Worked examples — five live scenarios
Example 1 — Fresh registration ITC claim
Facts: New taxpayer becomes liable for registration on 1-Sep-2025. Registers within 30 days. Stock on 31-Aug Rs. 5 lakh + GST Rs. 90,000.
Analysis: Sub-s. (1)(a) — eligible for ITC on stock day before liability. ITC-01 within 30 days. CA / CMA certification (claim >Rs. 2 lakh). Invoice-date within 1 year of 1-Sep-2025.
Result: Rs. 90,000 ITC claimed via ITC-01.
Example 2 — M&A ITC transfer
Facts: Company A merges into Company B. Company A's unutilised ITC Rs. 5 lakh.
Analysis: Sub-s. (3) — ITC transfer through ITC-02. Company A files ITC-02; Company B accepts. Liability transfer documentation. CA / CMA certification.
Result: ITC transferred via ITC-02 framework.
Example 3 — Composition opt-in reversal
Facts: Regular taxpayer opts for composition effective 1-Apr-2025. Stock Rs. 10 lakh + ITC Rs. 1.8 lakh. Capital goods ITC Rs. 5 lakh (bought 8 quarters ago).
Analysis: Sub-s. (4) — reversal via ITC-03 within 60 days. Stock reversal Rs. 1.8 lakh. Capital reversal = Rs. 5 lakh × (1 - 40%) = Rs. 3 lakh (Rule 40 — 8 × 5% = 40% reduction). Total reversal Rs. 4.8 lakh.
Result: ITC-03 reversal operative.
Example 4 — Capital goods disposal
Facts: Capital good bought 16 quarters ago at Rs. 10 lakh + ITC Rs. 1.8 lakh. Sold for Rs. 3 lakh.
Analysis: Sub-s. (6) — higher of (a) Rule 44 reduced ITC = Rs. 1.8 lakh × (1 - 80%) = Rs. 36,000 OR (b) tax on Rs. 3 lakh sale = Rs. 54,000. Higher — Rs. 54,000. Pay Rs. 54,000.
Result: Sub-s. (6) disposal discipline.
Example 5 — 1-year time-bar
Facts: Voluntary registration 1-Oct-2025. Stock from invoice dated 15-Jun-2024 (16 months ago).
Analysis: Sub-s. (2) — 1-year time-bar. Invoice 15-Jun-2024 is older than 1 year before 1-Oct-2025. ITC denied on this stock.
Result: 1-year time-bar operates.
