Policymakers and program managers are continually seeking ways to improve accountability in achieving an entity's mission. A key factor in improving accountability in achieving an entity's mission is to implement an effective internal control system. An effective internal control system helps an entity adapt to shifting environments, evolving demands, changing risks, and new priorities. As programs change and entities strive to improve operational processes and implement new technology, management continually evaluates its internal control system so that it is effective and updated when necessary. Section 3512 (c) and (d) of Title 31 of the United States Code (commonly known as the Federal Managers' Financial Integrity Act (FMFIA)) requires the Comptroller General to issue standards for internal control in the federal government.

Teacher Professional Learning in an Age of Compliance: Mind the Gap examines ways in which practice-based inquiry in educational settings, in a number of different countries and contexts, can transcend current ways of working and thinking such that authentic professional learning is the result. The authors contend that education policy, under pressure from a number of quarters, is retreating into a standardized, audited, and backward-looking arena, with the advances of more progressive educational philosophy being rolled back. In an age where practitioner inquiry and action research have often been ‘hijacked’ for the purposes of broad-based policy implementation, this book offers a rationale for reclaiming the critical edge so fundamental to inquiry-based professional learning. It examines the potential of inquiry-based forms of teacher professional learning to contribute to the growth of professional knowledge for and about teachers’ work. The authors intend that the book will assist in building new forms of professional knowledge that go beyond the current compliance model – engineered from less enduring materials – to inform a new model with its foundations in a strong ethical and moral framework. They also believe that this new model, if implemented, will help to reverse today’s conservative educational trends and make teacher professional development a force for genuine progress once again. They have consciously moved away from the celebratory tone of much of the academic reporting of teacher professional learning, adopting instead a genuinely critical edge. In covering a wide range of policies and practices from across the international spectrum, they have allowed themselves the freedom to engage in serious epistemological arguments about the nature of professional knowledge, as well as how it is constructed and employed.

The IMFs Revenue Administration Gap Analysis Program (RA-GAP) assists revenue administrations from IMF member countries in monitoring taxpayer compliance through tax gap analysis. The RA-GAP methodology for estimating the VAT gap presented in this Technical Note has some distinct advantages over commonly used methodologies. By using a value-added approach to estimating potential VAT revenues, as compared to the more traditional final consumption approach used by most countries undertaking VAT gap estimation, the RA-GAP methodology can provide VAT compliance gap estimates on a sector-by-sector basis, which assists revenue administrations to better target compliance efforts to close the gap. In addition, the RA-GAP methodology uses a unique measurement for actual VAT revenues, which isolates changes in revenue performance that might be due to cash management (e.g. delays in refunds) from those due to actual changes in taxpayer compliance.

The IMF Fiscal Affairs Department’s Revenue Administration Gap Analysis Program (RA-GAP) assists revenue administrations from IMF member countries in monitoring taxpayer compliance through tax gap analysis. The RA-GAP analytical framework for estimating excise gaps presented in this Technical Note sets out the steps and data required for comprehensive top-down gap estimates based on a comparison of actual collections to potential collections, which is estimated from consumption (or use) and expenditure of excise commodities. The note outlines the motivation for, and different approaches to, excise gap estimation; and identifies the design criteria for robust gap estimates. The note was jointly produced by RA-GAP team and the Slovak Republic’s Institute for Financial Policy, piloting the framework for the mineral oils excise gap in Slovakia.

This technical note describes bottom-up CIT gap estimation techniques applied by revenue administrations in the following highly experienced countries in this approach: Australia, Brazil, Canada, Denmark, Sweden, the United Kingdom, and the United States. The main topics included in the descriptions are techniques applied, CIT gap results, advantages and disadvantages of different available options, and future developments and recommendations for any revenue administration interested in starting bottom-up CIT gap estimation programs having no prior experience.

This Technical Assistance Report presents the estimates of tax gaps for general sales tax (GST) and corporate income tax in Costa Rica. The estimated GST compliance gap in Costa Rica increased from 29 percent in 2012 to 31 percent in 2016. The compliance gap in 2016 was equivalent to 1.9 percent of GDP. The estimated compliance gap is higher than the average value-added tax compliance gaps of European countries and Latin American countries. Large GST compliance gaps relative to GDP are observed in manufacturing, trade, and hotels and restaurants. The estimated GST policy gaps were at about 4 percent of GDP from 2012 to 2016. Most of the GST policy gap consists of the GST expenditure gap, showing the effects of policy choices.

It is generally difficult to measure revenue not collected due to noncompliance, but a growing number of countries now regularly produce and publish estimated revenue losses. Good tax gap analysis enables the detection of changes in taxpayer behavior by consistent estimates over time. This Technical Note sets out the theoretical concepts for personal income tax (PIT) gap estimation, the different measurement approaches available, and their implications for the scope and presentation of statistics. The note also focuses on the practical steps for measuring the PIT gap by establishing a random audit program to collect data, and how to scale findings from the sample to the population.
