What is a REG-17 Notice?
Form REG-17 is the Show Cause Notice issued before cancellation of GST registration under Section 29(2) of the CGST Act, 2017.
This is the most time-critical GST notice — you have only 7 working days to respond. If you fail to reply, your GST registration may be cancelled, which immediately impacts your ability to issue invoices, collect GST, and claim Input Tax Credit.
Grounds for Receiving REG-17
A REG-17 may be issued on any of the following grounds under Section 29(2) of the CGST Act:
- Non-filing of returns for 6 consecutive tax periods (for composition taxpayers) or 3 consecutive tax periods (for regular taxpayers under QRMP scheme) or 6 months (for monthly filers)
- Non-commencement of business within 6 months of obtaining registration
- Registration obtained through fraud or misrepresentation
- Business discontinued or transferred
- Turnover fallen below registration threshold (voluntary cancellation by officer is less common)
Consequences of Non-Response or Cancellation
Ignoring a REG-17 or having your registration cancelled carries serious business and compliance consequences:
- You cannot issue GST invoices after cancellation — no legal right to collect GST
- No Input Tax Credit available after effective date of cancellation
- All pending returns must still be filed up to the cancellation date
- Revocation of cancellation is possible but involves a more scrutinized process with additional compliance requirements
