  Our Mission

Our mission is to help as many taxpayers as we can get fast, easy to understand, accurate, and bug free tax information.


  Our History

This website began by hiring computer programmers to build a penalty & interest tool on a tax attorney's website. The tool quickly gained in popularity and eventually was spun off to its own website. With the help of our users, we have continually improved the accuracy of the tools on this website.


  Our Current Status

At the moment we have eight calculators. We have the penalty and interest calculator, an IRS interest calculator, an overpayment interest calculator, a tax calculator, an International tax calculator, a deposit penalty calculator, a sales tax calculator, and an estimated tax penalty calculator.


  Recent Changes

We have recently added hardware, simplified the calculators, reduced javascript and php errors, and improved structures underneath the calculators.

Our most recent addition is the estimated tax penalty calculator, that we are continuing to work on so that it becomes of the highest quality


  Future Plans

We are presently working on building new tools, while continuing to support and update our previous calculators. We have future plans to build a PFIC calculator, a state penalty and interest calculator, and a tax professional directory.


  How You Can Help

We are always looking for ways to improve our calculators so that we can improve tax knowledge and understanding. If you would like to see something built, please let us know. If you have any questions or suggestions on how to enhance any of our calculators, please feel free to contact us at
