Illustration of IFF: Monthly B2B invoice reporting for QRMP taxpayers.


This guide explains IFF in GST, its purpose, eligibility, benefits, due dates, and how QRMP taxpayers can use it for faster ITC and smoother compliance.

⚙️What is IFF?


This explains the QRMP IFF meaning and how it helps small taxpayers manage B2B invoices smoothly.
IFF in GST is an optional facility for QRMP taxpayers that allows small businesses (turnover up to ₹5 crore) to upload monthly B2B invoices for the first two months of every quarter. This helps buyers get their Input Tax Credit (ITC) faster, reduces last-minute rush during quarterly GSTR-1 filing, and improves overall GST compliance.

This ensures that buyers can view invoices early in their GSTR-2A/2B and claim Input Tax Credit (ITC) on time.

👉Key Points at a Glance

1. Optional GST filing – No penalty or late fee for skipping IFF.

2. Applicable only for Month 1 & Month 2 of the quarter.

3. Invoices for the last month must go directly to GSTR-1.

4. The IFF GST limit allows uploading invoices up to ₹50 lakh per month.

5. No duplication: IFF invoices auto-populate in quarterly GSTR-1 filing.

6. Only B2B invoice reporting allowed—B2C must be filed in a quarterly return.

7. The IFF due date is the 13th of the following month for Month 1 and Month 2 of each quarter.


Why use IFF?

  • Enables buyers to claim ITC faster.

  • Avoids bulk uploading during quarter-end GSTR-1 return filing.

  • Improves transparency and timely GST compliance.

Who Can Use the Invoice Furnishing Facility (IFF)?

Only taxpayers who:

  • Have turnover up to ₹5 crore, and

  • File GSTR-1 quarterly under the QRMP scheme.

IFF is optional GST compliance — businesses can use it anytime based on the requirement.


🎯 Purpose of the Invoice Furnishing Facility (IFF)

Small taxpayers under the QRMP scheme file GSTR-1 quarterly, which delays the buyer’s ITC because their invoices reflect only after the quarter ends.

To avoid this delay, the Invoice Furnishing Facility (IFF) allows them to upload B2B invoices monthly (for the first two months).
🔹This helps buyers get ITC on time without waiting for the full quarter.


 📌What Details Need to be Submitted in the Invoice Furnishing Facility (IFF)?

1. B2B Invoices:
   All invoices issued to GST-registered buyers (B2B) for the month.

2. Debit/Credit Notes:
   Any GST debit or credit notes related to those B2B invoices.

3. Amendments:
   Corrections to previously reported B2B invoices or notes.

⚠️ Note:
B2C invoices must not be added in IFF. They should be reported only in the quarterly GSTR-1.


🌟 IFF Benefits for QRMP Taxpayers

1️⃣ Faster ITC for Buyers
Buyers get invoice details earlier in GSTR-2B, helping them claim ITC on time.

2️⃣ Optional & No Late Fee
IFF is completely optional, and missing the deadline has no penalty.

3️⃣ Auto-Populates in GSTR-1
Invoices filed in IFF automatically flow into quarterly GSTR-1, avoiding duplication.

4️⃣ Less Work at Quarter-End
Monthly uploading reduces the burden and rush while filing the quarterly GSTR-1.


⚠️ Points to Remember:

  • Once filed in IFF, invoices cannot be edited or deleted in GSTR-1

  • Keep B2B and B2C invoices separate for accurate GST filing.

  • Useful for businesses with higher B2B invoice volume under the QRMP scheme.


📝 How to Submit and File IFF on the GST Portal?

If you are unsure how to file IFF under GST, follow these steps:

  1. Log in to the GST Portal and go to Returns Dashboard.

  2. Select the financial year and the month (1st or 2nd month of the quarter).

  3. Click on Invoice Furnishing Facility (IFF).

  4. Add your B2B invoices online or upload them using the offline JSON tool.

  5. Save → Generate Summary → Submit → File using EVC or DSC.

That’s it—your monthly B2B invoice data is successfully uploaded for ITC reflection in GSTR-2B.


📢Latest GST Update (7 June 2025)

From July 2025 (GSTR-3B filed in August 2025), GSTN has introduced hard-locking of auto-filled tax liability in GSTR-3B.
This means you cannot change or edit the outward supply details in GSTR-3B directly.

👉If any correction is needed, it must be done only through GSTR-1A before filing GSTR-3B.
