Corruption, Complexity and Tax Evasion

Abstract

Tax evasion is facilitated by corruption, and corruption is facilitated by tax complexity. This article argues and presents evidence that tax systems have become far more complex than they need to be. The growth of public sector operations over the past century was accompanied by higher and more complex taxes, higher public spending, many new government programs, and an increasing involvement by governments in the functioning of the countries’ economies and in the activities of citizens. It has created a great deal of complexity in public sectors, and a fertile field for corruption, tax evasion or tax avoidance, and abuses in some government programs. The more governments relied on tax systems to pursue an increasing number of social and economic objectives, the more complex the tax systems became and the greater were the opportunities created for some taxpayers to get around the system. Complexity also encourages the growing army of lobbyists to push for small tax changes advantageous to their clients, causing tax systems to become increasingly more complex. In addition, it increases the costs of administering tax systems and of complying with the many tax obligations. To what extent tax systems have become fertile for corruption and tax evasion is likely to depend on cultural characteristics of countries among other factors. Globalization has opened new doors and new opportunities for individuals and corporations who operate, or can operate, globally to exploit the new tax-avoiding possibilities created by globalization and a global financial system. Nevertheless, complexity is not inevitable. It could, however, be reduced, as the experience of some countries has shown.
