Say you pulled a Pokémon card from a booster pack in 2021 for the price of the pack, watched it get graded a gem-mint 10, and sold it last month for $4,000. Or you flipped a pair of limited-release sneakers you bought at retail for a $600 profit on StockX. Either way, a familiar envelope shows up in late January: Form 1099-K, reporting the gross amount the platform paid you — not your profit, not your cost basis, just the top-line number.
For a growing number of sneakerheads, card collectors, and vintage-toy flippers, that form is the moment a hobby starts looking a lot like a business in the eyes of the IRS. And the rules just changed again.
The 1099-K Threshold Is Back to $20,000 — For Now
After several years of shifting thresholds and delayed enforcement, the 2026 reporting threshold for third-party payment platforms (eBay, PayPal, Venmo, Whatnot, StockX, Cash App for business use) is back to $20,000 in gross payments and more than 200 transactions. The One Big Beautiful Bill Act restored this older, higher threshold after years of confusion around a much lower $600 rule that never fully took effect.
Here's the part resellers consistently get wrong: the threshold only controls whether you receive a form — it does not control whether the income is taxable. If you sold $8,000 worth of graded cards this year and never crossed the reporting threshold, you still owe tax on the profit if the activity rises to the level of a business (or even, in some cases, as hobby income). No 1099-K in your inbox is not the same as no tax obligation.
Hobby or Business? The Distinction That Changes Everything
This is the single most consequential classification question a reseller will answer, because the two paths lead to wildly different tax outcomes.
If it's a hobby:
- Income is fully taxable
- You cannot deduct expenses (grading fees, shipping supplies, marketplace fees, mileage to card shows) — the miscellaneous itemized deduction that used to allow this is gone
- No self-employment tax, but also no Section 179 deductions, no home-office deduction, nothing
If it's a business (Schedule C):
- You deduct cost of goods sold, platform fees, grading and authentication costs, packaging, mileage, and a home office if you dedicate space to inventory
- You may qualify for the Section 199A qualified business income deduction
- But you also owe 15.3% self-employment tax on net profit, on top of income tax
The IRS doesn't ask you to self-certify — it looks at facts and circumstances under the nine-factor test in Section 183 of the tax code. The factors that matter most for a card or sneaker reseller:
- Do you keep books and records like a business? A spreadsheet tracking every purchase and sale is a strong signal.
- Do you operate in a businesslike manner? Sourcing inventory deliberately, tracking margins, adjusting pricing — versus buying whatever you personally like and occasionally reselling extras.
- Time and effort. Regularly attending shows, sourcing wholesale lots, or running a storefront on Whatnot or eBay looks different from an occasional garage-sale flip.
- History of profits or losses. If the activity shows a profit in three of the last five years, the IRS presumes it's a business unless it has strong evidence otherwise. Losing money every year — especially while treating the "losses" as a way to offset a W-2 salary — invites scrutiny.
- Personal pleasure or recreation involved. Genuinely loving cards or sneakers doesn't disqualify you from business treatment, but if the IRS sees a pattern of buying things to keep and only selling duplicates or unwanted items, that cuts against business status.
There's no single bright line. A collector who's been PSA-grading childhood cards and occasionally selling one to fund a new purchase looks very different, on paper, from someone who buys wholesale lots of sealed wax specifically to break and resell singles at a markup. If you received a 1099-K, treat that as a strong signal you're already operating as a business in the IRS's eyes — the burden of proving otherwise falls on you.
Cost Basis: Why "I Paid $20 for That Card" Isn't the Whole Story
Cost basis is the number the IRS lets you subtract from your sale price before calculating gain — and for collectibles, it's usually more than just the sticker price. Basis includes:
- The purchase price itself
- Sales tax paid on the purchase
- Grading and authentication fees (PSA, BGS, CGC submissions)
- Buyer's premiums on auction purchases
- Shipping costs to acquire the item
- Restoration costs that add value (for cards, this is rare and can actually reduce value — but for some collectibles, professional cleaning or repair counts)
On the sale side, you reduce your proceeds by outbound shipping, marketplace/payment processing fees, and insurance during transit. The difference between gross sale price and total cost is your taxable gain — not the raw 1099-K number.
This matters enormously for "grails" — the single high-value pieces (a graded rookie card, a rare Jordan colorway, a sealed vintage set) where getting the basis wrong by even a few hundred dollars meaningfully changes the tax bill. If you bought a raw card for $50, spent $30 grading it, and sold the resulting PSA 10 for $2,000, your basis is $80, not $50 — a small detail that's easy to lose track of a year later without records.
The Two-Account Rule That Prevents Most Reseller Bookkeeping Disasters
Tax professionals who work with resellers consistently point to one habit that separates clean books from a reconstruction nightmare at tax time:
- Never let money sit in PayPal, Venmo, or Cash App balances. Sweep proceeds to a dedicated bank account immediately after each sale.
- Fund every inventory purchase from that same business account or a dedicated card — never from a payment app's floating balance.
When every dollar in and out passes through one bank account, your bank statement becomes a chronological ledger of the business. When money bounces between five payment apps and gets spent directly from those balances, reconstructing a year of activity means combing through eBay, PayPal, Venmo, and StockX exports separately and hoping nothing falls through the cracks. This is the single highest-leverage habit a new reseller can adopt, and it costs nothing to start.
Inventory Tracking Without a Full ERP System
You don't need enterprise inventory software to track sports cards or sneakers correctly — a well-structured spreadsheet (or a plain-text ledger) covering each item is enough:
- Item description (set, card number, or sneaker model/size/colorway)
- Acquisition date and source
- Purchase price + grading/authentication cost + shipping in = total basis
- Sale date, sale price, platform fees, shipping out
- Realized gain or loss
At month-end or quarter-end, this lets you calculate cost of goods sold the standard way: beginning inventory + purchases − ending inventory = COGS. Without it, you're stuck guessing at year-end what you actually still hold versus what you sold — and an inventory count you can't defend is one of the first things an IRS examiner will poke at if you're ever audited.
This is exactly the kind of structured, auditable record-keeping that plain-text accounting is built for: every purchase and sale is a discrete, dated entry you can query, reconcile against a bank statement, and hand to a tax preparer without translation. Beancount.io lets resellers track inventory-style accounts (each grail as its own sub-account, if you want that level of detail) right alongside the bank and payment-platform accounts feeding them, so cost basis and realized gains stay tied to the actual transaction history — not a separate spreadsheet that drifts out of sync.
Collectibles Get Their Own (Higher) Capital Gains Rate
One wrinkle specific to cards, coins, art, and similar items: the IRS treats them as "collectibles" under a special tax category, separate from stocks or real estate. If you hold a card or collectible as an investment for more than a year before selling, long-term gains are taxed at a maximum 28% collectibles rate — higher than the standard 15–20% long-term capital gains rates most investors are used to. Short-term gains (held one year or less) are simply taxed as ordinary income, same as any other short-term sale.
This distinction mostly matters for people holding items as personal investments rather than running an active resale business — a Schedule C reseller's inventory sales are ordinary business income either way, not capital gains. But if you're sitting on a personal collection built over years and deciding whether to sell now, knowing which bucket you fall into changes the math.
Choosing a Business Structure
Once volume and profit reach a point where the activity is clearly a business, resellers often ask about forming an LLC. It's worth separating two different questions:
- Liability protection — an LLC can shield personal assets from business debts or claims, which matters more if you're shipping high volumes or handling large-dollar disputes.
- Tax treatment — a single-member LLC is taxed identically to a sole proprietorship by default (Schedule C). Only electing S-corp treatment changes the tax picture, and that election makes sense at a specific profit threshold, not from day one.
Forming an entity for the sake of "looking more legitimate" without understanding which of these two problems you're solving is a common — and avoidable — mistake. Talk to a tax professional about your specific profit level before filing formation paperwork.
Keep Your Collectibles Business Audit-Ready
Whether you're flipping a few grails a year or running a full-time card and sneaker resale operation, the businesses that survive an IRS inquiry cleanly are the ones with a paper trail: dated purchase records, grading receipts, a single bank account for the flow of funds, and inventory that reconciles to actual sales. Beancount.io offers plain-text accounting that's transparent, version-controlled, and easy to hand off to an accountant — no black-box spreadsheet, no vendor lock-in, just a ledger you fully own. Get started for free and keep your cost basis, inventory, and gains in one auditable place from your very first sale.
