PKF Wallast originated in Delft and was founded by Mr A.C. Wallast back in 1959. After more than fifty years in the industry, we have developed into a leading tax advisers and accountants group with four different sites.


Our head office is located in Delft. We also operate from our offices in Amsterdam, Rotterdam and Woerden.



The Delft site isn’t only the oldest, but also the biggest of the four sites with its 65 employees. The Delft site has been accommodated in a striking and modern building within the Delftechpark industrial estate since 2004. The site’s clients are based throughout the entire country, with the main emphasis on Delft and its extended area.


Jan Sanders has been Delft’s Site Manager since 1st September 2020. Please go to the ‘Our People’ section if you are looking for details of a particular employee (all employees are listed on the website).
