2026 South Dakota tax snapshot
Rate, examples, and filing context
South Dakota does not levy a broad-based state income tax on wages in the current TaxGuide Pro calculator data. $60,000 single taxable income -> about $0 state income tax before credits. $120,000 married filing jointly taxable income -> about $0 state income tax before credits. These examples use taxable income before credits, local taxes, and residency allocation, so they are starting points rather than filed-return amounts.
Refine the estimate
Residency, local taxes, deductions, credits, and special income rules can change the result. Review dependent, household, income-based, and other South Dakota credits in the state credit finder, then confirm eligibility in official instructions. Full-year residents, part-year residents, and nonresidents may calculate state-source income differently, so use the residency option that matches the return you expect to file.
Verify before acting
For a 2026 return filed in 2027, confirm the due date in published South Dakota instructions. State deadlines and disaster relief can differ from federal dates. South Dakota does not guarantee one refund date for every return. E-filed, accurate returns with direct deposit are generally processed faster than paper or reviewed returns. Confirm forms, payment instructions, notices, and live refund status with the official agency rather than treating a planning date as a guarantee.

Build a complete South Dakota planning estimate
Start with income tax, then compare the result with paycheck withholding and any quarterly payments already made. Review capital gains, retirement distributions, Social Security, and unemployment separately when state treatment differs by income type. Finally, check deductions and credits before estimating a refund or balance due. This sequence keeps the same filing status, tax year, and residency assumptions across the tools and makes it easier to find why two estimates differ.
