This study highlights the potential health and economic benefits of sugar-sweetened beverage (SSB) tax implementation in Indonesia. The study employs modeling analysis to project the health and economic impacts of SSB taxes on the burden of type 2 diabetes mellitus (T2DM) over the period of 2024–2033. The 20% selling price increase is assumed to be a proxy for taxes in this study. The findings reveal that taxes would significantly reduce T2DM incidence and mortality over 10 years of implementation. Indonesia could also save up to IDR 40.6 trillion, i.e., the reduction in economic loss associated with T2DM from implementing the taxes.
