A PAN (Permanent Account Number) card is a unique 10-character ID issued by the Indian Income Tax Department. It is essential for financial transactions and tax filing in India. You can apply for a PAN card online through NSDL or UTIITSL websites or offline at authorized centers. The application requires documents like proof of identity, address, and date of birth. After verification, the PAN card is sent to your address. It is mandatory for filing income tax returns, opening bank accounts, and investing. Having a PAN card helps you comply with tax laws and makes financial processes easier.
