Tax Law - NTTC Workbook
The NTTC Workbook includes 15 sample problems (effectively replacing IRS Pub. 4491-W). It also has numerous comprehensive quiz/discussion questions. It covers ONLY Federal Tax Law topics. Answers to the problems are available from your state Training Specialist (TRS) and are not posted online.
The NTTC Workbook is delivered as three separate .pdf files (plus a fourth document with corrections and clarifying notes).
