Tax-funded social health insurance: an analysis of revenue sources, Hungary

Health financing is a complex health system function, which cannot be analysed accurately without tracking each step of the flow of funds separately. We analysed the revenue mix of the Hungarian health insurance fund from 1994 to 2015 and discuss the policy implications of our findings. We used the System of Health Accounts published in 2000 and the revised version of 2011, which introduced separate classifications for the sources of health expenditure. Based on the 2000 version, health insurance contributions were the main source of public funding in Hungary. According to the 2011 version, nearly 70% of health insurance fund revenues came from government tax transfers in 2015, illustrating the striking difference in how revenues and expenditures are reported using this version. Use of the 2011 version will better inform national policy-making and international comparisons and facilitate documentation and analysis of how countries have adapted their revenue mix to changing macroeconomic circumstances. The finding that Hungary has a predominantly tax-funded social health insurance system suggests that traditional understanding and description of health-financing models are no longer adequate and may limit consideration of potential resource-generation options. Hungary is also a good example of how separating revenue generation and pooling broadens policy options to tackle gaps in social health insurance coverage, although the government did not act on these due to the lack of a consistent health-financing strategy. The findings may be particularly relevant for low- and middle-income countries that are trying to expand social health insurance coverage despite limited formal employment.
