Credit Migration explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Unutilised credit is often the largest asset a restructuring moves — and it moves only if a condition about liabilities is satisfied and a form is filed.
The cornerstone provision for credit migration
Section 18(3) of the CGST Act is the cornerstone provision for input tax credit transfer in restructuring, permitting a registered person to transfer unutilized credit in cases of sale, merger, demerger, amalgamation, lease or transfer of business, provided there is a specific provision for the transfer of liabilities.
Read the proviso carefully: credit transfers provided there is a specific provision for the transfer of liabilities.
Credit is a claim against the exchequer that arose because tax was paid on inputs used in a business. Section 18(3) allows it to follow the business — but only where the business's liabilities follow too.
Without that condition a transferor could move all its credit to a buyer while retaining its tax liabilities, leaving the department with an entity that owes tax and holds no credit against it.
The condition also explains why the mechanism requires a professional certificate rather than a self-declaration. Form GST ITC-02 under Rule 41 requires the transferor to furnish details of the reorganization and obtain a certificate from a practicing Chartered Accountant or Cost Accountant confirming the transfer of liabilities, following which the transferee accepts the filing on the common portal and the credit is reflected in its electronic credit ledger.
The certificate is directed at exactly the point the proviso turns on — not at the quantum of credit, but at whether liabilities moved with it.
Credit migration on a demerger: the apportionment ratio
In a demerger, credit is apportioned in the ratio of the value of assets transferred to the resulting entities as specified in the scheme, with the value of assets for this purpose meaning the value of the entire assets of the business, irrespective of whether input tax credit was actually availed on them.
That last clause is counter-intuitive and consequential. The denominator includes assets on which no credit was ever availed — land, exempt supplies, blocked items. A demerged undertaking rich in such assets therefore takes a larger share of credit than its credit-generating activity would suggest, and vice versa.
The rules around credit migration
| Provision | What it governs |
|---|---|
| Rule 41 | The Form GST ITC-02 mechanism for transfer on reorganisation |
| Rule 41A (inserted 2019) | Credit allocation on obtaining separate registration for multiple places of business within a State, with details furnished within thirty days of the separate registration and credit transferred in the ratio of assets held by each newly registered place of business at the time of registration |
| Rule 42 | Apportionment of common credit for entities that make both taxable and exempt supplies, requiring demerged entities with exempt supplies to reverse proportionate credit on an ongoing monthly basis using the prescribed formula |
| Sections 18(4) and 18(5) with Rule 44 | Reversal of input tax credit on inputs and capital goods when a registered person switches to the composition scheme or when their supplies become wholly exempt; for capital goods, calculated on a pro-rata basis based on their remaining useful life |
Two gaps and a timing trap in credit migration
- Business conversion. The GST law contains no specific provision addressing the transfer of input tax credit in cases of mere business conversion, which continues to generate interpretational disputes.
- Partial transfers. A litigation risk arises where only select assets, rather than the entire business, are transferred, since such a transfer may be recharacterized as a taxable supply notwithstanding an intended going-concern structuring.
- Invoices at the appointed date. Pending or unavailed invoices as on the appointed date are a frequent source of dispute: any input tax credit on invoices issued to the transferor prior to the appointed date should, as far as possible, be identified and availed by the transferor before that date, since credit not availed in time by the transferor cannot straightforwardly be picked up by the transferee thereafter.
Why the timing trap bites
Credit on an invoice belongs to the person to whom the invoice was issued. Once the appointed date passes, the transferor may no longer be the entity operating the business, and the transferee is not the addressee of the invoice — so neither is comfortably placed to claim it.
The practical answer is a pre-appointed-date sweep: identify every invoice on which credit has not been availed and avail it while the transferor can still do so.
Common mistakes
- Filing ITC-02 without a specific provision for the transfer of liabilities.
- Apportioning demerger credit migration by reference to credit-bearing assets only.
- Missing the thirty-day window under Rule 41A after separate registration.
- Leaving unavailed invoices for the transferee to pick up after the appointed date.
