A customer calls: "Your GST number shows suspended. We can't claim credit on your invoice." Your stomach drops. Suspension and cancellation are serious, but most cases can be fixed if you act fast and use the right form.
Here's how to read your status, respond correctly and get back to "Active".
First step: Open the GST portal and read the actual notice: REG-31, REG-17 or REG-19. Each has a different response and deadline. Replying on the wrong form wastes precious days.
Suspended vs cancelled
| Status | What it means | What to do |
|---|---|---|
Suspended (system, REG-31) | Return mismatch or bank-account (Rule 10A) issue | Explain or fix within 30 days |
Suspended (officer, REG-17) | Cancellation proceedings started | Reply in REG-18 within the notice period |
Cancelled by officer (REG-19) | Registration cancelled under Section 29 | File REG-21 revocation, or appeal |
Cancelled on your application | You applied to cancel | Revocation generally isn't the route; consider fresh registration |
Why GSTINs get suspended
Under Rule 21A of the CGST Rules, suspension can follow:
- your own cancellation application
- an officer starting cancellation proceedings (non-filing of returns, not operating from the declared place, fake invoices)
- a system-based REG-31 for significant differences between GSTR-1 and GSTR-3B, or between GSTR-3B and inward-supply data
- not furnishing bank-account details as required by Rule 10A
While suspended, you cannot make taxable supplies, and buyers may face credit issues.
Good news: When proceedings are dropped after your reply, suspension is revoked from the date it started.
Revoking a cancellation: REG-21
If an officer cancelled your GSTIN, apply in Form GST REG-21 within 90 days of the date the cancellation order was served. Under Rule 23, the Additional or Joint Commissioner can extend this by up to 180 days on sufficient cause, so the maximum is 270 days.
Before applying, file all pending returns and pay the tax, interest and late fee up to the cancellation date. Applications without that are usually rejected.
After 270 days, REG-21 is closed. Your options are an appeal under Section 107 (within its time limits) or a fresh registration.
A worked example
Ravi Traders missed GSTR-3B for six months during an illness. An officer issues REG-17 and later cancels the registration (REG-19) on 10 August 2026.
- Ravi files all pending returns and pays the dues by 25 September.
- He applies in REG-21 on 28 September, well within 90 days.
- The officer accepts, and the GSTIN is restored.
Had Ravi waited until December, he would have needed a condonation request with reasons, and the outcome would have been uncertain.
Don't: Don't keep invoicing as normal while suspended. Supplies made during suspension create credit problems for your buyers and complications for you.
