How to File GSTR-6 Online in 2026: Due Date & Late Fee Rules

13 July 2026

The GSTR-6 form is a monthly return filed by every Input Service Distributor (ISD) registered under GST. If your business receives invoices for input services at a head office and distributes that ITC to branches across India, you must file your GSTR-6 by the 13th of every following month. The June 2026 GSTR-6 is due on 13 July 2026.

The GSTR-6 format has 11 sections. It captures every invoice on which ITC is received, how that credit is distributed across units, and what debit or credit notes apply. Many ISDs confuse this return with GSTR-7, which is a TDS return filed by tax deductors. GSTR-6 and GSTR-7 are completely different forms for completely different taxpayer categories.

This guide covers how to file GSTR-6 online and offline, the GSTR-6 due date calendar for 2026, late filing fees, and what happens if you miss the deadline. You can also download the GSTR-6 form PDF directly from the GST portal.

 

What is GSTR-6 and Who Must File It?

GSTR-6 is a monthly GST return filed exclusively by Input Service Distributors. An ISD receives GST invoices for services used across multiple offices and distributes the input tax credit to its branches. If your business is registered as an ISD under GST, you must file GSTR-6 every month, even if there is no ITC to distribute.

 

An Input Service Distributor is usually a head office or corporate office that receives invoices for services such as software, maintenance, or consulting. These services benefit all branches, not just one. The ISD registration lets you split the ITC and pass it to each branch using the GSTR-6 form.

Take a real example. A manufacturing company has its registered office in Mumbai and factories in Pune and Surat. The Mumbai office pays a Rs. 10 lakh annual software subscription invoice with 18% GST. That Rs. 1.8 lakh ITC cannot sit with the head office if the software serves all three locations. The ISD files GSTR-6 to distribute the ITC in proportion to each branch's turnover.

The key difference between GSTR-6 and GSTR-7: GSTR-7 is filed by persons who deduct TDS under GST. GSTR-6 is filed by ISDs who distribute ITC. They have nothing in common except being monthly returns.

GSTR-6 Due Date 2026: When Must You File?

The GSTR-6 due date is the 13th of the month following the tax period. For June 2026, the due date is 13 July 2026. There is no QRMP or quarterly filing option for GSTR-6. Every ISD must file this return every single month without exception.

 

Missing the 13th deadline means you start paying late fees immediately. The GST law gives no grace period beyond the due date. If the 13th falls on a public holiday or a Sunday, the due date typically shifts to the next working day, but you should verify this on the GST portal before assuming an extension.

GSTR-6 Format: What Are the 11 Sections?

The GSTR-6 format contains 11 tables covering ISD registration details, ITC received, credit distribution to branches, debit and credit notes, and a final summary. Most fields are auto-populated from suppliers' GSTR-1 filings. The ISD must verify, accept, reject, or modify these details before filing.

 

If you download the GSTR-6 form PDF from the GST portal, you will see each table clearly labelled. Here is what each major section covers:

 

GSTR-6 Format: Section Overview

Table No.

What It Covers

Table 1-2

GSTIN and registered name of the ISD (auto-populated)

Table 3

Input tax credit received for distribution from GSTR-6A

Table 4

Total eligible and ineligible ITC available for distribution

Table 5

Distribution of ITC through ISD invoices to branches

Table 6

ITC returned to the ISD by branches (excess or ineligible)

Table 6A

Redistributed ITC previously returned by branches

Table 7

ITC mismatches and pending invoices

Table 8

Distribution of ITC through ISD credit notes

Table 9

Amendments to earlier filed GSTR-6 (corrections)

Table 10

Amendment to credit note distribution details

Table 11

Late fee and interest (if applicable)

 

The most important table is Table 5. This is where you record how much ITC goes to which branch. You need the GSTIN of each recipient branch, the ISD document type, and the tax breakup (IGST, CGST, SGST, CESS). Every entry in Table 5 must match an ISD invoice you have issued to that branch.

 

How to File GSTR-6 Online: Step-by-Step on the GST Portal

To file GSTR-6 online, log in to the GST portal, go to Returns Dashboard, select the filing month, click Prepare Online on the GSTR-6 tile, generate the GSTR-6 summary to auto-populate data from GSTR-6A, verify and accept or reject invoices, enter ITC distribution details, preview, and submit using DSC or EVC.

 

Filing your GSTR-6 online is straightforward once you understand the flow. The portal auto-fills a lot of information from suppliers' GSTR-1, so your main job is reviewing and approving those details.

 

1. Log in to gst.gov.in using your ISD credentials.

2. Click on "Returns" in the top menu, then select "Returns Dashboard."

3. Choose the financial year and tax period (month) you want to file for.

4. On the GSTR-6 tile, click "Prepare Online."

5. Scroll down and click "Generate GSTR-6 Summary." This pulls ITC details from your GSTR-6A.

6. Go to Table 3 (ITC received). Review each supplier's invoice. You can Accept, Reject, Modify, or mark as Pending.

7. Go to Table 5 and Table 8. Enter ITC distribution details: recipient GSTIN, document type, tax amounts.

8. Click "Calculate ITC" to see total eligible vs ineligible ITC.

9. Preview the return. If correct, click "Submit."

10. File using Digital Signature Certificate (DSC) or EVC (Electronic Verification Code).

 

⚠ Important: Generate GSTR-6 Summary First

Do not skip Step 5. Without generating the GSTR-6 Summary, your supplier data will not appear in Table 3. Many filers miss this step and end up with an empty return or missing ITC entries.

Once filed, you can verify your GST filing status and check if GSTR-6 submission is reflected. For ITC claims on your return, visit our guide on GST return filing to understand how distributed ITC flows into recipient branches' GSTR-3B.

 

How to File GSTR-6 Offline Using the GST Offline Tool

To file GSTR-6 offline, download the GST Offline Tool from the GST portal, open the GSTR-6 template, enter all ITC details in the Excel-based interface, generate a JSON file, log in to the GST portal, and upload the JSON under the GSTR-6 offline section. This method works well for ISDs with large volumes of invoices.

 

The offline filing method is useful if you have dozens or hundreds of invoices to enter. Doing this manually on the online portal is slow. The GSTR-6 form PDF template within the offline tool lets you enter data in bulk, validate it, and export a JSON file for portal upload.

To get the offline tool: log in to the GST portal, go to Downloads, select Offline Tools, and download the GSTR-6 Offline Tool. The tool is updated periodically, so always download the latest version before filing.

After uploading the JSON on the portal, you still need to follow Steps 8 to 10 from the online process above to preview, submit, and file using DSC or EVC. The offline tool just helps with data entry. The final filing always happens on the portal.

 

GSTR-6 Late Filing Fees and Penalties in 2026

The GSTR-6 late filing fee is Rs. 50 per day of delay (Rs. 25 CGST + Rs. 25 SGST). There is no reduced fee for NIL returns under GSTR-6. Interest on late ITC distribution may also apply. The maximum late fee is not capped under GSTR-6 unlike some other returns.

 

Missing the GSTR-6 due date is not a minor issue. Since GSTR-6 reports ITC distributed to branches, a delayed filing means recipient branches cannot claim that ITC in their GSTR-3B until the ISD files. This cascades into a cash flow problem for your entire group of entities.

✗ Penalty Alert: No Amnesty for GSTR-6 Late Fees

Unlike GSTR-9 or GSTR-3B, GSTR-6 late fees do not have an amnesty window under most GST Council decisions. Pay late fees along with your pending return to avoid GSTIN action.

If your ISD registration is blocked or suspended due to non-compliance, you can verify your GST registration status or check the GST ARN status for any pending registration applications.

 

Does an ISD File GSTR-6 Even With No Transactions?

Yes. Every ISD registered under GST must file a GSTR-6 nil return even if no ITC was received or distributed that month. Skipping the return because there were no transactions is treated as non-filing and attracts the same Rs. 50 per day late fee. There is no exemption for ISDs with nil activity.

 

This catches a lot of businesses off guard. If your ISD received no service invoices in a particular month, or if all input services came without GST (say, from an exempt supplier), you still need to log in and file a nil GSTR-6.

Filing a nil GSTR-6 is quick. You log in, go to the Returns Dashboard, select the month, open GSTR-6, generate the summary, verify that all fields are empty, and submit. It takes less than five minutes. Missing that five-minute task costs you Rs. 50 a day.

If you need help setting up your ISD correctly or amending an existing GST registration to add ISD status, you can apply for GST registration or amend your GST registration through our portal.

 

What is GSTR-6A and How Does It Connect to GSTR-6?

GSTR-6A is a read-only, auto-generated form that populates ITC details from suppliers' GSTR-1 filings. You cannot file GSTR-6A directly. Instead, after reviewing GSTR-6A, you accept, reject, or modify entries in GSTR-6. Think of GSTR-6A as your draft ITC summary — GSTR-6 is the final filed return.

 

When a supplier files their GSTR-1, the invoice details land in your GSTR-6A. Go to your Returns Dashboard on the portal and click "Prepare Online" on the GSTR-6A tile to view it. Everything there is pre-filled.

Your job in GSTR-6 is to act on each entry in GSTR-6A. If a supplier has entered a wrong invoice amount, you click Modify and correct it. If an invoice is entirely wrong, you Reject it. If you are unsure, you mark it Pending. Only accepted or modified invoices move forward into your GSTR-6 filing.

One point many ISDs miss: if a supplier files GSTR-1 after the 11th of the month, those invoices may not appear in your GSTR-6A for that month. They will show up next month. Plan your reconciliation before the 11th to avoid scrambling.

 

Frequently Asked Questions 

Q1: What is the GSTR-6 form used for?

 The GSTR-6 form is a monthly return filed by Input Service Distributors under GST. It reports ITC received on input services and records how that ITC is distributed to branches or units of the same entity across different states. Every ISD must file it by the 13th of each following month.

Q2: Who must file GSTR-6?

 Only entities registered as Input Service Distributors under GST file GSTR-6. This includes head offices or corporate offices that receive invoices for shared input services and pass on the ITC to their branches under a single PAN. Regular taxpayers, composition dealers, and TDS deductors do not file GSTR-6.

Q3: What is the GSTR-6 due date for June 2026?

 The GSTR-6 due date for June 2026 is 13 July 2026. This is the standard rule: 13th of the month following the tax period. Filing after this date attracts a late fee of Rs. 50 per day under Section 47 of the CGST Act.

Q4: What is the GSTR-6 late filing fee in 2026?

 The GSTR-6 late filing fee is Rs. 50 per day (Rs. 25 under CGST and Rs. 25 under SGST). There is no reduced fee for nil returns. The late fee continues to accrue every day until you file the return. There is no maximum cap on GSTR-6 late fees.

Q5: How do I file GSTR-6 online?

 Log in to gst.gov.in, go to Returns Dashboard, select the month, click Prepare Online on the GSTR-6 tile, generate the GSTR-6 summary, verify supplier invoices in Table 3, enter ITC distribution in Table 5, calculate ITC, preview, submit, and sign with DSC or EVC. The entire process takes 20 to 40 minutes for a typical ISD.

Q6: How do I file GSTR-6 offline?

 Download the GSTR-6 Offline Tool from the GST portal Downloads section. Open the Excel-based GSTR-6 template, enter ITC and distribution details, validate, and generate a JSON file. Upload the JSON on the GST portal under the GSTR-6 offline upload section. Complete the final submission online with DSC or EVC.

Q7: Can I download the GSTR-6 form PDF?

 Yes. The GSTR-6 form PDF is available on the GST portal under Downloads. You can view all 11 tables and the full format of the return. For actual filing, you must use the online portal or the offline tool. The PDF is for reference and internal preparation only.

Q8: What is GSTR-6A and do I need to file it?

 GSTR-6A is an auto-generated read-only form that shows ITC details from suppliers' GSTR-1. You do not file GSTR-6A separately. It is a reference document. You review GSTR-6A and take action in GSTR-6 by accepting, rejecting, or modifying entries before filing.

Q9: Can I revise a GSTR-6 after filing?

 No. Once GSTR-6 is filed, it cannot be revised. Any corrections to ITC distribution or invoice details must be made in the following month's GSTR-6 filing using the amendment tables (Table 9 and Table 10). Plan and verify all details carefully before submitting.

Q10: What is the difference between GSTR-6 and GSTR-7?

 GSTR-6 is filed by Input Service Distributors to report ITC distribution. GSTR-7 is filed by persons who deduct TDS under GST. The due date for GSTR-7 is the 10th of the following month, while GSTR-6 is due by the 13th. They are for completely different taxpayer categories and serve entirely different compliance purposes.

Q11: What if I have no ITC to distribute in a month?

 You must still file a nil GSTR-6 for that month. No ITC distribution does not mean no filing requirement. Skipping the return because of nil activity attracts the same late fee of Rs. 50 per day. Log in, generate the summary with no entries, and submit the nil return.

Q12: Is GSTR-6 applicable to composition scheme taxpayers?

 No. Composition scheme taxpayers cannot register as Input Service Distributors. GSTR-6 applies only to regular taxpayers who have obtained a separate ISD registration under GST. Composition dealers file CMP-08 and GSTR-4 instead.

 

Conclusion

Every Input Service Distributor must file your GSTR-6 by the 13th of every month, no exceptions. The return covers ITC received, its distribution to branches, and any credit or debit note adjustments.

A missed deadline means Rs. 50 per day in late fees and, more importantly, blocked ITC for every recipient branch in your group. That is a serious cash flow hit for businesses running multiple locations.

If you are new to ISD registration or need to add ISD status to your existing GSTIN, you can apply for GST registration or amend your GST registration through our portal. For any compliance issues or GST notices related to ISD filings, check our GST notices page for next steps.

File on time, verify your GSTR-6A carefully, and keep your ISD invoices in order. That three-step habit is all it takes to stay clean on this return.
