As the original author of INCOME TAX FUNDAMENTALS, Gene Whittenburg was critical in designing the forms-based approach that has clarified and re-shaped how students have learned income tax fundamentals for three decades. Although co-author and dear friend Gene Whittenburg was unexpectedly lost in March of 2015, this edition continues to uphold his highest standard of publishing excellence and further the insights and advancements that he started in preparing learners to be successful tax preparers years ago.
