Owning a second home can blur the line between vacation getaway and rental property. The IRS’s 14-day rule is a key threshold every real estate agent should understand when advising clients on tax implications. Here’s the scoop in a nutshell.
The Magic Number: 14 Days
If your client rents out their vacation home for 14 days or fewer in a year, that rental income is tax-free – it does not need to be reported on their tax return. This is often called the “Masters exemption” (think homeowners near a big event renting for two weeks).
But remember: no taxes, no deductions – if rental days are ≤ 14, you generally can’t deduct rental expenses either. It’s essentially treated as a personal residence during that time.
On day 15, however, the game changes. Rent 15 days or more, and all rental income must be reported to the IRS. In other words, the moment you cross that 14-day mark, it’s a rental property in the IRS’s eyes.
Personal Use vs. Rental Use
It’s not just about days rented – personal use matters too. The IRS defines a property as a “residence” (vacation home) if personal use exceeds 14 days or 10% of rental days (whichever is greater) (irs.gov). If a client stays at their lake cabin for, say, a month but also rents it out, it likely counts as a personal residence. What does that mean? Essentially, limits on deductible losses.
Rental expenses can be written off only up to the amount of rental income when the home is classified as a residence (irs.gov). You can’t generate a tax loss to offset other income in that scenario – extra expenses just carry forward.
On the flip side, if personal use is minimal (e.g. just a week or two and within 10% of rental days), the home might be treated as a full rental property, and normal passive loss rules apply (more on that in a bit).
Splitting Expenses Fairly
When a property serves double-duty (your client vacations there part of the year and tenants occupy it for part), the IRS expects a fair split of expenses. Agents can guide clients to prorate costs by days. For example, if a beach house is rented 80 days and used personally 20 days, 80% of certain expenses (utilities, insurance, maintenance, etc.) could be counted as rental expenses, and 20% as personal (irs.gov).
Mortgage interest and property taxes get divided, too – the rental portion goes on the Schedule E, and the personal portion might still be deductible on Schedule A as part of home ownership (irs.gov).
It’s important to note that only the rental-use portion of expenses is deductible against rental income (irs.gov). Any personal-use portion, like that new deck furniture for the owner’s enjoyment, is not a rental deduction (though personal mortgage interest and property tax may be deductible under homeownership rules up to certain limits).
Advising Clients Intelligently
Real estate agents don’t need to be CPAs, but understanding these basics is gold. For clients who say, “We’d like some rental income but don’t want a hassle,” you might mention the 14-day sweet spot: they could earn some extra cash completely tax-free if they limit rentals to 2 weeks.
This often comes up in Real estate continuing education classes as a savvy tip. On the other hand, if they plan to rent more often (Airbnb all summer, perhaps), prepare them: keep good records, report the income, and enjoy the benefit of writing off expenses proportionally. There’s no one-size-fits-all answer – it depends on their goals.
Are they trying to maximize rental income or just offset the costs of owning a second home? As their agent (and trusted advisor), you can add value by explaining how the “vacation home or rental?” decision isn’t just lifestyle – it has tax wrinkles too.
Encourage them to consult a tax professional for detailed guidance, but with these tips, you’ve given them a head start. After all, part of Real Estate CE (continuing education) is staying informed so you can keep clients informed as well!
