For many Wisconsin families, a cabin up north or a lake home is more than an investment. It is where summers are spent and memories are made. Vacation homes also come with their own set of tax rules, which depend largely on how the property is used. A home used only by the family is treated very differently from one rented to guests for part of the year, and the rules change again when the property is sold or passed to the next generation. If you own or are considering a second home, a complimentary, no-obligation wealth and tax review can help you understand how it fits your overall plan.
This guide explains, in general terms, how vacation home tax rules work for personal use, rentals, sales, and family transfers.
Personal Use Only
If the home is used only by you and your family, it is generally treated as a personal residence for tax purposes. Mortgage interest on a second home may be deductible if you itemize, subject to limits that apply to total mortgage debt. Property taxes may be deductible as part of the overall state and local tax deduction, which is subject to its own limit. Many owners find that these deductions provide less benefit than expected because of those limits or because they take the standard deduction.
Wisconsin treats some of these expenses through its itemized deduction credit rather than a deduction, so the state benefit may differ from the federal one.
Renting the Home for a Short Time
A special rule generally allows owners to rent a home for a small number of days during the year without reporting the rental income, as long as the home is also used personally. This can be useful for owners who rent their cabin for a week during a local event or a peak summer period. Because the day limit is set by law, confirm the current rule before relying on it.
Mixed Personal and Rental Use
When the home is rented for more than the short-term limit and also used personally, the tax picture becomes more complex. Expenses generally need to be divided between rental use and personal use based on the number of days in each category. Deductions for the rental portion may be limited to the rental income if personal use exceeds certain thresholds, which can prevent the property from producing a tax loss.
Days spent on repairs and maintenance generally do not count as personal use, but days used by family members, even if they pay rent, may count as personal days unless fair rent is charged and other conditions are met. Keeping a calendar that tracks each day of use is one of the most useful records a vacation home owner can maintain.
Treating the Home as a Rental Property
If personal use is limited and the home is rented regularly, it may be treated primarily as a rental property. Rental income is reported, and expenses such as management fees, cleaning, utilities, insurance, repairs, and depreciation may be deducted. Losses may be limited by passive activity rules, though short-term rental rules and material participation can change how losses are treated. Our guide to real estate professional status tax rules explains how passive loss rules work.
Short-term rentals also bring operational obligations. In Wisconsin, lodging generally requires collecting sales tax and may require local room taxes and licenses. Some rental platforms collect certain taxes for hosts, but owners should confirm what is and is not covered.
Selling a Vacation Home
The home sale exclusion that applies to a primary residence generally does not apply to a vacation home. When a second home is sold, gain is generally taxable, and depreciation claimed during rental years may be subject to recapture. Some owners consider converting a vacation home into a primary residence before selling, but special rules limit the exclusion for periods of nonqualified use. A 1031 exchange may be available for property held for investment, but not for a home used mainly for personal purposes.
Because the tax on a sale can be significant, planning a sale in a year with lower income, or coordinating it with other gains and losses, can make a difference. Our guide to how to reduce capital gains tax covers related strategies, and depreciation recapture explains the rental piece.
Passing the Cabin to the Next Generation
Many Wisconsin families want to keep a cabin in the family. How it passes matters for taxes and for family harmony. Assets inherited at death generally receive a basis adjustment to fair market value, which can reduce capital gains for heirs who later sell. Gifting the property during life generally carries over the original basis. Families also consider ownership structures such as an LLC or trust to set rules for use, expenses, and future buyouts among siblings. These decisions should be made with an estate attorney and tax professional. Our article on capital gains on inherited property explains basis adjustments.

Budgeting for the True Cost of Ownership
Beyond taxes, vacation homes carry ongoing costs that are easy to underestimate: property taxes, insurance, utilities, snow removal, docks and boat lifts, septic and well maintenance, and periodic repairs to roofs, decks, and shorelines. Lake properties in Wisconsin often have additional costs tied to shoreland zoning rules and permits. Owners who rent the property also pay for cleaning, management, and marketing.
A realistic annual budget helps families decide whether a second home fits their plan, how much rental income may offset costs, and how ownership affects other goals such as retirement savings or education funding. For families who share a cabin across generations, a written agreement on how costs are split can prevent disagreements later. Our wealth management approach includes looking at large assets like a second home alongside your broader plan.
Next Steps
A vacation home can be a cherished family asset, and understanding the tax rules helps you keep it that way. Whether your place is up north, on a lake near Madison, or in another state, coordinating use, rentals, and long-term plans can prevent surprises.
To review how a second home fits with your taxes, estate plan, and investments, request a complimentary, no-obligation wealth and tax review.
