GST returns get blocked when there are 3 or more consecutive months of non-filing, or when the officer bars filing due to sustained default.
The unbarring process step by step:
1. Taxpayer files an application with the jurisdictional GST officer (via GST portal or written request) explaining the reason for default and requesting permission to file blocked returns.
2. Officer reviews and, if satisfied, approves the unbarring on the portal.
3. Once unbarred, the taxpayer gets a 30-day window to file ALL pending returns from the blocked period.
4. If returns are not filed within 30 days, they get blocked again and a fresh application is needed.
Two critical things unbarring does NOT waive:
- Late fee: applies to each pending return from the original due date. For GSTR-3B, Rs 25 per day for CGST and Rs 25 per day for SGST (maximum Rs 10,000 per return; Rs 500 per return for nil returns).
- Interest at 18% per annum on unpaid tax liability from original due date of each month.
Calculate the total late fee and interest liability before filing so there are no surprises. Both need to be paid along with the pending returns.
If the blocked returns are linked to a cancelled or suspended registration, the path to regularize is slightly different and involves a revocation step first. This guide on [revocation of GST registration cancellation](https://taxgarden.in/blog/revocation-cancellation-gst-registration) explains that process.
