This policy brief discusses fiscal space for UHC in Indonesia by examining the experiences from the financing of Jamkesmas over the period 2005-2012. Analysis of data indicates Jamkesmas financing resulted from generally conducive macro-fiscal conditions and, to some extent, reallocations within the central government health budgetary envelope. Contrary to expectations, financing of Jamkesmas did not result from a central government reprioritization of health at the expense of other sectors. Such financing modalities would be unlikely to be sufficient as Indonesia looks forward to attainment of UHC by 2019. A combination of central government reprioritization of health, efficiency gains, possible earmarked tobacco taxes, and subnational complementary financing will likely be needed to effectively finance attainment of UHC in Indonesia.
