Do Resellers Have to Pay Taxes? A Plain-English Guide for Flippers
Yes, resellers must pay taxes on net profits from their sales, regardless of whether they receive an IRS Form 1099-K. Under federal tax law, net self-employment earnings exceeding $400 require filing an annual return and paying income and self-employment taxes using Schedule C. Selling personal items at a loss is not taxable, but buying items intentionally to resell for profit constitutes taxable business income.
This guide outlines federal tax obligations for resellers, clarifying how tax authorities distinguish casual decluttering from an ongoing flipping business. You will learn how Form 1099-K reporting thresholds operate, which everyday sourcing and shipping expenses offset your revenue, and how to structure your records to avoid overpaying.
Key takeaways
- Net profits over $400 from intentional reselling require reporting on Schedule C, even if you never receive a Form 1099-K.
- Selling personal possessions at a loss is not taxable, but buying items specifically to flip constitutes taxable business activity.
- You are taxed only on net profit; keep strict receipts for Cost of Goods Sold (COGS), platform fees, shipping supplies, and sourcing mileage.
- Flippers anticipating $1,000 or more in annual tax liability should make quarterly estimated payments via Form 1040-ES to prevent underpayment penalties.
Reporting Thresholds and Form 1099-K Realities
Receiving a tax form does not determine whether your resale income is taxable; any net profit earned from flipping is taxable by law from the very first dollar. Many casual flippers mistakenly assume that if an online marketplace does not mail them a Form 1099-K, their earnings remain invisible to the Internal Revenue Service. Under federal law, if your net earnings from self-employment reach or exceed $400 across the tax year, you are legally required to report that income on Schedule C (Form 1040).
Form 1099-K is an informational return sent by third-party settlement organizations such as eBay, Poshmark, Mercari, and PayPal. For federal filing, payment platforms issue this form once you surpass specific statutory volume thresholds, which historically sat at $20,000 in gross payments and 200 separate transactions. Regardless of federal adjustments, several individual states—including Massachusetts, Vermont, Maryland, and Virginia—enforce substantially lower state-level 1099-K reporting limits, often starting at $600.
Crucially, the gross number printed on Box 1a of Form 1099-K reflects total unadjusted payment volume, not your taxable profit. That figure routinely includes buyer-paid sales tax, shipping label charges, refunded orders, and payment processing fees. Treating that top-line number as taxable income will cause you to significantly overpay; you are only taxed on what remains after subtracting allowable business deductions and inventory costs.
Hobby vs. Business: How the IRS Evaluates Your Activity
The IRS separates a business from a hobby based primarily on whether an activity is conducted with the genuine objective of making a profit. If you clean out your personal closet and sell an old winter parka on eBay for $80 that you originally bought for $220, you have sustained a nondeductible personal loss. You do not owe income tax on that transaction because your proceeds were lower than your original purchase price.
Flipping crosses into business territory the moment you buy goods with the specific expectation of selling them for more than you paid. The IRS relies on a nine-factor framework outlined in Treasury Regulation Section 1.183-2 to determine your status. Key indicators include whether you carry out the activity in a businesslike manner, maintain accurate bookkeeping, depend on the income, adjust strategies to improve profitability, and have generated a net profit in at least three of the last five consecutive years.
Operating as a recognized business provides substantial tax advantages over hobby status. Following tax code changes under the Tax Cuts and Jobs Act, individual taxpayers can no longer claim miscellaneous itemized deductions for hobby expenses. That means if the IRS classifies your reselling as a hobby, you must report the gross receipts as taxable income without deducting operational overhead like mileage, shipping supplies, or listing subscriptions. Operating as a legitimate trade or business on Schedule C preserves your right to deduct all ordinary and necessary operational expenses.
Tracking Cost of Goods Sold and Everyday Deductions
Your tax bill is calculated from net profit, which is your gross revenue minus your Cost of Goods Sold (COGS) and ordinary operational expenditures. Cost of Goods Sold represents the purchase price of the specific inventory items that sold during that calendar year. If you buy a vintage stereo receiver at an estate sale for $35, replace an internal belt for $10, and sell it for $210, your direct cost basis for that piece of inventory is $45.
Beyond inventory costs, ordinary operating expenses reduce your taxable net income dollar for dollar. Allowable Schedule C deductions include platform final value fees (typically 12% to 15% on eBay or 20% on Poshmark), payment processing charges, postage, thermal label rolls, cardboard mailers, bubble wrap, poly bags, and cleaning supplies. Resellers can also deduct the business percentage of home office space used exclusively for inventory storage, cell phone bills used for sourcing, mileage traveled between thrift stores at the standard federal mileage rate, and essential software.
Maintaining strong profitability requires precise sourcing math before an item ever enters your inventory ledger. Resellers frequently use tools like FlipTip AI, a phone app where you point the camera at any item and see what it actually sold for (identified from every label, logo and model number). Rather than relying on speculative asking prices, FlipTip displays real completed sales with dates—covering eBay, as well as Mercari and Poshmark in the US on its paid plan, while estimating from current local listings in other regions—alongside your expected profit, the most you should pay, a sell-speed score, and an immediate buy-or-skip verdict. Knowing exact margins and fees upfront makes expense tracking clean from day one.
Sales Tax vs. Income Tax and Resale Certificates
Income tax and sales tax are two completely distinct obligations that every flipper must differentiate. Income tax is paid by you to federal, state, and local governments based on the net profits your business earns over the year. Sales tax, by contrast, is a consumption tax paid by the end customer on retail purchases and collected by the seller on behalf of state tax agencies.
For online sellers, Marketplace Facilitator Laws have drastically simplified sales tax compliance. Major platforms—including eBay, Poshmark, Mercari, and Etsy—are classified by law as marketplace facilitators across virtually every US state with a sales tax. The platforms automatically calculate, collect, and remit sales tax directly to the buyer's home state at checkout. If you sell exclusively through these facilitated channels, you generally do not need to register to collect retail sales tax on those specific transactions, though you may still have state reporting requirements.
Where sales tax directly impacts your bottom line is at the sourcing stage. When you buy merchandise intended exclusively for resale, you should not be paying sales tax to thrift stores, estate sales, or liquidators. By registering your business with your state department of revenue, you can acquire a Resale Certificate (also called a seller's permit or resale license). Presenting this document to suppliers exempts your inventory purchases from sales tax, saving an immediate 5% to 10% on your upfront acquisition costs.
Estimated Quarterly Taxes and Clean Recordkeeping
When you work as a W-2 employee, an employer withholds income and FICA taxes from every paycheck. When you flip items as a sole proprietor, no entity withholds taxes on your behalf. If you expect to owe $1,000 or more in federal taxes for the calendar year after subtracting withholdings and refundable credits, the IRS requires you to pay estimated taxes quarterly using Form 1040-ES.
Estimated tax payments are divided into four installments due across the year: April 15, June 15, September 15, and January 15 of the following year. In addition to regular federal and state income tax brackets, self-employed flippers owe self-employment tax (covering Social Security and Medicare), which sits at 15.3% on the first 92.35% of your net Schedule C earnings. A standard rule of thumb is to set aside 25% to 30% of your net profits into a separate high-yield business savings account every time you reconcile your books.
Avoiding tax audits and penalties comes down to clean recordkeeping habits. Open a dedicated business checking account and credit card; running inventory purchases, packing tape, and postage through personal accounts creates an administrative nightmare during tax preparation. Retain itemized physical receipts or digital photos showing source, date, and unit cost for all inventory. Keep a simple spreadsheet or accounting software tracking sourcing price, listing date, sold date, platform fees, and gross payout.
Remember that tax laws differ across states, jurisdictions, and business structures. This overview provides general operational principles, so consult a licensed Certified Public Accountant (CPA) or Enrolled Agent (EA) to evaluate your specific tax situation. Before you spend working capital on unverified inventory, scan it with FlipTip to confirm real completed comps, establish your maximum buy price, and ensure every flip protects your margins.

Do I have to pay taxes if I didn't receive a 1099-K from eBay or Poshmark?
Yes. The IRS requires you to report all taxable net profit earned from self-employment over $400, regardless of whether a platform meets the transaction threshold to issue a Form 1099-K.
Can I deduct the cost of items I bought at garage sales without receipts?
Yes, but you must keep a contemporaneous written log. Record the purchase date, neighborhood or sale address, specific item description, and cash amount paid to substantiate your Cost of Goods Sold during an audit.
What happens if my reselling business operates at a financial loss?
If your activity qualifies as a legitimate business under IRS rules, you can report that net loss on Schedule C to offset other taxable income on your Form 1040. However, continuous multi-year losses may cause the IRS to reclassify your operation as a hobby.
Do I need an LLC to file taxes as a reseller?
No, an LLC is not required. By default, the IRS treats individual resellers as sole proprietors, allowing you to report your business income and deductions directly on Schedule C of your personal tax return using your Social Security number.
