GST Cancellation Order: Filing Revocation Application REG-21

Your GSTIN has been cancelled by a written order and the portal now refuses to accept returns. The first thing to establish is whether the order rests on a curable ground, because most cancellations for non-filing of returns can be undone through GST cancellation revocation under Section 30 of the CGST Act, 2017. The clock, though, runs from the date the order was served on you, not from the date you noticed it. This guide covers how the order comes to be passed, how to file FORM GST REG-21, what evidence makes the application credible, and what is left if the officer rejects it.

Why the GST department cancelled your registration

Section 29(2) of the CGST Act, 2017 does not leave cancellation to the officer's mood. It can be ordered only on the grounds listed there: contravention of the Act or the rules, failure to furnish returns for the prescribed period, a composition taxpayer's failure to file for three consecutive tax periods, voluntary surrender by the taxpayer, or registration obtained by fraud, wilful misstatement or suppression of facts. Rule 21 of the CGST Rules fixes the return-default threshold — six continuous months for a regular taxpayer, three consecutive tax periods for a composition dealer.

The procedure sits in Rule 22. A show-cause notice in FORM GST REG-17 sets out the ground and gives you seven working days to reply in FORM GST REG-18. If the reply satisfies the officer, proceedings are dropped in FORM GST REG-20. If there is no reply, or the reply does not hold, the officer passes a cancellation order in FORM GST REG-19 with reasons recorded. That order is uploaded on the portal, usually under Additional Notices, and it states the effective date of cancellation.

Read that effective date carefully. For cancellations on the fraud ground under Section 29(2)(e), the order can operate retrospectively. In the ordinary non-filing case it usually takes effect from the date of the order.

Suspension is not the same as cancellation

Rule 21A lets the officer suspend a registration while cancellation proceedings are pending, during an enquiry, or where a comparison of GSTR-1, GSTR-3B and e-way bill data throws up a discrepancy. Suspension is a holding measure. The GSTIN stays on the register, but return filing and most portal functions are blocked until the position is regularised.

Do not treat a suspension as a warning you can sit on. If the underlying issue is unpaid returns, the suspension converts into cancellation once the officer passes the order, and the revocation clock starts on service of that order. Reply to the REG-17 within the seven working days, even if the reply only buys time while the returns are being readied.

GST cancellation revocation: filing FORM GST REG-21 within the window

Section 30(1) allows the proper officer to revoke a cancellation on an application by the taxpayer, and Section 30(2) bars an application made after the prescribed period. Rule 23 of the CGST Rules prescribes that period: 90 days from the date of service of the cancellation order, with provision for the Commissioner to extend it on sufficient cause being shown.

The form is FORM GST REG-21, available on gst.gov.in under Services → Registration, and it appears only where a cancellation order is on record. One condition catches most applicants. Where the registration was cancelled for non-filing, the application can be filed only after every return due up to the date of cancellation has been furnished, and the tax, interest, penalty and late fee have been paid. The portal enforces this: the REG-21 option stays disabled until the returns are cleared.

That creates a practical deadlock. Once cancellation takes effect, the portal often blocks return filing for the pre-cancellation months. The way out is a written request to the jurisdictional officer to enable filing for those periods, with copies of the cancellation order and a month-wise dues statement. Officers can and do open the window. What does not work is filing the REG-21 first and hoping the returns can follow.

The officer is expected to dispose of the application within 30 days, either by revoking the cancellation in FORM GST REG-22 or by rejecting it. On revocation the cancellation order is withdrawn and the registration is restored from the original date. That matters for input tax credit in the intervening months and for the continuity of invoices already issued. Returns for the period between cancellation and restoration then become due.

Grounds and documents that support restoration

The application succeeds or fails on one question: have the grounds for cancellation ceased to exist? For a non-filing cancellation, the answer is the filed returns and the paid challans. For an address-based cancellation, it is proof that the principal place of business exists — a registered rent deed or lease, an electricity bill, a no-objection certificate from the landlord, a municipal khata or property tax receipt, and photographs of the signage.

Where the cancellation followed no reply to a REG-17, attach the reply you should have filed. Address each ground in the order by paragraph. A two-page note that quotes the order number, the ground and the document answering it does more than a weighty bundle.

Before you file, confirm these

• You have the exact date of service of the cancellation order, taken from the Additional Notices tab

• Every return due up to the date of cancellation is filed and the acknowledgement is saved

• Tax, interest, penalty and late fee for those returns are paid, with challans downloaded

• The application is within 90 days, or carries a written request for condonation of delay

• Premises documents match the address on the registration, down to the door number and PIN code

• Bank account and authorised signatory details on the portal are current

• Your covering note answers each ground in the order, one by one

How it plays out in practice

A Coimbatore trader dealing in pumps and spares missed six GSTR-3B returns for October 2024 to March 2025 after his accountant left and the portal credentials were misplaced. A REG-17 went unanswered, and the officer cancelled the registration by order in FORM GST REG-19 dated 12 May 2025, served on the portal the same day. The proprietor learnt of it only in July, when a buyer's accounts team refused an invoice.

The 90-day window closed on 10 August 2025. He filed on 5 August. Because the portal would not accept the six returns, he wrote to the jurisdictional officer on 18 July, enclosing the cancellation order and a month-wise dues statement; filing was enabled within a week. He cleared the returns and paid tax of ₹1,86,400 with interest and late fee as computed on the portal, then filed FORM GST REG-21 with the return acknowledgements, challans, the registered lease deed, an electricity bill and a two-page note answering the single ground in the order. The officer issued FORM GST REG-22 on 26 August 2025. The GSTIN was restored, and returns for June to August 2025 became due immediately.

If the revocation application is rejected

A rejection comes as an order recording reasons. Sometimes the reason is substantive, such as the officer not being satisfied that the premises exist. Often it is mechanical, because the officer has merely repeated the original ground. Read it before reacting. If it is factually wrong — it says returns were not filed when they were — a written representation with the acknowledgements attached sometimes gets the order revised. The statute provides no formal review, so do not rely on that route alone.

Appeal to the Appellate Authority

The remedy is an appeal under Section 107 of the CGST Act, 2017, filed within three months of communication of the order, with one further month available if the appellate authority is satisfied there was sufficient cause for the delay. The appeal is filed electronically in FORM GST APL-01 with the order and the grounds. The pre-deposit under Section 107(6) is linked to the tax in dispute; where the order only cancels the registration and quantifies no tax, the demand is nominal, but confirm the figure with the appellate authority's office before paying it.

Do not let the appeal lull you. The cancellation keeps operating while the appeal is pending, so invoices, e-way bills and your buyers' input tax credit all suffer in the meantime.

Fresh registration and other compliance

A fresh application against the same PAN is possible in principle, but the portal and the jurisdictional officer will usually want the earlier cancellation resolved first, particularly where the ground was non-filing. Weigh the two routes on continuity: buyers and contracts may need the same GSTIN, and the intervening credit may be worth more than the cost of the revocation process.

Cancellation does not erase liability for the period before it. The department can still raise demands for those months, and a final return in FORM GSTR-10 is due within three months of the cancellation date or the order, whichever is later, under Section 45. Where you intend to pursue revocation, take advice before filing the final return, since it is a declaration that the business has closed under that GSTIN.

Common mistakes that sink an application

Filing the REG-21 before the pending returns are cleared is the most frequent error, and it produces a rejection within days. The second is missing the 90-day window because nobody checked the Additional Notices tab; the portal sends no separate reminder for a cancellation order. The third is a mismatch between the registered address and the documents attached. The fourth is paying tax but not late fee, or the reverse — the portal will block the application for a small shortfall.

Keep, in one folder: the cancellation order with its date of service, all return acknowledgements, challans, premises documents, the covering note filed with the REG-21, and every communication from the officer. If you end up before the appellate authority, that folder is your case.

If your registration has already been cancelled, open the Additional Notices tab today and note the date of service. If 90 days have not run out, clear the pending returns and file FORM GST REG-21 this week.
