The IMS (Invoice Management System) is a specialized feature in the GST portal (www.gst.gov.in) that enables registered taxpayers to review, verify, and manage invoices uploaded by suppliers. It forms the base for reconciling GSTR-2B (Input Tax Credit statement) and GSTR-3B returns.
From October 2025, the system became more interactive, requiring mandatory taxpayer actions.

Activities You Can Do on the IMS Portal

1. View All Invoices and Notes

• View all B2B invoices, debit notes, and credit notes raised by suppliers.
• Filter records by month, counterparty, or status (Accepted, Rejected, Pending).
• Check the tax breakup, GSTIN of supplier, invoice number, and uploaded date.

2. Accept Invoices

• Mark invoices as “Accepted” when they correctly match your purchase records.
• Once accepted, they are automatically considered for Input Tax Credit (ITC) in GSTR-2B.
• These invoices also appear in GSTR-3B Table 4A for ITC utilization.

3. Reject Invoices

• Reject invoices that do not correlate with your records — for example, wrong GSTIN or inflated values.
• A rejected record notifies the supplier automatically, prompting correction via GSTR-1A amendment.
• These invoices are excluded from ITC computation.

4. Mark Invoices or Notes as Pending

• Newly introduced feature (October 2025).
• Allows you to temporarily hold action on certain records:
  • Credit notes under verification.
  • Amended invoices.
  • E-commerce operator documents with discrepancies.
• Valid for 1 month (monthly filers) or 1 quarter (quarterly filers).

5. Partial ITC Reversal (for Credit Notes)

• A new field lets you specify how much ITC to reverse on each credit note.
• Example: If ₹18,000 ITC was available but only ₹9,000 used, you can reverse ₹9,000 only.
• Promotes more accurate accounting and elimination of double reversal errors.

6. Add Remarks or Notes

• While accepting, rejecting, or pending any record, you can add remarks.
• Remarks are visible to both buyer and supplier, helping in dispute resolution and transparency.

7. Generate or Regenerate GSTR-2B

• After taking actions, you can regenerate GSTR-2B to reflect updated data.
• GSTR-2B is still auto-generated on the 14th of each month, but manual regeneration allows updates if IMS actions occur later.

8. Track and Download Reports

• Download your invoice list in Excel or JSON format.
• View action summary (Accepted/Rejected/Pending totals) for audit documentation.

Advantages (Pros) of Using IMS

Disadvantages (Cons) and Limitations

Best Practices for Efficient IMS Usage

1. Review the IMS dashboard weekly instead of waiting till month-end.
2. Always use the Remark field to communicate invoice discrepancies to suppliers.
3. Regenerate GSTR-2B after taking all actions before filing GSTR-3B.
4. Maintain a parallel Excel log for high-value invoices for double verification.
5. Cross-check pending records before the auto-expiry period.

In essence, the IMS system (effective October 2025) offers Indian businesses a structured, transparent way to manage invoices and credit notes, fostering accurate Input Tax Credit reconciliation. However, taxpayers must adapt to its manual action framework to fully leverage its compliance benefits.

The Indian GST Network (GSTN) has rolled out a major enhancement to the Invoice Management System (IMS) from the October 2025 tax period. These changes aim to bring better accuracy, transparency, and control in the handling of purchase invoices, credit notes, and GSTR returns. Businesses are now required to take more active roles in reconciling invoices before filing GSTR-3B.

What Is IMS on the GST Portal?

The Invoice Management System (IMS) is an online interface on the GST portal (www.gst.gov.in) that allows taxpayers to review and take action on invoices uploaded by suppliers. It bridges the connection between GSTR-1 (outward supply) and GSTR-2B (input credit statements), ensuring real-time accuracy for Input Tax Credit (ITC) claims.

Originally introduced in late 2024, the IMS received a major upgrade in October 2025, focusing on flexibility and enhanced control for taxpayers.

Key Changes Introduced from October 2025

1. Mandatory Action Required on Every Invoice and Credit Note

Taxpayers must manually review each invoice or credit note on the IMS dashboard and mark it as:

• Accepted
• Rejected
• Pending

Auto-acceptance (deemed acceptance) is no longer applied.
This means that GSTR-2B will only include accepted invoices, ensuring that only verified documents contribute to available ITC.

2. New “Pending” Option Added

A “Pending” status has been added for selected transaction types.
Taxpayers can now delay taking a decision on specific items, such as:

• Credit notes
• Upward or downward amendments in invoices
• Rejected or modified credit note entries

The Pending status is time-bound:

• 1 month for monthly return filers
• 1 quarter for quarterly filers

After this period, action is mandatory before final GSTR-2B generation.

3. Partial Input Tax Credit (ITC) Reversal for Credit Notes

Previously, when suppliers issued a credit note, the system required a full ITC reversal, creating complications for partial ITC claims.
From October 2025, taxpayers can now:

• Revoke credit partially, only up to the extent of ITC actually availed.
• Mention exact reversal amount in the IMS interface.

Example:
If a supplier issues a ₹18,000 GST credit note but the buyer had availed ₹9,000 ITC, now only ₹9,000 can be reversed. This fixes earlier mismatches and simplifies book adjustments.

4. Option to Add Remarks

While accepting, rejecting, or pending an invoice or credit note, taxpayers can now add remarks.
These remarks are visible to both parties, allowing the supplier to understand the reason behind rejection or delay.
This feature facilitates smoother reconciliation and transparent communication across B2B transactions.

5. GSTR-2B Generation and Regeneration

Although earlier advisories had hinted that GSTR-2B would need to be manually generated, the latest GSTN clarification (October 9, 2025) confirms:

• Auto-generation of GSTR-2B will continue on the 14th of every month.
• Taxpayers can regenerate GSTR-2B manually after taking IMS actions, if any updates are made post-14th.

Hence, the system allows taxpayers to synchronize last-minute IMS changes into a regenerated GSTR-2B before filing GSTR-3B.

6. Link Between IMS and GSTR-3B Filing

From October 2025:

• GSTR-3B becomes strictly linked to IMS actions.
• Accepted invoices appear in Table 4 (ITC eligibility).
• Pending or rejected invoices do not appear unless acted upon.

If invoice details mismatch, taxpayers must correct them through GSTR-1A (supplier-side amendment), as GSTR-3B fields are now auto-populated and non-editable.

Business Impact of These Updates

Practical Example

Suppose your supplier issued an invoice of ₹1,00,000 + ₹18,000 GST, and later a ₹9,000 GST credit note.
Earlier, you needed to reverse ₹18,000 in ITC entirely if not yet reconciled.
Under the October 2025 system:

• You log in to IMS.
• Accept the first invoice, mark the credit note Pending.
• When reconciliation completes, reverse ₹9,000 ITC only — exactly matching what was availed.
  This ensures accurate accounting with flexibility.

Compliance Tips for Taxpayers

1. Check your IMS dashboard early in the tax period.
2. Take action before GSTR-2B auto-generation on the 14th.
3. Use the Remarks field to communicate properly with suppliers.
4. Download regenerated GSTR-2B if you modify data post 14th.
5. Coordinate credit note acknowledgment with vendors to avoid ITC lock-ins.

Conclusion

The October 2025 IMS reforms represent the next phase of India’s digital tax evolution. While the process demands more taxpayer involvement, it greatly enhances ITC accuracy, supplier transparency, and reconciliation efficiency.
By actively managing IMS entries, businesses can ensure seamless GST compliance and avoid ITC disputes or filing delays.

The 56th GST Council meeting, held on 3rd September 2025, ushered in one of the biggest transformations to India’s Goods and Services Tax system—officially known as GST 2.0. These changes took effect from 22nd September 2025, simplifying the complex multi-slab system into a structure that promotes fairness, transparency, and ease of compliance.

Overview of the 2025 GST Rate Reform

Previously, India’s GST system had four main slabs—5%, 12%, 18%, and 28%. As part of GST 2.0, these have been rationalized into:

• 5% (Merit Rate): Essential and mass-consumption goods
• 18% (Standard Rate): General goods and services
• 40% (Luxury/Sin Rate): Luxury goods, tobacco, betting, and other demerit sectors

Additionally, nil-rated categories now include essentials in healthcare and education, aligning with social welfare goals.

Key Revisions and Highlights

1. Food and Household Essentials

Essential goods such as shampoo, toothbrushes, detergents, soaps, and toothpaste now attract 5% GST (from 18%), significantly reducing daily household expenses. Dairy products like butter, ghee, and paneer also fall under nil or 5% rates, enhancing affordability.

2. Agriculture and Farming Inputs

To aid farmers, the GST on tractors, irrigation systems, fertilizers, and biopesticides has been reduced from 12–18% to 5%. This move corrects the inverted duty structure and encourages sustainable farming practices.

3. Healthcare Sector

The government has exempted health and life insurance from GST, while 33 life-saving drugs and medical devices now attract nil or 5% rates. This includes products like medical oxygen, thermometers, and diagnostic kits, directly benefiting hospitals and patients.

4. Education Sector

Items like pencils, erasers, notebooks, maps, and atlases have been moved to the nil-GST list. Educational aids such as geometry boxes and art materials now attract only 5% GST to support students and institutions.

5. Automobile and Electronics

GST on two-wheelers, three-wheelers, and small cars (≤350cc or ≤4000mm in length) was reduced from 28% to 18%. Likewise, televisions, ACs, refrigerators, and washing machines shifted from 28% to 18%, easing costs for common households.

6. Services Sector

Hotel accommodation below Rs. 7,500 per day and wellness or beauty services (yoga, salons, gyms) now attract 5% GST (down from 12–18%). These changes aim to boost tourism and service sectors during the festive period.

7. Rate Hikes on Luxury and Sin Goods

• Luxury cars, yachts, and motorcycles (over 350cc): 40%
• Pan masala, tobacco, and aerated drinks: 40%
• Online games, casinos, and betting activities: 40%

This step merges the compensation cess directly into the new GST rate—removing the need for double taxation layers.

Compliance and Procedural Changes

Besides rate adjustments, numerous notifications (09/2025–17/2025) were issued:

• Simplified ITC (Input Tax Credit) recovery process
• Pre-filled and auto-synced GST returns
• Faster refund timelines under Rule 91(2)
• Reduced paperwork for small and composition taxpayers

Businesses must now ensure suppliers pay their GST before claiming ITC. The GST Appellate Tribunal, launching in December 2025, will streamline dispute resolution.

Economic Impact

Experts forecast that the GST 2.0 structure will:

• Boost consumer demand by lowering retail prices
• Increase tax compliance rates through simplified returns
• Enhance small business operations under reduced rates
• Expand the tax base, compensating for minor revenue loss from exemptions

Large-scale benefits are expected across MSME, e-commerce, manufacturing, and service sectors by early 2026.

Summary

The 2025 GST reform marks India’s transition to a more efficient, transparent, and consumer-friendly tax framework. By reducing rates on essentials and increasing rates on luxury and sin goods, the government aims to drive equitable growth across all sectors. Businesses are encouraged to update their pricing, tax invoices, and accounting systems immediately to remain compliant under GST 2.0.

The Goods and Services Tax (GST) system in India is continuously evolving to increase transparency and improve compliance. One of the significant updates planned from May 2025 is the separate reporting of B2B (Business-to-Business) and B2C (Business-to-Consumer) supplies in Table 12 of the GSTR-1 return.

This blog provides a thorough explanation of this update, its impact on taxpayers, how to prepare for it, and the latest official information on the matter.

What is GSTR-1 and What Does Table 12 Currently Capture?

• GSTR-1 is a monthly or quarterly return that registered taxpayers file to report their outward supplies.
• The return is divided into multiple tables based on the type of supply.
• Table 12 of GSTR-1 currently captures the summary of B2C supplies made to unregistered persons (consumers), mainly in the form of consolidated value by state and tax rate.

At present, B2B supplies (supplies to registered persons) are reported invoice-wise in Table 4 of GSTR-1.

What is the Upcoming Change Effective May 2025?

From May 2025 onwards, taxpayers will have to separately report B2B and B2C supplies in Table 12 of GSTR-1, even though this table previously focused primarily on B2C supplies.

Key Points of the Change:

• Table 12 will now include distinct summary-level reporting of both B2B and B2C supplies.
• This change adds granularity to data collection, helping authorities perform better reconciliation.
• It is a step towards harmonizing outward supply data reported in GSTR-1 with inward supplies declared by recipients in GSTR-2B/2A.

Why Has This Change Been Introduced?

• Improve Data Accuracy: Better segregation helps track supplies accurately.
• Simplify Reconciliation: It reduces mismatches between outward and inward supplies reported.
• Ease Audit and Compliance: Authorities can analyze supply patterns more efficiently.
• Streamline Reporting Processes: Businesses can better organize their data submission.

Implications for Taxpayers

1. Enhanced Reporting Requirements

• Taxpayers need to segregate and report B2B and B2C supplies separately in Table 12.
• This requires detailed data collection and validation.

2. System & Software Upgrades

• ERP, billing, and accounting software will need updates to generate reports compliant with the new format.
• Taxpayers using third-party GST filing software should confirm readiness for this change.

3. Operational Adjustments

• Finance and compliance teams must adjust internal processes to segregate customers based on GST registration status.
• Data accuracy becomes even more critical.

4. Training & Awareness

• Staff responsible for GST filing should be trained on the revised return structure and reporting rules.

How Should Taxpayers Prepare?

Step 1: Customer Classification

• Maintain an updated database of customers with their GSTIN status (registered/unregistered).
• Review and verify GSTINs regularly.

Step 2: Update Accounting and Billing Software

• Coordinate with software vendors to ensure your system supports the new Table 12 reporting format.
• Test report generation before May 2025.

Step 3: Data Reconciliation

• Regularly reconcile sales invoices with customer classifications.
• Cross-verify supplies to ensure correct segregation of B2B and B2C.

Step 4: Internal Controls

• Implement checks to avoid misclassification.
• Ensure documentation is maintained to support reported figures.

Step 5: Monitor Official Notifications

• Keep track of updates from the GST Council and CBIC to stay informed about any changes or clarifications.
