What counts as a rental period?

Each booking or stay is a separate rental period, regardless of whether the same guest books multiple times.

Can property management hours count toward material participation?

Yes, but you must be meaningfully involved. Simply hiring a property manager and being hands-off typically doesn’t qualify. You need to be actively making decisions and managing the operation.

The 7-Day Rule: What It Means for Passive Losses

Last updated: January 2026 · 8 min read · Written by Hawaiʻi STR Advisor

Overview of the 7-Day Rule

Under IRC Section 469, rental activities are generally treated as passive activities. However, there’s an important exception: if the average period of customer use is 7 days or less, the activity is not automatically treated as a rental activity. This distinction is critical for STR investors because it opens the door to deducting losses against active income — provided you materially participate in the management of the property.

Material Participation Requirements

To take full advantage of the 7-day rule exception, you must meet one of seven material participation tests defined by the IRS. The most common for STR owners: spending more than 500 hours per year on the activity, or spending more than 100 hours and more than any other individual. Activities count: communicating with guests, managing bookings, coordinating cleaning, handling maintenance, marketing the property, and overseeing property managers.

Calculating Average Rental Period

You calculate the average rental period by dividing the total rental days by the number of separate rental periods. If you had 200 rental days across 50 bookings, your average is 4 days. Important: long-term stays can bring your average above 7 days and potentially disqualify you from the exception. Track your bookings carefully and consider your mix of short vs. longer stays.
