GSTR-3B Filing FAQ

What buyers ask.

How is the 2B sign-off gate enforced?

When configured, the 3B cannot be filed until the GSTR-2B reconciliation is signed off for the period. CA reviewer access enforces the gate; overrides are captured with reason.

Late fee and interest. Auto-computed?

Yes. Section 50 interest on late payment of tax and late-fee per day are drafted automatically based on filing date vs due date. The CFO sees the total payable before authorising filing.

QRMP scheme. Supported?

Yes. Quarterly Return Monthly Payment scheme is supported. Monthly tax payment via PMT-06 challans drafted automatically; quarterly 3B filing follows the same draft-review-file flow.

What if we need to revise after filing?

GSTR-3B cannot be revised under GST law. Adjustments flow through subsequent periods. The system surfaces any drafted adjustments needed and posts them to the next 3B.
