INSTRUCTOR’S MANUAL
Learning Objectives

1-5. Apply appropriate criteria to evaluate alternate tax systems.
Teaching Suggestions
This chapter provides an overview of why taxes are important, what a tax is, how to calculate a tax,
various tax rates and tax rate structures, different types of federal, state, and local taxes, and how to
evaluate a tax system. One intent of the chapter is to get students thinking about the pervasive influence
of taxes and thus why it is important for a business or accounting student to understand taxes. Discussing
how taxes affect decisions that they will face (buying a house, investing for retirement, etc.) is an
effective way to pique students’ interest.
This chapter also provides an opportunity to motivate students by discussing the political importance of
taxes and the debate over alternative tax systems. Throughout most of the chapter, you can tie the material
discussed back to the debate over alternative tax systems. This is easily done in the section on evaluating
alternative tax systems and alternative tax rate structures but may also be done for other parts of the text.
For example, when discussing how to calculate a tax, you can point out that once the tax base is
computed, it is very easy to calculate virtually any tax. The difficulty is in determining the tax base. The
implication of this understanding is that the tax rate structure (e.g., progressive versus proportional) has
little effect on tax complexity.
In teaching this chapter, the time that you spend in class will vary based on how much discussion that you
want to incorporate regarding evaluating tax systems and implicit taxes. Most of the concepts in this
chapter are relatively straightforward, and thus, the chapter provides students with an introduction to tax
without overwhelming them on the first day or so of class. This is particularly important if your students
