Türkiye’s Tax Inspection Board (VDK) identified undeclared income worth about ₺15 billion ($362 million) after launching an oversight program targeting high-income individuals linked to large companies, the Treasury and Finance Ministry announced.
The program, introduced in May, monitors taxpayers whose declared income does not match their spending levels or who failed to submit income tax returns despite holding stakes in major corporations.
Authorities said around 1,000 individuals filed income tax returns for the first time after being included in the program.
Their filings accounted for more than ₺1.2 billion ($29 million) in taxable income.
Following consultations, another 1,000 taxpayers agreed to issue profit distribution decisions in their companies, generating an additional ₺5.9 billion ($142 million) in declared income.
The initiative also directly affected companies. About 1,200 large corporations linked to these taxpayers revised their filings, increasing their corporate tax bases by ₺7.7 billion ($186 million).
While most taxpayers complied with the measures, authorities confirmed that audits will be launched against those who failed to align their declarations.
Treasury and Finance Minister Mehmet Simsek said that since the beginning of the year, oversight efforts have covered more than 50,000 taxpayers with high income or spending profiles.
He added that the proportion of large taxpayers audited rose from 11% last year to 32% this year, stressing that the aim is to secure due tax payments while improving fairness and efficiency in the system.
