Coeur d'Alene, ID STR Tax Guide: What Airbnb Hosts Need to Know in 2026
No credit card required
Coeur d'Alene is northern Idaho's premier lake resort destination — a rapidly growing market driven by Pacific Northwest remote workers, its stunning lake setting, and a position as an affordable alternative to Washington or Oregon lake destinations. Idaho's flat 5.8% income tax is moderate by western states standards, and the combined lodging tax rate of around 9–11% is competitive. The STR market here has expanded significantly as Seattle and Portland transplants discover CdA's value proposition.

Idaho State Income Tax
Idaho taxes individuals at a flat rate of 5.8% for 2026. This replaced Idaho's prior graduated system. STR income flows from your federal Schedule C to Idaho Form 40 as business income. Idaho conforms to federal depreciation rules including bonus depreciation, which allows accelerated deductions on personal property and improvements in the year placed in service.
Coeur d'Alene Market Snapshot
ADR: $200–$300/night for standard properties; $300–$500+/night for lakefront, premium resort-area, and properties with dock or water access.
Demand profile: Summer (June–August) is peak season, centered on lake recreation — boating, paddle sports, and beach access on Lake Coeur d'Alene. The CdA Resort and Ironman Coeur d'Alene triathlon (June) create demand spikes. Winter is modest but growing as the area develops a year-round identity.
Remote worker growth: Coeur d'Alene has attracted significant in-migration from Seattle, Portland, and the Bay Area. This creates longer-stay demand (30+ day bookings) and weekend getaway traffic from neighboring Spokane, WA. The growing year-round population base supports stronger off-season STR demand than traditional resort markets.
Key Deductions for Coeur d'Alene STR Hosts
Lake and Waterfront Access
Properties with dock access, boat slips, or lakefront rights command premium rates. Dock maintenance, annual inspections, water craft storage fees, and lakefront restoration costs are deductible operating expenses.
Water Recreation Equipment
Kayaks, paddleboards, life jackets, and fishing gear provided for guest use are deductible business assets. Items under $2,500 each are immediately deductible under the de minimis safe harbor.
Winter Maintenance
Northern Idaho winters bring significant snowfall. Snow removal, ice management, and winter property maintenance are deductible operating expenses critical for maintaining year-round rental readiness.
Idaho's new flat 5.8% income tax rate is lower than Oregon (up to 9.9%), Washington is 0%, California (up to 13.3%), and Montana (up to 6.75%). For a Coeur d'Alene host with $40,000 in net STR income, the Idaho income tax is approximately $2,320 — among the lower state income tax burdens in the western US.
