Introduction

Input Tax Credit, or ITC, is one of the most important benefits under GST. It allows a registered buyer to reduce tax liability by claiming GST paid on business purchases.

However, many genuine buyers face notices and ITC reversal demands because of supplier-side defaults. Even if the buyer has paid the full invoice amount including GST to the supplier, ITC may be questioned if:

     

      • the supplier does not report the invoice in GSTR-1/GSTR-1A;

      • the invoice does not appear in the buyer’s GSTR-2B;

      • the supplier does not file GSTR-3B;

      • the supplier does not pay tax to the Government.

    This has created major hardship for genuine purchasers.

    Now, there are reports that the GST Council’s Law Committee has cleared a proposal to protect buyers from losing ITC merely because suppliers fail to deposit tax. However, until the GST Council approves the proposal and official notification/circular is issued, taxpayers must continue to follow the existing law.

    What Is Input Tax Credit?

    Input Tax Credit means credit of GST paid on purchases used for business.

    For example:

    Particulars Amount
    Purchase value ₹1,00,000
    GST paid to supplier at 18% ₹18,000
    Total invoice value paid ₹1,18,000
    ITC available to buyer, if eligible ₹18,000

    The buyer uses this ₹18,000 credit to reduce GST payable on outward supplies.

    Why ITC Is Important for Businesses

    ITC prevents double taxation. Without ITC, GST becomes a cost to business.

    For example, if a trader buys goods with GST and sells goods with GST, ITC ensures that GST is paid only on the value addition.

    Without ITC With ITC
    GST paid on purchase becomes cost GST paid on purchase is available as credit
    Higher working capital burden Lower tax outflow
    Cascading effect of tax Tax only on value addition
    Business cost increases Business remains competitive

    This is why ITC is called the backbone of GST.

    Current ITC Claim Mechanism

    At present, a buyer cannot claim ITC only because the buyer has a purchase invoice.

    The buyer must ensure that ITC is eligible under GST law and appears correctly in GST records.

    The current ITC mechanism generally depends on:

       

        • valid tax invoice;

        • receipt of goods or services;

        • supplier reporting invoice;

        • invoice appearing in GSTR-2B;

        • supplier paying tax to Government;

        • buyer filing GSTR-3B;

        • payment to supplier within prescribed period;

        • ITC not being blocked under Section 17(5);

        • time limit under Section 16(4).

      Two Major Problems for Buyers

      The two biggest practical ITC problems are:

      Problem Reason
      Invoice not appearing in GSTR-2B Supplier did not file/report invoice correctly in GSTR-1/GSTR-1A/IFF
      ITC reversal due to supplier default Supplier reported invoice but did not file GSTR-3B/pay tax

      These two issues create notices, mismatches, working capital blockage and litigation.

      Example: Buyer Paid GST but ITC Is Blocked

      Suppose Ramu is a registered supplier and Shyamu is a registered buyer.

      Particulars Amount
      Goods supplied by Ramu to Shyamu ₹1,00,000
      GST at 18% ₹18,000
      Total paid by buyer to supplier ₹1,18,000
      ITC expected by buyer ₹18,000

      Shyamu has paid ₹1,18,000 to Ramu, including ₹18,000 GST. Naturally, Shyamu expects to claim ₹18,000 as ITC.

      But Shyamu may face issues if Ramu fails in GST compliance.

      Problem 1: Invoice Not Appearing in GSTR-2B

      The first problem arises when the supplier does not report the invoice properly.

      For the buyer’s ITC to appear in GSTR-2B, the supplier must report the invoice in:

         

          • GSTR-1;

          • GSTR-1A, where applicable;

          • Invoice Furnishing Facility, where applicable.

        If the supplier does not report the invoice, the buyer’s GSTR-2B may not show the credit.

        Practical Impact

        Supplier Action Buyer Impact
        Supplier reports invoice correctly ITC may appear in buyer’s GSTR-2B
        Supplier misses invoice ITC may not appear in buyer’s GSTR-2B
        Supplier reports wrong GSTIN ITC may not appear correctly
        Supplier reports wrong amount Mismatch may arise
        Supplier files late ITC may shift to later period

        This creates difficulty for the buyer because the buyer has already paid GST to the supplier.

        Problem 2: Supplier Does Not File GSTR-3B or Pay Tax

        The second problem arises even when the invoice appears in GSTR-2B.

        Section 16(2)(c) requires that tax charged on the supply should actually be paid to the Government, either in cash or through eligible ITC.

        Therefore, if the supplier reports the invoice but does not file GSTR-3B or does not pay tax, the buyer’s ITC can be questioned.

        Rule 37A deals with reversal and re-availment of ITC where the supplier does not file GSTR-3B for the relevant tax period within the prescribed timeline.

        What Rule 37A Says in Simple Words

        Rule 37A provides a mechanism for reversal of ITC where:

           

            • the buyer has availed ITC in GSTR-3B;

            • supplier has reported the invoice in GSTR-1/GSTR-1A/IFF;

            • but supplier has not filed GSTR-3B for that tax period by the specified deadline.

          In such cases, the buyer may need to reverse ITC by the prescribed date. If the supplier later files GSTR-3B, the buyer may re-avail the credit.

          Situation Current Treatment
          Supplier reports invoice in GSTR-1 ITC may appear in GSTR-2B
          Buyer claims ITC Credit availed
          Supplier fails to file GSTR-3B by deadline Rule 37A reversal risk
          Buyer reverses ITC Credit lost temporarily
          Supplier later files GSTR-3B Buyer may re-avail ITC

          Why This Is Unfair for Genuine Buyers

          The buyer may have done everything correctly:

             

              • received goods/services;

              • obtained valid tax invoice;

              • paid full amount including GST;

              • used goods/services for business;

              • matched invoice with books;

              • claimed ITC in GSTR-3B.

            Still, the buyer may suffer because the supplier did not comply.

            This creates the following problems:

            Problem Impact on Buyer
            ITC blocked Higher cash tax payment
            ITC reversed Working capital loss
            GST notice Compliance burden
            Supplier dispute Business relationship issue
            Litigation Cost and time
            Interest/penalty risk Financial exposure

            This is why businesses have been demanding relief for bona fide buyers.

            Proposed GST ITC Relief for Buyers

            Recent reports state that the GST Council’s Law Committee has cleared a proposal aimed at protecting buyers from losing ITC if suppliers fail to deposit tax with the Government.

            This proposal is expected to reduce hardship for genuine purchasers.

            However, it is important to understand:

            This is still a proposal unless approved by the GST Council and implemented through law/rules/portal changes.

            Taxpayers should not stop following existing ITC rules until official notification is issued.

            Current Rule vs Proposed Direction

            Issue Current Position Proposed Direction
            ITC depends on supplier GSTR-1 reporting Yes, practically through GSTR-2B Buyer relief may be considered
            ITC affected if supplier does not pay tax Yes, under Section 16(2)(c) and Rule 37A mechanism Buyer may be protected in genuine cases
            Buyer risk due to supplier default High Expected to reduce
            Notices for supplier default Common May reduce if proposal is implemented
            Final legal status Existing law applies Await GST Council approval/notification

            Will GSTR-2B Become Irrelevant?

            No. GSTR-2B is unlikely to become irrelevant immediately.

            GSTR-2B is a key ITC statement and is used for ITC reconciliation. Even if buyer relief is introduced, businesses should continue to reconcile ITC with GSTR-2B.

            The expected reform may reduce harsh consequences where supplier default occurs, but it may not remove the need for:

               

                • invoice matching;

                • vendor compliance checks;

                • GSTR-2B reconciliation;

                • purchase register comparison;

                • ITC eligibility review.

              What Buyers Should Do Until the New Rule Comes

              Until official changes are notified, buyers should continue following the current ITC discipline.

              Buyer ITC Checklist

              Step Action
              1 Take valid GST invoice
              2 Verify supplier GSTIN
              3 Confirm goods/services received
              4 Match purchase register with GSTR-2B
              5 Follow up missing invoices with supplier
              6 Ensure supplier files GSTR-1/GSTR-1A
              7 Track supplier GSTR-3B filing status
              8 Reverse ITC where legally required
              9 Re-avail ITC when supplier compliance is completed
              10 Keep vendor communication proof

              Vendor Compliance Is Still Important

              Even if future relief comes, businesses should not ignore supplier compliance.

              Before dealing with vendors, check:

                 

                  • GSTIN active status;

                  • return filing track record;

                  • e-invoice applicability;

                  • invoice correctness;

                  • GSTR-1 filing;

                  • tax payment discipline;

                  • vendor reputation;

                  • high-risk vendor flags;

                  • GST portal status.

                Common ITC Mismatch Reasons

                Mismatch Reason Explanation
                Supplier did not file GSTR-1 Invoice not reflected in GSTR-2B
                Wrong GSTIN entered ITC appears in someone else’s account or not at all
                Wrong invoice value Partial mismatch
                Wrong tax amount ITC mismatch
                Wrong return period ITC appears in later month
                Supplier filed GSTR-1 but not GSTR-3B Rule 37A risk
                Credit note mismatch ITC reversal issue
                Blocked credit under Section 17(5) ITC not legally eligible
                Payment not made within 180 days ITC reversal risk under separate rule

                Practical Example: Current ITC Risk

                Particulars Amount
                Purchase from supplier ₹1,00,000
                GST charged ₹18,000
                Total paid to supplier ₹1,18,000
                Supplier reports invoice in GSTR-1 Yes
                Invoice appears in GSTR-2B Yes
                Buyer claims ITC ₹18,000
                Supplier does not file GSTR-3B by deadline Yes
                Current risk Buyer may have to reverse ITC under Rule 37A
                If supplier later files GSTR-3B Buyer may re-avail ITC

                This is the exact hardship the proposed reform may try to reduce.

                How the Proposed Relief May Help

                If implemented, the relief may help genuine buyers by reducing dependence on supplier tax payment.

                Possible benefits may include:

                   

                    • fewer ITC reversals due to supplier default;

                    • lower working capital blockage;

                    • reduced GST notices;

                    • better certainty for buyers;

                    • fewer disputes between buyers and suppliers;

                    • improved ease of doing business.

                  However, the final mechanism will depend on the GST Council’s decision and legal drafting.

                  What the Government May Still Check

                  Even with relief, the Government may still check whether the transaction is genuine.

                  Buyers should be ready to prove:

                  Requirement Proof
                  Invoice Tax invoice/debit note
                  Receipt of goods/services Delivery challan, GRN, service proof
                  Payment to supplier Bank statement
                  Business use Books and records
                  GSTIN correctness GST portal verification
                  ITC eligibility Section 16 and Section 17(5) check
                  Vendor communication Emails, reminders, ledger confirmation

                  Relief for genuine buyers will not protect fake invoices or bogus ITC claims.

                  Important Difference: Genuine Buyer vs Fake ITC

                  Genuine Buyer Fake ITC Case
                  Actual goods/services received No actual supply
                  Payment made through bank Circular/bogus payment
                  Valid invoice exists Fake invoice
                  Vendor exists Non-existent vendor
                  Books support transaction No business substance
                  ITC claimed in good faith Fraudulent credit claim

                  Any future relief is expected to protect genuine buyers, not fake ITC claims.

                  Action Plan for Businesses

                  Businesses should prepare now.

                  Monthly ITC Process

                     

                      1. Download GSTR-2B.

                      1. Compare with purchase register.

                      1. Identify missing invoices.

                      1. Follow up with vendors before GSTR-3B filing.

                      1. Check high-value suppliers.

                      1. Track vendors who file GSTR-1 but not GSTR-3B.

                      1. Maintain vendor-wise ITC ageing.

                      1. Reverse ITC where required.

                      1. Re-avail ITC when legally allowed.

                      1. Keep reconciliation working papers.

                    ITC Reconciliation Table Format

                    Businesses can maintain a simple table like this:

                    Vendor GSTIN Invoice No. Invoice Date GST Amount In Books In GSTR-2B Supplier GSTR-3B Filed Action
                    09ABCDE1234F1Z5 101 10-Jun-2026 ₹18,000 Yes Yes Pending Follow up
                    27ABCDE1234F1Z8 305 15-Jun-2026 ₹8,500 Yes No Not checked Ask supplier to amend/file
                    07ABCDE1234F1Z2 512 20-Jun-2026 ₹12,000 Yes Yes Filed Claim ITC

                    This type of reconciliation protects the taxpayer during notice or audit.

                    What to Do If ITC Notice Is Received

                    If a notice is received due to supplier default, do not respond casually.

                    Collect:

                       

                        • purchase invoices;

                        • e-way bill/e-invoice records;

                        • proof of receipt of goods/services;

                        • payment proof;

                        • GSTR-2B copy;

                        • purchase register;

                        • vendor ledger;

                        • vendor confirmation;

                        • communication with supplier;

                        • proof of supplier’s return filing, if available.

                      Then prepare a proper reply explaining that the buyer is genuine and has complied with its obligations.

                      Impact on Small Businesses

                      Small businesses suffer heavily when ITC is denied due to supplier default.

                      The impact includes:

                         

                          • extra cash GST payment;

                          • blocked working capital;

                          • difficulty recovering tax from vendor;

                          • compliance cost;

                          • notice handling cost;

                          • business uncertainty.

                        Therefore, a buyer-protection mechanism can be very helpful for MSMEs and small traders.

                        Impact on Large Businesses

                        Large businesses may also benefit because they deal with hundreds or thousands of vendors.

                        A new relief mechanism may reduce:

                           

                            • vendor follow-up burden;

                            • ITC reversal working;

                            • GST audit disputes;

                            • litigation exposure;

                            • ERP reconciliation complexity.

                          However, large businesses should still maintain robust vendor compliance controls.

                          Should Buyers Stop Checking GSTR-2B?

                          No.

                          Even if the proposal is implemented, buyers should continue checking GSTR-2B.

                          GSTR-2B remains important for:

                             

                              • monthly ITC control;

                              • purchase reconciliation;

                              • vendor compliance monitoring;

                              • audit trail;

                              • GST return filing;

                              • notice defence;

                              • annual reconciliation.

                            A relaxed rule does not mean careless ITC claiming.

                            TaxClear View

                            The proposed buyer-protection mechanism is a welcome step if implemented properly.

                            A genuine buyer should not be punished merely because the supplier failed to deposit tax after collecting GST. However, the system must also prevent fake ITC claims.

                            The ideal reform should balance both objectives:

                            Objective Need
                            Protect genuine buyers Avoid unfair ITC denial
                            Stop fake ITC Maintain invoice and transaction checks
                            Reduce litigation Clear rules and portal mechanism
                            Improve compliance Better vendor-level accountability
                            Help MSMEs Reduce working capital blockage

                            Until the law changes officially, businesses should continue reconciling GSTR-2B, monitoring vendors and complying with current ITC rules.

                            Key Takeaways

                               

                                • ITC is currently linked to supplier reporting and tax payment conditions.

                                • Buyer’s ITC may be affected if supplier does not report invoice in GSTR-1/GSTR-1A/IFF.

                                • Buyer’s ITC may also be affected if supplier does not file GSTR-3B/pay tax.

                                • Rule 37A requires ITC reversal in specified supplier non-filing situations.

                                • Reports say GST Council’s Law Committee has cleared a proposal to protect buyers from supplier default.

                                • The proposal is not final until GST Council approval and official notification.

                                • GSTR-2B reconciliation remains important.

                                • Genuine buyers should maintain invoice, payment and receipt proof.

                                • Fake ITC claims will not be protected.

                                • Businesses should strengthen vendor compliance and ITC reconciliation.

                              Conclusion

                              The current GST ITC framework places a heavy compliance burden on buyers. Even when buyers pay GST to suppliers, their credit can be affected if suppliers fail to report invoices or pay tax.

                              The proposed GST reform may bring major relief by protecting genuine buyers from supplier defaults. If implemented correctly, it can reduce litigation, working capital blockage and unfair ITC reversals.

                              However, businesses should not relax compliance until official rules are notified. Continue matching GSTR-2B, checking vendor filing, maintaining purchase records and responding properly to GST notices.
