What is a TIN?
A Taxpayer Identification Number (TIN) is a unique identifier issued by the Inland Revenue Department (IRD) of Sri Lanka to individuals and entities for taxation purposes. It serves as your official tax ID and is essential for all tax-related activities, including filing returns, paying taxes, and accessing e‑services.
Starting January 1, 2024, every individual aged 18 years or older is required to register for a TIN. This applies to all citizens, regardless of whether they have taxable income or not. Having a TIN simplifies interactions with the IRD and is a prerequisite for many financial and business activities.

- Businesses (sole proprietorships, partnerships, companies)
- Organizations and institutions liable to any tax

Note: Even if you have no income, you are still required to obtain a TIN. Registration is mandatory by law.
