Legal Representation in Tax Court: Only Advocates Can Accept Power of Attorney

Indonesia’s evolving tax landscape presents complex challenges for businesses, particularly in disputes involving tax authorities. Among the most scrutinized areas are transfer pricing and tax valuation, where authorities rigorously examine intercompany transactions, pricing methodologies, and compliance with the arm’s length principle. Resolving such disputes requires not only strong legal expertise but also a deep understanding of taxation, finance, and corporate valuation to effectively challenge tax authority adjustments.

Following Constitutional Court (Mahkamah Konstitusi/MK) Decision No. 26/PUU-XXI/2023, the Tax Court will be fully placed under the jurisdiction of the Supreme Court (Mahkamah Agung/MA) by 2026. This transition means that tax litigation proceedings will adhere to the general judicial system, reinforcing the necessity of legal professionals in tax disputes. Article 57(1) of Law No. 5/2004 on the Supreme Court mandates that legal representation in cassation and judicial review processes must be handled by a qualified advocate.

Additionally, Law No. 18/2003 on Advocates (Articles 31 & 32) strictly prohibits individuals who are not registered advocates from practicing law, with legal sanctions imposed on violators. These regulations confirm that only licensed advocates may legally accept power of attorney (POA) and represent clients in the Tax Court.
