Sri Lanka’s tax system has undergone significant reforms in recent years as the government strengthened revenue collection and modernized tax administration. Whether you are a Sri Lankan resident, business owner, investor, expatriate, or an Australian with interests in Sri Lanka, understanding the Sri Lankan tax system is essential for compliance and effective tax planning.
The tax system is primarily administered by the Inland Revenue Department (IRD) and consists of direct taxes (income taxes) and indirect taxes (such as VAT). The principal legislation governing income tax is the Inland Revenue Act No. 24 of 2017, which remains the foundation of Sri Lanka’s income tax framework. [Inland Rev…reciation) | PDF]
