Supplier Skips GST? Your ITC Vanishes — Here's Why

Under GST law, small business owners can lose their input tax credit — a key cost-saving benefit — if their supplier fails to pay GST to the government. This rule, called Section 16(2)(c), has caused major headaches for honest businesses who did nothing wrong.

Here's what happened: Section 16(2)(c) of the CGST Act blocks a buyer's input tax credit if the supplier fails to pay GST to the government, even when the buyer has paid the invoice in full.. Multiple High Courts have ruled that honest buyers cannot be penalised for supplier defaults if the underlying transaction is genuine and documented — but the law still places the initial burden on the buyer.. GST reform discussions are ongoing about shifting enforcement responsibility toward defaulting suppliers and their banks, rather than punishing downstream buyers who acted in good faith..

What you should do: Check your GSTR-2B every month before filing GSTR-3B — only claim ITC for invoices that appear in GSTR-2B, which confirms your supplier has filed their returns.. Before onboarding any new vendor, verify their GST registration status and return-filing track record on the GST portal (search.gst.gov.in) — a non-filer supplier is a red flag.. If you receive a notice for ITC reversal due to supplier default, gather all proof of payment (bank transfers, invoices, e-way bills) and consult a GST practitioner — courts have consistently protected genuine buyers..

If your supplier defaults, you can re-avail the reversed ITC the moment your supplier actually pays their dues to the government — track this via GSTR-2B updates each month.
