Input Tax Credit Under GST: Common Mistakes That Cost Foreign Companies Money
Input Tax Credit lets businesses offset GST paid on purchases against GST collected on sales, but mismatched vendor filings and documentation gaps routinely cause credit to be denied or delayed.
Input Tax Credit (ITC) is the mechanism that keeps GST from cascading, a business can claim credit for GST paid on its purchases against the GST it collects on sales, paying only the net difference. The credit is only valid, however, if the vendor has correctly reported the corresponding sale in their own GST filing, the system cross-matches invoices between buyer and seller filings.
This creates a real dependency: if a vendor is late, sloppy, or non-compliant in their own GST filing, the buyer's ITC claim can be denied or delayed, even though the buyer did everything correctly on their end. For companies with a meaningful vendor base, periodic vendor GST-compliance checks aren't just good practice, they directly protect cash flow.
The other common ITC loss is documentation, credit claims require proper tax invoices meeting specific format requirements, and claims based on incomplete or incorrectly formatted invoices are a frequent, avoidable source of denied credit during GST audits or assessments.
