TL;DR

When the tax department cancels your GST registration on its own motion (suo moto) under Section 29(2) of the CGST Act, you can apply for restoration by filing Form GST REG-21 online. Following statutory amendments under the Finance Act 2023 and Notification No. 38/2023-Central Tax, the standard deadline to file for revocation is 90 days from the date the cancellation order was served. The Joint or Additional Commissioner can extend this window by an additional 180 days on sufficient cause, giving a maximum outer window of 270 days. Before the tax officer can approve your application, you must file all pending returns with applicable tax, late fees, and interest. If this deadline lapses, your primary remedy shifts to an appellate remedy under Section 107 in Form GST APL-01.

Quick Answer: What is Form GST REG-21?

Form GST REG-21 is the statutory online application submitted on the GST Portal (www.gst.gov.in) by a registered taxpayer whose GSTIN was cancelled suo moto by the proper officer. It is governed by Section 30 of the CGST Act read with Rule 23 of the CGST Rules. This form allows businesses to remedy compliance defaults. It allows businesses to pay outstanding statutory dues. It allows businesses to restore their active GST status without losing their existing business identity or historical input tax credit.

Why GST Registration Gets Cancelled

The tax officer can cancel your GST registration on their own motion under Section 29(2) of the CGST Act. Common reasons include:

  • Non-filing of returns: If you fail to file GSTR-1 or GSTR-3B for a continuous period, the officer may issue a show-cause notice before cancelling.
  • Voluntary cancellation requested by the taxpayer: If you applied for voluntary cancellation, the officer cancels the registration.
  • Business discontinued: If the business has been wound up or the proprietor has died.
  • Transfer of business: If there is a change in ownership of the business.
  • Fraud or misrepresentation: If the registration was obtained through fraud, misrepresentation, or false information.

The Revocation Process: Rule 23 of the CGST Rules

Step 1: Check the Cancellation Order

First, check the date on the cancellation order (Form GST REG-19). This is important because the 90-day deadline runs from the date of service of this order.

Step 2: File All Pending Returns

Before you can file Form GST REG-21, you must file all pending GST returns. This includes:

  • GSTR-1 (outward supplies).
  • GSTR-3B (monthly summary return).
  • Any other applicable returns.

You must also pay any outstanding tax, late fees, and interest shown in those returns.

Step 3: Prepare Your Application

The Form GST REG-21 application must include:

  1. The details of the cancellation order (order number, date, and issuing officer).
  2. A self-declaration that all pending returns have been filed.
  3. Evidence of payment of all outstanding tax, interest, and late fees.
  4. A justification for why the cancellation should be revoked.
  5. Any other relevant supporting documents.

Step 4: Submit Form GST REG-21

  1. Log in to the GST portal at gst.gov.in.
  2. Navigate to Services → Registration → Application for Revocation of Cancellation.
  3. Enter your GSTIN and the cancellation order details.
  4. Upload the self-declaration and supporting documents.
  5. Submit using DSC (for companies and LLPs) or EVC.

Step 5: Officer Review

After submission, the application is assigned to the original officer who passed the cancellation order. The officer reviews the application and may:

  • Accept the revocation (Form GST REG-22 is issued — GSTIN is restored).
  • Reject the revocation (Form GST REG-23 is issued).
  • Request additional information (Form GST REG-24).

Step 6: Restoration

If approved, Form GST REG-22 is issued. Your GSTIN is restored to active status. All your historical ITC balance is preserved.

The 90-Day Deadline: Key Rule

The deadline to file Form GST REG-21 is 90 days from the date of service of the cancellation order. This is a strict statutory deadline. Missing it is fatal to the application.

Extension up to 180 Days

Under Section 30 of the CGST Act (as amended by the Finance Act 2023), the Joint or Additional Commissioner can extend the deadline by an additional 180 days on sufficient cause shown. This means the maximum window is 270 days from the date of service of the cancellation order.

To apply for an extension:

  1. File Form GST REG-21 within the initial 90 days.
  2. In the form, clearly state the reasons for the delay.
  3. Submit supporting evidence (hospitalisation records, natural disaster proof, etc.).
  4. The officer has discretion to grant or refuse the extension.

After 270 Days

If 270 days have passed and you have not filed Form GST REG-21, the revocation option is closed. Your only remaining remedy is to file an appeal under Section 107 of the CGST Act.

Common Mistakes to Avoid

Mistake 1: Missing the 90-Day Deadline

The 90-day deadline is strictly enforced. If you miss it, you cannot file REG-21. Your only option is an appeal under Section 107. An appeal requires a pre-deposit of 10% of the tax amount (or ₹200 crore, whichever is lower). This is far more expensive than revoking the registration.

Mistake 2: Filing REG-21 Without Filing Pending Returns

The GST portal will not accept your REG-21 application if you have pending returns. File all GSTR-1 and GSTR-3B returns before submitting REG-21.

Mistake 3: Not Paying Outstanding Tax and Interest

Even if you file pending returns, you must also pay the tax, interest, and late fees shown in those returns. Filing returns without payment is not sufficient.

Mistake 4: Applying for Revocation When Registration Was Obtained Through Fraud

If your GST registration was cancelled because it was obtained through fraud, misrepresentation, or false information, you cannot revoke it. The registration must be cancelled and you must apply for fresh registration. Revocation is not available in fraud cases.

Mistake 5: Assuming ITC Balance Is Protected After Cancellation

If your GST registration is cancelled and you do not revoke it within the deadline, your accumulated input tax credit lapses. It cannot be transferred to a new registration.

After Restoration: Next Steps

Once your GSTIN is restored (Form GST REG-22 issued):

  1. Check your ITC balance: Verify that your input tax credit balance is intact.
  2. File pending returns: If you filed pending returns to support the revocation, ensure they are processed.
  3. Update GST portal profile: Ensure all details are current.
  4. Set return filing reminders: To avoid future cancellations, set up monthly reminders for GSTR-1 and GSTR-3B filing.

Appealing a Rejection of Revocation

If the officer rejects your REG-21 application (Form GST REG-23 issued), you can:

  1. Appeal to the Appellate Authority under Section 107: File Form GST APL-01 within 90 days of the rejection order. A pre-deposit of 10% of the tax amount is required.
  2. Apply for a condonation of delay if the appeal is late: Under Section 117 of the CGST Act, you can apply to the Appellate Authority for condonation of delay.
