Indian tax expertise for AI evaluation.
Indian indirect tax turns on exceptions, provisos and circulars that change often. A general-purpose AI can answer a GST question fluently and still be wrong in a way that only a practitioner would catch. This is our first and deepest domain.

Why tax is where we started
GST touches almost every business transaction in India. The answer to a simple-looking question — can this credit be claimed? — often depends on one condition, one exception or one recent clarification. AI trained on older or general material gets those cases wrong confidently.
It is also a domain where the answer can be proved. Every certified answer traces to the Act, the rules, a notification or a circular, with a "valid as of" date. That makes it ground truth, not opinion. How answers are tied to evidence.

Capability, not just credentials
Zynoviq does not simply recruit CAs. It identifies professionals with the relevant demonstrated capability. A qualification gets a professional considered. Their judgment counts only after they pass assessment in the specific area they will work on — for example:
- 01GST
- 02Input tax credit
- 03Reconciliation
- 04EligibilityQualified capability
A practitioner strong on place of supply may not be the right person to certify a reconciliation case. We route work by capability. How we qualify professionals.
