The API route does the real tax math before calling OpenAI — net income, SE tax at 15.3%, reasonable S-Corp salary at 50% of net income, estimated savings. Those numbers get passed into the prompt so the AI is explaining pre-computed values, not guessing. It also handles edge cases: if your income is under $80K, it flags that S-Corp election costs more than it saves at that level.
The AI's job is the human-friendly explanation and a set of deduction opportunities specific to your business type.
The OpenAI key lives server-side only and never touches the client.
