Introduction
The levy of taxes is a well-established method for governments to raise the funds necessary to carry out its various programs and initiatives. There are, of course, always vigorous debates about the appropriate level of taxation and the uses to which the taxation proceeds are put, but it is an inescapable truth that governments require some form of taxation revenue to function. One form of taxation that is commonly used is an income tax. Most of us are familiar with the application of personal income tax, as this type of tax is levied on employment and other forms of personal income. Governments also raise funds through assessing income taxes on corporate profits. This practice raises some interesting and complex accounting questions, and it is these questions that will be addressed in this chapter. We will not, however, be examining the processes involved in preparing corporate tax returns or the development of sophisticated tax structures like the one described in the opening vignette, as our focus is on the financial accounting and reporting issues. As well, we will not be looking at other forms of taxation, such as value-added taxes or payroll taxes, as these topics have been discussed in previous chapters.
