Brazil's Treaty Network — Key Limitation

Brazil has one of the most limited treaty networks among major economies:

Notable absences from Brazil's treaty network: US, UK, Germany, Australia, Canada, Singapore, Netherlands. For these jurisdictions, Brazilian domestic IRRF rates apply with no treaty relief.

Key Observations

  1. Brazil's unique position: Brazil does not impose WHT on dividend distributions and has a very limited treaty network (no US treaty). Brazil's IRRF of 15% (25% for tax haven recipients) applies to most outbound payments.

  2. Latin American WHT rates are generally higher than OECD/European rates. Treaty negotiations tend to produce rates of 10-15% rather than 0-5%.

  3. Mexico's bank interest rate of 4.9% appears in multiple Mexican treaties and is one of the lowest interest rates available in the Americas.

  4. Canada's split royalty approach (0% copyright/software vs 10% industrial) is consistent across its treaty network and materially affects tech/media planning.

  5. Near-shoring impact: Mexico's 6-month PE threshold requires careful structuring for US companies establishing manufacturing/service operations under USMCA.

  6. Chile-Brazil 2026 Protocol: Brazil published Decree 12.863 on 3 March 2026 implementing the first amending protocol to the Brazil-Chile DTA. New reduced ceilings: dividends 10% (from 15%), interest 10% for qualifying banks, royalties 10%. Effective for income earned since January 2026.

  7. India-Brazil 2022 Protocol: Notified by India on 3 March 2026, effective from 1 April 2026. Reduces dividend WHT to 10%/15% (from 15%/25%), interest to 10%/15%, and royalties to 10%/15%. Introduces separate FTS article at 10%.
