This guide is part of a series of Virtual Training to Advance Revenue Administration (VITARA) reference guides that has been developed based on the contents of the VITARA online modules. This reference guide provides practical advice and tips to ensure tax administration reforms are delivered successfully. The guide reviews tools and methods available in the areas of planning, monitoring, and reporting reform programs and projects, risk management, change control, and resolution of issues. It also elaborates on approaches required to resource the reform program with adequate funds, skilled people, information technology, and other assets, and how to manage different tensions that may arise in the process. The guide also helps tax administrations understand what advance preparations are required for upcoming changes and the support mechanisms that need to be in place for successful change management. The guide ends with a chapter on post-implementation evaluation.
