How to File GSTR-3B NIL Return?

A GSTR-3B nil return must be filed even when a business has zero sales, zero purchases, and zero tax liability for the month — skipping it isn’t optional just because there was nothing to report. Miss the deadline and the penalty applies regardless of the fact that no tax was owed. This guide covers the exact due dates, the late fee math, the step-by-step filing procedure on the GST portal, and the SMS shortcut most taxpayers don’t know exists.

Steps to File NIL GSTR-3B on GST Portal

The following are the steps to file NIL GSTR-3B via GST Portal:

Step 1: Log In to the GST Portal Go to www.gst.gov.in and log in with your GSTIN, username, and password.

Step 2: Navigate to the Returns Dashboard Go to Services > Returns > Returns Dashboard. Select the financial year and the return period (month) you’re filing for.

Step 3: Select GSTR-3B Click the GSTR-3B tile, then Prepare Online.

Step 4: Confirm All Tables Are Zero Every section should already show zero — don’t manually enter anything:

• Section 3.1 (outward and reverse charge supplies) — zero
• Section 3.2 (inter-state supplies) — zero
• Section 4 (ITC eligibility) — zero
• Section 5 (exempt and nil-rated supplies) — zero
• Section 6 (tax payment) — zero liability

Step 5: Save the Form Click Save GSTR 3B and confirm.

Step 6: File the Return Click Submit, then File GSTR 3B. Verify using either:

• EVC (OTP to your registered mobile), or
• DSC (Digital Signature Certificate — required for companies and LLPs)

Step 7: Save the Acknowledgment Filing generates an ARN (Application Reference Number). Download and keep this — it’s your proof of compliance if the department ever questions a filing gap.

How to File GSTR-3B Nil Return via SMS

For businesses that genuinely had zero activity, GSTN built a filing path that skips the portal entirely:

SMS NIL 3B [GSTIN] [Tax Period in MMYYYY] to 14409 Example: NIL 3B 24AAAAA0000A1Z5 012025 for January 2025

• You’ll get an OTP by SMS
• Reply CNF 3B [OTP] to confirm
• An ARN comes back by SMS — that’s your filing confirmation

No login, no internet connection required — this works from any phone that can send a text. It’s the fastest legitimate way to clear a nil month, and it’s worth setting a monthly reminder for if a business has recurring inactive periods. The same nil-filing logic applies to GSTR-1 nil returns if you also need to clear that filing for the period.

What is the Due Date for Filing GSTR 3B?

The due date is the 20th of the following month for regular taxpayers with annual turnover above ₹5 crore. Businesses under the GST registration turnover limit of ₹5 crore get a few extra days, split by state category:

Check the full GST state code list to confirm which category your state falls under, or see the GST filing due dates calendar for all return deadlines at a glance.

Example: a nil return for January is due 20th February for a turnover-above-₹5-crore business, or 22nd/24th February for smaller businesses depending on state.

What is the Late Fees for GSTR-3B NIL Return

• ₹20 per day (₹10 CGST + ₹10 SGST) for every day past the due date
• Capped at a maximum of ₹500 (₹250 CGST + ₹250 SGST) per return period
