Revenue Statistics in Asian Countries: Trends in Indonesia, Malaysia and the Philippines shows that the tax-to-GDP ratio has grown steadily since 2000 in all three countries, but has remained relatively stable in recent years.
In 2013, Indonesia had a tax-to-GDP ratio of 13.1%, which was slightly lower than the 16.2% reported in the Philippines and the 16.9% reported in Malaysia. The three countries’ tax levels were significantly below those of OECD countries in the region such as Korea, where the tax-to-GDP ratio was 24.3%, or Japan, where it was 29.5%, and well below the OECD average of 34.1%."
