Your trusted partner for 60 years – LeitnerLeitner

For 60 years we have been serving our clients with great success and, thanks to their loyalty, have grown into an international firm. We would like to express our gratitude to all our clients for putting their trust in us. Of course, our thanks also go to our employees – their commitment and exceptional work have played and continue to play a vital role in writing LeitnerLeitner’s success story.

Our history:


In 1959 Dr. Roman Leitner Sr. founded his tax consulting firm in the heart of Urfahr/Linz. From the outset, Dr. Leitner’s focus was on advising family businesses and public bodies, and even then he already laid the foundation for what sets LeitnerLeitner apart today: high-quality, individually tailored and innovative advice and expertise. In the mid-1980s, when the original office was no longer big enough, the firm moved to its current location in Ottensheimer Strasse in Linz.

With the client base growing rapidly, the founder’s two sons, Reinhard Leitner and Dr. Roman Leitner Jr., joined the firm in 1981 and 1983 respectively, thereby also expanding the areas of expertise to include international tax law and criminal tax law.


From the beginning of the 1990s, the firm steadily became more and more international. The main impulse for this was the fall of the Iron Curtain and the associated opening of the eastern borders. In 1991 LeitnerLeitner opened its office in the Czech Republic, followed by offices in Slovakia, Hungary, Slovenia, Croatia, Bosnia, Serbia, and Switzerland.


Meanwhile, things were also going well for LeitnerLeitner in Austria. 1994 saw the firm’s expansion to Vienna, followed by Salzburg in 2004. And last year, Graz became the fourth Austrian city with a LeitnerLeitner office.

Strong partners

International cooperation is a top priority for LeitnerLeitner. We have a long-standing, trust-based relationship with the German law firm Flick Gocke Schaumburg, which is reflected in our many mutual clients. LeitnerLeitner has also been a member of Praxity since 2011 and joined Taxand in 2018. This allows us to offer the best service to our clients around the world.
