The law regarding taxable income hasn’t changed. What has changed is that a $600 annual reporting threshold for banking services has been established.
So let’s say you sold $1000 worth of stuff on Gearswap in tax year 2022, and all the buyers paid you using Paypal. This $1000 will be reported by Paypal to the IRS. When you fill out your 2022 tax return, you need to report all your taxable income, right? That $1000 is not necessarily taxable income. Let’s look at a few scenarios.
1) Scenario 1: Let’s say that $1000 all came from selling used equipment, and you sold all of it for less than the purchase price. In that case, none of the $1000 is taxable income – you took a loss on selling used gear (like most of us do). So you don’t need to report anything on your 1040, because none of this $1000 is taxable income. But if you happen to get audited, it would be really nice to have a spreadsheet showing the original purchase prices and the sale prices for each item, so that you can easily prove that you didn’t have any taxable income as part of that $1000.
Scenario 2: You frequent yard sales and buy things to resell. Let’s imagine that you sold stuff on Gearswap for $1000, and it was all stuff that you bought at yard sales, for a total of $50. In this case, you have $950 of taxable income(1000-50) that you owe capital gains tax on, and your 1040 should reflect that. And again, it is in your best interest to have a record of the transactions that make up that $1000.
3) Scenario 3: You sell $1000 of stuff on ebay; most of it you took a loss on, but you had a Melanzana hoodie in a rare color that went for $500 more than you paid for it. Yes, this is hypothetical. :-) On your 1040, you’ll need to declare that $500 as income and pay capital gains tax on it. The other transactions where you took a loss do not count as taxable income. However – you cannot use those losses to offset the gain on the hoodie, unless you have set up a business. This is an important point. Unless you are operating a business buying and selling, you cannot use capital losses to offset your gains.
Again, this reporting requirement has not changed the taxes you should be paying. What has changed is that banking services must provide more information to the IRS. So if you have a tax liability (i.e. you made money selling stuff for more than you paid for it) you should have been reporting it on your tax return all along.
For my part, I am now maintaining a spreadsheet showing all the items I sell on forums and auction sites, showing what I paid for each item and what it sold for. And for those very few items that sold for more than I paid, I’ll be reporting the profit as taxable income on my 1040.
