PAN Aadhaar linking: transitional deferral of adverse consequences for inoperative PANs while fee liability remains applicable. Requirement to link PAN with Aadhaar makes PANs inoperative if Aadhaar is not intimated by the notified date; failure attracts a prescribed fee when Aadhaar is later intimated and ordinarily triggers the legal consequences of an inoperative PAN when it is furnished or quoted. The Board provides a one year transitional deferral of those negative consequences, subject to payment of the linking fee, to mitigate disruption to filing, refunds, withholding and KYC processes.
