When opening a Trading and Demat account, whether as an individual or a non-individual, it is mandatory to declare your Tax Identification Number (TIN). This number serves as the reference by which your tax status is linked in your country of residence. The TIN varies from country to country and may have different names. For instance, in India, it is called the PAN (Permanent Account Number), while in the US, it is known as the SSN (Social Security Number) or EIN (Employer Identification Number).

Key Points:

• Mandatory Declaration: You must declare your TIN when opening an account.
• Ongoing Requirement: Any changes to your TIN must also be reported and updated.

This ensures compliance with tax regulations and proper linking of your financial activities with your tax identity.
