How registration-cancellation proceedings work
Where the proper officer has reasons to cancel your registration under Section 29(2), he must issue a show cause notice in Form REG-17, giving you 7 working days to reply in Form REG-18 – and the proviso to Section 29(2) guarantees an opportunity of being heard before cancellation. If your reply is found satisfactory, the proceedings are dropped by an order in Form REG-20. Otherwise, a cancellation order in Form REG-19 can follow within 30 days of the reply.
Meanwhile, under Rule 21A(2), the registration usually stands suspended from the date of the notice: you cannot issue tax invoices or make taxable supplies, and no refunds are processed. The officer has express power under the proviso to Rule 21A(4) to revoke the suspension at any time during the proceedings – which is why the reply generated here always asks for it, on business-continuity and livelihood grounds.
Grounds on which registration can be cancelled
| Ground | Source | Core defence |
|---|---|---|
| Returns not filed – 6 months (monthly) / two tax periods (QRMP) | s.29(2)(c) + Rule 21(h)/(i) | File ALL pending returns + dues: drop of proceedings becomes MANDATORY (proviso to Rule 22(3)) |
| Composition return not filed for 3 months beyond due date | s.29(2)(b) | Same mandatory-drop route |
| Business not conducted from declared place / found non-existent | Rule 21(a) | Ownership/rent proof, utility bills, photographs, books; Rule 25 verification defects |
| Invoice issued without supply | Rule 21(b) | Movement evidence: e-way bills, transport, weighbridge, bank trail |
| Registration obtained by fraud / misstatement / suppression | s.29(2)(e) | SCN must specify WHAT was suppressed – bare recital is bad in law |
| Voluntary registration – business not commenced in 6 months | s.29(2)(d) | Evidence of commencement steps or reasonable cause |
| GSTR-1 outward supplies exceed GSTR-3B | Rule 21(f) | Reconciliation – see our DRC-01B tool |
| ITC availed in violation of Section 16 / Rule 86B violation | Rule 21(e)/(g) | Documentation of eligibility; ledgers |
| Bank details not furnished (Rule 10A) | Rule 21(d) | Comply – suspension stands deemed-revoked on compliance |
If the registration is already cancelled
Apply for revocation in Form REG-21 within 90 days of service of the cancellation order (extendable by up to a further 180 days by the competent authority on sufficient cause) – but only after filing all pending returns and paying the dues. The officer must dispose of the application within 30 days. An appeal under Section 107 within three months is the parallel remedy, particularly against retrospective cancellations – the Delhi High Court has repeatedly held that cancellation with retrospective effect requires recorded reasons and cannot be mechanical.
Frequently asked questions
Can I continue business while the REG-17 proceedings are pending?
Not as usual – the registration is generally suspended from the notice date: no tax invoices, no taxable supplies, no refunds. That is why the reply should specifically ask the officer to revoke the suspension under the proviso to Rule 21A(4), and why speed matters.
My notice is for non-filing. Is there a guaranteed way out?
Yes. File all pending returns with tax, interest and late fee before or with your reply – the proviso to Rule 22(3) then obliges the officer to drop the proceedings in Form REG-20. Suspension lifts with the drop order.
The notice gives no real reason – just quotes the section. Is that valid?
Courts have consistently set aside such notices. The Delhi High Court in Fada Trading and Rishiraj Aluminium quashed cancellation SCNs that lacked material particulars or an intelligible reason – a notice you cannot meaningfully answer violates natural justice.
The officer visited my premises and reported me non-existent. What now?
Physical verification has its own rules: the REG-30 verification report with photographs must be uploaded within 15 working days, and verification behind the taxpayer’s back has been held unsustainable. Reply with your ownership/tenancy proofs, utility bills, photographs and books, and point out the verification defects.
What if the reply window has already passed?
File the reply anyway and seek condonation – and if a cancellation order has issued, move revocation under REG-21 within 90 days (after filing pending returns) or appeal under Section 107. Retrospective cancellations in particular are worth contesting.
