     This week's tax news from the Americas

  • USTR proposes action against Nicaraguan imports in Section 301 investigation
    On 20 October 2025, the Office of the US Trade Representative (USTR) announced its determination under Section 301 of the Trade Act of 1974 that Nicaragua's acts, policies, and practices related to abuses of labor rights, abuses of human rights and fundamental freedoms, and dismantling of the rule of law are unreasonable and burden or restrict US commerce. USTR is proposing a range of responsive actions, including withdrawal of preferential treatment under the Dominican Republic-Central America-United States Free Trade Agreement (CAFTA-DR) or 100% tariffs on imports from Nicaragua.
  • Argentina eliminates the mandatory disclosure regime (MDR)
    On 21 October 2025, the Argentine Tax Authority published General Resolution No. 5772/2025, repealing the informative regime for certain international transactions carried out with related foreign parties and those in non-cooperating or low-tax/no-tax jurisdictions. The repeal applies to fiscal years ending after 1 May 2025, and decreases compliance burdens by eliminating the reporting requirements for companies, nonprofit entities, trusts, mutual funds and permanent establishments in Argentina for those international transactions.
  • Brazil signs Multilateral BEPS Convention
    On 20 October 2025, Brazil signed the Organisation for Economic Co-operation and Development's Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting. This action aligns Brazil with global efforts to combat tax avoidance and enhance transparency and cooperation in cross-border taxation. Brazil must now complete domestic ratification procedures, including approval by Congress and presidential sanction, before depositing its Instrument of Ratification with the OECD.
