Who assesses, when, and under which section
1️⃣ What Is “Assessment” under GST? (In One Line)
Meaning
Assessment under GST is the determination of tax liability of a person either by the taxpayer himself or by the tax authority, depending on the situation, as per the CGST Act, 2017.

Proper Officer
Scope
Data mismatch, ITC excess, tax short-paid
Result

Common Scrutiny Triggers
Issue
Example
ITC mismatch
GSTR-3B > GSTR-2B
Turnover mismatch
GSTR-1 vs GSTR-3B
Rate mismatch
Wrong HSN rate
📌 Scrutiny ≠ demand. It is a pre-enforcement check.
6️⃣ Best Judgement Assessment — Sections 62 & 63
A. Section 62 — Registered Person
Applies to
Registered taxpayer
Default
Non-filing of returns
Basis
Past returns, available data
Objective
Enforce compliance
Example: Returns not filed for 6 months → Officer estimates tax → Assessment order issued.
B. Section 63 — Unregistered Person
Applies to
Liable but unregistered person
Basis
Market data, inspections, records
Consequence
Tax + penalty exposure
Example: Business crosses threshold but no GST registration → Officer assesses tax.
GST assessment is a graduated mechanism — not a single event. If returns are accurate and reconciled, most taxpayers never face officer-driven assessment.
