Sri Lanka tax administration has delivered sharp revenue gains under the IMF-backed fiscal programme, but mounting concerns are emerging over whether enforcement practices align with principles of justice and the rule of law. As collections accelerate, questions about due process, oversight, and institutional accountability have intensified.
Sri Lanka tax administration faces scrutiny over enforcement and rule of law
Since May 2022, Sri Lanka has introduced new taxes, revised rates, and expanded the tax base to stabilise public finances following sovereign default and repeated balance-of-payments crises. The number of income tax files has more than tripled between 2022 and 2024, while VAT registrations doubled over the same period. Tax revenue surged 55 percent in 2023, rose another 25 percent in 2024, and expanded further in the first half of 2025. These outcomes have been widely commended as evidence of fiscal consolidation.
Yet the expansion of state revenue has also amplified scrutiny of how power is exercised by the Inland Revenue Department. Analysts argue that the core issue is not administrative efficiency but the balance between coercive authority and individual rights. Taxation, unlike voluntary contributions, is enforced by law and backed by penalties, asset seizures, and in some cases personal liability for company officers. Such authority requires institutional constraints to prevent overreach.
Legal scholar Ravi Ratnasabapathy contends that when tax demands become excessive or arbitrary, they risk resembling confiscation rather than legitimate revenue collection. He notes that if tax rates or assessments compel disposal of property merely to satisfy obligations, the distinction between taxation and expropriation becomes blurred. In economic terms, such dynamics can distort capital allocation, discourage reinvestment, and suppress long-term growth.
The Sri Lanka tax administration operates within a self-assessment framework, under which taxpayers declare liabilities subject to review. However, practitioners report instances where returns are rejected without adequate reasoning, margins deemed “insufficient,” or expenses disallowed without detailed justification. Case law has established that assessments must be supported by proper grounds rather than broad conclusions, yet enforcement practices sometimes diverge from this standard.
Redress mechanisms present another structural challenge. Appeals proceed sequentially from an internal administrative review to the Tax Appeals Commission and then to the courts. Administrative reviews may take up to two years, and while the Commission is statutorily independent, further appeals by revenue authorities can prolong disputes for years. During this period, interest accrues at 1.5 percent per month on disputed income tax under the 2017 Act, compounding financial pressure. Deposits of up to 25 percent of disputed tax are required before appeals proceed, raising access-to-justice concerns for smaller firms.
Comparative institutional models illustrate alternative safeguards. In the United Kingdom, HM Revenue & Customs operates as a non-ministerial department accountable to Parliament but insulated from direct political control. Oversight includes independent board members and parliamentary scrutiny through committees such as the House of Commons Public Accounts Committee. These mechanisms reinforce transparency and procedural fairness, ensuring that enforcement authority remains subject to external challenge.
Sri Lanka lacks equivalent multi-layered oversight. Analysts argue that procedural safeguards, though embedded in statute and the Taxpayer Charter, remain weak in implementation. The Asian Human Rights Commission has repeatedly highlighted deterioration in the rule of law, a concern echoed by global indices. In 2025, the World Justice Project ranked Sri Lanka 74th out of 143 countries, underscoring institutional fragility.
At the operational level, businesses report intrusive audits requiring extensive reconciliations and documentation. Minor discrepancies may trigger disproportionate penalties, and in some cases historical assessments spanning more than a decade have been reopened. The absence of finality creates uncertainty, complicating financial planning and discouraging investment. One investor described retreating from active business operations into passive income after repeated audits, illustrating how enforcement intensity can alter economic behaviour.
Customs administration presents parallel concerns. Expanded audit authority over Board of Investment firms has introduced new compliance risks for exporters dependent on predictable logistics. In a recent case, penalties exceeding 100 times the duty were imposed for a technical miscalculation, contrasting with more proportionate caps in jurisdictions such as Singapore.
From a macroeconomic perspective, the tension between revenue mobilisation and capital preservation is critical. While fiscal consolidation was unavoidable after external default, excessive reliance on income and savings-based taxation risks eroding investible capital. Economic history offers cautionary lessons. Post-war Britain and pre-war Germany experienced prolonged stagnation under high tax burdens combined with monetary instability, whereas several East Asian economies sustained rapid growth with relatively moderate tax rates and stable currencies.
Recent policy moves have also raised competitiveness concerns. The imposition of a 15 percent tax on service exports in April 2025 has coincided with downsizing in segments of the IT and business process outsourcing sector. Firms exposed to international competition face thin margins and limited ability to absorb higher effective tax rates. Unlike domestic import-substituting businesses, exporters cannot easily offset increased burdens through protectionist measures.
The broader political economy question is whether aggressive enforcement in a weak institutional environment ultimately undermines the tax base it seeks to expand. If taxpayers perceive assessments as arbitrary and appeals as inaccessible, voluntary compliance deteriorates. This can trigger a cycle in which lower investment leads to weaker growth, shrinking revenue potential and prompting further rate increases.
The Sri Lanka tax administration thus stands at a structural crossroads. Strengthening fiscal capacity is essential for debt sustainability and public services, yet legitimacy depends on transparent procedures, enforceable rights, and credible oversight. Without institutional reform to reinforce due process, the boundary between necessary revenue collection and administrative overreach risks becoming increasingly contested.
