TOURISM GATEWAY
14M+ Annual Visitors to Black Hills Region

Mount Rushmore, Badlands National Park, Crazy Horse Memorial, Custer State Park, and Deadwood draw 14M+ visitors annually. Rapid City is the primary lodging hub, creating exceptional STR demand from May through September with nightly rates that can exceed $200 during peak season.

MILITARY ANCHOR
Ellsworth AFB: B-1B Bomber Wing + B-21 Raider

Ellsworth Air Force Base is home to the 28th Bomb Wing and is slated to receive the next-generation B-21 Raider bomber — a multi-billion dollar investment that ensures the base's long-term viability. Military BAH provides government-guaranteed rent for stable LTR income year-round.

ZERO STATE TAX
No Income Tax on STR or LTR Income

South Dakota's zero state income tax means every dollar of rental income and cost segregation savings is yours to keep. On a $310K property, that is $26.8K in clean federal savings in Year 1 — and STR income from tourism is taxed only at the federal level.

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

Avg. ROI

The math: A $310,000 property with 78% building value and 30% reclassification yields ~$26,840 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 1989, Rapid City's housing stock has identifiable components (HVAC, electrical, plumbing, landscaping) that are strong candidates for accelerated depreciation.

N/A — No State Income Tax
South Dakota Bonus Depreciation Conformity

Because South Dakota has no state income tax, there is no state-level depreciation deduction or conformity issue. Federal bonus depreciation under Section 168(k) applies in full and there is no state tax return to worry about.

What This Means for Rapid City Investors: South Dakota is one of the most favorable states for cost segregation. Your entire tax benefit comes from federal savings, with zero state-level complications. No addback, no phase-out, no conformity issues — just clean, immediate federal deductions.

PeriodFederal TreatmentSD State Treatment
Year 1100% bonus depreciationN/A — No state income tax
Years 2+Standard MACRS schedulesN/A — No state income tax
Section 179 Expensing
State ConformityLimited

No state income tax means Section 179 operates at the federal level only in South Dakota. With no state tax to offset, SD investors maximize their retained cash flow from federal deductions.

Key Takeaway

A $300K property in Sioux Falls with a $228K depreciable basis and 30% cost seg reclassification yields ~$25,308 in federal tax savings in Year 1. Because South Dakota has no state income tax, your total Year 1 savings = $25,308 with zero state tax friction.

Bottom Line

South Dakota is the simplest possible state for cost segregation planning. No state income tax = no state depreciation deductions = no conformity issues. Your entire savings are federal, immediate, and unreduced.
