Revocation of Cancelled GST Registration: Step-by-Step Legal Procedure, Form GST REG-21 & Time Limits

Under the Goods and Services Tax (GST) regime, cancellation of a GSTIN by the tax department (Suo Moto cancellation) brings business operations to an immediate halt. You can neither issue valid tax invoices nor pass on Input Tax Credit (ITC) to your buyers. However, the law provides a clear statutory remedy to revoke and restore a cancelled GST registration.

Why Does the GST Department Cancel Registration Suo Moto?

Under Section 29(2) of the CGST Act, 2017, the Proper Officer can cancel a registration on specific statutory grounds:

1. Continuous Non-Filing of Returns: Regular taxpayers failing to file returns (GSTR-3B) for continuous tax periods (typically 6 months) or composition taxpayers failing for 3 consecutive tax periods.
2. Non-Commencement of Business: Voluntary registered taxpayers who fail to commence commercial business within 6 months from registration.
3. Registration Obtained by Fraud: Misstatement, willful suppression of facts, or non-existent principal place of business during physical verification.
4. Availing Fake ITC: Significant mismatch between GSTR-2B and GSTR-3B under Rule 86B or Section 16(2)(aa).

Statutory Time Limit for Filing Revocation Application (Form GST REG-21)

Under Section 30 of the CGST Act read with Rule 23:

• Standard Time Window: An application for revocation must be submitted within 30 calendar days from the date of service of the cancellation order.
• Extension by Joint / Additional Commissioner: On showing sufficient cause, the period can be extended by a further 30 days.
• Extension by Commissioner: In exceptional situations, the jurisdictional Commissioner can grant an extension of an additional 30 days (total up to 90 days).
• Beyond 90 Days (Appeals Route): If the 90-day window has expired, revocation can only be sought by filing an appeal before the Appellate Authority under Section 107 in Form GST APL-01 within 3 months (+ 1 month condonation).

Pre-requisites Before Applying for Revocation

2. Pay All Outstanding Tax, Interest, and Late Fees: Any unpaid tax liabilities, accumulated 18% interest under Section 50, and late fees must be paid in full through the electronic cash ledger.
