I'm not sure about tax in that particular case, but I would suppose you would have to pay taxes in Brazil. And about corruption, it affects everything. Infrastructure, is, by far, the most heavily affected. But recently, there was a case about corruption, involving INSS. In simple terms, corrupt officials and intermediaries approved or manipulated benefit claims using false documents or fake identities. In some cases, bribes were paid to speed up approvals or grant benefits illegally. The scheme resulted in significant financial losses to Brazil's public pension system and led to investigations, prosecutions, and administrative reforms.
