Section 16(2)(c) ITC Blocked: What to Do When Your Supplier Doesn't File Returns

You paid GST to your supplier. You claimed Input Tax Credit (ITC) in your GSTR-3B. Everything looked fine — until a notice arrived saying your ITC is being blocked or reversed because your supplier has cancelled their GST registration or stopped filing returns.

This is one of the most common — and most stressful — GST problems facing Indian businesses right now. The provision behind it is Section 16(2)(c) of the CGST Act, 2017. Let us break it down clearly.

What Does Section 16(2)(c) Actually Say?

Section 16(2) of the CGST Act lists the conditions that must be met before a registered person can claim ITC. Condition (c) states that the tax charged on the supply has actually been paid to the government — either in cash or through ITC utilisation — by the supplier.

In plain terms: if your supplier collected GST from you but did not pay it to the government, you lose the ITC. Your purchase was real. Your payment was real. But under this condition, the law holds you responsible for your supplier's default.

How Does the Department Detect This?

The GST portal automatically compares your GSTR-2B with your GSTR-3B. GSTR-2B is a system-generated statement that reflects only what your suppliers have actually declared in their GSTR-1. If your supplier filed GSTR-1 but did not pay tax in GSTR-3B, or if their registration got cancelled, the ITC may not appear in your GSTR-2B — or the department may issue a scrutiny notice under Section 61 or ASMT-10 pointing to the mismatch.

Three Situations Where Section 16(2)(c) Gets Triggered

Situation 1 — Supplier's registration cancelled retrospectively. If the department cancels a supplier's GSTIN with a back-dated effective date, all invoices issued after that date become invalid. Your ITC on those invoices gets questioned even if you received the goods and paid the full GST amount at the time.

Situation 2 — Supplier stopped filing GSTR-3B. Your supplier filed GSTR-1 and declared the invoice, so it shows up in your GSTR-2B. But they never paid the tax in their GSTR-3B. The liability sits on them — but the department may come after your ITC.

Situation 3 — Fake invoice or non-existent supplier. The most serious case. The supplier was never operating — only created to issue invoices and pass ITC. In this case, Section 16(2)(c) is combined with Section 16(2)(b) (goods not received) and penalties under Section 122.

Is This Fair? What Do Courts Say?

This is where it gets interesting. Several High Courts — including Allahabad, Delhi, Rajasthan, Gujarat, and Telangana — have ruled that a bona fide purchaser who received goods and paid GST to the supplier cannot be denied ITC simply because the supplier defaulted on their tax payment. The recipient is not the tax collector's guarantor.

The core legal argument accepted by many courts: Section 16(2)(c) cannot be read in isolation. The recipient must have received the goods (Section 16(2)(b)), the invoice must exist, and there must be no fraud on the recipient's part. Denying ITC where all these conditions are met and the only default is the supplier's non-payment amounts to an unconstitutional levy on an innocent party.

Note: The Supreme Court has not yet conclusively settled this question at an all-India level as of June 2026. The matter is sub-judice and different High Courts have taken different positions. Consult your CA or legal counsel for case-specific advice.

What To Do If You Receive a Notice Under Section 16(2)(c)

Step 1 — Do not panic and do not pay the demand immediately. Many such notices are issued in bulk under ASMT-10 or DRC-01A. You have 30 days to reply. Use that time.

Step 2 — Gather your documents. Collect the tax invoice, proof of payment to the supplier (bank statement or account payee cheque), e-way bill if goods were transported, goods receipt note or delivery challan, and your purchase register entry.

Step 3 — Verify the supplier's filing status. Log in to the GST portal and check your supplier's GSTIN. See whether their registration was cancelled and, if so, from which effective date. Check if their GSTR-3B is filed for the period in question.

Step 4 — Draft a reply citing High Court judgments. Your reply should state: (a) the transaction was genuine, (b) goods were actually received and used in your business, (c) full payment including GST was made through banking channels, (d) you had no reason to know of the supplier's default, and (e) cite relevant HC rulings protecting bona fide recipients.

Step 5 — Request the department to first recover from the defaulting supplier. Under the GST law, the proper recourse is for the department to recover the unpaid tax from the defaulting supplier. Only if that recovery fails, and fraud or collusion by the recipient is established, should the recipient's ITC be denied.

How to Protect Yourself Going Forward

Before placing any significant purchase order, verify your supplier's GSTIN on the GST portal. Check that their registration is active and that they are filing returns regularly. A supplier who is already a non-filer for 2–3 quarters before your purchase is a warning sign.

Make all payments by account payee cheque, NEFT, or RTGS — never cash. This is the single most important paper trail you can create for your defence. The Madras High Court and others have specifically noted that cash payments weaken the bona fide purchaser argument.

Reconcile your GSTR-2B monthly. If a supplier's invoice does not appear in your GSTR-2B, take it up with them immediately. Claiming ITC that is not in GSTR-2B has been restricted under Rule 36(4) since January 2022. Do not wait for a notice.

Key Takeaways

Section 16(2)(c) is real and the department enforces it actively. But the law also protects genuine buyers. If your transaction was real, your payment was by bank, your goods were received, and you had no involvement in the supplier's default — you have a strong legal position. Do not pay a demand without first examining your facts and getting proper advice. The ITC you protect today could be worth more than the notice amount.
