Short-Term Rental Day Count Checker: 14-Day and 7-Day Rules
Answer a few questions about rental days, personal days and average stay to see which IRS rules probably apply to your Airbnb or vacation rental, and when it is worth a closer look. Free, no signup.
The three numbers that decide how a short-term rental is taxed
| Number | Rule | What it changes |
|---|---|---|
| Days rented | Fewer than 15 days, and you use it as a home | The 14-day rule: rent is generally tax-free and not reported, and rental expenses aren't deducted. |
| Personal-use days | More than the greater of 14 days or 10% of the days rented at a fair price | It counts as a home: expenses are split and rental expenses can't create a loss. |
| Average stay | 7 days or less (or 30 days or less with significant personal services) | Not a "rental activity" for the passive loss rules: no $25,000 allowance, but material participation can make losses nonpassive. |
Separately, hotel-style services during stays (daily cleaning or linen changes, meals, concierge) generally move the rental from Schedule E to Schedule C, where self-employment tax applies.
What counts as a personal-use day
- Any day you, a co-owner or a family member uses it, unless a family member pays a fair rent and it is their main home.
- Days rented to anyone at less than a fair rent.
- Days used under a swap arrangement, or donated to a charity auction.
- Not counted: days you spend working substantially full time on repairs and maintenance.

Frequently asked questions
What is the 14-day rule for renting your home?
If you use a dwelling as a home and rent it out for fewer than 15 days in the year, you generally don't report the rental income and don't deduct rental expenses (IRS Pub 527). Mortgage interest and property taxes are still deducted on Schedule A as usual.
How many personal days can I use my Airbnb?
To avoid the vacation-home limits, keep personal use at or below the greater of 14 days or 10% of the days it is rented at a fair price. Above that, it is treated as a home and rental expenses can't create a loss.
What is the 7-day rule for short-term rentals?
If the average guest stay is 7 days or less, the property isn't a "rental activity" under the passive activity rules (IRS Pub 925). The $25,000 rental loss allowance doesn't apply, and losses are passive unless you materially participate.
Does an average stay under 7 days mean I file Schedule C?
Not by itself. Schedule C generally applies when you provide substantial services for guests' convenience, such as cleaning or linen changes during a stay or meals. Otherwise most short-term rentals stay on Schedule E.
What counts as material participation?
The IRS has seven tests. The common ones for rentals: you work 500+ hours on it in the year; you do substantially all the work; or you work 100+ hours and no one else (including cleaners or a co-host) works more. Keep a dated time log.
