The OECD has released statistics on the mutual agreement procedure (MAP) caseloads of OECD member countries and certain non-OECD economies for the 2010 reporting period. These statistics reveal a slight decrease in the total number of open MAP cases reported by OECD member countries as compared to the 2009 reporting period. The collection of these statistics forms part of the OECD’s continuing work to improve the timeliness of processing and completing MAP cases under tax treaties and to enhance the transparency of the MAP process.
