The world of offshore finance has once again come under scrutiny after leaked corporate records reportedly exposed how Deloitte’s Cyprus operation and its former affiliate, MeritServus, helped Russian billionaire Roman Abramovich restructure financial records to conceal billions of dollars in assets and potentially evade millions in taxes. The findings, uncovered by a joint investigation by The Bureau of Investigative Journalism (TBIJ) and BBC Panorama, raise serious questions about the role of major professional services firms in maintaining the financial secrecy of powerful oligarchs.
The investigation, based on hundreds of thousands of leaked files, alleges that financial advisers repeatedly backdated documents, altered corporate accounts and manufactured supporting paperwork to reshape the financial history of companies linked to Abramovich. Between 1999 and 2013, more than 1,000 documents were reportedly manipulated or retrospectively approved, creating an offshore paper trail that investigators say helped shield substantial wealth from scrutiny.
Andrew Mitchell KC, a barrister specialising in financial crime who reviewed the findings, described the alleged conduct as blatant tax evasion. He warned that the evidence illustrated how professionals entrusted with upholding legal and accounting standards could instead help clients circumvent them.
The allegations are particularly significant because they involve established financial advisers operating within the international accounting industry. If substantiated, they would demonstrate how sophisticated corporate structures and professional expertise can be used not merely to manage wealth, but to obscure ownership, liabilities and the movement of assets.
Billions disappear from corporate accounts
One of the most striking revelations concerns Amiscan Investments, a Cyprus-based company associated with Abramovich. Around 2006, following the introduction of new corporate disclosure requirements in Cyprus, more than $600 million in luxury assets reportedly disappeared from the company’s accounts. These assets included a French château, superyachts and private aircraft.
Another company, Kravin Investments, allegedly underwent an even more consequential financial transformation. Investigators found evidence of a yearslong effort that removed nearly $2 billion from its balance sheet by effectively rewriting its accounting history.
The changes were not merely bookkeeping adjustments, according to the investigation. They allegedly altered the apparent ownership and financial status of assets, potentially making substantial wealth less visible to tax authorities and the public.
The findings emerged from the Cyprus Confidential investigation, an international reporting project based on a leak of approximately 450,000 files from MeritServus. The material was obtained by Paper Trail Media and Distributed Denial of Secrets and shared with the International Consortium of Investigative Journalists (ICIJ).
MeritServus, a family-run financial services firm in Limassol, separated from Deloitte in 2005. Despite their formal split, leaked records reportedly indicate that the two businesses maintained close working relationships and continued to serve as important financial advisers to Abramovich for years.
Their relationship ended after the United Kingdom and European Union imposed sanctions on Abramovich following Russia’s full-scale invasion of Ukraine in 2022.
Earlier ICIJ reporting linked Abramovich to 261 companies and trusts across Cyprus, the British Virgin Islands, Jersey and other jurisdictions known for financial secrecy.
Rewriting the history of $3 billion
The investigation’s most revealing episode concerns approximately $3 billion that Kravin Investments received in 2003 from Abramovich’s sale of shares in Sibneft, the Russian oil company that helped establish his fortune.
Around $2 billion remained in Kravin’s bank account, generating interest and potentially creating a substantial tax liability in Cyprus.
Leaked emails reportedly show that members of Abramovich’s financial circle, operating from London, discussed the problem with advisers in Cyprus. Among those involved in the advisory relationship were MeritServus founder Demetris Ioannides and Antonis Taliotis, a senior tax adviser at Deloitte Cyprus until earlier in 2026.
In one email cited by the investigation, Deloitte advised that changes would have to be made to company accounts, including bank balances, interest income and profit-and-loss statements.
Beginning in 2005, MeritServus allegedly created documents backdated to 2003 to make it appear that the money had been transferred to another Abramovich-linked company in the British Virgin Islands rather than remaining in Kravin’s account.
The firm reportedly went further, drafting a backdated agreement suggesting that Kravin had held and invested the funds on behalf of the offshore company. If accepted, that arrangement could have supported the argument that the money and associated interest should not be taxed in Cyprus.
Investigators also identified allegedly fabricated correspondence between the companies and other supporting documents intended to make the revised account appear legitimate. Some of the paperwork was reportedly created years after the transactions it purported to document.
Several experts who examined the evidence concluded that the backdated records appeared designed to facilitate tax evasion.
A $10 billion fortune behind a corporate facade
The investigation also examined Electus Investments, described as a holding company at the top of Abramovich’s offshore financial empire and associated with a fortune worth approximately $10 billion.
Between 2006 and 2008, MeritServus allegedly signed and backdated documents to create the impression that a duplicate of Electus Investments, incorporated in the British Virgin Islands, had owned Abramovich’s wealth for years.
The apparent purpose was to make the original company’s financial position look dramatically smaller when its accounts became publicly available in Cyprus. According to the investigation, those accounts ultimately showed assets worth just $145,000.
Such arrangements illustrate the power of offshore corporate structures: wealth can remain substantial in economic terms while its recorded ownership and visibility are transformed through layers of companies and carefully constructed documentation.
Alex Cobham, chief executive of the Tax Justice Network, told TBIJ that Deloitte appeared to have participated in designing such arrangements on multiple occasions, rather than merely accepting proposals from another firm.
That assessment raises a broader question for regulators: whether professional advisers who design, document and administer complex offshore structures should face greater scrutiny when those structures appear to conceal assets or undermine tax transparency.
Accountability remains the central question
Abramovich’s lawyers denied that their client knew of unlawful backdating, evaded taxes or misled Cypriot authorities. They argued that companies linked to him would have been entitled to rely on advice from a professional firm of Deloitte’s standing.
Deloitte Cyprus stated that it operates in compliance with all applicable laws. Ioannides’ lawyers said he was unable to respond to requests for comment, while Taliotis declined to comment through Deloitte Cyprus.
The allegations have not, by themselves, established criminal liability. Nevertheless, the leaked records present a troubling picture of how financial expertise may be deployed to obscure the origins, ownership and tax treatment of immense private fortunes.
Abramovich built his wealth during Russia’s turbulent post-Soviet privatisation era, acquiring Sibneft for roughly $250 million before selling it back to the Russian government years later for billions. His subsequent investments included luxury property, superyachts, a major art collection and Chelsea Football Club.
The latest revelations expose the darker side of an international financial system in which the wealthy can employ armies of accountants, lawyers and offshore specialists to navigate rules that ordinary taxpayers cannot escape.
The essential issue is not whether billionaires should be permitted to organise their investments internationally. It is whether professional advisers can help powerful clients rewrite financial history while the public, tax authorities and regulators struggle to establish what those clients actually own.
When corporate paperwork becomes a mechanism for concealing rather than disclosing financial reality, accountability cannot stop with the names on the accounts. The advisers who design and maintain those arrangements must also face scrutiny. Otherwise, offshore secrecy will continue to offer the powerful a potential escape route from obligations that bind everyone else.
