People pay taxes for two reasons. On the positive side, most people recognize, even if grudgingly, that payment of tax is a duty of citizenship. On the negative side, they know that the law requires payment, that evasion is a crime, and that willful failure to pay taxes is punishable by fines or imprisonment. The practical questions for tax administration are how to strengthen each of these motives to comply with the law. How much should be spent on enforcement and how should enforcement be organized to promote these objectives and achieve the best results per dollar spent? Over the last few years, the U.S. Congress has restricted spending on tax administration, forcing the Internal Revenue Service to curtail enforcement activities, at the same time, that the number of individual filers has increased, tax rules have become more complex, and more business have become multinational operations. But if too many cases of tax evasion go undetected and unpunished, those who may have grudgingly paid their taxes may soon find it easier to join the scofflaws. These events in combination have created a genuine crisis in tax administration. The chapters in this volume evaluate the capacity of authorities to enforce the tax laws in a modern, global economy and examine the implications of failing to do so. Specific aspects of tax law, including tax shelters, issues relating to small businesses, tax software, role of tax preparers, and the objectives of tax simplification are examined in detail. The volume also builds a conceptual basis for future scholarship, with regard not only to tax administration, but also to such fundamental questions as whether taxpayers respond mostly to economic incentives or are influenced by their experiences with the filing process and what is the proper framework for evaluating the allocation of resources within the IRS.

Why are tax systems so complex? What are the causes of tax law complexity? What are the consequences? Why is tax simplification so difficult to achieve? These, and related questions, lie at the core of this volume on tax simplification featuring chapters by leading tax experts around the world. The quest for simplicity è^' or at least some move towards simplification è^' has been a fixation of governments and others for many years, but little appears to have been achieved. Tax simplification is the most widely quoted but the least widely observed of the usually stated goals of policy (equity and efficiency being the others). It has been used (and abused) as a primary justification for tax reform over the last century, and typically it is seen as è^-a good thingè^-- è^' to say that one is in favour of tax simplification is tantamount to stating that one is in favour of good as opposed to evil.
