What is GSTR-6?

GSTR-6 is a monthly GST return filed by an Input Service Distributor (ISD). An ISD is an office of a business that receives invoices for services used by its branches and then passes the Input Tax Credit (ITC) on those invoices to the branches.

The return shows:

• The ITC received by the ISD
• The ITC distributed to each branch
• Any ITC that could not be distributed

Who Must File GSTR-6?

Any person registered as an Input Service Distributor under GST must file GSTR-6. A regular GSTIN cannot be used for this.

An ISD registration is a separate registration. It has its own GSTIN, even if the business already has a normal GST number on the same PAN.

From 1 April 2025, ISD registration became compulsory for offices that want to pass on ITC of input services to their branches. Businesses should check the latest rules on the GST portal or with a professional.

What Details Go Into GSTR-6?

Documents Needed Before Filing

Keep these ready:

1. ISD GSTIN and portal login details
2. Purchase invoices for input services
3. Credit and debit notes
4. Auto-drafted details in GSTR-6A and GSTR-2B
5. GSTINs of all recipient branches
6. Turnover details of each branch, which are needed to work out the share of credit
7. Details of the ISD invoice or ISD credit note issued
8. Digital Signature Certificate (DSC) or Aadhaar OTP access (EVC), depending on the type of taxpayer

Common Mistakes to Avoid in GSTR-6

• Using a normal GSTIN instead of the ISD GSTIN
• Distributing credit in a different month than the month it became available
• Giving credit to a branch that is not linked to the same PAN
• Not matching the return with GSTR-2B
• Skipping nil returns
• Entering wrong GSTINs of recipient branches
• Passing on ITC that is not allowed under Section 17(5) of the CGST Act
• Forgetting to issue ISD invoices to branches
• Not correcting errors of earlier months through amendments

Why Take Professional Help for GSTR-6 Filing?

GSTR-6 is a small return, but the distribution method is technical. A single wrong entry can lead to credit mismatch, notices and interest. A professional can:

• Check whether your office needs an ISD registration
• Prepare the pro-rata working for each branch
• Match your records with GSTR-2B
• File the return on time and keep proof of filing
• Reply to notices if they come
