π Key Takeaway: Understand the 4 Golden Rules of claiming ITC under Section 16, 180-day supplier payment rule under Rule 37, and the exhaustive list of blocked credits under Section 17(5).
What is Input Tax Credit (ITC)?
Input Tax Credit (ITC) is the foundational mechanism of the GST architecture that eliminates the cascading effect of double taxation. When you purchase goods or services for your business, you pay GST to your vendor. You can subtract this tax already paid from the output GST collected from your customers, remitting only the balance difference to the government.
The 4 Mandatory Conditions to Claim ITC (Section 16(2))
A registered taxpayer can claim ITC only if all four statutory conditions are satisfied simultaneously:
- Possession of Tax Document: You must hold a valid Tax Invoice, Debit Note, or Bill of Entry issued by a registered supplier.
- Receipt of Goods or Services: The goods must have been physically received or the services completely rendered.
- Supplier Tax Payment & Filing: The vendor must have declared the invoice in their GSTR-1 and paid the taxes in GSTR-3B, ensuring it appears in your auto-generated GSTR-2B statement.
- Return Filing: You must furnish your valid return in Form GSTR-3B under Section 39.
The 180-Day Payment Rule (Second Proviso to Section 16(2))
If a buyer fails to pay the supplier the full invoice value including GST within 180 days from the invoice date, the ITC claimed earlier must be reversed in GSTR-3B along with interest at 18% per annum under Section 50. The credit can be reclaimed once payment is released.
