Effective tax systems are a critical building block for increased domestic resources in developing countries, essential for sustainable development and for promoting self-reliance, good governance, growth and stability. This report begins with an overview of the current tax capacity building landscape, highlighting key initiatives and recent developments that have emerged in response to developing country needs. It then examines how tax administrations, as well as international and regional organisations, are supporting and delivering capacity building assistance to developing countries, and it offers guidance both in relation to G20 priorities and more generally. The report is based on a mapping exercise and a survey of members of the OECD’s Forum on Tax Administration (FTA), drawing on the insights and expertise of a nine-country task team led by the FTA commissioners of Canada and China and supported by the FTA Secretariat.

This report looks at effective e-service provision by tax administrations, summarising eight critical areas, and explores big data management and portals, as well as natural systems, in detail. It highlights key opportunities in these areas, looking at how these emerging technologies can be best used by tax administrations. It also provides practical examples of how tax administrations have begun to utilise these technologies and delivers a maturity matrix for the two areas to assist strategic and operational decision making by tax administrations. Finally, it sets out conclusions, recommendations and next steps.

This report has been prepared by the Forum on Tax Administration’s E-services and Digital Delivery Programme. The work was initiated by the FTA Bureau as part of its 2015/16 work programme and was led by the Federal Tax Service of Russia (FTS).  With tax administrations clear that e-service options can improve taxpayer compliance levels and participation while at the same time lowering their cost of operation; but with available options many and varied, and with the cost of implementation high,  the FTA has over the last five years provided a wide range of guidance in the deployment of effective e-services.

This report highlights the key opportunities and challenges in establishing, operating, or improving advanced analytics functions in tax administrations. The report provides practical examples of how administrations are currently utilising advanced analytics, and discusses key topics, including organisational arrangements, governance, management and data. The report also discusses how administrations are utilising analytics to improve their operations and deliver better outcomes to taxpayers. Finally, it sets out conclusions, recommendations and next steps. 
This report has been prepared by the Forum on Tax Administration’s Advanced Analytics Programme. The work was initiated by the FTA Bureau following the biennial conference on Advanced Analytics hosted by the Irish Revenue Commissioners in March 2015. That workshop identified member country interest in undertaking work to identify member experience in analytics delivery and share information on both the technologies and tools they were using.

The landscape of tax services, traditionally provided by parties such as tax advisors, accountants and other tax practitioners, is changing, thanks to new technologies and services such as online accounting and filing, mobile devices, and machine-to-machine communication. This may lead to more integrated tax systems, in which taxation is part of the day-to-day operations of SMEs. This report provides an overview of relevant technological and business developments and new service solutions. It also explores how these influence SMEs, tax service providers and tax administrations – and the way that they co-operate. Tax administrations can adopt different types of network strategies for co-operating with tax service providers. The report identifies four basic network strategies. In countries without an established tax service provider infrastructure, such as developing and emerging economies, leveraging new technologies (such as online services and mobile payment) may create new possibilities for providing infrastructure that is both beneficial for SMEs and promotes tax compliance.

This report outlines the essential features of a Tax Control Framework (TCF) and addresses revenue bodies’ expectations of TCFs. It includes a discussion of the issue of materiality, as it is important to understand the relationship between what is material for the purposes of systems of control, such as the external audit of a multinational enterprise’s accounts, and what is material in terms of the tax liabilities arising from that enterprise’s activities in a particular country. It also discusses how revenue bodies could approach the task of testing the soundness of a TCF in any particular case and finally, sets out conclusions, recommendations and next steps.
