Traders may not pay the correct amount of Value Added Tax (VAT) for a number of reasons including error, deliberately understating their VAT liabilities or through systematic attacks on the VAT system, with an estimated £11.9 billion lost in VAT in 2002-03. Following on from the NAO's report (HCP 357, session 2003-04; ISBN 0102927375), the Committee's report examines the scale of losses; ways of preventing and detecting fraud and other non-compliance; and methods of investigating and dealing with fraudsters. Findings include: there is scope for greater data sharing with the Inland Revenue to detect traders who are evading VAT by operating in the shadow economy (likely to be improved with the creation of the new revenue department); data sharing with other member states is particularly important in tackling missing trader fraud; more investigations and prosecutions for all types of VAT fraud would be cost effective; and Customs should make greater use of sanctions against under-declarations by accountants, lawyers and tax advisers, whilst working with the business community and professional bodies concerned to agree criteria for reporting and the remedial action expected.

Like any tax, the VAT is vulnerable to evasion and fraud. But its credit and refund mechanism does offer unique opportunities for abuse, and this has recently become an urgent concern in the European Union (EU). This paper describes the main forms of noncompliance distinctive to a VAT, considers how they can be addressed, and assesses evidence on their extent in high-income countries. While the practical significance of current difficulties in the EU should not be over-stated, administrative measures alone may prove insufficient to deal with them, and a fundamental redesign of the VAT treatment of intra-community trade required. The current difficulties in the EU largely reflect circumstances that would not apply in the United States.

Technology is fast becoming an indispensable tool for tax authorities. This report provides an overview of some of the technology tools that tax authorities have implemented to address tax evasion and tax fraud, focussing on electronic sales suppression and false invoicing.

Missing Trader Intra-Community Fraud (also known as carousel fraud), where goods are repeatedly exported and imported with the EU, has caused a considerable loss of revenue In 2005/6 it is estimated the UK lost between £3-4.5 billion. This report looks both at some of the measure that have been taken to recoup some of this money and measures to stop fraud occurring. In addition it considers whether the Government's policies have imposed an unreasonable burden upon legitimate businesses within affected sectors. It concludes that not only are existing measures unsustainable, steps need to be taken to ensure innocent traders are not damaged. The government needs to work with Member States to implement a system of taxation of intra-Community transactions that will be less vulnerable to major fraud.

The value-added tax (VAT) has the potential to generate significant government revenue. Despite its intrinsic self-enforcement capacity, many tax administrations find it challenging to refund excess input credits, which is critical to a well-functioning VAT system. Improperly functioning VAT refund practices can have profound implications for fiscal policy and management, including inaccurate deficit measurement, spending overruns, poor budget credibility, impaired treasury operations, and arrears accumulation.This note addresses the following issues: (1) What are VAT refunds and why should they be managed properly? (2) What practices should be put in place (in tax policy, tax administration, budget and treasury management, debt, and fiscal statistics) to help manage key aspects of VAT refunds? For a refund mechanism to be credible, the tax administration must ensure that it is equipped with the strategies, processes, and abilities needed to identify VAT refund fraud. It must also be prepared to act quickly to combat such fraud/schemes.

A previous IMF Working Paper on value-added tax (VAT) refunds (WP/07/31, by Keen and Smith) describes the main forms of VAT noncompliance and concludes that VAT is susceptible to evasion and fraud like any other tax. This paper shows the insidious nature and extent of VAT refund fraud in selected EU countries and argues that this type of noncompliance requires tax administrations to adopt a coordinated strategy and deploy a range of countermeasures to combat this threat. Because such fraud is primarily a criminal legal issue, tackling it successfully will require cooperation, both internationally between VAT administrations and nationally between tax authorities and the judiciary. The paper’s focus is primarily on advanced economies in the context of the EU, but many of the recommendations are applicable to emerging market and developing countries. A separate IMF How to Note discusses managing VAT refunds in developing countries.
