Cisneros widow faces $3bn tax claim and Maduro-linked bribery allegations as Venezuela scrutinises Digitel

Two figures sit at the heart of the Venezuelan government’s growing case against the business empire of the late tycoon Oswaldo Cisneros: an inheritance-tax bill of more than $3 billion that officials say has no record of being paid, and more than $1 billion in financing that authorities allege was promised and never provided. Officials also allege that investment commitments went unmet for more than a decade across the empire, including the telecommunications operator Digitel and real estate, and that bribes and gifts were connected with those contracts.
Both now land at the door of his widow, Mireya Blavia de Cisneros, who oversees an empire that includes Digitel, Venezuela’s leading telecommunications operator, along with interests in real estate, oil and other sectors. Authoritative government sources say that empire is facing growing scrutiny over its record, and that the examination reaches well beyond any single figure, company or deal.
A senior official said authorities were looking not merely at one transaction but at what they described as a pattern running across the family’s telecommunications, real-estate, oil and other interests. “That expansion and investment never materialised in all business sectors,” the official alleged. According to the official, the allegation under examination is that the family treated major Venezuelan businesses as sources of cash while failing to invest what was required, enriching themselves and looting the Venezuelan economy while leaving investment obligations unfulfilled.
Government sources say the scrutiny extends to personal and corporate tax liabilities, to failures to meet major investment commitments stretching back more than a decade, and to sham or fraudulent adoptions designed to alter control of the Cisneros family trust and deprive rightful heirs of their due share in the businesses. At its centre are her own business dealings, including what sources describe as the use of bribes to bend regulatory and government systems in pursuit of commercial advantage.
According to a government official, the SENIAT tax authority valued Oswaldo Cisneros’s estate at more than $10 billion and calculated the state’s inheritance-tax entitlement at 30 per cent, a sum exceeding $3 billion. “There is no record of the tax payment,” the official alleged.
The official said authorities were examining how the estate and family trust had been administered after his death, and alleged that his widow was seriously in default of fiscal and personal tax obligations. “She faces a major inheritance-tax issue following Oswaldo Cisneros’s death,” the official said.
The official went further, alleging that the question of who controls the trust is bound up with the question of what is owed. “We believe that she manipulated the Cisneros heirs, carried out fake and fraudulent adoptions as part of a scheme, and took control of the family trust through deception in order to obtain majority voting control,” the official said. The adoptions, in the official’s account, were not private family matters but part of a deliberate arrangement to change voting power and control over the trust and the businesses tied to the estate.
Venezuelan Supreme Court records show that Mireya Blavia de Cisneros and the heirs became involved in legal proceedings over the acceptance, inventory and administration of the estate following Oswaldo Cisneros’s death.
Citing documents reviewed, a senior official said she was also facing a probe for not paying inheritance and succession taxes after her husband’s death, that tax authorities were reviewing the wider arrangement, and that the investigation had identified serious corruption involving bribes and gifts connected with telecommunications and real-estate contracts.
The second figure comes from oil. Venezuelan authorities allege that when Oswaldo Cisneros’s family entered a major oil deal in 2016 under a contract with the government, it was supposed to provide more than $1 billion in financing but provided no funds. The business plan envisaged roughly tripling production to 115,000 barrels per day. By July 2026, the company was producing only around 9,000 barrels per day, with zero investment in infrastructure and a failure to meet almost every financial commitment.
According to Bloomberg, Venezuela’s Petroleum Ministry recently revoked DP Delta’s minority participation after alleging that the company had failed to fulfil investment commitments and production plans, all while making huge profits through political bribes to Nicolás Maduro and his associates at the cost of ordinary Venezuelan taxpayers.
The DP Delta Finance arrangement dated from 2016 and was intended to run until early 2027. Cisneros appeared alongside Maduro as the billion-dollar financing was promoted, one visible element of a relationship that developed during a period when major Cisneros business interests and investments were operating in Venezuela. Government sources stress, however, that the oil dispute is only one part of a much wider examination of the family’s telecommunications, real-estate, tax and commercial affairs.
Sources allege that the family’s arrangements benefited from Mireya Blavia de Cisneros’s close association with Maduro, who ruled Venezuela from 2013 until US forces captured him in Caracas in January 2026 on charges of narco-terrorism and cocaine-trafficking conspiracy.
A senior Venezuelan government official alleged that the expansion and investment never materialised in any sector, calling it a corrupt scheme run and facilitated through bribes to Maduro, his aides and compromised officials. The same official alleged there was clear evidence that she had close ties with narco and cocaine-trafficking gangs, and said law enforcement was looking into all aspects of her activities, including her ongoing ties to, and funding of, elements still loyal to Maduro.
Another senior official alleged that since her husband’s death she had run the family’s affairs with the protection and assistance of Maduro and individuals associated with his government. Speaking on condition of anonymity, the official alleged that she personally managed this corrupt relationship and funded the corrupt Maduro establishment.
Among the businesses under the spotlight, Digitel carries particular weight. Oswaldo Cisneros built a major position in Venezuela’s telecommunications industry, and Digitel, one of the country’s biggest operators and among the family’s most important businesses, became one of its principal mobile operators. After his death, his widow assumed a significant role in overseeing the family’s extensive interests.
Officials say questions have arisen over infrastructure investment, the fulfilment of commercial commitments, personal and corporate tax liabilities and the wider management of telecommunications interests controlled by or associated with her.
A senior official said it was a scandal that Cisneros interests had made no investment for years, and that she and Digitel had questions to answer over the non-payment of personal taxes and liabilities. “They only looted and plundered without investing anything, while making wild excuses,” the official alleged.
In a telephone interview, a legal source working for the widow acknowledged that the family businesses had suffered from serious mismanagement, lack of investment and failures to fulfil commitments made to the government. The source attributed those problems in part to US sanctions on Venezuela’s financial system, and said they were aware of the ongoing scrutiny of Mireya Blavia de Cisneros and would fully cooperate with the authorities.
A former senior executive who acted on the widow’s behalf offered a harsher account. The family and senior company executives, the executive said, treated major business interests as a “cash cow” while failing to make the investment needed to develop and sustain operations.
“There was no investment in infrastructure development. Even basic due diligence was not put in place, and it appeared that the entire operations had been orphaned,” the former executive alleged.
“We raised several alarm bells over the course of nearly 10 years, but the owners showed no interest in fulfilling their investment and business commitments,” the executive said, adding that it was this complete lack of investment that ultimately forced the government to take notice.
Chronic underfunding, mismanagement and irregularities, the former executive alleged, affected operations, working conditions and employees.
