In Sri Lanka, obtaining a TIN (Taxpayer Identification Number) has become mandatory for all citizens and businesses. Whether you need it for banking services, vehicle registration, or submitting your Google AdSense W-8BEN tax form, having your TIN readily available is essential.

However, due to heavy website traffic and system updates on the Inland Revenue Department (IRD) portal, searching for your TIN directly using your NIC (National Identity Card) is currently unavailable. When attempting to verify online, the portal requests a Document Identification Number (DIN), which most individuals do not possess.

Instead of wasting time navigating the online portal, here are 2 fast and simple methods to retrieve your TIN number within 2 minutes.
