How much money can I make before it affects my financial aid?

Here is a question someone asked about making money:
I’m an incoming freshman this year, and I just got an administrative assistant position at a hospital on Saturdays. I’ll be going to school full-time, but I plan on working through the week during the summer. How much money can I legally make without it affecting my financial aid package? Is there a certain amount of money you can make and not have to file taxes?
