Two Homes, Two Taxes? A Legal Guide to Taxes on Second Homes

For tax reporting and deductions, the IRS classifies a second home as either a personal residence or rental property, depending on how many days you rent it versus live in it personally. Eligible deductions depend on whether the second home is used personally or rented out.

Whether as a homeowner looking to increase rental income or as a home buyer purchasing a vacation property, understanding the tax implications is critical to avoiding surprises at tax time.

What Counts as a Second Home for Tax Purposes?

The Internal Revenue Service (IRS) defines a second home as a personal property that meets the criteria for a dwelling unit, including basic living accommodations such as sleeping, cooking, and bathroom facilities.

• Personal residence criteria. To consider your second home a personal residence for the tax year (with potential tax benefits), you must use the home for at least 15 days or 10% of the days that you rent it out, whichever is greater.
• Rental property criteria. If you rent your home for more than 15 days each year and your personal use of the property does not exceed 14 days per year or 10% of the number of days the home was rented, it is classified as a rental or investment property.

Reporting Rental Income for a Second Home

The classification of your home determines whether you need to report rental income for a second home. This distinction is critical for self-employed individuals who may rely on rental income as part of their overall financial strategy.

• A second home is considered a personal residence. You do not need to report any rental income to the IRS if you rent the home for fewer than 15 days per year.
• A second home is considered an investment or rental property. Rental income must be reported, but you can deduct certain expenses.

It is important to note that tax rules do not allow you to offset W-2 income with rental expenses. For example, you cannot use rental property deductions to reduce income from your full-time job.

Income Tax Deductions and Implications for a Second Home

Understanding the tax deductions and implications for your second home depends on how the property is classified — either as a personal residence or a rental/investment property. The purchase price of the home also affects depreciation deductions over time.

Deductions for Personal Residences

The deductibility of mortgage interest and state and local real property taxes depends on whether the second home is used personally or rented out.

Rental Expenses

You cannot deduct rental-related expenses, such as cleaning, repairs, or maintenance, if the home is not rented.

Mortgage Interest

Assuming you itemize your deductions, mortgage interest paid on a second residence used as a personal residence is deductible as long as the mortgage satisfies the same requirements as your primary home.

For homes acquired before December 15, 2017, the combined acquisition debt limit for your primary and secondary home is $750,000 (or $1 million for older mortgages). Each mortgage must be secured by the home.

Property Taxes

If you own two houses that are considered your personal residence, you’ll owe two sets of property taxes. State and local real estate taxes paid for a second home are generally deductible on your federal taxes (Schedule A for itemized deductions), subject to the SALT cap.

• SALT cap. Under the One Big Beautiful Bill Act of 2025, the total allowed for state and local tax deductions is capped at $40,400 in 2026, with an annual increase of 1% until 2030. After 2030, the cap will return to $10,000 ($5,000 for married couples filing separately).
• Phase-out. The enhanced deduction begins phasing out for taxpayers with MAGI over $505,000, with the phase‑out thresholds adjusted slightly upward each year.

Deductions for Rental or Investment Properties

Second homes, such as a vacation property, can be a valuable source of not only investment income but also tax benefits. If your second home is classified as a rental or investment property, you may qualify for more extensive deductions.

• Tax-efficient income. Offset rental income with deductions. This allows you to collect cash flow with minimal tax liability.
• Rental expenses. Deduct certain expenses related to the rental, such as home improvements, maintenance, cleaning, and repairs.
• Depreciation. The purchase price of the home can be depreciated over 27 years, which reduces your taxable rental income.

• Property taxes. You may be able to deduct all or a portion of the property without being subject to the SALT cap, depending on the classification of the property.
• Mortgage interest. It may be deductible, but the amount may depend on how much the property is rented versus used personally.

To take advantage of these deductions, report rental property income, deductions, and depreciation on Schedule E of your tax returns.

Tax Implications of Renting Out Your Vacation Home

If you rent out your second residence, and you use it personally, additional rules may apply. The amount of time you use the property for personal use versus renting it out can affect the deductibility of expenses, such as mortgage interest and property taxes.

Another aspect of mixed use to consider is that short-term rentals may have different implications compared to long-term leases.

Understanding the distinctions among personal residences, rental property, and mixed-use property can help you better plan for the tax implications of owning a second home and taking advantage of potential benefits.

• Personal residences. Limited deductions are available, primarily for mortgage interest and property taxes, subject to caps and limitations.
• Rental/investment properties. Broader deductions are available, including rental expenses and depreciation, which can significantly reduce taxable income.
• Mixed use. The balance of personal and rental use impacts the deductibility of expenses, making professional tax advice essential.

A tax professional, such as a CPA, can help determine your tax liability depending on your individual circumstances and help you navigate tax law.

How Are You Taxed When You Sell?

Selling a second home can trigger capital gains taxes. Although the capital gains tax rate on property held more than one year is generally lower than the ordinary income tax rate, it can still be a significant expense.

There are strategies to reduce or defer taxes, including:

• Primary residence exclusion. Living in the property for at least two years out of the five years before the sale, and meeting all other tests, allows you to potentially exclude gains under the primary residence tax rules.
• 1031 exchange. Defer capital gains by reinvesting in another like-kind property as part of a 1031 exchange.

Get Tax Advice

Owning a second home can be rewarding. It can be a welcome respite from everyday life and allow you to spend meaningful time with loved ones.

But if you rent out your property, it can create tax liabilities. It’s recommended that you engage in tax planning with your financial advisor or other professional. They can review your situation and provide guidance to ensure compliance and maximize benefits.
