The investigation of the authority began after media reports suggested that the entity had engaged in discriminatory auditing that resulted in a HUF 1 trillion shortfall of revenue from VAT. The NAV report termed this as an issue “not supported by concrete evidence”.

Tax chief Ildikó Vida earlier confirmed that she was among those at the authority who were informed by the U.S. embassy that they had been blacklisted on the basis of a presidential order banning entry to the United States to persons involved in or profiting from corruption.
