Cost of goods is the deduction resellers miss

The single biggest write-off for a Poshmark reseller is the cost of goods sold: what you paid to acquire the items you sold this year. If you bought a jacket for $20 and sold it for $60, you are taxed on the profit, not the $60. Enter your total cost of goods in the expenses field above, and the calculator subtracts it along with Poshmark’s 20% fee before working out the tax. One nuance worth knowing: cost of goods counts only for items you actually sold, so unsold inventory sitting in your closet is not deductible yet.

Reselling for profit vs. cleaning out your closet

The tax treatment splits on intent. Selling your own used clothes for less than you paid is not taxable, and you cannot deduct the loss, though you still report and back out a 1099-K if you get one. Buying inventory to flip for profit is a business: the net profit goes on Schedule C and is subject to self-employment tax once it reaches $400. This calculator is built for that for-profit case. Since 2025 the federal 1099-K threshold is back to more than $20,000 and 200 transactions, but many states report at far lower amounts, so do not treat a missing form as proof you owe nothing.

Because nothing is withheld, run your numbers through the quarterly estimated tax calculator so the April bill never surprises you, and read our Poshmark and Mercari tax guide for the full Schedule C walkthrough.

These are estimates, not tax advice. State income tax is included when you select a state (2026 single-filer brackets, excluding state standard deductions and local taxes). Unusual situations belong with a CPA.

Where these numbers come from

Take-home is computed as gross sales minus Poshmark's fee and your cost of goods, then minus self-employment tax, federal income tax, and state income tax where selected. The rates come from these primary sources:

Constants last verified against these sources on June 18, 2026. Every value is also pinned by an automated test suite that fails if a rate in the calculator drifts from the figure we transcribed from the source.

Frequently asked questions

What fees does Poshmark take from a sale?
Poshmark keeps 20% of each sale of $15 or more, and a flat $2.95 on anything under $15. That commission is all-inclusive and also covers the prepaid USPS shipping label. This calculator applies the 20% rate, which is accurate for any sale that matters for tax; very small sales pay a slightly higher effective rate because of the $2.95 floor.
What can I deduct as a Poshmark seller?
If you buy items to resell for profit, your largest deduction is the cost of goods sold, meaning what you paid for the items you actually sold during the year. Packaging and shipping supplies are deductible too. Poshmark's selling fee is also a business expense, and this calculator already subtracts it as the platform fee. Enter your cost of goods in the expenses field above.
What tax form does Poshmark send, and at what threshold?
Poshmark issues Form 1099-K. For 2025 and later the federal reporting threshold is more than $20,000 in gross sales and more than 200 transactions, after the One Big Beautiful Bill Act restored the pre-2021 figures. Several states set lower thresholds, so you may receive one well below $20,000. Sales tax that Poshmark collects and remits for you is not part of your taxable sales.
I'm just selling my old clothes at a loss. Do I owe tax?
Generally no. Selling used personal items for less than you originally paid is not taxable income, and the loss is not deductible. If you receive a 1099-K for those sales, you still report the amount and then back it out so the taxable total is zero. This calculator is built for the other case: buying inventory to resell at a profit, which is business income on Schedule C and subject to self-employment tax.
Is Poshmark income subject to self-employment tax?
If you are reselling for profit as an ongoing activity, yes. Net profit on Schedule C is subject to the 15.3% self-employment tax once it reaches $400 for the year, on top of federal income tax. A one-time closet cleanout at a loss is not a business and does not trigger SE tax. The calculator above assumes the for-profit reseller case.
Do I have to pay quarterly estimated taxes?
If you expect to owe $1,000 or more in federal tax for the year, yes. The 2026 due dates are April 15, June 15, and September 15, 2026, then January 15, 2027. This calculator shows a suggested per-quarter payment based on your numbers.
