The tax firm Assmann had been founded by Mr. Wolfgang Assmann in the year 1950 based on a diversified structure of mandates. One focus had been the taxation of freelancers and especially artists.
His son, Mr. Jörg Assmann, took over the firm in 1990. He continued to do consultation for the existing mandates, but proceeded in increasing the firm and in starting new topics like international taxation right and taxation of bigger companies. With regard to the the international aspects the firm is member of an international network of tax consultants since 2009.
