The Türkiye Tax Engine
Cassandra's Türkiye tax engine reasons over Turkish primary sources rather than a generic global model. Answers name the statute, the section, and the Gelir İdaresi Başkanlığı (GİB) guidance relied on, so sworn-in CPAs (YMM), CPAs (SMMM), avukatlar can verify the reasoning before it reaches a client.
Where a regime is in transition — currently Domestic minimum corporate tax and inflation accounting rules — 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.
