Welcome to Jeff Bogart's Toolbox
The following tools are designed to be helpful to AARP Tax-Aide Counselors and Trainers. They are not intended to replace official IRS documentation and while accuracy is attempted, no software can be guaranteed to be bug-free. If you see a problem, please let me know so that it can be corrected.

Most of the calculators have a year option that allows the selection of the current and three years prior. Version changes can be seen by viewing the web page source if desired.
