Owning two homes in Connecticut can provide numerous tax advantages for homeowners. Whether it’s a vacation home, an investment property, or simply a second residence, understanding the financial implications of owning multiple properties in Connecticut is crucial. This article will explore the specific tax advantages available to homeowners in Connecticut, such as deductions on mortgage interest and property taxes, considerations for rental income, capital gains exemptions, and property tax benefits.
Tax Deductions
Mortgage Interest: One of the most significant tax advantages of owning two homes is the ability to deduct mortgage interest on both properties. Homeowners in Connecticut can typically deduct interest on up to $750,000 in combined mortgage debt for their primary residence and a second home, assuming these mortgages originated after December 15, 2017. This deduction can result in substantial tax savings, especially for those with significant mortgage balances. For mortgages originated prior to December 16, 2017, the limit is $1 million. It’s important to note that these limits apply to the total mortgage debt for both homes, not each home individually.
Property Taxes: In addition to mortgage interest, property taxes paid on both homes are also deductible in Connecticut. Homeowners can deduct state and local property taxes, but the total deduction for all state and local taxes, including property and income taxes, is capped at $10,000 per tax return ($5,000 if married filing separately). This deduction can be advantageous regardless of whether the second property is a primary residence or a secondary home.

Rental Income Considerations
Many homeowners in Connecticut choose to rent out their second homes to generate additional income. If you rent out your second home, the tax implications depend on the duration of rental activity.
14-Day Rule: If you rent out your second home for 14 days or fewer during the year, the rental income is tax-free. You don’t need to report it to the IRS, and the property is treated as a personal residence for tax purposes. You can still deduct mortgage interest and property taxes under the rules for a second home. This “14-day rule” allows homeowners to enjoy their second home without worrying about tax implications, as long as they keep their rental days below this threshold.
Rental Property: If you rent out your second home for more than 14 days during the year, you must report all rental income and expenses on your tax return. This means you can deduct expenses related to the rental, such as mortgage interest, property taxes, insurance, repairs, and depreciation, but these deductions must be allocated between personal and rental use. The percentage of these costs you can deduct will depend on the percentage of time you rent it out compared to personal use. For example, if you use the property for 30 days and rent it for 120 days, 80% of the expenses would be rental expenses. Any remaining expenses that exceed rental income can be carried over to the next year.
Capital Gains Exemption
When selling a primary residence, homeowners can exclude up to $250,000 of capital gains from their income, or up to $500,000 if married filing jointly. However, this exclusion only applies to the sale of a primary residence. While this exclusion primarily applies to primary residences, strategically managing your properties can yield benefits. If you sell your primary residence after living there for several years and convert your second home into your primary residence before selling it later on, you might be able to take advantage of this capital gains exclusion a second time.
Property Tax Benefits
Connecticut offers several property tax relief programs that can benefit homeowners with multiple properties, such as:
Elderly Tax Relief Program: This program provides property tax relief to eligible seniors based on income and property value, potentially reducing property taxes for both homes.
Local Exemptions or Credits: Some municipalities in Connecticut offer property tax exemptions or credits for veterans or individuals with disabilities.
