Tax and legal rules are taken from official sources: the Income Tax Department, Finance Acts, the GST Council, and state registration and revenue departments. Each rule set links to its source.
Review
Every formula has automated tests. Content is drafted with AI assistance and reviewed by a human before publication. Tax and legal calculations are not approved by AI alone.
