Federal Income Tax Calculator

This calculator is a PHP University Project.

It took me 3 hours and 40 minutes to create this calculator. You can watch it being made, time lapsed to just over 7 minutes. It's pretty cool ;-)

NOTE: This U.S. Federal Individual income tax calculator shows the estimated personal taxes owed by both individuals and married couples, whether employeed or self-employeed.

The 2013 income tax calculations are what the law currently specifies will be owed by Americans in the year 2013, unless Congress (beleaguered by the debt ceilling, a Presidential election, and massive looming automatic budget cuts) has the time and wherewithal to change the law.
