Statistics of Income Joint Statistical Research Program

Through its Joint Statistical Research Program (JSRP), Statistics of Income (SOI) seeks to enable the use of tax microdata by qualified researchers outside the federal government. Such research can provide new insights and advance the understanding of the ways that existing tax policies affect individuals, businesses, and the economy. It can also provide a new understanding of taxpayer behavior to aid in the administration of the U.S. tax system. Finally, such research can lead to the development of new datasets useful for future tax administration research, as well as new tabulations that can be released to the public. SOI is a division of the Internal Revenue Service's (IRS) Research, Applied Analytics, and Statistics office.
