SAP FI tax configuration is not wrong. It is a correct answer to the question it was designed to answer: given this transaction, in this company code, with this account assignment, what is the applicable tax code? That question has a deterministic answer that the SAP condition record architecture provides reliably and efficiently. The problem is not the answer. The problem is that real-time compliance mandates have changed the question.

The question that a CTC mandate asks of the tax system is not what tax code applies. It is: is this transaction compliant with the current version of the applicable mandate, does it contain every mandatory field that the authority's clearance system will validate, can it be digitally signed using the current certificate chain, and can it be transmitted to the authority's API endpoint before the document is posted? None of these questions can be answered by a condition record. None of them can be resolved by an ABAP exit. None of them can be addressed by extending the standard SAP tax determination framework without building, in effect, a compliance system inside the ERP — a system that must be updated every time a mandate changes, tested every time SAP is upgraded, and maintained by the SAP team regardless of whether the SAP team has tax compliance expertise.

The brief this episode makes is the same brief that every organisation facing an imminent CTC mandate needs to hear before their implementation project begins: externalise the tax logic. Not extend it. Not enhance it. Move it outside the SAP core to a dedicated compliance engine that was designed to answer the real-time question, maintained by people whose job is to keep it current with the mandate, and connected to SAP through a stable API that survives SAP releases. The compliance outcome is better. The SAP system is cleaner. And the next mandate does not require a new SAP project.
