Sold Your Old Couch at a Loss? The 1099-K Doesn’t Know That. What Casual Sellers Must Do When the Form Overstates Income
A form arriving this January will tell the IRS exactly how much you received for that old couch, and it will say nothing about what you paid for it five years ago. What you do between now and April depends…

You paid $1,400 for a couch in 2019 and sold it on Facebook Marketplace for $300 last weekend. Come January, a form may arrive telling the IRS you received $300 in income, with nothing about the $1,100 loss.
That is the structural problem with Form 1099-K. It reports gross payments, not profit, and not taxable income. For the retiree clearing out a garage or the parent unloading a decade of kids’ gear, the form almost always overstates what the tax code actually cares about. The fix is not complicated, but the documentation proving your side of the story must be gathered now, in August, while you still remember what you paid and receipts exist.
Most Casual Sellers Will Not Get a Form This Year
After years of threshold confusion, the rules for tax year 2026 are settled. A third-party settlement organization, meaning payment apps and marketplaces like Cash App, eBay, Etsy, PayPal, and Venmo, must issue a 1099-K only when a user clears more than $20,000 in gross payments AND more than 200 transactions on a single platform during the calendar year. Both conditions. Not either.
If you sold four pieces of furniture and a bike this summer, you are nowhere near that line. The current threshold is genuinely high, and that is good news for casual sellers.
Why You Might Get One Anyway
Two situations produce a form even for a non-business seller. The first: some platforms, eBay being a named example, may still issue a 1099-K even when activity falls below the reporting threshold. Their internal policy controls what they send.
The second: a high-volume year. Downsizing an entire house, liquidating a deceased parent’s collection, or selling a lifetime of one hobby can push a casual seller past $20,000 and 200 transactions. A separate form is issued by each TPSO where the requirement is met, so a seller active on three platforms could receive three forms.
Ignoring any of them is not an option. The 1099-K is an information return, and the IRS receives a copy. A form left unaddressed on your return can trigger a notice or audit.
Three Buckets, One Form, No Distinction
The form treats every dollar the same. The tax code does not. A single seller can have all three in one year on one platform:
- Personal item sold at a loss. The couch. The used stroller. Most clothing. That income is not taxable. The loss cannot be deducted from other income, but you can zero out the gross amount reported on the 1099-K for that sale so you do not pay tax on it.
- Personal item sold at a gain. If you sell a personal item for more than you originally paid, the gain, less expenses, is taxable income.
- Goods or services as a business or side hustle. Taxable, but related expenses may be deducted from the gross amount.
The IRS publishes guidance on how to report each bucket on your return. Ask your preparer or start at IRS.gov for the current line placement. Do not guess.
Collectibles: The Overlooked Bucket
The bucket most casual sellers overlook is the second one. Sports cards, jewelry, watches, mid-century furniture, and vintage items can appreciate. A watch bought for $2,000 in 1998 and sold for $6,000 today produces a real taxable gain, even for someone who never considered themselves a collector. If the item is worth more than you paid, the receipt showing your original cost limits the taxable amount to the actual gain rather than the entire sale price.
What Proves a Loss, and Why August Is the Deadline
The 1099-K arrives in January or February. The receipts that defend it existed months or years earlier. What counts as proof: original receipts, credit card or bank statements from purchase, order history in an Amazon or retailer account, even a photo of a price tag. Reconstructing this in April for items sold last summer is far harder than saving it now.
One trap to avoid: splitting sales across platforms to stay under $20,000 does not change your tax bill. The threshold is a reporting trigger, not a tax exemption. Whether or not a form is issued, a gain on a personal item is taxable and a loss is not deductible.
A Short List for the Rest of 2026
- Keep a running log: item, date sold, sale price, original cost, platform. A spreadsheet or notebook works.
- Download your order histories from major retailers now, while accounts and orders are still there.
- If you have genuine side-hustle activity, keep it on a separate account or platform from personal sales.
- Do not throw away receipts for higher-value items you plan to sell.
- If a form arrives next winter that looks wrong, contact the issuing platform about a correction. Do not ignore it.
This is general information, not tax advice. A qualified preparer can confirm exactly where each bucket lands on your return.
