Selling personal items online: when you owe taxes and when you don't (2026)
Reviewed by Vincent Wesley Couey, CeoCult Editorial Team
You cleaned out your closet, sold an old laptop on Facebook Marketplace, and maybe got a 1099-K from the platform. Now you're wondering if you owe the IRS money. In most cases, you don't, selling personal items for less than you paid is not taxable income. But you need to know how to prove it, how to report it if you got a 1099-K, and where the line is between casual selling and running a business.

The basic rule: sold at a loss = no tax
When you sell a personal item for less than you originally paid, you have a loss, and losses on personal property are not taxable and not reportable. This covers the vast majority of casual selling situations:
- Selling a used phone for 00 that you bought for 00, no tax
- Selling used furniture for 50 that cost 00 new, no tax
- Selling kids' clothes for 0 that cost 00, no tax
- Selling a used TV for 00 that cost 00, no tax
The IRS Form 1099-K guidance confirms that personal items sold at a loss generate no reportable income. Most used items lose value, which means most personal sales are not taxable.
When personal item sales ARE taxable
You owe tax when you sell a personal item for more than you originally paid. This is a capital gain on personal property. Common examples:
- Sneakers bought for 50 that you sell for 00, taxable on the 50 gain
- A vintage record bought at a yard sale for , sold for 00, taxable on the 95 gain
- Jewelry inherited (your cost basis is the fair market value at the time of inheritance) sold for more than that value, taxable on the gain
Gains on personal items held for more than one year are taxed at long-term capital gains rates (0%, 15%, or 20%) depending on your income. Items held for one year or less are taxed as ordinary income.
What to do if you got a 1099-K for personal sales
If a platform sent you a 1099-K that includes personal item sales, the IRS has a copy. You must report the income, but you also show your cost basis to demonstrate there's no taxable gain.
Option 1: Report on Schedule C (if mixed with business sales)
If your 1099-K includes both business sales and personal items, report the full gross on Schedule C Line 1. Then deduct your business COGS and expenses normally. For the personal items, include their original cost as part of your COGS or as "returns and allowances" on Line 2 to offset the gross amount.
Option 2: Report on Schedule 1 and Schedule D (personal only)
If you only sold personal items (no business activity), report the gross amount on Schedule 1 as "other income" and then show an offsetting adjustment for the cost basis. For items sold at a gain, report on Schedule D as a capital gain.
Option 3: Use Part II of Schedule 1 (simplest for losses)
Report the 1099-K amount as income on Schedule 1, Line 8z with a description like "1099-K personal item sales, sold at loss." Then enter an equal offsetting amount as a negative adjustment. Net result: /bin/sh taxable income. This "zeros out" the 1099-K for the IRS.

Where casual selling becomes a business
The IRS draws a line between occasionally selling personal belongings and operating a resale business. There's no magic number of sales that triggers business classification, it's about intent and pattern:
| Casual / personal selling | Business / reselling |
|---|---|
| Selling your own used belongings | Buying items specifically to resell for profit |
| Occasional, irregular sales | Regular, consistent selling activity |
| No inventory sourcing trips | Sourcing at thrift stores, estate sales, wholesale |
| Items you owned and used personally | Items you never intended to keep |
| Report on Schedule 1 / Schedule D | Report on Schedule C (business income) |
If you're reading this guide because you sell regularly and are wondering about your taxes, you're probably running a business. And that's actually good news, because businesses can deduct all their expenses. See our hobby vs. business guide for the full IRS test.
Don't ignore a 1099-K, even for personal sales
The IRS's automated matching system will flag any 1099-K that doesn't appear on your tax return. If you ignore it, you'll receive a CP2000 notice proposing tax on the full amount, even if you owe nothing. Always report and offset. See our complete 1099-K guide for the full reporting walkthrough.
If your personal reselling has grown into something that looks more like a business, it may be worth exploring Sellerboard or similar tools to track your cost basis and profits automatically, and to determine whether operating as an official business makes sense for your tax situation.
