How your paycheck is taxed in South Dakota
South Dakota has no state income tax on wages, so the only taxes withheld from a South Dakota paycheck are federal. That means federal income tax (10% to 37% in 2026 after the $16,100 single or $32,200 joint standard deduction), Social Security at 6.2% of wages up to $184,500, and Medicare at 1.45% plus an extra 0.9% above $200,000. The state funds itself mainly through sales tax.
Formula
Net pay = Gross pay - Pre-tax deductions - Federal income tax - Social Security - Medicare - After-tax deductions. Federal taxable income is gross minus pre-tax deductions minus the standard deduction.

Worked examples: single filer, paid biweekly
Each row is a single filer with no pre-tax deductions, using the 2026 federal tables and the South Dakota rules above. The $75,000 example: federal taxable income is $58,900 after the $16,100 standard deduction, giving $7,670.00 of federal tax (10% on the first $12,400, 12% up to $50,400, 22% on the rest). Social Security is 6.2% of $75,000 = $4,650.00, Medicare is 1.45% = $1,087.50. Net pay is $61,592.50 a year, or $2,368.94 every two weeks.
| Salary | Federal tax | Social Security | Medicare | South Dakota tax | Net per year | Net per paycheck |
|---|---|---|---|---|---|---|
| $50,000 | $3,820 | $3,100 | $725 | $0 | $42,355 | $1,629.04 |
| $75,000 | $7,670 | $4,650 | $1,088 | $0 | $61,593 | $2,368.94 |
| $100,000 | $13,170 | $6,200 | $1,450 | $0 | $79,180 | $3,045.38 |
Effective total tax rates in these examples run from 15.3% at $50,000 to 20.8% at $100,000. Married filers with the same household income pay less federal tax because the joint standard deduction and brackets are twice as wide.
What no state income tax is worth
On the same $75,000 single salary, a California resident pays about $3,017 of state income tax and a New York resident about $3,520 (before New York City tax), while a South Dakota worker pays nothing. That is $116 to $135 more in every biweekly paycheck. South Dakota makes up the difference with other taxes, so the comparison is about paychecks, not total cost of living.
Hourly pay in South Dakota
Hourly workers are annualized the same way: rate x hours per week x 52. At $20 an hour for 40 hours, gross pay is $41,600 a year or $800 a week. Federal income tax is $54.08 a week, Social Security $49.60, Medicare $11.60, leaving $684.72 per weekly paycheck. Overtime raises the annualized figure and can push a few dollars into the next federal bracket, but only those dollars are taxed at the higher rate.
Married filing jointly on $75,000
A married couple filing jointly with $75,000 of combined wages gets the $32,200 joint standard deduction and brackets twice as wide, so federal income tax falls to $4,640.00 from $7,670.00 for a single filer. Social Security and Medicare do not change with filing status. Take-home pay for the couple is $64,622.50 a year, or $2,485.48 per biweekly paycheck.
