South Dakota tools

2026 South Dakota tax snapshot
South Dakota does not levy a broad-based state income tax on wages in the current TaxGuide Pro calculator data. The examples below use taxable income before credits, local taxes, or part-year allocation, so they are planning estimates rather than filed-return amounts.
Sales tax
The midyear 2026 benchmark combines a 4.2% state rate and a 1.91% population-weighted local average. Exact local and product rates can differ.
Real-estate tax
The 2026 Census-based statewide estimate is a comparison measure. Local assessed value, millage, exemptions, and special districts determine an actual property-tax bill.
Start with the South Dakota income tax calculator and use state taxable income, not gross pay, when the form asks for a taxable-income figure. Filing status, residency, deductions, exemptions, and credits can all change the final result. A part-year resident or nonresident should allocate only the income connected to South Dakotaunder the state's sourcing rules.
Next, compare the estimate with withholding and estimated payments. A projected refund means payments may exceed estimated tax; a projected balance means the current payment pattern may be short. Neither result is final until income, adjustments, deductions, credits, and payments are reconciled on the official South Dakota return.
Use the retirement, Social Security, unemployment, and capital-gains tools for income types that may receive different state treatment. The property-tax and SALT tools answer federal itemized-deduction questions; they do not calculate a county property-tax bill or replace local assessment records.
Tax rules can change after planning figures are published. Check the visible update date on each calculator and verify the result with current agency instructions, especially before filing, responding to a notice, or making a payment. Refund estimates should be paired with the agency's live status tool because identity review, missing information, and filing method affect timing.
Use these primary sources to confirm current rates, forms, due dates, payment instructions, and refund status before taking action.
South Dakota has no broad-based state tax on wages, so income-tax tools should show $0 and point you to the other taxes that still matter.
