No state income tax - Mount Rushmore State relies on sales/tourism taxes
South Dakota has no state income tax, constitutionally prohibited since statehood in 1889. At $100,000 income, residents pay only $12,908 federal tax with zero state tax burden. South Dakota ranks among 9 US states with no income tax, making it one of the most tax-friendly for workers, retirees, and business owners seeking to maximize take-home pay while enjoying low cost of living and business-friendly environment.
South Dakota has no state income tax, a policy constitutionally protected since statehood in 1889. Any attempt to introduce an income tax would require amending the South Dakota Constitution via statewide referendum, making it highly unlikely to change. This makes SD one of the most tax-friendly states for individuals and businesses.
Why no income tax? South Dakota relies on other revenue sources including sales tax (4.5% state + up to 2% local), property tax (1.12% average), tourism revenue ($4.1B annually from Mount Rushmore, Badlands National Park, Sturgis Motorcycle Rally), and bank franchise taxes (SD is a credit card/trust haven with 50+ financial institutions headquartered here, generating $112M annually). This "South Dakota Model" attracts businesses, retirees, and remote workers fleeing high-tax states.
How it compares:
Recent changes: In 2023, South Dakota voters rejected Initiated Measure 28 which would have eliminated sales tax on groceries (maintaining 4.5% sales tax on food to fund state budget). The state continues to prioritize fiscal conservatism: lowest state debt per capita nationally ($4,071 vs $5,788 national average), balanced budget requirement, and AAA credit rating.
The tradeoff - Sales tax + property tax replace income tax: South Dakota generates $2.2B revenue (2026) without income tax: $1.4B sales tax (4.5% + local), $450M property tax (1.12% average), $112M bank franchise, $250M tourism-related. At $100K income + $40K annual spending: SD pays $0 income + $1,800 sales (4.5% × $40K) + $3,360 property (1.12% × $300K median home) = $5,160 total (5.2% burden). California (9.3% income + 7.25% sales + 0.74% property): $5,762 income + $2,900 sales + $2,220 property = $10,882 total (10.9% burden on $100K). Result: SD saves $5,722/year vs CA, nearly 50% less total tax burden.
The California/Minnesota question - Sioux Falls as 'insurance/banking capital': South Dakota's 0% income tax attracts businesses and high earners from high-tax states. Sioux Falls (population 213K, largest SD city) is a major credit card processing center (Citibank, Wells Fargo, Capital One) and insurance hub (Poets&Quants, Sanford Health). At $120K salary: MN tax $7,140 (5.95% effective) vs SD $0 = save $7,140/year. Add: Sioux Falls housing $315K vs Minneapolis $425K (save $110K), SD no corporate income tax (vs MN 9.8%), lower cost of living (groceries 10% cheaper). Trade-offs: Sioux Falls feels small (213K metro vs 3.7M Minneapolis), harsh winters (-5°F January average, blizzards), limited urban amenities, brain drain (young people leave for larger cities).

Tax considerations if moving here:
| State | Tax Rate | Tax on $100K Income | Difference from South Dakota |
|---|---|---|---|
| South Dakota | 0% | $0 | Baseline |
| North Dakota | 1.95-2.5% | $2,375 | +$2,375 (more tax) |
| Minnesota | 5.35-9.85% | $7,140 | +$7,140 (more tax) |
| Iowa | 4.4-5.7% | $4,850 | +$4,850 (more tax) |
| Wyoming | 0% | $0 | $0 (same) |
Key insight: South Dakota's 0% income tax saves residents $2,375-7,140/year at $100K income compared to neighboring states with income tax. Compared to Minnesota, savings are $7,140/year at $100K, $12,315/year at $150K, and over $22,500/year at $250K. Wyoming also has 0% income tax (ties SD).
But consider total tax burden (income + sales + property):
Result: South Dakota's 5.3% total burden is lower than Minnesota (13.4%) and North Dakota (7%), but higher than Wyoming (3.6%) due to WY's ultra-low 0.6% property tax. SD is middle-tier among 0% income tax states - wins for high earners prioritizing income tax savings, loses slightly to WY for homeowners prioritizing property tax.
No, South Dakota has no state income tax. This policy is constitutionally protected since statehood in 1889 - any future income tax would require amending the South Dakota Constitution via statewide referendum (highly unlikely given conservative political culture). Residents pay only federal income tax (10-37% based on income). South Dakota is one of only 9 US states with no income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming).
South Dakota generates $2.2B revenue (2026) through sales tax (4.5% state + up to 2% local = $1.4B, 64% of revenue), property tax (1.12% average = $450M, 20%), tourism ($4.1B economic impact from Mount Rushmore, Badlands, Sturgis Rally, Deadwood casinos = $250M tax revenue), bank franchise taxes ($112M from 50+ credit card/trust companies headquartered here, SD is a financial services haven), and federal transfers. This diversified model funds $6.2B state budget (2026): $2.1B K-12 education, $1.8B Medicaid, $850M higher education, $450M transportation. Result: SD maintains AAA credit rating + lowest state debt/capita nationally ($4,071) without income tax.
At $100K income: save $7,140/year vs Minnesota (MN 7.14% effective rate vs SD 0%). At $150K: save $12,315/year vs MN. At $250K: save $22,500/year vs MN. Compared to California: at $100K save $5,762/year (CA 5.76% effective), at $150K save $10,991/year, at $250K save $22,471/year. Over 30-year career earning $150K average: SD saves $369,450 vs MN, $329,730 vs CA (enough to buy a Sioux Falls home cash). Trade-offs: Sioux Falls housing $315K vs Minneapolis $425K (save $110K upfront), but harsh winters (-5°F January) and limited urban amenities (Sioux Falls 213K vs Minneapolis 3.7M metro).
South Dakota repealed usury laws in 1981 (no cap on credit card interest rates) + offers favorable trust laws (dynasty trusts perpetual, no state income tax on trust income, privacy protections), attracting Citibank (1981, moved credit card operations from NY to SD), Wells Fargo, Capital One, and 50+ financial institutions. This generates $112M annual bank franchise tax revenue (taxed on assets held, not income) + 15K high-paying jobs (Sioux Falls median income $68K, 10% above national $62K). SD offers: no corporate income tax, no personal income tax on dividends/capital gains, favorable business climate (ranked #2 Forbes). Result: $1.6T+ assets held in SD trusts, billionaires use SD dynasty trusts (Rockefeller family, others) to avoid state income/estate taxes.
Yes, South Dakota charges 4.5% state sales tax on groceries (+ up to 2% local = 6.5% in Sioux Falls). This is REGRESSIVE (low-income families spend 30% of income on food vs 10% for high earners). In 2023, voters rejected Initiated Measure 28 (62% NO, 38% YES) which would have eliminated grocery sales tax, due to: (1) Revenue concerns - eliminating grocery tax would cost $120M annually (5.5% of state budget), requiring cuts to education/Medicaid or replacing with income tax (unacceptable to conservative voters), (2) Measure wording - also eliminated sales tax on 'items consumed by humans' (medicine, clothing?), creating confusion about scope, (3) Conservative opposition - Governor Noem + business groups argued SD's low-tax model works, don't create budget hole. Result: SD continues taxing groceries at 4.5%, regressive but necessary to maintain 0% income tax model without cutting services.
Yes, IF you prioritize ultra-low taxes + cost of living over urban amenities and warm climate. At $120K remote salary: SD $0 tax + $1,890 sales (6.5% Sioux Falls × $29K spending) + $3,528 property (1.12% × $315K home) = $5,418 total (4.5% burden). CA $7,800 tax + $2,103 sales (7.25% × $29K) + $2,331 property (0.74% × $315K) = $12,234 total (10.2%). SD saves $6,816/year + $315K Sioux Falls home vs $800K+ coastal = save $485K upfront. Over 10 years: save $68,160 taxes + $485K housing = $553,160 total savings. Trade-offs: Sioux Falls feels VERY small (213K vs SF Bay 7.7M, limited restaurants/culture/diversity), harsh winters (-5°F January, blizzards, snow Oct-April), isolation (4hrs Minneapolis, 6hrs Denver, regional airport), conservative culture (SD 62% voted Trump 2024). WINS for: tax minimizers (save $553K+ over 10 years), families prioritizing safety (4th-lowest crime nationally), fiscal conservatives (AAA-rated state, balanced budget). LOSES for: urban lifestyle lovers (SF/NYC/Austin culture > Sioux Falls prairie town), warm-weather seekers (SD winter brutal), career climbers (limited networking/job hopping in small market).
