[ABSTRAK
Tesis ini dibuat untuk mengetahui bagaimana praktik transfer pricing diatur di Indonesia dan untuk mengetahui apakah pengaturan transfer pricing di Indonesia sejalan dengan Undang-Undang Dasar Negara Republik Indonesia tahun 1945 karena melibatkan serangkaian Peraturan Direktur Jenderal. Metode penelitian adalah yuridis normatif. Pengolahan, analisa dan pengumpulan data dalam penelitian ini mempergunakan pendekatan yang bersifat kualitatif, dan hasil dari penelitian ini dituliskan secara deskriptif analisis. Berdasarkan analisis yang telah dilakukan, tesis ini menemukan bahwa praktik transfer pricing di Indonesia secara signifikan diatur oleh serangkaian Peraturan Direktur Jenderal Pajak, dimana menurut Pasal 8 Ayat (1) UU No. 12 Tahun 2011, Direktur Jenderal bukan merupakan lembaga yang berwenang membentuk peraturan perundang-undangan Padahal, Pasal 23A Undang-Undang Negara Republik Indonesia menyebutkan bahwa pajak dan pungutan lain yang bersifat memaksa untuk keperluan negara diatur dalam undang-undang. Dapat disimpulkan bahwa pengaturan transfer pricing tidak sejalan dengan pengaturan Pasal 23A UUD NRI 1945, dan oleh sebab itu tidak memiliki kekuatan hukum yang mengikat. Karena Peraturan Direktur Jenderal pajak tidak memiliki kekuatan hukum mengikat dalam mengatur substansi perpajakan, maka penelitian ini menyarankan ini untuk ditingkatkan levelnya menjadi Peraturan Pemerintah (PP). Hal ini untuk mencegah terjadinya ketidakpastian hukum lebih lanjut.
