Bonus depreciation (IRS §168(k)): a federal tax provision letting investors deduct 100% of qualifying property costs in the year the property is placed in service. For short-term rentals, the deductible portion is the 5-year (personal property) and 15-year (land improvements) components of the total purchase price. See what bonus depreciation is for short-term rentals for the full explainer.
Bonus-eligible %: a DepreciMax metric — the share of a property's purchase price that classifies as 5-year or 15-year property under §168(k), and is therefore 100% deductible in Year 1. Kalispell / Flathead's market-median bonus-eligible % is 23.1% — meaning a typical $745k Kalispell / Flathead STR generates ~$172k of Year-1 deduction.
The 7-day STR rule: to unlock the "STR loophole" — where bonus depreciation offsets W-2 and other ordinary income, not just passive rental income — the property must average a guest stay of 7 days or less and the owner must materially participate. See how to qualify for the STR loophole.
Kalispell requires an administrative conditional use permit for all STRs under Title 20 Chapter 22, plus building/health inspections and state accommodation license; residential-zone density effectively capped at ~2% of housing units.

Montana State Conformity — Full
Montana fully conforms to federal §168(k). Investors capture the entire Year-1 federal deduction plus Montana state-level tax savings against Montana's 5.9% top marginal rate. The state layer is additive, not subtractive — this is the ideal scenario for bonus depreciation math.
Why Kalispell / Flathead ranks #43 for STR bonus depreciation
Kalispell / Flathead ranks #43 because it combines Glacier National Park tourism demand with Montana's full §168(k) conformity. Inventory skews toward large log homes and cabins with heavy FF&E and outdoor amenity stacks — the exact profile that pushes bonus-eligible % above the national median.
What drives Kalispell / Flathead's bonus depreciation profile?
Kalispell / Flathead STRs lean on the amenity categories the IRS classifies as 15-year land improvements — hot tub or spa, fire pit / fire feature, outdoor deck or wraparound porch, and outdoor kitchen / bbq area. All 100% bonus-eligible in Year 1 under §168(k). Combined with land ratios that stay in the 20–26% band (leaving 74–80% of purchase price as depreciable basis), that amenity density pushes the market-median bonus-eligible % to 23.1%.

How to use this data to underwrite a Kalispell / Flathead STR deal
The market-median numbers on this page are a screening tool, not a final answer. Here's how STR investors and their CPAs actually convert a market rank + median bonus-eligible % into an underwriting number for a specific offer.
Screen the deal against the market median. If a Kalispell / Flathead listing is priced within the p25–p75 range ($558k–$906k) and looks like a typical mountain STR, the market-median 23.1% bonus-eligible is a defensible screening estimate. That gives you a Year-1 deduction range you can plug into an initial underwriting model in about 60 seconds — before you invest CPA time or offer-drafting effort.
Adjust up or down based on amenity signals. Kalispell / Flathead properties with a full outdoor stack trend toward the Diamond tier at 24%+ bonus-eligible. Properties with minimal outdoor amenities — condos, plain subdivision homes without hot tubs / decks / fire pits — trend toward the Bronze tier at 18–20%. Use the amenity checklist to categorize before you commit.
Model the offer with the deduction baked in. Take the estimated Year-1 deduction × your federal marginal rate (typically 37% for high-earner STR investors) = federal tax savings. Add this to your effective Year-1 cash-on-cash return. On a $745k Kalispell / Flathead STR at 23.1% bonus-eligible, that's ~$64k in federal savings plus ~$9k in Montana state savings at 5.9% top marginal.
Verify with a $99 property-level report before you sign. Once you're past screening and preparing to make an offer, run the specific property through DepreciMax's photo-analysis pipeline. The $99 report tightens the estimate to a single number, line-items the 5-year / 15-year / 39-year breakdown, and delivers a calibrated Year-1 number closely calibrated to a formal cost segregation study's bonus-eligible %. Your CPA can build the return directly from this output; a formal engineered study (typically $5,000–$8,000) is only necessary post-closing for IRS-defensible filing on very large deductions or high-scrutiny audit risk.
