companies are also exempt. Due to federalism in the United States, shell companies are often set-up in states such as Delaware, Nevada, and Wyoming due to advantageous tax regimes. Abuse Shell companies have been used to commit fraud, by creating an empty shell company with a name similar to existing real companies, then running up the price of the empty shell and suddenly selling it (pump and dump). There are also shell companies that were created for the purpose of owning assets (including tangibles, such as a real estate for property development, and intangibles, such as royalties or copyrights) and receiving income. The reasons behind creating such a shell company may include protection against litigation and/or tax benefits (some expenses that would not be deductible for an individual may be deductible for a corporation). Sometimes, shell companies are used for tax evasion or tax avoidance. Offshore Leaks In 2013 the International Consortium of Investigative Journalists published a report called "Offshore Leaks" with information about the use and owners of 130,000 shell companies. Many of the shell companies belonged to politicians and celebrities from around the world and were being used for tax evasion and hiding financial assets. Panama Papers In 2016 a leak of 11.5 million documents to the German newspaper Süddeutsche Zeitung revealed information about owners of more than 214,000 shell companies administered by the law firm Mossack Fonseca in Panama. The shell companies were used by politicians, businessmen, autocrats, and terrorists from around the world for tax evasion and other illegal activities. India After India's decision to demonetise ₹500 and ₹1000 rupee notes on 8 November 2016, various authorities noticed a surge in shell companies depositing cash in banks, possibly in an attempt to hide the real owner of the wealth. In response, in July 2017, the authorities ordered nearly 2,000 shell companies to be shut down while Securities and Exchange Board of India (SEBI) imposed trading restrictions on 162 listed entities as shell companies. A high-level task force found that hundreds of shell companies were registered in a few buildings in Kolkata. Many of those were found to be locked, with their padlocks coated in dust and many others which had office space the size of cubicles. Regulation Since shell companies are very often abused for various illegal purposes, regulation of shell companies is becoming more important to prevent such illegal activities.
