I'm a little confused here, so I will try to clarify my confusion
You didn't make any money and you're wondering if you have to file your taxes?
Well if you get a job, most (short of cash-paying services) will give you a W-4 to sign, if you don't, you will get the maximum taken out of the amount you make. If you didn't work, then what taxes are you trying to pay? (Unless you like the US government that much that you are giving them your money...in which case, I like them tooo, so sending money to me is like sending it to uncle sam)
If you mean you have to file the forms before April 15, then that really isn't paying your taxes. What that really is, is you comparing what you got taxed to what you should be taxed. If you didnt fill a W-4, this is where you get to fix the problem. If you overpaid, either erroneously, or because you had lots of deductions that decreased the amount you should be taxed, then you send the correction before April 15 to the government and they send you a check. If you pay too little in taxes before hand, then you send a check to the government before they do an audit and make you pax interest.
Ofcourse, if you did gain income that could not be easily taxed, aka capital gain (money from stock investmest, real estate, etc), you get paid in cash or tips, or any extra, then you will have to fill out the form and pay your taxes then or they will come after you like someone in the news right now.
But most likely, if you work a job somewhere, where a contract was filled with a company with a fein (federal employer identification number), Uncle Sam is already taking his tax from you before you sit down to enjoy that money.
Hope this clarifies all confusion everywhere, but from me as to what your question is, and your confusion.
