If you sell cards on eBay, Whatnot, Mercari, PayPal, StockX, COMC, or Fanatics Live, Form 1099-K is either in your inbox already or on its way. It is the most misunderstood tax form in the hobby. Every January, card sellers make one of two expensive mistakes with it: they ignore it, or they pay tax on the whole number. Both are wrong. Both are avoidable with twenty minutes of understanding.
This guide covers what a 1099-K for a card seller actually reports, the federal threshold under OBBBA, which platforms issue the form, the state thresholds that trigger at far lower volume, how to run the 1099-K reconciliation against your card reseller Schedule C, what the IRS matching program does when the numbers disagree, and how KKATC Cards automates the whole exercise. An FAQ at the end answers the eight questions card sellers ask most.
What a 1099-K actually is
Form 1099-K is an information return, not a tax bill. The legal authority is Internal Revenue Code §6050W, which requires third-party settlement organizations — payment processors and online marketplaces — to report the gross dollar amount they processed for you to both you and the IRS.
Key word: gross. The 1099-K reports every dollar that flowed through the platform on your behalf, before the platform took its cut, before shipping, before refunds, before the cost of the cards you sold. It is not your profit. It is not what you owe tax on. It is the starting point of a reconciliation that lives on your Schedule C.
A W-2 works the same way: gross wages get reported, and the actual tax bill is calculated after deductions. Same logic here, in a self-employment context. And under IRC §61(a), all income is taxable whether or not a form reports it. The 1099-K does not create the tax obligation — it tells the IRS what the platform saw.
The federal threshold — $20,000 AND 200 transactions
For tax year 2025 and forward, the federal reporting threshold is $20,000 in gross payments AND more than 200 transactions per platform per calendar year. Both conditions must be met. Either one alone does not trigger a federal 1099-K. This was set by the One Big Beautiful Bill Act, P.L. 119-21, which restored the original threshold after several years of legislative whiplash.
The history explains the confusion in every reseller forum:
- Pre-2022: $20,000 AND 200 transactions
- American Rescue Plan Act of 2021: lowered to $600 with no transaction floor
- IRS implementation: delayed by Notice 2023-10, then Notice 2023-74 (transition years at $20K/200 and $5,000)
- OBBBA, P.L. 119-21: restored $20,000 AND 200 transactions permanently
If someone in a group chat tells you the threshold is $600, they are quoting a law that was repealed before it ever fully took effect. The $600 figure still matters — but at the state level, covered below.
Which platforms issue 1099-Ks to card sellers
Any third-party settlement organization that processes payments on your behalf must issue a 1099-K when thresholds are met. For card sellers that includes:
- eBay — the largest source of 1099-K eBay cards questions; issues for U.S. sellers crossing the threshold
- Mercari — issues for sellers crossing federal or state thresholds
- PayPal — Goods and Services payments only; Friends and Family is not reported
- Venmo — business-profile payments are reportable
- Whatnot — processes sales for live sellers
- COMC — issues for cleared sellers
- StockX — issues for cleared sellers
- Fanatics Live, formerly PWCC Live — issues for cleared sellers
- Stripe — back-end processor for many card platforms; may appear as the filer
Each platform reports independently. If you sell on three platforms, you may receive three 1099-Ks, and each one is a separate threshold calculation. None of them talk to each other. Your Schedule C is where they all meet.
State thresholds trigger long before federal
Several states set their own 1099-K thresholds well below the federal level. If you operate from one of these states, or the platform sources your sales there, the state gets a form even when the IRS does not:
- Rhode Island: $100
- Massachusetts, Vermont, Virginia, Maryland, District of Columbia: $600
- New Jersey: $1,000
- Illinois: $1,000 AND 4+ transactions
A card seller in Massachusetts can trigger a state 1099-K with two slabs. The state-issued form still requires reporting on your federal return, even when the federal threshold was never met.
The most common mistake card sellers make
Treating the 1099-K number as taxable income. It is not. It is gross receipts. Your taxable income is gross receipts minus cost of goods sold minus business expenses.
A card seller who received a $15,000 1099-K from eBay but spent $18,000 buying cards has a net loss — not a $15,000 tax bill. The 1099-K is the starting point of the Schedule C calculation, not the ending point.
Run the numbers on a more typical year: $30,000 gross on eBay, $9,000 in card purchases sold through, $3,000 in shipping, $3,000 in platform fees. Net profit is $15,000. The 1099-K says $30,000. A seller who pays tax on the full $30,000 — at a 22% federal bracket plus 15.3% self-employment tax — hands the IRS $5,000 to $7,000 that was never owed. That is what sports card taxes on 1099 income look like when nobody does the reconciliation.
How to reconcile your 1099-K to your Schedule C
Gross receipts on Schedule C Line 1 must equal or exceed the total of every 1099-K you received. If Line 1 comes in lower with no explanation, the IRS matching program flags it. The reconciliation is five steps:
- Pull the annual sales report from every platform you sold on
- Add up all 1099-K amounts, platform by platform
- Confirm the total matches Schedule C Line 1 — gross receipts from all sources, including sales below the platform threshold that generated no form
- Document any difference with an explanation: refunds and returns (Line 2), sales tax the platform collected and remitted, personal items sold that do not belong on Schedule C
- Work the rest of the return: COGS on Line 4 via the Part III calculation (beginning inventory + purchases − ending inventory), operating expenses on Lines 8-27, net profit on Line 31
Line 31 is what you pay tax on, plus self-employment tax under §1401 if net earnings exceed $400. For a card dealer electing the IRC §471(c) small-business inventory method, the COGS number comes straight out of your per-card cost basis records — which is exactly why those records need to exist all year, not just in April.
What happens if your 1099-K does not match your Schedule C
The IRS information return matching program — the examination framework is IRM 4.10.4.3.1 — compares every 1099-K it receives against the return you filed. The comparison is automatic. No human reads your return before the notice goes out.
A mismatch triggers a CP2000 notice: a proposed adjustment, with tax, interest, and often an accuracy-related penalty computed on the assumption that the entire unexplained difference is profit. This is not an audit. It is a matching discrepancy, and it is the single most common way card resellers end up in correspondence with the IRS.
The response requires documentation: your platform sales records, your reconciliation showing actual gross receipts, and the explanation for any difference. Sellers who kept card-by-card records respond in an afternoon. Sellers who did not spend weeks reconstructing a year of sales from screenshots. Silence is the trigger, and silence is also the worst response — an unanswered CP2000 becomes an assessment.
How KKATC Cards handles 1099-K reconciliation
KKATC Cards tracks every sale by platform from the moment it happens. The export's 1099-K Reconciliation sheet shows your gross sales by platform with transaction counts and federal/state threshold flags. Use this alongside your Form 1099-K from each platform to reconcile any differences — refunds, sales tax the platform collected and remitted, and sub-threshold platforms that issued no form are common sources of variance.
The export ties the reconciliation directly to Line 1, runs COGS through the IRC §471(c) methodology on per-card cost basis, and stamps the authority reference on every line. When the CP2000 question is "prove your gross receipts," the answer is a workpaper, not a shoebox. That is the difference between a card seller tax tracker and a spreadsheet: the tracker is built for the moment someone checks.
FAQ — the eight questions card sellers ask most
Do I have to report card sales if I did not receive a 1099-K?
Yes. Under IRC §61(a) all income is taxable regardless of whether a form is issued. The 1099-K threshold determines whether the platform reports to the IRS — not whether you owe tax.
What if I received a 1099-K but sold at a loss?
Report the gross receipts on Schedule C Line 1 and deduct your cost of goods and expenses. A net loss is possible and legal. Document your cost basis — the loss is only as defensible as the records behind it.
Can I deduct eBay fees from my 1099-K amount?
No. eBay fees are a Schedule C expense on Line 10. Your gross receipts on Line 1 should match the gross sales reported on your 1099-K, before any fee deduction. Netting fees out of Line 1 creates exactly the mismatch the matching program looks for.
What if my 1099-K includes personal sales not related to my card business?
Report only business sales on Schedule C. Document the non-business sales separately. Personal property sold at a loss is generally not deductible and does not belong on Schedule C.
Do refunds reduce my 1099-K?
Platforms handle refunds differently. eBay generally reduces the 1099-K for refunds processed through the platform. PayPal may not. Check the annual report from each platform to confirm what the form includes, and carry any refunds the form did not net out on Schedule C Line 2.
I received a 1099-K but I am just a hobbyist, not a business. What do I do?
The IRS evaluates hobby versus business status under nine factors, including profit motive and regularity of activity. If you buy and resell cards regularly with the intent to profit, you are likely a dealer filing Schedule C. Hobbyists report the income with no deduction for operating expenses. Either way, the 1099-K gets reconciled — the classification changes the deductions, not the reporting obligation.
What is the difference between a 1099-K and a 1099-NEC for card sellers?
A 1099-K reports payment processing volume from platforms under §6050W. A 1099-NEC reports non-employee compensation under IRC §6041A — relevant if you are paid for services like card consulting, breaking on someone else's stream, or content creation. Both flow into Schedule C, but they report different things and reconcile separately.
Does KKATC Cards help with 1099-K reconciliation?
Yes. KKATC Cards tracks gross receipts by platform in real time. The Schedule C export includes a reconciliation sheet that ties your total sales to each 1099-K received. No end-of-year reconstruction required.
The bottom line
The 1099-K is a reconciliation prompt, not a tax bill. Receiving one means a platform processed enough volume to report — nothing more. Your Schedule C does the actual math: gross receipts by platform, COGS card by card, expenses with receipts, net profit on Line 31. Track it all year and January is a formality. Track nothing and January is a CP2000 waiting to happen.
