Input Tax Credit (ITC) is the most powerful feature of the GST system — it allows businesses to reduce their output tax liability by claiming credit for GST paid on purchases. However, claiming ITC incorrectly or without proper reconciliation is one of the top reasons for GST demand notices in India.
What is GST Input Tax Credit?
When you purchase goods or services for your business, you pay GST on those inputs. This GST paid on inputs is called ITC. You can set this off against the GST you collect from your customers (output tax), paying only the net difference to the government.
Example:
- ▸GST collected on sales: ₹50,000 (output tax)
- ▸GST paid on purchases: ₹35,000 (ITC)
- ▸Net GST payable to government: ₹15,000
Conditions for Claiming ITC
ALL of the following must be satisfied:
- ▸You possess a valid tax invoice (with supplier GSTIN, IRN if applicable)
- ▸You have actually received the goods/services
- ▸The supplier has filed their GSTR-1 and the invoice appears in your GSTR-2B
- ▸You have paid the invoice within 180 days of issue date
- ▸GST returns have been filed by you (GSTR-3B)
- ▸The goods/services are used for business purposes
ITC Blocked — Section 17(5)
ITC CANNOT be claimed on:
❌ Motor vehicles (cars, buses) used for personal transport — exception: if used for taxis, driving schools, or transportation of passengers/goods
❌ Food and beverages, outdoor catering, health services (unless in same line of business)
❌ Club memberships, employee health insurance (except mandatory ESIC/PF)
❌ Works contract for construction of immovable property (not for plant/machinery)
❌ Construction of building for own use (rent, personal use)
❌ Travel benefits to employees (hotel, air, train — unless GST collected from them)
❌ Personal consumption expenses
GSTR-2B — The ITC Reconciliation Tool
GSTR-2B is the auto-generated statement (available on 14th of each month) that shows:
The Golden Rule: Only claim ITC that appears in your GSTR-2B. Claiming ITC not in GSTR-2B leads to demand notices under Rule 86B (if ITC > ₹1 lakh) and 10% interest + penalties.
- ▸All eligible ITC available based on suppliers' GSTR-1 filings
- ▸ITC that cannot be claimed (where supplier hasn't filed or filed after cutoff)
Common ITC Mistakes and Consequences
- ▸Claiming ITC on invoices not in GSTR-2B: Department receives mismatch report → demand notice for excess ITC + 18% interest
- ▸Not reversing ITC on blocked goods: On audit, department reverses ITC + 18% interest + penalty
- ▸Claiming ITC on advances before supply is received: Provisional ITC reversal required
- ▸Not reconciling at year-end: GSTR-9 vs books discrepancy triggers GSTR-9C audit
ITC Reversal — When Required
- ▸Invoice unpaid for 180 days → Reverse ITC and re-claim when paid
- ▸Goods/services used for exempt supplies → Reverse proportionate ITC
- ▸Capital goods sold within 5 years → Reverse residual ITC
- ▸Supply of goods to shareholders/employees without consideration → Full reversal
