This article provides an overview of the current tax system in Sri Lanka as part of a series discussing potential tax reforms.

Sri Lanka is recovering from the worst economic crisis in its history. Continuous high fiscal deficits due to insufficient government revenue to finance growing government expenditure has resulted in an unsustainable level of debt. This has hindered the government's ability to make capital investments and allocate sufficient funds for essential services such as education and healthcare. A large proportion of revenue (77.7% in 2022) goes to finance interest payments, It is also one of the largest items of recurrent expenditure accounting for 44.5% of recurrent expenditure in 2022.  In comparison expenditure on education, health and social protection (Samurdhi) accounted for only 9.3%, 7.9% and 3.4% of recurrent expenditure, respectively, in 2022.  

Getting back on a path of macroeconomic stability requires a significant boost in revenue.Revenue based fiscal consolidation is one of the key pillars of the stabilization program agreed with the International Monetary Fund (IMF).  The program sets a target of raising tax revenue to 14% of GDP (at the minimum) by 2026 through tax policy reforms and revenue administration reforms.

Taxation as a social contract

The main purpose of taxes is to provide funding for public services. Moreover, it redistributes income through transfer payments to low income households. Taxation is a classic example of the social contract between the citizens of a country and their government but also between citizens. This unwritten agreement influences the willingness of citizens to pay taxes in return for the services they receive from the government. Tax compliance rates in countries indicate a correlation between the payment of taxes and public service delivery. Dissatisfaction with public service delivery is found to be associated with low tax compliance. In Sri Lanka, the state is responsible for providing a wide range of public services such as education and healthcare.  However, the collection of taxes required to finance these public services is woefully inadequate. This could be due to lack of awareness of the role of citizens in the social contract or a lack of quality and availability of public services.  This leads to citizens abandoning public services in favour of the private provision of such services and being unwilling to pay for public services they  feel they don’t use. A robust tax system is necessary for a government to deliver high-quality public services to all its citizens.

The current state of taxes in Sri Lanka

Sri Lanka’s tax revenue collection  has steadily declined from 19% of Gross Domestic Product (GDP) in 1990 to 7.3% in 2022. Although national income has increased over time with  GDP per capita rising from US $ 472 in 1990 to US $ 3,474 in 2022 there has not been a corresponding rise in tax collection (See figure 1).

Revenue collection in the country is also highly skewed, with 69.5% of tax revenue collected from indirect taxes. Undue reliance on indirect taxes is due to the large informal sector which is ‘difficult to tax’.  The direct to indirect tax ratio has consistently remained around 20:80 over time. Although direct taxes as a proportion of total tax has gradually increased from around 15% revenue in 2000 to 31.5% in 2022, as a percentage of GDP it has remained at a low level of around 2% for the last two decades, implying that it has not kept pace with the growth in the economy.

The steady decline in revenue is due to inherent weaknesses in the tax system. One of the key issues is ad hoc policy changes relating to tax rates, thresholds, and exemptions, with little or no economic rationale. The frequency of these tax policy changes worsens the existing compliance issues as well as administrative issues. The resulting loss of government revenue, worsens income inequalities and reduces funds available for essential public services.

These concerns need to be addressed through comprehensive reforms in all 3 broad bases of tax, namely, (1) taxes on earnings such as personal and corporate income taxes; (2) taxes on what is purchased such as the value added taxes (VAT); and (3) taxes on what is owned such as land and property taxes. Identifying the issues in each of these taxes will be key to reforming the tax system and optimizing revenue collection which is vital for ensuring macroeconomic stability.

Conclusion

Building an effective fiscal social contract through taxation is as equally important as addressing the issues prevalent in the current tax system. It requires the government  to use the taxpayers’ money in a responsible and effective manner. Lack of transparency and accountability for the way a government uses the taxes it collects will make it very difficult for the government to convince its citizens to pay their taxes.  On the other hand, citizens are responsible for holding the government accountable and ensuring taxes are utilised for providing good quality public services for the benefit of society as a whole.
