Ahdianto is a tax partner with more than 21 years' experience in tax, customs and business consulting. He is a licensed tax court attorney, a licensed customs court attorney and holds Indonesian Customs Expert Certification and Indonesian Tax Brevet Certification (Level C- the highest level). He has in-depth knowledge of national and cross-border issues, and various customs issues.

Ahdianto is a 2017 and 2018 Asia Tax Disputes & Litigation Practice Leader Finalist by International Tax Review (ITR). He led the tax disputes and litigation team of GNV Consulting to win the award as the ITR 2018 Indonesia Tax Disputes & Litigation Firm of the Year.

He is known in the market for his litigation expertise in the Tax Court. Cases that he handles often become a reference for other cases in the Tax Court. His approach in dispute settlement not only focuses on taxation regulations but also combines this with relevant regulations from other institutions or ministries or other law, such as other legislation or civil law, to strengthen the case. Many of the cases that he handles do not have previous cases for reference, so he has to build arguments from scratch with the clients, yet he manages to win the case.

Ahdianto also has extensive knowledge and experience in Indonesian tax and customs (indirect tax). He has engaged in several tax projects such as performing tax diagnostic review, tax disputes settlement, corporate tax restructuring, obtaining tax and customs facilities, tax and customs refunds, bonded zone facility audit and customs review. In the past, he was indirect taxes head with Deloitte Indonesia. He has a broad experience in strategic planning and representation in the Indonesian Tax Court for multinational companies and has served a broad range of multinational companies, including manufacturing, mining companies, financing services, trading services and constructions services.
