Rethinking tax policy in Sri Lanka

• The case for adhering to tax principles

Many Sri Lankan budget speeches are essentially discussions on Government expenditure. Revenue proposals are often introduced piecemeal before the budget and frequently fail to align with basic principles of taxation. 

Under the current International Monetary Fund (IMF) programme, Sri Lanka has committed to achieving a revenue target of 15% of Gross Domestic Product (GDP) by 2025, increasing to 15.5% by 2026. Additionally, a primary balance target of 2.3% in 2025 must be met and maintained. 

While we have already exceeded the primary balance target, this achievement has come at the cost of cutting capital expenditure, which will likely impede long-term growth.

Tax revenue has met targets, primarily through record-high import tariffs collected at the border by Sri Lanka Customs, amounting to Rs. 1,500 billion. However, relying on such high border tariffs impacts both the cost of living and the cost of raw materials, adversely affecting exports and local production.

The need for adhering to tax principles

It is crucial that the Government prioritises adherence to fundamental principles of taxation when implementing revenue measures. Over-reliance on border taxes is not a sustainable strategy for achieving a higher tax-to-GDP ratio.

Why border taxes are problematic

Generating revenue through border taxes disproportionately affects importers, as they incur significant costs upfront, even before generating profits. In contrast, profit-based taxes are levied only after profits are realised, making them less burdensome from a cash flow perspective. The time value of money amplifies the impact of upfront border tariffs on profitability.

Sri Lanka’s import basket comprises approximately 80% intermediate and capital goods, with only 20% being consumer goods. Tariffs on these critical imports drive up production costs, ultimately increasing the price of exports and even domestic goods. For example, the Rs. 65 tariff on rice accounts for about 50% of its production cost, leading to a nationwide increase in meal costs by approximately the same margin.

A tax base built on three pillars

Globally, taxes are traditionally levied on three bases:

What you earn (e.g. income tax, corporate tax)

What you buy (e.g. Value-Added Tax, or VAT)

What you own (e.g. property tax)

Principles for an effective tax system

Simplicity: Taxes must be simple for taxpayers to understand and for authorities to collect and enforce. Overly complex tax structures with numerous thresholds lead to lower compliance, reduced revenue, and enforcement challenges. A standard and straightforward tax system is key to maximising efficiency and minimising leakage.

Transparency: Transparency in taxation fosters trust and reduces opportunities for corruption. For instance, Sri Lanka’s import tariff system, based on Harmonised System (HS) codes, lacks transparency due to its cascading structure. Similarly, ambiguities in income tax policies create doubts and complications. Transparency is especially critical for tariffs, which, even when necessary, must be clear and predictable.

Neutrality: Taxes should not create winners and losers by favouring or penalising specific industries, products, or sectors. For example, in 2015, Sri Lanka imposed taxes on profits from the previous year, undermining the fairness of the system. The primary purpose of taxation is revenue generation, not market distortion. Lowering tax rates can expand the tax base, ultimately increasing revenue and minimising evasion.

Stability: Tax rates should remain consistent over time to provide predictability for taxpayers. Frequent changes to tax rates, such as the numerous adjustments to VAT in Sri Lanka, create uncertainty, open avenues for corruption, and undermine economic stability. Temporary taxes and tax holidays should also be avoided to maintain consistency and fairness.

Taxes on property: A case for caution

Among all forms of taxation, taxes on property ownership are particularly burdensome. This is because taxpayers often have to forgo another revenue source to meet their property tax obligations. 

If a property generates income, that income is already taxed under income tax laws. Imposing an additional property tax not only constitutes double taxation but also discourages wealth creation. Such policies can deter investment and economic growth, undermining broader development objectives

Balancing revenue generation and expenditure

Sri Lanka urgently needs to increase tax revenue due to its high expenditure, particularly on interest payments, which account for approximately 50% of total expenditure. This is not repayment of debt but merely the cost of servicing bad debt. While room for expenditure cuts is limited due to the predominance of recurrent spending, hard restructuring is necessary to reduce this burden.

Although the Government has achieved a primary surplus by reducing capital expenditure, this strategy will have adverse long-term effects on growth. Therefore, adhering to fundamental tax principles is critical to improving Government revenue sustainably without jeopardising the country’s economic prospects.
