Applications in information technology have come to the fore as the major strategies used by both tax agencies and businesses to meet the challenges brought on by the increasing speed, complexity, and global scope of economic transactions. With these applications countries can administer existing taxes better, and also change both the administration and the structure of taxes to better achieve developmental objectives. Techniques for developing tax forecasting and tax simulation models are now sufficiently advanced that even unsophisticated tax departments can use such models to offer new services, enforce compliance, and identify tax evasion schemes.
