Yes, Whatnot sends a 1099-K when you meet the reporting threshold. The 1099-K reports gross transaction amounts — not your profit. Subtract your cost of inventory, Whatnot’s ~8% seller fee, payment processing, and shipping to find your actual taxable income.

Whatnot has transformed the collectibles market. Live auctions, box breaks, and card shows now happen on your phone — and the IRS has noticed. If you’re selling trading cards, Pokémon, sports memorabilia, coins, or any other collectibles on Whatnot, you need to understand how the platform reports your income and what you actually owe. This guide covers everything from the 1099-K threshold to deductible fees, cost basis tracking, and the critical distinction between hobby sellers and business sellers under the tax code.
Does Whatnot Send a 1099-K?
Yes. Whatnot is a third-party settlement organization (TPSO) under IRC §6050W, which requires payment processors and marketplace platforms to report gross payment amounts to the IRS. When you sell on Whatnot and receive payments through the platform, Whatnot is legally required to file Form 1099-K with the IRS — and send you a copy — if you meet the applicable reporting threshold.
Under the rules restored by the One Big Beautiful Bill Act (OBBBA), the 1099-K reporting threshold is $20,000 in gross sales AND 200 or more transactions in a calendar year. Both conditions must be met. If you sold $25,000 worth of cards across 50 transactions, you would not receive a 1099-K because you didn’t hit 200 transactions. If you had 300 transactions totaling $8,000, you also wouldn’t receive one because you didn’t reach $20,000.
Whatnot typically issues 1099-K forms by January 31 for the prior tax year. The form arrives in your Whatnot seller dashboard and by mail. Critically, the amount on the 1099-K is your gross sales — the total dollar amount buyers paid, before any fees, shipping, or cost of goods. This is almost never the amount you actually owe tax on.
Even if you don’t receive a 1099-K because you fell below the threshold, you are still required to report all income under IRC §61, which defines gross income as “all income from whatever source derived.” The 1099-K is a reporting mechanism, not a tax trigger. Your obligation to pay tax exists regardless of whether you receive the form.
Whatnot Gross Sales vs. Actual Profit
The most common mistake Whatnot sellers make is confusing their 1099-K amount with their taxable income. The 1099-K reports gross transaction volume — every dollar that buyers sent through the platform. Your actual taxable income is dramatically lower once you account for the cost of inventory, platform fees, payment processing, and shipping expenses.
Understanding this distinction is critical. If the IRS sees a $5,000 1099-K and you report $0 in income, they’ll send a notice. But if you properly document your expenses and cost basis, you may owe tax on a fraction of that gross amount.
A seller does $5,000 in gross Whatnot sales over a tax year.
| Line Item | Amount |
|---|---|
| Gross sales on 1099-K | $5,000 |
| Minus inventory cost (cards purchased for resale) | −$3,200 |
| Minus Whatnot seller fee (~8%) | −$400 |
| Minus payment processing fees | −$150 |
| Minus shipping costs | −$180 |
| Actual taxable gain | $1,070 |
The 1099-K says $5,000. Your actual taxable income is $1,070 — a 79% reduction. Without proper documentation of these expenses, you could end up paying tax on the full $5,000.
This is why record-keeping matters more than anything else in Whatnot tax compliance. Every receipt for inventory, every shipping label, and every fee statement reduces your tax liability. Whatnot provides seller statements in your dashboard that break down fees and payouts — download these for your records.
Hobby vs. Business for Whatnot Sellers
How the IRS classifies your Whatnot selling activity determines which forms you file and which deductions you can take. This classification matters enormously under IRC §183, the hobby loss rules.
Business sellers (Schedule C): If you regularly go live on Whatnot, purchase inventory specifically for resale, maintain shipping supplies, and treat selling as a profit-seeking activity, the IRS will likely consider you a business. This is the case for most active Whatnot sellers. Business classification means you file Schedule C (Profit or Loss from Business) and can deduct all ordinary and necessary business expenses — inventory costs, fees, shipping, supplies, equipment, and even a portion of your internet and phone bill.
The IRS evaluates nine factors under IRC §183 to distinguish business from hobby activity: the manner in which you carry on the activity, your expertise, the time and effort you invest, your expectation of asset appreciation, your history of income or losses, your track record of success in similar activities, and whether the activity has elements of personal pleasure. Running regular live shows, keeping records, and actively sourcing inventory all point strongly toward business classification.
Hobby or occasional sellers (Schedule D): If you’re selling items from your personal collection — cards you’ve held for years, items you originally bought for enjoyment rather than resale — these are capital asset dispositions reported on Form 8949 and Schedule D. You’ll report the gain or loss on each item individually. For collectibles held longer than one year, long-term gains are taxed at the 28% collectibles rate under IRC §1(h). Short-term gains (items held one year or less) are taxed as ordinary income. Under the hobby loss rules, you cannot deduct losses from hobby sales against other income.
Many Whatnot sellers fall into a hybrid situation — they sell some items from their personal collection and also buy inventory to resell. In that case, you may need to report some sales on Schedule C and others on Schedule D. Keep separate records for each category. See our dealer vs. investor vs. hobbyist guide for the full breakdown.
How to Report Whatnot Income
The reporting path depends on your classification. Here’s a step-by-step walkthrough for each scenario.
Path 1: Business Seller (Schedule C)
If you’re running a Whatnot selling business, follow these steps:
- Gather your records: Download your Whatnot seller statement (showing gross sales, fees, and payouts). Compile all inventory purchase receipts, shipping costs, and supply expenses.
- File Schedule C (Form 1040): Report your gross receipts (the 1099-K amount) on Line 1. Report your cost of goods sold on Line 4. Deduct business expenses (fees, shipping, supplies) in Part II.
- Calculate self-employment tax: Net profit from Schedule C flows to Schedule SE. You’ll owe 15.3% in self-employment tax (Social Security + Medicare) on net earnings above $400, in addition to income tax. This is often a surprise for new sellers.
- Make quarterly estimated payments: If you expect to owe $1,000 or more in tax, the IRS requires quarterly estimated payments (Form 1040-ES) to avoid underpayment penalties.
Path 2: Personal Collection Sales (Form 8949 / Schedule D)
If you’re selling items from a personal collection:
- List each sale on Form 8949: For every item sold, record the description, date acquired, date sold, sale proceeds, and cost basis.
- Classify by holding period: Items held over one year go in Part II (long-term). Items held one year or less go in Part I (short-term).
- Transfer totals to Schedule D: Long-term collectible gains are taxed at a maximum 28% rate. Short-term gains are taxed at your ordinary income rate.
- Address the 1099-K mismatch: If your 1099-K shows $20,000 in gross sales but your actual gains are $3,000, you need to show the IRS the math. Report the full gross amount, then subtract your basis and expenses to arrive at the correct gain.

Tracking Cost Basis for Live-Sold Collectibles
Cost basis — what you paid for an item — is the single most important number in your tax calculation. Without it, the IRS assumes your basis is $0, meaning your entire sale price is taxable gain. For Whatnot sellers, tracking basis presents unique challenges because of how inventory is acquired.
Individual purchases: When you buy a single card or collectible for resale, your basis is straightforward — the purchase price plus sales tax, shipping, and any authentication or grading fees. Photograph every receipt and store them digitally. A simple spreadsheet with columns for item description, date purchased, purchase price, source, and associated costs is sufficient.
Lot purchases: Whatnot sellers frequently buy bulk lots to break down and resell individually. When you purchase a lot of 100 cards for $500, you need to allocate that $500 across every card in the lot based on relative fair market value at the time of purchase. If one card in the lot is worth $200 and the rest are worth $300 collectively, the high-value card’s basis is $500 × ($200 ÷ $500) = $200.
Box break allocations: If you buy a spot in a box break on Whatnot and pull multiple cards, your basis is the break spot cost, allocated across all cards pulled by their relative fair market value at the time of the break. This is the same principle as lot allocation. Document the break cost, what you pulled, and the approximate market value of each card at the time. See our complete cost basis guide for detailed allocation methods, and use our tax calculator to estimate your liability.
Consignment and trade inventory: If you accept items on consignment to sell on your live shows, your basis in those items is $0 — you’re selling them on behalf of someone else. You report the full sale price as income, then deduct the payout to the consignor as a cost of goods sold. Keep written consignment agreements for every item.
Whatnot Fees You Can Deduct
Whatnot charges several fees that directly reduce your taxable income. Under Treas. Reg. §1.263(a)-1(e) (the de minimis safe harbor for business expenses) and general principles of IRC §162 (ordinary and necessary business expenses), the following are deductible:
- Whatnot seller fee (~8%): The platform’s commission on each sale. This is your single largest deductible fee on the platform.
- Payment processing fees: The credit card processing charges that Whatnot passes through (typically 2.9% + $0.30 per transaction). These appear on your seller statement.
- Shipping costs: Postage, shipping labels, and carrier charges for items sold and shipped to buyers. If you offer free shipping, you absorb this cost — and it’s fully deductible.
- Packing and shipping supplies: Bubble mailers, toploaders, penny sleeves, tape, boxes, and any other materials used to ship sold items.
- Camera, lighting, and streaming equipment: If you purchased a camera, ring light, tripod, microphone, or other equipment specifically for your Whatnot live shows, these are deductible as business equipment. Items over $2,500 may need to be depreciated rather than expensed in the year of purchase, though the de minimis safe harbor under Treas. Reg. §1.263(a)-1(f) allows you to expense items up to $2,500 ($5,000 with an applicable financial statement).
- Internet and phone costs: A proportional share of your internet and phone bill attributable to your Whatnot business is deductible. If you use your internet 20% for Whatnot business, 20% of the cost is deductible.
For capital gains sellers (Schedule D filers), platform fees and shipping costs reduce your net proceeds rather than appearing as separate deductions. The effect on your tax bill is the same — subtract fees from the sale price when calculating gain on Form 8949.
Common Whatnot Tax Mistakes
After reviewing thousands of collectibles tax questions, these are the errors we see most frequently from Whatnot sellers:
- Treating the 1099-K as taxable income: The 1099-K is gross sales, not profit. If you report the full 1099-K amount as income without subtracting cost of goods, fees, and expenses, you’ll massively overpay. As shown in our worked example above, actual taxable income can be 80% lower than the 1099-K figure.
- Not tracking cost basis: If you can’t prove what you paid for inventory, the IRS can treat your basis as $0. This means every dollar of revenue becomes taxable. Start a spreadsheet today — date purchased, item description, amount paid, source. Photograph receipts. This single habit can save you thousands in taxes.
- Forgetting self-employment tax: Business sellers on Schedule C owe 15.3% self-employment tax on net profit in addition to income tax. Many new sellers are shocked by this. Budget for it, and make quarterly estimated payments to avoid penalties.
- Ignoring state taxes: Most states tax business income and capital gains as ordinary income. California adds up to 13.3%, New York up to 10.9%. Your combined federal and state rate can exceed 40%. Check our state capital gains guide for your state’s rate.
- Not separating personal and business sales: If you sell from your personal collection AND buy inventory for resale, you need to track these separately. Personal collection sales go on Schedule D; business inventory sales go on Schedule C. Mixing them up creates reporting errors and potential audit triggers.
- Missing the hobby loss limitation: Under IRC §183, if the IRS classifies your activity as a hobby rather than a business, you cannot deduct losses against other income. If you’re consistently losing money on Whatnot, the IRS may reclassify your business as a hobby and disallow your loss deductions retroactively.
