GST REG-31 Notice: Registration Suspended, What to Do
You did not miss a deadline. You did not ignore a notice. And yet your GST registration shows as suspended, and you cannot issue tax invoices starting immediately. This is what a REG-31 intimation does, and it is one of the few GST actions that takes effect before you have had any chance to explain yourself.
Form GST REG-31 is an intimation issued under Rule 21A(2A) of the CGST Rules, triggered automatically when the system compares your GSTR-3B against your GSTR-1 or GSTR-2A/2B and finds significant differences or anomalies suggesting a contravention that could lead to cancellation, or when there is a contravention of Rule 10A relating to your bank account details. Your registration is suspended from the date of this communication, and you are given thirty days to explain why it should not be cancelled.
This article explains exactly what triggers a REG-31, what suspension actually stops you from doing immediately, how the thirty-day reply window works, and what happens once you are restored.
What Triggers a REG-31 Intimation
Rule 21A(2A) specifically covers two situations:
- A comparison of the returns you filed under Section 39, meaning your GSTR-3B, against the details of outward supplies in GSTR-1, or against the inward supply details derived from your suppliers' GSTR-1 filings reflected in your GSTR-2A or GSTR-2B, reveals significant differences or anomalies indicating a contravention of the Act that could lead to cancellation
- A contravention of Rule 10A, which requires furnishing your bank account details on the portal within the prescribed time after registration
If either condition is met, the system suspends your registration and intimates you through Form GST REG-31, electronically on the portal or through the email address registered at the time of your registration, highlighting the specific differences, anomalies, or non-compliance identified.
What Suspension Actually Means, Starting Immediately
This is the part most people miss, and it matters more than almost anything else in this notice. The suspension takes effect from the date the REG-31 communication is sent to you, not from some later date after you have had a chance to respond.
While suspended, you cannot make any taxable supply, which in practical terms means you cannot issue a tax invoice or charge tax on supplies during this period. You are also not required to furnish returns under Section 39 for the suspension period, and you will not be granted any refund under Section 54 while the suspension is in effect. This is a real, immediate operational stop, not a warning about something that might happen later.
The 30-Day Rule
Once you receive REG-31, you are required to explain, within thirty days, why your registration should not be cancelled. Your reply should directly address the specific differences, anomalies, or bank account contravention flagged in the notice, supported by a clear reconciliation and any relevant documents.
If your explanation is satisfactory, the proceedings are dropped and your registration is restored through an order in Form GST REG-20. If you do not respond within the thirty days, or your explanation is not accepted, the matter can proceed toward formal cancellation of your registration.
How to Reply
- Log in to the GST portal and locate the REG-31 intimation against your GSTIN.
- Identify precisely which discrepancy is flagged: a GSTR-3B versus GSTR-1 or GSTR-2A/2B mismatch, or a Rule 10A bank account issue.
- If the issue is a bank account contravention, the fastest resolution is usually to furnish the required bank account details on the portal immediately, since this directly closes the specific ground cited.
- If the issue is a GSTR mismatch, prepare a reconciliation showing the source of the difference, whether it is a timing issue, a supplier reporting error, or a genuine correction you have since made, similar to how you would respond to a DRC-01B or DRC-01C intimation for the underlying mismatch itself.
- Submit your explanation and supporting documents through the portal within the thirty-day window.
- Track your application status to confirm whether REG-20 has been issued restoring your registration.
Restoration Is Not Automatically the End of the Story
Once your registration is restored, two things follow that are easy to overlook. First, you are required to file your first return after restoration covering all transactions carried out during the suspension period, since you were not required to file returns while suspended but the transactions themselves still need to be accounted for. Second, for supplies made during the suspension period where you could not issue a proper tax invoice at the time, you have the option to issue revised tax invoices once restored, under Section 31(3)(a), to properly document and charge tax on those transactions retroactively.
Do not treat restoration as simply flipping back to business as usual. The transactions from the suspension window still need to be cleaned up.
REG-31 vs REG-17: Two Different Roads to Suspension
Both notices can result in a suspended registration, but they arrive through very different mechanisms and carry different timelines.
| REG-31 | REG-17 | |
|---|---|---|
| Trigger | Automated system comparison of GSTR-3B vs GSTR-1/2A/2B, or a Rule 10A bank account contravention | Officer's independent reasons to believe cancellation is warranted under Section 29 |
| Governing rule | Rule 21A(2A) | Rule 22, alongside suspension under Rule 21A(2) |
| Suspension timing | Effective from the date of the REG-31 communication itself | Often effective from a date the officer determines, alongside the notice |
| Reply window | 30 days | 7 working days, via Form REG-18 |
| Favourable outcome | Registration restored via REG-20 | Proceedings dropped via REG-20 |
If your notice references a specific GSTR mismatch percentage or a missing bank account, you are dealing with REG-31. If it cites broader grounds like non-filing history or a fraud allegation, that is REG-17, covered separately in this series.
FAQs: People Also Ask
What is a GST REG-31 notice? REG-31 is an intimation issued under Rule 21A(2A) of the CGST Rules when the system detects significant differences between GSTR-3B and GSTR-1 or GSTR-2A/2B, or a contravention of Rule 10A regarding bank account details, resulting in automatic suspension of your registration.
What is the time limit to reply to a REG-31 notice? You must explain the flagged discrepancy within thirty days from the date of the intimation.
Can I issue tax invoices while my registration is suspended under REG-31? No. During suspension, you cannot make any taxable supply, which means you cannot issue a tax invoice or charge tax on supplies during that period.
Do I need to file GST returns while my registration is suspended? No. You are not required to furnish returns under Section 39 during the period your registration is suspended.
What happens to transactions I made during the suspension period once my registration is restored? You must file your first return after restoration covering all transactions carried out during the suspension period, and you have the option to issue revised tax invoices for those supplies under Section 31(3)(a).
FAQs: Real Questions People Ask
I got a REG-31 for a GSTR-1 vs GSTR-3B mismatch, and I already responded to a related DRC-01B notice for the same period. Do I need to explain this twice? Yes, treat these as related but separate requirements. Your DRC-01B response addressed the liability mismatch itself, but REG-31 is specifically about whether that mismatch justifies suspending or cancelling your registration. Reference your DRC-01B reply and its outcome in your REG-31 explanation as supporting context, but make sure your REG-31 reply stands on its own and directly addresses why the discrepancy does not warrant cancellation of your registration.
My registration got suspended and I genuinely forgot to add my bank account details after registering. How fast can I fix this? This is usually the most straightforward version of a REG-31 issue. Log in to the portal and furnish your bank account details immediately, since this directly resolves the specific Rule 10A contravention cited. Submit your explanation referencing that you have now completed this requirement, and this tends to move toward restoration faster than a GSTR reconciliation dispute would.
I was suspended for three weeks and couldn't invoice several customers during that time. What happens to those sales now that I'm restored? Once restored, include all transactions from the suspension period in your first return filed after restoration. For the specific supplies where you could not issue a tax invoice at the time due to the suspension, you can issue revised tax invoices under Section 31(3)(a) to properly account for and charge tax on those transactions now. Keep clear records connecting each revised invoice to the original supply date and the suspension period, since this documentation will matter if the transactions are ever reviewed later.
