State Gig Tax Guide
South Dakota Gig Worker Taxes: The Complete Breakdown
If you drive, deliver, or freelance in South Dakota, platforms pay you as an independent contractor and withhold nothing. The good news: South Dakota has no personal state income tax. The catch: your federal obligations — income tax plus the 15.3% self-employment tax — apply in full. Here's how it works.
← Part of the complete Gig Worker Taxes guideHow gig taxes work for South Dakota workers
You're an independent contractor — nothing is withheld
Gig platforms pay you as a 1099 contractor, not an employee, so no income or payroll tax comes out of your payouts. You're responsible for setting aside and paying your own taxes.
Federal self-employment tax is 15.3%
That's 12.4% Social Security + 2.9% Medicare on your net earnings — the employer-plus-employee share that a regular job would split with you. It applies in every state, on top of federal income tax.
Federal income tax applies to your net profit
After deductions, your net gig profit is added to your other income and taxed at your federal rate. You can deduct half of your self-employment tax when figuring federal income tax.
Report all income — even without a 1099
You must report every dollar you earn whether or not a platform sends a 1099-NEC or 1099-K. Reporting thresholds for the forms change year to year; your obligation to report does not.
Does South Dakota have a state income tax for gig workers?
No. South Dakota does not levy a personal state income tax, so you won't file a state income-tax return on your gig earnings and there are no state income-tax estimates to make.
Your gig income is not tax-free, though. The federal rules are the same in every state: federal income tax on your net profit plus the 15.3% federal self-employment tax (12.4% Social Security + 2.9% Medicare), with nothing withheld from your payouts.
Because there's no state income tax to pay, you only send federal estimated payments to the IRS — but you should still make those quarterly if you expect to owe $1,000 or more for the year.
Remember: no South Dakota income tax does not mean no taxes — the 15.3% federal self-employment tax and federal income tax still apply in full.
What South Dakota gig workers can deduct
Business mileage
Every mile driven while online or on a job, deducted at the IRS standard mileage rate. Usually the single largest deduction — keep a contemporaneous log.
Phone & data
The business-use percentage of your phone and data plan — you cannot accept jobs without it.
Supplies & equipment
Insulated bags, phone mounts, chargers, and other gear bought specifically for the work.
Tolls & parking
Tolls and parking paid while working are deductible (ordinary commuting tolls are not).
You can deduct the IRS standard mileage rate or your actual vehicle expenses — not both. For most drivers the standard mileage rate is simpler and larger. Keep a contemporaneous mileage log either way.
Quarterly estimated taxes
Because no tax is withheld from your payouts, the IRS expects you to pay as you go through quarterly estimated payments rather than one lump sum in April. If you expect to owe $1,000 or more in federal tax for the year, paying quarterly avoids an underpayment penalty.
Federal estimated payments are generally due around April 15, June 15, September 15, and January 15 of the following year. You file your annual federal return by April 15. South Dakota has no personal income tax, so there are no separate state estimated payments to make.
Frequently asked questions
Do South Dakota gig workers pay state income tax?
No. South Dakota has no personal state income tax, so your gig earnings aren't subject to state income tax and there are no state estimated payments. You still owe federal income tax and the 15.3% federal self-employment tax.
How much should I set aside for taxes in South Dakota?
A common rule of thumb is to set aside roughly 20–25% of your net earnings (what's left after mileage and other deductions) to cover the 15.3% self-employment tax plus federal income tax. With no state income tax to add, your set-aside is often a little lower than in states that tax income — but your exact rate depends on your total household income. Use the Tax Set-Aside calculator for a number tailored to your situation.
Is gig income tax-free in South Dakota?
No. While South Dakota charges no state income tax, your federal obligations apply in full: federal income tax on your net profit plus the 15.3% self-employment tax. Report all income whether or not a platform sends a 1099.
Do South Dakota gig workers pay quarterly taxes?
Yes — federal quarterly estimated payments. If you expect to owe $1,000 or more in federal tax for the year, the IRS generally expects payments around April 15, June 15, September 15, and January 15. There are no South Dakota state estimates to make.
