De Facto Anonymised Microdata File on Income Tax Statistics 1998

With the data of the de facto anonymised Income Tax Statistics 1998 (FAST 98), the German official statistics are for the first time publishing microdata from the field of fiscal statistics. The scientific community can use these data to analyse politically-relevant questions on the fiscal and transfer system at their own workplace, subject to the premises of article 16 subsection 6 of the Law on Statistics for Federal Purposes, on the basis of quot;realquot; assessment data. Passing on individual data to the scientific community is only possible in a de facto anonymised form. This form may impair possibilities for scientific analysis possibilities.
