Abstract: The Tax Files which have been produced since 1960 consist of detailed information taken from actual tax returns. The public use versions of these sample files are purchased in an unidentifiable form, with names, Social Security Numbers (SSN), and other similar information omitted. The primary uses made of these files have been to simulate the administrative and revenue impact of tax law changes, as well as to provide general statistical tabulations relating to sources of income and taxes paid by individuals. These data consist of single-year files and a panel that consists of a subset of the single year files (note that not all single-year respondents are in the panel!).
