TDS on immovable property: pay immediately online via Protean TIN with PAN validation and bank net banking confirmation. E payment of TDS on immovable property via Protean TIN requires completing the property TDS form, entering purchaser and seller PANs and transaction details, and selecting immediate payment. The system validates PANs against the PAN Master and blocks payment if PAN is not found or mismatches occur; PAN/name corrections cannot be made online and require separate PAN change procedures. After confirmation the taxpayer receives an acknowledgement number, is redirected to bank net banking to complete payment, and on success obtains an electronic challan counterfoil as proof of payment.
