Is there any tax form to fill out if I didn't make enough money to file taxes this year? Will the IRS know my income wasn't enough to file if they don't get a return?

Chances are good that The IRS has your income tax documents including your W-2.

Assuming you did not earn enough to file, you need not be concerned or fill out a tax form.
