Gig driver taxes in South Dakota (2026)
South Dakota has no state income tax on your driving income, so what you set aside is federal only: self-employment tax and federal income tax. Here is what that comes to for a typical driver, computed by the same engine RoadKept runs on your own records.
A worked example for South Dakota
A driver in South Dakota expects $52,000 gross, drives 28,000 business miles split evenly across the two 72.5¢ and 76¢ periods, has $1,800 of other deductible costs, and files single.
Mileage takes $20,790 off, leaving $29,410 of profit. Self-employment tax is $4,156, federal income tax $899 after QBI and the half-SE deduction. South Dakota takes nothing, so the state line is $0.
That is $5,054 for the year — about 10% of every payout. Spread across the four estimated-payment dates, that is $1,264 a quarter, all of it federal.
RoadKept keeps this number current from your real miles and payouts, in South Dakota's rules, and warns you before each deadline.
South Dakota 2026 estimated-payment dates
South Dakota has no state estimated payments. The federal dates are the only ones that apply:
| Period | Due | Share of the year |
|---|---|---|
| Q1 | April 15, 2026 | 25% |
| Q2 | June 15, 2026 | 25% |
| Q3 | September 15, 2026 | 25% |
| Q4 | January 15, 2027 | 25% |
If a date falls on a weekend or holiday it moves to the next business day. Q2 covers two months, not three, and Q4 is not due until the following January.
What this page does not do
- RoadKept figures one state — where you live. If you drove for work in more than one state, the split between them is a question for your preparer; this won't guess at it.
- No standard deduction is modelled, which overstates federal income tax; the Social Security wage base is applied, but this page does not ask for W-2 wages. On a set-aside figure, too high is the safe direction to be wrong.
- This is a planning estimate, not the figure you file.
Questions drivers in South Dakota ask
Does South Dakota tax gig driving income?
No. South Dakota has no individual income tax on earned income, so a 1099 driver in South Dakota owes federal self-employment tax and federal income tax and nothing to the state. Your set-aside is the federal figure alone.
How much should a 1099 driver in South Dakota set aside?
For the worked example — $52,000 gross, 28,000 business miles split across the two 2026 rates, $1,800 of other costs, filing single — the year's total is $5,054, which is about 10% of every payout. Your own figure depends on your miles and your income; RoadKept computes it from your records.

Does RoadKept compute South Dakota state tax?
RoadKept knows South Dakota takes nothing, so it states your set-aside as the federal figure and says so, rather than leaving a blank. It figures one state — where you live; if you drove for work in more than one state, the split is a question for your preparer.
