Maximizing Your Rental Property Tax Benefits: A Practical Guide for Wisconsin Landlords

Owning rental property can be a powerful wealth-building tool, but the tax rules can feel overwhelming. The good news is that with some basic education and good planning, you can turn the tax code into an asset instead of a headache. Whether you own a single duplex or several units around Green Bay, understanding how rental income is taxed helps you keep more of your cash flow.

First, rental income is generally taxable in the year you receive it, including rent, advance rent, and certain nonrefundable deposits. On the flip side, you can deduct ordinary and necessary expenses for managing and maintaining the property. Common deductions include mortgage interest, property taxes, insurance, repairs, utilities you pay, property management fees, legal and accounting fees, and mileage driven for trips to and from the property. Good recordkeeping is critical for accurate tax preparation and for backing up your numbers if the IRS ever asks questions.

A big advantage for rental owners is depreciation. Depreciation lets you recover the cost of the building (not the land) over 27.5 years for residential real estate. On top of this standard schedule, there may be options for bonus depreciation or cost segregation studies to accelerate certain components like appliances, flooring, or HVAC. Accelerated depreciation can increase current deductions, but it also affects your gain and “depreciation recapture” when you sell, so it should be planned thoughtfully.

One of the most confusing areas is the difference between repairs and improvements. Repairs keep the property in its ordinary efficient operating condition (like fixing a leaky faucet or patching a small section of drywall) and are usually deductible in the year you pay them. Improvements add value, prolong the life of the property, or adapt it to a new use (like a new roof, full kitchen remodel, or adding a deck). These typically must be capitalized and depreciated. Misclassifying these is a common pitfall that can cause issues if your return is examined.

Another major concept is passive activity versus material participation. Most long-term rentals are considered passive activities by default, meaning your losses are usually limited to offsetting other passive income. If your income is below certain thresholds and you or your spouse actively participate (making management decisions, approving repairs, screening tenants, etc.), you may qualify for the “up to $25,000 rental real estate loss allowance” that can offset non-passive income like wages. If you meet stricter tests and qualify as a real estate professional and materially participate in your rentals, your rental activity may be treated as non-passive, potentially unlocking larger loss deductions.

Short-term rentals, including Airbnb- and VRBO-style operations, add another layer. Depending on the average length of stay and your level of involvement, a short-term rental may not be treated as a passive rental at all, but more like an active business. In some cases, this can allow you to use losses against other income if you materially participate, but there can also be self-employment tax and other considerations. Getting this classification wrong is another frequent pitfall.

From an entity standpoint, many landlords hold properties in LLCs for liability reasons, but for tax purposes an LLC can be disregarded, a partnership, or an S corporation depending on the structure. Each option has pros and cons. The choice can also interact with state-specific rules, like Wisconsin’s pass-through entity tax election, which may be valuable for some owners in De Pere and surrounding communities. This is an area where personalized advice really pays off.

Finally, as your portfolio grows, planning ahead for estimated taxes, retirement contributions, and eventual exit strategies (including 1031 exchanges and timing of sales) can smooth out cash flow and reduce surprises. Coordinating your rental strategy with a holistic look at your overall financial picture is one of the best reasons to work with a CPA who understands local markets like Green Bay and De Pere.

If you own rental property or are thinking about buying your first one, proactive tax preparation and planning can make a significant difference. The rules are complex, but with the right guidance, they become a toolbox instead of a trap.
