Q. What if you earn money from multiple different online surveys, like 400 on one, 300 on another, 200 on another. Do you still need to file if they're under the $400 limit for different companies?
A. Yes. The fact that you have multiple "clients" makes it more likely that the IRS will consider you self employed. Self employment tax is due if your total, from all clients, is more than $432, even if no single client paid you more than $400.
