Services and task work taxes in South Dakota
TaskRabbit, Rover, Upwork and the rest report your gross and withhold nothing. The gap between that and what you are taxed on is mileage, in South Dakota that gap is worth $1,947 in tax.
Take a driver who grossed $34,000 over 18,000 business miles. After mileage at 74.3 cents and the rest of the stack, worked through on the services and task work page $9,030 comes off and $24,970 is left as taxable profit. That profit is what South Dakota and the IRS charge against.

Earning more in South Dakota
A single filer taking the standard deduction, standard mileage method, this work as the only income, the calculator above handles the other filing statuses.

South Dakota specifics that change the number
South Dakota pairs its missing income tax with one of the lowest state sales tax rates, 4.2%, and no broad business income tax on top. A business with physical presence in the state needs a sales tax license from the first sale; remote sellers only after $100,000 of sales into the state.
Working across a South Dakota line
Services income is sourced to where the work was physically done. A job over the line can create a filing obligation in that state even for a single afternoon, and reciprocity agreements do not help, they cover wages paid by an employer, not self-employment income.

Services and task work tax questions in South Dakota
How much should a South Dakota contractor set aside?
About 12.0% of gross on the $34,000 example, $4,097 across self-employment tax, federal income tax and nothing to South Dakota. In practice that means moving about $120 of every $1,000 payout into a separate account the day it lands, and sending roughly $1,024 to the IRS each quarter, no platform withholds any of this for you. Set aside from each payout rather than finding it in April.
Does the $34,000 on my 1099-NEC match what South Dakota taxes?
No. South Dakota taxes profit, not gross. After $9,030 of deductions the taxable figure is $24,970, so there is no South Dakota tax either way. But the federal side drops by $1,947. The form reports what the platform paid out, it knows nothing about your costs, and no one subtracts them for you. On this example 27% of the gross never becomes taxable income, but only for the contractor who kept the records to prove it.
