If your GST registration is shown as cancelled, start with the official cancellation order. The next step depends on who initiated cancellation, the stated ground, the order's service date and effective date, and whether required returns or dues remain outstanding. There is no single reactivation process for every case.
This guide focuses on revocation after a proper officer cancelled a registration on the officer's own motion under the central CGST framework. Cancellation requested by the taxpayer follows a different route. State and Union territory GST provisions and portal workflows should also be checked for the registration concerned.
Read the notice and cancellation order first
Use the official GST portal to retrieve the show-cause notice, your reply, hearing records, final order and related portal messages. Save copies. Note the GSTIN, issuing authority, provision and ground cited, date the order was served, effective date stated in the order, and any reply or appeal deadline. Preserve the returns, ledgers, challans, invoices and correspondence that relate to the stated ground.
Section 29 of the Central Goods and Services Tax Act, 2017 provides for cancellation in specified circumstances, including on a registered person's application and by the proper officer. Before an officer cancels a registration under section 29(2), the Act provides an opportunity of being heard. Cancellation does not by itself remove tax or other obligations for periods before the effective date. A retrospective date may affect returns and transaction records, so do not treat it as a clerical detail.
| Check in the order | Why it matters |
|---|---|
| Who initiated cancellation | Rule 23 revocation is for an officer-initiated cancellation. |
| Ground and cited provision | The reason may affect what must be fixed before applying. |
| Date the order was served | The central rule 23 period runs from service of the order. Keep evidence of service. |
| Effective date | A retrospective date can affect prior-period obligations and records. |
| Returns, tax, interest, penalty or late fee | Return-default cases have pre-filing requirements under rule 23; additional returns are due after revocation. |
When rule 23 revocation may apply
Section 30 of the CGST Act and rule 23 of the CGST Rules, 2017 provide a revocation route where the proper officer cancelled the registration on the officer's own motion. Rule 23 does not establish a general revocation route for a cancellation requested by the taxpayer. For a taxpayer-requested cancellation, review the order and consider with a GST professional whether an appeal, correction or another application fits the facts.
Rule 23 makes a FORM GST REG-21 application subject to rule 10B's Aadhaar-authentication condition for eligible registered persons. The central application period is 90 days from service of the cancellation order. On sufficient cause, and for reasons recorded in writing, the Commissioner or an authorised officer not below Additional Commissioner or Joint Commissioner may extend that period by up to a further 180 days. An extension is discretionary, not automatic.
If cancellation followed failure to file returns, the relevant pending returns and amounts due must be addressed before applying: rule 23 bars filing until those returns are furnished and tax, interest, penalty and late fee due in respect of them are paid. Revocation also starts a separate 30-day return window. Returns due for the period from the cancellation order to the revocation order must be furnished within 30 days after the revocation order. If cancellation was retrospective, returns for the period from the effective cancellation date to the revocation order must also be furnished within that 30-day window. Check which periods apply to the order and have the return position reviewed promptly.
The 90-day text comes from Notification No. 38/2023-Central Tax, which states that the amendment takes effect on 1 October 2023. The CBIC tax-information page displays the amended wording but its amendment-history note gives a conflicting effective date. Use the Gazette text for the effective date and ask a GST professional to verify the version applicable to your case. Older material describing a 30-day period with a 90-day extension reflects earlier wording and should not be used as the current central rule 23 deadline.
Keep the recent rule changes in their lane
Notification No. 05/2026-Central Tax, published in the Gazette on 27 October 2026, makes changes to the CGST Rules with different commencement dates. Its substitution of rule 20 for cancellation requested by a taxpayer takes effect on 1 November 2026. The notification also inserts rule 23A for specified system-based cancellations from 1 April 2027. These provisions concern different cancellation routes and dates; they do not turn rule 23 into a general remedy for every cancelled registration. Check the Gazette and the rule in force for the event and date that apply to you.
Respond, apply or appeal with the record in view
If you have received a show-cause notice, respond by the date stated in it and address the specific ground with relevant supporting records. If an order has already been made, a GST professional can assess whether revocation, appeal under section 107, correction or more than one step is appropriate. Any appeal is subject to statutory requirements and deadlines; this guide does not calculate them.
Submitting an online application does not itself restore a registration or decide a challenge. Wait for the official order or status record before representing that the registration is active. Until then, get advice on invoicing, tax collection, returns, input-tax credit, e-way bills and customer or supplier records for the affected period. Do not backdate documents or change records to fit a preferred effective date.
The central sources describe the legal framework; they do not confirm what a live taxpayer account will accept or whether an individual qualifies. Verify current portal instructions and any applicable State or Union territory provisions. Keep passwords and one-time codes private, and independently verify any request for payment or credentials.
For legal teams that coordinate these matters across staff, Gotham's practice-area workflows and source-linked legal workflows describe ways to organize recurring tax and regulatory work. Its legal case management approach covers intake, matter records, documents, source-linked events and reviewed status reporting. These tools support internal organization; official GST portals and orders remain authoritative for filing and registration status. To discuss whether this fits a team's process, contact Gotham.

Questions about GST registration cancellation
How long do I have to apply for revocation of an officer-initiated GST cancellation?
Rule 23 of the central CGST Rules currently provides 90 days from service of the cancellation order. A further extension of up to 180 days may be granted for sufficient cause by the specified senior authority. It is not automatic. Confirm service and applicable State or Union territory provisions with a GST professional.
Can I use rule 23 if I asked to cancel my GST registration?
Rule 23 is for a cancellation made by the proper officer on the officer's own motion. It is not a general revocation route for a taxpayer-requested cancellation. Have the order and relevant dates reviewed to identify an appropriate next step.
Do I need to file returns before applying?
If cancellation was for failure to furnish returns, rule 23 requires those returns and the tax, interest, penalty and late fee due in respect of them to be paid before an application for revocation. After revocation, returns for the period from the cancellation order to revocation are due within 30 days. The same 30-day window applies from the effective date when the cancellation was retrospective. Check your ledger and the current rule with a GST practitioner.
Does filing FORM GST REG-21 restore my GST registration?
No. Filing is an application, not proof that it has been allowed. Rely on the official order and status record before treating the registration as restored.
Does this guide cover system-based cancellation or State GST rules?
It focuses on the central rule 23 process for officer-initiated cancellation. Different provisions apply to other routes, and State or Union territory rules and current portal steps must be checked for the case.
This article is general information about central GST rules, not tax or legal advice. GST procedures, portal functions and State or Union territory provisions may differ or change. Have a qualified Indian GST professional review the order, dates and facts before acting.
