On July 15, 2025, the Brazilian Senate (Senado Federal) approved the Brazil-Poland Income Tax Treaty (“the Treaty”), via Draft Legislative Decree No. 261/2024 (decreto legislativo (PDL) 261/2024).1 The Senate’s approval of the Treaty marks a crucial step towards its implementation. While not yet effective, the Treaty will introduce comprehensive rules to eliminate double taxation, prevent tax evasion, and facilitate cross-border cooperation.
The Treaty reflects the deepening economic relationship between Brazil and Poland, facilitating trade, investment, and mobility by providing tax certainty and reducing the risk of double taxation. The agreement incorporates OECD/G20 BEPS standards, including anti-abuse provisions, mutual agreement procedures, and information exchange mechanisms. Once effective, the Treaty will apply to income paid or arising from 1 January of the year following entry into force, affecting tax planning for 2026 and beyond.
