Short-Term Rental Taxes in Wisconsin: What STR Investors Must Know About Bonus Depreciation
3.54–7.65% graduated state income tax | Wisconsin does NOT conform to federal bonus depreciation | 5% state sales tax + county room tax | Top markets: Door County, Lake Geneva, Wisconsin Dells, Apostle Islands | Work with a WI CPA on depreciation planning
Wisconsin offers some of the Midwest's most desirable vacation property markets: the dramatic limestone cliffs and cherry orchards of Door County, the elegant resort community of Lake Geneva (Chicago's classic summer escape), the water parks and family entertainment of Wisconsin Dells, and the remote wilderness of the Apostle Islands on Lake Superior. For STR investors, Wisconsin presents a moderate-to-high tax burden with one important complication — limited bonus depreciation conformity — that requires careful planning.
Wisconsin State Income Tax on STR Rental Income
Wisconsin's graduated income tax tops out at 7.65% for income over $304,170 — making it one of the higher state income tax environments in the Midwest. Most STR investors with significant rental income will find themselves in the 5.3% or 7.65% bracket. Wisconsin does not have a special rate for investment income; all income is taxed at ordinary rates. Non-resident owners of Wisconsin STR properties file Wisconsin Form 1NPR and pay Wisconsin income tax on Wisconsin-source income at the same rates.
IMPORTANT: Wisconsin's Limited Bonus Depreciation Conformity
Wisconsin maintains its own depreciation system, based on pre-TCJA (2017 Tax Cuts and Jobs Act) federal rules. Wisconsin generally does not allow the enhanced 100% bonus depreciation that applies federally. Instead, Wisconsin requires assets to be depreciated over their regular useful lives under Wisconsin's modified ACRS rules.
The practical impact: in the year you claim large bonus depreciation deductions on your federal return via cost segregation, you must add back the excess depreciation on your Wisconsin Form 1 and recalculate using Wisconsin's depreciation rules. Your Wisconsin taxable income can be substantially higher than federal in the first year, followed by lower Wisconsin income in subsequent years as the Wisconsin depreciation catches up. This is a timing difference, not a permanent loss — over the full asset life, total Wisconsin depreciation equals total federal depreciation. Work with a CPA who understands Wisconsin's depreciation regime to properly model the multi-year Wisconsin tax impact.
