Services and task work taxes in Illinois
TaskRabbit, Rover, Upwork and the rest report your gross and withhold nothing. The gap between that and what you are actually taxed on is mileage, in Illinois that gap is worth $2,363 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 Illinois and the IRS charge against.

Earning more in Illinois
A single filer taking the standard deduction, standard mileage method, this work as the only income, the calculator above handles the other filing statuses. Miles rise with earnings, so the deduction rises too, and the effective rate on gross climbs more slowly than it would for someone whose income grew without expenses attached:
| Volume | Gross | Mileage off | Taxable profit | Illinois tax | Total tax | Rate on gross |
|---|---|---|---|---|---|---|
| Part-time | $11,000 | $1,485 | $9,515 | $438 | $1,782 | 16.2% |
| Steady side income | $34,000 | $4,455 | $29,545 | $1,359 | $6,442 | 18.9% |
| Full-time | $55,000 | $7,425 | $47,575 | $2,189 | $11,362 | 20.7% |

Working across an Illinois 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.

About 15.4% of gross on the $34,000 example, $5,245 across self-employment tax, federal income tax and $1,149 to Illinois. Set aside from each payout rather than finding it in April.
Does the $34,000 on my 1099-NEC match what Illinois taxes?
No. Illinois taxes profit, not gross. After $9,030 of deductions the taxable figure is $24,970, so the Illinois bill is $1,149 rather than what gross alone would suggest.
