Do Resellers Have to Pay Taxes? The No-Fluff Guide for Flippers

You scored a great flip, made a profit, and the money is in your account. Now comes the big question: do you have to pay taxes on that? This guide breaks down the essential tax information every reseller needs to know, from understanding your obligations to tracking your costs, all in plain English.

The Short Answer: Yes, You Almost Certainly Owe Taxes

Let's get this out of the way: if you are buying items with the intention of selling them for a profit, the IRS considers that income, and that income is taxable. It doesn’t matter if you sell on eBay, Poshmark, Facebook Marketplace, or at a local flea market. It also doesn't matter if you do it full-time or just as a side hustle to clear out your garage. If your net earnings from self-employment are $400 or more, you are required to file a tax return and pay self-employment taxes.

Many resellers get confused by tax forms, especially the Form 1099-K. They mistakenly believe that if they don't receive one, they don't have to report their income. This is a critical misunderstanding. A 1099-K is simply an informational form that platforms like eBay or PayPal are required to send to you (and the IRS) once you hit a certain threshold. For 2025 and 2026, that federal threshold is generally back to $20,000 in payments AND over 200 transactions. Your legal requirement to report all profit exists from the very first dollar you make, whether a form is generated or not.

Hobby vs. Business: Why the Difference Matters

The IRS makes a key distinction between a hobby and a business, and it all comes down to your intent. Are you selling primarily for personal enjoyment with no real expectation of making a profit, or are you actively trying to be profitable? If you're sourcing inventory, tracking profits, and putting in consistent effort, you're likely running a business. The IRS has several factors it considers, like whether you operate in a businesslike manner (e.g., keep good records) and whether you depend on the income.

Why does this label matter so much? Because the tax treatment is completely different. If your reselling is classified as a business, you report your income and expenses on a Schedule C (Form 1040). This allows you to deduct your business expenses from your income, lowering the amount of profit you're taxed on. If you have a business loss, you may even be able to deduct it against other income.

If it's just a hobby, you still have to report all the income you make. However, as of the Tax Cuts and Jobs Act (TCJA), you can no longer deduct any expenses related to that hobby. This means you pay tax on the full sale price, not just the profit. For anyone serious about reselling, operating as a business is almost always the correct and more financially sound approach.

Your Biggest Tax Shield: Cost of Goods Sold (COGS)

For any reseller, your single most important tax deduction is the Cost of Goods Sold, or COGS. This is the direct cost of acquiring the inventory you sold during the year. It's not just what you paid for an item; it can also include shipping costs to get the item to you. You calculate COGS with a simple formula: (Value of Beginning Inventory + Cost of Purchases) - Value of Ending Inventory = COGS.

Here’s a practical example: You start the year with $2,000 worth of vintage Pyrex in your storage unit (Beginning Inventory). Throughout the year, you spend $10,000 at thrift stores and estate sales on new inventory (Purchases). At the end of the year, you count up your unsold inventory and it's worth $3,000 (Ending Inventory). Your COGS for the year would be ($2,000 + $10,000) - $3,000 = $9,000. That $9,000 is subtracted directly from your gross sales, immediately reducing your taxable profit.

The biggest challenge with COGS is documentation. Those faded thermal receipts from Goodwill are your proof. It's crucial to have a system, whether it's a simple spreadsheet or dedicated software, to log every single inventory purchase. Take photos of receipts as soon as you get them. Without proof of what you paid, the IRS could disallow your deduction, forcing you to pay tax on your revenue instead of your profit.

Don't Miss These Common Reseller Deductions

Beyond COGS, running a reselling business comes with many other deductible expenses that can lower your tax bill. Think of it this way: if you spent money that was "ordinary and necessary" for your business, it's likely deductible. This is where meticulous tracking pays off. Before you list that mid-century modern lamp you found, you might want to know if it's a score or a skip. A quick check with an app like FlipTip AI can give you an instant resale value estimate and profit calculation, helping you make smarter sourcing decisions from the start.

Here are some of the most common deductions for resellers:

* **Platform & Payment Fees:** The fees you pay to eBay, Poshmark, Etsy, Mercari, and others are 100% deductible. This also includes payment processing fees from services like Stripe or PayPal. * **Shipping & Packaging Costs:** Every box, roll of tape, poly mailer, shipping label, and postage cost is a business expense. * **Business Mileage:** The miles you drive to the thrift store, post office, or to meet a buyer are deductible. The IRS sets a standard mileage rate each year (for 2026, it's around 72.5 cents per mile). You must keep a detailed log of your trips, including date, purpose, and mileage. * **Home Office:** If you have a dedicated space in your home used exclusively for your reselling business (for storage, photography, listing, etc.), you can deduct a portion of your rent or mortgage interest, utilities, and insurance. * **Supplies & Software:** This includes office supplies, photography equipment, lighting, and subscriptions to software for bookkeeping (QuickBooks), cross-listing (Vendoo), or inventory management. * **Other Expenses:** Don't forget costs like cell phone and internet bills (the business-use percentage), rent for a storage unit, and fees for professional services like an accountant.

A Quick Word on Sales Tax

Income tax is what you pay on your profits. Sales tax is different—it's a tax on transactions that you collect from the buyer and remit to the state. The rules are complex and vary by state, but there are two key concepts to understand.

First, if you sell primarily on major online marketplaces like Amazon, eBay, or Etsy, you're in luck. Due to "Marketplace Facilitator" laws in most states, the platform is responsible for calculating, collecting, and remitting the sales tax on your behalf. This significantly simplifies things. Second, if you sell directly to customers (e.g., through your own website), you may be required to collect sales tax once your sales into a state exceed a certain threshold, a concept known as "economic nexus." This is often $100,000 in sales or 200 transactions into that state. This area can get complicated fast, so if you have significant direct sales, it's wise to consult a professional.

Getting Started with Tracking (It's Not Too Late!)

If you've been selling for a while without tracking anything, don't panic. The best time to start was when you made your first sale; the second-best time is now. The simplest first step is to open a separate bank account for your reselling activities. Funnel all your sales income into it and make all business-related purchases from it. This instantly separates your business and personal finances, making bookkeeping infinitely easier.

Next, choose a system. It can be a simple spreadsheet you design yourself or a dedicated bookkeeping software like QuickBooks, Wave, or a reseller-specific tool. The key is consistency. Get into the habit of logging every purchase and expense as it happens. Use a scanning app on your phone to save digital copies of every receipt immediately. Good records are not just for tax time; they are the only way to truly know if your business is profitable.
