Introduction
The GST return filing framework is built on a sequential architecture. GSTR-1 reports outward supplies. GSTR-3B summarises the tax liability and payment. A taxpayer who files GSTR-1 but fails to file GSTR-3B has reported their sales to the government but has not discharged the corresponding tax liability. This triggers a cascade of compliance consequences that can disrupt business operations and expose the taxpayer to significant financial penalties.
This guide explains the legal framework, the business impact, and the remedies available when GSTR-1 is filed but GSTR-3B is not filed.
Legal Framework: Section 39 and Section 46 of the CGST Act, 2017
Sequential Filing Requirement
Section 39 of the CGST Act, 2017 provides for the filing of returns. Under the sequential filing system introduced by the GST Council, GSTR-1 must be filed before GSTR-3B for the same tax period. Once GSTR-1 is filed, the tax liability is auto-populated in GSTR-3B. However, the filing of GSTR-3B is a separate and mandatory obligation.
Notice for Non-Filing
Section 46 of the CGST Act provides that where a registered person fails to furnish a return, the proper officer may issue a notice in FORM GST REG-17 requiring the person to furnish the return within 15 days.
Assessment Under Section 62
Where the registered person fails to furnish the return even after the notice under Section 46, the proper officer may proceed to assess the tax liability to the best of their judgment under Section 62 and issue an assessment order in FORM GST ASMT-13.
Business Impact of Not Filing GSTR-3B
Interest Liability
Interest under Section 50 is payable at 18% per annum on the tax liability reported in GSTR-1 but not discharged through GSTR-3B. Interest accrues from the day after the due date until the date of payment.
Late Fee
A late fee of ₹50 per day (₹25 CGST + ₹25 SGST) is payable for the delayed filing of GSTR-3B, subject to a maximum of ₹5,000. For nil returns, the late fee is ₹20 per day.
Blocking of E-Way Bills
The GST portal may block the generation of e-way bills for non-filers. This disrupts the movement of goods and can bring business operations to a standstill.
Suspension of Registration
Continuous default in filing GSTR-3B for six months can lead to suspension of GST registration under Rule 21A of the CGST Rules.
Best Judgment Assessment
Where the return is not filed, the proper officer may issue a notice under Section 46 and proceed to assess the tax liability under Section 62. The assessment is binding on the taxpayer unless the return is filed and the assessment is withdrawn.
Prosecution
Prolonged non-filing and non-payment can be treated as wilful suppression under Section 74, attracting a penalty of 100% of the tax not paid.
Remedies for Non-Filing of GSTR-3B
File the Return Immediately
The simplest and most effective remedy is to file the pending GSTR-3B immediately. Where the tax has already been paid, the return can be filed with the correct liability.
Pay the Late Fee and Interest
Pay the late fee of ₹50 per day and interest at 18% per annum on the unpaid tax.
Respond to Notices
Where a notice has been issued under Section 46 or Section 62, respond within the stipulated time and file the return.
Apply for Revocation
Where the registration has been cancelled, apply for revocation in FORM GST REG-21 within 30 days from the date of the cancellation order.
Best Practices to Avoid Non-Filing
- File GSTR-3B immediately after GSTR-1 for the same tax period.
- Set up automated reminders for filing deadlines.
- Reconcile the auto-populated liability before filing.
- Respond to all notices from the department promptly.
- Seek professional assistance to manage compliance efficiently.
Conclusion
Filing GSTR-1 without filing GSTR-3B is a serious compliance lapse with cascading consequences, including interest, penalties, blocking of e-way bills, and potential prosecution. The remedy is straightforward: file the return, pay the dues, and respond to notices. Timely compliance is essential to avoid business disruption.
