Funding the Future: Tax Revenue Mobilization in the Pacific Island Countries

Pacific Island Countries (PICs) face daunting spending needs related to achieving the UN Sustainable Development Goals (SDGs) and adapting to the effects of climate change. Boosting tax revenues will need to be an essential pillar in creating the fiscal space to meet SDG and climate-adaptation spending needs. This paper assesses the additional tax revenue that PICs could potentially collect and discusses policy options to achieve such gains. The main objectives of the paper are to (1) review the critical medium-term development spending requirements and available financing options, (2) document the main stylized facts about tax revenues in the PICs and estimate the additional tax revenue that countries could raise, (3) highlight the main bottlenecks preventing the PICs from further increasing their tax revenue collection with an emphasis on weaknesses in VAT systems, (4) draw lessons from successful emerging and developing countries that have managed to substantially and durably increased their tax revenues, and (5) propose tax policy and revenue administration reform priorities for Pacific Island Countries to boost tax revenues. The paper’s main findings are (1) The current revenue mix is skewed toward non-tax revenues, (2) PICs could collect an additional 3 percent of tax revenue in the short to medium term, (3) Many bottlenecks are preventing the PICs from boosting their tax revenue collection, and (4) The potential offered by efficient VAT systems is not fully exploited. To increase tax revenue in the Pacific Islands, the paper proposes the following reforms: (1) unwinding recent fiscal relief measures, (2) strengthening or introducing a VAT system; (3) rationalizing tax exemptions, (4) closing loopholes in the tax system, (5) reforming tax administration, and (6) introducing a medium-term revenue strategy.
