Reseller Taxes: 1099-K Explained
Reseller taxes 1099-K explained in plain terms: Form 1099-K reports the GROSS payments a marketplace processed for you — not your profit. Under current federal rules, a platform sends you a 1099-K when you exceed $20,000 AND 200 transactions in a calendar year on that platform, and some states set lower thresholds. You are generally taxed on profit (sales minus costs), not on the gross number — but only if you can prove your costs with records.
Not tax advice. This guide explains how 1099-K reporting generally works for US resellers. Tax rules change and vary by state and situation — confirm your own position with a tax professional. See our disclaimer.

What is a 1099-K?
Form 1099-K is the information return that payment processors and marketplaces use to report payments they handled for you. When you sell through eBay, Etsy, Mercari, Poshmark, Depop, Whatnot, Facebook Marketplace shipped sales or similar platforms, the platform is the payment settlement organization: it collects the buyer’s money, takes its fees, and passes the rest to you. Each January it sends you (and the IRS) a 1099-K for the previous calendar year showing the gross amount it processed.
The key word is gross. The 1099-K total includes the item price plus any shipping the buyer paid and any sales tax the platform collected on the sale. It does NOT subtract marketplace fees, your item cost, your actual shipping cost, packaging or refunds in the way you might expect. That is why a 1099-K total almost always looks much larger than the profit you actually made — and why the records in this guide matter more than the form itself.
Who gets a 1099-K?
| Rule | Threshold | What it means |
|---|---|---|
| Federal (per platform) | Over $20,000 AND over 200 transactions | Both conditions must be met on that platform |
| Some states | Lower — $600 in several states | Check your own state’s rule; it may differ |
| Below threshold | No 1099-K from that platform | Income is still generally reportable |
Two details catch resellers out. First, the federal threshold applies per platform, not across all your selling combined: $15,000 on eBay plus $10,000 on Mercari is below $20,000 on each platform, so neither would send a federal 1099-K — though a lower state threshold could still trigger one. Second, not receiving a 1099-K does not mean the income is tax-free. It only means no form was required; income from selling is generally reportable whether or not a form arrives.
Why your 1099-K looks bigger than your profit
Take a reseller who sells 400 items at $50 on eBay in a year, with $10 cost and $5 actual shipping per item and no shipping charged to buyers:
| Line | Amount |
|---|---|
| Gross payments (what the 1099-K shows) | $20,000.00 |
| Minus eBay fees (400 × $7.20) | $2,880.00 |
| Minus item costs (400 × $10) | $4,000.00 |
| Minus actual shipping (400 × $5) | $2,000.00 |
| Real profit | $11,120.00 |
The IRS sees $20,000; your real profit is $11,120. The $8,880 gap is fees, costs and shipping — and you only get credit for it if your records prove it. Run the same math on your own sales with the reseller profit calculator before tax season, not during it.
What to track all year
If you only track one thing, track cost per item. Everything else flows from it. For every sale, record: the item and its cost, the sale price, the shipping you charged, your actual postage and packaging cost, the platform fees, and any refund or return. For your business as a whole, also track packaging supplies, postage supplies, software and listing-tool subscriptions, and any other ordinary costs of selling. The inventory tracking guide (coming with the Phase 2 guides) shows a simple spreadsheet layout that captures all of this in one place.
Two habits make tax season painless. First, reconcile monthly: compare each platform’s sales report to your own records while the month is still fresh, so a missing refund or a wrong fee is caught early. Second, keep business money separate where you can — a dedicated account or card for reselling turns a year of detective work into a single statement. Save platform fee reports and payout statements as you go; platforms do not always keep them available indefinitely.
How resellers generally report
Most individual resellers who sell regularly report as a business on their tax return — commonly on Schedule C (Profit or Loss From Business) for sole proprietors — where gross receipts are reduced by the cost of goods sold and ordinary business expenses, including marketplace fees and shipping. Occasional sellers of personal items have different rules, and the line between a hobby, personal sales and a business depends on your facts. That distinction, plus state rules and estimated-tax requirements, is exactly where a tax professional earns their fee: this guide explains the mechanics, not your filing position.
If you expect to owe tax on reselling income, note that the US system is pay-as-you-go: many sellers need quarterly estimated payments rather than one April surprise. Again, the amounts and thresholds depend on your total income — a professional can estimate them in minutes from records like the ones above.
5 record-keeping tips for resellers
- Log cost the day you buy, not the day you sell. Thrift receipts fade and memories do not survive a year of sourcing.
- Record fees per sale, not per month. Platform fee reports give you the exact number — the eBay fee calculator and its siblings help you estimate it in advance.
- Track refunds separately. A refunded sale still appears in gross payments; your records are what prove it was not income.
- Keep shipping receipts. Actual postage is a real cost even when the buyer paid shipping — and the return cost calculator shows how returns change the picture.
- Keep records for at least three years after filing, the general IRS record-keeping window — longer if your state requires it.
Frequently Asked Questions
Do I owe tax if I did not get a 1099-K?
Generally, yes, if you made a profit: not receiving a 1099-K only means no form was required for that platform. Income from selling is generally reportable whether or not a form arrives.
Does a 1099-K mean I owe tax on the full amount?
No. The 1099-K shows gross payments. You generally report profit — gross receipts minus the cost of goods sold and ordinary business expenses such as marketplace fees and shipping — but you need records to support those deductions.
What if my 1099-K amount looks wrong?
Compare it to your own records first, then contact the platform’s support for a correction if the gross total is genuinely wrong. Keep both your records and the platform’s response; do not simply file a different number without documentation.
Do platforms combine my sales for the $20,000 threshold?
No. The federal threshold applies per payment settlement entity, so each platform reports separately. State thresholds vary and may be lower.
What records should a reseller keep?
Per item: cost, sale price, shipping charged, actual postage and packaging, platform fees, and any refund. For the business: supplies, software and other ordinary selling costs, plus platform payout statements.
