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