eBay Seller Taxes: The 1099-K Threshold, and What You Owe Without One

The threshold, plainly

For the 2026 tax year — the one you file in early 2027 — the federal reporting threshold is:

More than $20,000 in gross payments AND more than 200 transactions.

Both, not either. This matters, because the $600 figure that circulated for years has been restored to the older, much higher bar by the One Big Beautiful Bill Act.

Worked through:

Then the asterisk: several states set their own, lower thresholds, some as low as $600, and eBay issues according to your state's rule. If you are in one of those states, the federal numbers above are not your numbers. Check your own state before assuming you are under.

The part that causes actual panic

A 1099-K arrives showing $24,000 and the immediate reaction is "I owe tax on $24,000." You do not.

The form reports gross payments processed — the total buyers paid, including the shipping they paid you, and before eBay's fees, before postage, before what the item cost you. It is deliberately the largest possible number.

The same $24,000 year, unpacked:

Tax is assessed on the $7,200, not the $24,000. Which is exactly why the records matter — without them, you cannot substantiate any of the four subtractions, and the IRS's starting position is the number on the form.

The rule that matters more than the threshold

The threshold governs the form, not the obligation.

You owe income tax on profit whether or not a 1099-K is issued. A seller doing $9,000 across 90 sales gets no form and still reports the profit. This is not a loophole that closed — it was never a loophole.

The mirror-image rule is the one that saves most casual sellers money:

Selling your own used possessions at less than you paid is generally not taxable income. The couch you bought for $800 and sold for $200 is a personal loss, not a gain, and personal losses of that kind are not deductible either. Where people get hurt is receiving a 1099-K for exactly those sales and not knowing how to report them — the form arrived, so it has to be addressed on the return, but the result can still be zero taxable gain.

That is a conversation for a tax preparer with your actual numbers. What you need from this article is to not ignore the form, and to not assume it is a bill.

What actually counts as a deduction

If you are reselling as a business — buying to resell, with a profit motive — the ordinary and necessary costs come off. The realistic list:

• Cost of goods sold. What you paid for the item. The single biggest line, and the one people fail to record.
• eBay fees. Final value fees, per-order fees, store subscription, promoted listing fees.
• Actual shipping costs. The postage you bought. Note: shipping the buyer paid you is income and the label is an expense — record both, do not net them in your head.
• Packaging. Mailers, boxes, tape, labels, thermal paper.
• Mileage to source, if you keep a log that a human could audit.
• A portion of home costs if you have a space used regularly and exclusively for the business. This one has real rules — get advice before claiming it.
• Software and tools used to run the business.

Most of this lands on Schedule C if you are a sole proprietor. If you are profitable at any scale, self-employment tax is the line that surprises people more than income tax does.

The record-keeping that takes ten seconds an item

This is the whole article in one section.

Track four fields, per item, at the moment you acquire it:

1. Date acquired
2. What it is
3. What you paid
4. Where you bought it

Then two more when it sells: date sold and what it sold for. eBay's own reports cover the sale side well; nothing covers the purchase side but you.

A spreadsheet is genuinely enough for the first year or two. The tool does not matter. The discipline does, and the discipline is entirely about capturing cost basis at purchase, because reconstructing it in April from a shoebox is the job everyone swears they will never do twice.

If you sourced a $40 lot of twelve items, allocate it — $3.33 each, or weight it toward the pieces you expect to carry the lot. Write down which method you used and then be consistent. Consistency is defensible; improvising per-item is not.

What I do differently now

I stopped keeping the purchase record separate from the listing record.

For years I had receipts in one place and listings in another, and the join between them was my memory. It worked at thirty items a month and completely fell apart above that, because the failure is silent — you do not notice a missing cost basis until you need it, and by then the receipt is gone.

Now the cost goes in at the same moment the item enters inventory, attached to the item, before it is ever photographed. If it did not get a cost, it does not get listed. That one rule removed the entire April problem.

The other change: I stopped netting shipping in my head. Buyer-paid shipping is income and the label is an expense, and treating them as a wash understates both sides. It makes no difference to the profit, and a large difference to whether the numbers reconcile against the 1099-K.

The honest limits

I am not a tax professional and this is not tax advice. It is a description of how the reporting works, sourced to eBay's own 1099-K guidance and the IRS explainer.

Three specific things worth paying a professional for:

• Hobby versus business classification. It changes what you can deduct, and the test is about profit motive and conduct, not what you call yourself.
• Your state's threshold and income tax treatment, which can differ substantially from the federal picture.
• The first year you are meaningfully profitable. Quarterly estimated payments, self-employment tax, and inventory accounting all arrive at once, and one hour of advice is cheaper than the penalty.

None of that changes the thing you should do today, which is write down what you paid for the next item you buy.
