Sri Lanka's tax authority has declared that businesses and individuals must obtain a valid Taxpayer Identification Number (TIN) Certificate to conduct a range of critical transactions, effective from November 1.
The Inland Revenue Department (IRD) issued the directive to ensure enhanced compliance with tax regulations and improve financial accountability across various sectors. The mandatory requirement will apply to key commercial and financial activities, though specific transaction categories were not detailed in the announcement.
The move reflects the government's broader push to strengthen tax administration and broaden the revenue base. By requiring TIN Certificates for essential transactions, authorities aim to create a more comprehensive record of economic activity and reduce tax evasion.
Businesses and individuals are advised to obtain their TIN Certificates before the November 1 deadline to avoid disruptions to their operations. The IRD is expected to provide further guidance on the implementation process and applicable transaction categories in coming weeks.
