Revocation of cancellation is the legal mechanism under Section 30 of the CGST Act, 2017 and Rule 23 of the CGST Rules, 2017, through which a taxpayer whose GST registration has been cancelled by a tax officer on the officer's own motion (suo moto) can apply to have that cancellation reversed and the registration restored. The application is filed electronically in Form GST REG-21 on the GST portal, and, if approved, reinstates the original GSTIN — with its original registration date and history intact — rather than requiring a fresh registration.
Revocation is available only where the registration was cancelled by the department itself; it does not apply where the taxpayer voluntarily applied for and was granted cancellation, since a voluntary cancellation cannot be reversed and would instead require an entirely fresh registration if the business later becomes liable to register again.
The revocation application relies heavily on proof of compliance. Taxpayers must compile the following supporting evidence before starting the application:
| Category | Prescribed Document & Verification Profile |
|---|---|
| 3.1 Order Copy & Filings |
• Cancellation Order: Copy of Form GST REG-19 issued by the tax officer, noting the precise reference number and official date of service. • Filing Proofs: Reference numbers (ARNs) and copies of all returns filed to clear defaults up to the effective cancellation timeline. • Challan Receipts: Direct system payment receipts proving settlement of all related interest obligations and late fees. |
| 3.2 Premises & KYC Verification |
• Address Proof: If cancelled due to non-existence, recent electricity bills, tax receipts, or a valid rental agreement with a fresh NOC to prove operational reality. • Geo-tagged Photos: Photographic evidence showing the principal business location with signage displaying the business name and active GSTIN. • Identity Dossier: KYC records, PAN cards, and authorization letters for promoters, directors, or the main authorized signatory. |
| 3.3 Formal Explanations |
• Written Representation: A detailed statement outlining the valid reasons for the default (e.g., medical issues, technical portal glitches, business disruptions) and a formal commitment to maintain regular compliance moving forward. • Condonation Petition: A formal application explaining the specific reasons for the delay if applying past the standard 90-day filing window. • Digital Credentials: Active Class 3 DSC token or OTP access on the registered phone/email to sign and submit the portal documents. |
The revocation application is handled completely online through the official GST portal under Services > Registration > Application for Revocation of Cancelled Registration, following this structured workflow:
Before accessing the form, log into the GST portal and navigate to the returns dashboard. File all pending returns up to the cancellation date, clear all outstanding tax liabilities, interest, and late fees using the cash ledger, and secure system confirmations for these rectifications.
Navigate to the Revocation link under registration services. Complete Form GST REG-21 by entering the justification for restoring the registration, uploading the necessary property documents or explanatory letters, and submitting the application using EVC or a Class 3 DSC token to generate an Application Reference Number (ARN).
The tax officer reviews the ARN within 30 days. If the response is satisfactory, the officer issues an approval order in Form GST REG-22 to restore the registration. If clarification is needed, a notice is issued in Form GST REG-23; the taxpayer must reply within 7 working days using Form GST REG-24. If the response is insufficient, a rejection order is issued in Form GST REG-05.
