Tax evasion

Smuggling is import or export of products by illegal means. Smuggling is resorted to for total evasion of customs duties, as well as for the import and export of contraband. Smugglers do not pay duty since the transport is covert, so no customs declaration is made.[8]

Corrupt tax officials co-operate with the taxpayers who intend to evade taxes. When they detect an instance of evasion, they refrain from reporting it in return for bribes. Corruption by tax officials is a serious problem for the tax administration in many countries.

Tax evasion is a crime in almost all developed countries, and the guilty party is liable to fines and/or imprisonment. In Switzerland, many acts that would amount to criminal tax evasion in other countries are treated as civil matters. Dishonestly misreporting income in a tax return is not necessarily considered a crime. Such matters are handled in the Swiss tax courts, not the criminal courts.

In Switzerland, however, some tax misconduct (such as the deliberate falsification of records) is criminal. Moreover, civil tax transgressions may give rise to penalties. It is often considered that the extent of evasion depends on the severity of punishment for evasion.

Professor Christopher Hood first suggested privatization of tax enforcement to control tax evasion more efficiently than a government department would.,[15] and some governments have adopted this approach. In Bangladesh, customs administration was partly privatized in 1991.[8]

Abuse by private tax collectors (see tax farming below) has on occasion led to revolutionary overthrow of governments who have outsourced tax administration.

Tax farming is an historical means of collection of revenue. Governments received a lump sum in advance from a private entity, which then collects and retains the revenue and bears the risk of evasion by the taxpayers. It has been suggested that tax farming may reduce tax evasion in less developed countries.[12]

This system may be liable to abuse by the "tax-farmers" seeking to make a profit, if they are not subject to political constraints. Abuses by tax farmers (together with a tax system that exempted the aristocracy) were a primary reason for the French Revolution that toppled Louis XVI.

Pre-shipment inspection agencies like Société Générale De Surveillance S. A. and its subsidiary Cotecna are in business to prevent evasion of customs duty through under-invoicing and misdeclaration.

However, PSI agencies have cooperated with importers in evading customs duties. Bangladeshi authorities found Cotecna guilty of complicity with importers for evasion of customs duties on a huge scale.[16] In August 2005, Bangladesh had hired four PSI companies – Cotecna Inspection SA, SGS (Bangladesh) Limited, Bureau Veritas BIVAC (Bangladesh) Limited and INtertek Testing Limited – for three years to certify price, quality and quantity of imported goods. In March 2008, the Bangladeshi National Board of Revenue cancelled Cotecna's certificate for serious irregularities, while importers' complaints about the other three PSI companies mounted. Bangladesh planned to have its customs department train its officials in "WTO valuation, trade policy, ASYCUDA system, risk management" to take over the inspections.[17]

Cotecna was also found to have bribed Pakistan's prime minister Benazir Bhutto to secure a PSI contract by Pakistani importers. She and her husband were sentenced both in Pakistan and Switzerland.[18]

A network of banks, stock traders and top lawyers has obtained billions from the European treasuries through suspected fraud and speculation with dividend tax. The five hardest hit countries have lost together at least $62.9 billion.[19] Germany is the hardest hit country, with around €31 billion withdrawn from the German treasury.[20] Estimated losses for other countries include at least €17 billion for France, €4.5 billion in Italy, €1.7 billion in Denmark and €201 million for Belgium.[21][22][23]

A paper by economists Annette Alstadsæter, Niels Johannesen and Gabriel Zucman, which used data from HSBC Switzerland (“Swiss leaks”) and Mossack Fonseca (“Panama Papers”), found that "on average about 3% of personal taxes are evaded in Scandinavia, but this figure rises to about 30% in the top 0.01% of the wealth distribution... Taking tax evasion into account increases the rise in inequality seen in tax data since the 1970s markedly, highlighting the need to move beyond tax data to capture income and wealth at the top, even in countries where tax compliance is generally high. We also find that after reducing tax evasion—by using tax amnesties—tax evaders do not legally avoid taxes more. This result suggests that fighting tax evasion can be an effective way to collect more tax revenue from the ultra-wealthy."[24]

Poster issued by the British tax authorities to counter offshore tax evasion.

HMRC, the UK tax collection agency, estimated that in the tax year 2016–17, pure tax evasion (i.e. not including things like hidden economy or criminal activity) cost the government £5.3 billion. This compared to a wider tax gap (the difference between the amount of tax that should, in theory, be collected by HMRC, against what is actually collected) of £33 billion in the same year, an amount that represented 5.7% of liabilities. At the same time, tax avoidance was estimated at £1.7 billion (this does not include international tax arrangements that cannot be challenged under the UK law, including some forms of base erosion and profit shifting (BEPS)).[25]

In 2013, the Coalition government announced a crackdown on economic crime. It created a new criminal offence for aiding tax evasion and removed the requirement for tax investigation authorities to prove "intent to evade tax" to prosecute offenders.[26]

In 2015, Chancellor George Osborne promised to collect £5bn by "waging war" on tax evaders by announcing new powers for HMRC to target people with offshore bank accounts.[27] The number of people prosecuted for tax evasion doubled in 2014/15 from the year before to 1,258.[28]

In the United States of America, Federal tax evasion is defined as the purposeful, illegal attempt to evade the assessment or the payment of a tax imposed by federal law. Conviction of tax evasion may result in fines and imprisonment.[29]

The Internal Revenue Service (IRS) has identified small businesses and sole proprietors as the largest contributors to the tax gap between what Americans owe in federal taxes and what the federal government receives. Small businesses and sole proprietorships contribute to the tax gap because there are few ways for the government to know about skimming or non-reporting of income without mounting significant investigations.

As of 2007 the most common means of tax evasion was overstatement of charitable contributions, particularly church donations.[30]

The IRS estimates that the 2001 tax gap was $345 billion and for 2006 it was $450 billion.[31] A study of the 2008 tax gap found a range of $450–$500 billion, and unreported income to be about $2 trillion, concluding that 18 to 19 percent of total reportable income was not being properly reported to the IRS.[6]
