Quick Answer: Revocation of cancellation of GST registration is applied for in FORM GST REG-21 on the GST portal, within 90 days of the cancellation order. The Commissioner can extend that by up to 180 days, so 270 days is the outer limit. It works only if the officer cancelled your GSTIN, and pending returns and dues come first.
If your GST registration was cancelled by the tax officer, revocation of cancellation of GST registration is how you get the same registration back. Revocation of GST registration isn't automatic; you have to apply. Before 1 October 2023 the window was only 30 days, so guides quoting 30 days are out of date.

Who can apply for revocation of cancellation of GST registration?
You can apply only if the proper officer cancelled your registration on his own motion, called a suo motu cancellation. That's what Section 30 of the Central GST (CGST) Act and Rule 23 of the CGST Rules say.
It follows a show cause notice, and a GST registration cancelled this way most often traces back to returns not filed. If you asked for cancellation yourself in FORM GST REG-16, there's nothing to revoke; you'll need a fresh registration instead. For how cancellation itself works, see our guide to the GST cancellation process.
What is the GST revocation time limit?
You have 90 days from the date the cancellation order is served on you. Notification No. 38/2023-Central Tax, dated 4 August 2023, set this from 1 October 2023.
| When you apply | What happens |
|---|---|
| Day 1 to day 90 | File REG-21 normally; it goes straight to your officer |
| Day 91 to day 270 | File REG-21 with a reason for the delay; it needs an extension first |
| After day 270 | The portal blocks REG-21; appeal or register again |
The extra 180 days are granted by the Commissioner, or an officer he authorises not below Additional or Joint Commissioner, for sufficient cause recorded in writing. A late application goes to that authority first and reaches your officer only if the delay is condoned. The portal counts from the date the order was passed, so don't cut it fine.
What must you do before applying for revocation?
If your registration was cancelled for not filing returns, you must file every pending return first. You must also pay the tax due on them, with interest, penalty and late fee. The first proviso to Rule 23 of the CGST Rules bars the application until then.
Your to-do list before filing:
- File all returns pending up to the cancellation date.
- Pay the tax shown in them, plus interest and late fee.
- Complete Aadhaar authentication, or upload e-KYC documents, for the GSTIN. Rule 10B requires this for REG-21.
After revocation, returns for the gap between cancellation and revocation are due within 30 days of the revocation order.
How do you file GST REG-21 on the GST portal?
You log in with your old GST credentials and fill a short online form. The GST portal's revocation manual sets out these steps.
- Log in at gst.gov.in with the username and password you used before.
- Go to Services > Registration > Application for Revocation of Cancelled Registration.
- Enter the reason for revocation. If you're past 90 days, also enter the reason for the delay.
- Attach supporting documents using Choose File.
- Tick the verification box, pick the authorised signatory and enter the place.
- Submit with a digital signature certificate (DSC) or an electronic verification code (EVC).
An Application Reference Number (ARN) reaches your registered email and mobile within about 15 minutes, so you can track the application with your ARN. If the officer agrees, he revokes the cancellation in FORM GST REG-22 within 30 days.
What if your GST revocation is rejected?
The officer can't simply refuse. He must first send a show cause notice in FORM GST REG-23, asking why your application shouldn't be rejected.
- Reply in FORM GST REG-24 within seven working days, with proof.
- Wait for the decision. The officer must decide within 30 days of your reply, by REG-22 or a rejection order in FORM GST REG-05.
- Appeal if rejected. Under Section 107 of the CGST Act, appeal to the Appellate Authority in FORM GST APL-01 within three months. One more month may be allowed for sufficient cause.
Should you revoke the cancellation or register again?
Revoke the cancellation if the officer cancelled it and you're within 270 days; otherwise, register for GST again online on the GST portal. A fresh application is the only route after a voluntary cancellation, or once revocation and appeal are both closed.
| Your situation | Best route |
|---|---|
| Officer cancelled, within 90 days | File REG-21 now |
| Officer cancelled, day 91 to 270 | File REG-21 with a reason for the delay |
| Officer cancelled, past 270 days | Appeal, or apply for a fresh registration |
| You cancelled it yourself | Fresh registration |
A fresh registration starts again from Part A of the application, with the usual documents for GST registration. The government charges nothing for it; see what GST registration costs for the full picture.
