Every reseller eventually discovers that their 1099-K is not their taxable income. That COGS matters. That platform fees are deductible. That the IRS treats a side hustle as a business. These tools handle all of that math — P&L, fee comparison, tax estimation, and inventory tracking — so tax season takes 30 minutes, not 7 hours.
Why This Suite Exists
“Built because Hayden spent 7 hours doing his eBay taxes. Nobody should have to do that.”
Hayden sold $23,000 on eBay part-time. eBay sent a 1099-K for $23,000. His accountant said he might owe tax on all of it. 7 hours of spreadsheet work later, the real number was $4,200 in profit and $641 in actual tax owed. The HBTax suite makes that calculation take 4 minutes.
Your 1099-K isn't your taxable income. Enter eBay gross sales, COGS, platform fees, and expenses — get your actual taxable profit, SE tax estimate, and the difference between what eBay reported and what you actually owe tax on.
Compare selling fees across eBay, Etsy, Poshmark, Depop, Facebook Marketplace, and Mercari. Enter sale price, shipping, and item cost — see net proceeds and profit on all 6 platforms side by side with the winner highlighted.
Multi-platform reseller tax calculator. Enter income per platform (eBay, Etsy, Poshmark, other), COGS, fees, filing status, and state — get taxable profit, SE tax, federal + state estimate, quarterly payment, and the set-aside percentage to save per sale.
Track what you paid for inventory, what you sold it for, and on which platform. Per-item COGS, platform fees, profit, margin, and days-to-sell. Export as CSV for your tax spreadsheet or CPA. Built so tax season takes 30 minutes, not 7 hours.
eBay, Etsy, Poshmark, and Amazon handle sales tax for you in most states. See which platforms are marketplace facilitators, your economic nexus exposure by state, and whether you need to register anywhere.

No. The 1099-K reports your gross sales — it is not your taxable income. You subtract your cost of goods sold (COGS), platform fees, shipping costs, and other business expenses to get your taxable profit. eBay has no idea what you paid for the items, so the 1099-K always overstates what you owe. Use the HBTax Reseller P&L Calculator to see the exact difference between what eBay reported and what you actually owe tax on.
Yes — eBay, Etsy, Poshmark, Amazon, Mercari, and most major platforms are marketplace facilitators. They collect and remit sales tax on your behalf in all states that require it. You generally do not need to register for a sales tax permit in those states. The exception: if you also sell off-platform (your own website, in-person), you may have nexus obligations in certain states. Use the HBTax Reseller Sales Tax Guide to check your exposure by state.
For 2024, the threshold is $5,000 in gross payments. If your total sales through any single platform exceed $5,000, that platform must send you (and the IRS) a 1099-K. You must report all taxable income even if you do not receive a form — the threshold only determines when the platform is required to report, not when you owe tax.
It depends on what you are selling and at what price. eBay Final Value Fees range from 6.35% to 15% depending on category. Etsy charges a 6.5% transaction fee plus listing fees. Poshmark takes a flat 20% on sales over $15. Depop charges 10%. Use the HBTax Platform Fee Calculator to enter your actual sale price and see net proceeds across all 6 platforms side by side — ranked by payout.
It depends on whether reselling is a business or a hobby. If you sell casually (occasional personal items), sales are generally not subject to SE tax. If you buy items specifically to resell — even part-time — the IRS considers it a Schedule C business, and net profit above $400 is subject to self-employment tax (15.3%). Use the HBTax Reseller Tax Estimator to calculate your SE tax, federal income tax, and quarterly payment amount.
