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
-
- Download GSTR-2B.
-
- Compare with purchase register.
-
- Identify missing invoices.
-
- Follow up with vendors before GSTR-3B filing.
-
- Check high-value suppliers.
-
- Track vendors who file GSTR-1 but not GSTR-3B.
-
- Maintain vendor-wise ITC ageing.
-
- Reverse ITC where required.
-
- Re-avail ITC when legally allowed.
-
- 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.
