The 14-Day Rule: When Your Airbnb Income Is Completely Tax-Free

Most people assume all rental income is taxable. But IRC § 280A(g) contains a remarkable exception: if you rent your home (or vacation property) for 14 days or fewer during the year, you don't have to report that income at all. It's completely excluded from gross income — no Schedule E, no Schedule C, nothing.

The Statutory Language

Section 280A(g) states that if a dwelling unit is rented for fewer than 15 days during the taxable year, the gross income from the rental is not includible in gross income and no deductions (other than mortgage interest and property taxes, which remain itemizable) are allowed. It's a clean exclusion.

Who This Applies To

The 14-day rule applies to a dwelling unit that is also used as a personal residence during the year. If you rent your primary home for 14 days while you're on vacation, that income is tax-free. If you own a vacation property that you personally use AND rent out, and you keep the rental days to 14 or under, the rental income is excluded.

This does not apply to a property that is used exclusively as a rental (no personal use). In that case, you're clearly in the rental business and all income is taxable under the normal rules.

The Trade-Off: No Deductions

The 14-day exclusion is a one-way door. If you use it, you cannot deduct any rental-related expenses against the excluded income. Mortgage interest and property taxes remain deductible as personal itemized deductions (subject to TCJA caps), but operating expenses like cleaning fees, platform fees, and utilities are not deductible.

For most active STR investors with material participation, maximizing rental days — not minimizing them — generates more economic value through accelerated depreciation and W-2 income offsets. The 14-day rule is generally most valuable to incidental landlords (homeowners renting a primary residence occasionally) rather than active STR operators.

The Vacation Home Rules (When You Exceed 14 Days)

Once you exceed 14 rental days in a year, you lose the § 280A(g) exclusion and enter the vacation home rules. The critical question becomes: how many days of personal use did you have?

If personal use exceeds the greater of 14 days OR 10% of the days the property is rented at fair market value, the property is treated as a vacation home. This limits your deductions: expenses allocable to the rental portion cannot exceed rental income (no paper loss is allowed). For most STR investors pursuing the STR tax loophole, this is a major problem — which is why keeping personal use days below the 14-day / 10% threshold is critical.

Counting Personal Use Days

Personal use days include days the property is used by you, family members (at below-market rates), or anyone under a reciprocal use arrangement. Days spent doing legitimate repair and maintenance work do not count as personal use days — but the work must be substantial and documented. A weekend where you "happened to stay over while fixing the deck" may not pass IRS scrutiny unless the maintenance work was clearly the primary purpose.
