Cost Segregation Study in Idaho for Airbnb and Short-Term Rental Investors
Idaho is one of the fastest-growing states in the country, and its vacation rental market is booming. Sun Valley and Ketchum offer world-class skiing and summer recreation. Coeur d'Alene is a premier lakeside destination in the Idaho Panhandle. McCall attracts visitors year-round for outdoor adventure. Boise's rapid growth has created strong urban STR demand from relocating professionals and business travelers. Sandpoint, Stanley, and Driggs near Grand Teton round out a state with expanding investor opportunities.
If you own an Airbnb or investment property in Idaho, a cost segregation study can reduce your federal tax liability by accelerating depreciation deductions in year one.

Idaho Tax Landscape for Investors
Idaho has a flat state income tax rate of 5.3 percent for 2026, reduced from 5.695 percent in previous years as part of ongoing tax reform. While not as low as no-income-tax states, Idaho's rate is competitive and continuing to trend downward.
Important note for Idaho investors: Idaho has historically decoupled from some federal bonus depreciation provisions. For the 2026 tax year, Idaho declined to adopt federal bonus depreciation under the Big Beautiful Bill Act. This means on your Idaho state return, bonus depreciation may not apply, and assets must be depreciated over their assigned recovery periods. However, the federal benefit of 100 percent bonus depreciation still applies in full on your federal return. Your CPA will need to maintain separate depreciation schedules for federal and Idaho returns.
Idaho Cost Segregation Example
You purchase a vacation rental in McCall for $550,000. After subtracting land value, your depreciable building basis is $420,000.
Without cost segregation, your annual depreciation deduction is approximately $15,273 per year over 27.5 years.
With a cost segregation study, our engineers identify $125,000 in assets eligible for 5, 7, and 15-year recovery periods. With 100 percent federal bonus depreciation, you deduct the full $125,000 on your federal return in year one.
At a 32 percent effective federal tax rate, that translates to approximately $40,000 in federal tax savings in year one.
Already Own Your Idaho Property? The Look-Back Study
If you have owned your Idaho rental for years using standard depreciation, a look-back study using IRS Form 3115 lets you claim a one-time catch-up deduction for all previously missed accelerated depreciation on your federal return. No amended returns are needed.
