What is GSTR-6?

The Goods and Services Tax (GST) framework in India requires every Input Service Distributor (ISD) to file their monthly GSTR-6 form as part of the mandatory process. Input Service Distributors function as central units with primary headquarters of businesses that obtain input services to distribute Input Tax Credit (ITC) to their associated units following GST rules. The introduction of new April 2025 regulations enhanced the need for precise and timely GSTR-6 submissions from Input Service Distributors.

    Who Should File GSTR-6?

    The filing of GSTR-6 is essential for businesses that follow a centralized invoicing model but operate across multiple states or branches. Even if there are no transactions in a given period, ISDs are required to file a ‘Nil’ return.

    Importance of GSTR-6

    The GSTR-6 return plays a vital role in ensuring the correct distribution of Input Tax Credit among various branches of an organization. The precise allocation of ITC protects the business from duplicate credit claims and lowers taxation while streamlining credit movement throughout organization locations. The system enhances visibility and tracks service utilization across different company locations. Companies must file GSTR-6 accurately because it helps keep their records clean and minimizes the risk of receiving compliance notices amidst increased GST audits.

    The rules regarding ISD have become stricter starting April 1, 2025. Auto-populated ITC details, cross-verification with GSTR-1 and GSTR-2B, and increased audit scrutiny have made timely and precise filing essential. Mismatches or errors can now directly impact the recipient branch’s ability to claim ITC, making internal coordination and record-keeping more critical than ever.

    Due Date for Filing GSTR-6

    The GSTR-6 due date is the 13th of the month following the tax period. For example, the return for April 2025 must be filed by May 13, 2025. Timely filing ensures that distributed ITC is available for recipient units in their respective returns (GSTR-2B).

    Pre-requisites for Filing GSTR-6

    Before you begin filing GSTR-6, make sure you have these basics in place:

    • A valid GSTIN (GST registration number) issued to the Input Service Distributor (ISD)
    • The legal name and trade name of your business as registered under GST
    • The return period – that is, the month and year you’re filing for
    • Details of Input Tax Credit (ITC) you’ve received and how you plan to distribute it
    • Any debit or credit notes issued during the period

    Key Details Required in GSTR-6

    When preparing the GSTR-6 return, you’ll be asked to enter or review:

    GSTR-6 Filing Process

    Filing GSTR-6 is an online process through the GST portal. Here’s a step-by-step guide:

    1. Log in to the GST portal using ISD credentials.
    2. Go to ‘Services > Returns > Returns Dashboard and select the financial year and month.
    3. Click on ‘Prepare Online’ under GSTR-6.
    4. Enter details of ITC received, distributed, and any debit/credit notes.
    5. Use auto-populated data where available, cross-verify with invoices, and click ‘Proceed to File’
    6. Save the form and preview the summary.
    7. Submit using Digital Signature Certificate (DSC) or Electronic Verification Code (EVC).
    8. If any late fee is applicable, pay it before final submission

    There are two modes for signing and filing GSTR-6:

    1. Digital Signature Certificate (DSC)
      • Only PAN-based Class II or III DSCs are accepted by the GST Portal
      • Used for secure and verifiable digital authentication
    2. Electronic Verification Code (EVC)
      • A one-time password (OTP) sent to the registered mobile of the authorized signatory
      • Used to verify and submit the return digitally

    Alternatively, ISDs can also use the offline utility tool provided by the GSTN for bulk upload of invoice data, which is especially helpful for large enterprises with multiple branches.

    What Happens After Filing GSTR-6?

    Once GSTR-6 is filed successfully:

    • An Application Reference Number (ARN) is generated
    • An SMS and email confirmation are sent to the registered mobile and email address
    • If there are modifications or corrections, they are reflected in the counterparty’s GSTR-1 or GSTR-5 automatically

    What is GSTR-6A?

    GSTR-6A is an auto-drafted read-only form based on supplier data in GSTR-1. ISDs can’t make changes directly to GSTR-6A. Any corrections must be made during the GSTR-6 filing process itself.

    Penalties for Late Filing

    If GSTR-6 is not filed by the due date, the business becomes liable for both late fees and interest:

    • Late Fee Calculation:
      • Late Days = Filing Date – Due Date
      • Late Fee = ₹50 per day × Late Days (₹25 CGST + ₹25 SGST)
      • Maximum = ₹5,000
    • Interest on Outstanding Tax:
      • Charged at 18% per annum
      • Applicable from the due date until the date of actual payment
    • Delays in filing can impact the ability of recipient branches to claim Input Tax Credit on time, which may disrupt cash flow and affect the overall working capital management.

    Conclusion

    With GST regulations becoming more time-sensitive, GSTR-6 compliance is non-negotiable for Input Service Distributors. Accurate and timely filing ensures the smooth distribution of ITC across multiple units, helping businesses manage their tax credit efficiently.
