Electronic Credit Ledger rules require crediting input tax credit, debiting for liabilities and refund claims, with re-credit on refund rejection. The Electronic Credit Ledger must be maintained in FORM GST PMT-2 on the Common Portal and credited with every input tax credit claim. It shall be debited for discharge of liabilities and for amounts claimed as refund of unutilized balance. If a refund claim is rejected wholly or partly, the debited amount to the extent of rejection shall be re credited by the proper officer by order in FORM GST PMT-2A; a refund is deemed rejected if the appeal is finally dismissed or the claimant undertakes not to appeal.
