Consumption Tax Trends provides information on Value Added Taxes/Goods and Services Taxes (VAT/GST) and excise duty rates in OECD member countries. It also contains information about international aspects of VAT/GST developments and the efficiency of this tax. It describes a range of other consumption taxation provisions on tobacco, alcoholic beverages, motor vehicles and aviation fuels.

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.

This paper reassesses the often-made conclusion that the VAT is regressive, drawing on tax microsimulation models constructed for an unprecedented 27 OECD countries. The paper first assesses the competing methodological approaches used in previous distributional studies, highlighting the distorting impact of savings patterns on cross-sectional analysis when VAT burdens are measured relative to income. As argued by IFS (2011), measuring VAT burdens relative to expenditure – thereby removing the influence of savings – is likely to provide a more meaningful picture of the distributional impact of the VAT. On this basis, the VAT is found to be either roughly proportional or slightly progressive in most of the 27 OECD countries examined. Nevertheless, results for a small number of countries highlight that broad-based VAT systems that have few reduced VAT rates or exemptions can produce a small degree of regressivity. Results also show that even a roughly proportional VAT can still have significant equity implications for the poor – potentially pushing some households into poverty. This emphasises the importance of ensuring the progressivity of the tax-benefit system as a whole in order to compensate poor households for the loss in purchasing power from paying VAT. In the broader context of the COVID-19 crisis, the findings of the paper suggest there may be scope in many countries for VAT reform to help address revenue needs, as this revenue may be generated with less significant distributional effects than previously thought. While standard VAT rates are high in many countries, OECD evidence shows that scope exists to broaden VAT bases. Nevertheless, any VAT increases, including VAT base broadening measures that impact the poor, should be accompanied by compensation measures for poorer households, such as targeted tax credits or benefit payments.

This paper decomposes consumption tax revenues in OECD countries into the implicit tax rate (ITR) and consumption relative to GDP, to identify how economic downturns affect consumption tax revenues. It further considers the impact of changes in VAT efficiency and VAT rates on ITRs. The analysis finds that the observed stability in consumption tax revenues results from offsetting changes in the ITRs and in consumption as a share of GDP, arising from both macroeconomic changes and intentional policy changes. During the economic crisis in 2007-2009, lasting changes in consumption patterns, notably increases in government spending and in private consumption of necessity goods, adversely affected the efficiency of VAT systems. These changes have not since been reversed, suggesting that consumption tax revenues are now less robust to economic shocks. Broadening the VAT base and narrowing the scope of reduced rates can help to stabilise consumption tax revenues during economic downturns.

This report provides practical guidance to tax authorities on the design and implementation of a variety of solutions for digital platforms, including e-commerce marketplaces, in the effective and efficient collection of VAT/GST on the digital trade of goods, services and intangibles. In particular, it includes new measures to make digital platforms liable for the VAT/GST on sales made by online traders through these platforms, along with other measures including data sharing and enhanced co-operation between tax authorities and digital platforms. It builds on the solutions for the effective collection of VAT/GST on digital sales included in the International VAT/GST Guidelines and the 2015 BEPS Action 1 Final Report 'Addressing the Tax Challenges of the Digital Economy.' It is of particular relevance recognising the growing importance of the platform economy and notably the potential of digital platforms to significantly enhance the effectiveness of VAT/GST collection given their important role in generating, facilitating and/or executing online sales.
