NUCLEAR ENERGY HUB
Idaho National Laboratory: 6K+ Federal Employees

INL is the nation's premier nuclear energy research facility and a cornerstone of the U.S. Department of Energy. With 6K+ employees earning $80K-$150K, INL creates a deep pool of high-income, federally-employed tenants with exceptional job security and long tenure.

BEST COST SEG RATIOS
80% Building Value + 0.48% Property Tax

Idaho Falls has the best cost seg fundamentals in Idaho. The 80% building-to-value ratio means more of your purchase price is depreciable, and the 0.48% property tax keeps recurring costs minimal. On a $320K property, this combination yields an 820% Year 1 ROI on the cost seg study.

YELLOWSTONE GATEWAY
2 Hours to Yellowstone + Grand Teton National Parks

Idaho Falls is the closest city with full services to Yellowstone and Grand Teton National Parks. Summer tourism creates seasonal STR demand that supplements year-round LTR income from INL employees. The dual-market opportunity enhances total returns.

What Gets Reclassified

A cost segregation study identifies building components that can be depreciated over 5, 7, or 15 years instead of the standard 27.5 or 39 years. In Idaho Falls, typical reclassification rates are 25-38% of building value.

Avg. ROI

The math: A $320,000 property with 80% building value and 30% reclassification yields ~$28,416 in Year 1 federal tax savings at the 37% bracket — significantly more ROI than traditional studies costing $5,000-$10,000+.

Housing Stock Advantage

With a median build year of 1994, Idaho Falls's housing stock has identifiable components (HVAC, electrical, plumbing, landscaping) that are strong candidates for accelerated depreciation.

Full Conformity
Idaho Bonus Depreciation Conformity

Idaho fully conforms to federal bonus depreciation under IRC Section 168(k). The state allows the same accelerated depreciation deductions as the federal return, making cost segregation studies equally effective at both the federal and state level.

What This Means for Idaho Falls Investors: Full conformity means your cost segregation study generates both federal AND state tax savings simultaneously. At a 5.695% flat state rate, Idaho provides meaningful incremental state savings on top of substantial federal deductions — with zero addback or modification required.

Federal vs. ID Depreciation Timeline
PeriodFederal TreatmentID State Treatment
Year 1100% bonus depreciationFull conformity — same as federal
Years 2+Standard MACRS schedulesFull conformity — same as federal
Section 179 Expensing
State ConformityLimited

Idaho conforms to federal Section 179 expensing limits. Combined with full bonus depreciation conformity, Idaho investors get clean, straightforward depreciation treatment with no state-level adjustments or addbacks.

Key Takeaway

A $440K Boise property with a $317K depreciable basis and 30% cost seg reclassification yields ~$35,200 in federal tax savings plus ~$5,420 in state savings in Year 1. Full conformity means one study, two levels of savings — and Idaho's 0.43% property tax keeps recurring costs minimal.

Bottom Line

Idaho is one of the best states for cost segregation. Full federal conformity + a meaningful 5.695% flat state rate + the 4th-lowest property tax in the nation = maximum depreciable basis with dual-level savings and minimal recurring costs.
