Does Whatnot send tax forms? The 1099-K, explained

For US sellers, the federal trigger is crossing more than $20,000 received through the platform across more than 200 transactions, per the IRS as of 28 June 2026, and your state can set a lower one. The form in question is the 1099-K, the information return that payment platforms and online marketplaces file when a seller crosses a reporting threshold. Under every threshold that applies to you, no form is required; over one, a form goes to you and to the tax authority behind it. Either way, the form changes nothing about what you owe, and this article is records guidance, not tax advice.

Per the IRS page "Understanding your Form 1099-K", as updated 28 June 2026: online marketplaces are required to report payments on a 1099-K when the total you receive for goods or services through the platform exceeds $20,000 across more than 200 transactions. Both parts matter; a seller under either number is under the threshold.

Thresholds have moved before and can move again, so treat the number as a snapshot with a date on it, and check the IRS's own page in January rather than a year-old blog post, this one included.

The 1099-K reports gross payments: the unadjusted total that moved through the platform to you. It does not know the commission and processing fees that came out of every sale, the refunds you gave, the shipping you paid, the giveaways you ran, or what your inventory cost. Every one of those stands between the form's number and your real net profit. The fees, at least, are generally deductible for a business seller; are Whatnot fees tax deductible covers that side.

That gap is where sellers get hurt at tax time: report the form's gross without the costs and you overstate your income, sometimes badly. A breaker who grossed $30,000 on cases that cost $22,000 did not make $30,000, and only their records can say so.

The reverse trap is quieter: staying under the threshold and concluding the income does not exist. Taxable income is taxable from the first dollar whether or not any form reports it. The practical takeaway is the same in both directions: your own records, not the form, are the source of truth. The wider picture, including what actually gets taxed, is in Whatnot taxes for sellers, and a form does not decide whether your selling is a hobby or a business either. Nothing is withheld from a Whatnot payout, which is why some sellers pay quarterly estimated taxes rather than settling up once a year.

A mismatch is normal, and the cause is structural: the form counts gross payments while you count what you kept. The full walk from a form's gross to your own net profit, including the refund-timing trap that straddles a year boundary and the case where two forms arrive at once, is in why you got two 1099-Ks for one year of Whatnot sales.

So reconcile rather than dispute. Pull the annual Seller Statement for the year, line your own per-sale records up against it, and note the differences the form cannot see. If a form issued by Whatnot through Stripe is genuinely wrong, Whatnot Support is the route to fixing it.

Yes, once you cross a reporting threshold and cashed out through Stripe. Per Whatnot's 1099-K article for US sellers, updated 13 March 2026, a US seller with a connected Stripe account who exceeds the threshold gets a 1099-K that Whatnot issues and files with the tax authority, with no opt-out. A seller who cashed out only through PayPal gets no Whatnot form; PayPal may send its own, which is covered in why you got two 1099-Ks.

Not being reported is not the same as not being taxable, and Whatnot's own article says so too. What that means for a seller under the threshold is above, in no form does not mean no tax.

The preparation is identical whether a form comes or not: every sale with its fees, one cost per purchase lot, refunds netted, write-offs recorded. The Weekly Order Report hands you the sales side weekly; BreakCount adds the cost side and keeps a year of real net profit ready to reconcile against whatever January brings.
