Door County, WI STR Tax Guide: What Airbnb Hosts Need to Know in 2026
No credit card required
Door County is Wisconsin's premier vacation destination — a peninsula reaching into Lake Michigan with 300 miles of shoreline, five state parks, cherry orchards, and a charming small-town feel that draws Chicago and Milwaukee visitors year-round. STR regulation is lighter than most urban markets, but hosts must navigate Wisconsin's 5% state sales tax, Door County room tax, and Wisconsin's graduated income tax on rental profits.
Wisconsin STR Tax Structure
Wisconsin taxes short-term lodging through its state sales tax system. Rentals of dwelling units for fewer than 30 days are subject to Wisconsin's 5% state sales tax. Door County adds a county room tax on top of the state rate.
| Tax Component | Rate | Notes |
|---|---|---|
| Wisconsin State Sales Tax | 5.0% | All WI STRs |
| Door County Room Tax | ~3.0–5.0% | County-level lodging tax |
| Municipal Room Tax | Varies | Some villages add local levy |
| Combined Rate | ~8–10% | Approximate total |
Airbnb collects and remits Wisconsin state sales tax for platform bookings. Door County room tax collection by platforms may vary — verify with Door County Tourism whether platform collection covers the county room tax for your listing.
Wisconsin State Income Tax
Wisconsin taxes individual income at graduated rates ranging from 3.5% to 7.65%. STR income reported on your federal Schedule C flows through to Wisconsin Form 1 as business income. Wisconsin has its own depreciation rules that may differ slightly from federal rules in some cases — consult a Wisconsin CPA to confirm the right treatment for your property.
Door County STR Regulations
Door County's STR regulations are generally more permissive than those of major urban markets. Wisconsin state law preempts local municipalities from outright banning short-term rentals, which provides a baseline level of access for STR operators. However, individual municipalities within the county (villages, towns, and cities) may adopt their own rules regarding licensing, parking, noise, and occupancy limits.
Most Door County operators need to register for the county room tax license, which also serves as the primary compliance mechanism. Contact Door County Tourism for the current registration process.

ADR: $200–$300/night for standard properties; $300–$500+/night for waterfront, private beach access, or premium views on the peninsula.
Seasonality:
- Summer (July–August): Peak season, highest occupancy, premium rates
- Fall Foliage (October): Strong secondary peak, especially for couples and retirees
- Cherry Blossom Season (May): Meaningful shoulder demand when cherry orchards bloom
- Winter (December–March): Very slow with minimal demand
Waterfront premium: Properties with water views or lake/bay access command 50–100% higher ADRs than comparable inland properties. Green Bay and Lake Michigan shoreline are the most coveted locations.
Key Deductions for Door County STR Hosts
Dock and Waterfront Access Maintenance
Properties with private docks, boat slips, or pier access have significant annual maintenance costs. Dock inspection, winterization, spring installation, and repairs are fully deductible operating expenses. If dock replacement is required, it's a capital improvement depreciated as a land improvement (15-year schedule).
Winterization
Wisconsin winters require significant winterization efforts for vacation properties: draining pipes, protecting exterior fixtures, covering outdoor furniture, and heating system maintenance. These off-season maintenance costs are deductible in the year incurred. Even for vacant periods, expenses directly related to maintaining the property for rental readiness are deductible.
Kayaks, Canoes, and Water Sports Equipment
Providing water recreation equipment dramatically increases booking rates for Door County properties. Kayaks, canoes, paddleboards, and life jackets provided for guest use are deductible business assets. Items costing $2,500 or less per item qualify for immediate expensing under the de minimis safe harbor.
Cherry Orchard and Agricultural Setting
Some Door County STR properties include or are adjacent to cherry orchards and agricultural land. The agricultural atmosphere is a marketing asset. If your property includes productive farmland or orchard trees, consult a CPA on whether any agricultural expenses (tree care, harvest activities) are deductible as business expenses tied to the rental operation.

Door County properties that sit vacant from November through April face 6 months of carrying costs with minimal rental income. Fixed costs (mortgage interest, property taxes, insurance) are deductible in proportion to annual rental days. A property rented 90 days/year can deduct 90/365 = 24.7% of fixed costs. Track every expense year-round, not just during peak season.
