This publication contains the official text of the Multilateral Convention on Mutual Assistance in Tax Matters as amended by the 2010 Protocol. The original Convention was developed jointly by the Council of Europe and the OECD and opened for signature by the member states of both organisations on 25 January 1988. The original Convention was amended in 2010 to align it to the international standard on information exchange for tax purposes and to open it to all countries, responding to the call of the G20 to make it easier for all countries to secure the benefits of the new co-operative tax environment. The amended Convention entered into force on 1 June 2011.
This Convention aims to help governments enforce their tax laws, provides an international legal framework for co-operation among countries in countering international tax avoidance and evasion. It offers a variety of tools for administrative co-operation in tax matters, providing all forms of exchange of information, assistance in tax collection and service of documents. It also facilitates joint audits and information sharing to counter other serious crimes (e.g. money laundering, corruption) when certain conditions are met. It preserves the rights of taxpayers, provides extensive safeguards to protect the confidentiality of the information exchanged, in particular in relation to personal data. The operation of this self-standing multilateral convention is overseen by a Co-ordinating Body comprised of the Parties to the Convention.
This report aims at assisting tax authorities in designing and implementing an effective Value Added Tax/Goods and Services Tax (VAT/GST) policy response to the growth of the sharing and gig economy. The rise of this phenomenon, powered by digital platforms, has transformed a number of industries within just a few short years. It involves large numbers of new economic operators (often private individuals), who monetise (often) underutilised goods and services by offering these, via digital platforms, for temporary (“shared”) use by primarily private consumers. Questions have been raised whether existing VAT/GST policy and administration frameworks are sufficiently capable of dealing with this new economic reality notably with a view to protecting VAT/GST revenue and minimising economic distortions. This report sets out the core components of a comprehensive VAT/GST policy strategy for tax authorities to consider in response. It analyses the key features of the sharing and gig economy and its main business models; identifies the associated VAT/GST challenges and opportunities; and presents a wide range of possible measures and approaches to support an effective policy response. This includes detailed guidance on the possible role of digital platforms in facilitating and enhancing VAT/GST compliance in the sharing and gig economy.
The report examines the distributional effects of value-added tax (VAT) and excise tax systems in 20 OECD countries, and investigates the effectiveness of reduced VAT rates as a redistributional tool.
Outdoor air pollution kills more than 3 million people across the world every year, and causes health problems from asthma to heart disease for many more. This is costing societies very large amounts in terms of the value of lives lost and ill health. Based on extensive new epidemiological evidence since the 2010 Global Burden of Disease study, and OECD estimates of the Value of Statistical Life, this report provides evidence on the health impacts from air pollution and the related economic costs.
This Convention offers tax authorities a legal framework for co-operating across borders without violating the sovereignty of other countries or the rights of taxpayers. Includes the text of the convention and commentaries. The Convention entered into force in 1995, and interest is growing, with almost half of the countries that have signed the Convention doing so in the last five years. This reflects the growing importance of exchange of information and other forms of co-operation between tax administrations in an increasingly borderless business and financial world. ThisTwentieth Anniversary edition includes the text of the convention as well as commentaries.
The report sets out how tax compliance strategies are evolving in light of new technologies, data sources and tools, including the increasing use of advanced analytics. It also looks at how these changes might affect the role of audit and auditors in the future. Finally it suggests a number of areas where further work by the Forum on Tax Administration might assist tax administrations in their consideration and implementation of administrative reforms as a result of the changing compliance environment.
The application of tax treaties to cases involving partnerships raises a number of complex issues. When is a partnership entitled to the benefits of a tax convention? What happens when the residence and source States apply different articles of the Convention on the basis of differences in their domestic law? How can the problems arising from conflicts of income allocation be solved? This report addresses these issues in detail and focuses on specific factual examples. For each example, the facts and, where applicable, relevant aspects of domestic tax laws are described. Comprehensive recommendations for dealing with the international taxation of partnerships in practice are also presented.
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.
Taxing Working Families provides insights into how income taxes and social security contributions affect the distribution of income between different types of families in OECD countries. Certain generally available cash benefits for families – regarded as negative taxes – are also taken into account.
The study concentrates on the effects of these taxes on the distribution of income between different types of working households, looking at three dimensions of inequality: vertical inequality between households at different income levels, horizontal inequality between households with different numbers of children and the tax treatment of one-earner versus two-earner households.
This new high profile report provides details of taxes paid on wages in twenty economies in Latin America and the Caribbean. It covers: personal income taxes and social security contributions paid by employees; social security contributions and payroll taxes paid by employers; cash benefits received by in-work families.
It illustrates how these taxes and benefits are calculated in each member country and examines how they impact on household incomes. The results also enable quantitative cross-country comparisons of labour cost levels and the overall tax and benefit position of single persons and families on different levels of earnings.
The publication shows the amounts of taxes and social security contributions levied and cash benefits received for eight different family types which vary by a combination of household composition and household type. It also presents the resulting average and marginal tax rates (i.e. the tax burden). Average tax rates show that part of gross wage earnings or total labour costs which is taken in tax and social security contributions (both before and after cash benefits). Marginal tax rates show the part of a small increase of gross earnings or total labour costs that is paid in these levies.
The data presented can be used in academic research and to analyse tax, social and economic policies in Latin America and the Caribbean.
