REG-21 is the form for revoking a GST registration that the officer cancelled on their own motion. File it within 90 days of the cancellation order being served; the Commissioner can extend that by up to 180 more days for sufficient cause. If the cancellation was for non-filing, the pending returns, tax, interest and late fee must be cleared first. GST registration cancellation can be voluntary or initiated by the GST officer, and the correct process depends on who cancelled the registration, why it was cancelled, the effective date and the taxpayer's pending returns and dues. CorporateWalla provides support for cancellation applications, backlog reconciliation and revocation of officer-cancelled registrations, subject to the facts of the case.
Important: Revocation is not available for a registration voluntarily cancelled by the taxpayer. Revocation under Section 30 and Rule 23 is for cancellation by the proper officer on their own motion.
REG-21 is the application to revoke a GST registration cancelled by the officer. You file it within 90 days of the date the cancellation order (REG-19) is served on you, or within a further 180 days if the Commissioner extends the time for sufficient cause. If the cancellation was for not filing returns, you cannot even file REG-21 until those returns are filed and the tax, interest, penalty and late fee on them are paid. The officer then has 30 days to revoke in REG-22 or, after a REG-23 show-cause notice and your REG-24 reply, reject in REG-05.
| Who cancelled it? | Route | Form |
|---|---|---|
| The officer, on their own motion (for example, continued non-filing of returns) | Revocation under Section 30 / Rule 23 | REG-21 |
| You, on your own application | No revocation. Apply afresh if you need GST again | REG-01 |
| The officer, and you dispute the grounds of the order itself | Appeal against the cancellation order (within the appeal time limit) | APL-01 |
A monthly filer stops filing after March 2026. The officer issues a show-cause notice and cancels the GSTIN by an order served on 10 September 2026, with effect from 1 April 2026.
In practice the professional work is two batches of GST return filing wrapped around one application. That is why we quantify the backlog before quoting.
Illustrative scenario. Interest and late fee depend on the actual tax, dates of payment and any late-fee waiver notified for the period.
If the officer has only issued a show-cause notice so far, reply to it before the order is passed: see GST notice reply. If revocation is rejected, the order can be challenged through a GST appeal.
| Situation | Usual route |
|---|---|
| Business closed / no longer liable | Voluntary cancellation |
| Transfer, merger or change in constitution requiring cancellation | Cancellation with applicable supporting details |
| Officer cancelled registration | Revocation may be available, subject to Section 30 / Rule 23 |
| Voluntary cancellation already approved | Fresh registration may be required if GST registration is needed again |
| Cancellation order disputed | Consider appeal / other appropriate remedy after reviewing the order |
The first question should always be: Was the GSTIN cancelled by you or by the department?
A registered person seeking cancellation applies electronically through the GST portal in the prescribed cancellation form and provides the reason, effective date and required stock/liability details.
Common reasons include:
The GST portal's current cancellation workflow requires the taxpayer to select the reason, enter the effective date and provide applicable stock and tax-liability information. The application is electronically signed and generates an ARN for tracking.
Cancellation does not automatically erase past tax obligations. Returns, tax, interest, penalties and other statutory liabilities for periods covered by the registration can remain payable.
A final-return / post-cancellation compliance review should also be considered where applicable.
The GST officer may initiate cancellation in circumstances specified by the CGST Act and Rules, including prescribed non-compliance.
Where cancellation proceedings are initiated, the taxpayer may receive a show-cause notice and should respond within the period stated in the notice. GST notice support can help with the response.
A taxpayer should not assume that every cancellation notice is automatically final. The notice, grounds, return history and supporting evidence should be reviewed before deciding whether to contest the proposed cancellation or allow the registration to be cancelled.
Where the proper officer has cancelled a registration on their own motion, the taxpayer may apply for revocation under Section 30 of the CGST Act read with Rule 23, subject to the statutory conditions.
The ordinary period for applying for revocation is 90 days from the date of service of the cancellation order. The Commissioner, or an officer authorised by him not below the rank of Additional or Joint Commissioner, may extend it by a further period of up to 180 days for sufficient cause, with reasons recorded in writing. That gives an outer limit of 270 days from service. This has been the position since 1 October 2023 (Notification No. 38/2023 - Central Tax); before that the base period was 30 days.
| Stage | Form | Time limit (Rule 23) |
|---|---|---|
| Officer cancels registration on own motion | REG-19 (cancellation order) | Day 0 = date the order is served |
| You apply for revocation | REG-21 | Within 90 days of service; up to 180 days more if the Commissioner extends |
| Officer revokes the cancellation | REG-22 | Within 30 days of receiving REG-21 |
| Officer proposes to reject: show-cause notice | REG-23 | Issued before any rejection |
| Your reply to the show-cause notice | REG-24 | Within 7 working days of service of REG-23 |
| Officer decides after your reply | REG-22 or REG-05 (rejection) | Within 30 days of receiving REG-24 |
| Returns for the period the GSTIN was cancelled | GSTR-1 / GSTR-3B | Within 30 days of the REG-22 revocation order |

If the taxpayer voluntarily surrendered GST registration, the Rule 23 revocation mechanism does not apply. If GST registration is required again, a fresh-registration route may need to be considered.
Where cancellation occurred because of non-filing of returns, revocation has an important precondition: the applicable pending returns must be furnished and the tax, interest, penalty and late fee payable in respect of those returns must be dealt with as required under the GST law.
The amount of backlog can therefore be more significant than the professional fee.
CorporateWalla can first prepare a GST backlog assessment showing:
Rule 23(1) makes a revocation application subject to Rule 10B, which requires Aadhaar authentication. On the GST portal, a taxpayer whose Aadhaar is not already authenticated must complete it, or upload e-KYC documents, before REG-21 can be filed. The exact portal requirement should be checked for the taxpayer category and current GSTN workflow before filing.
Aadhaar authentication is not a substitute for satisfying the substantive conditions for revocation.
Determine whether voluntary cancellation is appropriate and identify the proposed effective date.
Review inputs, semi-finished/finished goods and capital goods and the applicable tax consequences at cancellation.
Prepare and file the cancellation application and supporting information where included in scope.
For officer-initiated cancellation, review the notice/order and identify whether a response, revocation application or appeal should be considered.
Identify pending returns and reconcile the books, GST returns and available portal data before filing.
For eligible officer-cancelled registrations, prepare the revocation application, explanation and supporting documents.
After restoration, review returns and other compliance obligations that became due during the relevant period and agree a filing plan.

Government fee — paid by you at actuals
Nil on the revocation application itself — Form GST REG-21 carries no government charge, and neither does REG-16 or GSTR-10. What you do pay the government is the tax, interest, penalty and late fee on every pending return up to the cancellation date, all at actuals. For someone who stopped filing eighteen months ago that backlog is the real cost of getting back in, and it is usually much larger than the professional fee. We quantify it before you commit.
Every price above is a professional fee, excluding GST and government charges. 50% upfront, 50% on delivery.
All fees and charges listed are indicative only and do not constitute a binding offer. Final amounts may vary depending on the volume of work and the complexity involved.
Revocation under Section 30 and Rule 23 is for cancellation by the proper officer on their own motion; it is not available for a registration voluntarily cancelled by the taxpayer.
Review the notice/order and identify whether a response, revocation application or appeal should be considered.

Check the Aadhaar authentication requirement for the taxpayer category under the current GSTN workflow before filing.
Prepare the revocation application, explanation and supporting documents.
File the revocation application for the eligible officer-cancelled registration.
Respond within the stated period if the officer issues REG-23 on the application.
Track the officer's order on the application; a rejection order and its grounds should be reviewed for the available remedy.
After restoration, review returns and other compliance obligations that became due during the relevant period and agree a filing plan.
Tell us your requirement, a CA will call you in 30 minutes.
Whether voluntary cancellation is appropriate is determined, the effective date and stock/liability position are reviewed, and the cancellation application is prepared and filed where included in scope.
