The Institute of Chartered Accountants of Sri Lanka (CA Sri Lanka) has presented a comprehensive set of proposals to the government for the upcoming National Budget 2027, calling for a more efficient, equitable and sustainable approach to revenue mobilisation.
At a recent press conference outlining its recommendations, the Institute emphasised the importance of strengthening tax compliance, accelerating digital transformation and bringing more economic activity into the formal sector, rather than relying excessively on increases in statutory tax rates.
The proposals were formally submitted in September 2026 to Dr. Harshana Suriyapperuma, Secretary to the Ministry of Finance. They are built around three key objectives: mobilising additional revenue without over-reliance on higher tax rates, modernising tax administration to encourage voluntary compliance, and strengthening Sri Lanka’s investment, business and institutional environment to support sustainable economic growth.
Highlighting structural weaknesses in the country’s existing revenue framework, CA Sri Lanka noted that Sri Lanka remains heavily dependent on indirect taxation. This places a disproportionate burden on ordinary consumers and can encourage economic activity to remain outside the formal sector.
To address these challenges, the Institute proposed a clear sequence of priorities for revenue mobilisation, arguing that increases in statutory tax rates should be considered only after other available measures have been exhausted.
These priorities include improving compliance with existing tax laws, identifying untaxed economic activities, reducing revenue leakages across government departments, broadening the tax base through digitalisation and improved data integration, and reviewing and rationalising existing tax exemptions.
CA Sri Lanka believes that following this approach would enable the government to strengthen revenue collection while minimising unnecessary financial pressure on compliant taxpayers and businesses.
To support these reforms, the Institute recommended establishing an integrated data ecosystem to improve the efficiency and accuracy of tax administration. A central element of this proposal is the creation of a National Taxpayer Information Network (NTIN) and a Universal Business Identification Number (UBIN).
These mechanisms would facilitate the integration of information from Sri Lanka Customs, VAT transaction records, corporate ownership registries, financial accounts, property records and other public-sector databases. Better coordination among these data sources could help authorities identify gaps in tax compliance, improve taxpayer identification and reduce revenue leakages.
Through its Budget 2027 proposals, CA Sri Lanka has called for a strategic shift towards a more digitally enabled, compliance-focused tax system that strengthens public revenue while supporting investment, business confidence and long-term economic stability.
