The deadline to link PAN and Aadhaar cards in India is approaching fast, with December 31 set by the Central Board of Direct Taxes (CBDT). It is obligatory that these two crucial documents should be connected to allow keeping PAN valid to file taxes on income, to make bank transactions and other financial requirements. Millions of taxpayers are hustling to complete this process and it is important to know how to connect your PAN with Aadhaar in the most efficient and fast way possible.
PAN (Permanent Account Number) is a 10 digits alpha-numeric number issued by the Income Tax Department, which is required in filing tax returns, opening bank accounts, as well as in high-value transactions. On the contrary, Aadhaar is a 12-digit unique identity number given by UIDAI, founded on demographic and biometric data. Both the documents are required to be linked by the government to avoid tax evasion, curb the use of fake PAN and unify the system of identity. The inability to connect can make your PAN unusable, which could disrupt taxing and refunding operations, as well as transactions.
UIDPAN <12-digit Aadhaar Number 10-digit PAN Number and send it to your registered mobile number 567678 or 56161. The acknowledgement SMS will be sent to you once the linking is successful.
Provided that you do not link PAN and Aadhaar before the end of December, your PAN will become inoperative. This may make income tax returns to be rejected, tax refund blocked, bank transactions limited, TDS deductions increased and trouble opening a financial account. Connecting ahead of time guarantees the unavailability of tax and financial services.
