Payment of income tax via Challan 280 requires PAN, itemised tax amounts, and bank BSR/date/serial acknowledgement. Challan 280 prescribes the process for depositing corporate and non corporate income taxes, requiring PAN, taxpayer name and address, selection of tax head and payment type, and itemised amounts (income tax, surcharge, education cess, interest, penalty, others). Banks must record payment details and issue an acknowledgement with the branch BSR code, deposit date and challan serial number for use in the return. Separate challans must be used for each payment type, PAN is mandatory, and the challan is not for TDS deposits.
