Section 49 - Payment of tax, interest, penalty and other amounts.

Electronic cash ledger: prescribed electronic payments are credited and usable for GST liabilities under prescribed conditions.

Section 49 requires deposits made by prescribed electronic modes to be credited to the electronic cash ledger and self-assessed input tax credit to the electronic credit ledger; ledger balances may be used, subject to rules, to pay tax, interest, penalty, fees and other amounts, with residual balances refundable. The provision mandates maintenance of an electronic liability register, prescribes the sequential order for discharging dues across periods and categories, sets cross-utilisation priorities and prohibitions among integrated, central and State/Union territory tax credits, and creates a rebuttable presumption that tax paid has been passed to the recipient.
