1099 Misc. Vs. Earned Income SSI. You're retired, receiving Social Security Income (SSI), and suddenly you receive a 1099 MISC tax form in the mail with your name on it showing an amount of money paid to you. Is this form going to automatically invalidate your current SSI benefits? How does it get treated under earned income limitations? Will you be penalized? These are all good questions for a retiree in the above situation to ask. Fortunately, the information is readily available.
