A TIN is not the same as income tax registration. That is a separate step for people with income above the threshold. Foreign nationals use a valid passport and proof of a local address.

Questions

How do I get a TIN number in Sri Lanka?

Apply on IRD e-Services under TIN Registration with a PDF of your NIC, both sides. After review, IRD emails a certificate with your TIN and a one-time PIN.

How do I find my TIN if I already registered?

Open the IRD verification page, enter your NIC, then your mobile number or email, send the OTP, enter it and click Search. Your TIN is shown on screen. No office visit is needed.

Can I apply on paper?

Yes. IRD’s 2023 notice says to fill in the application form and hand it to the Primary Registration Unit on the 2nd floor of the head office, or to the nearest regional or metropolitan office. IRD advises the online route.

Is there a fee?

IRD’s FAQ answers “No” for the application form and the service.

I lost my certificate. What do I show?

IRD’s FAQ says the certificate is issued only once. Its notice says a printout of the verification result, clearly showing your NIC and TIN, may also be accepted. Call 1944 if an office asks for more.

Does a TIN mean I must pay income tax?

No. IRD treats them as two steps: the TIN comes first, and income tax registration is for people liable because of their income. See our page on the income tax return.
