About these South Dakota figures: state tax here is calculated from a compiled 2025/2026 rate table using each jurisdiction's brackets and standard deduction — not from South Dakota's own published schedule, and not every entry has been confirmed against it. Treat the result as an estimate and check anything you are relying on with South Dakota's revenue department. Federal figures come from published IRS releases and are cited on the pages that use them. See how we calculate and what has been verified.
What Is a 1099 Tax in South Dakota?
No employer withholds tax from a 1099-NEC, so a South Dakota contractor settles the whole bill themselves. Worked through on $75,000 of net freelance income, the two pieces come out like this:
- Self-employment tax — $10,597: 15.3% covering Social Security and Medicare, charged on 92.35% of net earnings. Federal, so it is the same in South Dakota as anywhere else.
- Federal income tax — $4,898: what remains after deducting half your self-employment tax and the $16,100 standard deduction, then running the 2026 brackets.
That totals $15,495, an effective rate of 20.7%, leaving $59,505 — and because South Dakota takes no income tax, every dollar of that difference against a taxed state stays with you.

1099 Tax FAQ — South Dakota
How much should I set aside for 1099 taxes in South Dakota?
Plan on roughly 20.7% of every payment. South Dakota charges no state income tax, so the whole bill is federal: on $75,000 that is $10,597 of self-employment tax plus $4,898 of federal income tax, or $3,874 per quarter. In Minnesota (top rate 9.85%) the same income would cost another $3,216 a year in state tax, which is what crossing that border is worth.
What is the South Dakota state tax rate on freelance income in 2026?
