If you receive money for work, it is taxable. Depending on how much you make, you may or may not be required to file a tax return. But, even if not required, many people benefit financially by filing a tax return. Tax credits for education, deductions, earned income, and over-paying taxes from your paycheck throughout the year could provide a nice refund check once a year. And, in the past there have been stimulus payments from the IRS for several hundred dollars for tax filers. The IRS webpage is a valuable resource and surprisingly easy to navigate. It has everything you need to know, including how to file for free.
