The new U.S. rule will probably cause a lot of additional 1099s to be issued for 2022 transactions for PayPal, Venmo, eBay, etc. transactions, all third party payers, regardless of whether they are business revenue or personal repayments. My understanding is that Venmo’s efforts to identify business income (and charge a fee for it) are in the early stages, vague and murky.
The 1099-K is an informational report that goes to you and the IRS. You do not have to report anything that is not income on your tax return, but be aware the IRS has this information, and, in the rare event you are audited, best to have some sort of documentation that demonstrates what is and isn’t business income.
A lot of folks doing pandemic clean out by selling household items on eBay were surprised and concerned to get 1099s. Typically in that case one is selling at a loss because the items have depreciated in value, and you get used prices for them, so not a business, and there is no income to declare. Conversely, no you cannot claim a business “loss” for those transactions unless you are actually in business as a reseller. See IRS publications for determining what criteria make your activities a business.
Not to panic if you haven’t kept the original receipt for the kitchen gadgets you sold on eBay,
but best to maintain some documentation identifying the items. You can request selling history by going into your account settings under Personal Information and scroll to the bottom. Under My eBay Data, you can request sold history up to two years back.
All income must be declared, including of course cash payments from your direct bookings, and all tax evasion (as opposed to legal tax avoidance), is wrong. Unfortunately, it’s much easier for the IRS to catch the “little guy” at tax cheating than, say, a bad actor real estate investor, due to the nature of the information that the IRS receives. The IRS gets W2s and 1099s from third parties for working stiffs. There is a relatively high level of scrutiny of the earned income and child care tax credits.
But if you are a bad actor in the real estate business, valuations for your sales and losses will be based on your bookkeeping, ostensibly backed by legit appraisals. You can set up additional companies to provide services and goods for your properties that are charged to expense, ostensibly at market rates. It is resource-intensive for the IRS to challenge those valuations and expense rates.
