What is the South Dakota Income Tax Calculator?
In short
South Dakota charges no state individual income tax. A single filer earning $75,000 keeps about $61,593 after federal income tax and employee FICA under the 2026 standard deduction. Spending is separate: the state sales and use tax is 4.2%, with possible municipal additions. Benefits and other omitted taxes can change your actual paycheck.
This South Dakota income tax calculator estimates federal income tax and employee FICA on wages, with a zero state individual income-tax line. Its state-specific notes distinguish other taxes from this wage estimate. South Dakota collects a 4.2% state sales and use tax on taxable products and services, including electronically delivered products. Municipalities may add a general sales tax up to 2%; certain lodging and amusement services also carry tourism tax.

Worked example
The scenario
A South Dakota worker earning $75,000, filing single with the standard deduction and no elective deductions, compares a $10,000 taxable purchase basket with Wyoming. A second scenario assumes a South Dakota municipality levies the full 2% general sales tax.
The result
Wage take-home is about $61,593 after federal tax and employee FICA; the South Dakota individual income-tax line is zero. On the same hypothetical taxable basket, South Dakota's 4.2% state sales tax is $420 and Wyoming's mandatory 4% state portion is $400. The state-only difference is $20. Where the assumed 2% municipal general sales tax applies, add $200 to the South Dakota basket, making $620 in general sales tax. Wyoming's voter-approved local additions are outside this comparison, as are exemptions, special taxes and purchases that are not taxable in both places. The calculation isolates consumption taxes rather than proving that one state is cheaper overall. A bank account, a hotel stay and a wage paycheck can involve different tax rules; none is fully described by the zero state income-tax line. Use the actual municipality and purchase category for a spending budget, then compare that cost with the wage result instead of subtracting a statewide average from every paycheck.
Common use cases
- Separating the South Dakota wage estimate from taxes on purchases and businesses
- use tax can apply to products and services consumed in South Dakota when sales tax has not been paid
- the tourism tax is 1.5% on covered receipts; lodging is taxed year round, while visitor-intensive businesses are covered during June through September
- Separating a South Dakota wage estimate from a financial institution's bank franchise filing requirements
Limitations & assumptions
- The wage estimate excludes elected benefits, federal credits and Additional Medicare Tax at higher incomes. It is an annual wage estimate, not a payroll withholding or business-tax calculation.
- South Dakota has no state income tax, so this shows federal + FICA only. South Dakota does not impose a corporate income tax, but financial institutions regularly engaged in business in the state must file a bank franchise tax return. The wage calculator does not calculate those business taxes.
- A bank franchise tax return is required for financial institutions regularly doing business in South Dakota, despite the absence of corporate income tax.
- Federal tax uses current brackets and the standard deduction unless you itemize.
- This is an estimate, not tax advice — verify against your actual return.
