Overview

Penezoğlu Law Firm, founded by Yusuf Gokhan Penezoğlu, is a full-service Turkish law firm with a strong focus on tax law. With nearly 25 years of experience, Mr. Penezoğlu has led the transformation of tax law practice in Turkey from accounting to legal expertise. The firm, independent and unaffiliated with foreign entities, serves major multinational clients. Its specialized team handles complex tax disputes and has achieved landmark court decisions. The firm’s deep industry knowledge and client-centric approach distinguish it as a pioneer in Turkish tax litigation and advisory services. 

During the research phase, the firm assisted a software major overseeing both legal and financial structuring of the client's global expansion strategy, managing the end-to-end execution of the project. In addition, the team acts as the primary tax and legal advisor for a multi-year reorganization of one of Turkey’s largest family-owned conglomerates. 

Client feedback

“We have been working with Penezoglu Law Firm for several years and they have been providing us with very valuable advice on a variety of complex matters relating to Tax law. They are very professional, have very experienced and great team.” 

I believe they are the number one law firm in Turkey in the field of taxation. It is truly difficult to find experts in both tax and law in Turkey. Most law firms shy away from any legal matters involving taxes, but this team is not only highly specialized in their field but also acts as our right-hand in every matter.”
