STR material participation: what counts, what doesn't
The regulations publish no list of qualifying activities. They work by exclusion — understand the two carve-outs and count everything else.
The regulations don't publish a list of qualifying activities. They work by exclusion — nearly anything you do to operate the business counts, minus two carve-outs. So the useful exercise isn't checking a whitelist, it's understanding the two exclusions and then counting everything else.
The two exclusions
1. Investor-type activity. Doesn't count unless you're involved in the day-to-day management or operations. Reviewing financials to see how you did, studying performance, monitoring the operation in a non-managerial way.
2. Work not customarily done by an owner, where a principal purpose was generating hours. An owner cleaning their own STR is ordinary and fine. An owner who pays a cleaner all year and then personally scrubs the place every weekend in December is telling a story an examiner will read.
Everything outside those two is generally participation.

The contested ones
Travel to and from the property. There's authority supporting it where the purpose of the trip is the activity, and plenty of practitioners count it. It's also the first line item an examiner probes — particularly long trips, and particularly if the property is somewhere you'd want to visit anyway. Log the purpose, not just the hours, and get your CPA's position on it.
Property search and acquisition analysis. Generally excluded. You're acting as an investor, and the activity arguably hasn't commenced yet.
Education — courses, books, podcasts, conferences, coaching. Generally investor activity and excluded. This is the most common way people inflate a log without realizing it's a problem.
Reviewing your own P&L. Reviewing results is investor activity. Doing the bookkeeping is management. Thin line, worth being conservative.
Three structural points that matter more than the list
Your spouse's hours count. Regardless of whether they hold an ownership interest, and regardless of filing status. Frequently under-counted.
Know which test you're targeting before you start logging. Most people assume the 500-hour test. But if you have no property manager and you're doing the work yourself, "more than 100 hours and more than any other individual" is often easier to clear and easier to defend. Different test, different evidence.
It's per activity, which usually means per property. Four STRs without a grouping election means four separate hour counts. People who believe they're at 500 hours across a portfolio are sometimes at 125 hours four times over, which clears nothing.
On documentation
The regulations say participation may be established by any reasonable means and don't require contemporaneous daily time reports. The Tax Court, repeatedly, has rejected reconstructed calendars and after-the-fact estimates anyway. The rule is lenient; the courts are not.
What survives is an entry with four things attached: the date, the property, the specific task, and something independent that corroborates it — a calendar entry, a text to a cleaner, a vendor invoice, a timestamped receipt. Round numbers in a spreadsheet built in March is the exact pattern that keeps losing.
This is general information, not tax advice. Thresholds, elections and dollar figures change, and the right treatment depends on your situation — check with a CPA before you act on any of it.
