Workshop on Board Governance of Revenue Authorities, Mauritius, 14 to 16 April 2014

Presentations delivered during this Workshop are now available for download from the Members area.

The Workshop examined the various models of Board Governance structures in terms of their constitutions (the selection and composition of their membership), their mandates, the relationships with the CEO (Commissioner Generals/Director Generals) and the Ministry responsible. Country experiences on the various aspects of the Board mandate within Revenue Authorities (RAs) were shared by Mauritius, Malaysia, Canada, Kenya and Swaziland.

Recent years have witnessed many revenue administrations adopting elements of autonomy through the establishment of Revenue Authorities. These Revenue Authorities have adopted corporate governance structures with oversight Boards of Directors responsible for a wide array of key policy issues such as financial management, human resource issues and general organizational arrangements. However, there still exists wide variations from country to country on the responsibilities of these Boards and also on the level of autonomy enjoyed by their respective RAs.

New E-learning Product Now Available


CATA and the Canada Revenue Agency (CRA) are pleased to announce the introduction of a new E-learning product – Tax Audit Fundamentals (TAF), for use by CATA members.

TAF is an interactive learning experience designed to take new auditors through each stage of conducting an audit. It may be completed entirely online, or alternatively downloaded in PDF format for offline use. An exercise is presented at the conclusion of each unit of TAF to reinforce the learning objectives. There is also a final exercise at the end of the product to enable the learner to check the level of comprehension of basic auditing attained. We encourage all users to provide feedback about TAF to the CRA through the questionnaire included as part of the product. The CRA will monitor user feedback on an ongoing basis.

To access TAF please log in to the members area and select "e-learning: Tax Audit Fundamentals".
