GST<\/a>R-6 is a monthly return filed exclusively by Input Service Distributors under the GST framework. It is a specialised return that plays a critical role in how large organisations distribute Input Tax<\/a> Credit across their various branches and units. If your business has a head office receiving services on behalf of multiple branches, understanding GSTR-6 and the ISD mechanism is essential.<\/p>\n

What is an Input Service Distributor?<\/h2>\n

An Input Service Distributor (ISD) is a business entity (usually a head office or registered office) that receives invoices for input services on behalf of its branches or business units. The ISD then distributes the Input Tax Credit arising from those services to its branches proportionately.<\/p>\n

Common examples of ISD situations include:<\/p>\n

– A company’s head office paying for software licences, legal consultancy, or corporate insurance for the benefit of all its regional branches.
\n– A holding company receiving centralised services and distributing the credit to its operating subsidiaries registered as different GSTIN<\/a>s.<\/p>\n

What is GSTR-6?<\/h2>\n

GSTR-6 is the monthly return filed by an ISD. It reports:<\/p>\n

– Inward supplies received by the ISD (input services with ITC).
\n– The distribution of ITC to recipient GSTINs (branches, units, or subsidiaries).
\n– Any amendments to previously reported distributions.<\/p>\n

Due Date for GSTR-6<\/h2>\n

GSTR-6 must be filed by the **13th of the month following** the relevant tax period. It is filed monthly regardless of turnover.<\/p>\n

How ITC Distribution Works<\/h2>\n

The ISD distributes ITC to recipient units based on the proportion of their turnover to the total turnover of all units. Different rules apply for CGST, SGST, and IGST<\/a>:<\/p>\n

– CGST credit received by an ISD can only be distributed as CGST to units in the same state.
\n– SGST credit received by an ISD in one state is distributed as IGST to units in other states.
\n– IGST credit can be distributed to any unit as IGST, CGST, or SGST as applicable.<\/p>\n

If input services are specifically attributable to one unit, 100% of the credit goes to that unit.<\/p>\n

ISD Registration<\/h2>\n

A business unit that wants to act as an ISD must take a separate GST registration as an ISD, in addition to its existing GSTIN as a regular taxpayer. This dedicated ISD registration is used only for receiving and distributing credit. The ISD does not use this registration to make taxable supplies.<\/p>\n

Ineligible ITC Under ISD<\/h2>\n

An ISD cannot distribute ITC that relates to supplies that are exempt, or ITC that is blocked under Section 17(5)<\/a> of the CGST Act (such as ITC on motor vehicles or personal consumption expenses<\/a>). Only eligible ITC from input services can be distributed.<\/p>\n

Practical Example<\/h2>\n

National Bank Ltd’s corporate office in Mumbai receives a legal advisory invoice for Rs. 10 lakhs (IGST Rs. 1.8 lakhs). The services benefit all its branches across India. The head office, registered as an ISD, distributes the Rs. 1.8 lakhs ITC to its branches proportionately based on their respective turnover shares<\/a>. Each branch receives its share in their Electronic Credit Ledger, which they can use to offset their own output GST liability.<\/p>\n

GSTR-6A: Auto-Populated Draft<\/h2>\n

GSTR-6A is an auto-populated draft of inward supply details for the ISD, generated from suppliers’ GSTR-1<\/a> filings. The ISD verifies this data before preparing and filing GSTR-6.<\/p>\n

Key Takeaways<\/h2>\n

– GSTR-6 is a monthly return filed by Input Service Distributors by the 13th of the following month.
\n– ISDs receive input service invoices on behalf of multiple branches and distribute ITC to those branches.
\n– ISD registration is separate from the regular GSTIN of the same entity.
\n– ITC distribution is proportional to each recipient unit’s turnover.
\n– Only ITC on input services can be distributed. Goods and blocked credits are excluded.
\n– CGST and SGST credits must follow state-specific distribution rules.<\/p>\n

The ISD mechanism simplifies ITC management for companies with multiple GST registrations. Proper GSTR-6 filing ensures each branch gets its correct share of credits and reduces the risk of ITC disallowance.<\/p>\n","protected":false},"excerpt":{"rendered":"
