The Organisation for Economic Co-operation and Development (OECD) recently published a report on taxA tax is a mandatory payment or charge collected by local, state, and national governments from individuals or businesses to cover the costs of general government services, goods, and activities. revenue statistics in selected Asian and Pacific countries. The report, covering 24 tax jurisdictions, provides tax revenue data from 1990 to 2019 and includes a section on nontax revenue data for selected Asian and Pacific economies. Additionally, a special feature co-authored by the Asian Development Bank (ADB) and the OECD explores the role of tax policy and administration in mobilizing domestic resources to help developing countries recover after the COVID-19 pandemic and associated economic crisis.
As economies are starting to recover and growth is expected to rebound in the region during 2021, Asian and Pacific countries should start exploring changes to their fiscal tax policies while carefully evaluating the optimal time for eliminating fiscal stimulus and temporary tax relief.
Tax revenue as a percent of GDP (tax-to-GDP ratio) varies significantly across the countries covered, with the highest ratio in Nauru (48.2 percent) and the lowest ratio in Bhutan (10.3 percent). While all countries covered, with the exception of Nauru, have a lower tax-to-GDP ratio than the OECD average (33.8 percent), 7 of the countries’ ratios are higher than the Latin America and the Caribbean average (22.9 percent). Additionally, 10 countries have higher tax-to-GDP ratios than the African average (16.6 percent).
Between 2018 and 2019, tax-to-GDP ratios fell in 15 of the 24 countries. China, Fiji, Samoa, Bhutan, the Cook Islands, and the Solomon Islands registered a reduction of more than 1 percentage-point. In the Solomon Islands, the tax-to-GDP ratio fell by 3.6 percentage-points. Bhutan and the Cook Islands also experienced a significant decrease of 2.3 and 3 percentage-points, respectively, as the 2019 fiscal year included part of the 2020 data, reflecting the early impact of the COVID-19 pandemic on the economy.
Only seven countries experienced increases in their ratios in 2019 relative to 2018. Nauru and Tokelau saw the largest increases in their ratios, at 12.9 percentage-points, and 1.2 percentage-points. For the remaining five countries the increases were less than 1 percentage-point.
Sources of Tax Revenue
Taxes on goods and services (including value-added taxes and other taxes on goods and services) make up a significant share of total tax revenue in most countries covered. Almost 57 percent of the Pacific Islands’ tax revenue comes from taxes on goods and services, compared to between 32 and 44 percent in the OECD and Asia,.
While OECD countries on average raise a large share of their tax revenue from income taxes and social security contributions, these two types of taxes play a less significant role in Pacific Islands and Asia.
Corporate income taxA corporate income tax (CIT) is levied by federal and state governments on business profits. Many companies are not subject to the CIT because they are taxed as pass-through businesses, with income reportable under the individual income tax. es raise almost 23 percent of total tax revenue in Asia, compared to less than 10 percent in the OECD and 8 percent in the Pacific Islands.
The increase in public debt, due to the fiscal measures adopted to mitigate the impact of the COVID-19 pandemic and the decrease in tax revenues, are putting a strain on Asian-Pacific countries’ public finances. Countries in the Asia-Pacific region face different challenges in their capacity to mobilize domestic revenue depending on the structure of their economy. Additionally, the strong GDP growth that countries in the Asia-Pacific region have faced over the past decades was not accompanied by a similar increase in tax revenues. Therefore, according to the OECD, potential policy measures for the post-pandemic economic recovery should focus on effective tax reforms, reduction of the informal economic activity, digital transformation of tax administration, and active participation in international tax initiatives.
As economies begin to grow again, policymakers should focus on tax reforms that reduce the economic burden of taxation while also raising sufficient revenue. The focus should be on streamlining consumption taxA consumption tax is typically levied on the purchase of goods or services and is paid directly or indirectly by the consumer in the form of retail sales taxes, excise taxes, tariffs, value-added taxes (VAT), or an income tax where all savings is tax-deductible. es while minimizing the distortionary effects of taxes on businesses and workers.
