Understanding South Dakota Taxes
When calculating your total tax liability in South Dakota, it's important to consider all three major components of the US tax system:
1. Federal Income Tax
Federal income tax applies to all US taxpayers regardless of state. The federal tax system uses progressive tax brackets, meaning higher income levels are taxed at higher rates. For 2025, federal tax rates range from 10% to 37%.
2. South Dakota State Income Tax
South Dakota is one of the few states with no personal income tax. This can result in significant tax savings, especially for high-income earners. However, the state may generate revenue through other means such as sales taxes or property taxes.
3. FICA Taxes
FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare. These taxes are:
- Social Security Tax: 6.2% on income up to $168,600 (2025 limit)
- Medicare Tax: 1.45% on all income
- Additional Medicare Tax: 0.9% on income over $200,000 (single) or $250,000 (married filing jointly)
