Vacation Home Tax Treatment: Allocation, Losses, and Sale Rules

Vacation home tax treatment turns on a single question the IRS asks every year: how many days did you use the property personally, and how many days did you rent it at fair market rates? The answer sorts your property into one of three categories, and each category comes with its own rules for what you report and what you can deduct. Get the count wrong and you can lose thousands in disallowed deductions or owe tax on income you thought was tax-free.

The Three Categories and the Test That Sorts Them

Section 280A of the Internal Revenue Code draws the lines. Your property counts as a “residence” if your personal use exceeds the greater of 14 days or 10% of the days you rented it at a fair price.¹ Rent it 200 days and the 10% threshold is 20, so 20 controls. Rent it 50 days and the 14-day floor applies. You use whichever number is higher.

From that test, three categories emerge. If you rent 14 days or fewer, the income is tax-free and the property stays a personal residence. If you rent 15 or more days and your personal use crosses the residence threshold, you have a mixed-use property with allocated deductions capped at rental income. If you rent 15 or more days and keep personal use at or below the threshold, the IRS treats the property as a rental or investment asset, and losses may offset other income.

What Counts as a Personal Day

Personal use is broader than your own stays. Any day a family member uses the property counts, even if you never set foot inside. Any day you let a friend stay for less than fair market rent counts. So do home swaps with other owners, and stays donated to charity auctions (which the IRS also refuses to treat as a deductible charitable contribution because they represent only a partial interest in the property).¹

Days spent working substantially full-time on repairs and maintenance do not count as personal use, even if family members come along and enjoy the pool. “Substantially full-time” means you are there to fix things, not to squeeze in a weekend while replacing a light bulb. The work must be repair or maintenance rather than a capital improvement. Keep a log, because auditors probe this exception first.²

Renting 14 Days or Fewer: The Augusta Rule

Section 280A(g) contains one of the more generous provisions in the code. If you rent your home for 14 days or fewer during the year, every dollar of that rental income is excluded from gross income.¹ You do not report it. You owe no tax on it. There is no cap on the dollars, only on the number of days. The nickname comes from homeowners near the Masters Tournament in Augusta who rent to spectators each spring.

The trade-off is that you can deduct no expenses tied to that rental activity. Cleaning fees, listing photos, and a property manager’s cut during those 14 days produce no deduction. A day counts as a rental day only if a paying guest actually occupied the home at fair market rates; days the home sat available and empty do not count.²

Precision matters. Rent for 15 days instead of 14 and every dollar of income becomes taxable, and you shift into the mixed-use rules. Keep every rental agreement and mark a calendar for each paid night.

Mixed-Use Homes: Allocation and the Income Ceiling

When you rent for 15 or more days and your personal use crosses the residence threshold, expenses split between rental and personal use. Most vacation-home owners land here.

How to Allocate Expenses

For each deductible expense, multiply by a fraction: rental days over total days the home was used, meaning rental days plus personal days. Rent for 90 days and use it personally for 30, and 75% of each expense is allocable to rental. Days the home sat empty do not enter either side.² The IRS applies the same days-used fraction to mortgage interest and property taxes. Some taxpayers use an alternative Tax Court method that spreads interest and taxes over the full 365 days, producing a smaller rental allocation. The IRS does not endorse that approach in its publications, and using it raises audit risk.³

The Cap and the Order of Deductions

Total rental deductions for a mixed-use home cannot exceed gross rental income. No paper losses. When your rental share of expenses runs higher than income, the excess carries forward and stays tied to the same property in future years.²

Expenses come off in a set order: mortgage interest and property taxes first, then operating expenses like utilities and repairs, and depreciation last. Because depreciation sits at the back of the line, it is the first thing pushed into carryforward when income runs thin. A dedicated bank account for rental deposits and property expenses makes filing far easier.

Rental-Focused Properties: Losses and Depreciation

Keep personal use at or below the greater of 14 days or 10% of rental days, and the property becomes a rental or investment asset rather than a personal residence. Deductible expenses can then exceed rental income, potentially producing a loss you can use against other income.⁴

Passive Activity Loss Limits

Rentals are generally passive activities, so losses only offset other passive income. Owners who actively participate in managing the property get an exception: up to $25,000 of rental losses against non-passive income like wages. That allowance phases out starting at $100,000 of modified adjusted gross income and disappears entirely at $150,000.⁵ Active participation is a lower bar than material participation: approving tenants, setting rental terms, and making repair decisions all qualify.

A separate exception releases losses from the passive category for real estate professionals who spend more than half their working hours and at least 750 hours a year in real property businesses.⁶ This rarely helps an owner with a full-time day job.

Depreciation

Residential rental property depreciates over 27.5 years on the straight-line method. Land does not depreciate, so you must separate the building’s cost basis from the land value at acquisition. Improvements you make later get their own 27.5-year clock starting when they are placed in service.² The deduction is valuable while you hold the property, and it comes back at sale, discussed below.

Document your profit motive if you plan to claim losses. Listings on rental platforms, competitive pricing, professional financial records, and a property management agreement all help. A property that loses money year after year with no effort to fix that invites scrutiny.

Mortgage Interest and Property Tax Deductions

Whether or not you rent the place, two itemized deductions on Schedule A are available: mortgage interest and property taxes.

Mortgage Interest

Interest is deductible on up to $750,000 of combined mortgage debt across your primary home and one second home, for loans taken out after December 15, 2017. Older mortgages may still qualify under the prior $1 million cap on the original loan balance. The loan has to be secured by the property, and your lender should send Form 1098 each year documenting the interest paid.⁷

Home equity loan or line-of-credit interest is deductible only when the borrowed funds went to buy, build, or substantially improve the home securing the loan. A HELOC on your vacation home used to pay off credit cards produces no deduction. The same HELOC used to renovate the kitchen does, and the borrowed amount counts toward the $750,000 cap.⁸

Property Taxes and the SALT Cap

Property taxes on a vacation home fall under the state and local tax deduction on Schedule A. Starting in 2025, the SALT cap rose to $40,000 ($20,000 for married filing separately) from the $10,000 limit that applied in 2018 through 2024. The cap and its income thresholds increase 1% annually through 2029. For taxpayers with modified adjusted gross income above $500,000 ($250,000 married filing separately), the cap phases down but never drops below $10,000.⁹ The cap covers state income taxes plus property taxes across every property you own, so a large state income tax bill leaves less room for the property tax piece.

The 3.8% Surtax on Rental Income

Rental income can trigger the Net Investment Income Tax, a 3.8% surtax that applies when modified adjusted gross income exceeds $250,000 married filing jointly, $200,000 single, or $125,000 married filing separately. It hits the lesser of your net investment income or the MAGI amount above the threshold.¹⁰ Net rental income counts as investment income for this purpose. The exception for an active trade or business rarely covers passive rental activity.

Selling the Property

Tax treatment at sale depends on how you used the property. A purely personal vacation home is subject to capital gains tax on any profit with no special exclusion. A rental faces capital gains tax plus depreciation recapture.

Depreciation Recapture

Every dollar of depreciation you claimed (or should have claimed) on a rental vacation home is taxed at up to 25% when you sell, regardless of your regular capital gains rate.¹¹ This is called unrecaptured Section 1250 gain. Claim $50,000 of depreciation over the years and that $50,000 gets the 25% treatment on sale, even if the rest of your gain qualifies for the lower long-term capital gains rate. Gain above the depreciation amount is taxed at the ordinary long-term capital gains rate.

Converting Before Selling

Some owners move into a vacation home to claim the Section 121 exclusion, which shelters up to $250,000 of gain ($500,000 married filing jointly). You must have owned the home for at least two of the five years before the sale and lived in it as your primary residence for at least two of those five years. The two periods do not have to overlap, but both must be met, and the exclusion is available only once every two years.¹²

Even when you qualify, the exclusion does not cover gain attributable to periods after 2008 when the property was not your principal residence. If you owned a vacation home for ten years and lived in it as your main home only for the final two, a portion of the gain tied to the earlier non-qualifying years stays taxable. Run the math before assuming the full exclusion applies.

Section 1031 Exchanges

A Section 1031 exchange lets you defer capital gains by swapping one investment property for another of like kind. Vacation homes used primarily for personal purposes do not qualify, but Revenue Procedure 2008-16 provides a safe harbor. Your property qualifies if you owned it for at least 24 months before the exchange and, in each of the two preceding 12-month periods, rented it at fair market rates for 14 days or more while limiting personal use to the greater of 14 days or 10% of rental days.¹³ The replacement property must meet the same standards for the 24 months after the exchange. Falling short of these thresholds does not automatically kill the exchange, but you lose the safe harbor and invite closer IRS review.
