My 15yr old son claimed exempt on his w4, do I need to file his income on my taxes? Or do anything with his w2 that he received? He made $1820

You never report a dependent's income from work on your return.  They report work income on their own return, and they must check the box for "I can be claimed as a dependent on someone else's return."  However, your son may not need to file if this was his only income. The FAQ below has a great chart that outlines the federal filing requirements for each filing status and age. The second FAQ gives some great information on whether or not you need to file a State return. Review these FAQ's to make a filing determination:
