1099-K: back to $20,000 and more than 200 transactions
The One, Big, Beautiful Bill retroactively restored the pre-2021 rule: payment apps and marketplaces must send a 1099-K only if your payments for goods or services total over $20,000 in more than 200 transactions. They may still send one for less, and the IRS says you must report all income either way. General information, not tax advice: check with a tax pro.
