How the Park City Nightly Rental Business License regime affects cost segregation strategy: hold-period assumptions, material participation, and which neighborhoods support which license type.
Before the analysis: the underlying numbers this post draws on come from 5 Park City-area properties run through the Cost Seg Smart engine — same engine that produces real customer studies. Median Year-1 federal savings is $90,760 at the 37% top marginal bracket with 100% bonus depreciation. Reclassification ratio ranges 17.3% to 26.9%.
Park City is the cleanest cost-seg market in the Wasatch — and one of the cleanest in the country — for three reasons that don't apply to most ski towns. First, Utah conforms to federal §168(k), so the 100% bonus depreciation that OBBBA permanently restored in 2025 reduces both your federal and your Utah liability in the same year, with no addback. California buyers relocating equity to Park City are getting a real tax-rate uplift, not just a postponement of pain.Second, the property mix is unusually heterogeneous for a ski market. Deer Valley's resort-tier basis is dominated by land — engine reconciliation factors run high and 5-year personal property shows up mostly through FF&E...
The remainder of this section drills into the specifics that matter for regulatory specific. The five fixtures we ran through the engine for Park City span $1,100,000 to $2,400,000 in purchase price across 5 distinct sub-markets — enough variance to draw real conclusions about which scenarios actually produce cost-seg ROI in this market.
Take the Deer Valley Ski-In Condo as our anchor example. Purchase price: $2,400,000. Built 2010, 2400 sqft, CONDO operating as a short-term rental, located in Deer Valley.
The engine determined land allocation of 50.0% using statistical_premium_floor methodology, producing a depreciable basis of $1,200,000. Of that, the engine reclassified $231,564 into 5-year personal property (FF&E, decorative finishes, certain electrical), $75,068 into 15-year land improvements (paving, landscaping, hardscape, site lighting), and the rest into the 27.5-Year Residential Real Property structural category.
That produces a total reclassification ratio of 26.1%. At 100% bonus depreciation and a 37% federal marginal bracket, the illustrative Year-1 federal tax savings is $115,726. That's the headline number for this fixture.
Contrast that with Old Town Mining-Era SFR: $1,650,000 in Old Town, built 1908. Here the engine produced a reclassification ratio of 23.6% — lower than the previous example.
Why? Two reasons. First, the land allocation profile is different — 50.0% here versus 50.0% for the previous example. Second, the engine's treatment of sfr as a furnished short-term rental interacts with the build-year and FF&E density differently across neighborhoods.
The takeaway: in Park City, the per-fixture variance is real. A median number (26.1% reclass) hides meaningful variation across sub-markets and property archetypes.
Utah conforms to federal §168(k), so 100% bonus depreciation under the One Big Beautiful Bill Act applies for both federal AND Utah state tax. There is no state addback. Park City cost-seg deductions reduce both your federal and your Utah income tax liability in the same year.
This affects every cost-seg calculation in Park City. Because Utah conforms, the deduction flows through to your state liability with no friction. Your effective combined federal + state tax rate determines the actual savings dollars.
Park City Nightly Rental Business License. Operating an STR in Park City requires a Nightly Rental Business License from the city's Business Services Office, with a separate Type 1 (residential) or Type 2 (resort/zoned commercial) designation depending on parcel zoning. License renewals are annual; the license is tied to the property, not the operator. Material participation under §469 requires >100 hours of active management AND more than any other person — Park City's professional property-management ecosystem means tracking this carefully matters more here than in markets where owners self-manage. Summit County assessor data is publicly searchable at SummitCountyUtah.gov; we cross-reference recorded sales basis and land allocations against engine outputs as a QC step.
