A registration cancelled by the officer, most often for returns not filed, stops a business from charging tax and its customers from taking credit. The business usually finds out when an invoice is rejected or a customer’s credit fails to match. The way back is an application for revocation. It has a deadline, it has a precondition that catches many applicants, and it imposes obligations after it succeeds.
The law is in section 30 of the CGST Act, introduced in Registration, and What Goes Wrong. The procedure is in rule 23 of the CGST Rules.
Only a cancellation by the officer can be revoked
Section 30(1) gives the right to “any registered person, whose registration is cancelled by the proper officer on his own motion”. Rule 23(1) uses the same words. A registration cancelled on the person’s own application in FORM GST REG-16 falls outside both. The portal’s FAQ lists that case among those that “cannot apply for revocation”, along with cancellation at the request of a legal heir. UIN holders and GST practitioners are also excluded.
Neither the Act nor the rules provide a way to reopen a registration cancelled on application. A person in that position who becomes liable again applies for a new registration under section 25, as described in Applying for GST Registration. If the person disputes the cancellation order itself, the remedy is an appeal.
Ninety days, extendable by up to one hundred and eighty
Section 30(1) originally fixed thirty days from service of the cancellation order. From 1 October 2023, section 141 of the Finance Act, 2023 replaced that with “such manner, within such time and subject to such conditions and restrictions, as may be prescribed”. It was brought into force by Notification No. 28/2023-Central Tax dated 31 July 2023. The Commissioner’s power to extend, in the old proviso, was omitted at the same time.
The time limit is now in rule 23(1), as amended by Notification No. 38/2023-Central Tax dated 4 August 2023, “with effect from the 1st day of October, 2023”. The application must be made “within a period of ninety days from the date of the service of the order of cancellation of registration”. The first proviso allows a further period:
“such period may, on sufficient cause being shown, and for reasons to be recorded in writing, be extended by the Commissioner or an officer authorised by him in this behalf, not below the rank of Additional Commissioner or Joint Commissioner, as the case may be, for a further period not exceeding one hundred and eighty days”
The portal’s manual counts the days from “the date on which Cancellation Order was passed”, not from service. Up to 90 days, the application goes to the jurisdictional officer. From 91 to 270 days, the portal warns the applicant and asks for a reason for condonation of delay. The application then goes to the competent authority, and reaches the jurisdictional officer only if the delay is condoned. After 270 days the portal refuses the application, with a message pointing to an appeal before the Appellate Authority.
Since 1 November 2024, a second proviso to section 30(2), inserted by section 121 of the Finance (No. 2) Act, 2024, makes revocation itself “subject to such conditions and restrictions, as may be prescribed”. Rule 23 contains the conditions.
Returns and dues first
The second proviso to rule 23(1) is the precondition:
“no application for revocation shall be filed, if the registration has been cancelled for the failure of the registered person to furnish returns, unless such returns are furnished and any amount due as tax, in terms of such returns, has been paid along with any amount payable towards interest, penalty and late fee in respect of the said returns”
In practice, the returns to the date of cancellation are filed and the tax, interest and late fee on them are paid before REG-21 is opened. The portal’s FAQ for cancellations says returns for periods while the GSTIN was active can still be filed after cancellation.
Aadhaar authentication
Rule 10B requires Aadhaar authentication before filing REG-21. It applies to the proprietor, a partner, the karta, the managing or a whole-time director, a committee member or trustee as the case may be, and the authorised signatory. A person without an Aadhaar number furnishes the enrolment ID slip with a bank passbook bearing a photograph, a voter identity card, a passport or a driving licence. The portal will not open the revocation form until Aadhaar is authenticated or e-KYC documents are uploaded.
Filing REG-21 and what the officer does
The applicant logs in with the old credentials. The application is at Services > Registration > Application for Revocation of Cancelled Registration. FORM GST REG-21 asks for the cancellation order number and date, the reason for cancellation, the last return filed with its ARN, and the reasons for revocation. Fuller reasons can be attached. The application is verified by DSC or EVC, and the portal issues an ARN.
Rule 23(2) to (4) then provides:
- If the officer is satisfied there are sufficient grounds, he revokes the cancellation by an order in FORM GST REG-22, within thirty days of the application.
- If he proposes to reject it, he must first issue FORM GST REG-23, a notice to show cause why the application should not be rejected.
- The applicant replies in FORM GST REG-24 within seven working days of service.
- The officer decides within thirty days of the reply, by REG-22 or by a rejection order in FORM GST REG-05.
Section 30(2) adds that the application “shall not be rejected unless the applicant has been given an opportunity of being heard”.
The portal’s FAQ says that on approval the GSTIN becomes active “with effect from the effective date of cancellation”. Any composition registrations on the same PAN are converted to normal. On rejection the GSTIN stays inactive.
If the application is rejected
A REG-05 rejection is an order under the Act. It can be appealed under section 107 “within three months from the date on which the said decision or order is communicated”. The Appellate Authority may allow “a further period of one month” on sufficient cause. The procedure is in Appeals and Pre-Deposit. An appeal against the original cancellation order follows the same section, and is the route left once the 270 days have passed.
After revocation: thirty days to bring returns up to date
Two further provisos to rule 23(1) apply once revocation is granted. All returns “for the period from the date of the order of cancellation of registration till the date of the order of revocation” must be filed within thirty days of the revocation order. Where cancellation was retrospective, the period runs from “the effective date of cancellation”. Rule 21(ga), inserted by Notification No. 12/2024-Central Tax, makes a breach of either proviso a ground for cancelling the registration again.
Credit for the gap is protected. Under section 16(6), a person whose cancellation is revoked may take credit on invoices that were not already time-barred at cancellation. The credit is taken in a return filed by the usual section 16(4) date, or in a return for the cancellation period filed within thirty days of the revocation order, whichever is later. The conditions for credit are in Input Tax Credit: the Conditions in Section 16(2).
Documents and declarations
| Document | Who provides it | Source |
|---|---|---|
| Pending returns filed, and tax, interest, penalty and late fee paid | Registered person | Rule 23(1), REG-21 instructions |
| Aadhaar authentication, or enrolment ID with a photo identity document | Persons listed in rule 10B | Rule 10B, portal manual |
| Cancellation order number and date | Registered person | REG-21 |
| Reasons for revocation, with supporting documents | Registered person | REG-21 |
| Reasons for condonation of delay (days 91 to 270) | Registered person | Portal manual |
| Verification that the information is “true and correct” | Authorised signatory | REG-21 |
Neither rule 23 nor REG-21 requires geocoding or a physical verification for revocation. The officer’s general power under rule 25(1) to verify premises “after the grant of registration” is unaffected. That verification is reported in FORM GST REG-30 with photographs and the site’s latitude and longitude. The portal manual’s revocation pages state no file-size limit.
One discrepancy is worth knowing. The instructions printed in FORM GST REG-21, last amended in 2021, still refer to “thirty days” and to an extension under the proviso to section 30(1). Both have been overtaken by the 2023 amendments. Rule 23 governs.
