New Act section lookup — verified, not guessed.

India replaced its 65-year-old Income-tax Act on 1 April 2026. Every section number changed. This tool maps any old section, TDS payment code or topic to its place in the Income-tax Act, 2025 — using the same verified tables that power our notice-reply engine. Nothing here is model-generated.

Why we can show this for free

This lookup is the proven core of our notice-reply engine, not the product itself. The product is the drafting workflow — a 3–6 hour notice reply becomes a 30-minute review because every section, payment code and form number in the draft is machine-verified against these same tables before a professional sees it.

In our locked 785-task eval (sha256 14ffaa7d…), the best frontier model scored 30.2% strict accuracy; on the 4-part compliance task a notice reply actually needs, every model we could run scored 0. The deterministic engine answers the same code-lookup tasks at 100%. Full method + per-model answer files: itact-785.
