Whatnot taxes for sellers, the basics
What gets taxed when you sell on Whatnot, why net profit is the number that matters, and the records that make tax time painless.
Do Whatnot sellers pay taxes?
Generally yes: if you sell for profit, the profit is income, and income is what tax systems tax. The useful question is not whether but on what, and the answer in almost every country is the same: your net profit, not your gross sales and not your payouts. That distinction is the whole article.
One note before the detail: BreakCount keeps records; it does not give tax advice. The rules differ by country, by state and by how you sell, so for your own situation, talk to a professional. What never differs is that good records make their job cheaper and yours calmer.
What gets taxed when you sell on Whatnot?
Net profit is what remains of gross after the selling costs come out: the commission and payment processing fees on every sale, the shipping you paid, the giveaways you ran, what your inventory cost you, and the other costs of running the operation. Sell $2,000 of cards from a case that cost $1,400 and you did not earn $2,000; after fees, postage and the case, the number that matters might be a few hundred dollars.
This cuts both ways. Without records, some sellers overstate their income by reporting something close to gross, and others understate it by guessing. Both problems have the same cure: knowing your real net profit per show and per year.
Which of those costs are commonly deductible, beyond the platform fees, is covered family by family in Whatnot seller tax deductions.
The US part: forms and the first dollar
For US sellers, two facts sit at the center. First, taxable income is taxable from the first dollar; whether any form arrives changes nothing about what you owe. Second, the form that may arrive is the 1099-K, and it reports your gross, never your profit, which is why sellers who rely on it alone tend to overstate their income. We cover the current threshold and the details in does Whatnot send tax forms.
The selling costs themselves are the other half of the US picture: platform fees are generally deductible for a business seller, and inventory works differently from an expense. Both are covered in are Whatnot fees tax deductible.
Sales tax, GST and VAT
The tax your buyers pay at checkout is not your income and never lands in your payout. In the Weekly Order Report you see it only inside Buyer Paid, where its one effect on you is raising the base the payment processing fee is charged on.
Separately, in some countries tax lands on the fees themselves: GST for Australian sellers and VAT where it applies, reported in the file's two fee tax columns. The current rates and the regional differences live in our guide to Whatnot fees.
The records that make tax time painless
Four things, kept all year: every sale with its fees (the Weekly Order Report gives you this weekly), what each purchase lot cost, the other costs of running the business, and the lots that died. That last one matters more than sellers expect: inventory you wrote off is part of your real result, and BreakCount's sales history marks every write-off as flowing to your tax records as a loss.
Our guide to how to track your profit on Whatnot compares the honest ways to keep those records. BreakCount keeps all four in one place: import the weekly file, add one cost per lot, and the year's net profit is a number you can hand over rather than a spreadsheet you owe someone. Your data exports as CSV whenever you or your accountant want it.
