Short-Term Rental Taxes in South Dakota: No Income Tax, Black Hills, and Cost Seg Benefits
NO state income tax | Full federal bonus depreciation benefit — no state offset | 4.5% state sales tax + local taxes (~9% total in most markets) | Top markets: Black Hills (Rapid City, Deadwood, Mount Rushmore area), Custer State Park, Sturgis area | Excellent tax environment for STR investing
South Dakota joins a small group of states — including Florida, Texas, Nevada, and Wyoming — with no state personal income tax, giving it an exceptional tax environment for STR investors. The Black Hills region in western South Dakota is a legitimate national tourism destination: Mount Rushmore, Crazy Horse Memorial, Custer State Park, Badlands National Park, and the historic gambling town of Deadwood draw millions of visitors annually. The annual Sturgis Motorcycle Rally creates one of the single largest concentrated STR demand events anywhere in the Midwest.
No South Dakota Income Tax: A Major STR Advantage
South Dakota's constitutional prohibition on income taxes is one of the most investor-friendly tax policies in the country. For STR investors, this means: (1) 100% of net rental income is only subject to federal taxes; (2) Cost segregation deductions flow entirely to the federal return with no state-level complexity; (3) The STR loophole produces federal loss deductions with no state offset required; (4) There is no South Dakota individual income tax return to file.
Compare this to neighboring states: Minnesota charges up to 9.85% and doesn't conform to bonus depreciation. North Dakota charges 2.9% (low, but still present). Iowa is trending to 3.9%. South Dakota investors simply pay federal taxes — and keep the full federal benefit of every dollar of cost segregation deductions.

The Black Hills: South Dakota's STR Powerhouse
- Mount Rushmore / Keystone: 2–3 million annual visitors; family-oriented; strong summer demand; July 4th is one of the most intense demand days in the entire Midwest for STR properties
- Deadwood: Historic gold rush town with legalized gambling; adult-oriented; year-round demand from casino visitors; unique regulated environment with specific STR rules
- Custer State Park: 71,000 acres of spectacular Black Hills scenery; free-roaming bison herds; game drives and wildlife viewing; very limited lodging supply relative to demand — cabin rentals near the park command premium rates
- Sturgis Motorcycle Rally: 700,000+ attendees each August; creates the single most intense 10-day STR demand event in the entire Midwest; properties within 30 miles of Sturgis can generate months of revenue in one Rally week
- Badlands National Park: 1M+ annual visitors; limited nearby lodging; Wall Drug tourism complex on the eastern approach; STR demand is strong in the Rapid City-to-Wall corridor
Sturgis Rally: The Annual Revenue Windfall
The Sturgis Motorcycle Rally in early August deserves special mention. Properties within 30–50 miles of Sturgis — including Rapid City, Deadwood, and throughout the Black Hills — see nightly rates increase 5–10x during the Rally's 10-day run. A property that normally rents for $200/night can command $800–$2,000/night during Sturgis. This annual revenue spike is a unique financial advantage of Black Hills STR ownership that investors should factor heavily into purchase economics.
Cost Segregation in South Dakota
South Dakota's no-income-tax environment makes cost segregation maximally effective. Every dollar of federal deduction benefits the investor at their full federal rate (37% for high-income investors) with zero state offset. Black Hills cabin properties have good cost segregation profiles — rustic amenities (fireplaces, decks, hot tubs, outdoor seating areas), pine log construction details, and vacation furnishing packages contribute to personal property ratios of 20–30%. A $500,000 Black Hills cabin with $125,000 in bonus-eligible deductions generates $46,250 in first-year federal tax savings — with no South Dakota state income tax on rental income to worry about.
