What changed

The rules just changed.
Most filers haven't caught up.

From April 1, 2025, the personal relief threshold rose to Rs. 1,800,000. The 12% slab disappeared. AIT on interest doubled to 10%. SVAT is being repealed in October. And e-Filing is now mandatory.

An AI that won't
make up tax law.

Most AI assistants hallucinate. Ours can't. The TaxWise AI is wired into our deterministic calculation engine: it can query the engine, but it never invents numbers, citations, or rules. Ask "Show me what I owe if I add Rs. 200,000 of bank interest" and the answer carries a citation back to the Inland Revenue Act.
