In Brazil, discussions regarding the management of infrastructure concessions and public-private partnerships (PPPs) have moved from administrative oversight to high-level legal disputes. Initially, audit courts convened in Brasília to address the complexities of long-term contracts, focusing on risk pricing, contract extensions, and ensuring that contract execution results in high-quality services. Officials noted the difficulty of structuring these decades-long agreements to balance investment and operating costs. Following these regulatory discussions, the legal focus shifted to the Supreme Federal Court (STF), which is reviewing whether private companies managing public infrastructure are entitled to reciprocal tax immunity. The court is examining whether municipalities can levy the Municipal Property and Territorial Tax (IPTU) on private concessionaires using public land. In one instance, Justice Dias Toffoli proposed recognizing tax immunity, arguing that properties dedicated to essential public services remain reversible to the state. ## Timeline ### 2026-09-27: Brazil Supreme Court to decide IPTU tax immunity for infrastructure concessionaires The Brazilian Supreme Federal Court is deciding if private companies managing public infrastructure, such as railways and ports, are exempt from municipal property tax (IPTU) under constitutional immunity. 2 sources. https://clstr.news/cluster/brazil-supreme-court-to-decide-iptu-tax-immunity-for-infrastructure-concessionaires ### 2026-09-20: Brazilian audit courts discuss oversight of infrastructure concessions Brazilian audit courts are meeting in Brasília to discuss improved oversight, risk management, and conflict resolution for infrastructure concessions and public-private partnerships. 2 sources. https://clstr.news/cluster/brazilian-audit-courts-discuss-oversight-of-infrastructure-concessions --- Cite as: Brazil infrastructure concession regulation and taxation.
