Overview

Where the proper officer has cancelled your registration suo-motu, the law provides a remedy to restore it: revocation. This is available only for officer-initiated cancellations and is filed in Form GST REG-21 after curing the defaults that led to cancellation.

When It Is Required & Legal Basis

Section 30 of the CGST Act, 2017 read with Rule 23 of the CGST Rules, 2017 provides for revocation. It applies where registration was cancelled by the officer under Section 29(2). A pre-condition, especially for cancellation due to non-filing, is that all pending returns are filed and all dues (tax, interest, late fee, penalty) are paid.

Step-by-Step Process

  1. File all pending returns. Clear GSTR-3B and GSTR-1 up to the effective date of cancellation with tax, interest and late fee.
  2. Open the application. Go to Services → Registration → Application for Revocation of Cancelled Registration.
  3. State the grounds. Explain why revocation should be granted and attach supporting documents (return ARNs, challans).
  4. Submit REG-21. File with DSC or EVC; an ARN is generated.
  5. Respond to any notice. If the officer needs clarification, a notice in Form GST REG-23 is issued; reply in Form GST REG-24 within seven working days.
  6. Restoration order. On satisfaction, the officer passes Form GST REG-22 restoring the registration within 30 days.

Timeline & Due Dates

File REG-21 within 90 days of the date of service of the cancellation order. This can be extended by 90 days by the Additional/Joint Commissioner and by a further 90 days by the Commissioner on sufficient cause. The officer decides within 30 days of the application (or of your REG-24 reply).

Penalty for Delay / Non-compliance

There is no separate penalty for revocation, but the returns you must file to qualify carry late fees under Section 47 and interest under Section 50. Missing the 90-day (and extended) window can permanently bar restoration, forcing fresh registration.

Practical Tips

  • File the pending returns first — the portal often blocks the revocation application until returns are cleared.
  • Track the 90-day limit from the date the REG-19 order was served, not the date of the default.
  • Keep the REG-24 reply ready; the seven-day window for clarification is strict.
  • After restoration, resume normal return filing immediately to avoid a repeat cancellation.

REG-21 is the application for revocation of cancellation of GST registration, filed on the portal when your registration was cancelled suo-motu by the proper officer.

The application must be filed within 90 days from the date of service of the cancellation order (REG-19). The Additional/Joint Commissioner and then the Commissioner can extend this by further periods on sufficient cause.

No. Revocation applies only where the officer cancelled the registration suo-motu under Section 29(2). Voluntary cancellations cannot be revoked; you would apply for fresh registration.

Yes. All returns due up to the effective date of cancellation must be filed with tax, interest and late fee before or along with the revocation application.

If satisfied, the officer passes an order in Form GST REG-22 revoking the cancellation and restoring the registration; rejection is in Form GST REG-05 after a REG-23 notice and REG-24 reply.

The officer generally decides within 30 days of the application, or within 30 days of your reply to any REG-23 clarification notice.
