Quoting of the Permanent Account Number (PAN) has become imminent in almost all big purchases that one makes. The need to provide the PAN even arises at the time of taking a loan whether it is a car loan or a home loan. PAN is supposed to be a unique number and no two individuals or entities can hold the same PAN number. Further, the income tax rules also do not allow the same individual to hold two or more different numbers. A person cannot hold more than one PAN. In case one applies for the PAN card but it gets delayed, the indiviudal re-applies and ends up receiving two PAN cards with different numebrs. A penalty of Rs. 10,000 is liable to be imposed under section 272B of the Income Tax Act, 1961 for having more than one PAN. If a person has been allotted more than one PAN then he should immediately surrender the additional PAN cards. In case one is using different PANs for different purposes like one for the demat account and another for filing my Income-tax return and payment of taxes, then only one of them should be retained, preferably the one used for Income-tax purpose and the other number should be surrendered immediately. Further, the institution where the latter number ( the surrendered one) has been quoted should be informed of the correct PAN. If one loses the PAN card, it is always better to apply for a duplicate one rather than applying for a new one. In case, one doesn\u2019t know the PAN number, it can be known by using the facility of \u201cKnow Your PAN\u201d provided by the Income Tax Department on its website. Here, the person can know the PAN online by providing details like Name, Father's Name and Date of Birth. And once the PAN is known, the duplicate PAN card can be applied.
