How South Dakota is shown on the map
South Dakota is modeled with no state income-tax estimate on salary income, so the 2026 calculation is driven by federal income tax, Social Security, Medicare, and any pretax 401(k) contribution you enter.

What affects the estimate
The calculator starts with gross salary, subtracts the pretax 401(k) amount, estimates 2026federal taxable income, then allocates federal and state tax by the user's share of household income when married filing jointly.
Official source check
State deductions, credits, withholding forms, nonresident rules, and local taxes can change the final result. Use South Dakota Department of Revenue for the official South Dakota rules before making payroll or filing decisions.
Calculation context
What makes South Dakota different from other states?
In this app, South Dakota uses a 0% simplified state estimate rate. That rate changes the state tax line in the breakdown and the state's comparison rank when the full U.S. map is used.
The federal income tax, Social Security, Medicare, and 401(k) pieces stay the same when the same scenario is compared across states. The state tax estimate is the main modeled difference, so low-estimate and zero-estimate states generally show higher take-home pay for the same salary scenario.
On a state page, salary totals stay blank until a real user calculation exists. When you open this page after running a calculation, the detail panel reflects that salary scenario forSouth Dakota.
The calculator treats South Dakota salary income as a zero state income-tax estimate.
