What Is Input Tax Credit and How to Claim India GST, ITC framework + conditions + reconciliation.

• ITC = GST paid on inputs (goods purchased + services received) that becomes credit against GST payable on outputs (sales).
• Legal basis: Section 16 CGST Act 2017 + CGST Rules 36-45.
• Chain: supplier charges GST → registered buyer pays → buyer claims ITC against output GST liability.
• Net GST payable = Output GST - ITC claimed.
• Prevents cascading tax (tax on tax).
• Essential for competitive pricing + specific sector cost structure.

• Possession of tax invoice / debit note: valid tax invoice (Section 31 CGST Rule 46 compliant).
• Receipt of goods / services: physical receipt of goods OR constructive receipt (bill-to-ship-to acceptable per Section 16(2)).
• Supplier has filed GSTR-1: outward supplies reported.
• Supplier has paid tax: GSTR-3B filed + tax paid to government.
• Recipient has filed GSTR-3B: ITC claim reported.
• Payment made to supplier: within 180 days of invoice date. If not: ITC reversible + specific interest.
• No Section 17(5) blocked credit: specific blocked categories (vehicles for personal use, food/beverage, specific scenarios).
• Section 16(4) time limit: ITC must be claimed by earlier of (a) specified date following FY (currently 30 November following FY), (b) date of filing annual return.

• GSTR-2B: auto-populated statement showing ITC available based on supplier's GSTR-1 + GSTR-3B.
• Generated monthly for recipient based on supplier filings.
• Rule 36(4) imposes 2A/2B rule: ITC claim restricted to invoices appearing in 2B + specific cap.
• Monthly reconciliation: recipient's books vs GSTR-2B.
• Discrepancies: (a) supplier not filed GSTR-1 → ITC not in 2B → follow up with supplier, (b) supplier not paid tax → ITC may be challenged, (c) wrong invoice details → correction / amendment.
• Monthly discipline critical for timely ITC claim + specific defence in GST audit.
