GST Cancellation Revocation

Overview

When a tax officer cancels a GST registration on their own motion, the taxpayer can ask for the cancellation to be withdrawn. This is revocation under Section 30 of the CGST Act. The application is made on the GST portal in Form GST REG-21. If the officer is satisfied, the registration is restored through an order in Form REG-22; if not, the application is rejected in Form REG-05.

Who needs it

• Taxpayers whose registration was cancelled by an officer for not filing returns for a continuous period.
• Taxpayers cancelled for a premises that could not be verified, where the business is actually operating.
• Taxpayers cancelled for other alleged violations who now have a valid explanation and have cleared dues.

Revocation is not available for a registration that you cancelled yourself. For that, you would apply for a fresh registration.

What Zenith does

Zenith listens first: we read the cancellation order and the earlier show-cause notice, work out the date the clock started, and tell you honestly whether the revocation window is still open. We give a tailored quotation and assign a relationship manager. Our team reconciles which returns are pending, helps you file them and compute interest and late fees, drafts the grounds for revocation, prepares REG-21 with the supporting proof and files it. We then follow it up, handle any clarification notice in Form REG-23 and share the result with an explanation of what to do next. If the window has closed, we explain alternatives such as a fresh registration or the appeal route. Appearances and representation before authorities happen only through appropriately authorised professionals, subject to eligibility and applicable rules.

Eligibility and key rules

• The cancellation must have been made by the tax officer, not by the taxpayer.
• There should be no other valid registration for the same business under the same PAN that conflicts with the revived one.
• All pending returns for the period up to the date of cancellation must be filed, and the tax, interest and late fee paid, before the application is processed.
• The application must be made within a short statutory window counted from the date of the cancellation order. Sources read give different figures (30 days in one, 90 days in another), and senior officers can extend the time on reasonable cause, so the exact limit should be confirmed against your order.
• A one-time amnesty for old cancellations was available earlier but is not in force now.
• Where the cancellation was for fraud or misstatement, a clearer justification is needed.

Documents required

• Copy of the cancellation order and of the show-cause notice.
• Written explanation or justification letter for why the registration should be revived.
• Proof of filing of all pending returns and proof of payment of tax, interest and late fees.
• Proof that the business is operating: bank statements, invoices, rent agreement, utility bill.
• PAN of the business or proprietor and identity of the authorised signatory.
• Any extra document asked for in Form REG-23.

Process and timeline

1. Collect the order and check the period for which returns are pending.
2. File all pending returns and pay the dues.
3. Log in and go to Services, Registration, Application for Revocation of Cancelled Registration.
4. Fill REG-21, upload documents, sign with DSC or EVC and submit. An ARN is issued.
5. The officer reviews. If clarification is needed, a notice in Form REG-23 is issued; reply within the time stated (commonly 7 working days).
6. The officer passes an order, usually within 30 days of the application: REG-22 for approval or REG-05 for rejection.
7. If approved, the GSTIN becomes active again and you must continue filing returns.

Timelines depend on completeness, complexity and authority processing.

Government fees, penalties and due dates

• No government fee applies to the revocation application.
• Late fees and interest on the pending returns must be paid before restoration. The late fee for a regular return is charged per day of delay with a cap, so the total depends on how many periods are pending.
• Window for REG-21: counted from the cancellation order; confirm the exact limit and extension rules for your case.
• Appeal against a rejection lies to the appellate authority under Section 107 of the CGST Act, within the time stated in that section.
• Amounts and dates above reflect public sources read in October 2026 and change with notifications, so Zenith confirms the current figures in your quotation.

Common mistakes

• Applying before filing all the pending returns.
• Missing the window because the cancellation order was in the portal notices and was never read.
• Submitting a short explanation without evidence that the business is running.
• Trying to revoke a voluntary cancellation.
• Ignoring the REG-23 query.
• Assuming the amnesty scheme still applies.
