An Aadhaar number can be linked with a Permanent Account Number (PAN) online. The Income Tax Department provides two services to assist assessees in the process of linking the two identification numbers: an SMS-based facility, and an online tool provided on its e-filing portal (incometaxindiaefiling.gov.in). According to latest income tax laws, Aadhaar can be quoted interchangeably with PAN. Meanwhile, the Income Tax Department has set a September 30 deadline for assessees to link their Aadhaar with PAN "unless specifically exempted".
