Aadhaar PAN rules: Currently, quoting of PAN is mandatory for cash transactions exceeding Rs. 50,000

Did you know that a Permanent Account Number (PAN) is generated automatically if an income tax return (ITR) is filed by quoting an Aadhaar number? The Income Tax Department said last month that a PAN will be generated automatically if a person files the ITR is filed using Aadhaar. Current income tax laws allow an individual to furnish Aadhaar interchangeably with PAN. That means instead of the 10-character PAN, a 12-digit Aadhaar number or Unique Identity Number can be quoted under the tax laws. Meanwhile, the government on Saturday extended the due date for linking PAN or Permanent Account Number with Aadhaar by three months.

A person not having a PAN furnishing Aadhaar for filing an income tax return "shall be deemed" to have applied for allotment of PAN, according to the Central Board of Direct Taxes (CBDT), the apex policymaking body for the Income Tax Department. In other words, such persons will not be required to apply for a PAN or submit any more documents. The rule has come into effect from September 1, according to the taxman.
