$3 billion inheritance tax unpaid, Venezuelan officials allege, as Cisneros widow faces widening probe. Venezuela’s SENIAT tax authority valued the estate of tycoon Oswaldo Cisneros at more than $10 billion and calculated the state’s inheritance-tax entitlement at 30 per cent, a sum exceeding $3 billion, according to a Venezuelan government official, who alleged that there is no record of the tax being paid.
The alleged unpaid bill is one strand of growing scrutiny of the business empire now overseen by his widow, Mireya Blavia de Cisneros, authoritative Venezuelan government sources say. That scrutiny covers her record in handling a wide range of businesses, among them Digitel, Venezuela’s leading telecommunications operator, along with interests in real estate, oil and other sectors.
The official alleged that Mireya Blavia de Cisneros was seriously in default of fiscal and personal tax obligations, and said authorities were examining the administration of Oswaldo Cisneros’s estate and family trust following his death.
“She faces a major inheritance-tax issue following Oswaldo Cisneros’s death,” the official said. “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.”
In the official’s account, the heirs’ adoptions were no mere private family matter. They formed, the official alleged, part of a deliberate arrangement intended to shift voting power and control over the trust and the businesses associated with the Cisneros estate. Government sources describe the adoptions as sham or fraudulent, designed to alter control of the family trust and deprive rightful heirs of their due share in the businesses.
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 Oswaldo Cisneros’s estate after his death.
A senior official said: “According to the documents reviewed, Mireya Blavia de Cisneros is also facing a probe for not paying inheritance and succession taxes following the death of her husband. The tax authorities are reviewing the wider arrangement. The investigation has identified serious corruption involving bribes and gifts connected with the telecommunications and real-estate contracts.”
Taxes, however, are only part of the picture. Government sources say the scrutiny extends to personal and corporate tax liabilities and to failures to meet major investment commitments stretching back more than a decade.
At the centre of the government’s attention are Mireya Blavia de Cisneros’s business dealings: failures to meet investment commitments across major interests, including telecommunications and real estate; failures to pay personal and corporate taxes and liabilities that were due; and the alleged use of bribes to bend regulatory and government systems for commercial advantage.
Government sources further allege that these arrangements benefited from her close association with Nicolás Maduro, who ruled Venezuela from 2013 until he was captured by US forces in Caracas in January 2026 on charges of narco-terrorism and cocaine-trafficking conspiracy.
A senior official said authorities were examining not merely one transaction or company, but what they described as a pattern running across the Cisneros telecommunications, real-estate, oil and other business interests.
“That expansion and investment never materialised in all business sectors,” the senior official alleged. “The allegation being examined is that they treated major Venezuelan businesses as sources of cash while failing to invest what was required. They enriched themselves and looted the Venezuelan economy while leaving investment obligations unfulfilled.”
Digitel is a major focus. One of Venezuela’s biggest telecommunications operators, it is among the most important businesses associated with the Cisneros family. Oswaldo Cisneros built a major position in the country’s telecommunications industry, with Digitel becoming one of its principal mobile operators. Following his death, Mireya Blavia de Cisneros assumed a significant role in overseeing the family’s extensive business interests.
Officials say questions have arisen over investment in infrastructure, the fulfilment of commercial commitments, personal and corporate tax liabilities and the wider management of the telecommunications interests controlled by or associated with her.
“It is a scandal that Cisneros interests made no investment for years,” a senior government official said. “Mireya Blavia de Cisneros and Digitel have questions to answer in relation to the non-payment of personal taxes and liabilities. They only looted and plundered without investing anything, while making wild excuses.”
In the oil sector, 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 Maduro and his associates at the cost of ordinary Venezuelan taxpayers.
Venezuelan authorities allege that when Oswaldo Cisneros’s family entered the major oil deal in 2016 under a contract with the Venezuelan government, it was supposed to provide more than $1 billion in financing but provided no funds. The business plan envisaged production roughly tripling to 115,000 barrels per day. By July 2026, the company was producing only around 9,000 barrels per day, a fraction of the original target, with zero investment in infrastructure and a failure to meet almost every financial commitment.
The family’s relationship with Maduro developed during a period in which major Cisneros business interests and investments were operating in Venezuela. One visible element was the DP Delta Finance arrangement of 2016, which was intended to run until early 2027. Cisneros appeared alongside Maduro as the billion-dollar financing arrangement was promoted.
The government has alleged that the venture’s investment and production commitments were not fulfilled. Government sources say, however, that the oil dispute represents only one part of a much wider examination of the family’s telecommunications, real-estate, tax and commercial affairs.
A senior Venezuelan government official alleged: “That expansion and investment never materialised in all business sectors. This was a corrupt scheme run and facilitated through bribes to Nicolás Maduro, his aides and compromised officials.”
The official also alleged: “There is clear evidence that Mireya Blavia de Cisneros has close ties with narco and cocaine-trafficking gangs. Law enforcement is looking into all aspects of her activities, including her ongoing ties to, and funding of, elements still loyal to Nicolás Maduro.”
According to a senior official, Mireya Blavia de Cisneros had run the family’s affairs since her husband’s death under the protection and with the assistance of Maduro and individuals associated with his government. “Mireya Blavia de Cisneros personally managed this corrupt relationship and funded the corrupt Maduro establishment,” the official alleged, speaking on condition of anonymity.
A legal source working for Oswaldo Cisneros’s widow acknowledged in a telephone interview that the family businesses had suffered from serious mismanagement, lack of investment and failures to fulfil commitments made to the government, but attributed those problems in part to US sanctions on Venezuela’s financial system.
“We are aware of the ongoing scrutiny of Mireya Blavia de Cisneros and we will fully cooperate with the authorities,” the source said.
A former senior executive who acted on the widow’s behalf said the Cisneros family and senior company executives 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. It was this complete lack of investment that ultimately forced the government to take notice.”
The former executive alleged that chronic underfunding, mismanagement and irregularities affected operations, working conditions and employees.
