Arizona's partial decoupling from federal §168(k) creates a Schedule X addback that affects Sedona cost-seg buyers. Engine-derived walkthrough at the 2.5% flat rate with detailed Year-1 and multi-year recovery math.
Before the analysis: the underlying numbers this post draws on come from 5 Sedona-area properties run through the Cost Seg Smart engine, same engine that produces real customer studies. Median Year-1 federal savings is $66,993 at the 37% top marginal bracket with 100% bonus depreciation. Reclassification ratio ranges 17.7% to 26.9%.
Sedona is the most architecturally and visually distinctive STR market in the network, and the cost-seg case is shaped by two interacting factors specific to Red Rock Country. The view-premium scarcity dominates basis allocation in iconic red-rock-view sub-markets. Engine outputs for the Chapel area, Red Rock Loop Road, and view-oriented Uptown Sedona properties run 32–38% land allocation, among the highest in the network, comparable to Deer Valley in Park City and Rosemary Beach on 30A. View-premium land scarcity translates to compressed depreciable basis as a percentage of purchase, which compresses reclassification ratio percentages even when absolute dollar deductions remain...
The remainder of this section drills into the specifics that matter for regulatory specific. The five fixtures we ran through the engine for Sedona span $685,000 to $1,485,000 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 Uptown Sedona Casita STR as our anchor example. Purchase price: $1,185,000. Built 2008, 2100 sqft, SFR operating as a short-term rental, located in Uptown Sedona.
The engine determined land allocation of 22.3% using statistical methodology, producing a depreciable basis of $921,100. Of that, the engine reclassified $171,136 into 5-year personal property (FF&E, decorative finishes, certain electrical), $59,753 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 25.5%. At 100% bonus depreciation and a 37% federal marginal bracket, the illustrative Year-1 federal tax savings is $87,050. That's the headline number for this fixture.
Contrast that with West Sedona Family STR: $825,000 in West Sedona, built 2002. Here the engine produced a reclassification ratio of 26.3%, higher than the previous example.
Why? Two reasons. First, the land allocation profile is different, 21.6% here versus 22.3% 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 Sedona, the per-fixture variance is real. A median number (26.3% reclass) hides meaningful variation across sub-markets and property archetypes.
Arizona partially decouples from federal §168(k). AZ historically required specific addbacks for federal bonus depreciation, with the addback amount recovered over the regular MACRS schedule for state purposes. For 2025+ acquisitions under OBBBA's 100% federal bonus, the practical effect is that a portion of the accelerated reclassification dollars hit an AZ-side timing mismatch, at AZ's flat 2.5% rate, the absolute dollar impact is small. Federal §168(k) at 100% is unaffected; only the AZ-side acceleration is partially deferred.
Decoupling: Arizona's bonus depreciation conformity has been modified multiple times. Verify current-year treatment with your CPA. The federal deduction is unaffected; only the AZ Schedule X reconciliation is the variable.
This affects every cost-seg calculation in Sedona. Because Arizona doesn't fully conform, the federal Year-1 figure shown above is only the federal-only portion. The state benefit is smaller (or different) and your CPA will need to manage the addback at filing time.
City of Sedona maintains an active STR permit regime with annual renewal requirements, density caps in certain residential zones, and compliance triggers (noise complaints, parking violations) that can revoke permits for repeat violations. Yavapai County (Village of Oak Creek) and Coconino County unincorporated areas (Oak Creek Canyon) operate lighter regulatory regimes. STR-intent buyers should verify the property's jurisdiction, Sedona city limits vs Yavapai County vs Coconino County, before underwriting permit availability. Material participation under §469 is achievable for self-managing operators but harder for buyers using full-service property management (Vacasa, Best Western Sedona-affiliated, local operators), document hours contemporaneously. The Arizona Schedule X addback math should be explicit in your CPA workflow given Arizona's partial conformity.
