TINs serve to help tax departments link financial records, filings, and transactions to specific individuals or organisations. In India, the PAN acts as the TIN under the Income Tax Act. Overseas, countries may issue TINs for residents and non-residents—such as the US ITIN, Canadian SIN, or EU TINs—to facilitate international tax compliance.
TIN versus ITIN and PAN
The terminology can vary:
Each identifier is valid only within its issuing jurisdiction but often used jointly for international tax reporting, such as under FATCA or CRS.
Importance of TIN for investors
TINs are often mandatory when:
Filing income tax returns
Investing in securities (stocks, F&O, mutual funds)
Opening bank or Demat accounts
Making foreign investments
Complying with regulatory requirements like KYC or FATCA reporting
Having a valid TIN ensures accurate tracking and prevents regulatory delays or penalisation.
