The Organisation for Economic Co-operation and Development (OECD) has revealed the tax-to-Gross Domestic Product (GDP) ratio for almost every country in the world. Indonesia ranks among the bottom three, with a low proportion.
Nauru holds the top spot with a 47.5% ratio. Nauru was once a very wealthy small nation, even having exempted its citizens from taxes.
Second is the average of the 38 OECD member countries, at 33.5%. New Zealand is third, with a 32.2% ratio.
Meanwhile, the average tax ratio for Asia-Pacific countries is 19.1%. Indonesia, in the bottom three, recorded a tax ratio of only 10.1%.
Below Indonesia are Bhutan (8.9%) and Laos (8.9%).
The OECD notes that Indonesia's tax ratio decreased by 1.5 percentage points, from 11.6% in 2019 to 10.1% in 2020. This is the lowest figure since 2007.
"From 2007 to 2020, Indonesia's tax ratio decreased by 2.1 percentage points, from 12.2% to 10.1%. The highest ratio during this period was 13% in 2008, and the lowest was 10.1% in 2020," the OECD wrote in its report.
According to *Klik Pajak*, the tax ratio is a tool to assess whether the amount of tax collected in a given period in a country is commensurate with its national income.
A narrow definition of the tax ratio includes Income Tax (PPh), Value Added Tax (PPN/PPnBM), Land and Building Tax (PBB), Customs and Excise duties, and other taxes. A broader version also includes the total value of non-tax state revenues (PNBP), natural resources (SDA) from oil and gas, and mineral and coal mining (minerba), against nominal GDP.
The OECD uses a broader tax ratio reference than usual, including social security contributions.
Several factors highlight the importance of the tax ratio for a country:
(a) It serves as an indicator of tax compliance in Indonesia. A low tax ratio percentage indicates that tax compliance is still low compared to other countries.
(b) A low tax ratio hinders the achievement of sustainable development.
(c) A tax ratio can create a fair tax system.
