Etsy, eBay, Shopify and the rest report your gross and withhold nothing. The gap between that and what you are taxed on is your costs, in Michigan that gap is worth $6,995 in tax.

A single filer taking the standard deduction, 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 | Michigan tax | Total tax | Rate on gross |
|---|---|---|---|---|---|---|
| Part-time | $15,000 | $0 | $15,000 | $592 | $2,712 | 18.1% |

Selling into and out of Michigan
Income tax follows you: Michigan taxes your profit wherever the buyer was. Sales tax does not. Marketplace facilitator laws make the platform collect and remit sales tax on your behalf in most states, which is why a seller can have customers in all fifty and still file only one income tax return. Selling off-platform is where that stops being true.

Marketplace seller tax questions in Michigan
How much should a Michigan seller set aside?
About 7.5% of gross on the $45,000 example, $3,362 across self-employment tax, federal income tax and $720 to Michigan. In practice that means moving about $75 of every $1,000 payout into a separate account the day it lands, and sending roughly $840 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 $45,000 on my 1099-NEC match what Michigan taxes?
No. Michigan taxes profit, not gross. After $26,775 of deductions the taxable figure is $18,225, so the Michigan bill is $720 rather than what gross alone would suggest. The form reports what the platform paid out, it knows nothing about your costs, and no one subtracts them for you. On this example 60% of the gross never becomes taxable income, but only for the seller who kept the records to prove it.
