Note: The US and Brazil have never concluded a comprehensive income tax treaty. Negotiations have been discussed for decades but no convention has been finalised as of May 2026. Brazil is not on the IRS A-to-Z list of US income tax treaties. US-source FDAP payments to Brazilian residents face default 30% US WHT with no treaty relief.

PE Threshold Notes — Americas
| Corridor | Construction PE Threshold | Service PE | Notes |
|---|---|---|---|
| US → CA | 12 months | None (Art XIV merged) | Fifth Protocol merged services into Art VII |
| US → MX | 6 months | 183 days in any 12-month period | Shorter than standard — monitor near-shoring |
| US → BR | No treaty | No treaty | Brazil domestic PE rules apply |
| BR → AR | 6 months | 6 months | Short threshold |
| CA → UK | 12 months | None | Standard OECD |
| MX → ES | 6 months | 183 days | Mexico standard |
| CL → ES | 6 months | 183 days | Chile standard |
| CO → ES | 12 months | 183 days | Colombia standard |
Mexico and Chile use 6-month construction PE thresholds — significantly shorter than the OECD 12-month standard. This is critical for infrastructure and energy projects.
Brazil has one of the most limited treaty networks among major economies:
Brazil Treaty Partner Rates
| Brazil Treaty Partner | Dividends | Interest | Royalties | Notes |
|---|---|---|---|---|
| Argentina | 15% | 15% | 10%/15% | MERCOSUR partner |
| Chile | 10%/15% | 10%/15% | 10%/15% | 2026 Protocol cuts rates |
| Portugal | 10%/15% | 15% | 15% | Historic Lusophone tie |
| Japan | 12.5% | 12.5% | 12.5%/15%/25% | Category-dependent |
| India | 10%/15% | 10%/15% | 10%/15%/25% | 2022 Protocol (effective 2026) |
| France | 10%/15% | 10%/15% | 15%/25% | Older treaty |
| Spain | 10%/15% | 10%/15% | 10%/15% | Key EU partner |
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.
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.
Latin American WHT rates are generally higher than OECD/European rates. Treaty negotiations tend to produce rates of 10-15% rather than 0-5%.
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.
Canada's split royalty approach (0% copyright/software vs 10% industrial) is consistent across its treaty network and materially affects tech/media planning.
Near-shoring impact: Mexico's 6-month PE threshold requires careful structuring for US companies establishing manufacturing/service operations under USMCA.
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.
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%.
