GST Input Tax Credit — Eligibility, Blocked ITC and Reconciliation Guide

Input Tax Credit (ITC) is the most powerful mechanism in GST — allowing businesses to reduce their GST output liability by the GST paid on purchases (inputs, input services, capital goods). However, ITC is not available on all purchases — there are specific eligibility conditions, blocked ITC provisions and reconciliation requirements that businesses must comply with. Here is the complete guide.

Conditions for Availing ITC — Section 16

All four conditions must be met:

• Possession of tax invoice: Valid GST invoice from the supplier
• Receipt of goods/services: The goods/services must actually be received
• Tax charged by supplier actually paid to government: Verified through GSTR-2B (auto-populated from supplier's GSTR-1 and GSTR-3B)
• Return filed by the recipient: GSTR-3B must have been filed

Additional condition: If payment is not made to the supplier within 180 days of invoice date, ITC claimed must be reversed (with interest) — and can be re-availed once payment is made.

Blocked ITC — Section 17(5)

ITC is specifically blocked (not available) on the following:

• Motor vehicles for personal use (except vehicles used for transportation of goods, passenger transport business, driving schools, testing)
• Food and beverages (except in food/beverage business or where obligatory for employees under law)
• Outdoor catering, beauty treatment, health services (unless business of such services)
• Membership of clubs, health and fitness centres
• Travel benefits to employees (LTC/home travel)
• Works contract services for construction of immovable property
• Goods/services for personal consumption
• Goods lost/stolen/destroyed/disposed as gift or free samples

Pro-Rata ITC Reversal — Section 17(1) and (2)

If a registered person makes both taxable and exempt supplies, ITC on common inputs must be apportioned:

• ITC attributable to taxable supplies = Total ITC × (Taxable turnover / Total turnover)
• ITC attributable to exempt supplies must be reversed
• Rule 42 (for input/input services) and Rule 43 (for capital goods) provide the detailed reversal formula

GSTR-2B Reconciliation — Key Compliance Step

ITC can only be claimed up to 100% of what is reflected in GSTR-2B. From November 2021, ITC claims in excess of GSTR-2B are automatically reversed. Businesses must:

• Reconcile purchase register with GSTR-2B monthly
• Follow up with suppliers who have not filed GSTR-1 (their non-filing blocks your ITC)
• Use IMS (Invoice Management System) to manage ITC acceptance efficiently
