The errors that trigger GST notices, blocked e-way bills and cancelled registrations, how to respond, and the official portals where every rule can be checked.
A missed return in GST is rarely just a late fee. Two missed GSTR-3B returns can block e-way bill generation, continued non-filing can lead to suspension and cancellation of registration, and mismatches between what you report and what the system sees produce intimations and notices. Many of these problems start with a weak process or a careless choice of software or adviser.
The guide to common GST filing mistakes links to every guide in this section. The others explain scrutiny and demand notices, registration suspension and cancellation for non-filing, switching accounting software without losing records or the audit trail, working with a CA or GST practitioner safely, matching GST turnover with your books and income-tax return, and the official portals you should rely on.
We describe patterns, not individual cases. For a notice involving a large amount, fraud allegations or a deadline you cannot meet, consult a chartered accountant, a GST practitioner or an advocate. Verify every rule on the GST portal, CBIC and the GST Council.
