service manager can be doing three times your hours and you still pass if you personally clear 500. The catch is the number: roughly ten hours a week, every week, on one property.
The 100-hour test. More than 100 hours, and your participation is not less than that of any other individual, including people you pay. Far easier on the number, far harder on the evidence, because you now have to know what your cleaner, co-host, handyman and manager's staff each did.
The substantially-all test. Your participation constitutes substantially all of the participation by all individuals in the activity. No hour threshold at all. This is the test for the owner who does everything personally — and it fails the moment a cleaner is hired, unless their time is genuinely trivial.
The other four tests exist and occasionally apply, including the facts-and-circumstances test and the tests built on significant participation activities. They come with their own conditions and are worth a conversation with your CPA rather than a plan of your own.
Choose by staffing model, not by ambition
| How the property is run | Realistic target | What the log must carry |
|---|---|---|
| You do everything, no paid help | Substantially all, or 100 hours | Your hours, plus a note that no one else participated |
| You do the work, a cleaner does turnovers | 100 hours + comparison | Your hours and the cleaner's estimated hours |
| Co-host or part-time manager | 100 hours + comparison, carefully | Every individual's hours, month by month |
| Full-service property manager | 500 hours, or reconsider | Your hours only — but 500 of them |
The middle two rows are where most short-term rental owners sit, and they are the rows where the second half of the 100-hour test decides the year. A cleaning company doing 60 three-hour turnovers is 180 hours by one individual if the same person does them all. Your 130 hours lose. The 100-hour test guide works through the comparison; the practical consequence is that you cannot know whether you passed unless you tracked someone else's time as well as your own.
Why 500 is harder than it sounds, and 100 is easier than it looks
Owners consistently overestimate 500 and underestimate 100.
Five hundred hours on one property means the equivalent of twelve full working weeks. Unless you are doing every turnover yourself in a high-occupancy market, or you spent the year on a renovation you personally ran, you are unlikely to get there honestly. Logs that reach 500 through generous rounding are the logs that draw the most scrutiny.
One hundred hours is about two hours a week. An owner who does the pricing, handles the messages, meets the vendors, does a few turnovers and fixes things on visits usually passes the number without trying. What that owner typically lacks is proof — and an estimate of the cleaner's time.
So for most people the question is not "can I reach the threshold." It is "can I show it, and can I show I did more than anyone else."
Pick the test in January
This matters because the three tests need different records.
If you are aiming at 500, the record is about volume and credibility: many specific entries, real durations, and corroboration for the big blocks. Nobody has to know what your cleaner did, but every one of your own hours has to survive.
If you are aiming at 100 plus the comparison, the record is about coverage: your hours, plus a running estimate for every other individual, updated as invoices arrive. Missing the other-participants column is the single most common way this test fails in an examination, because the owner cannot rebut the examiner's estimate with anything.
If you are aiming at substantially all, the record is about absence: your hours, plus evidence that essentially nobody else worked on the property.
STR Tracker lets you set the goal per property so the progress you see all year is measured against the test you actually intend to meet, rather than a generic total. A spreadsheet does the same job with a header row that says what you are aiming for and a column for everyone else.
Log so any of the three can be evidenced
You do not have to commit irrevocably in January. A log that records, for every entry, the date, the property, a specific task description, real minutes and who performed it, can be totalled against any of the three tests at year end. That is the whole design goal. The log template has the columns; the free spreadsheet version is the same structure if you would rather start there.
What you cannot do at year end is invent the other-participants column. Nobody remembers in March how many turnovers the cleaner did in June, and invoices without hours on them are only half an answer. Ask vendors to put time on their invoices starting now.
A mid-year check worth doing
Twice a year, run three numbers for each property: your hours to date, the largest single other individual's hours to date, and the days and stays so far. Ten minutes. If your hours are tracking under 100, you know in July rather than January, and there is still a season left to change how the property is run — or to decide with your CPA that this is not the year for it.
