Sneaker Resale Tax Guide 2026: Schedule C for eBay and Mercari Sellers

By Darrian Belcher · Published July 25, 2026 · Updated July 25, 2026

Nobody gets into flipping sneakers because they love tax forms. But if you sold pairs on eBay, Mercari, or StockX this year, taxes are part of the business whether you treat it like one or not — and the sellers who get surprised in April are almost always the ones who ignored this stuff in July.

This article is general information, not tax advice. I run a sneaker resale business (404 Sole Archive), but I'm not a CPA, an enrolled agent, or your tax professional. Tax law changes, your situation is specific to you, and the dollar thresholds mentioned below have shifted multiple times in recent years. Before you file anything, consult a qualified tax professional who can look at your actual numbers.

With that on the record, here's the working knowledge every reseller should have: what a 1099-K actually means, why gross sales are not income, how Schedule C and COGS work, and the hobby-versus-business distinction that decides which rules apply to you.

The 1099-K: What That Form Actually Is

A 1099-K is an informational form that payment platforms — eBay, Mercari, StockX, PayPal, and the rest — send to you and to the IRS reporting your gross payment volume for the year. Two things to burn into your brain about it:

• The threshold keeps moving. Congress and the IRS have changed and delayed the 1099-K reporting threshold several times over the past few years. Do not rely on any specific dollar figure you read in a blog post, including this one — check the current IRS 1099-K threshold for the tax year you're filing, because it has genuinely changed several times.
• No form does not mean no taxes. This is the big one. Taxable income is taxable whether or not a platform sends you paperwork. The 1099-K threshold determines when the IRS gets a copy automatically — it does not determine whether you owe tax on your profit. If you profited flipping shoes, that's reportable income at any volume.

The flip side matters just as much: a 1099-K reports gross sales, not profit. If your form says $30,000, that is not what you owe tax on. Which brings us to the most important concept in reseller taxes.

Gross Sales Are Not Income: Enter COGS

Say you sold $30,000 worth of sneakers this year. To sell them, you spent $19,000 buying the pairs. That $19,000 is your cost of goods sold (COGS) — and it comes off the top before anything is taxed.

Then stack your other business expenses: platform fees, shipping labels, boxes and packing supplies, mileage to outlets and meetups, software subscriptions, a cut of your phone bill if you use it for the business. In this example, maybe that's another $5,000. Your actual taxable profit is around $6,000 — a fifth of what the 1099-K shows.

The catch: you only get to subtract what you can substantiate. That means records — what you paid for each pair, when, and where, plus receipts for expenses. In my experience, this is where most resellers bleed money. They can't prove what they paid for inventory sourced with cash a year ago, so on paper their "profit" looks way bigger than reality. Track your buy cost on every pair the day you buy it. Your future self at filing time will thank you.

Hobby vs Business: The Distinction That Changes Everything

The IRS treats hobby sellers and business sellers very differently, and the difference is brutal for hobbyists.

• Business sellers report income and expenses on Schedule C. You deduct COGS, fees, shipping, and other ordinary business expenses, and you pay income tax plus self-employment tax on the net profit. A loss year can generally offset other income (rules apply).
• Hobby sellers must still report income, but under current rules hobby expenses are generally not deductible against that income. Read that again: as a hobby, you can owe tax on revenue you didn't really profit from.

What makes you a business instead of a hobby? The IRS looks at factors like whether you operate in a businesslike manner, keep real records, put in regular time and effort, depend on the income, and have a genuine profit motive. There's no single magic test, and this is exactly the kind of gray area where a tax professional earns their fee. But broadly: if you're sourcing pairs specifically to flip, tracking your numbers, and doing it consistently, you're likely running a business — and Schedule C treatment is usually far better math for you anyway.

One more distinction: cleaning out your closet and selling your own used pairs for less than you paid for them is generally not taxable profit at all — you sold personal items at a loss. Reselling is different because you acquired the inventory to profit.

Schedule C: The Reseller's Tax Form

Schedule C (Profit or Loss from Business) attaches to your regular 1040. For a sneaker reseller, the flow looks like this:

1. Gross receipts — everything you collected from sales across all platforms.
2. Cost of goods sold — what you paid for the pairs you sold this year, computed with beginning inventory, purchases, and ending inventory. Note that pairs still on your shelf at year end are generally not deductible yet — COGS applies when the pair sells.
3. Expenses — the categories below.
4. Net profit — what flows to your 1040 and gets hit with income tax plus self-employment tax (roughly 15.3% for Social Security and Medicare, on top of income tax).

That self-employment tax surprises every first-year reseller. If you're profiting real money, look into quarterly estimated payments so you're not writing one painful check in April — another thing to ask your tax pro about.

Deductions Sneaker Resellers Commonly Miss

Every legitimate expense reduces your taxable profit. Commonly missed ones:

• Platform fees — final value fees, promoted listings, payment processing, store subscriptions. These add up to thousands at volume; I showed the per-sale math in my eBay fees breakdown.
• Shipping — labels, boxes, tape, poly bags, bubble wrap.
• Mileage — driving to outlets, thrift stores, meetups, and the post office, tracked contemporaneously (date, miles, purpose).
• Software and subscriptions — inventory tools, listing tools, price-tracking apps. My SoleOps subscription is a deductible business expense for me, same as any reseller software you use, whether that's a $9.99 Starter plan or a spreadsheet app.
• Supplies and equipment — lighting for photos, cleaning supplies, shelving, that scale you weigh boxes on.
• Home office — potentially, if you use space regularly and exclusively for the business. Strict rules; ask your tax pro.
• Authentication and return costs — legitimizers, return shipping you ate, refunds.

The theme: none of this counts if you can't document it. A shoebox of faded receipts is technically records, but per-pair digital tracking of cost, fees, and net profit is what makes filing painless — and it's the same data that tells you whether you're actually profitable per platform, which I get into in my Mercari vs eBay vs StockX comparison.

Multi-Platform Sellers: Watch for Double Counting

If you sell on eBay, Mercari, and StockX, you may receive multiple 1099-Ks. Your gross receipts on Schedule C should reconcile against the total of all of them — the IRS matches these forms against your return. Keep per-platform records so you can explain every number, and watch for edge cases like refunded orders and cancelled sales that can make a 1099-K's gross figure higher than what you actually kept. Adjustments are handled on the return, not by ignoring the form — one more spot where a professional is worth it.

My Actual System (Do This Starting Today)

You don't need to be a bookkeeper. You need five habits:

1. Record the buy price, date, and source the day you acquire a pair.
2. Record the sale price, platform, fees, and shipping cost the day it sells.
3. Snap or forward every receipt into one folder as it happens.
4. Log business mileage in the moment, not from memory in April.
5. Review your real net profit monthly, per platform, so nothing is a surprise.

Do that all year and filing season becomes an export, not an archaeology dig.

The Bottom Line

Sneaker resale tax comes down to three truths: profit is taxable with or without a 1099-K, gross sales are not profit, and records are the difference between paying tax on your real net and paying tax on numbers you can't defend. Treat the flipping like a business, keep your books like a business, and then — seriously — take those clean books to a tax professional and let them handle the parts that actually change year to year. That combination is cheaper than any of the alternatives.
