Jason’s practice includes:

APAs – Jason advises multinationals in negotiations for unilateral, bilateral and multilateral APAs with the IRS and other tax authorities.

Competent Authority – Jason regularly assists multinationals in resolving transfer pricing and other tax treaty issues through the competent authority process (mutual agreement procedure (MAP)) on favorable terms that avoid double taxation. His competent authority experience is extensive and includes both IRS and foreign government-initiated transfer pricing disputes, as well as issues involving permanent establishments, withholding, residency and limitation on benefits.

Transfer Pricing Planning and Advice – Jason advises multinationals on the tax-efficient structuring of a wide range of related party transactions, including cost sharing arrangements, transfers of tangible and intangible property, intercompany services, financial transactions, and restructurings. In this connection, he frequently structures and advises on intercompany agreements and transfer pricing documentation studies.

Jason is a frequent speaker and author on topics related to transfer pricing, APAs, competent authority and the OECD’s Base Erosion and Profit Shifting (BEPS) and Digital Tax projects.
