All citizens or residents of the United States and residents of Puerto Rico that are wage earners are required to file a federal tax return if they exceed income limits set by law. If you have little income and you qualify for a refund based on the earned income credit, you must file to get it even if you don't owe any taxes. Dependent children who earn wages must also file a tax return. If the dependent child cannot file for any reason, a parent, guardian, or legally responsible adult must file for the child. Resident aliens must also file a tax return and are subject to the same rules that apply to U.S. citizens. These tips are provided to give you general information about your taxes.
