How to File GSTR-6 Online – Due Date, Format & Filing Process

Last Updated: July 9, 2025

With the introduction of the Goods and Services Tax (GST), businesses have to submit various GSTR forms based on their registration status, turnover, and operations. GSTR-6 is one such return and is exclusively to be used by Input Service Distributors (ISDs).

ISDs are incorporated companies that receive invoices against services that their branches or units use and are bound to allocate Input Tax Credit (ITC) to the respective unit.

Filing GSTR-6 ensures that this distribution of credit is reported accurately every month. It is one of the most vital compliance requirements that ensure transparency and also avoid credit mismatches in the GST system.

Let’s discuss this GST return in detail.

What is GSTR-6?

GSTR-6 is a monthly GST return that every Input Service Distributor (ISD) should file. It consists of information on ITC received from suppliers and its allocation to various branches or units having the same PAN.

It is necessary to file GSTR-6 even if there is no credit to distribute. In such cases, the ISD must file a Nil return. The return includes invoice-level information on inward supplies and debit/credit notes, along with the allocation of eligible and ineligible credit.

GSTR-6 Due Date:

You must file this return on or before the 13th of the following month. The July return, for example, has to be filed on August 13.

What is Required to File Form GSTR-6?

The taxpayer has to make sure that the following conditions are fulfilled before moving on with the filing of Form GSTR-6:

  • You should have a registered business as an Input Service Distributor with an active GSTIN.
  • The taxpayer must have a valid login. Companies, LLPs, and FLLPs require a valid Digital Signature Certificate (DSC).
  • Other people may use the option Electronic Verification Code (EVC).
  • For EVC-based filing, the registered mobile number should be active to get OTPs.
  • Even if the GSTIN has now been canceled, you can file it for the period when it was active.

By fulfilling these requirements, the ISD will be able to submit returns easily.
