GST Input Credit: Protecting Your Working Capital

5 min read · finshark knowledge centre

input tax credit (itc) lets you offset the gst you pay on purchases against the gst you collect on sales. done right, it keeps cash in your business. done wrong, it locks up working capital and invites notices. the rules under section 16 of the cgst act are specific — and worth understanding.

The Four Conditions for Claiming ITC

• you hold a valid tax invoice or debit note from a registered supplier;
• you have actually received the goods or services (for goods in instalments, only after the final lot);
• the supplier has paid the tax to the government — verified through your gstr-2b;
• you have filed your gstr-3b return.

The Rules That Catch Businesses Out

• the 180-day rule — if you do not pay your supplier within 180 days of the invoice date, the itc you claimed is reversed with interest;
• gstr-2b matching — you can only claim credit that actually appears in your gstr-2b, so a supplier's non-compliance becomes your problem;
• the time limit — itc for a financial year must generally be claimed by 30 november of the following year, or the date of the annual return, whichever is earlier.

Why It Is a Working-capital Issue

every rupee of eligible itc you fail to claim — or have reversed — is a rupee of extra cost. mismatches, blocked credits and missed deadlines tie up cash that could fund operations. for a business on tight margins, disciplined itc management is one of the cleanest ways to protect liquidity.

Staying on Top of It

reconcile your purchase register against gstr-2b every month, follow up with non-compliant suppliers, and track the 180-day payment window. the discipline is routine; the cash it protects is not.
