Understand vacation home tax rules, including the 14-day and 10% test, the under-15-day rental exception, expense limits, and reporting.
Vacation home rules determine how to report income and allocate expenses when a dwelling is rented and also used personally. The central question is whether personal use exceeds the greater of 14 days or 10% of fair-rental days. A separate rule generally excludes rental income when a home is rented for fewer than 15 days during the year.
"Vacation home" is a convenient label, but the rules can apply to a house, apartment, condominium, mobile home, boat, or similar dwelling with basic living accommodations. They can affect a second home, a room in a primary residence, or a short-term rental that the owner uses between guests.
If the property is used as a home and rented for fewer than 15 days during the year, rental income generally is not reported and rental expenses generally are not deductible. Otherwise allowable personal deductions, such as qualifying mortgage interest or real property tax, may still be considered under their own rules.
This is sometimes called the "Masters exception," but it is not a special short-term-rental business election. The count is rental days for the year, not average guest stay. Fourteen rental days may qualify; 15 do not.
When the dwelling is treated as a residence and rented at least 15 days, report all rental income and allocate expenses between personal and rental use. Rental deductions are generally limited so they do not create or increase a net rental loss from the property. Certain otherwise allowable expenses are applied in an ordering framework, and disallowed amounts may carry forward subject to future income and use.
This limitation is distinct from passive-loss suspension. A vacation-home carryforward should not be merged with basis, at-risk, or passive-activity carryforwards.
If personal use does not exceed the greater of 14 days or 10% of fair-rental days, the dwelling is generally not treated as a residence for this rule. Rental income and expenses are reported under the ordinary rental framework. A loss may be possible, but basis, at-risk, passive activity, and other limitations still apply.
Consider a property with 240 fair-rental days and 20 personal-use days. Ten percent of 240 is 24. Because the greater threshold is 24 and 20 days do not exceed it, the property is not treated as used as a residence.
Suppose instead the owner has 30 personal-use days. She exceeds the 24-day threshold, so the property is treated as a residence. Because it was rented for more than 14 days, she reports the rent but applies the mixed-use allocation and income limitation.
Personal-use days can include use by the owner, co-owners, specified family members, home-swap participants, and below-market renters. Substantially full-time repair and maintenance days generally are excluded. Vacant days available for rent do not enter the fair-rental-day denominator.
Report gross rent, advance rent, retained deposits that become income, cancellation payments, and other amounts received for use of the property. Then identify direct rental expenses and allocate shared expenses.
Common shared costs include:
Do not depreciate land. Improvements generally are capitalized and recovered over the applicable period rather than deducted as repairs. Expenses incurred only for personal use are not rental deductions.
Allocation can be technical. Tax rules and case law may produce different approaches for mortgage interest and property taxes than for operating expenses. A simple "rental days divided by 365" formula should not be applied blindly to every line.
Rental real estate with customary landlord services generally appears on Schedule E. Substantial services primarily for guest convenience may support Schedule C reporting and possible self-employment tax. The reporting schedule does not decide whether the dwelling is used as a residence or whether its losses are passive.
Tax software should retain worksheets showing day counts, allocation, depreciation, current deductions, and any vacation-home carryforward. The face of Schedule E may not reveal the entire limitation.
Apply the vacation-home limitation before assuming a rental loss reaches Form 8582. An expense disallowed because the property was used as a home is not the same as an otherwise allowable loss suspended under the passive activity rules.
For a short-term rental, average customer use may remove the activity from the Section 469 rental definition. The owner must then analyze material participation. That result still does not override the vacation-home personal-use calculation.
Using a property as both a home and a rental can affect basis, depreciation recapture, loss treatment, and the home-sale exclusion. Depreciation allowed or allowable for rental periods generally reduces adjusted basis and may be taxable on sale even if the owner failed to claim it.
When a former home becomes a rental, depreciation basis generally starts with the lower of adjusted basis or fair market value on the conversion date. Records should preserve the original purchase allocation, improvements, conversion-date value, depreciation, and periods of qualified and nonqualified use.
California generally starts with the federal rental framework, but federal and state depreciation may differ. California does not conform to every federal acceleration provision, so the deductible amount, carryforward, adjusted basis, and gain on sale can diverge. Schedule CA and California depreciation forms may be needed.
Local permitting and transient occupancy tax requirements are separate. Compliance with a city's short-term-rental ordinance does not determine federal vacation-home treatment.
Heath Income Tax can help vacation-home owners classify use days, allocate expenses, preserve carryforwards, and plan for federal and California sale consequences.
Is rental income tax-free if I rent my home for exactly 14 days?
It may be excluded if the dwelling is used as a home and total rental use is fewer than 15 days. Other facts still matter.
Can I deduct a vacation-home rental loss against wages?
Often not when the dwelling is treated as a residence because deductions are generally limited to rental income. If it is not treated as a residence, separate passive-loss rules determine whether a loss can offset other income.
Does listing the property all year count as rental use?
No. Fair-rental days generally are days actually rented at a fair price, not merely available days.
