The consultancy and service firm of PSP Peintner Seidner & Partner was founded in 2000 by Robert Peintner, an accountant and tax consultant who had been working in Brixen since 1981, together with Paul Seidner, an employment lawyer who had been practicing in Sterzing since 1985, and Wilhelm Obwexer, an accountant and tax consultant from Klausen. This made it possible to offer comprehensive advice in the areas of tax and business law, payroll accounting, and human resources management from the firm’s three locations at Brixen, Sterzing, and Klausen.


In 2002 Markus Wisthaler became the fourth partner to join the firm. Close co-operation between the partners, the use of state-of-the-art software and data processing systems, and the employment of qualified consultants and staff all enabled them to gain the trust of a large clientele.


In 2007 the range of services was expanded to include business consultancy, offering clients comprehensive and professional support in the most diverse economic and tax law issues and problems.


In 2011 the DATAPOOL data processing company owned by Heinrich Eisendle, which could look back on a successful 30-year history, was taken over by PSP Peintner Seidner & Partner.


In 2012 the renowned Bozen law firm of Seidner & Partner, owned by Walter Seidner, as well as its office on the Ritten mountain became part of PSP Peintner Seidner & Partner.


In 2015 the accountant and tax consultant Christian Peintner and the employment law consultants Stephanie Seidner and Josef Radl were accepted into the company as partners. The expertise and experience of these junior partners ensured a constant adaptation to new challenges and at the same time a seamless generational change.


In 2019 PSP Peintner Seidner & Partner became a member of ALLIOTT Group 2019 International, a worldwide network of independent tax and business law firms. This allows clients to have ideal access to information and strategic advice from over 190 member firms in 80 countries around the world to support them towards their growth goals.  


In 2020 the accountant and tax consultant Christian Messner will join the firm as a partner and take over the business and tax consultancy areas of the firm in Sterzing. In addition, KARI, owned by Christian Unterhauser, a successful law firm from the Unterland region of South Tyrol, will become part of PSP Peintner Seidner & Partner.


PSP Peintner Seidner & Partner is today a leading consultancy and service firm for commercial and business consulting, auditing, tax, and employment law advice, accounting, and human resources management in South Tyrol.
