The Brazil Tax Engine
Cassandra's Brazil tax engine reasons over Brazilian primary sources rather than a generic global model. Answers name the statute, the section, and the Receita Federal do Brasil (RFB) guidance relied on, so contadores, tax consultants, advogados can verify the reasoning before it reaches a client.
Where a regime is in transition — currently CBS/IBS consumption tax reform replacing PIS/COFINS, ICMS and ISS — Cassandra surfaces the transition and the competing treatments instead of silently choosing one. Cross-border questions combine this engine with the applicable double tax agreement, the OECD Model Tax Convention commentary, the OECD Transfer Pricing Guidelines, and BEPS Pillar One and Pillar Two materials.
