Tax revenue as a percentage of Greece's GDP grew by one percentage point to 36.8 percent in 2015, up from 35.8 percent in 2014, the Organisation for Economic Co-operation and Development (OECD) announced on Wednesday.
The increase reflects a continuing reliance on increased taxes - direct and indirect - to meet memorandum-mandated fiscal targets.
In its annual Revenue Statistics 1965-2015 report, the international organization reported that the tax revenue/GDP ratio for its 32 member-states posted a marginal 0.1-percent increase -- to 34.3 percent in 2015 from 34.2 percent in 2014.
Denmark (46.6 percent), France (45 percent) and Belgium (44.8 percent) recorded the highest tax revenue/GDP ratio, while Mexico (17.4 percent), Ireland (23.6 percent) and the US (26.4 percent) the lowest.
