Short-term rental loophole: the 7-day average stay test
A rental activity is passive no matter how many hours you put in. The "short-term rental loophole" is the exception in Treas. Reg. §1.469-1T(e)(3)(ii)(A): when the average period of customer use of a property is 7 days or less, renting it is not a rental activity, so it is passive only if you do not materially participate. Below: the rule, how the average is counted, and a sample cabin worked through (4.00 days).
The rule, in the words of the texts
A passive activity is a trade or business in which the taxpayer does not materially participate, and it includes any rental activity (except as provided for real estate professionals in §469(c)(7)). An activity that is not a rental activity under the 7-day or 30-day exception is therefore passive only if you do not materially participate.
Treas. Reg. §1.469-1T(e)(3)(ii): an activity is not a rental activity for the year if (A) the average period of customer use is 7 days or less, or (B) it is 30 days or less and significant personal services are provided by or for the owner. Four other exceptions exist (extraordinary personal services, rental incidental to a non-rental activity, non-exclusive use during business hours, property provided to a partnership); the tools do not assess them.
How the average is counted
- One period of customer use per stay; a stay renewed or extended by the same guest is one period (§1.469-1(e)(3)(iii)(D)).
- For year 2026, count the periods that end in 2026 or are still running on 31 December 2026, with all their days (§1.469-1(e)(3)(iii)(C)).
- Average = days of those periods / number of periods. Days or nights: the text says days; pick one count with your CPA.
Sample data: a cabin in 2026
13 periods of customer use, 52 nights: 4.00 days, so the 7-day test is met. The first stay began in December 2025; it counts in 2026 because it ends there, with all its nights. The last one runs into 2027; it counts in 2026 because it includes 31 December.

What moves the average
- Merging: the two back-to-back bookings by one guest are one 10-night period. Counted separately: 14 periods, 3.71 days.
- Calendar days instead of nights: 5.00 days.
- Longer stays: the sample condo averages 7.75 days, over 7; it can still meet the 30-day number, which only helps with significant personal services.
What the 7-day test does not decide
Material participation (the hours), whether you use the place as a residence (If a passive activity involves the use of a dwelling unit to which §280A(c)(5) applies for the year (a unit used as a residence), the income, deductions, gain or loss allocable to that use are not taken into account under §469 for that year.), grouping several properties into one activity, and anything about depreciation. Run your own export through the export tool and the hours through the hours check.
Frequently asked questions
- What is the short-term rental loophole, explained simply?
- Rentals are passive by definition (IRC §469(c)(2)). A property whose guests stay 7 days or less on average is not a "rental activity" under the regulation, so it is treated like a business: passive only if you do not materially participate.
- What are the short-term rental loophole requirements?
- Per property and year: an average stay of 7 days or less (or 30 days or less with significant personal services), and material participation under one of the seven tests of §1.469-5T(a). And the unit must not be a residence under §280A for that use (§469(j)(10)).
- Where does the IRS say this?
- In the passive activity regulations: Treas. Reg. §1.469-1T(e)(3)(ii) lists the exceptions to rental activity, and §1.469-1(e)(3)(iii) says how the average period of customer use is computed. The material participation tests are in §1.469-5T(a).
- Does the loophole need material participation?
- Yes. The 7-day test only takes the property out of the rental-activity rule; without material participation the activity is still passive (§469(c)(1)). The hours check on this site runs the 100-hour and 500-hour tests.
- Does it cover bonus depreciation or cost segregation?
- Not on this site: the tools stop at the day counts and hours. Depreciation and cost segregation are for your CPA.
