The income tax department is in the process of upgrading software applications. It is for information of PAN applicants that PAN allotment by Income Tax Department will remain suspended between 05.10.2015 to 09.10.2015 due to PAN data migration activity. However, PAN applications, through on- line and off-line modes, will continue to be received by PAN service centers of M/S NSDL and M/s UTIITSL. The back log of PAN application will be cleared within three days.
