OpenTaxSolver (OTS) is a free, safe + secure program for calculating Tax Form entries for Federal and State personal income taxes. It automatically fills-out and prints your forms.

The project is regularly updated with new tax forms, regulations and updates.

The OpenTaxSolver (OTS) is created by Aston Roberts, several years ago who are still updating the app regularly.

The OTS tax package is intended to be used with the Tax booklets published by your government for determining what numbers you need to enter, and then it assists you in doing the otherwise tedious calculations while showing the intermediate and final numbers. It takes care of the tedious and error-prone work.
OTS is intended for those who are comfortable doing their own taxes - especially those who have previously done their taxes and basically understand how to fill out the forms. OTS does much of the math for you.
