Practical Q&A

What is the first control?
Fix the transaction date, jurisdiction, registration status and document trail before applying the workflow.
Which legal layers apply?
Sections 16-21; Rules 36-45; relevant notifications, circulars, forms, State law and portal versions.
What should the working paper contain?
Facts, issue, sources, computation, assumptions, evidence, conclusion, reviewer and date.
Is portal acceptance final legal validation?
No. Portal acceptance does not cure a statutory eligibility, valuation, classification, limitation or jurisdiction defect.
