PayoutTaxTopstep payout taxes in Illinois
Updated November 8, 2026 · For the 2026 tax year
A Topstep payout has no tax withheld, federal or Illinois. On top of federal income tax and self-employment tax, Illinois taxes it at a flat 4.95%. For a single filer with a $70,000 day job, a $5,000 payout needs $1,958.78 set aside.
PayoutTax isn't affiliated with Topstep. The Topstep details below come from its help pages, as summarized in the Topstep tax guide; the Illinois figures come from the PayoutTax 2026 tax tables, each linked to the state source.
How Topstep reports your payouts
Topstep emails a Form 1099-NEC to US citizens. It sent the 2025 forms on January 31, 2026, to US citizens with over $600 in payouts, and says to check your spam folder if yours doesn't show up. Questions about the form go to 1099support@topstep.com. For payments made in 2026 the IRS threshold is generally $2,000, and Topstep's page doesn't say which line it will use for 2026 payouts. Either way, a payout with no form is still Illinois income.
Topstep collects a W-9 from US citizens, and a US single-member LLC can receive payouts (C-corps, S-corps and multi-member LLCs can't). The form shows your gross payout, before processing fees.
How Illinois taxes a payout
Illinois taxes income at a flat 4.95% (2026 Booklet IL-700-T). There's no standard deduction; the exemption is $2,925 per person, and it's lost once federal AGI passes $250,000 for a single filer (Illinois exemption answer). Illinois starts from federal AGI, so the deductible half of self-employment tax lowers it.
A day job usually uses up the exemption already, so the payout is taxed at the full rate after that half of self-employment tax comes off. The Illinois guide covers the state's estimated payment rules.
How much to set aside in Illinois
Single filer, $70,000 of W-2 wages, no trading costs, one payout in 2026. These are the calculator's numbers.
| Payout | Illinois tax | Set aside | Share |
|---|---|---|---|
| $1,000 | $46.00 | $391.76 | 39.18% |
| $5,000 | $230.01 | $1,958.78 | 39.18% |
| $10,000 | $460.03 | $3,917.56 | 39.18% |
| $25,000 | $1,150.07 | $9,793.90 | 39.18% |
| $50,000 | $2,300.15 | $19,587.80 | 39.18% |
At this wage every payout here, from $1,000 to $50,000, comes out at the same share.
A $5,000 payout, line by line
| Tax on the payout | Illinois | Texas |
|---|---|---|
| Federal income tax | $1,022.29 | $1,022.29 |
| Self-employment tax | $706.48 | $706.48 |
| State income tax | $230.01 | $0.00 |
| Set aside | $1,958.78 | $1,728.76 |
| Share of the payout | 39.18% | 34.58% |
The lines can differ from the total by a cent, because the calculator rounds only at the end. The same payout in Texas is shown for comparison.
Topstep's $500 example in Illinois
Topstep's help page uses a $500 payout request with a $30 processing fee: the 1099-NEC shows $500 and you receive $470. Topstep says to deduct the $30 as a business expense on Schedule C. For a single filer in Illinois with a $70,000 day job, the calculator puts the set-aside at $184.13 once the fee is counted, against $195.88 if you forgot it. Payouts through Wise have no processing fee, so the form and your deposit match.
If Topstep is your only income
With no day job, the deductions that a wage would use up come off your payouts instead, including Illinois's $2,925. On $60,000 of payouts, Illinois tax is $2,615.39 and the whole set-aside is $15,604.45, or 26.01%.
Paying it during the year
The 1099-NEC arrives after the year ends, but the tax is due during the year. The next federal estimated payment is due January 15, 2027 (the January payment guide explains it), and payouts go on Schedule C and Schedule SE when you file. Illinois estimated payments have their own rules; PayoutTax's quarterly amounts cover federal tax only.
What the estimate leaves out for Illinois:
- City, county or school-district income taxes are not included.
- Does not include the qualified business income (QBI) deduction, credits, other income or itemized deductions. You may qualify for the QBI deduction, which would lower the federal tax; ask your CPA.
