If you are self-employed, you are required to keep accurate business records of all your income and expenses and report it on your tax return even if you do not get any paperwork.
A 1099-K form is not issued by individual clients. The 1099-K would be issued to you by payment processors, such as square or Venmo or eBay, if they pay pass through a certain amount of money to you, and the threshold is much higher than $600. (i’m too lazy to look it up right now.) If another business hires you, they are required to issue a 1099 – MISC if they pay you more than $600 in a year. Individual clients who are not businesses, who simply hire you to do a job, are not required to give you any tax paperwork. That is why you are required to keep your own business records.
