Tackling tax abuse
58. Tax abuse includes tax evasion, fraud and other illegal practices, including the tax
losses resulting from other illicit financial flows, such as bribery, corruption and money
laundering. 72 Levels of tax evasion are extremely high in many countries; 73 globally,
approximately $3 trillion of government revenue is lost to tax evasion every year.74 While
high-income countries are the biggest losers in absolute terms, low- and middle-income
countries are particularly affected by the losses, and also face particular constraints when
tackling tax abuse. 75 In 2011, developing countries lost $946.7 billion owing to illicit
financial flows (a substantial portion of which relates to tax abuse),76 according to OECD
more than seven times official development assistance for that year, and substantially more
than the estimated costs of achieving the Millennium Development Goals.77
59. Tax abuse is thus not a victimless practice; it limits resources that could be spent on
reducing poverty and realizing human rights, and perpetuates vast income inequality. While
the rich benefit from this practice, the poor feel the negative impact on their standard of
living, their unequal political power and the inferior quality of health and education
services for themselves and their children. Simulations suggest that, if all the capital flight
from Africa over the period 2000-2008 had been invested in Africa, with the same
productivity as actual investment, the average rate of poverty reduction would have been 4
to 6 percentage points higher per year. 78 Meanwhile, the recent devastating austerity
measures taken in some countries could have been avoided entirely if some of the annual
revenue lost from tax evasion had been recovered.79
60. A State that does not take strong measures to tackle tax abuse cannot be said to be
devoting the maximum available resources to the realization of economic, social and
cultural rights. Moreover, high levels of tax abuse undermine the principles of equality and
non-discrimination, given that evaders end up paying less than taxpayers with the same – or
less – capacity to pay. High net-worth individuals and large corporations also have a far
greater ability to evade taxes as they are able to pay tax advisers, lawyers and accountants
(who may sometimes provide inappropriate advice and assistance) and to open undeclared
foreign bank accounts in low-tax jurisdictions. Tax abuse by corporations and high networth individuals forces Governments to raise revenue from other sources: often regressive
taxes, the burden of which falls hardest on the poor. Therefore, if States do not tackle tax
abuse, they are likely to be disproportionately benefiting wealthy individuals to the
detriment of the most disadvantaged. Monitoring, preventing and punishing abuse is
therefore essential in order to comply with human rights principles and improve the
distributive effects of tax systems.
