Intimation of suspension of your GST registration under Rule 21A of the CGST Rules, 2017. Your GSTIN is suspended — not yet cancelled. Act promptly to restore it.

What is a REG-31 Notice?
Form REG-31 is the Intimation of Suspension issued under Rule 21A of the CGST Rules, 2017 read with Section 29(2) of the CGST Act, 2017. It is issued by the proper GST officer when there are reasons to believe your GST registration is liable to be cancelled.
Suspension is a temporary, intermediate step — your registration is placed in suspended status while the officer examines whether full cancellation is warranted. Unlike cancellation, suspension is reversible if you respond adequately and remedy the default.
| Provision | Details |
|---|---|
| Rule 21A, CGST Rules, 2017 | Suspension of registration — procedure and consequences |
| Section 29(2), CGST Act, 2017 | Cancellation by proper officer — grounds and process |
| Form REG-31 | Intimation issued to taxpayer of suspension |
| Effective date | Suspension takes effect from the date specified in REG-31 |
Grounds for Receiving REG-31
Under Rule 21A, a proper officer may suspend GST registration on any of the following grounds:
- Return filing defaults: Failure to file returns for consecutive tax periods (6 months for monthly filers, 2 consecutive quarters under QRMP)
- ITC discrepancies: Significant mismatch between ITC claimed in GSTR-3B and eligible ITC as per GSTR-2B
- Output tax liability discrepancy: Significant difference between GSTR-1 outward supplies and GSTR-3B tax paid
- Suspected fraud or misrepresentation: Officer has reason to believe registration was obtained fraudulently
- Non-compliance with e-invoicing: Applicable taxpayers not generating e-invoices
- Verification failure: Inability to verify existence of business at registered address
What Suspension Means for Your Business
From the date of suspension, all of the following are restricted or affected:
- You cannot issue tax invoices — any invoice issued during suspension is invalid for ITC purposes for the buyer
- You cannot file GSTR-1, GSTR-3B or any returns (the portal blocks filing)
- You cannot claim Input Tax Credit during the suspension period
- Your GSTIN shows as "Suspended" on the GST portal — visible to all buyers who check your GSTIN
- Buyers who receive invoices from a suspended supplier risk ITC reversal — this has downstream commercial implications
Note on Returns: Even during suspension, pending returns for periods before the suspension date can still be filed. The system restriction applies to new return periods. All dues including interest must be cleared to support a request for revocation.
How to Respond to REG-31
Unlike REG-17 (which has a specific response form REG-18), REG-31 does not mandate a prescribed response form. The response process depends on the ground cited:
Identify the Ground and Gather Evidence
Read the REG-31 carefully. Identify the specific ground cited (return defaults, ITC mismatch, address verification, etc.). Collect all supporting documents — filed returns, payment challans, business address proofs, stock statements, bank statements.
File Pending Returns and Clear Dues
If the suspension is due to return filing defaults, immediately file all pending GSTR-1 and GSTR-3B returns along with full payment of tax, interest, and any late fees. This is the single most effective step to support revocation of suspension.
Submit a Written Explanation on the GST Portal
Log in to the GST portal (gstin.gov.in) → My Profile → Notices, Orders & Proceedings. Submit your reply/clarification explaining why the ground cited is not valid or has been remedied. Attach all supporting documents. Keep the explanation factual, specific, and backed by evidence.
Follow Up — Revocation or Cancellation Proceedings
If your reply is satisfactory, the officer revokes the suspension and your registration is restored. If the officer is not satisfied, proceedings for cancellation in Form REG-17 will follow. Monitoring your GST portal for further notices is essential.
