Poshmark Fee Calculator

Poshmark's 20% headline rate is the highest of the big three resale platforms, but headline rates hide fee stacking. Here is the same $50 sale compared across marketplaces using each platform's July-2026 verified fees:

So why do closet resellers stay on Poshmark? The commission buys real things: buyer-paid shipping on every order (no label math, no shipping-fee base like Mercari's), zero listing or processing fees, Posh Protect handling disputes, and a fashion-focused buyer pool that supports higher sale prices for clothing and accessories. For a $200 designer bag, though, that $40 commission is real money — run your item through our Mercari and Etsy calculators before you choose where to list.

The tax question every Poshmark seller asks: is my closet cleanout taxable? Generally no — selling your own clothes for less than you paid creates no taxable income (and no deductible loss; the IRS treats personal-use property losses as nondeductible). But reselling for profit — thrifting, retail arbitrage, sourcing wholesale — is a business. Those profits go on Schedule C, and once net earnings hit $400, the 15.3% self-employment tax applies on top of income tax.

Poshmark issues Form 1099-K when gross sales exceed the federal threshold of $20,000 AND 200 transactions (restored by the One Big Beautiful Bill Act of 2025). Watch your state, though — Massachusetts, Maryland, Vermont, and Virginia require the form at just $600, and Illinois and New Jersey use $1,000 triggers. A 1099-K reports gross sales: your commissions, shipping discounts, item costs, and supplies all come off before anything is taxed. Since October 1, 2025, Texas-based sellers also have a Texas Seller Fee Tax deducted from earnings — keep those statements.

If your closet turned into a business, estimate your bill with the 1099 tax calculator and set aside the right amount each quarter with the quarterly tax calculator.
