Federal Tax 1040EZ is a free Android app developed by RazRon that helps you estimate your refund or amount owed for your federal tax return. The app is easy to use and requires no personal information, so you can enter only dollar amounts. It is important to note that this app does not file your 1040EZ and should only be used for estimation purposes.

This app is perfect for single or joint filers with an income of $80k or less for single filers or $100k or less for married filers. It is specifically designed for those who have income only from W-2s, interest, and unemployment, and no owned property or dependents.
