Reports that between June 2012 and June 2013, 32 reforms making it easier or less costly for companies to pay taxes were recorded and 189 recorded since 2009, with Guatemala making the biggest improvement in the ease of paying taxes in the past year. Belarus has advanced the most toward the frontier in regulatory practice in paying taxes since 2008, while among regions, Europe and Central Asia made the biggest improvement in the ease of paying taxes over the past five years. The most common feature of tax reforms in the past five years was to reduce profit tax rates, often in the context of parallel efforts to improve tax compliance, but in the past three years more economies focused on introducing or improving electronic systems. According to World Bank Enterprise Surveys covering 121 economies, in the majority of these economies businesses consider tax rates to be among the top five constraints to their business.
