PHNOM PENH – Tax And Spend has rarely been part of the Southeast Asian governance lexicon. And judging by the region’s dismal tax-to-gross domestic product (GDP) ratios, it doesn’t look like that will be changing anytime soon. Newly published revenue statistics compiled by the Paris-based Organisation for Economic Co-operation and Development (OECD) show that the five biggest Southeast Asian economies have ratios of half or less than the 2017 OECD average of 34.2%, though most countries in the region showed small increases in revenues compared with the previous year. The OECD defines the tax-to-GDP ratio as “total tax revenue, including social security contributions, as a percentage of GDP”. While more prosperous countries in Southeast Asia’s vicinity such as Australia, Japan and New Zealand all come in around the 30% mark, Southeast Asia’s own numbers were much lower, with Indonesia at 11.5%, Malaysia on 13.6 and Singapore only slightly above on 14.1. This last number in particular seems surprisingly low given that Singapore’s economy more resembles higher-tax Western counterparts than its neighbours in Southeast Asia.
