🔹 Introduction

Input Tax Credit (ITC) is the backbone of GST, but not all ITC claimed can be retained permanently. In many cases, GST law requires reversal of ITC to ensure credit is available only for eligible business use. Non-reversal may lead to interest, penalty, and notices under Sec. 74A. This guide explains rules, cases, and compliance for ITC reversal in FY 2024-25.

(Reference: Sec. 16, 17, 18 of CGST Act; Rule 37, 42 & 43 of CGST Rules; CBIC circulars till 2025)

🔹 Step-by-Step ITC Reversal Process

📌 Step 1: Identify cases where reversal required (blocked ITC, exempt supplies, non-payment, etc.).
📌 Step 2: Calculate reversal amount as per Rule 42/43 formula.
📌 Step 3: Report reversal in GSTR-3B Table 4(B).
📌 Step 4: Pay interest if applicable.
📌 Step 5: Reclaim ITC later (if eligible) once conditions satisfied (e.g., supplier paid after 180 days).

🔹 Practical Examples

Example 1: Non-Payment to Supplier
Company avails ITC of ₹1,00,000 on invoice but fails to pay supplier within 180 days. ITC of ₹1,00,000 reversed in GSTR-3B with interest. Once supplier paid, ITC re-availed.

Example 2: Exempt & Taxable Turnover
A business has turnover ₹1 crore, out of which ₹20 lakh is exempt. Common ITC ₹5 lakh. ITC to be reversed = 20% × ₹5 lakh = ₹1 lakh.

Example 3: Capital Goods Partly for Exempt Use
Company buys machine worth ₹10 lakh with GST ₹1.8 lakh. 30% use for exempt goods. ITC reversal = ₹54,000 spread over 5 years.

🔹 Common Mistakes

• Not reversing ITC on non-payment within 180 days.

• Claiming full ITC on common inputs without Rule 42 adjustment.

• Ignoring capital goods ITC reversal requirement.

• Not reporting reversal in GSTR-3B Table 4(B).

🔹 Penalties & Legal Provisions

• Wrongful ITC claim → Penalty under Sec. 74A (from FY 2024-25).

• Interest @18% on delayed reversal.

• Notices issued under scrutiny if ITC reversal missed.

🔹 Best Practices

• ✅ Maintain ITC reconciliation monthly.

• ✅ Track 180-day supplier payment rule.

• ✅ Use ERP/accounting software for Rule 42/43 calculations.

• ✅ Conduct internal ITC audits quarterly.
