Overview

What is a GST NIL Return Filing?

A Nil return is a GST return filed for a tax period in which a registered person has no transactions to report — no outward supplies, no inward supplies attracting reverse charge, no input tax credit to claim, and no other liability.

Guide to GST Nil Return Filing

Salient Features, Documents/Records Required, Filing Process, and FAQs

1. Introduction

A Nil return is a GST return filed for a tax period in which a registered person has no transactions to report — no outward supplies, no inward supplies attracting reverse charge, no input tax credit to claim, and no other liability.

Under the Central Goods and Services Tax Act, 2017, filing a return is mandatory for every registered person for every applicable tax period, irrespective of whether any business activity took place; a taxpayer with genuinely no transactions in a period must still file a Nil GSTR-1 and a Nil GSTR-3B (or Nil CMP-08, for a composition dealer) for that period.

Recognising that many small or dormant businesses have periods of complete inactivity, the GST Network (GSTN) allows Nil returns to be filed either through the standard online process on the GST portal or, for eligible taxpayers, through a simplified SMS-based facility under Rule 67A of the CGST Rules, 2017, without needing to log in to the portal at all.

2. Salient Features

Mandatory Even with Zero Activity Filing is compulsory for every applicable tax period regardless of turnover or business activity; 'no transactions' is not a reason to skip filing, only a reason to file as Nil.
Strict, Transaction-Based Test (Not Just 'No Sales') A return qualifies as Nil only if there is no outward supply of any kind (including nil-rated, exempt, and non-GST supplies), no inward supply attracting reverse charge, no credit or debit note issued or amended, no advance received or adjusted for services, and — for GSTR-3B — no input tax credit to claim and no interest or late fee outstanding for the current or any earlier period.
Applies Separately to GSTR-1 and GSTR-3B GSTR-1 (outward supplies) and GSTR-3B (summary liability and payment) each have their own, distinct Nil-filing conditions, and both may need to be filed as Nil independently for the same period.
Two Independent Filing Channels A Nil return can be filed through the standard online process on the GST portal (Services > Returns > Returns Dashboard), or, where eligible, through a short SMS sent from the authorised signatory's registered mobile number to the GSTN number 14409, without logging in to the portal. SMS-based Nil filing under Rule 67A requires no documents or attachments.
Auto-Population & Sequential Dependencies A Nil GSTR-3B cannot be filed unless all GST returns for earlier tax periods have already been filed. The Nil-filing option is automatically disabled if any data has been auto-populated from GSTR-1/IFF or GSTR-2B, or if the taxpayer has made any manual entry, since this indicates the period is not genuinely Nil.
Distinct from 'Zero Filing' & Irrevocable Status A true Nil return has no data to report at all, whereas 'zero filing' is a scenario where a taxpayer manually edits fields down to zero or negative values; the Nil checkbox is unavailable here. Once filed, a Nil return cannot be revised; subsequent discoveries must be handled via amendment mechanisms in a later period.

Key Timing, Fees & Verification Rules

  • Timing Restriction: A Nil return can only be filed on or after the 1st of the month following the tax period (e.g., a return for April can only be filed from 1 May onwards).
  • Late Fee Penalties: There is no separate government fee for filing a Nil return, but if it is filed after its due date, it still attracts the standard late fee (typically ₹20 per day, split equally as CGST and SGST).
  • Verification OTPs: Verification requires a one-time code — an email/mobile OTP for online filing, or a 6-digit code sent by GSTN for SMS filing (valid for 30 minutes, usable once).
  • Broad Scopes: Nil filing is available to normal taxpayers, casual taxable persons, SEZ units, SEZ developers, and composition dealers (CMP-08).

3. Documents/Records Required (to Confirm Nil Status)

Because a Nil return reports no transactions, no supporting documents are uploaded with the filing itself. However, taxpayers must verify and retain records to confirm that Nil filing is genuinely appropriate:

Records to Check Verification Criteria & Actions Required
3.1 Sales & Purchase Registers • Review to confirm absolutely zero outward supplies (including nil-rated, exempt, or non-GST supplies).
• Ensure no inward supplies liable to reverse charge have been received.
3.2 Accounting Adjustments • Confirm that no credit notes or debit notes were issued, received, or amended.
• Verify that no advance was received or adjusted for services during the tax period.
3.3 Auto-Generated Statements • Check the **GSTR-2B statement** to confirm that no input tax credit is reflected or being claimed.
• Check the GST portal ledger for any outstanding tax, interest, or late fee from an earlier period.
3.4 Portal & Credential Readiness • Ensure all GST returns for earlier tax periods have already been filed (sequential filing).
• Keep valid login credentials ready for online filing, or secure access to the registered mobile number for SMS filing.
• **Composition Dealers:** Confirm no outward supply, reverse-charge liability, or amendments before filing Nil CMP-08.

* Note: If any of these checks reveal even a single reportable transaction, amendment, or outstanding liability, the return does not qualify as Nil and must instead be filed with actual figures through the standard process.

4. Return Filing Execution Workflows

4.1 Online Portal Filing Methods (GSTR-3B & GSTR-1)

Filing Nil GSTR-3B Online
  1. Log in to the GST portal, navigate to Services > Returns > Returns Dashboard, and select the financial year and period.
  2. Answer the eligibility questionnaire: choose 'No' to all questions regarding outward supplies, inward supplies, ITC claims, interest, or late fees.
  3. Mark 'Is Nil Return' as Yes (disabled if auto-populated data exists); the system creates a draft summary with all entries at zero.
  4. Click 'Preview Draft GSTR-3B' to verify, execute OTP verification via email/mobile (or use DSC), and confirm submission. Download the final copy containing the 'Filed' watermark.
Filing Nil GSTR-1 Online

Open GSTR-1 for the relevant period from the dashboard. If no invoices, notes, amendments, or advances have been entered or saved, select the Nil filing checkbox. Preview the draft, and submit using OTP, EVC, or DSC following the same pattern as GSTR-3B.

* Open frames: Nil GSTR-1 can be filed from the 1st of the following month (monthly filers) or the 1st of the month after the quarter ends (quarterly filers).

4.2 Filing Nil Returns Through SMS Protocol

Step 1: Dispatch Initial Request Text

From your registered mobile number, send an SMS to the GSTN number 14409 in the following format:
NIL <space> Return Type <space> GSTIN <space> Tax Period (MMYYYY)
(Use Return Type: '3B' for GSTR-3B, 'R1' or '1' for GSTR-1, 'CR' for CMP-08. E.g., NIL 3B 07AAAAA0000A1Z5 052026)

Step 2: Catch Security Verification Code

If the combination satisfies the system's Nil conditions, GSTN issues a 6-digit numeric verification code to your device. This token remains valid for exactly 30 minutes and is restricted to a single use.

Step 3: Confirm Submission & Log ARN

Send a secondary confirmation SMS to the exact same number (14409) using the format:
CNF <space> Return Type <space> Verification Code (E.g., CNF 3B 123456).
On successful validation, an Application Reference Number (ARN) will arrive via SMS/email. You can track this status on the portal under Services > Returns > Track Return Status.

Filing Prerequisites for SMS Mode • **Mobile Uniqueness:** The mobile number must be registered on the portal and unique to that signatory for the GSTIN. If linked to multiple signatories, update it first via a non-core amendment.
• **No Saved Portal Data:** There must be absolutely no data saved or submitted in the online version of the return for that period.
• **Block Rules:** Entering an incorrect verification code more than three times in a day blocks the combination for 24 hours (online portal routes remain available).

5. Frequently Asked Questions (FAQs)

Collapsible FAQs (or accordions) let visitors browse questions and click to expand answers, keeping pages uncluttered

Is filing mandatory even if a business had absolutely no transactions in a period? +
Yes. Every registered taxpayer must file the applicable return for every tax period, regardless of business activity; where there is genuinely nothing to report, the return must be filed as Nil rather than skipped altogether.
Can a return be filed as Nil just because there were no sales? +
Not necessarily. A return qualifies as Nil only if there are no outward supplies, no reverse-charge inward supplies, no credit/debit notes or amendments, no advances for services, and — for GSTR-3B — no input tax credit to claim and no outstanding interest or late fee; even one such item disqualifies the period from Nil filing.
When can a Nil return be filed for a given tax period? +
A Nil return can be filed only on or after the 1st of the month following the relevant tax period — for instance, a Nil return for April can be filed from 1 May onwards, not during April itself.
What is the difference between filing Nil GSTR-1 and Nil GSTR-3B? +
GSTR-1 and GSTR-3B are separate returns with separate Nil-filing conditions; GSTR-1 concerns outward supplies and related amendments, while GSTR-3B concerns overall liability, ITC, and payment. Both must be filed, and each is evaluated as Nil independently for the same period.
How does SMS-based Nil filing work, and is it different from online filing? +
SMS filing under Rule 67A of the CGST Rules allows an authorised signatory to file a Nil GSTR-1, Nil GSTR-3B, or Nil CMP-08 by sending a short SMS to 14409 from their registered mobile number, followed by a confirmation SMS with a verification code, without needing to log in to the GST portal; the underlying eligibility conditions are the same as for online Nil filing.
Is there a fee for filing a Nil return? +
There is no separate fee to file a Nil return itself. However, if it is filed after the due date, the standard late fee for delayed filing still applies, notwithstanding that there is no tax payable.
Can a Nil GSTR-3B be filed if there is outstanding interest or late fee from an earlier period? +
No. The Nil-filing option for GSTR-3B is disabled if there is any outstanding interest, late fee, or tax liability carried forward from an earlier tax period; such dues must be cleared, or reported and paid through the standard filing process, before Nil filing becomes available for the current period.
Can a Nil return be revised if a transaction is discovered later? +
No. Once filed, a Nil return cannot be revised. If a transaction pertaining to that period is identified afterward, it must be reported through the amendment mechanism (such as GSTR-1A, for outward supply corrections) or included in a subsequent period's return, as applicable.
What happens if the SMS verification code is entered incorrectly multiple times? +
If an incorrect verification code is submitted more than three times in a day, the GSTIN and mobile number combination is blocked from SMS-based Nil filing for that return for 24 hours; the taxpayer can still complete Nil filing through the online GST portal during this period.
Do composition dealers also have a Nil filing option? +
Yes. Composition dealers with no outward supply, no reverse-charge liability, and no amendments to previously declared supplies for a quarter can file a Nil CMP-08, either online or via SMS (using the CR format) to 14409, in the same broad manner as Nil GSTR-1 and Nil GSTR-3B.
Notice: GST Nil-return eligibility conditions, SMS formats, and portal functionality are prescribed by GSTN and CBIC and may be updated periodically. Readers are advised to verify current requirements on the GST portal (www.gst.gov.in) or consult a qualified tax professional before filing.
