Ineligible Input Tax Credit (ITC) and Reverse Charge Mechanism (RCM) – Practical Understanding & Compliance

Session Objective

To help participants clearly understand:

• Which expenses block ITC under GST,
• When and how RCM applies, and
• How to avoid inadvertent ineligible‑ITC claims and RCM‑related disputes.

A. Introduction to ITC and RCM

• Brief refresher on Input Tax Credit under Section 16 of CGST Act.
• Concept of Reverse Charge Mechanism under Sections 9(3)/5(3) CGST/IGST.
• Why ITC and RCM matter for working‑capital, cash‑flow, and audits.

B. Cases of Ineligible / Blocked ITC

(Under Section 17(5) + related rules)**

Explain common categories where ITC is disallowed, with practical examples:

• Motor vehicles (small passenger vehicles, aircraft, vessels)
• Goods / services used for personal use, exempt supplies, or non‑business purposes
• Food & beverages, club / health‑club memberships, life / health insurance (where not obligatory)
• Construction of immovable property (except plant & machinery)
• Goods lost / stolen / destroyed without valid reason
• Interest, penalty, late‑fee, fines, taxes paid under compounding / penalty proceedings

Emphasis:

• How to identify blocked‑ITC at invoice level.
• Impact on GSTR‑3B, GSTR‑9/9C, and ITC reversals.

C. Reverse Charge Mechanism (RCM) - Applicability

Define RCM and then cover:

• When RCM applies:
• Notified goods and services (e.g., GTA, advocate, insurance agent, etc.)
• Unregistered suppliers to registered persons (B2B)
• Imports of services
• Calculation of liability under RCM (value + GST + cess, if any).
• Time of liability and due dates for payment (current month vs delay).

Mention:

• Conditions for availment of ITC on RCM‑paid tax (usage for business, valid invoice, etc.).

D. ITC and RCM - Practical Pitfalls

Discuss common errors seen in practice:

• Wrong assumption that all RCM‑paid GST is automatically eligible as ITC.
• Claiming ITC on expenses that fall under Section 17(5) blocks.
• Non‑reconciliation of GSTR‑2B / GSTR‑3B with books leading to ineligible‑ITC discovery at audit stage.
• Delayed RCM payment and interest consequences.

Illustrate each with a short example (e.g., GTA services, car hire, office‑party food, etc.).

E. Record‑Keeping & Compliance Tips

• Proper invoicing and documentation for RCM transactions (self‑invoice, copy of supplier invoice, etc.).
• Maintenance of separate registers for blocked‑ITC and RCM‑payable supplies.
• How to show RCM liability and ineligible‑ITC in GSTR‑3B, GSTR‑9, and GSTR‑9C.
• Quick checklist for in‑house finance teams / tax consultants.

F. Doubt‑Solving & Discussion (if extended)

• Open‑floor discussion on participants - real‑life scenarios.
• Typical doubts:
• Can ITC be claimed on RCM if the supplier is registered later?
• How to treat RCM where part of services are for exempt supplies?
• Reversal entries for ineligible‑ITC and interest implications.
