Value Props for Investors

TECH HQ
Micron Technology: America's Only DRAM Manufacturer

Micron Technology is headquartered in Boise and is the only U.S.-based DRAM memory manufacturer — a strategic national asset. Micron's 7K+ local employees earn $80K-$180K, creating a premium tenant pool. The CHIPS Act is driving billions in additional semiconductor investment.

FASTEST GROWING
#1 Population Growth Rate in America (1.4%/Year)

Idaho is the fastest-growing state by population per the U.S. Census. Boise is the primary destination, absorbing 25K+ net migrants annually from California, Washington, and Oregon. This sustained in-migration creates a perpetual demand engine for rental housing.

LOW PROPERTY TAX
0.52% Rate — 4th Lowest in the Nation

Idaho's 0.52% effective property tax rate in Ada County is among the lowest in America. On a $440K property, that is just $2,288/year in property taxes — compared to $8,140 in Texas or $5,720 in North Carolina. Lower recurring costs mean stronger cash flow and faster payback on cost seg investments.

Cost Segregation & Tax Rules in Boise, ID

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 Boise, typical reclassification rates are 25-38% of building value.

Avg. ROI
10-40x

The math: A $440,000 property with 70% building value and 30% reclassification yields ~$34,188 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 2002, Boise'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 Boise 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.

Idaho's rapid property appreciation has created assessment challenges. The Board of Equalization process is accessible and free. Given the state's explosive growth, assessments can jump significantly year-over-year — making appeals particularly valuable for investment properties in fast-appreciating markets like Boise and Coeur d'Alene.

Cost Seg + Insurance Connection

Idaho's remarkably low insurance costs ($1,200/year average — 48% below national average) are a significant cash flow advantage. A cost segregation study provides component-level documentation that supports accurate replacement cost estimates, ensuring you are neither over- nor under-insured as wildfire risk repricing reshapes the Idaho insurance market.
