Poshmark and Mercari Reseller Taxes: Closet Cleanout or Business?
The same 1099-K can mean you owe nothing or quite a bit, depending on whether you are selling your own things at a loss or flipping inventory for profit. Here is how to tell and how to report each.
Selling on Poshmark or Mercari can be cleaning out your closet, or it can be a real reselling business, and the taxes are wildly different depending on which one it is. The same 1099-K can mean you owe nothing or owe quite a bit. Here is how to tell, and what to do about it.
Cleaning out your closet versus running a business
If you are selling your own used things, you are usually selling them for less than you paid, which is a personal loss, not income. If you are buying inventory to flip for a profit, that is a business, and the profit is taxable. The IRS cares about your intent and pattern, not the app you use.
The 1099-K you might get
Marketplaces issue a 1099-K once you pass the federal threshold, currently more than 20,000 dollars and more than 200 transactions, though several states set lower bars. A 1099-K is not a tax bill. It reports gross sales, and it is on you to show how much of that, if any, is actually taxable profit.
How to report personal items sold at a loss
This is the part casual sellers miss. If you get a 1099-K for selling personal items at a loss, you cannot just ignore the form, but you also do not owe tax. The IRS has you report the gross amount on Schedule 1, line 8z, then back it out with an equal offsetting entry on line 24z, so the net is zero. The loss itself is personal and not deductible, but the paper trail keeps the IRS matching system happy.
If it is a business: inventory and COGS
Buy to resell and you are running a business on a Schedule C. Your profit is sales minus your cost of goods sold, which means tracking what you paid for each item, your cost basis. Marketplace fees, shipping you cover, and supplies are deductible expenses on top of COGS. If it is somewhere in between, the hobby vs business rules decide your fate.
Know your numbers before the 1099-K shows up
A 1099-K reports gross sales, not profit. Track your cost basis and fees so you only pay tax on what you actually made.
