Yes, income from eBay sales is taxable under federal law. What you actually owe depends on three things: whether you’re selling personal belongings for less than you paid, whether the IRS treats your selling as a hobby, or whether it qualifies as a business. Each path uses different forms, allows different deductions, and can produce very different tax bills on the same dollar of sales.
Selling Your Own Stuff at a Loss
This is the scenario that trips up the most casual sellers. You clean out the garage, sell a used couch for $200 that you originally paid $800 for, and later a Form 1099-K arrives showing $200 in payments. You don’t owe tax on that sale. When you sell a personal item for less than you paid, the transaction is a return of capital, not income.
You do still need to account for it on your return so the IRS doesn’t see the 1099-K figure as unreported income. There are two accepted ways to handle it. You can report the gross amount at the top of Schedule 1 (Form 1040) and enter an equal offsetting amount so the net is zero. Or you can report the sale on Form 8949, which flows to Schedule D, listing your sale price against your original cost basis to show the loss.1Internal Revenue Service. What to Do With Form 1099-K
Either method zeros out the reported income. One boundary to know: you cannot deduct the loss from a personal item sale against your wages or other income. Personal losses just wash to zero.
If you sell a personal item for more than you originally paid, say a vintage guitar you bought for $400 that sells for $1,200, the $800 difference is a taxable capital gain. Receipts or other proof of your original purchase price are what let you defend either outcome if the IRS asks.
When eBay Reports You to the IRS
eBay sends Form 1099-K to the IRS and to you when your account crosses the federal reporting threshold. The threshold has changed several times in recent years. Under current law, restored by the One Big Beautiful Bill Act, eBay is only required to issue a 1099-K when a seller receives more than $20,000 in gross payments across more than 200 separate transactions in a year. Both conditions have to be met.2Internal Revenue Service. Form 1099-K FAQs
Some states enforce their own lower reporting thresholds, so you may receive a state-level form even if you don’t cross the federal line. Check your state’s department of revenue for current numbers.
Two things are worth being clear about. First, the form is an information document. Its presence or absence doesn’t change your tax obligation: you owe tax on income from selling whether or not a 1099-K shows up. Second, the number on the form is not your taxable income. It’s the gross amount of payments processed through your account, including shipping charges and any sales tax that eBay collected on your behalf. That gross figure has to be reconciled to your actual income before you calculate tax.
Hobby or Business? Why It Changes Everything
If your selling goes beyond clearing out personal items, the IRS wants you to determine whether it’s a for-profit business or a not-for-profit hobby. The label controls which forms you file and which deductions you can take.3Taxpayer Advocate Service. Hobby vs. Business Income
A business reports on Schedule C, attached to Form 1040. You subtract cost of goods sold and operating expenses from gross receipts and pay tax on the net profit. A hobby reports income on Schedule 1, Line 8j, and under current law you cannot deduct any hobby expenses at all. The Tax Cuts and Jobs Act suspended miscellaneous itemized deductions from 2018 through 2025, and the One Big Beautiful Bill Act of 2025 made that elimination permanent.4Tax Policy Center. How Did the TCJA and OBBBA Change the Standard Deduction and Itemized Deductions
What that means in practice: if you sell $3,000 worth of craft supplies as a hobby and spent $2,500 on materials, you owe income tax on the full $3,000. The $2,500 disappears. Hobby losses also can’t offset your wages or investment income.5Internal Revenue Service. Know the Difference Between a Hobby and a Business
The IRS looks at whether you have a genuine profit motive, weighing factors like whether you keep books and a separate bank account, how much time you dedicate to sourcing and shipping, whether you’ve earned profits in past years, whether you depend on the income, and whether you’ve sought advice on making the activity profitable. No single factor is decisive. A seller who spends 20 hours a week sourcing inventory and tracks every purchase in a spreadsheet looks very different from someone who occasionally lists items they no longer want.
If you’re selling consistently and spending real money on inventory, shipping, and fees, business classification is almost always the better tax outcome, because the alternative is paying tax on your gross with nothing to deduct. If the IRS reclassifies a business as a hobby during an audit, you’ll owe back taxes on every expense you deducted.
How Business Sellers Calculate What They Owe
Schedule C income is net profit: gross receipts minus cost of goods sold minus operating expenses. Gross receipts is the total money received from sales. If you received a 1099-K, remember to back out shipping charges and any sales tax eBay collected before treating that number as your gross.
Cost of Goods Sold
COGS is usually the largest deduction. For resellers it’s what you paid for the items you sold, plus inbound shipping and preparation costs. For handmade goods it includes raw materials, direct labor, and production overhead. The mechanics: beginning inventory, plus purchases during the year, minus ending inventory equals COGS.
Inventory tracking is what makes this deduction defensible. If you buy 500 items at thrift stores over the course of a year, you need records showing what you paid for each one. Without those records you can’t substantiate COGS and may end up paying tax on revenue instead of profit.
Operating Expenses
After COGS, ordinary costs of running the operation are deductible:
- eBay platform fees, including listing fees, final value fees, promoted listing costs, and payment processing fees
- Shipping costs, postage, packaging materials, tape, and label printers
- Home office, if part of your home is used exclusively and regularly as your principal place of business. The simplified method allows $5 per square foot up to 300 square feet, for a maximum of $1,500. The standard method uses actual expenses proportional to the space used.6Internal Revenue Service. Simplified Option for Home Office Deduction
- The business-use share of your internet and phone
- Mileage to source inventory, buy supplies, or visit the post office
- Software and subscriptions, including listing tools, inventory management, and accounting software
Self-Employment Tax
If your net profit exceeds $400, you owe self-employment tax on top of income tax.7Office of the Law Revision Counsel. 26 USC 1402 – Definitions The rate is 15.3%, split between 12.4% for Social Security and 2.9% for Medicare, and it applies to 92.35% of your net earnings.8Internal Revenue Service. Topic No. 554, Self-Employment Tax
The Social Security portion only applies to earnings up to the annual wage base, which is $184,500 for 2026.9Social Security Administration. Contribution and Benefit Base Above that, the 2.9% Medicare portion still applies. An additional 0.9% Medicare tax kicks in on self-employment income above $200,000 for single filers or $250,000 for married filing jointly.10Internal Revenue Service. Topic No. 560, Additional Medicare Tax You can deduct half of your self-employment tax as an adjustment to income on Form 1040.
Qualified Business Income Deduction
Sole proprietors filing Schedule C may qualify for the qualified business income deduction under Section 199A, made permanent by the One Big Beautiful Bill Act of 2025. The deduction lets eligible business owners deduct a percentage of their qualified business income from taxable income, whether they itemize or take the standard deduction. It phases out at higher income levels, and thresholds vary by filing status. For most eBay business sellers earning moderate income, this meaningfully reduces the effective tax rate on net profit.
Quarterly Estimated Payments
Business sellers generally need to make quarterly estimated tax payments if they expect to owe $1,000 or more in combined income and self-employment tax for the year.11Internal Revenue Service. Estimated Taxes W-2 employees have taxes withheld from every paycheck; self-employed sellers pay as they go, on their own.
Estimated payments for the 2026 tax year are due April 15, 2026 (for January through March), June 15, 2026 (April and May), September 15, 2026 (June through August), and January 15, 2027 (September through December).12Internal Revenue Service. 13Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty If your income runs seasonal, which is common for eBay sellers around the holidays, the annualized income installment method on Form 2210 lets you base each quarterly payment on actual income earned in that period instead of splitting evenly.
Records to Keep and for How Long
The IRS can audit your return for three years from the filing date under normal circumstances. That extends to six years if you underreported income by more than 25%, and there is no time limit at all on fraudulent or unfiled returns.14Internal Revenue Service. Time IRS Can Assess Tax
Keep records for at least three years, and longer if you want a margin of safety. What matters most:
- Purchase receipts showing what you paid for every item you resell, from thrift store slips to wholesale invoices and online order confirmations
- Sales records. eBay provides transaction history, but download and store your own copies since platforms change data retention policies without warning
- Expense documentation for shipping supplies, mileage logs, home office measurements, and any other deducted cost
- Every 1099-K you receive, along with records showing how you reconciled the gross to your reported income
Digital records are acceptable if they remain legible and accessible. Records trapped in an obsolete format the IRS can’t open are treated as destroyed.
What Happens If You Don’t Report
The most common trigger for penalties on eBay sellers is straightforward: the IRS receives a 1099-K showing $25,000 in gross payments, the seller either doesn’t file or reports significantly less income without explanation, and an automated matching program flags the discrepancy.
Failure to file carries a 5% penalty on the unpaid tax for each month or partial month a return is late, capped at 25%. If a return is more than 60 days late, the minimum penalty is the lesser of $525 or 100% of the tax owed.15Internal Revenue Service. Topic No. 653, IRS Notices and Bills, Penalties and Interest Charges Failure to pay adds 0.5% per month, also capped at 25%. Substantially understating your tax, by the greater of 10% of the correct tax or $5,000 for individuals, adds a 20% accuracy-related penalty on the underpayment.16Internal Revenue Service. Accuracy-Related Penalty
Filing accurately, even when the numbers aren’t pretty, is always cheaper than the penalties for getting caught after the fact.
