A short-term rental is a furnished residential property rented to guests for stays shorter than 30 days, typically booked through a platform such as Airbnb or Vrbo. In United States tax terms, the threshold that actually matters is seven days: if the average stay across the year is seven days or less, the property is not treated as a rental activity under the passive activity rules.

The three thresholds that define the category
The phrase gets used loosely. Three separate lines matter, and they do different jobs.
| Threshold | What it controls |
|---|---|
| 7 days or less average stay | Federal tax treatment. Removes the automatic passive classification under Treas. Reg. 1.469-1T(e)(3). |
| Under 30 days | The common regulatory and platform definition. Most city ordinances use this line. |
| 30 days or more | Generally a mid-term rental. Different lease law, different tax treatment, lower turnover. |
Why the seven-day line matters more than the others
A property whose average stay exceeds seven days is a rental activity, and rental activities are passive by default. Passive losses generally offset only passive income, so depreciation on that property does nothing for a W-2 earner's current tax bill.
Cross the seven-day line and the property stops being a rental activity for those purposes. Add material participation and the loss becomes non-passive, which is what lets it offset wage and business income. That single distinction is the reason high earners buy short-term rentals rather than long-term ones.
What a short-term rental is not
- Not a hotel. It is residential property under residential financing and residential zoning, which is precisely why local regulation is contested.
- Not passive income. It is an operating business with 60 to 120 turnovers a year. See is Airbnb passive income.
- Not automatically tax-advantaged. The seven-day average is necessary but not sufficient. Material participation is the second gate.

Frequently asked questions
What counts as a short-term rental for tax purposes?
For federal tax purposes the test is whether the average period of customer use is seven days or less across the year. If it is, the activity is not treated as a rental activity under the passive activity rules, which is the first condition for using a loss against non-passive income.
What is the difference between a short-term rental and a mid-term rental?
Short-term rentals run stays under 30 days and often average under seven. Mid-term rentals are furnished stays of 30 days or more, typically to travelling professionals. Mid-term rentals have lower turnover cost and steadier occupancy, but they fall back into passive rental treatment for tax purposes.
Is a short-term rental a business or an investment?
Operationally it is a business, with guest service, pricing, cleaning, and maintenance. For tax purposes it can be treated as a non-passive trade or business if the seven-day average is met and the owner materially participates. Talk to a CPA about your specific facts.
