Having more than one PAN (Permanent Account Number) card is illegal according to Indian law. It is mandatory for individuals and entities to have only one PAN card, and holding multiple PAN cards is considered fraudulent.

If an individual is found to have more than one PAN card, it can result in several negative consequences. The Income Tax Department may initiate legal action against the individual, which can result in penalties and fines. The individual may also face difficulties in filing their income tax returns and may be unable to receive tax refunds or claim tax deductions.

In addition, having multiple PAN cards can lead to confusion in financial transactions, and the individual may end up paying more taxes than necessary or may have discrepancies in their financial records.

Therefore, it is important to ensure that you have only one PAN card and to surrender any additional PAN cards that you may have obtained by mistake or otherwise. You can surrender additional PAN cards by submitting a request to the NSDL or UTIITSL, the two authorized agencies responsible for PAN card issuance and management in India.
